GWT RequestFactory can not update object graph

Question

At my client side the code like this:

@ProxyFor(...)
public interface AProxy
{
  BProxy getChild();
  void setChild(BPorxy child);
}

RequestContext ctx=...
AProxy parent=...
AProxy a=ctx.edit(parent);
a.getChild().setContent("new content");//update content
ctx.save(a).fire();

From the browser debug console i can see the request is sent to server with the updated new content, but from server side's save(A a) method, the content of child b is the same as before(never changed), but other update in a is reflected.

And I use Locator at server side. No problem when creating the entity graph, just can not be updated.

Anyone shed some light on what's the problem here? Thanks

It must be that you have 2 distinct B instances for the "same" entity and/or setChild does a copy of its argument.

Set appropriate breakpoints in locators and setters to debug it (pay attention to the object id)
