I'm missing something. I've written a plugin to manipulate specific custom user fields (the new custom fields extension). I create the fields, and make them required, but in /adminstrator I remove the required attribute using:
$form->setFieldAttribute('fieldname','required','','com_fields');
That part works great.
In my plugin, I also identify groups which will be relieved of the requirement in the frontend - but none of those attribute changes seem to stick.
If I print_r the $form variable before and after I make my change - I can see the change is made in the JFormXML object - but the form still displays the field as required. I can add a class attribute and it shows up in the backend - but not the frontend.
I even went so far as to execute $form->removeField('fieldname','com_fields') and to my surprise, the field re-appeared at the bottom of the field group (from first to last)! There seems to be no way to modify these fields in the front-end....unless I'm missing something.
