Anyone can help me?
Thanks!

Thanks to Bruno (hibernate4gwt forum); he suggest that the problem can be of the EXT GWT Style class that is not a pure POJO (meaning it has not an empty constructor).

So my question is: EXT GWT can make this class a pure POJO class in order to permit hibernate4gwt to work?

Thanks!

i have the same problem...

Are you guys implementing serializable for all your RPC passed objects?

[fother]

yes... to solve this problem.. I create a simple pojo that have the attributes that i really will to use.

See:

http://beanlib.svn.sourceforge.net/viewvc/beanlib/trunk/beanlib-doc/faq.html

For alternative solutions.

This is the correct solution - you should really use a POJO to send when using RPC
