Sorting List of tasks

[Former Community Member]

Hi, I've created a custom componet to retrieve task information, I use TaskSearchFilter to search the tasks, but how can I sort the task list?

I know there is filter.addSortDesc(String) and filter.addSortAsc(String), but I am not sure what to put if I want to sort by task id or completion date.

I tried to put addSortDesc("TaskId") or addSortDesc("Id") but it seems not working. Is there any docs/reference available for the list of attributes I can sort by?

thanks

There is a constants file in the taskmanager client jar. Here is a sample of how we use the filter to get tasks for a provided processinstanceid. We did the sort on pCREATION_TIME but this could easily be changed to pID to sort by task id.

TaskManagerQueryService tmqs = TaskManagerClientFactory.getQueryManager(clientFactory);

TaskSearchFilter taskSearchFilter = new TaskSearchFilter();

taskSearchFilter.addSortDesc(TaskSearchingConstants.pCREATION_TIME);

taskSearchFilter.addCondition(TaskSearchingConstants.pPROCESS_INSTANCE_ID, Operator.EQUALS, Long.valueOf(processInstanceId));

List results = tmqs.taskSearch(taskSearchFilter);

Hope this helps.
