Hello
I can't seem to be able to claim/start a task , getting the following error :
org.jbpm.task.service.PermissionDeniedException: Server-side Exception: User '[User:'john']' does not have permissions to execution operation 'Claim' on task id 3
I am using the demo setup of JBPM 5.1, launching through the jbpm-installer provided with the install package. I am using the user "john" and group "PM" provided in the mvel files that come with the demo setup.
The error occurs when claiming the task , with the following code :
try{
TaskClient client = new TaskClient(new MinaTaskClientConnector("client 1", new MinaTaskClientHandler(SystemEventListenerFactory.getSystemEventListener())));
client.connect("127.0.0.1", 9123);
Thread.sleep(1000);
// getting potential tasks for user "john"
List<String> groupsJohn = new ArrayList<String>();
groupsJohn.add("PM");
//display tasks
BlockingTaskSummaryResponseHandler taskSummaryResponseHandler = new BlockingTaskSummaryResponseHandler();
client.getTasksAssignedAsPotentialOwner(null,groupsJohn, "en-UK", taskSummaryResponseHandler);
List<TaskSummary> myTasks = taskSummaryResponseHandler.getResults();
//...
//Claim task for John & start it
BlockingTaskOperationResponseHandler taskOperationResponseHandler = new BlockingTaskOperationResponseHandler();
client.claim(3, "john", taskOperationResponseHandler );
taskOperationResponseHandler.waitTillDone(1000);
}catch (Throwable t) {
t.printStackTrace();
}
I have checked the following already :
- Task status for Task id 3 is "Ready", no actor assigned yet.
- Group and actor names are correctly defined in the mvel files.
- The Human Task node in my flow has the Group "PM" defined in its group property, and the actor id is left empty.
- If i assign actor "john" to the human task in the bpmn flow , I can start the task correctly
- I can start the task using Administrator.
- getTasksAssignedAsPotentialOwner("John",groupsJohn, "en-UK", taskSummaryResponseHandler)gives the same error as the line above
So it really has to do with the group , but I can't figure out why ...
