I have a simple Kentico transformation shown below. The 'a' tag is intended to send the user back up one level in the CMS site tree. I got the single dot wildcard from Kentico documentation here <http://devnet.kentico.com/docs/5_5r2/devguide/index.html?wildcard_urls.htm>.

```
<h1><%# Eval("ArticleTitle",true) %></h1>
<div>
<%# Eval("ArticleText") %>
</div>
<p><a href='.'>Back to list</a></p>

```

The link takes me to the correct url, but is missing .aspx from the end of the url. What am I missing?
