Errors in IE for Windows Phone

[sirtwist]

I'm getting the following errors for RadEditor in IE for Windows Phone, but not on any other platform as far as I can tell:

Error while executing filter FixUIBoldItalic - TypeError: Unable to get property 'getElementsByTagName of undefined or null reference

and

Error while executing filter ConvertFontToSpanFilter - TypeError: Unable to get property 'ownerDocument' of undefined or null reference

Thoughts?

Hello,

Could you please give me the following information:

1. First, could you confirm that you are using the latest version of our controls(currently Q3 SP1 2014). Older versions might not contain the fixes for IE11.
2. Test the behavior on our demo so that we could isolate the issue.
3. Currently, due to the Christmas holidays I could test the behavior only on Microsoft Surface and Nokia Lumia and I couldn't manage to reproduce the issue. What device are you using?

For the time being you could disable these filters by adding the following code:

protected void Page_Load(object sender, EventArgs e)
{
    RadEditor1.DisableFilter(Telerik.Web.UI.EditorFilters.FixUlBoldItalic);
    RadEditor1.DisableFilter(Telerik.Web.UI.EditorFilters.ConvertFontToSpan);
}

Joana,

Thanks for the reply. Yes, I'm running the latest version of the controls. The same errors pop up on your demo. The device is a Nokia Lumia 1020 running Windows Phone 8.1.1 with IE11.

Also, to be clear, these errors do NOT appear in IE11 on full-fledged Windows 8.1 (neither desktop IE nor modern IE). Tested on a Surface Pro 3 with no issues. I've only seen the errors on IE11 on Windows Phone.

Also, to be clear, this appears to only happen on IE11 for Windows Phone, not IE11 on desktop/tablet Windows. Tested on Surface Pro 3 with Windows 8.1 Update with no issues.

Hello,

Thank you for the additional details.

On our end, we are still unable to reproduce the described issues.

Could you please verify if the issue is reproducible with the online demo (RadEditor - Overview), as Joana asked in her post?

The matter might be also related to the content used, so can you please provide a sample content that leads to the same behavior?

Also, are you able to resolve the issues by disabling the filters?

As I stated in my previous message, yes, the same exact error messages happen on your demo.

As far as the issue being content-related, that's simply not the case. The errors come up immediately upon page load, with no content in the editor at all.

As far as replicating the issue, I was able to replicate it using BrowserStacks with Windows Phone/Lumia 930, so it's not just my phone. :) 

I haven't tried disabling the filters yet because I actually want the filters enabled. :)

Hi,

Indeed, the issue bug exists. We were able to reproduce it on our end using the same device. 

I logged this bug report and created this feedback portal item for you to follow the progress on the task. 

As appreciation for reporting this issue, I am updating your Telerik points.

I am afraid that the only possible workaround available at the moment is disabling the filters. Once a more reliable solution is available, it will be added as information in the feedback portal
