I think this is a different symptom of the same underlying problem that Lukasz reported. I'll try to confirm this in a few hours...

Wrong thought or bug? Cheers, Georg _______________________________________________ qi4j-dev mailing list [email protected] http://lists.ops4j.org/mailman/listinfo/qi4j-dev
