I'm using LoadableDetachableModels to minimise the serialized session state
of my app. However, there is one place where I am still seeing
WicketNotSerializableException and that is where I use a hibernate
collection as a components model.

I have a SystemUser class which contains a List of Contact objects - both
are hibernate entities. This collection of Contact objects form the model
for a ListView but throws the WicketNotSerializableException as follows...

[snip]
private java.lang.Object
org.hibernate.collection.AbstractPersistentCollection.owner
[class=com.myapp.domain.SystemUser] <----- field that is not serializable


So it seems that the underlying hibernate collection has a field 'owner' (in
this case the SystemUser) which wicket is trying to serialize. I'm not sure
of the best way to make this owner object (and the collection objects
themselves, probably) LoadableDetachableObjects.

Any ideas?

Thanks - Neil.
