[mapguide-users] Accessing Fusion commands from parent window

[Michael Adair]

In Fusion trunk, in MapguideViewerApi.js , the reference to the Fusion 
window is coded like so:

/* locate the Fusion window */
function GetFusionWindow() {
     var curWindow = window;
     while (!curWindow.Fusion) {
         if (curWindow.parent && curWindow != curWindow.parent) {
             curWindow = curWindow.parent;
         } else if(curWindow.opener) {
             curWindow = curWindow.opener;
         } else {
             alert('Could not find Fusion instance');
             break;
         }
     }
     return curWindow;
}

I would try that function to get it
