ZF-3242: Add functionality to set form-level errors
As discussed on fw-mvc, it would be nice to be able to set form-level errors that apply to a form submission as a whole and not to any particular element. This could be useful for, e.g., 'Invalid login credentials' or 'there was an error submitting your form'.
I have outlined a possible solution at http://codecaine.co.za/blog/posts/….
I think that the code should operate at the Zend_Form level and not at the Zend_Form_Element level.
