I have an 'Entity Reference' autocomplete field populated by a view that returns all authenticated user email addresses. I have set the field to 'Required' but when I enter an email address not in the list and save the node, it doesn't trigger an error. It just makes the field blank. Is there anything I can do to force the node not to save if a valid email address has not been entered?

  • You could add your own validation function to the form via a form_alter – 2pha Feb 22 '13 at 15:11
  • That would work. I was hoping for something a little simpler that doesn't require code. Thanks – user320691 Feb 22 '13 at 15:24

You should try changing the no results message in the view, maybe have return an invalid address like a@a@a.c or something.
