I just stumbled over an older Notes Designer bug after a long time not developing native notes applications:
To make my live easy i tried to copy / paste a subform from one form into another, saved it…boom… The form got corrupt with the friendly message “Not a Form”…
Is there still now way to recover the Form? This would mean that i wasted my whole day so far…
Subject: No i copied the subform from another form…
I copied it from another form and i was sure that there was not the same subform already in the form, however maybe i pressed ctrl-v twice… but when i saved the form there was no error message… The Subform itself is very simple (2 tables, 4 fields, no actions or other subforms)…
I tried editing with DXL, but as soon i edit the DXL, it seems that all the stuff after the subform is being removed… after saving and reopening the form the form is blank…
I tried also access the form with an agent and remove the Subform Items, but no success…
Well i’ve given up, started again with the form… luckily i could access the form title, form events and actions from DXL…
Unfortunately, i can’t remember which subform it was… I had also other selfproduced issues in the database when i changed some arrangements of the subforms / fields (double names fields in form / subform, design element inheritance). So i think it’s a mix of many things which resulted in this error…
Subject: Did you have that subform already in the form?
You can’t have the same Subform in a form more then once. If it is not a computed subform it should warn you and not allow you to paste (IIRC). However if you have a Subform within a subform it might not pick up on this.
Eg.
SubForm1
SubForm2 = Contains SubForm1
Form = Put on Subform1 and SubForm2 and save. Error will now happen.
Are you able to open the form with the “Edit as DXL” option? Or modify the subforms to a blank one (rename and create a blank one).
