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!
