Ok, sounds good. I'm going to change the current @ManagementProperty.marshallerFactory field to a MetaMapper from an InstanceClassFactory as that iface has too evolved into something beyond a simple MetaValue/value conversion iface. I'm going to create a MetaValueMapper interface that MetaMapper implements and use MetaValueMapper as the ManagementProperty.valueMapper field. https://jira.jboss.org/jira/browse/JBMAN-43 https://jira.jboss.org/jira/browse/JBMAN-44 View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4191485#...
