#35 Why shouldn't a child form return errors?

[Jean Jordaan]

In PlominoForm.createDocument I see::

errors=self.validateInputs(REQUEST)
if len(errors)>0:
if is_childform:
return """<script>alert('erreur');</script>"""
return self.notifyErrors(errors)

Couldn't the is_childform clause also return 'errors'?
