• Display of a relationship master detail in an accordion panel or tabs

  Hello
  
  Is it possible to display a relationship master / detail in an accordion in the Panel, Panel tab or other component that visually separates the display?
  
  I have a Ministry - > employee master detail relationship and I want that every tab in my accordion to represent each
  departments and when I clicked on the tab, the list of employees related to this Ministry.
  
  I explore this idea, but I can't seem to find a resource on how to move forward. I use JDev 11.1.1.4. Thank you

  Hello

  I recently faced the same problem and did not find a solution either. So I set up a little more "dirty". :-)

  Instead of use the Department > employee link, I just created a new view (say EmployeesFromDept) object, which has a binding parameter called p_DeptId:

       SELECT ...
       FROM   EMPLOYEES e
       WHERE  e.DEPARTMENT_ID = :p_DeptId
  

  The data from that OV control will have an ExecuteWithParams operation that takes the id of service as input. Create a binding action in your definition of page that binds to this operation, called "RefreshEmployeesForDept":

  In your page, add the current DepartmentId to each showDetailItem using an attribute and add a disclosureListener:

       
              
  
                 
                 ...
                            
                 //Lots of mapping column here
                      
  
              
       
  

  Now, each showDetailItem which is generated knows the DepartmentId he "belongs to". In the toggleDisclosed(DisclosureEvent disclosureEvent) method, first get this attribute, so that you know the id dept of the showDetailItem that has been clicked. Then, call the action of RefreshEmployeesForDept programmatically binding if the current event is "disclosing the showDetailItem ':

       public void toggleDisclosed(DisclosureEvent disclosureEvent) {
            String currentDepartmentId = disclosureEvent.getComponent().getAttributes().get("currentDepartmentId").toString();
  
            if(disclosureEvent.isExpanded()){
                 DCBindingContainer bindings = (DCBindingContainer)BindingContext.getCurrent().getCurrentBindingsEntry();
  
                 OperationBinding operBinding = bindings.getOperationBinding("RefreshEmployeesForDept");
  
                 if(operBinding != null){
                      operBinding.getParamsMap().put("p_DeptId", currentDepartmentId);
                      operBinding.execute();
                 }
            }
      }
  

  Now, whenever a showDetailItem is open, the variable binding of the iterator belonging to your employee list will be updated with the correct DepartmentId. That is to say the Department that represents the showDetailItem.

  I hope this helps! If you find a solution cleaner, please let me know. :-)

• Cannot create relationship master detail for datablock

  Hi guys, my form currently has a relationship master detail for 1 datablock and everything works well. I now have a need to do a datablock different, based on the same table as the previous datablock but for some reason any that it won't let me create the same master-detail relationships, as I did on the 1st slice (and I need the same relationships to sort the block shows the same data as the previous datablock).
  
  Anyone know why it won't let me create the relationship?

  I encountered a similar problem before. When you say that you cannot create relationships is - it simply because you cannot select the master/detail through the wizard? If this is the case, you should be able to make the relationship manually, or at least I could when I had the same problem. Although I can't help, but wonder why it wouldn't let you select them in the wizard. There may be an underlying reason for this. But anyway, try and make the relationship manually and let me know if it works.

• How can I download multiple files in a relationship master detail?

  I would like to be able to download several files to a record (one to many). I tried to use a form master detail, but the form of tables does not support browse file. I searched the forum and found several examples asking how to download multiple files at the same time. This is not what I'm trying to do. I just want the user to browse, select a file, provide a file name and description. Then select the next file. When they are made by selecting the files (it can be one or more files) I want to that they hit the button send and I'll run a procedure that saves files in the database.
  
  How can I do this? Thanks, you're the best. Elizabeth

  Elizabeth,

  I had this situation come once and here is what I did, thought, may not be exactly what you are looking for.

  I created a collection to store the ID of files that had been transferred, as well as the key, and other information. Her search for an input file will transfer your files in the table wwv_flow_files on submit. I store the documents in another table of the application.

  The after submit process captures the id of wwv_flow_files where the name is = to your input file.

  After you add this ID and your master key associated with the collection, your last submit process retrieves files from wwv_flow_files and inserts them into your own table.

  I put an example on apex.oracle.com if that would be helpful.

  Thank you

• How to create a dependent list of values based on the relationship master detail

  Hello

  I'm on jdev 11.1.2.4.

  1. I have a table main 'Reception' with the columns receipt_id and student_id (ReceiptVO)

  2. as well as an array of details 'Receipt_Detail' with the columns receipt_id, course_id (ReceiptDetailVO)

  (There are some othere columns in the two tables, but I've only mentioned those which is relevant to this example.)

  3. the two tables are related with receipt_id.

