I'm passed these problems now - a couple of things i learned when
creating object and storing in data nucleus for later retrieval over
an RPC call
- Most importantly, if you are returning a complex object (like one
with a list of another type of object) you need to return a copy, not
the object
Hi,
I'm using JDO with App Engine and GWT and sending the domain objects
with the JDO tags via RPC is working fine, so not sure if the problem

The problem comes from instrumentation done by the ORM. Most of the
ORM substitute the implementation of the List, Map or Set with their
own implementation since they need to track invocation of method of
the collection. I know that the latest GWT 2.0 code base is putting

Hi, I was experimenting with it a bit as well and it seems to me that
even the most simple Entity bean cannot be passed through RPC call. I
had a simple class:
@Entity
public class Tournament implements Serializable {
@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
I'm struggeling with this now - did you guys solve it? I have a

Are the List fields on your objects specified in terms of interfaces?
GWT RPC needs to know as much about your objects at compile time,
could you try using a concrete class instead - preferably ArrayList?
It sounds like you're trying to serialize ORM objects directly, is
that right? I don't
