Issue with Master Detail relation in OAF page -- Help

Hi,
I am developing an OA page with a master detail relation. The detail records are displayed in the subtab region.
The issue that I am facing is as follows:
If there are 2 detail records in the detail table, then my page is displaying these 2 records twice i.e.
Detail Records:
Header Id Line Id
2 1
3 1
Header Id Line Id
2 1
3 1
If the number of detail record increases, then again the display also increases that many times i.e. 3 records gets displayed thrice.
Kindly help to figure out the issue.
Thanks In Advance.

Hi,
Take the following actions.
1. Try to display your records in simple Table and remove it from subtab,
2. check relations as well, you can delete and re-create all the relations with EOs and VOs and recreate them.
3. Also check when your VO get popluated that how many rows are there in Detail VO ?
For example.
int x = yourViewObject.getRowCount();
System.out.println("Number of rows in detail view Object"+x);

Issue with Master Detail OAF Page

Hi Friends,
I have an issue with the Master-Detaiil Page.
I have developed a Master-detail form in OAF similar to the one in Oracle Forms. The master details are appearing fine. I have created a transient variable selectFlag that represents if the master record is selected. I am also able to see the detailed records after I have written the code in CO to populate the details table when a master is chosen.
But in the detail table I am seeing all the records. I should be able to see only the records that are children for the master record.
I have created the ViewLink as well. How can I pass the id of the master record to the detail table.
Any ideas. Kindly help.
Thanks

Hi,
Are u using partialAction on master form for this ?
You can add parameters from property inspector and put some unique attribute from VO and later filter the details record based on that.

Problem with Master -Details forms in seperate pages

Hi ,
Below is the scenario:
I have Institution and a department tables where there is a foreign key relation between the tables. So now i have two entity objects for the 2 tables and 2 view objects(DepartmentView,InstitutionView) from the entity objects.
I also have a view link between them.I made a master-detail relation between them in the datamodel using the view link.So my appmodule now has getters for the department view,institution view and viewlink.
I now have a jsp page "createInstitution.jsp" which contains a form for the institution , i have a "next" button on the same jsp which calls a method in my appmodule class .This methods just inserts the record into the Institution view. In this method i am able to see what the user entered in the form by getting the viewrow record like the below code :
InstitutionViewRowImpl newInstitutionRow=(InstitutionViewRowImpl) getInstitutionView().first();
The next button navigates to the next page "listDepartments.jsp" which contains the list of departments that are added. This page has a button "Add Department" which takes to to the "addDepartment.jsp" page which shows a form for adding a department. This page also has a button which calls a method in app module class. The method just inserts the record into the view(DepartmentView)
Here when i say
DepartmentViewRowImpl newDepartmentRow=(DepartmentViewRowImpl ) getDepartmentView().first();
the newDepartmentRow is null.
Also on the addDepartment.jsp form , i had used a output field to see what the parent id was and interestingly the parent id is 75 which is first institution in the database. It should have been "-10" , a temporary id assigned.
Can someone please tell me what is the problem with my approach?

I don't understand why you are using a method on your button to insert the record into the table - An Oracle ADF Form will do the insert for you by default without any coding.
See the create pages in these tutorials:
http://www.oracle.com/technology/products/jdev/11/cuecards/adf_set_21/ccset21_ALL.html
http://www.oracle.com/technology/obe/obe11jdev/11/dev_ui/developuserinterface.html#t2s5
The method that you are calling just returns the first record in the rowset - I don't see how it has anything to do with actually inserting the data into the table.

Issue with messagedownload field on custom OAF page

We have a custom OAF page where we are displaying file attachments using messagedownload field.
We have a VO for this field where we are fetching the file name and file (BLOB).
For the message download field, the properties are set as:
DataType: VARCHAR2
View Instance: custom vo
View attribute: filename
File View Attribute: filedata(BLOB column)
The issue is when we have multiple files to display of the same file type like 6 pdf files, the file name is correct, but the content is correct only for the first file. The remaining 5 files also show the content of the first file though the filename is correct.
Please let us know if anyone faced similar issue and the probable solution.
Thanks in advance.
Regards,
Kiranmayi.

