Hi, Im not sure what you mean by "mixing several levels of complexity and functionality".. I tried to first describe the use-case and then how i plan to implement it as a workflow. Does that not make sense? I have read the white paper from van der Aalst (http://www.workflowpatterns.com/documentation/documents/BPM-06-22.pdf), and it seems to me like im trying to implement "Pattern WCP-21 (Structured Loop)" Im not sure if this is a valid case for BPM, if not, why? Thanks for your comment :-) -Kristoffer View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4063990#...
