When they are creating or editing an object, users may want to navigate the view. They want to pan the map to bring the position of the next object handle into view, for example.
The lightspeed.editing
sample shows how you can make view navigation during shape creation possible.
Sample users can still use the middle mouse button to pan around while they are creating a shape.
The sample demonstrates the principle of controller chaining by combining the navigation controllers with a create controller.
