Tiles 2.1.4 /Struts 2.2.3 / EL Expressions

[Jose Luis Martinez Avial <jl...@pb-santander.com>]

Hi,

                I'm using Struts 2.2.3 with Tiles 2.1.4. It works
absolutely fine, but now I'm trying to use EL expressions, and I can't
get it to work. In Struts2 I can  use <s:property
value="${getText('Dashboard.label')}"/> and it retrieves the message
from a bundle. I'd like to use the same on the Tiles Definition. So far
I've added the context-param to the web.xml

 

       <context-param>

 
<param-name>org.apache.tiles.evaluator.AttributeEvaluator</param-name>

 
<param-value>org.apache.tiles.evaluator.el.ELAttributeEvaluator</param-v
alue>

       </context-param>

 

                Now I want to use the following expression on the
definition:

       

       <put-attribute name="pane-title"
expression="${getText('Dashboard.label')}" cascade="true"/>

              

                The issue is that when I do this, the screen fails to be
created saying:

 

                Function ':getText' not found

 

                So I suppose I'm missing something, but I don't know
why. Any ideas?

 

Thanks

 

JL

That the solution I used. It's just that the title in some screens is
just a i18n string, which I wanted to define simply as 

<put-attribute name="pane-title"
expression="${getText('Dashboard.label')}" cascade="true"/>

And in some other cases the tile would be a JSP, so I could use:

<put-attribute name="pane-title" value="/WEB-INF/jsp/my-title.jsp"
cascade="true"/>

And the template would look for the value of the expression or just
insert the JSP. What I've done is create a little JSP that can used for
that, so I add the following attributes to the definition

<put-attribute name="pane-title"
value="/WEB-INF/jsp/pane-title-text.jsp" cascade="true"/>
<put-attribute name="pane-title-key" value="Dashboard.label"
cascade="true"/>

And in pane-title-text.jsp:

<%@taglib prefix="s"     uri="/struts-tags" %>
<%@taglib prefix="tiles" uri="http://tiles.apache.org/tags-tiles" %>
<tiles:importAttribute name="pane-title-key" />
<s:text name="%{#attr['pane-title-key']}"/>

And it works just fine. So I will use that, unless somebody has a better
idea.

Thanks 

JL

I am not absolutely sure, but I suppose that getText is a private EL
function of Struts 2. Since Tiles  is not Struts 2, there is no way to
use it.
Only standard EL expressions are available.
Anyway, instead of doing a "put-attribute" of the title itself, do a
"put-attribute" of the title key, import the attribute and then use
<s:property> to retrieve the value from the bundle.
