Struts 2 and Tiles 2.1.0
I would like to use EL in tiles definitions. Is it supported by Struts 2.x
and is there a recipe for this? I downloaded Tiles 2.1.0 and reviewed the
changes, but the web.xml has undergone radical change and I thought I'd do a
little fact finding before performing open heart surgery on my working
application.
Peace,
Scott

Thanks Adam --
I looked at this option, but would rather use EL in tiles definitions. It
would be a much cleaner (and intuitive) solution.

Hi Scott,
not directly in tiles.xml, however with just one more step, it's easy. This is
the approach I took.
Tiles.xml definition:
<definition name="collatedAnalysisInsert.tile"
extends="collatedAnalysisList.tile">
<put-attribute name="tilesSubmitAction" value="collated-analysis/new" />
<put-attribute name="bodyContentTile"
value="/WEB-INF/jsp/collated-analysis/edit.jsp" />
<put-attribute name="tilesContextHeader"
value="collatedanalysis.insert.pageHeader" />
<put-attribute name="tilesAdditionalTitle" type="string"
value="collatedRun.portfolio.title" />
</definition>
Sorry it's a bit of dry example. The last attribute 'tilesAdditionalTitle' is
actually the reference to a javabean object with nested objects found in the
requestAttributes, but as far as tiles is concerned, it's just a string attribute.
In the JSP, I can retrieve it from the requestAttributes using the JSTL
requestScope[] map. I use it like this:
<tiles:importAttribute />
<h1 class="contextHeader">
<fmt:message key="${tilesContextHeader}">
<c:if test="${!empty tilesAdditionalTitle}">
<fmt:param value="${requestScope[tilesAdditionalTitle]}" />
</c:if>
</fmt:message>

Fantastic! But then why don't you write to Tiles Developers list?

It could easily be either one at this point! Rather than just complain
about the docs, I'd like to offer corrective criticism and volunteer to tidy
them up myself once this is resolved. I think the localePatternPaths was
empty, but will verify when I get to St. Louis today.

This might be the problem. Can you see ifthe localePatternPaths map is
filled or not?
Because if it is filled then it is a problem of evaluation, otherwise
a problem of initialization.

I simply don't know, it might be a bug. For this reason I asked you to
try without Struts, to see if it is a Struts Tiles plugin bug or a
Tiles bug.

If I have this tiles definition

why is this definition request not found?

It is Struts 2 that strips the URL. In your case, Tiles is called only
when the definition:
myapp.tile{1}.titleFred Title
is called. The substitution of {1} is done by Struts 2 (because it is
a Struts result). But the matching with the wildcard-based definition
is done by Tiles.
The definition is created at runtime once if it is not present (it
will be reused if it has been already created).

Probably it was for Tiles 2.0, can you link it?

First Struts 2 matches the URL and substitutes in the result.
Then Tiles 2 is called, matches the definition and substitute the
placeholders in attributes and template.

Just as a reminder, for questions about the development of Struts
contact the Struts developers mailing list:

Thanks brother --
I could not tell if this was the case or if I had things wired up wrong. I
added the optional jars as per the Tiles/2 setup and nearly have the EL
working with the existing Struts 2.1 Tiles plugin. I was a little confused
about "If you insert a definition that matches the definition, for
example:" in this doc
http://tiles.apache.org/framework/tutorial/advanced/wildcard.html
Does Tiles/2 strip the URL and construct a "realtime" definition from a
request or do you have to get involved in the life-cycle processing? I read
another article where you had suggested a view preparer??? I guess I'm a
little unclear on what the framework is doing with these substitutions.
If you can clear it up for me and additional code needs to be written, I'd
be happy to work on modifying the S2 plug-in.
Peace,

Sorry I forgot to complete the sentense :-D
I think that Struts2/Tiles2 plugin does not create/assign the wildcard
matcher, or some dependency is not resolved at all.
Try using Tiles 2.1 alone.

Probably Struts 2 is not configured correctly, because the
Struts2/Tiles2 plugin does not work with Tiles 2.1. I think that
Did you try using Tiles 2.1 alone?
Antonio
Re: Struts 2 and Tiles 2.1.0
Posted by stanlick <st...@gmail.com>.
Okay, I nearly have things wired together! I read, stitched and read some
more and sort of have things working. However, when I attempt to leverage a
wildcard definition, I receive the following message:
12:03:09,571 DEBUG org.apache.tiles.impl.BasicTilesContainer.render():384 -
Render request recieved for definition 'myapp.tilecore.titleFred Title'
12:03:09,587 WARN org.apache.tiles.impl.BasicTilesContainer.render():392 -
Unable to find the definition 'myapp.tilecore.titleFred Title'
My tiles definition is as follows:
<definition name="myapp.tile*.title*" extends="myapp.homePage">
<put-attribute name="content" value="{1}"/>
<put-attribute name="title" value="{2}"/>
</definition>
And here is the Struts action mapping:
<action name="tile-*">
<result>myapp.tile{1}.titleFred Title</result>
</action>
Any idea what might be going on?
Peace,
Scott

Actually, S2 wraps the request object and translates EL syntax into OGNL
stack.find.
P.S. Tiles 2.1 looks wicked cool!

Wait a minute: Struts 2 does not support EL in its JSP tags, but Tiles
2.1 supports EL both in JSP tags (also for Tiles 2.0) and in Tiles
definitions:
