Hello all,
I've added a link to "Folder" within my custom schema "Theme":

At the same time I have an input form for the creation / editing of records of "Theme" schema and I would like to set the folder id automatically (as done in native "Recipient" and "Service" forms).

As per my tests, I receive the error shown above: "The folder is not specified".
Could you tell me what I'm missing?

Thank you,
Salvatore
