Hey mate,
I got around that specific validator, however the is_in_set validator
causes the problem. (It’s needed to create the select field in HTML)
I managed to get around it with onvalidation, doing the validation based on
a state of the control but this is adding more logic on the backend and
takes away from the model functionality.
Regards,
James
