So I've found a method that works. Perhaps it s what you were trying to
explain in the first place.
Rather than use an EL expression in the tiles definition to say which object should be used in the page title key parameter, I just define a parameter called titleKeyParam1 that the controller will optionally set directly. There is nothing about the parameters in the tiles definition file, only the titleKey.
ie.
tiles-layout.xml
<definition name="recordDetail" extends=".template"> <put name="titleKey"
value="record.detail.title"/> <put name="body" value="/WEB-INF/jsp/tiles/recordDetail.jsp"/> </definition>
jsp file <fmt:message key="${titleNameKey}"> <fmt:param><c:out
value="${titleKeyParam1}"/></fmt:param> </fmt:message>
- Then the controller optionally sets the titleKeyParam1 as an object in the
model.

btw, I've also tried this slight variation:
tiles.xml
<definition name="foo" extends=".template"> <put> name="titleKey" value="record.detail.title" type="string"/>
<put> name="titleKeyParam1" value="${recordId}" type="string"/></definition>
Which gives me the page title: "Record Detail: ${recordId}". Also giving me
the problem that it is not evaluating the expression.

This idea seems really promising, but I have been unable to implement it. Here
is what I have tried:
resource_en.properties
record.detail.title=Record Detail:{0}
tiles.xml
<definition name="foo" extends=".template"> <put
name="titleKey" value="record.detail.title"
type="string"/> <put
name="titleKeyParam1" value="recordId"
type="string"/></definition>
jsp template page
<c:set var="titleNameKey"><tiles:getAsString name="titleKey"/></c:set><c:set var="titleNameKeyParam1"><tiles:getAsString
name="titleKeyParameter1"/></c:set><fmt:message key="${titleNameKey}"> <fmt:param><c:out
value="${titleNameKeyParam1}"/></fmt:param></fmt:message>
My controller passes to the jsp view a parameter called "recordId". I know
that is working because I can use the value elsewhere.
The problem is that my title displays as: "Record Detail: recordId" instead of
showing me the value of ${recordId}
(I expected something like "Record Detail: 12345")
I've tried a few variations on this without success :-( How can I get the
title to show the value of the expression i set in my tiles definition?

you can do the same thing passing the strings keys in the tiles, then
play with the jsp pages using JSTL <fmt tag..>
<tiles:importAttribute name="titleKeyParameter1" />
<fmt:message var="parameter1Value" value="${titleKeyParameter1}"/>
<fmt:message key="foo">
<fmt:param><c:out value="${parameter1Value}"/></fmt:param>
... //repeat process....
</fmt:message>
I'm pretty sure you should be able to also put <fmt> tags within <fmt>
tags (nested), but I've never tried it.

Thats an excellent solution for the i18n part. I will change my code to use this method.
I still don't know what the best way to add variables to the title tho. I know
i can have variable placeholders in my resource file ex.
resource_en.properties
record.detail.title=Record Detail:{0}
user.detail.title=User Detail:{0}
application.title=Hello World Application
tiles.xml
<definition name="foo" extends=".template"> <put name="titleKey" value="record.detail.title"
type="string"/></definition>
jsp template page
// Somehow i need to pass in optional variables that are provided by my
controller to the title
<fmt:message key="${titleNameKey}"/>
Is this possible with tiles?
btw, sorry for posting to two mailing lists about this if thats bad form.

May I suggest to instead of using the "title" value in the tiles, use
the keys (e.g. "titleKey"), then fetched it using whatever approach you
want to:
Example:
resource_en.properties
application.title=Hello World Application
tiles.xml
<definition name="foo" extends=".template">
<put name="titleKey" value="application.title" type="string"/>
</definition>
jsp page
<c:set var="titleNameKey"><tiles:getAsString name="titleKey"/></c:set>
<fmt:message key="${titleNameKey}"/>
(of course this uses unnecessary code, but the above will work for sure)
Hope this helps!

Hi everyone,
I am running into what appears to be a limitation in tiles. I hope someone has encountered this problem before and knows of a workaround.
I have a tiles based layout that accepts a "title" in the tiles definition.
<definition name="recordDetail" extends=".template">
<put name="title" value="Record Detail"/>
<put name="body" value="/WEB-INF/jsp/tiles/recordDetail.jsp"/>
</definition>
My problem is that I need the title to be more dynamic. It needs to do two
things:
1. Support different titles depending on the locale.
2. Accept a dynamic field identifying the record number that the page is
showing.
For example, rather than say "Record Detail" like in my example it should say "Record Detail:
38847829" and in other languages it should be translated using an existing ResourceBundle (ex.
"Detalle De registro: 38847829").
My problem lies in the fact that my .template tile includes the <title> tag, but does not
know which page it is rendering. Only the "body" tile and the actual tiles
definition knows which page it is rendering for. Other pages use the same .template tile but
require different dynamic fields in their title.
Has anyone got something like this working before?
Thanks!
