Smart dashboard writing values to the robot

[tdbroun]

Our team is trying to use the smart dashboard to process vision on the laptop and send motor values to the robot to aim at the target. We have the vision processing working. We lock on to targets and can set a motor value in the dashboard project vi.
We use the SD write dbl vi to send the value to the robot, and our trouble begins. When we run the code, we get an error in "handle dirty elements.vi" on the client/server selector, all the way to the left of the vi. The isclient boolean seems to be the cause.
If we pop open the panel for "handle dirty elements.vi" and set it to true, we can run and pass data to and from the robot from the smart dashboard.
Is there some initialization that we need to do to get this to work without intervention? What vi calls handle dirty elements?
Is there a smart dashboard white paper that might explain this?
