Thanks for the advice. Its is nice to know that I am not alone.
I have been using the debugger to examine the objects hibernate uses.
The object I am marshaling has a field called 'state' which is defined
to be a EntityState object. So my Castor mapping is
<field name="State" type="inform.orm.entity.EntityState"
container="true"/>
and
<class name="inform.orm.entity.EntityState" auto-complete="false">
<field name="description">
<bind-xml name="state" node="attribute" />
</field>
</class>
However when I examine the class with the debugger, I find that the
actual object in field 'state' is an instance of
EntityState$$EnhancerByCGLIB$$c147c74c It looks as if hibernate is
doing some bit code enhancement (even though I have configured it not
to)
I presume that Castor, as it doesn't find the expected object, starts
inspecting all the fields on the object.
If this is correct, I suspect that a better approach would have been to
only inspect the fields that the expected object had listed. E.g in my
case it should have simply inspected the description field.
