Hi there, 

I thought that if I want GWT only send delta changes to server, then 
EntityProxy is a better fit. 

I just realized that EntityProxy is also a better fit if you do not want 
you persistence layer load the entire object tree (ends up loading too much 
data in server) every time you ask for the top level object.

With GWT 2.5, I declare all my data objects are value proxy with JPA 
relationships set up on server side. I noticed that, even with LazyLoading 
setup in JPA, the server is still loading everything. This is because GWT 
is traversing all properties on a the class implementing ValueProxy 
interface and loads every property. Is that correct?

Thanks,
Yan
