Sonny Gill commented on QI-72:
------------------------------
This only happens if AComposite extends EntityComposite, and not if it extends
Composite.
So, it would appear that the problem is because of -
if( EntityComposite.class.isAssignableFrom( mixinType ) )
{
return ( (ModuleInstance) module ).findEntityCompositeFor( mixinType
);
}
return ( (ModuleInstance) module ).findCompositeFor( mixinType );
in the method Qi4jRuntime.getCompositeDescriptor( Class mixinType, Module
module )
and the fact that AComposite is now added with a module.addEntities(...) call.
> Qi4jRuntime.getCompositeDescriptor() causes NPE when called with the domain
> interface for an EntityComposite
