Hi Hiram;

I will try to give a possible reason ..

Not all the attributes in the GBeans are serializable, e.g.

those so called magic attributes get the values from the enviorment ..
so serializing them do not make sense. I belive this is a reason
making attributes Serializable (only the persitant ones), but not the
