How, where? | But there is no actual runtime component invocation at the moment, right? | The ManagedProperty Fields implementation needs an advice that catches the setValue call to write the update onto the metadata instance property the field is associated with. This would apply for javabean type of metadata. Other implementations could be specified for different metadata types. We are missing the setup of the Fields proxy. The fields creation in AbstractManagedObjectFactory needs to be using the org.jboss.managed.plugins.advice.WrapperAdvice.wrapFields utility to allow an advice to update the metadata instance on the setValue call.
