There was a bug in method VariableTypesBinding.parseTypeMapping(). It expected "class" attribute in xml to be set to "persisted" and I chcnged it to "hibernate":
   // if type="hibernate"
  |       } else if ("hibernate".equals(className)) {

But I think code in HibernateLongIdMatcher is broken as well. 
if (environment!=null) {
  |       SessionFactory sessionFactory = (SessionFactory) environment.get("hibernate.session.factory");
  |       if (sessionFactory!=null) {
  |         ClassMetadata classMetadata = sessionFactory.getClassMetadata(value.getClass());
  |         matches =  ( (classMetadata!=null)
  |                      && (classMetadata.getIdentifierType().getClass()==LongType.class)
  |                    );
  |       }

First you should to ask if value is not a HibernateProxy cos in that case you wont get any metadata (as done in jBPM 3)..

  |     Class valueClass = value.getClass();
  |       if (value instanceof HibernateProxy) {
  |         valueClass = valueClass.getSuperclass();
  |       } 

And second. How can you get SessionFactory from envoronment? The interface has only addContext(Context) method and SessionFactory does not implemenst Context. But maybe I shoul implement my own  Environment and fill it in another way than throgh Environment interface. Maybe my bad.

What do you think?
