Hi everybody,
I need to get the group tasks for which a user is candidate in a manner ORDERED e PAGED, so the API findGroupTasks is not sufficient.
Therefore, I have replaced findGroupTasks() with the following code:

+         taskList = getTaskService().createTaskQuery()
            .page(startRow, maxResults)

The problem is that the resulting list is not ordered.
By debugging jBPM sources, I've found that the problem is in the class org.jbpm.pvm.internal.query.TaskQueryImpl within the method

+public String hql()+

Here the ORDER BY clause is added only if I'm not searching for Candidate. The original code is the following:

+if (candidate == null && !count)

Why in your opinion is there such a condition?
How can I do to obtain an ordered and paged list for a candidate user?

Thanks you in advance,
