Description

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.
