I still don't know what caused the issue.  Using just the <a> tag
revealed that  ${companyId} was null, producting <a href=""> tags.
So I removed the id from the <s:url> tag... and then embedded the the
whole <s:url> tag into the <a> tag, and it works as expected...

<a href='<s:url action="companyDetails.action"
namespace="/secure"><s:param name="group"
value="log.id.mlgroup"/><s:param name="id"
value="log.id.mlid"/></s:url>'>
   <s:property value="cur.mco"/>
</a>

My issue is it isn't pretty. Okay just out of interest I added
id="something" to <s:url> and the html is back to <a href=''>... So the
id attribute causes the tag not to return a value and pushes the url
onto the value stack as the name of the id attribute?  

The usage example here suggests this too:

Use the &quot;href&quot; not the &quot;value&quot; attribute to specify the URL.

Unless you are use the tag ajax support there is no reason to use the
&lt;s:a&gt; tag just use the plain html &lt;a&gt; tag

like &lt;a href=&quot;${companyId}&quot;&gt;
