MetaValueFactory.create() methods require that you supply a value. What if all you want is a MetaValue object that has no value in it yet. Basically an empty instance. It would be nice to have a method like create(MetaType metaType) and it returns a MetaValue object of the correct type, that can be filled in later with a setValue() Maybe I am just missing something, and that functionality is already there. At this moment, I just know the MetaType. I can, of course, go through the isXXX methods of MetaType and instantiate each Value object with "new" (Which is what I am going to do for now). But it would be cleaner in the MetaValueFactory object. Thanks View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4127672#...
