The form is created correctly. No error occurs.

you put that ID in the where clause of SQL settings?
for that form application, pro_teilprojekt_frm, what do you have for “where clause”?
is it something like:
Yes. Have a look at above.

There’s a misunderstanding. I’m talking about blank app.
I don’t think the issue is with a blank application.
Hi, if I do this like this, form is empty an no error occurs
you said form is empty, and pretty sure you’re referring to “pro_teilprojekt_frm”. Is that not a form application?
I’m basically suggesting that you’re passing the id to this form application but the form application isn’t set up to do anything with that id, I speculate that’s the reason why it’s empty.
