I tried to use Gilead but it's bad that:

  1. it is so invasive;
  2. it is so hard to configure.

I wrote a small class that converts hibernate proxies to normal java classes and it really helps me. It is shared as open source there, so you could try:

I could not solve this problem, but i did a little workaround: I cloned my entities on the client side and then i could send them back to server side.
