Yes, I use it as stated previously.  Is row the object you think it is?  
You either have a typo or you're trying to access properties of row that 
don't exist.

The code below shows plain html contained in a column that accesses 
properties of the current row.

<s:if test="xxxList.size > 0">
  <display:table name="xxxList" id="row">
     <s:set name="myrow" value="#attr.row"/>
     <display:column sortable="true" title="Name" property="name"/>
     <display:column sortable="true" title="Date Created" 
property="dateCreated" decorator="xxx.decorators.ShortDateDecorator"/>
     <display:column sortable="false" title="Example">
         View <a href="xxx.action?xxxId=<s:property 
value="#myrow.id"/>"><s:property value="#myrow.name"/></a>
      </display:column>
   </display:table>
</s:if>

* note there are better ways to generate an anchor in a displaytag 
table.  This is demonstrating how to access the current row using 
struts2 tags.
