 Error (translated from German) You are trying to access an entry that does no longer exist. Most probably it was deleted by another user.
 
 It seems you can only edit links to pages but not links you set to an internal document from library

Hi Markus Berchtold,
There is an already logged bug in our public issue tracking system. The bug ID is 5984. You can track it using this url:
http://www.telerik.com/support/pits.aspx#/public/sitefinity/5984
Here is a way to make your document open in a new window or edit your link to an internal document from a library:
1. Open your page
2. Edit Content block
3. Click "HTML" in order to switch to HTML editing mode
4. Now you can edit your link to an internal document
In case you want to make your document open in a new window, you have to insert target="_blank" in your <a> tag. Your HTML code will look like this:
<a sfref="..." title="..." href="..." target="_blank">my document</a>
I hope this will be helpful to you.
Best wishes,
 Miroslava

Dear Miroslava
Thanks for the detailed workaround (which of course I knew). But this is no solution for end-users so I hope to see this bug fixed in an upcomming official release.
