[jira] [Created] (ISIS-2253) Actions fail MM Validation when associated

Andi Huber created ISIS-2253:
--------------------------------

             Summary: Actions fail MM Validation when associated
                 Key: ISIS-2253
                 URL: https://issues.apache.org/jira/browse/ISIS-2253
             Project: Isis
          Issue Type: Bug
          Components: Core, Core: Viewer: Wicket
            Reporter: Andi Huber
            Assignee: Andi Huber
             Fix For: 2.0.0


In fact, this is a case of two wrongs not quite making a right. There's a nasty hack in that it is the Wicket viewer that knows how to populate the choices for the parameter, and it does this without looking for an autoComplete or choices facet ; it just picks up the checked items of the associated collection.


 The short term solution to fix DemoApp is just to update that metamodel validator to also take into account any AssociatedWithFacet.


 The long term "correct" solution is a new facet factory that will derive a ChoicesFacet from the AssociatedWithFacet, and then to remove the special case logic from the Wicket viewer.

That would then make the validator correct as it is now written.
