Error creating Master/Detail Form

Hi,
I tried to create a master detail form. I went through all the steps fine, only when i click the button to create the form, i received the following errors:
ORA-20001: Unable to create master detail page. ORA-06502: PL/SQL: numeric or value error: character to number conversion error
Unable to create Master Detail pages.
Could someone please tell me what's wrong?
Thanks,
Patrick.

We are getting this message in several areas in the development environmnet. It's happening in the developer login screen, when creating new tabs, and when tryig to create master detail reports. Here is our error from the Apache Log:
[Mon Mar 2 11:41:31 2009] [error] [client 10.64.8.231] [ecid: 1236012090:148.94.143.136:24226:0:1621,0] mod_plsql: /pls/apex_qmnt/wwv_flow.accept HTTP-404 ORA-06502: PL/SQL: numeric or value error\nORA-06512: at line 31\n
I think this is different from the issue above as that is due to too many items in a shuttle list. Ours seems to be related to our new APEX insstallation. Any help is appreciated here.

Problem in Master Detail form

Hello I am new to Form Developer and the question I am asking may be very simple for experienced programmers but as I said I am new to forms development so I am finding it a bit hard.
I have got the following three tables in database.
1. Student (roll_no, name) Primary key is roll_no
2. Fee_type(Fee_code, Type, Amount) Primary key is Fee_code
3. Fee_Receipt(roll_no, Fee_code, Date_of_Payment) roll_no & fee_code are foreign keys
I want a form containing a combo box filled with all the roll numbers of students, a combo box containing all the fee types and then fields for entering data into fee_receipt table by using text items.
I dont want to see the names of students, just their roll numbers filled in the combo box. I dont want to see the fee code i just want to see the fee types in the second combo box.
how would i be able to do that. Any sort of help big or small will be appreciated. Thanks in advance

Master detail form issue

Hello,
I am unsure if this is a bug or how I'm doing things. I'm using version 4.1.
I am creating a master/detail report (on the same page) using the wizard to create the page. I have no problem creating the page and it works. The only changes I make to the detail region (which is a report) is to set it to display one record at a time, enable partial page refresh and change the layout to a vertical list including null columns. Essentially I want to see one record at a time. I can certainly page through them one at a time. However if I press "Add Row" it creates a new blank record below my existing one. If I keep pressing "Add row" I keep getting more blank rows. Shouldn't this blank row overwrite the currently displayed row so that there is only one row at any given time (whether its blank or a populated line). If I'm saying I only want one shouldn't it only ever display just one record regardless of whether your adding or reviewing existing detail records. It seems to me that if I tell it I only want one row, it shouldn't allow me to keep adding rows indefinitely which end up getting added to rows already on the screen. On a vertical listing with a lot of fields, you could end up scrolling for days.

Hi -
My assumptions are:
1) That you have created Master/Detail form with both Master and Detail regions on the same page.
2) The problem of NOT seeing the Detail happens when you are inserting (not updating) on Master,
in other words when you are creating a new user in Master section.
The Detail section (as created by Apex Master/Detail wizard) is a Report with a Condition set for display:
"Value of Item in Expression 1 Is Not Null" with Expression 1 populated with PK of Master.
So, change this condition to None and empty Detail section will appear in Create mode.
Note that you must now set the Form object that holds the PK for new Master record by some means,
(maybe a Page Process or such) before the Save is done, otherwise Detail record will not have FK.
Also you are going to have to play with the Conditions on the ApplyMRU and ApplyMRD Processes created
by the wizard to make sure they are only firing in Create mode when the Save for the whole page is submitted.
Lastly you can clear the values on the page with a Process of type "Clear Cache for all Items on Pages" that fires
last after page submission, again this may need a Condition to prevent clearing items before you are ready...

Problem in Master Detail form when using ADF table for Detail

hi,
jdev version-11.1.2.1.0
i have create Master detail form using datacontrol drag as ADF Master Form Detail Table.
Now when i create a new row in Detail table using CreateInsert button a blank new row created on the top of detail table.
and other row show that data of previous record based on master.
problem is that i want when i click on createInsert button all row of detail table should be blank and when user fill two or three row then commit.
Thanks in Advance

Hi,
if a detail table has data, then createInsert adds to these. If you want to hide existing rows, create a new View Object instance and set its "Retrieve from the Database" option to "No Rows". The use an af:switcher to change the table shown when the user clicks the createInsert button. There is a bit of coding required to have this use case in ADF, but its mostly declarative. Bottom line is that there is no automated option other than creating new rows in a separate page or dialog if you are bothered by existing rows

Can't put Combobox in Master-Detail Form

I'm trying to create Master-Detail form with LOV's, but in both the Master and Detail selection, the Item Type LOV doesn't include combobox.
From the looking at some of the Posts, this seems to be possible.
Does anyone know what I need to do?
Thanks Larry

Hi,
This is because you do not have any LOVs defined in your application. This LOV will show the LOV types, only if the application contains any LOVs. Define a LOV and then edit the form. You will be able to see it.
Thanks,
Sharmila

Master details form in Oracle BPM

Hi All,
Could anybody please let me know if we can create master details form in Oracle BPM too? If yes kindly help me in this regard. Thanks
Regards
Nasir

Hi,
I tested it on JDev12c and also works:
Couple of tips:
- Try to keep your payload as small as possible. Check this post: http://avioconsulting.com/blog/decoupling-oracle-bpm-process-instance-information If you put all your information on XML is like you have two databases and is annoying to keep them sync.
- if you decouple your data, you will be able your UIs, so you could create an ADF app with bounded taskflows (e.g.: Master-Detail) and embed it on your ADF-HumanTask app.
Hope this helps,
Jorge

How to Create a ADF Form same like in Oracle Forms

Hi,
I need to create a Form in ADF where in on the top I have two text fields with LOV and one Text with out LOV and a button. Selecting values from the first two should populate the value of thid text
and pressing the button should actually populate the fields below.
Below I have several other fileds of which few are queried from the database and other are calculated fields (aka like control fields in Oracle Forms).
Now I am a Forms Developer and know quite a few things in ADF as well, like creating Master Details Forms and some of the work flows. Some basic functionaliy.
I want to make an attempt to create something like this which is created in Oracle Forms.
What I have tried as of now is create a query and added LOV to first Text. Displayed all the fields as ADF form and on top I have put a ADF Query panel , using this I am able to populate few of the columns.
Can someone tell me what is the best way to do the things which I have mentioned.
TIA

Hi,
If your need is to auto populate other employee fields of the page based on previous 2/3 fields like deptno, empno, loc, then you can achieve this with button action listener. You can add runtime bind variables to your view object and set them with user input values and execute query.
for e.g, you can add below code in your AMImpl class and expose it to UI and invoke it from UI (from page, create a managed bean and call AM method)
/***** Sample code only*****/
public void refreshVO(Integer EmployeeNo, Integer DeptNo, Integer locNo)
ViewObject vo = this.getEmployeeVO();
vo.setWhereClause(null);
vo.setWhereClauseParams(null);
//Adding empNO where clause
vo.setWhereClause("employeeno = :empNum);
vo.defineNamedWhereClauseParam("empNum", null, null);
vo.setNamedWhereClauseParam("empNum", EmployeeNo);
// similarly add logic for DeptNo, LocNo and you can additional check if they are null or not null
vo.executeQuery();
