> Derive ChoicesFacet from AssociatedWithFacet, remove special-case logic.

> Key: ISIS-2253
> URL: https://issues.apache.org/jira/browse/ISIS-2253
> Project: Isis
> Issue Type: Bug
> Components: Isis Viewer Wicket
> Reporter: Andi Huber
> Priority: Major
>
> 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.
