[udig-devel] Set Map Extent 
Hello,

I am trying to set the extent in the mapviewer (RCP example) programatically after adding some layers with no luck. If I put a button in the toolbar to execute the following action when clicked:

    class SetExtentAction extends Action {
        public SetExtentAction() {
            super("Set Extent"); //$NON-NLS-1$
        }
        public void run() {
		ReferencedEnvelope bounds = new ReferencedEnvelope(new Envelope (2000000, 8669445.545, -3334722.765, 3334722.78), DefaultGeographicCRS.WGS84);
		map.sendCommandASync(new SetViewportBBoxCommand(bounds));
        }
    }

It works, but I need to click a button and I would prefer to set the bounds from the code so I dont have to click a button.

If I use this:
	map.getViewportModelInternal().setBounds(new ReferencedEnvelope(new Envelope (2000000, 8669445.545, -3334722.765, 3334722.78),DefaultGeographicCRS.WGS84));
After creating the map, it works if I dont add layers, but it seems like everytime a layer is added the map is zoomed to the layer extent.
Since the layers are added using 
       map.sendCommandASync(new AddLayersCommand(dataHandles));
I dont know where to place the code for setting the extent, and which method to use (map.getViewportModelInternal().setBounds or SetViewportBBoxCommand), where would be a good place??

Thank you!!
