Hi,
If you try any of the samples in ASP.NET download (3.6.4), clicking the the TextColor and BGColor toolbar items generate script errors. Try for example try SampleConfig.aspx.
Script error is: Line: 126
Error: Unable to get property 'body' of undefined or null reference
I get the same when inserting a CKEdit control in my aspx page. I tried to just load one toolbar item, TextColor, still the same error.
Anyone knows what this is about?

This is happening to me too
I am using IE10. Has anyone found a solution to this?
Javascript error in ASP.Net
I'm using CKEditor 3.6.4 for ASP.Net. The custom toolbar entries for TextColor and BGColor yield a javascript error of:
Line: 126
Error: Unable to get property 'body' of undefined or null reference
I am using IE10. Can anyone help?
I'm having the same problem,
I'm having the same problem, NeilMcK's message describes mine exactly.
Hack - but works
This is tested on IE 10 and FF 26.0
At the exception, you'll see: if(c)G=G.document.body; (This is in ckeditor.js, line 126 @char 363 in my version)
I changed this to: if (c && G.document)G=G.document.body;
The markup produced is correct and the end product looks fine.
Please note this is just for a backend system, so in my case this is an acceptable hack.
