---------------------------------

             Summary: Invoking an action button which was rendered enabled but 
which is actually disabled at point of invocation throws stacktrace.
                 Key: ISIS-1730
                 URL: https://issues.apache.org/jira/browse/ISIS-1730
             Project: Isis
          Issue Type: Bug
          Components: Core: Viewer: Wicket
    Affects Versions: 1.15.0
            Reporter: Dan Haywood
            Priority: Minor
             Fix For: 1.16.0


For example, if the domain object is rendered and then some other user changes 
its state such that an action is no longer available.

The framework *does* correctly re-check the state of the action, but if now 
found to be disabled then we get a stack trace rather than - say - a toast 
pop-up with the reason that the action can no longer be invoked.
