Dear vergude,

Code for get All Task:


WorkflowTaskQuery query = new WorkflowTaskQuery();
query.setTaskState(WorkflowTaskState.COMPLETED);

List<WorkflowTask> result = this.workflowService.queryTasks(query);
‍‍‍‍‍‍

Dear vergude,

I see you are doing what vinaxwater suggests already:


      WorkflowTaskQuery workflowTaskQuery = new WorkflowTaskQuery();
      workflowTaskQuery.setTaskState(WorkflowTaskState.COMPLETED);

      List<WorkflowTask> tasks = getWorkflowService().queryTasks(
            workflowTaskQuery);
‍‍‍‍‍‍‍

The getWorkflowService() is the new way; they don't have workflowService instance variable in Workflow class anymore.

I am thinking maybe the problem lies wherever you call this.services:


         items.add(new WorkflowTaskItem(this.services,
               getTemplateImageResolver(), task));
etc…

      return this.services.getWorkflowService();
‍‍‍‍‍‍‍

You can't access Workflow.services; it's just getWorkflowService()

Have a look at this page: http://www.wowww.nl/wordpress/2007/09/14/creating-an-alfresco-task-history-the-java-style/… Marc has a nice explanation; although I believe he is using the old-style coding too. But you can see what he is doing if my suggestion doesn't work for you

Thanks for answers.

This is my code. It works and I can see all completed tasks.

QName taskName = QName.createQName("http://www.alfresco.org/model/workflow/1.0", "adhocTask");
       
       // get all "completed" adhoc Tasks 
       WorkflowTaskQuery workflowTaskQuery = new WorkflowTaskQuery();
       workflowTaskQuery.setActive(null);//this is very important
       workflowTaskQuery.setTaskName(taskName);
       workflowTaskQuery.setTaskState(WorkflowTaskState.COMPLETED);
       
        List<WorkflowTask> completedTasks = getWorkflowService().queryTasks(workflowTaskQuery);‍‍‍‍‍‍‍‍‍
