JSTL and Struts Tags
I haven't been successful with using the <c:set> tag and using this
output value within a Stuts tag.
The variable "engineTest" (below) does not seem to output correctly as
a boolean value to the <html:multibox> tag. However, as a test, I can
succesfully use the scriptlet variable "val" which invokes the disable
attribute correctly.
I have also tried: ${Boolean.TRUE.booleanValue} with no luck.
Should I be able to do this or should use the tried and true scriptlets?
Example:
<% boolean val = false%>
<c:forEach begin="0" end="3"
items='${saveUserPreferences.map.searchEngines}' var='engine'>
<c:if test="${engine.active == 0}">
<c:set var="engineTest" value="${true}"/>
<% val = true;%>
</c:if>
<%--disable attribute not invoked--%>
<html:multibox disabled="${engineTest}" property="userSearchEngines">
<c:out value='${engine.id}' />
</html:multibox>
<c:out value='${engine.name}' /> <c:out
value='${engine.description}' />
<%--works correctly--%>
<html:multibox disabled="<%=val%>" property="userSearchEngines">
<c:out value='${engine.id}' />
</html:multibox>
<c:out value='${engine.name}' /> <c:out
value='${engine.description}' />
<br/>
</c:forEach>

Hi Bill,
Make sure you have activated El evaluation. My suggestion: add "<%@
page isELIgnored="false"%>" on top of your JSP file. This precedes any
settings in the web.xml file
BTW, this <c:set.../> script is OK, at least it works on my machine.
