JQuery :: TreeView Cookie Persistence - JSP Directory

I'm having some issues using the cookie persistence, it appears that as long as the link is in the jsp directory the menu renders properly, however if the link is not in the jsp directory the cookie is set to null and when the page loads all of the trees are expanded.

Here is the abridged version of the file that I'm using, this is included on all pages of my application.
<div id="main"><a href=".">Main Demo</a>
<div id="sidetree">
<div class="treeheader"> </div>
<div id="sidetreecontrol"><a href="?#">Collapse All</a> | <a href="?
#">Expand All</a></div>
<ul id="tree">
<li><span>Customer Accounts</span> .....
