I think you should be able to reference the MapGuideViewerAPI.js script from your aspx page, and then just call DigitizePoint directly without any window.top or parent references.
It should also be possible to add a reference to MapGuideViewerAPI.js to the index.html file in the Fusion template you're using, and reference it using window.top... It's been a while since I've played around with this stuff, so someone else may be able to provide specifics...

In both AJAX and FUSION I'm working from the taskpane and using the markup scripts that are part of the AJAX demo's and tutorials. I assume I need to substitute either 'Fusion' or 'window.top.Fusion' somehow for 'parent.parent.parent.mapFrame.DigitizePoint(OnPointDigitized);'. in my script however I have yet to do this in such a way that it works. I keep getting 'Object doesn't support this property or method'. So for example in my editmarkup.aspx code for example, I have the following function which should be activated when I click the digitize point button function AddPoint() { SetDigitizeInfo(EDIT_POINT_HELP); parent.parent.parent.mapFrame.DigitizePoint(OnPointDigitized); } In Fusion this code gives an error 'parent.parent,parent.mapFrame' is null or not an object I see that in MapGuideViewerAPI.js function DigitizePoint(handler) { if (handler) { var Fusion = window.top.Fusion; var mapWidget = Fusion.getWidgetById(mapWidgetId); var digitizer = new Fusion.Tool.Canvas.Point(mapWidget); digitizer.mouseUp = PointHandlers.prototype.mouseUp; Object.inheritFrom(digitizer, Fusion.Tool.Canvas.prototype, []); digitizer.initializeCanvas(); var activeWidget = mapWidget.buttonSet.activeButton; mapWidget.buttonSet.setActiveButton(null); digitizer.handler = function() { handler.apply(null, arguments); activeWidget.setActive(true); } digitizer.activateCanvas(); //add a listener to update the position of the features var mapWidget = Fusion.getWidgetById(mapWidgetId); mapWidget.registerForEvent(Fusion.Event.MAP_EXTENTS_CHANGED, function(){ digitizer.updatePx(); digitizer.clearContext(); digitizer.draw(digitizer.context); } ); } } Thanks Fraser
