OAF Parameterized Popup Issue (12.1.3)

Question

I am unable to access the parameters set by the parameterized popup within the base page PR method.  The popup page controller PR method has no problem accessing the parameters but I need to access them in the base page controller PR method as I believe the popup documentation says is possible.  I've read everything I could find on this and I believe I have tried everything.  But the base page PR method gets null for the pageContext.getParameter("popupEvent") call when it is invoked after the popup is submitted.
I am trying to use the popup as an LOV for a detail table since LOVs are not supported in detail tables.  And everything works except for the the base page PR method.
Please help.
Thank you

It's all working except for the saving of the detail VO changes I make in the base page controller's PR method.  I can see the changes reflected in the rendered page but the changes don ot get saved to the database.
XxmclApValidatorSetRevsVOImpl vo1 = (XxmclApValidatorSetRevsVOImpl)am.getXxmclApValidatorSetRevsVO1();
XxmclApValidatorSetRevsVORowImpl row1 = (XxmclApValidatorSetRevsVORowImpl)vo1.getFirstFilteredRow("RevisionNumber",new Number(1));
RowIterator rulesIterator = row1.getXxmclApValidatorSetRevRulesVO();
while (rulesIterator.hasNext()) {
  XxmclApValidatorSetRevRulesVORowImpl row2 = (XxmclApValidatorSetRevRulesVORowImpl)rulesIterator.next();
  row2.setOperator1(operator);
I can use the master VO object to update master VO attributes in the base page controller's PR method that do get updated to the database.  So I believe it's a problem with the detail VO.  Perhaps I need to call a method to tell the AM that the detail VO needs to be saved to the database.  Any ideas?
Thank you
