When to use ValueProxy vs. EntityProxy

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
