I don't think the map really solves all the problems. Since afair we have some beans that have properties with the same name but different types. Dunno how much against JavaBeans is this, but I think we should still be able to support is - which is somehow harder to do with map. What about just some useful merging methods on (Abstract)BeanMetaData? View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4249383#...
