using NativeHistoricTaskInstanceQuery how to get variables on. HistoricTaskInstance

[nortobc]

I am using NativeHistoricTaskInstanceQuery to create a query that will return all tasks associated with a process containing a given task.   i.e. I only have a single taskId to query on.  This is working fine as I get a list of HistoricTaskInstance.  The problem is, the task/process variables associated with those tasks are not in the HistoricTaskInstance I am getting back.

Maybe a more direct question, is there a way to populate the queryVariables map in the HistoricTaskInstance using the NativeHistoricTaskInstanceQuery?
