>             Project: Isis
>          Issue Type: New Feature
>          Components: Core, Core: Viewer: Wicket
>    Affects Versions: viewer-wicket-1.7.0, core-1.7.0
>            Reporter: Dan Haywood
>            Priority: Major
>             Fix For: 3.0.0

> 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.
