None of my sections in any of my forms are bound to fields, as far as I can tell. Rather they are bound to the group ....RW. They are the same in the good forms and the bad one. I think I was adding or changing something in the section on the bad form too fast or with an error, that is now fixed, but the error elf doesn't forget.
If I create new sections to use, bound to fields, does it matter if it is a field that will be on a control inside the section? Or just a random field that will not be in the section? Would a new idle field be best?
