I would like to use EL in tiles definitions. Is it supported by Struts 2.x

little fact finding before performing open heart surgery on my working

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>
</h1>
