Externalization and datacache

Question

Hi,
i have a problem with the externalization framework and the datacache:
My persistence class 'A' has a field 'f' of custom type that have
references to other persistent objects.
This field is stored using the externalization framework and my factory
method receives the persistence manager instance associated to the A
instance.
I'm getting an existing instance of A from a new persistence manager (with
the PersistenceManager getObjectById method). When the instance is already
present in the datacache,
the factory method is not called and my field f contains references to
persistent objects associated to another persistence manager (the one i
used when i first access the instance).
It works fine when my instance of A are not already in the datacache since
the factory method is called and the references are retrieved from the
current persistence manager.
Tell me if i miss somthing in the framework or if there is a workaround.
I've tested it with versions 3.0.3 and 3.1rc2. I'm using Kodo in Stateless
Session Beans and get a persistence manager in each bean method as
suggested in the documentation.
Thanks for your help

Answer 1

Well, one solution (if you can call it that) is to just disable data
caching for the class that owns the externalized field:
<class name="XXX">
<extension vendor-name="kodo" key="data-cache" value="false"/>
</class>
Other than that, I can't think of any workarounds.
