how to set the task priority on the bpmn20.xml

This is a simple thing but I can't find it anywhere.programmatically: org.activiti.engine.task -> setPriority()

Nothing is available at the moment to specify the priority on the task-definition. Can you create a jira task for this feature?

here: http://jira.codehaus.org/browse/ACT-797

Best solution I can think of is using a TaskListener and field-injection to set the priority in your definition, eg:
(don't mind the syntax, just from the top of my head)


<userTask id="task1" name="My task" >
  <extensionElements>
    <activiti:taskListener event="create" class="org.activiti.SetPriorityTaskListener">
       <activiti:field name="priority" stringValue="1234" />
    </activiti:taskListener>
  </extensionElements>
</userTask>


public class SetPriorityTaskListener implements TaskListener {
  
  public Expression priority;

  public void notify(DelegateTask delegateTask) {
    delegateTask.setPriority((String)Integer.valueOf(priority.getValue(delegateTask)));
  }

  // get and set priority
}

That's the only workaround I could think of. You're always free to submit a patch for the issue you reported…

Does it work with a single task? AFAIK, tasklisteners are called on each instance…

There is a slightly easier way to achieve the same thing until this is fixed. Add the following listener to the task elements:


<extensionElements>
    <activiti:taskListener event="create" expression="#{task.setPriority(100)}"></activiti:taskListener>
</extensionElements>
