Hibernate: attempt to create saveOrUpdate event with null entity

[grasshopper]

Hello all,

I am getting the following exceptions when I try to save, delete or
update an entity from a GWT app. Both front-end and back-end entity
classes are serialized. One interesting behavior I see is that i can
pull a list of entities just fine from server just not save, delete or
update.

It sounds like you lost your conversational state within hibernate.
