Unfortunately, our developers were not able to fix the problem in time for the release. The bug turned out to be a browser specific issue. When you enter the above content in IE, it converts it internally to the following:
|<LI>The ul tags around this produce the effect</LI></UL>This text gets repeated <A href="http://www.telerik.com/">this link doesn't</A>.</SPAN> |
As you can see, the content is no longer valid HTML. Our MOSS and SharePoint editors are set to produce XHTML content (the ConvertToXhtml property is set to True). When the invalid content goes through the XHTML filter, there is some unexpected behavior (in this case text is duplicated). If we switch off the ConvertToXhtml filter, the text is not duplicated. However, the HTML is still invalid. We experimented using the same content and other WYSIWYG editors, and noticed the exact same problem (which is normal, since the bug is browser related).
In order to stop the text duplication, you must turn off the ConvertToXhtml filter from the editor's configuration file. The editor content will still be XHTML, since we have a second filter on the server. The ConvertToXhtml filter is only enabled on the client.
All the best,
the Telerik team
