From TIBCO Spotfire version 7.13, anchor links/html bookmarks (#localref) used in Text Areas no longer work (resulting in 404 errors). This is affecting HTML and JavaScript in the text area, including JQuery.
In Spotfire 7.12 and lower (and also later versions of Analyst) the following html works, but in Web Player 7.13 and higher it does not:
<h2 id="top">Header</h2>
...lots and lots and lots of text...
<a href="#top">Jump</a>
Since the base URL is different in 7.13 and higher, the last link will jump to <base url>#top and that is a non existing page, resulting in a 404 error from the Server.
