Miro, Your ReassignGrantsOfficerPage obviously _implements_ Serializable (since Component does, as you correctly say) but that does not mean that the subclasser can't break the contract himself by, usually inadvertently, giving his sub-class non-serialisable state! It seems that other people have experienced http://markmail.org/message/ddorsz5t5o3c2jnn?q=cglib+serialisable similar issues with CGLIB .
If you can't get around the CGLIB issue take a look at the 2 alternative approaches in my first response on this thread.
