[fusion-users] MapGuide Ent 2010: Fusion and digitize error

[Paul Spencer]

Ah I see the problem now.  CanvasTool is designed as a mixin class for  
widgets to provide client-side rendering services.  Each widget  
provides a getMap method which is available to the CanvasTool  
methods.  When CanvasTool is used by the MapGuideViewerApi.js methods,  
it is created directly (not as a mixin for Widget) and hence has no  
getMap() method.

In MapGuideViewerApi.js in fusion distributed with MGOS 2.1 beta  
around line 176, there is this:

Fusion.Tool.Canvas.prototype.getMap = function() {
   return Fusion.getWidgetById(mapWidgetId);
}

which should, theoretically, be doing the same thing you are doing by  
modifying CanvasTool.js directly.  Does the version you have include  
this definition?  If not, can you try adding the above to  
MapGuideViewerApi.js (anywhere will do) and removing your change to  
CanvasTool.js and see if it still works?

Cheers

Paul
