Create detail rows programmatically

Question

I'm using jsf/adf bc. I have a situation in which when my jsp is rendered, it displays inputs for each row of a master/detail/detail arrangement. Each level is connected via a view link. So, before the page is rendered, in my app module class, i'm trying to do the create/insert of each row, in the order they need to be created. This is basically how i'm doing it.
ViewObject masterVO = getMasterVO();
Row masterRow = masterVO .createRow();
masterVO .insertRow(masterRow);
ViewObject detail1VO = getDetail1VO();
Row detail1Row = detail1VO.createRow();
detail1VO.insertRow(detail1Row);
ViewObject detail2VO = getDetail2VO();
Row detail2Row = detail2VO.createRow();
detail2VO.insertRow(detail2Row);
when the page is rendered, i see inputs for fields of all vo 3 rows. however, when i enter valid values for these fields, i get an error which basically is telling me that i haven't entered in values for the detail2 vo row. It's almost as if the 3rd vo row that's displaying on the page is not the row that was created programmatically, if that makes any sense. If i comment out the code to create the 3rd vo row, and just create new master and detail records, things work fine. What do i need to do to create/insert new vo rows for all 3 levels?

Answer 1

thx for the suggestion john. i tried that approach, but now get a slightly different error: JBO-25030: Failed to find or invalidate owning entity:
Apparently, for the last level detail record created, it's parent cannot be found. Again, when the page renders, i see empty input fields for each row that i've programmatically created, but committing the transaction after entering valid values causes problems...It's as if the new rows that are being displayed aren't really associated with each other, when they should be.
