I have the following definition:

<definition name="pageLayout" path="/layouts/pageLayout.jsp">
        <putList name="screenStyles">
            <add value="/styles/page.css"/>
            <add value="/styles/bluegray.css"/>
         </putList>
</definition>

Then in my pageLayout.jsp, I use the following to print out the stylesheets
associated with a page:

  <style type="text/css" media="screen">
        <tiles:useAttribute id="screenList" name="screenStyles"
classname="java.util.List" />
        <c:forEach var="stylesheet" items="${screenList}">
            @import url(<%=request.getContextPath()%><c:out
value="${stylesheet}"/>);
        </c:forEach>
  </style>

This all works great.  The enhancement I want to make is to define the
different putList's so I can have "blueTheme" and "orangeTheme" as a
definition.

The reason is thus - if I want to override the list of stylesheets in a page
that extends pageLayout, I have to add the full list again, thusly:

 <definition name="page.tools" extends="pageLayout">
  <put name="title.key" value="tools.title"/>
  <put name="heading.key" value="tools.heading"/>
  <put name="content" value="/viewer/tools.jsp"/>
        <putList name="screenStyles">
            <add value="/styles/page.css"/>
            <add value="/styles/orangegray.css"/>
  </putList>
 </definition>

I'd like to have the following:

<definition name="blueTheme">
        <putList name="screenStyles">
            <add value="/styles/page.css"/>
            <add value="/styles/bluegray.css"/>
         </putList>
</definition>

and then I could just change the "page.tools" definition to:

 <definition name="page.tools" extends="pageLayout">
  <put name="title.key" value="tools.title"/>
  <put name="heading.key" value="tools.heading"/>
  <put name="content" value="/viewer/tools.jsp"/>
  <put name="screenStyles" value="blueTheme"/>
 </definition>

However, this doesn't work.  I'd tell you my error - but since my errorPage
extends pageLayout - I end up in an infinite loop :(

Thanks,

Matt
