Deleting the route xml file will not remove the visual rider ide of the routes

I am following the tutorial
http://fusesource.com/docs/ide/camel/1.0/tutorials/tutorials.html

And it says that you should delete the camelContext.xml file and create a new file.
But before I did that, i double clicked the camelContext.xml file, so it popup in the rider (visual eips).
So after that I delete the file, but the rider screen keeps showing.

I think the rider screen should disappear if the file is deleted from the project.
