Help! Error 22. Invalid Operation

Hi everybody.

I have a form and after save it (keeping to fill the required fields) appeared this message: Error 22. Invalid Operation.

If someone had that experience please, help me to undestand what must I do?

Sorry for my poor English.


Hi, I have resolved this. The problem was in the numeric field of Postgresql. In the _form.php I’ ve included the rule default 0 and it works.
