IT WORKS!!!!!!!! AHHH SUCH A RELIEF!
Thans a lot, guys, you made me see the problem I was having, so I set up the
Set Content binding of the ItemXInvoice Array controller to be
_newInvoice.toItemsXInvoice properly set the relation in the add and
addPredifiened methods, and it did work!.
OMG 5 days trying to solve this and finally its done.. thanks a lot once again
Gustavo.
PS, I have remove the things that seem and were really wrong, as Ben told me.
