My form checks if a username exists in the database.
Database field: username has a unique index
I'm using the Validate Data step in Server Connect
I've set up a Responsive Notify behavior for the onDataValidationError event for the Insert Record executor under Options
The username does not get overwritten if duplicated, but I don't get a Notify message.

I now see that the behavior panel does not save this particular behavior/event.
No problem with saving an onError event - just a problem with onDataValidationError

Any suggestions please?