Check that the view object used to render the table must have a designated primary key, else download bean will download content from the first row every time.

Master-Details Relation

Hi All,
I Have one dought,I have a form with master-detail relation.
If i query in header level i can able to see all the data in both levels.
If i query in detail level i cannot see header level information,but i can able to see the detail level only.
Can any help me in this
Regards
Siva

Remove join condition and relation as well! In master block you should have in where close "database_item = :bl_2.item" and in detail block you should have where close with "database_item = :bl_1.item". When user put the cursor in bl_1 and execute query the bl_2 should be listed as well. You can do this on different way for ex.: write in key-exeqry or when-new-record-instance etc. on bl_1 go_block('bl_2'); execute_query; And inversely or "vice versa": when user put the cursor in bl_2 and execute query the bl_1 should be listed as well. You can do this on the same way for ex.: write in key-exeqry on bl_2 go_block('bl_1'); execute_query;
If you want to create record you have to be carefuly on the key items in both blocks. So you have to fill the key item before user want to do the commit form. That's all but I did not test it so I can not know how could both where condition behave with different users action.

Serious problem with previous / next record in master-details relations

I have master-details relations like this (if master is A) :
A-B
A-C and C-D
When I move down with do_key('next_record') all values of all records in all blocks are OK. But when I move up, it doesn't work : all D block values are erased and I don't understand why ?
Thank you for your help.
Antoine LEFEBVRE.

Blocks A and B are in the first canvas and blocks C et D are in the second canvas.
On next_record action from A the B is updated, C too and D too. But on previous_record action, D is not updates.
To display the second canvas I use a command button and into the WBP trigger there is :
go_block(C);
execute_query;
to be sure to execute query, but it's null.
What's your suggest ?
Thank you,
Antoine.

Populate PK(DBSequence) in three related tables with master detail association

Hi
I use jdeveloper 11.1.1.6.0.
My English isn't very good.
I have 3 tables with master detail association between them and primary key from table A should populate to tables B and finally C .The primary key is a sequence from data base and I set PK attribute in table A as a DBSequence. (table C is the child of table B and table B is the child of table A)
My association is like this: A->B(BAFk1Assoc) and B ->C(CBFk1Assoc) and also I select Composition Association for these two association. And I select ‘Cascade Update Key Attribute’
When I insert row in these three related tables, a negative number create but when I COMMIT the PK populate only to table B not to table C and the exception below raises:
Constraint "C_B_FK1" is violated during post operation "Insert"
ORA-02291: integrity constraint (HR.C_B_FK1) violated - parent key not found.
If I only work with tables A and B, there isn't any problem but if I add table C as the child of B, this exception raises.
Habib

The question is how you create the row for table C. Do you create it as child from table b (using the VO for B and using the link to C)?
In this case the framework should populate the PK of the master row B as FK in table C.
You may need to control the order in which the rows are posted to the DB to avoid this problem. Read Advanced Entity Object Techniques - 11g Release 1 (11.1.1.6.0) to get more info about this.
However, sometimes it's easier to control the generation and setting if the PK attributes in the model layer, not relating on db triggers where you get the real values only after the commit operation is done in the db. For this you can use a Groovy expression so you have access to the PK of each new created row right after creation. Read Using Groovy Expression to set a Primary Key with a Sequence Number | JDev &amp; ADF Goodies to find out how to do this.

Issue with File Download(messageDownload) on Search Page.

