• Create lines of master / detail in Application Module Impl

  Hello
  
  I use Studio Edition Version 11.1.2.3.0
  
  I need to create programmatically from the lines of master / detail of a method in my Application Module Impl.
  
  I'm using the code below, but they always tell me that the foreign key is required in the detail row: oracle.jbo.AttrValException: Houston-27014: UserId in UserPreferenceEO attribute is required.
  
  Can anyone recommend the correct way to do this?
  
  Thank you very much

  I had a simular problem a few weeks back.
  To a master VO you must:

  this.getMasterVO().createRow();
  

  And for a VO detail:

  Row row = this.getDetailVO().createRow();
  ...do stuff with the row...
  this.getDetailVO().insertRow(row);

• Problem with application master / detail with AdvancedTable

  Hello
  
  We have a region of master / details in a standard way as follows.
  1. a MasterVO, a child VO, ViewLink connecting them.
  2. on the page, we have an AdvancedTable based on MasterVO and an AdvancedTable nested in a region to show/hide for more details.
  3. in the processRequest() CO, the association is defined as
  OAWebBean outerTable = (OAWebBean) webBean.findChildRecursive ("ResultsTable");
  OAWebBean innerTable = (OAWebBean) webBean.findChildRecursive ("PmtInstructionsTable");
  If (outerTable! = null) {outerTable.setAttributeValue (CHILD_VIEW_ATTRIBUTE_NAME, "PaymentServiceRequestId");
  outerTable.setAttributeValue(VIEW_LINK_NAME,"PsrToPmtInstructionsVL1") ;}
  If (innerTable! = null) {innerTable.setAttributeValue (CHILD_VIEW_ATTRIBUTE_NAME, "PaymentServiceRequestId");
  innerTable.setAttributeValue (VIEW_LINK_NAME, "PsrToPmtInstructionsVL1");
  4. When you press a button to refresh on this table, executeQuery() is called on MasterVO.
  In the test case, I change some attributes in both your. Problem here is that, after this update, the master is on the line is being updated but the detail of any line of MasterVO, is not updated DB. I confirmed this JDev logs too this detail VO query is not executed.
  It is not supposed to have the details updated through VL line?
  Try each of the following:
  a. clearCache() on innerTable
  b. executeQuery() on DetailVO during the refresh.
  c. instead of the programmatic association of the master / detail, defined the relationship of step 3
  
  It seems that AdvancedTable used to detail is cached information. How can this be avoided? Or am I missing something else?

  I had problems with the lines of childVO does not show correctly when you use a train, I have cleared the cache on the table with the following processRequest code

  Table OAAdvancedTableBean = (OAAdvancedTableBean) webBean.findChildRecursive ("childTableRN");
  table.clearCache (pageContext);

  don't know if this will help with your problem but if it's worth a mention.

• Master-detail application

  Hello
  
  
  I have master-detail forms. Master block is filled well the moment of execution request. For my work exfiltration, I have to write code to fill the block of retail. (create relationship does not work with my environment, Master block content from the Web, block detail is the canvas of the tab)
  
  Thank you in advance,
  Murali

  Murali,

  I have master detail Forms. Master block is populated well when execute query. For my working environmemt, I have to write a code to populate detail block. (create relation cannot work with my environment, Master block in content canvas, detail block is Tab canvas)
  

  It would be interesting to learn more about your 'working environment' which prevents you from using the native functionality of Oracle Forms. You get an error when you try to use the relationship as Francis suggested?

  In all cases, you can manually code if you REALLY want to; However, you will lose any functionality auto-synchronizition in doing this manually. What I mean by automatic synchronization is; If you select a record in the block Master - detail block is automatically synchronized with the selected record.

  In your code when you call the built-in Execute_Query simply navigate to the detail block; the value of any WHERE clause you need to connect the retail block in the main block and run a query on the block of retail. Finally, you navigate back to the main block. For example:

  /* Example When-New-Block-Instance trigger  */
  DECLARE
       v_Def_Where          VARCHAR2(1000);
  BEGIN
       /* Other code here.... */
       -- it is assumed you are already in the Master Block at this point
       Execute_Query;
  
       /* Now - go to the detail block and execute query */
       Go_Block('My_Detail_Block');
       v_Def_Where := 'UNIQUE_ID = :Master_Block.Unique_ID';
       Set_Block_Property('My_Detail_Block',ONETIME_WHERE,v_Def_Where);
       Execute_Query;
  
       /* Now go back to where we started from. */
       Go_Block('Master_Block');
  
       /* Other coordination code here...*/
  END;
  

  You will need to run code similar to this whenever you change records if you want your main and synchronized blocks between them.

  If you get an error when you try to use a relationship, it would be worth it to try to resolve the error rather than try and maintain the master - coordinating block details manually in your code.

  I hope this helps.
  Craig...

• Import/Export of master detail Page lose columns on the MRU

  When I export and then import my request, master details page loses column on retail MRU on Version 4.2.3.00.08

• Form master / detail apex 5 tries to update the lines of details without apparent change

  A form master / detail of Apex default 5.0 creates buttons back and forward on the main table. When you move between records, the detail region launches a message: update 0 row (s), 0 or the inserted rows.

  Glance in occasional of the user, it will look like a mistake: I, what has changed and why it has not been saved?

  If nothing has changed, why is a MRU statement update being generated?

