Update task workflow property inside a scriptTask

[theoryoflinkin]

Hi,

In my workflow (developped with Activiti), I just want to implement a TimerEvent on a UserTask.

After 15 days, I want this TimerEvent to call a ScriptTask.

In this ScriptTask, I just try to update the "priority" property of my UserTask and set it to 1 (high).

Can someone help me please? I can't find what to write inside my ScriptTask…

Thanks in advance

<serviceTask id="yourscripttask" name="your script task" activiti:class="org.alfresco.repo.workflow.activiti.script.AlfrescoScriptDelegate">
   <extensionElements>
       <activiti:field name="script">
          <activiti:string>
            var taskId = "activiti$yourscripttask";//where yourscripttask is the task id you defined in serviceTask id="yourscripttask"
                var taskInstance = workflow.getTask(taskId);
            taskInstance.priority=***;
            //or just use direclty
            taskInstance.priority=***;
         </activiti:string>
       </activiti:field>
    </extensionElements>
</serviceTask>