  I want to create a dependent class LOV that filter courses related to the student selected in the main table. (There is a student_course table that holds student_id, relationship of course_id, StudentCourseVO)

  to do this, I have

  1 created VO based on the student_course table

  2 Add a view that filters based on the id of the student

  3 assigned this VO to receipt_detail tables course_id

  It comes

  in the accessor receipt_details VO view, I do not show the ability to select the student_id of the main table (IE ReceiptVO). It only shows the columns in the ReceiptDetailVO.

  Please can you help me?

  Thank you

  What you need in your ReceiptDetailVO is the StudentId of master ReceiptVO attribute.

  To do this, you can:

  1. for your ViewLink (between ReceiptVO and ReceiptDetailVO), you must generate the Source accessor:

  

  In this way, in the VoRowImpl Java to ReceiptDetailVO class, you will get a way to access master ReceiptVO line (you can find a new method with the name that you gave the name of the accessor in the top of the dialog box)

  2. then, in the ReceiptDetailVO, create Transient attribute, say, MasterStudentId. Access Java's VORowImpl class, within the get for this new attribute accessor method, use the previous step name accessor method to get the line main and finally master StudentId.

  3. the rest is easy - use this new attribute transitional to filter LOV about the student teacher ID...

  With the help of forms [32 bit] Version 10.1.2.2.0 (Production) Oracle9i Enterprise Edition Release 9.2.0.8.0 - 64 bit Production.
  
  I have the following problem with a form that I'm working on. It has a block of data base with several blocks of detail data. I'm trying to create a trigger after query on one of these blocks of detail that will make a select using the value of one field of one of the blocks in detail.
  
  The problem that is the trigger after query of the data block with the fact that I'm doing the selection before triggers the shutter after request of the block that I need the value. I tested by simply putting in a message on the screen and it returns the value of the id I'm tryign to use. Just after I do a query on the form, I get messages saying:
  
  «Error: can not find the price for the id: "and there no identity and then the message of the other revenge after request by saying," id is: 123 "»»»
  
  Is it possible to change the order that the revenge indicate if they want to? Or should I use a different trigger to do?

  Hello!

  Take a look at the trigger WE-PEOPLE-DETAILS of your master block.

  Look where the Eastern bloc, you must be questioned in the first order.
  Place the above code the other sections of the block program.

  Be careful. May first make a copy of the trigger.

• Strange problem in relationship master detail

  I have a form of purchase order that contains the editable for invoice line table. I have a commandButton control in PanelCollection surrounding table that inserts the new row into the table by running the createInsert operation. I save the purchase order including those running a business defined in ApplicationModule anyway. In this process I download the order form and assigns a primary key for buy order and the elements of each line. Now the problem is that when I enter a single line item, I get 0 topic in my business method but when I get home from two or more line items, I am everything. I get headings and order form by using the findViewObject method. Kindly help me

  I remember now that you work with JDev 11 g, then the correct Developer's guide would be called something like "the fusion developer guide.

  In the manual of 10g I was talking (B25947_01) is 26.7 section I was talking about. Here's the intro to this section:
  26.7 entity control validation of order to avoid constraint Violations
  Due to data constraints, when you perform DML operations to save changes to a
  number of entity associated with objects in the same transaction, the order in which the
  operations may be important. If you try to insert a new line containing
  references to foreign keys before inserting the line referenced, the database can
  to complain of a constraint violation. This section helps you understand the default
  prescription for the treatment of objects of entity at validation and how to
  programmatically influence this order when necessary.

  I understand that this problem is not an exact match to your question, but I have the feeling that something about this causing you problems.

• master/detail relationship through two workflow

  Hello world

  I use jdev 11.1.1.7.0.

  In my application, I created a relationship master-detail between departments and employees (departments is master and employees is detail). Then, I created two stubborn workflow.

  Department-stream with a department.jsff and I drag / drop the departmentVO as a form.

  

  employee-stream with an employee.jsff, on this page I drag / drop employeeVO located under departmentVO in the control panel of data:

  

  can I use these two TFs (Department-flow and employee-flow) through two different ways

  1- I create a main.jspx page and I put two TFs as an area on main.jspx.

        <af:form id="f1">
          <af:region value="#{bindings.departmentflow1.regionModel}" id="r1"/>
          <af:region value="#{bindings.employeeflow1.regionModel}" id="r2"
                     partialTriggers="::r1"/>
        </af:form>
  
  

  in this case when I run the homepage, two TFs are in sync with each other, I mean when I navigate between departments in the workflow Department, employees in the employee flows are discount

  and also if I enlist in the workflow Department then changes in the flow of employee will be validated.

  2- in this case first I create a master stream with an master.jsff and then I put two TFs as an area on master.jsff.

