Chart issue in IE8 VMLRenderer

by **rjivan** on Wed Jul 28, 2010 6:35 pm

I have been getting spradic errrors in IE8 when rendered a chart. The error I get is

Code: Select all: Message: Unspecified error. Line: 88 Char: 448 Code: 0 URI: http://localhost/highcharts/2.0.1/js/highcharts.js?a

Tracking this in the uncompressed code I see the error is coming from the function VMLRenderer on line 2696

Code: Select all: if (!doc.namespaces.hcv)

I seems like doc.namespaces has not been defined when this function was invoked. I found this post on the openlayers group

Microsoft's documentation does not say when
document.namespaces is ready, but all our OpenLayers examples use an
init function, which is bound to document.onload, because we know that
document.namespaces is available at the time document.onload is fired.

Is this something that can be addressed fairly quickly?

Thanks

As it is an issue of highcharts internals, we have to wait for Torstein to fix it. He's off-line till Monday.
There are many problems with VMLRenderer all the time. I'm sure we all know what the dealing with JavaScript in IE means for developers :)
Thanks for reporting, anyway :)

FYI..
Adding

Code: Select all: xmlns:v=urn:schemas-microsoft-com:vml

to the HTML tag seems to have fixed the issue. For exampe

Code: Select all: <html xmlns="http://www.w3.org/1999/xhtml" xmlns:v=urn:schemas-microsoft-com:vml xml:lang="en" lang="en">

Wow, great catch on the fix. I hope there's a "better" fix forthcoming, but for now, this is great. Thanks!

Thanks for the report and the workaroun. Another workaround is to add the chart on window.load. See http://github.com/highslide-software/hi ... /#issue/34.
