Don't process textareas with #access = false

Issue Summary

Hi there,

I'm not sure if this belongs in the Form API issues queue or the FCKEditor queue. Here's the issue:

I have a form field that I hide from certain users by altering the #access value of the field in hook_form_alter(). While this hides the input just fine, the input is still processed through fckeditor_process_textarea(), which adds a bit of javascript. When the field is not present, the javascript causes an error (something like 'oFCKeditor_edit_body is not defined').

It doesn't look like it's possible to hook into this to prevent the javascript from being placed in the HTML - form_builder() first sets the field's #processed value to FALSE (so changing that in hook_form_alter() doesn't help), and then it runs the #process functions regardless of whether #access is set to FALSE or not.

So I think either fckeditor_process_textarea() should check whether the field has !(#access == FALSE), or form_builder() should not #process a field unless !(#access == FALSE) - but the form_builder() function might do this on purpose.

Thank you!
