P1 is my main process which in turn calls P2 and P2 calls P3. In my case P1 executes fine and calls P2. When P2 reaches its End node i get this error. Folliwing are the process def. files for the processes. <?xml version="1.0" encoding="ISO-8859-1"  ?> # - <process-definition name="*P-1*"> # - <swimlane name="*TestSwimlane*">   <assignment pooled-actors="*TestSwimlane*" />   </swimlane> # - <start-state name="*s1*">   <task name="*s1*"  swimlane="*TestSwimlane*" />   <transition to="*t1*" name="*to t1*" />   </start-state> # - <task-node name="*t1*"> # - <task name="*t1*"  swimlane="*TestSwimlane*">   <controller allowAttachments="*false*" />   </task> # - <transition to="*e1*" name="*to e1*"> # - <action class="*com.mypack.process.action.CallProcess*" config-type="*bean*">   <processName>A-2</processName>   </action>   </transition>   </task-node>   <end-state name="*e1*" />   </process-definition> Second Process: <?xml version="1.0" encoding="ISO-8859-1"  ?> # - <process-definition name="*P-2*"> # - <swimlane name="*TestSwimlane*">   <assignment pooled-actors="*TestSwimlane*" />   </swimlane> # - <start-state name="*s2*">   <task name="*s2*"  swimlane="*TestSwimlane*" />   <transition to="*t2*" name="*to t2*" />   </start-state> # - <task-node name="*t2*"> # - <task name="*t2*"  swimlane="*TestSwimlane*">   <controller allowAttachments="*false*" />   </task> # - <transition to="*e2*" name="*to e2*"> # - <action class="*com.mypack.process.action.CallProcess*" config-type="*bean*">   <processName>A-3</processName>   </action>   </transition>   </task-node>   <end-state name="*e2*" />   </process-definition> Third Process: <?xml version="1.0" encoding="ISO-8859-1"  ?> # - <process-definition name="*P-3*"> # - <swimlane name="*TestSwimlane*">   <assignment pooled-actors="*TestSwimlane*" />   </swimlane> # - <start-state name="*s3*">   <task name="*s3*"  swimlane="*TestSwimlane*" />   <transition to="*t3*" name="*to t3*" />   </start-state> # - <task-node name="*t3*"> # - <task name="*t3*"  swimlane="*TestSwimlane*">   <controller allowAttachments="*false*" />   </task>   <transition to="*e3*" name="*to e3*" />   </task-node>   <end-state name="*e3*" />   </process-definition> Code : public void execute(ExecutionContext executionContext) throws Exception {         // debug("entering call process action handler");         String name = null;         try {             name = getProcessName();                        ProcessInstance processInst = ProcessUtil.newProcessInstance(name);             Task task = Util.getStartTask(processInst.getProcessDefinition());             Token superProcessTOken = executionContext.getToken();             processInst.setSuperProcessToken(superProcessTOken); *// If i comment this line i don't get this error.*            ........code to extract caller data......             TaskInstance ti = Util.initProcess(processInst, task, values,                     false);             if (ti != null) {                 // setup the swimlane instance                 Swimlane swm = ti.getTask().getSwimlane();                 if (s != null) {                     String assignment = swm.getPooledActorsExpression();                     if (!Strings.isEmpty(assignment)) {                         ti.getSwimlaneInstance().setPooledActors(                                 assignment.split(","));                     }                     ti.end();                 }             } I hope now you can understand. -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/548197#548197] Start a new discussion in jBPM Development at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&...]
