The wiring is still pretty wired to me,

(with all these indirections and wirings it gets pretty hard to find something ;-)).

Hey Tom. A very quick question, because I start to integrate EJB3 Entities as process variables. 1. What’s wrong with that? The wiring is still pretty wired to me, but this should work, right? I always get a Nullpointer, even if the class exists: error: matcher is not a org.jbpm.pvm.internal.type.Matcher: null <type name="ejb3-long-id" id-type="long" variable-class="de.dillinger.stw.jbpm.Ejb3LongEntityVariable"> <matcher><object class="de.dillinger.stw.jbpm.Ejb3LongMatcher" /></matcher> </type> 2. What do you think of this approach: http://www.jboss.org/index.html?module=bb&op=viewtopic&t=161886 <http://www.jboss.org/index.html?module=bb&op=viewtopic&t=161886>;. Wouldn’t the better way be to integrate that with a Matcher and Type? Or what do you think about that proposal, seems a bit wired to me? Thanks a lot! Sorry for newbie questions, still try to understand some stuff in the engine (with all these indirections and wirings it gets pretty hard to find something ;-)).
