             Summary: Extend Isis metamodel and Wicket viewer so that a "delete" action can be automatically provided for deleteable objects.
                 Key: ISIS-992
                 URL: https://issues.apache.org/jira/browse/ISIS-992
             Project: Isis
          Issue Type: New Feature
          Components: Core, Viewer: Wicket
    Affects Versions: core-1.7.0, viewer-wicket-1.7.0
            Reporter: Dan Haywood
            Assignee: Dan Haywood
             Fix For: viewer-wicket-2.0.0, core-2.0.0


per [1], 

@DomainObject(
   deleteable=true
   ...
)
public class MyClass { .. }

could be used to automatically generate a delete() action:

public void delete(Entity entity) {
  this.getContainer().remove(entity);
  this.getContainer().flush();
}

~~~~
However, there are some things that need to be thought through here.  For an explicitly coded action there would be all the annotations/metadata in @Action and @ActionLayout.  Where would that information be specified if the action is synthesized on the fly?  Would the @DomainObject annotation need to be extended instead as, for example:

@DomainObject(
    deleteAction=@Action(...),
    ...
)

I'm not completely convinced the extra complexity is worth it to save four lines of code.
