Hi, I have a subprocess in my workfow, and a state node within. I can execute it, and it wait as expected in the state node. Until here, everything is ok. Now I want to signal the state node with : executionService.signalExecutionById(executionId). But the problem is : I don't know the executionId of the subprocess! I can't use : executionService.startProcessInstanceById(processDefinitionId).getId() either because I don't know the processDefinitionId since jBPM generates custom keys for subprocess! I have also tried to find the subprocess execution id from its parent process, but it doesn't seem possible to access child process from parent process. Did I miss something? I'm using v4.2 Thanks View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4267592#...
