task property update with runAs System

vincent-kali

When trying to update a task property (bpm:comment) with code run as system, the update is just not applied (but no exception thrown). When executing the code as the task assigned user, it works fine.

Any idea ?

The code:

try {
 if (userIsProcessManager) {
  AuthenticationUtil.setRunAsUserSystem();
  logger.debug("Running as system user");
 }
     
 WorkflowTask task = this.services.getWorkflowService().getTaskById(taskId);
 if (task == null){
  logger.error(ERR_MSG_INCORRECT_TASKID);
  throw new WebScriptException(ERR_CODE_BAD_REQUEST, ERR_MSG_INCORRECT_TASKID);
 }
     
 if ((!userIsProcessManager) &&
  (AuthenticationUtil.getFullyAuthenticatedUser().compareToIgnoreCase((String) task.getProperties().get(ContentModel.PROP_OWNER)) !=0)){
  logger.error(ERR_MSG_INCORRECT_TASK_ASSIGNEE);
  throw new WebScriptException(ERR_CODE_BAD_REQUEST, ERR_MSG_INCORRECT_TASK_ASSIGNEE);
 }
      
 Map<QName, Serializable> props = this.getPropertyMap (...);
 this.services.getWorkflowService().updateTask(taskId, props, null, null);
 if (endTask) this.services.getWorkflowService().endTask(taskId, null);
    
}finally {
 AuthenticationUtil.clearCurrentSecurityContext();
}

It's finally working fine (A dummy bug fixed).
Sorry for this useless post.

Just to share the code for task update:

Code reference from alfresco:
 org.alfresco.repo.web.scripts.workflow.TaskInstancePut
 org.alfresco.repo.workflow.TaskUpdater

My code using RunAsWork:

 finalTaskState = AuthenticationUtil.runAs(
  new AuthenticationUtil.RunAsWork<String>() {
  public String doWork() throws Exception {
   logger.info("Running update task as: " + AuthenticationUtil.getRunAsUser());
   ...
   workflowService.updateTask(taskId, taskProps, null, null);
         if (endTaskRequested) workflowService.endTask(taskId, null);
         return task.getState().toString();
  }
 }, AuthenticationUtil.getSystemUserName());
