Refreshing Dashboard and Parameters after a DM Job

I want to run a DM job from a dashboard (with the task popup showing progress, so no background running) and then when finished have the originating dashboard refresh after updating a parameter used in the dashboard.   If I call the DM job directly from the dashboard I am not sure how to return a task result that will update the parameter value in the dashboard.  I tried using a BR that called a DM job and then updated the parameter and refreshed the screen. However, when running it this way the popup did not appear and it just froze the screen, sort of negating the value of using the DM job.  Has anyone successfuly tried to do something like this before?