   <jsp:root xmlns:jsp="http://java.sun.com/JSP/Page" version="2.1"
            xmlns:af="http://xmlns.oracle.com/adf/faces/rich">
    <af:region value="#{bindings.departmentflow1.regionModel}" id="r1"/>
    <af:region value="#{bindings.employeeflow1.regionModel}" id="r2"
               partialTriggers="::r1"/>
  </jsp:root>
  
  

  and finally I put flow master as a region on the page main.jspx.

         <af:form id="f1">
          <af:region value="#{bindings.masterflow1.regionModel}" id="r1"/>
        </af:form>
  
  

  in this case, when I run the main.jspx , always the two page two TFs are in sync with each other (updating of employees when I navigate between departments)

  but in this case the validation in the workflow Department commit not changes in the flow of employee.

  Anyone know how I can I have this (validation cause Department-stream flow used as case 1)?

  Habib

  Concerning

  Habib,

  I just did what you said.

  1. Ran the mainWithMasterFlow.jspx,

  2. the Department rendered initially has only one employee.

  3. has changed the salary. (Kept the emphasis placed in the same field)

  4 click "Commit".

  Above scenario failed, because the change in value has not been submitted. Try adding autoSubmit = true for the salary field and then repeat the procedure, you will see the file be saved.

• Relationship need master / detail to post a link Master column to the different retail pass 2

  I have a form with a relationship master detail. The main block is a rec_shipments of table of database with a primary key of the shipment_id and a bunch of other columns. The retail block is a rec_containers table with a container_id as the primary key most column shipment_id, split_shipment_id, weight, volume, etc. The shipment_id and the split_shipment_id are nullable.
  
  When a shipment is received a shipping record is created and container records are created with the populous shipment_id and the split_shipment_id null. Under the shape of what a relationship is created between the block of the expedition and the block container as shipment_id = shipment_id. It works very well. However, they have the ability to spit the original containers in small containers easier to manage for the distribution. For example, if they receive a railroad car full of pallets of printer paper they can take and divide the, 1 tray of rolloff half-and-half into another tray of mitigation. The bins of rolloff will get a unique container_id for follow-up. Registration in the system created in the rec_containers table will be the populous split_shipment_id and the shipment_id null. On the screen, they want to see the (railroad car) original containers and containers of split (ferries rolloff) when the query expedition.
  
  What they want:
  Shipment_id - and additional information
  ID drive to railway and additional information
  Rolloff Bin 1 ID and additional information
  Rolloff Bin 2 ID and additional information
  
  My problem is the attenuation of bins do not arise with the current relationship because the shipment_id is set to null in the 2 files of bin rolloff.
  
  I tried to create a view on the rec_containers table that is all columns in the table plus 1 additional column which is
  NVL (shipment_id, split_shipment_id) comp_ship_id
  
  then assign the relationship shipment_id = comp_shipment_id. I have the comp_shipment_id column value query Yes and insert & update or not because I don't want to not update this column in the view.
  
  The problem is I can't update all the columns, I get a cannot book record to update or delete the error.
  
  Does anyone have any ideas how I can get the block of containers to query all records where the shipment_id or the split_shipment_id is shipping block shipment_id and still be able to update the records?
  
  Thanks for any help.

  Your idea of using a view is the best approach. To perform the update block, you have OHS 'Query' property only for your item derived to 'yes '. Witn, the column will not appear in any other dml. On lock... maybe the forms is no longer able to make a regular blocking when a block is based on a view. In this case, put a LOCK ON trigger on the block and lock the record for yourself to SELECT for NOWAIT UPDATE on registration. Just try if it would work, you use a NULL value in the POCKET ON right to xheck if dml himself operations will work. If your view is based on a single table, you have a good chance that there is nothing to change, if you get an error like 'Unmodifiable view', you need to make some additional adjustments
  -Choose the Mode key for the block to 'uneditable '.
  -Set the 'primary key' property to 'Yes' for the pk-point in your block.

  hope this helps

• Master - Detail of the object View and Javabean

  I have a table with data from VO (database, let's say in table A). This table has Id, name and processId table. I also have a second table below the first table, what data comes from a javabean (source data not DB). I created this bean data control, which in turn, I created the second table.
  What I want to achieve, it is when a user to select a row in the first table, I wish that the second table is updated according to the processId value of the selected row in the first table.
  Would you share how to do it?
  
  Thank you.

  Hello

  my Oracle Magazine July/August 2012 column covers a similar use case of Web Services that work in a relationship master / detail with ADF business components view objects. In this article I recommend using the programmatic view objects and entities that this ensures the consistency of the master / detail is handled by the template and cannot be controlled manually on the view layer. I think that the possibility of using a JavaBean domain controller and synchronize it with the object View is a valid option, however, if the rest of your application using ADF business components then I would consider programmatic view objects (and entities if the app is CRUD to the POJO too)

  Here's a sample and a good report:

• Problems on master detail CRUD

  Dear all,
  
  I'm trying to understand how ADFBC manages the relationship master detail like this
  is the first time where I need to manage the table relation.
  Practice, I only used a table but this time I need to manage the relationship, too.
  
