From some reason the Child fields are disabled on Add mode, but are fine in Edit mode. Somehow before it worked fine.  In the Child object the IncludeInFormAdd is True and in the form level the IncludeInFormAddType is DetermainedByBusinessObject. This is just an exercise for me to learn the SF, but the child and the parent should be saved at the same time. Using SF 1.6.5.1

Thanks,