Hi,
I created a custom OAF search page which fetches values from one table. The document in getting stored in my custom table in a BLOB colums and NOT in FND_LOBS.
The table has 3 collumns along with others:
1st is primary key (Record_Seq) ==> number data type
2nd to store actual file name (File1Name) ==> varcahar2 data type
3rd to store the actual uploaded data (File1Data) ==> BLOB data type
The reason for having the “File1Name” is so that I can display the original file name of the document that was uploaded, instead of just the “view” in the search page results .
On the File1Data BLOB and created a messageDownload for that under query results table with following details:
ID : File1Data
ItemStyle : messageDownload
FileMIME Type : pdf
Datatype : BLOB
View Instance : LacEmpExposureVO1
view Attribute : File1Name
File View Attribute : File1Data
When I click on the "File1Name" data hyperlink, it is opening only the first document corresponding to the first record in the search page results.
For example, If my search page returns 10 rows then when I click on the file1name on any row, It is open the first row file name only.
I have a primary key column(RECORD_SEQ) in the Table / EO / VO which is displayed in the search page results.
Also one weird thing is happening:
If I try to do this more than 2 times then it is opening the update page with the first record from the search page results…
I tried to print the context and it is nul the first time, But the second time then context is changing to "update". Dont know how this is happening????
Any advice is greatly appreciated as it is very crucial for me to get this resolved ASAP. I have looked at several forums and did a lot of things as advised in the forums . But nothing seems to work for me.
Thanks,
Mir

About master detail relation ship between tables

Hi
I am using jdev 11.1.1.5.0
Use case:
I have 2 table having master-detail relationship
master table - req_hdr
detail table - req_file
req_hdr is drop as adf table (t1) on a fragment page and req_file is drop on popup as adf table (t2).
user can add any no of row in req_file with respect to each row of req_hdr.
to open popup for req_file, a command image link is provided in one column of req_hdr.
On popup, there is two button provided for save and close.
On save button,commit operation is performed and on close button,rollback operation and popup.hide() is performed.
Now the problem what I am facing is
1. If with respect to any row of req_hdr there is one row already exist in req_file and user click on add button to add new row in req_file and randomly user decide to to close the popup rollback operation is performed and again when user click on same row to open popup.
Popup contains no row while in database there is one row exist for that.
2. if user add a new row in req_file and perform save( commit ) and again for next row of req_hdr user open a popup to add new row in req_file and click on add button ,values of preceding row is already populated in new row while is should be empty because req_hdr and req_file have master detail relation and for next id of req_hdr, req_file should display new row.
Anyone have the solution regarding this....?
Thanks..

the contentDelivery for the popup is already set to lazyUncached
and on add button i use following code to add new row:--
<code>
Row r_file=null;
CollectionModel tableModel = (CollectionModel)getT2().getValue();
JUCtrlHierBinding adfModel = (JUCtrlHierBinding)tableModel.getWrappedData();
DCIteratorBinding dciter = adfModel.getDCIteratorBinding();
NavigatableRowIterator nav=dciter.getNavigatableRowIterator();
r_file=nav.createRow();
r_file.setNewRowState(Row.STATUS_INITIALIZED);
Row lastRow=nav.last();
int r_index=nav.getRangeIndexOf(lastRow);
nav.insertRowAtRangeIndex(r_index+1, r_file);
dciter.setCurrentRowWithKey(r_file.getKey().toStringFormat(true));
r_file.setAttribute("Sno", vo_file.getEstimatedRowCount());
r_file.setAttribute("Filetype", null);
r_file.setAttribute("Filename", null);
r_file.setAttribute("Remark", null);
</code>
There is any help regarding this....?

Actually one table was there at that time it worked but with relation it creates problem.
Can anybody give me any idea how to sort out this problem.

Helo Frankin
Actualy the error came when i made the master detail relation manualy.but as per me if both tables have relationship with each other then no need to create it manualy isn't it?

