How to use the JSTL "if" tag without getting "..attribute test does not accept any expressions"

Question

Hi, I've been googling around for quite some time now and I've decided to ask this here, how would I make the following code work?

        <c:if test="${null != searchResults}" >
            <c:forEach items="${searchResults}" var="result" varStatus="status">

I've tried many different variations of this, such as:

<c:if test="${searchWasPerformed}" >

or

<c:if test="<%=request.getAttribute("searchWasPerformed") %>" >

and even

<% boolean b = null != request.getAttribute("searchResults"); %>
    <c:if test="${b}" >

Which looks REALLY ugly :/ But I keep on getting the

org.apache.jasper.JasperException: /WEB-INF/jsp/admin/admin-index.jsp(29,2) PWC6236: According to TLD or attribute directive in tag file, attribute test does not accept any expressions

My question is, how would I go around this?

Thanks in advance! Erik

Check version of JSTL taglib you use. It should be 1.1, so you should have (note the URI):

<%@ taglib prefix = "c" uri = "http://java.sun.com/jsp/jstl/core" %>
