JBossDeveloper

Hello Marco,

I use Jboss 7.

These are two bpmn2 files : first is a complete flow with dynamic assignation, and the second is a flow with a single human node but also with dynamic userId.

I look at your POM example for the branch 5.4, you don't use context injection? I use it, but if I can give you other files to help you make your example, no problem.

Finally, I set the assignation and other dynamic variable with outputparameters.

First I encounter a runtime exception but it was due to mySQL who creates all foreihn keys with restric cascading and prevent jbpm from updating task parameters.

I just change the cascading type directly in the database and now it's works fine.

In the step validation (java code):

Map<String, Object> results = new HashMap<>();
                    results.put("userAssign", userAssign);
                    results.put("groupAssign", groupAssign);
                    results.put("formValid", formValid);
  
                    taskManager.completeTask(taskManager.getManageTask(),results);

Thank you very much again Marco!

Hello,

Thank you for the link. Indeed, when I don't use persistence I just used the workflowProcessInstance and it works great. And the NullPointerException apear after changing to persistent session.

But, I already try the command base approach and in my case it doesn't change anything. 

My conclusion that seams to work for now is :

WorkflowProcessInstance wpi = (WorkflowProcessInstance)kSession.getProcessInstance(processInstanceId);
 wpi.getVariable(key);

to access variables even if I use persistent session.

and define output parameters mapped to process variables directly inside the process and pass a map of results to the complete task method to dynamically change process variables.
