David,
I'm not sure if there's a way to do exactly what you're asking but I can
suggest another way that I've used.
With a preparer you might do something this:
Put an place-holder string into the tiles configuration like so:
<put-attribute name="title_page_name" value="Sales
[SALES_RATES_SERVICE_TYPE] Rates" /> </definition>
Wire up a preparer for the definition:
<definition name="SalesRates_application.layout"
extends="general.logon.layout"
preparer="com.claytonrabenda.awesometitlepreparer">
In the preparer, grab the attribute and replace the string:
String theTitle = (String)
attributeContext.getAttribute("title_page_name").getValue();
//Do replacement here using session
attributeContext.putAttribute("title", new Attribute(theTitle));
Hope this helps!

Subject: Session Attribute in Tiles Definition
Is it possible to add attributes from the session to the put attribute
of a tiles definition. I would like to do something like...
<definition name="SalesRates_application.layout"
extends="general.logon.layout">
<put-attribute name="title_page_name" value="Sales
${sessonScope.SALES_RATES_SERVICE_TYPE} Rates" /> </definition>
What do I need to setup to allow the expression language to be able to
parse the session attribute. Can Struts 2 expressions such as
%{#session.SALES_RATES_SERVICE_TYPE} also be used?
The expression language support page on the tiles web site has the
example
<definition name="test.composite.el.definition"
templateExpression="${layout}"
preparer="org.apache.tiles.test.preparer.RequestSettingViewPreparer">
<put-attribute name="title" value="This is a configured composite
definition."/>
<put-attribute name="header" value="/header.jsp"/>
<put-attribute name="body" expression="${requestScope.body}"/>
</definition>
Where does the templateExpression= and expression= attributes come from?
I don't see them defined in the tiles reference sheet.
David Smith
