There was the question of primative types vs SimpleMetaType and whether the ManagedProperty should be accepting primatives and autoboxing these into SimpleValues. I think we should look into doing this. The question also came up of enforcing a check against the ManagedProperty.getMetaType().isValue(Object) for the values passed into ManagedProperty.setValue(Object). Could be done with aop, but I don't think we can assume jboss aop is available/used in the admin client. It could also be done via a wrapping proxy that imposed this behavior, as well as the autoboxing. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4114392#...