Master-Detail Relation- Detail records not displaying

Hi All,
I am working forms(10g) customization for an oracle applications. our requirement is to develop a new window(screen) which should display all the related child records for the master record in the main form on a button press.
i have developed a new database block based on a vew and provided the relation with master block, and done the required customization.
But, when i run the form, and clicked on button, it is giving an error
FRM-40350 Query caused no records to be retrieved.below is the code that i have written on button click
BEGIN
          IF event = 'WHEN-BUTTON-PRESSED'
          THEN
          SHOW_VIEW('XXSCP_GBL_CUST_PEGGING_CON');

Creating a master-detail relation between a view and a table

Hi all,
I have a problem with creating a master-detail relation between a database-view with lots of customer data and a small table with per customer a list of entities of our companies who may work for that customer.
Somehow I seem to be unable to create a relation between these two. I can't find where I can make a foreign key using Toplink to implement the relationship. And neither can I get a Viewlink object doing the job using ADF Business Components.
Somebody any suggestions on this problems?
Regards,
Birgit

There is a key relationship between two fields which form the primary key in the main table of the view and two fields in the second table.
I created a viewlink manually, but I still couldn't get the data correct i.e. a form with one record of a customer from the main view and a small table with all entities of our company who can make performances for that customer.
I tried to find a manual or a how-to on this topic but I didn't find anything helpfull yet.
Regards,
Birgit
After a couple more tries, I got the master-detail working. With all the fiddling I am not sure what caused the problem but I think the finally action was checking which fields of the view were marked as primary keys.
Now everthing is up and running.

Master Detail on the same page PHP - MySQL

Hi,
Is it possible to create a page using spry master region and call MySQL data into a Spry detail region, like you do with xml data?
Basically, is there a way to have master detail regions on the same page without using frames?
Thanks
Bert

Thanks for that, very useful indeed.
But isn't it going to be slow, first transferring the MySQL data to XML then reading XML to display the records.
What is the advantage other then displaying master detail on the same page?
Thanks
Bert

Need Master-Detail relation to link Master column to 2 different detail col

I have a form with a master detail relation. The master block is a database table rec_shipments with a primary key of shipment_id and a bunch of other columns. The detail block is a table rec_containers with a container_id as the primary key plus column shipment_id, split_shipment_id, weight, volume, etc. The shipment_id and split_shipment_id are nullable.
When a shipment is received a shipment record is created and container records are created with the shipment_id populated and the split_shipment_id null. In the form a relation was created between the shipment block and the container block as shipment_id=shipment_id. This works fine. However, they have the ability to spit the original containers into smaller more manageable containers for distribution. For example if they receive a railroad car full of pallets of printer paper they may take and divide them, half into 1 rolloff bin and half into another rolloff bin. The rolloff bins will get a unique container_id for tracking. The record in the system created in the rec_containers table will have the split_shipment_id populated and the shipment_id null. In the screen they want to see the original containers (railroad car) and the split containers (rolloff bins) when the query the shipment.
What they want:
Shipment_id -- and additional information
Railroad Car ID plus additional information
Rolloff Bin 1 ID plus additional information
Rolloff Bin 2 ID plus additional information
My problem is the rolloff bins don't show up with the current relation because the shipment_id is null in the 2 rolloff bin records.
I've tried creating a view on the rec_containers table that is all the columns in the table plus 1 additional column that is
nvl(shipment_id,split_shipment_id) comp_ship_id
and set the relation to shipment_id=comp_shipment_id. I set the comp_shipment_id column to query yes and insert & update to no because I don't want to update that column in the view.
The problem is I can't update any columns, I get a can't reserve record for update or delete error.
Does anyone have any ideas how I can get the containers block to query all records where the shipment_id or split_shipment_id matches the shipment 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. In order to make the block updateable, you have to sst the property "Query only" for your derived item to "Yes". Witn this, the column will not be included in any further dml. About the locking... it may be that forms isn't anymore able to do proper locking when a block is based on a view. In that case, put an ON-LOCK-trigger on the block and lock the record by yourself doing y SELECT FOR UPDATE NOWAIT on the record. To just try if this would work you use a NULL in the ON-LOCK just to xheck if the dml-operations itself will work. if your view is based on only one table you have good chances that there is nothing to change, if you get an error like "View not updateable", you have to do some further adjustments
-Set the key-Mode for the block to "Non-updateable"
-Set the property "Primary key" to "Yes" for the pk-item in your block.
hope this helps
