I'm not sure what "META_OBJECT" (all caps) is, or where it's defined. Did you intend to use "META_Object" from include/osg/Object instead?
One other possible issue I noted: Assuming you intended to use META_Object, I believe you are required to implement the copy constructor, and I don't see that in your code...
