Petia, This shouldn't be necessary. I'm not saying it ISN'T necessary in some context - but I can't imagine what it is. It'll be interesting to see if it helps Arutha. This is the kind of problem I'd debug into JBPM to figure out. However, be warned - the variable-handling code is probably a lot more complex than you would expect. -Ed Staub View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4083578#...
