I just noticed a difference between the struts-tiles.tld files

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE taglib PUBLIC "-//Sun Microsystems, Inc.//DTD JSP Tag Library 1.1//EN"
"http://java.sun.com/j2ee/dtds/web-jsptaglibrary_1_1.dtd";>
<taglib>
<tlibversion>1.0</tlibversion>
<jspversion>1.1</jspversion>
<shortname>Tiles Tag Library</shortname>
<uri>http://jakarta.apache.org/struts/tags-tiles-1.1</uri>
<tag>

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE taglib PUBLIC "-//Sun Microsystems, Inc.//DTD JSP Tag Library 1.1//EN"
"http://java.sun.com/j2ee/dtds/web-jsptaglibrary_1_1.dtd";>

<taglib>
<tlibversion>1.2</tlibversion>
<jspversion>1.1</jspversion>
<shortname>tiles</shortname>
<uri>http://struts.apache.org/tags-tiles</uri>
<tag>


Does anyone know where to find info as to what I need to do to updrage to the latest version tlibversion?

useAttribute is in struts-tiles.tld...still no luck. This is frustrating because it is from the example that comes with Tiles. Does anybody know of any IDE's that allow you to step thru JSP code?

...this is vboxLayout.jsp,

<%@ page import="java.util.Iterator"%>
<%@ taglib uri="/WEB-INF/struts-tiles.tld" prefix="tiles" %>

<%-- Layout component
 Render a list of tiles in a vertical column
 @param : list List of names to insert

--%>

<tiles:useAttribute id="list" name="list" classname="java.util.List" />

<%-- Iterate over names.
 We don't use <iterate> tag because it doesn't allow insert (in JSP1.1)
--%>
<%
Iterator i=list.iterator();
while( i.hasNext() )
 {
 String name= (String)i.next();
%>
<tiles:insert name="<%=name%>" flush="true" />
<br>

<%
 } // end loop
%>





...this is columnsLayout.jsp,

<%@ page import="org.apache.struts.tiles.ComponentContext"%>
<%@ taglib uri="/WEB-INF/struts-tiles.tld" prefix="tiles" %>

<%-- Layout component
 Render a list on severals columns
 parameters : numCols, list0, list1, list2, list3, ...
--%>

<tiles:useAttribute id="numColsStr" name="numCols" classname="java.lang.String" />


<table>
<tr>
<%
int numCols = Integer.parseInt(numColsStr);
ComponentContext context = ComponentContext.getContext( request );
for( int i=0; i<numCols; i++ )
 {
 java.util.List list=(java.util.List)context.getAttribute( "list" + i );
 pageContext.setAttribute("list", list );
 if(list==null)
   System.out.println( "list is null for " + i  );
%>
<td valign="top">
 <tiles:insert page="/common/layouts/vboxLayout.jsp" flush="true" >
   <tiles:put name="componentsList" beanName="list" beanScope="page" />
 </tiles:insert>
</td>
<%
 } // end loop
%>
</tr>
</table>


This is the error...

It simply says it can't find tile definition referenced by "name" attribute of
your "useAttribute" tag. Try to check out if your tiles definitions.
