wildcards
Are wildcards allowed in the extends attribute of a tiles definition?
Using tiles 2.1.3 with struts 2.0.14
Started with
<definition name="sales_rates_application.layout"
extends="general.logon.layout">
<put-attribute name="title_page_name" value="Sales Rates" />
</definition>
<definition name="sales_rates_kickoff.page"
extends="sales_rates_application.layout">
<put-attribute name="body"
value="/pages/sales_rates/sales_rates_kickoff.jsp" />
</definition>
Added wildcards to the body. This works
<definition name="*_kickoff.page"
extends="sales_rates_application.layout">
<put-attribute name="body"
value="/pages/{1}/{1}_kickoff.jsp" />
</definition>
Added wildcard to extends. This doesn't work.
<definition name="*_kickoff.page"
extends="{1}_application.layout">
<put-attribute name="body"
value="/pages/{1}/{1}_kickoff.jsp" />
</definition>

The parent should be considered a half-filled template.
However, I changed my mind. It is difficult to do, but not impossible,
the wildcard-based definitions should be evaluated and resolved only
when requested.

Yet you can have a wildcard in the template definition. Isn't the parent
just an extension of the template.
Example from the tiles web site.
the wildcard-based style (available by default):
<definition name="test.definition*.message*" template="/layout{1}.jsp">
<put-attribute name="title" value="This definition has a message:
{2}."/>
<put-attribute name="header" value="/header.jsp"/>
<put-attribute name="body" value="/body.jsp"/>
</definition>

No. This for two reasons.
The first is technical: since, historically, Tiles loads all the
definitions and resolves all inheritance at load time, it's impossible
to do a search for an "unresolved" parent definition. This problem,
however, can be overcome using a non-resolving technique, that is
potentially slower.
The second is about design: does it make sense to have a dynamic
parent definition?

Just a note, see inside:

The above works, but this not:
<definition name="*_application.layout"
extends="general.logon.layout">
<put-attribute name="title_page_name" value="Sales Rates" />
</definition>
<definition name="*_kickoff.page"
extends="sales_rates_application.layout">
<put-attribute name="body"
value="/pages/{1}/{1}_kickoff.jsp" />
</definition>
This because Tiles tries to resolve a parent definition when loading a
wildcard-based definition, that does not find.

RE: Session Attribute in Tiles Definition
Posted by "Smith, David W" <da...@bankofamerica.com>.
Thanks Clayton. Adding a preparer worked.
It seems like Tiles should be able to do this for you so that you don't
have to a create special preparer just to insert a value from the
session or the request into an attribute.

RE: Session Attribute in Tiles Definition

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!

Is it possible to add attributes from the session to the put attribute

<definition name="SalesRates_application.layout"

<put-attribute name="title_page_name" value="Sales

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.

Ok, then you should be able to use EL in all Tiles tags.
But in this case remember that expressions are evaluated at "put
time", not at "rendering time".
If you want expression evaluation, you need Tiles 2.2.0 (still in
alpha stage) where you can use:
<tiles:put expression="..." />
where the expression can be EL. Notice that this must be a string!!!
This means that you have to compose a string in a way it does not get
evaluated, such as:
${'$' + '{mybean'}'}
You can also use OGNL or MVEL.
The syntax is the same as the one for the definition files:

First of all, what version of Tiles are you using? The answer depends on this.
