Can't deploy code to robot

[Whippet]

We had the same issue, removing any SmartDashboard references fixed it.

The code is deploying just fine. This error simply means that it couldn't find an older running version of your code to kill before loading the new one.

This is very likely because your code is crashing when it starts. Use the riolog to find out what exception is being thrown where so you can fix it.

Were you trying to do an autonomous selector on the SmartDashboard?

Because this code would cause our robot to crash in autonomous:

	SmartDashboard::PutData("AutoCommand1Can", autoCommandMoveToZone); 
	SmartDashboard::PutData("AutoCommand1Can", autoCommand1Can); 
 	SmartDashboard::PutData("AutoCommand1Can", autoCommand1Can1Tote);

The problem was buried deep in the NetworkTables code. I believe one of the STL mapping classes would return a null pointer on an attempt to add a duplicate key to the map, and the code wasn't checking for that.

I've been meaning to report it to the WPILib people, but I've been kind of busy..

Yeah, that was the problem.

Might have you covered on the bug report.

Apparently you do.

I actually had this narrowed to the exact place in Network Tables that this happens, but as this was in the middle of the competition, at the time I was satisfied without simply fixing our own code to make it not happen.

After St Louis, I might give actually go back and and suggest a precise fix.
