Subject RE: JSTL when...test won't work.
Date Thu, 02 Dec 2004 19:06:18 GMT
Well, your suggestion almost worked. I got the keys and values printed out but the "test" wouldn't
work!
Here is what I tried to do:

<c:forEach items="${fRoles}" var="item">
     <c:if test="${item.key} == 'manager'">
         Found manager
     </c:if>
</c:forEach> 

Is the syntax right?  Anyway the above code doesn't find the key manager while I can print
it out using your suggestion.

I also tried this and it didn't work...
<c:choose>
     <c:when test="${ not empty fRoles['manager']}" >
        Found formRoles manager
     </c:when>
     <c:otherwise>
        NOT Found
     </c:otherwise>
  </c:choose> 


Do you have any other suggestions?
Thanks for your help
NK

What happens when you try:

<c:forEach var="element" items="${fRoles}">
   <c:out value="Key=${element.key}, Value=${element.value}"/>
</c:forEach>

instead of logic:iterate
