• Master / detail: several lines in detail are selected default

  Hello world

  I use Jdev 12 c and facing a problem, in a scenario of master / detail, several lines are by default selected in the secondary table, I checked the line selection unique option in the configuration of the table. Please see the snapshot for clarity.

  

  Help, please

  Kind regards

  You normally see this problem when the vo or eo is not a primary key defined. Check that each OT and vo should have a defined primary key that is unique for the vo.

• MASTER DETAIL - SET THE DEFAULT VALUES FOR ELEMENTS

  I have a page master detail where, on the master, I do things like update the fields entered_by and entered_date
  by applying functions to define item-level details and the read-only setting.
  
  On the portion of the page detail, I would do the same thing, but I don't see the point of page details - only master items.
  The portion of details is for comments so I wish I had the commenter_name and commenter_date the value of the values
  When I hit the Add button line on the portion of details.
  
  Where are the elements of detail?
  
  I use APEX 3.2
  
  Thank you

  Hello

  When you use the master detail form, APEX build "Detail part" in the report. So if you edit the page, you won't see actual items for 'Party detail'

  If you want to set default values or want to format these items, you may need to perform like this

  1 > edit 'report' of the "retail portion.
  2 > click on attributes report
  3 > click on the column, you want to set default values
  4 > now here, in accordance with article 'Tabular form Element' you can do this by setting appropriate in 'default' type fields and "default".

  It may be useful

  See you soon

• 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?

  How do I remove this behavior? Is this a bug?

  You can see in https://apex.oracle.com/pls/apex/f?p=74308:LOGIN_DESKTOP:113903018138704:, the application of MasterDetail Claim_Charge. Credentials are of assistance/Viewer.

  Thank you!

  Hello

  Create a new hidden element Px_RUN_MRU and the value of

  Source used "Always replace the value that exists in the session state."

  Source of Type ' static assignment (the value corresponds to the source attribute) ' and

  Value of source or phrase "N".

  Then create new PL/SQL process for tabular and use the code

  if :Px_RUN_MRU = 'N' and :APEX$ROW_STATUS IN('C', 'U', 'D') then
    :Px_RUN_MRU := 'Y';
  end if;
  

  Make sure that this process is captured in the form of process MRU.

  Then change tabular MRU to love affection

  (:request like ('SAVE') or :request like 'GET_NEXT%' or :request like 'GET_PREV%')
  and :Px_RUN_MRU = 'Y'

• Issue of ADF 12.1.3 [master / detail + Association + JSF]

  Greetings, community!

  There are 2 ViewObjects and ViewLink, based on EntityObjects and Association. They are master / detail 1-to-many.

  All MasterEntityFields are generated automatically. AutoSubmit set to true in the two viewObjects.

  In BCTester:

  (1) create the master record.

  (2) create the detail record.

  (3) put data in the detail record.

  (4) commit.

  Everything works fine.

  On the jsf page (datacontrols were generated by generation jDeveloper by default):

  (1) master CreateInsert.

  (2) retail CreateInsert.

  (3) put data in the detail record.

  4) commit - here's a mistake about database constraint violated, attempts to insert the details when there is no master.

  Solution: In the form of master focus to any field, change the value. Press 'Validation' again, and it works fine.

  So that trials of this question, I did everything that comes to mind, the value record everywhere and clearly given master, it creates, it is fine and it is valid.

  This can be a JSF/bug problem when working with auto-generated documents?

  Reading one size does not fit all: ADF BC: EO/VO State initial post create() explained and Andrejus Baranovskis Blog: difference between initialized and new Mode ADF BC

  That should give you an explanation why this happens.

• Form master-detail recording detail does not with ORA-20001

  Hello
  
  I have a master/detail form, the detail record has a timestamp field that I people using systimestamp via the default, it is a single field of view and everthing records very well. But if I change the format of the timestamp field via the DD-MON-YY HH24 attrubutes column, I get the following error on save
  
  Internal error in the routine mru: ORA-20001: error in MRU: line = 1, ORA-20001: find the invalid timestamp value, please check the timestamp format.
  
  Someone knows what's goin?
  
  Thank you...

  Looks like your display only column is based on the database column.
  If this is the case, you have little control for it in ApplyMRU.
  What you need to do is
  a. keep the TimeStamp column hidden with any mask format
  b. Add the form as a table with the format mask you want to display a column of data not

  In a Word, the DB column is in the proper format as required by the ApplyMRU but you display for users of the truncated version of that.

• 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.

• Using wizard to create forms of master / detail

  Hi guys,.
  
