Hi grigri
The way I thought of is assign any Behaviour validationErrors to a
controller instance of that particular model (via a model-
>getBehaviourErrors() method) - but it sorta defeats the idea of
having a behaviour acting at the model level... hence the question -
the implementation seems a bit kludgy, even though the two-model
concept 'feels' right.
