solves the client/server object serialization issue.

Hey Timothy,
yes you are allright and a colleague and me found out that we have to
transform the object in the RPC call. Therefore gwt offers a method :
net.sf.gilead.gwt.clone(Object hibernatePojo)
this transforms the object to POJO.

Well I have the famous failure with GWT and Hibernate:

The basic answer is you cannot. You will need to transform the Hibernate object
into a POJO to make it serial, this is a requirement of any object being passed
between the client and the server in GWT.