  I'm using JHeadstart 11.1.1.3.35 and having major problems trying to create records of master / details in a layout of the wizard
  
  Department Master (shape, style Assistant, insert enabled, new line on entry)
  Group of retail employees (form, data dependant, allowed insert, update has allowed)
  
  Using schema HR with a view link between services and employees
  
  Main group Department (Assistant)
  = > Region of the element (all the fields of the Department)
  = > Region container
  = > Region group (Group of retail employees)
  
  (NB - if I used a group of the region as step in the wizard at a higher level, the following error occurred during the generation which is why I wrapped it in a container of the region...
  
  [NewDepartmentNewEmp.jsff, default/pageComponent/formRegionGroup.vm] Journal of speed [error] method pushModelPointer threw the exception of reference $JHS for model default/pageComponent/formRegionGroup.vm at [1,1]
  [NewDepartmentNewEmp.jsff, default/pageComponent/formRegionGroup.vm] org.apache.velocity.exception.MethodInvocationException: Invocation of method 'pushModelPointer' in class oracle.jheadstart.dt.jag.engine.velocity.JagEngineFacade threw exception class java.lang.NullPointerException: null
  
  The problem is that the detail of employee group does not start in design mode.
  
  I tried the create() method substitution in DepartmentsImpl
  
  protected void create (AttributeList attributeList) {}
  Super.Create (AttributeList);
  
  NewEmployee RowIterator = this.getEmployees ();
  NewRow row = newEmployee.createRow ();
  newEmployee.insertRow (newRow);
  }
  
  I also tried the override of the executeQueryForCollection method in detail (saw this solution suggested in another post on creating a form-form master / detail)
  
  protected void executeQueryForCollection (Object, object,
  Object [] bindParams,
  int i) {}
  super.executeQueryForCollection (object, bindParams, i);
  If (getEstimatedRowCount() == 0) {}
  Line = createRow().
  insertRow (row);
  row.setNewRowState (Row.STATUS_INITIALIZED);
  }
  }
  
  Nothing works well. I want to be able to use a wizard to create a record of master / detail in presentation view shape-to-shape. Is it possible, using a detail group, or do I have to create a separate view object that contains two master entity objects / detail in it and then just use the only VO in the Group Assistant of JHeadstart.
  
  This seems a very basic requirement, I clearly do something wrong!
  
  See you soon,.

  Brent,

  To start in design mode, you must create the Group NewDeptEMp as a top-level group, so he will have his own taskflow. You can then define the new display line on the input property.

  In your wizard NewDept, you create a group of the region DIRECTLY under the container of the separatePages region, check "Include as ADFc region" then select the NewDeptEMp group.

  To work around the error that you got during the generation of the group in the region as an immediate child of the container sepeartePages, use the following code to formGroupRegion.vm:

• Spry experiments Panel tabs and master/detail Page Set

  Hello

  I created a feedback form and uses a Spry tabs Panel to allow users to review the answers to a question and then answers the question in different tabs, there are 6 tabs at all. In every tab I have created a Master / Detail Page set - well actually just the master appears in the tab. It works very well. I'm up to 20 answers to appear on every page, after which the user selects first/previous/next/last. When they do the screen refreshes and the tabs panel display goes back to the tab by default, clicking on the previously used tab correctly displays according to of first/previous/next/last selected user. I would like that the display to stay on the user's current tab when they select the first/previous/next/last.

  The page in question is here http://www.hollisterairshow.com/feedback-results2.php, then scroll to halfway to the bottom of the page.

  Thank you.

• All master detail...

  Hello
  
  
  I m new in Apex, I have the tables T1 and T2 (master/detail) T1.ID = T2.ID is easy using the wizard, my problem is "when the user clicks the Add line buttom in the retail area, the action is to create a new line for table T2, I need to fill out some columns (T2) automatically, ei, T2. DATE-> sysdate, T2. USER-> #OWNER #, please I need some advice in order to solve this problem...
  
  Thank you

  Set to true, Tony. My answer was assuming programming experience. It also leaves open the option to default to a value that the user is able to change (even if the two examples given in the original post are probably not something that the user should be handle); triggers would force a value without allowing the users to substitute them.

• Get details about the form master / detail

  Hello
  I use forms6i.
  I have a clarification on master form / retail.
  If suppose a form with 2 revenge (block master / details) inside.
  We run the form and enter a few details in the main block, and then in the block of details, and so we try to navigate to the record next to the master.
  If he asks "do you want to save the changes?" before moving to the next main record?
  
  Why I ask, this is where we use the model, and she asked you want to save.
  (Even without a model also I get the same).
  Just to confirm if it is the default customer forms and may be in my forms goods are prepared, so that it can behave this way.

  You can issue a MESSAGE in the on-CLEAR-DETAILS-the trigger, this "will save" data in the database, without actually committing.

