I'm hitting this error and I'm not really sure why. I have a minified version of excanvas.js and something is breaking in IE, specifically on:
var b=a.createStyleSheet();
I'm not sure why. Does anyone have any insight? I can provide more information, I'm just not sure what information will help.
First thing I'd do is use the un-minified version. Looks like this coming from an init function called from onreadystatechange, trying to style canvas elements, although that isn't as enlightening as one might hope.
This is a slightly old thread, but I thought it would be useful to post. There seems to be a limitation on how much style information a page can contain, which causes this error in IE6. I am able to produce an invalid argument error using this simple test page:
<html>
<head>
<title></title>
<script>
for(var i=0;i<32;i++) {
document.createStyleSheet();
}
</script>
</head>
<body>
</body>
</html>
I think this is the source of the problem. HTH, Russell
The newest version of excanvas fixes this for me. You can always get the newest version from svn trunk.
