In one form, the required is not working for any fields. In another form, it works. When I set a field to "required", then try to save or submit the form with nothing in the required field, an error occurs (error in the front end and backend forms):
I figured out what happened. One of the fields, a select dynamic cascade field, was causing the problem. If I took out the field of the form, the required worked. I think I setup the field wrong and I only needed to use a Joomla! Article field anyways.
