I have process that invoke sub process using process state. I test the process with JUnit. When start test it says - ERROR (GraphElement.java:295) - action threw exception: can't create a process instance when processDefinition is null. This is because can't find the sub process definiton. How can I bound sub process definition to parent process definition. This is my code in JUnit test | ProcessDefinition definition = ProcessDefinition | .parseXmlInputStream(new FileInputStream("jpdl\\parent\\processdefinition.xml")); | ProcessDefinition definitionSub = ProcessDefinition | .parseXmlInputStream(new FileInputStream("jpdl\\sub\\processdefinition.xml")); | ProcessState st = (ProcessState)definition.getNode("Sub process Invoke"); | st.setProcessDefinition(definitionSub); | ProcessInstance instance = new ProcessInstance(definition); | instance.signal(); | View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4203761#...
