Thanks for your reply, The variable element is only dealing with variables copy from the super process to the sub one :( . I was looking for a simple way to initialize the subprocess instance's key by using the super process instance's one. I could handle this issue by implementing 2 handlers, listening to the subprocess creation event and to the process start event in the subprocess. The first copies the key into the variable map, and the second uses the "key" variable to set the instance's key View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4166575#...
