[OpenLayers-Users] Recenter map when Base Layer switched

[maw269]

I want to recenter the map when I switch base layers so the selected base
layer is in the viewport. The following code seems to work when the layer is
an Overlay but fails when it is a Base Layer.

os_street_view.events.register('visibilitychanged', this, function()
{
	var os_street_viewvisibility = os_street_view.visibility;					
	if (os_street_viewvisibility == true)
	{			
		var osExtent = new OpenLayers.Bounds();					
		osExtent.extend(new OpenLayers.LonLat(-8, 50).transform(g,p));
		osExtent.extend(new OpenLayers.LonLat(6, 55).transform(g,p));
		osExtent.toBBOX();
		map.zoomToExtent(osExtent);							
	}
});

Any thoughts?
