How to get approver for a content?

[dynamolalit]

Hi All,

I have an approval workflow having different approver groups for different spaces.

I want to know how can i get approver/s for a content which is under workflow in repository.
OR
Alternatively, how can i get number of approvals pending against each of approvers in repository?

Any help will be highly appreciated.

Hi All,

I have implemented a web script to get list of all approvers who are having any pending approvals for a particular workflow definition inside repository.It works on basis of groups which are having approvers in it.

It checks for all in progress tasks for a particular workflow & get {http://www.alfresco.org/model/bpm/1.0}pooledActors for each of such task & then get noderef for each such approver group & finally get all children in each of such group which are none but users who are approvers for this group & get each approver's user name & send it back as json object.

public void execute(WebScriptRequest request, WebScriptResponse response)
         throws IOException {
      logger.debug("Inside execute of WebServiceHelper");      
      //Searching for in progress reviewTasks in repository as xxxx Approval WF is using the same.
      QName taskName = QName.createQName("http://www.alfresco.org/model/workflow/1.0", "reviewTask");
        WorkflowTaskQuery workflowTaskQuery = new WorkflowTaskQuery();
        workflowTaskQuery.setActive(true);
        workflowTaskQuery.setTaskName(taskName);
        workflowTaskQuery.setTaskState(WorkflowTaskState.IN_PROGRESS);   
        //Get List of such tasks using WF Service.
        List<WorkflowTask> pendingTasks = getWorkflowService().queryTasks(workflowTaskQuery);
         for(int i = 0; i < pendingTasks.size() ; i++ ){ 
            WorkflowTask currPendingTask = pendingTasks.get(i);
            //Get WorkflowDefinition name for each task in this list.
