Never seen this one. Are your machine and your colleague's running the same versions of the JDK, JBoss AS, jBPM BPEL?
As an alternative, consider upgrading to jBPM BPEL 1.1.Beta3 and JBoss AS 4.0.5.
actually I have tested many different configurations. My biggest surprise -> After Testing it in different ways it now works.
But don't ask me why case I haven't really changed anything.
Yes - I will update to bpel beta3 - another big question: When will we get the relase candidate?
Wouldn't it be better to wait for this one? Or will I have to wait a longer time?
