HI all,

I use GWT 2.81 and EMF (Eclipse Modeling Framework) when i want send from 
the server to the client an object of my model, I obtain this final error:
com.google.gwt.user.client.rpc.SerializationException: Type 
'com.lacen.organisation.impl.RequirementImpl' was not included in the set 
of types which can be serialized by this SerializationPolicy or its Class 
object could not be loaded. For security purposes, this type will not be 
serialized.: instance = 
com.lacen.organisation.impl.RequirementImpl@2fa144e7 (name: Fkygrdphgf)

I have tried to understand how to use serializationWhitelist but I have no 
clear example.  The class RequirementImpl contains List, so I tried to 
create ArrayList with the good type, but same pb.

Can you help me, at least give me where found a claer explanation. 

Tanks a lot 
Antonio Guillen
