Which wiki page do we have to use to configure dpHibernate?

[NargiT]

Hey guys,

I'm trying to configure my Spring BlazeDS integration with Hibernate
project, and I reach the point were I need to use lazy loading for my
database. Because I have some serious latencies thanks to BlazeDS.

Anyway I discover dpHibernate but I can't make it run, I have some
configuration issues ^^.

Can someone help ?

I use
Spring BlazeDS integration 1.0.3
Spring 3.0.5 and Flex 4
Hibernate 3.6.4

Ok I have something working here. The problem is that my value object
on the client side are only set for basic types (String, integer) but
my arraycollection is null.

I have a User which has an ArrayCollection of Rights.

When in the client side I'm doing .rights I have a null pointer
exception. And I checked with the debbuger, the service (server side)
returns the good object, with the set of right initialized to
"Persistent Set". The exception that I post before appear before the
client application is called.

What should I expect to see in a proxy field?
