Passing field value to a jspx page

Question

Hi,
I am using JDeveloper 10.1.3.0.4 and JHeadstart 10.1.3.0.91.
We have a situation like:
Table: POSITION
Fields: POSITIONCONTROL_NO (PK)
BUSINESSUNIT_CD
EFF_DT
EXP_DT
BUDGETCAT_CD
Table: POSITIONBUDGET
Fields: POSITIONCONTROL_NO (PK)
FISCAL_YR (PK)
POSCAT_CD
EFTS_UNIT
TEACHING_UNITS
GL_OBJECT_OVERRIDE_CD
BUDGETCAT_CD
POSITIONBUDGET is a child table of POSITION.
When we create a record in POSITION, POSITIONCONTROL_NO is generated automatically from a seq no by a trigger in the database.
For POSITIONBUDGET we have a table-form layout. In POSITIONBUDGET_table.jspx page we put a button "New".
What this "New" button should do is:
1) It should go to a page (e.g. POSITION_insert.jspx) where we can create a record in POSITION table.
This new position record will have a seq-generated primary key in the POSITIONCONTROL_NO.
2) The next step is to proceed to the POSITIONBUDGET_insert.jspx where we can create a record in POSITIONBUDGET table
using the POSITIONCONTROL_NO field passed from .
table-form form form
POSITIONBUDGET_table.jspx --> POSITION_insert.jspx -> POSITIONBudget_insert.jspx
For (1) and (2), we created insert only pages (POSITION_insert.jspx, POSITIONBUDGET_insert.jspx) following the documentation you described in
JHeadstart Developers Guide, chapter 3 section "Build Insert Only Screens" which works individually. But we could not pass the newly generated POSITIONCONTROL_NO to POSITIONBudget_insert.jspx.
We know that we can create a link for POSITIONBUDGET under POSITION and create records from there.
Actually we have group like that already. But we want to have the functionality of the workflow shown above.
Could you please let us know:
In POSITION_insert.jspx, how can we redirect to POSITIONBUDGET_insert.jspx by clicking the "Save" button
which should also pass the newly generated POSITIONCONTROL_NO to POSITIONBUDGET_insert.jspx ?

This is not really JHeadstart related, rather ADF Business Components. But it seems to me that there are several things you can check:
If you run the ADF BC tester, and create a new Position row, is the generated PositionControlNo visible in the tester (after saving)? You might want to check out the DBSequence attribute type, described in the ADF Developer's Guide for Forms/4GL Developers (http://download.oracle.com/docs/html/B25947_01/toc.htm).
Then, in the tester, if you go to PositionBudget (as a child VO of Position), check if the foreign key attributes to Position are automatically filled in when you create a new PositionBudget. This could be a matter of defining the right ViewLink, and defining PositionBudget as a child of Position in the Application Module.
Other default values you want to be automatically created, can be coded in the create() method of the EntityImpl class.
Hope this helps,
