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.
