[ka-Map-users] img.onload bug within IE?

[Wei Yang, Ng - Wayne]

Hi Pg,
    I was wondering if you are aware of icons not getting drawn with 
kaXmlOverlay. This only happens within Internet Explorer and the problem 
is intermittent. Sometimes, while trying to draw many icons (20-50 or 
even 100), not all of them appeared. Apparently, if we look at the 
"kaXmlIcon.prototype.draw_canvas" function, there is this line where you 
specify an "img.onload" event. I did some tests and found that this 
event is not always being triggered which is why the "ctx.drawImage" 
function does not always get called. My website runs over https.

Changing this:
this.img.onload = function() {
        ctx.drawImage(timg, dx, dy, tw, th);
        ctx.restore();
}
to this:
        ctx.drawImage(timg, dx, dy, tw, th);
        ctx.restore();

seems to make it work fine now.

Cheers,
Wayne
