[displaytag-user] Can id property of table be a runtime expression

[Randy Shelley]

I am getting the following error:
 
      [ServletException in:/WEB-INF/src/jsp/dyna/searchDynaTableData.jsp] null' 

 with the following in my JSP
 
<logic:iterate name="SearchDynaTableDataForm" property="results" id="element" 
type="Vector" scope="request">
    <display:table name="pageScope.element" export="true" id="<%="row%>" 
requestURI="SearchDynaTableDataAction.do" pagesize="10" class="display">
       <display:column sortable="true"  title="var1" property="var1" 
headerClass="sortable"></display:column>
      <display:column sortable="true"  title="var2" property="var2" 
headerClass="sortable" ></display:column>
    </display:table>
</logic:iterate>
 
if I do id="row" it works fine.
 
The reson I need a runtime expression is that I will be listing a dynamic list of 
multiple tables and I need to change id for each table to do the sort properly. The 
displaytag tld says that a runtime expression is true. What is going on?
