These changes were necessary in order to allow transactions to work
properly. The fact that your forms were working before simply meant
that you were not using explicit transactions. Also, it is more than
likely that with implicit transactions, you could get non-ACID
commits; IOW, the parent would save and commit, but then the child
save could fail, leaving you with an incomplete transaction that you
would have no way to roll back from.
I'm sorry that this is slowing you down, but it is necessary if we
want to ensure data integrity.
