Form Fields Disappear

Still on evaluation version. Had this happen twice now. I take a form that is working fine and just changed a block from beside to below. Save it. Go to run and it comes up with error “Form Fields Undefined.” If I look at my field listing, sure enough, they are totally gone. I can’t imagine what I would have done to cause this. The tables are synchronized, the sql statement correct, the blocks and field positions all good…but the field list is totally empty. What gives?

More info. I discovered it totally removes everything from the shown blocks and entire layout needs to be reconstituted for the field list to appear. Surely this isn’t normal behavior.

Did you ever find a fix? Mine is doing that as well.

I haven’t had it happen in a while, but no idea what caused it…what causes it…and how to prevent it!

Ya I just deleted the labels on my Control form and re-inserted them… problem went away