• Attribute DetailFlag in master/detail

  I want that the detail rows of a master-detail table to be expanded initially when the page is displayed. I saw the previous posts, referring to the updating of the 'default' value for the attribute 'DetailFlag' of the view. I tried this to be put in 'Y' or '1', depending on the type (string vs Boolean) but it didn't work. Can someone please offer another suggestion?
  
  Kind regards
  LC
  
  Published by: user12026657 on August 12, 2010 06:40

  instead of providing the default value you can explicitly set the attribute y after the execution of the query on the VO.

• Master detail form based on single Table

  Hi all.
  I have a table like
  
  daily_transaction
  (
  TRANSACTION_DATE DATE,
  LINE_ID NUMBER,
  ITEM_CODE VARCHAR2 (10),
  NUMBER OF BALANCE,
  DESCRIPTION VARCHAR2 (500)
  )
  
  Now, I want to build form master detail
  
  master form have only transaction Date all in the form of retail have row id, item, balance, date of transaction, description code
  
  I join date of the main transaction with the date of the transaction in detail
  
  now the problem is when I enter two archives in the form and save it, it save 3 record in the table, an empty line except transaction date
  Please guide me how to save two archives:
  
  Secondly when I update / edit date of master on the date of the operation blank line change, how do I update details form

  In order to perform an update on a view - it must be a "editable view. You try to update the MASTER block (based on the view)? Otherwise, make sure that you change the property update block allowed to 'No' as it is default to 'yes '. If you do not update the MASTER block, make sure that your point of view is "can". Read this article from Tom ask article on editable views. http://asktom.Oracle.com/pls/asktom/f?p=100:11:0:P11_QUESTION_ID:5226026422731.

• Problem with the join relationship condition master / detail

  Hello
  I need to join with master detail such as if there is no trace of the foreign key in detail to the primary master key, the foreign key must be attached to another column based on certain conditions in the master. For example:
  
  Control columns: pk1, rk1, rk2
  Detail of the columns: fk1, a, b, c
  
  I created a relationship with detail with the join condition, pk1 = fk1 in master.
  But according to value rk1, I actually join fk1 to rk2 in master and if the condition fails then join the pk1. I can't put this condition in the relationship that the form does not accept complex join conditions.
  
  I hope that my example has not confused everyone.
  
  Can someone help me to achieve this goal.
  
  TIA

  TIA,
  I agree with DM, rather than using the RELATIONSHIP between the blocks that I would create logic to manually set the DEFAULT_WHERE clause on the block of RETAIL with the criteria you need to MASTER block. This can be a little difficult if you want to form work the same way if you had defined a relationship because you will have to create all the triggers event coordination. The most difficult part is to choose the right triggers to coordinate the synchronization when a user accesses a folder of master to another. For just the basics (the block of retail is questioned when the user navigates to the retail block), you could do the following:
  1. create a When-new-folder-Instance trigger on the Master block to capture the relevant details to query the block detail and define the DEFAULT_WHERE.
  2 create a trigger in a times - news - block - Instance on the block of retail to run the query on the block of retail and display the details records.

  For example:

  /* Sample When-New-Record-Instance trigger */
  DECLARE
       v_temp_where          VARCHAR2(500); /* make larger if needed. */
  BEGIN
       IF ( :MASTER_BLOCK.First_Item IS NOT NULL ) THEN
            /* this is needed for when the user navigates to a NEW record in the MASTER Block. */
  
            /* Add your conditional logic here to determine how to build your WHERE clause */
            IF ( RK1 = 'Dependent Values' ) THEN
                 v_temp_where := 'PK1 = FK1';
            ELSE
                 v_temp_where := 'RK2 = FK1';
            END IF;
  
            Set_Block_Property('DETAIL_BLOCK',ONETIME_WHERE,v_temp_where);
            /* If you are using Forms 6i, the ONETIME_WHERE property is not available so you will have to */
            /* use the DEFAULT_WHERE property instead. */
       END IF;
  END;
  

  /* Sample When-New-Block-Instance trigger
  BEGIN
       /* This sample code assumes the user has not navigated to a New Record */
       /* so there will always be a NOT NULL default where assigned to the DETAIL BLOCK.*/
       Clear_Block(ASK_COMMIT); /* just in case the user made changes... */\
       Execute_Query;
  END;
  

  Please understand it is the EXAMPLE of Code and is intended to be a starting point for you - not the complete solution.

  I hope this helps.

• Page master detail problems

  Hi, using the tuning page Wizard master detail in DW MX and CF 7, I found a problem that I can't fix. The first page in the master page looks great, but when I use the 'next' button it display any records. I found that none of the paging buttons works to display the records. I was wondering if there was a known bug or problem with this page of assistant master-details.
  
  Here is my code:
