When you say recreate again what exactly do you mean? Do you create a new context? If so do you also create a new Camera for it as well? Or just assign it to the original Camera? Why do you call close() rather than just removing the Camera from the View, or View from the CompositeViewer? The later is how I'd tackle this type of task. You don't say what type of Viewer you are using or how you've assigned your Camera so I can't say specifically about how to remove what you have.