• Master-detail - page updated

  Hi all

  I implement updated for logic with master-detail page.

  My expectations:

  Both master Vo and Vo of detail is executed with Set whereclause and line master and detail gets displayed.

  The two actions are required in the application process.

  Result:

  Executing query (even after call run the query for master and detail VO), master line get appears. Detail line is not displayed,

  

  However when the form application process is called (by clicking on the button Save), detail lines gets displayed.

  My logic to query example: (your have VL and EOs have AO)

  PR:

  Configuration where clause;

  XXAM.getXxcfirIcfUpMasterVO1 () .executeQuery ();

  XXAM.getXxcfirIcfUpDetailVO1 () .executeQuery ();

  PFR:

  The logic of adding new line-to-line in detail.

  Save button.

  Is there a way to show line main and details while that Page gets loaded through the application process and still not break the relation ship master detail since must be made on the update page.

  Thank you and best regards,

• Master / detail createInsert jumping required attributes validation with part delivery = true

  Hi all

  I use JDev 11.1.1.7.0

  I created master / detail on table emp dept and slipped and fell from CreateInsert in both tables.

  I put partial Submit true for these two buttons.

  Scenario: when I add a record in the master and try to add another rec, mandatory validation fires and it doesnot allow me to add new rec if already a rec void is there.

  But after adding in master, if I add a new rec in child, isn't shooting the validation of required attributes in the parent table. So a new blank record is created is in the child. ]

  If I put part delivery = false for child createInsert, fires of validation.

  Question: in my application, I set partialSubmit = true to CreateInsert child. Although I gave the partial trigger for the main table, validation of required attributes is not get fired for master.

  How to solve this? User should not be able to add a record of the child without filling out the required attributes

• 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.

  If the AM pooling is enabled, no errors...

  No idea what means this exception?

  I use JDev 11.1.1.7, let me know if you need additional information on the VO, entity or something else...

  Many thanks for the suggestions,

  So what solved my problem was simply uncheck the "cascade update key attributes" relative to the association (composition). I still don't understand why that would be a problem to check if...

  No restrictions on Association (composition) with the option "Cascade update key attributes" checked when passivation/activation takes place on a newly created on two line master-detail VO?

• 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

  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.

• Master / detail Edit - any form of detail is displayed on the page?

  I have a simple application, built on a master of table BPR_PROC (a single column, PROC_NM). And a secondary table BPR_RUN (PROC_NM columns and a few others). There are only 4 pages: (1 House, Master 2, 3, 4 Login details). I did this as a standard form - create selection master / detail.
  
  When I create or edit a master (PBR_PROC), the mounting happens on details page - well, very well so far. But no form is displayed with the detail rows exist (according to the BPR_RUN of detail table) or whatever it is for me to go into details. (I'm sure I've done app M - d. before and the change of details form appears at the bottom of the details page but I am noit do here).
  
  Question: How can I fix to add / modify detail rows?
  
  WS: APEX_EXAMPLES_01
  User: demo
  PW: demo
  Appl: BPR_991203
  
  Thank you
  Howard
  
  (For later: Question: is there a simple way to do the master editing on master rather than on the detail page?)

  Ah! I've recreated the problem - this time on pages 12 & 13 and as before

  the point value / Expression 1 Is NOT NULL column condition on the detail region seems to lack a little:

  So, it's a "bug"?

  Probably something to do with the creation of forms of master-detail using ROWID instead of a real process of generated by the wizard of PK. APEX theory. PKs relational DB meaningful, immutable like immutable PKs. Despite the bug condition region of detail, is why your column editable PROC_NM if it is used as the PK? It is a good way to break things. (I created now orphaned detail rows).

  If you want to take advantage of the built-in features of APEX as ARP and MRU wizard-generated process, then go with the flow: use surrogate keys. Otherwise you'll spend your time to write a lot of code manual.

• 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:

• Failed to add new detail in the form of master detail record

  Hello
  
  I created a simple database application from scratch by selecting the start a page master detail. This has generated a report (for the parent) and a page of form (for the child). On using the form to add a new record to the child, the following error is generated:
  
  Internal error in the routine mru: ORA-20001: error in MRU: line = 1, ORA-01400: cannot insert NULL into ("Student" 1.) "" DELEGATE. " "" ""DELEGATE_ID"), insert"Student"1." DELEGATE values' ('DELEGATE_ID', 'CLIENT_ID', 'NAME', 'INITIAL', 'SEX', "SPECIAL_NEEDS") (: b1,: b2,: b3: b4,: b5,: b6)
  Error failed to process the update.
  
  The field 'child' in the error message is automatically hidden on the form and I guess on the generation of this form using the wizard I would have had the opportunity to link the field delegate_id to a trigger or a sequence like this seems to happen when you create a scratch from application database using other types of page. I'm new to Apex then I would be grateful if someone could let me know why this default behavior occurs.
  
  Kind regards
  
  Kevin.

  I tried for Apex 4.0.2 (my version) and 4.1 (on apex.oracle.com) and I'm wondering for the production of main PK and details in both versions.

  What are your steps exactly in the wizard? Like this?
  Create page-> form-> form detailed Master
  Now you see a list of steps sub whose "Source of primary key.

  Oh I see "Create an Application Assistant." in your message. Start with an empty application (blank page) and use the wizard to create a Page. Maybe it's the difference.
