Hey all,
after searching the whole for a solution for my problem I am now sharing my problem to you ;).
Well I have this famous error:
I know the description of google where they mention this problem.
Well what I don't understand is this: they still use the hm.xml file to generate the enities right? But how do they make them extending from LightEntity when the entities are generated?
I am asking this because I also generate my entities via Hibernate and this xml:
well and this is my generated class out of this:
in general without the "LigthEntity" extending because that was just a try as you can see at the comment in the xml file right to the < meta> -Tag. In general it just implements BasisEntity and Serializable.
So what can I do to solve my problem that the Set is understood in the browserworld?
I really have no clue anymore how to solve this. so please help me :)
Thanks!

-- after searching the whole for a solution for my problem I am now sharing my problem to you ;).
Well I have this famous error:
java.lang.RuntimeException: com.google.gwt.user.client.rpc.SerializationException: Type 'org.hibernate.collection.PersistentSet' 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 = []
I know the description of google where they mention this problem.
Well what I don't understand is this: they still use the hm.xml file to generate the enities right? But how do they make them extending from LightEntity when the entities are generated?
I am asking this because I also generate my entities via Hibernate and this xml:
