Dan Haywood created ISIS-497:
--------------------------------

             Summary: Allow service actions to be rendered as contributed 
collections or as contributed properties.
                 Key: ISIS-497
                 URL: https://issues.apache.org/jira/browse/ISIS-497
             Project: Isis
          Issue Type: New Feature
          Components: Core, Viewer: Wicket
    Affects Versions: core-1.2.0, viewer-wicket-1.2.0
            Reporter: Dan Haywood
            Assignee: Dan Haywood
             Fix For: viewer-wicket-1.3.0, core-1.3.0


Thus:

a non-void service action that accepts a single argument of the entity type is 
rendered as a property if it returns a scalar, or a collection if it returns a 
list<T>.

To prevent the service action from being contributed, use @NotContributed 
annotation, which is extended to:

@NotContributed  ... not contributed at all
@NotContributed(As.ACTION)   .... but is contributed as a property/collection 
(dependent on return type)
@NoContributed(As.ASSOCIATION) .... but is contributed as an action

Contributed collections are implicitly eagerly rendered.
Contributed properties can be hidden from tables by annotating the service 
action with @Hidden(where=ALL_TABLES), in the usual fashion.
