Hello,
There is some mismatch in your code ;-)
First, in your <insert>, you put several time an attribute using the same name
(linknormal). Each addition overload previous value, so only the last value
remains.
Second, in your submenu.jsp, you iterate on both lists, but you do logic on
external beans, not on bean resulting from iteration.
Such external beans (novalue, linkbold, linknormal) exist because you have
imported them from tiles attribute list, and "put" them in attribute list from
<insert>.
Personally, I would create a third list, holding flags like bold, link,
separator, ... Such flags indicate what I would like to do with an item.
In submenu.jsp, I would iterate also on third list to check flag values, and
do appropriate output.
I have put the proposed code at the end. I haven't check it, so some typo
error may remain. Let us know if it works for you.
I am currently working on a new Tiles feature that will simplify such
construct. The idea is to allow to <put> or <add> a bean. You specify bean
class, and properties values. In your case, there will be 3 properties (item,
link, flag). For other menus, there could also have (img, tooltips, ...).
Menu.jsp will be also simplified because you will iterate on only one list.
Logic will apply on each iterated bean properties.

Proposed code for <insert> looks like :
<%@ taglib uri="/WEB-INF/tiles.tld" prefix="comp" %>
<comp:insert page="/hfa/common/submenu.jsp" flush="true">
<comp:put name="title" value="submenu" />
<comp:putList name="items" >
<comp:add value="Create" />
<comp:add value="Search" />
<comp:add value="Requests:" />
<comp:add value="Drafts" />
<comp:add value="In Process" />
</comp:putList>
<comp:putList name="links" >
<comp:add value="create.jsp" />
<comp:add value="search.jsp" />
<comp:add value="" />
<comp:add value="drafts.jsp" />
<comp:add value="inprocess.jsp" />
</comp:putList>
<comp:putList name="flags" >
<comp:add value="linkbold" />
<comp:add value="linknormal" />
<comp:add value="nolink" />
<comp:add value="linknormal" />
<comp:add value="linknormal" />
</comp:putList>
</comp:insert>
Tile submenu.jsp will be :
<%@ taglib uri="/WEB-INF/struts-logic.tld" prefix="logic" %>
<%@ taglib uri="/WEB-INF/struts-bean.tld" prefix="bean" %>
<%@ taglib uri="/WEB-INF/tiles.tld" prefix="comp" %>
<%@ page import="java.util.Iterator" %>
<%-- Push Tiles attributes in page context --%>
<comp:importAttribute />
<bean:define id="links" name="links" type="java.util.List" scope="page" />
<bean:define id="items" name="items" type="java.util.List" scope="page" />
<% Iterator linksIterator = links.iterator(); %>
<% Iterator itemsIterator = items.iterator(); %>
<logic:iterate id="flag" name="flags" type="java.lang.String" scope="page">
<% // Compute link value
String link = (String)linksIterator.next();
String item = (String)itemsIterator.next();
%>
<logic:equal name="flag" value="nolink">
<%=item%>
</logic:equal>
<logic:equal name="flag" value="linkbold">
<B><a href="<%=link%>"><%=item%></a></B>
</logic:equal>
<logic:equal name="flag" value="linknormal">
<a href="<%=link%>"><%=item%></a>
</logic:equal>
</logic:iterate>