  I have two tables that follow. They have a to-many.
  PART_ID in the PARTS_CODE table is filled by a sequence of DB.

  PARTS_CODE                                   PART_DESC
       - PART_ID (PK)                              - PART_ID (PK)
       - RANGE                                   - REGION  (PK)
       - CATEGORY                              - DESC

  Use case is like this:
  Table PARTS_CODE contains data on the parties while PARTS_DESC contains information on the description of the specific region of the parts.
  
  Now, I created a View object that links the two tables. Then I drag this display object from
  my data as a control table update-able.
  
  I just have a few questions on the implementations:
  1 when I drag and drop the CreateInsert button and click on it, I noticed that it adds a new line to the
  table, but I noticed that it creates the Text Input component only on the associated columns
  the PARTS_CODE Table, the other columns for the PART_DESC does not have the user interface components.
  How to solve this problem?
  
  2. how to manage the relationship such that when it inserts the data on the PARTS_CODE, I need
  to get the DB generated sequence number and put it in the PART_DESC table
  
  3. any demonstration/links which shows the CRUD operations involving arrays of master detail?
  
  I searched the forum for Crud master / detail, but I can only see the display of the relationship and not
  CRUD operations.
  
  Found this blog too http://andrejusb.blogspot.com/2009/03/create-operation-for-master-detail.html, but
  I can't even fully understand.

  Thank you

  You will need to create a black and white view link in your main table and details. The blog provides the code example if you step through the code, you will get to know exactly how it's done.

• Master - detail reports

  Hi, Im currently produces a report of which the data are obtained from 2 views I created on the database. We can look at this as a relationship master detail. Basically I have a view with details of staf and views with all the details of the client. 1 staff member can have many clients asociated with them. This is related to a reservation id. If the staff and clients have the same reservation id they are so related.
  
  I have implemented this in the reports in the following way:
  
  
  I have a nonrepeating framework encapsulating everything. then this frame is divided into a left and right, the left side is an extensible framework with the details of the staff and the right side is an extensible framework with the details of the client.
  
  I want to be able to see is the details of staff then beside that the details of the customer like this:
  
  (.' are spaces - just used to show the layout)
  
  staff ID | staff name. staff * | staff * client id | name of the customer. customer * | customer *.
  .............................................customer id | name of the customer. customer * | customer *.
  .............................................customer id | name of the customer. customer * | customer *.
  
  But as I have at the minute im just get:
  
  staff ID | staff name. staff * | staff * client id | name of the customer. customer * | customer *.
  staff ID | staff name. staff * | staff * client id | name of the customer. customer * | customer *.
  staff ID | staff name. staff * | staff * client id | name of the customer. customer * | customer *.
  
  They do not seem to be linked is there a way to link the master details? I have already created the relationship in the querys etc. my problem, I feel lies in the way I set up the report, its basically just go to each view and bring back the reguardless of the relationship data.
  
  Any help would be much appreciated.
  
  Thank you.

• How to create the column of the table for long-form Master detail relationship

  Apex 4.1

  Oracle 11g

  I created a form master detail and see the main table hotel_list and table hotel_mapping as detailed below.

  Hotel_list

  ID HOTEL_NAME

  1 Holiday Inn

  Hotel Hilton 2

  Hotel_mapping

  ID HOTEL_NAME MAPPING_NAME

  1 Inn Holiday Inn Select hotel

  2 holiday hotel Holiday Inn Select

  3 hotel Holiday Inn Holiday Inn Hotel

  4 Hilton Hotel Hilton Hotel chain

  Hotel Hilton 5 HiltonHotel

  Table Hotel_name Hotel_list is a linked table Hotel_mapping

  When I add a line to the Hotel_mapping table for the selected row in the hotel_list table, mapping_name of column is null, therefore impossible to create the relationship between the main table and the secondary table.

  I would like to know, how to create the relationship?

  Thank you very much

  Best regards

  Yong Huang,

  simple step see creating a form detailed master with APEX - Assistant Master retail

  and check how to maintain the relationship between two tables,

  simple return the packaged application «Sample of Masters details»

  and try to understand this concept...

  In your example, use Hotel_list.ID as a foreign key in the table Hotel_mapping

  and maintain the relationship with the column ID...

  and choose the display type of the column Hotel_list.ID in table Hotel_mapping as List(Query Based LOV) select.

  otherwise the best way is to create sample on oracle.apex.com

  I hope this helps...

  Leave.
