I'm currently trying to isolate the issue for you to reproduce in a small
test project.
In my last code snippet I forgot to add the call to omit the Ids
accidentally (as I have to remove allot of stuff to reduce complexity of the
code). So here it comes:
private static final Class[] CLASSES_TO_EXCLUDE_ID_FIELD = new Class[] {
WorkflowRole.class,
WorkflowRoleNameLocalization.class,
LocalizationName.class
};
protected void omitIDFields(final XStream xstream) {
for (Class clazz : CLASSES_TO_EXCLUDE_ID_FIELD) {
xstream.omitField(clazz, "id");
}
}
and the call to omitIDFields right before toXML call:
...
omitIDFields(xstream);
String xml = xstream.toXML(workflowRole);

I'll send an update once I've isolated a test case, so far no success to
reproduce in my test project.
Thanks,
