[OpenLayers-Users] LoadingPanel - Waiting for Vector & WFS loading

[Phil Scadden]

Well I still think you should WMS to display the huge amount of data 
instead but...

                     map.div.style.cursor = 'wait';
                     loadingPanel.maximizeControl(); // and stop with 
minimizeControl();
is how I tell users to wait. You can attach to loadstart and loadend 
events. Loadingpanel does this automatically for WMS, dont know why it 
isnt for WFS
