[mapguide-users] fusion and javascript

[Paul Spencer]

I'm not using the viewer api thing but I can confirm that having a  
comma after the last thing in an object declaration or array is not  
valid for IE (but firefox silently ignores it).

Not sure about the var Fusion thing, but that seems reasonable since  
the task pane runs inside an iframe which is a separate document and  
doesn't automatically have references to its containing page variable  
namespace.

It has just occurred to me that this might work better if you don't  
include the MapGuideViewerAPI.js in your task page but rather include  
it in your main index page and then reference its functions through  
window.top ???  Then you wouldn't need to include the javascript files  
in your task page - i.e. use window.top.DigitizePoint()

Cheers

Paul
