Subject OgnlValueStack.logLookupFailure
Date Wed, 27 Feb 2008 19:53:46 GMT

I'm stuck with this error and have no idea what the problem is...

In my action class, I'm returning a String property called ruleType. I've
verified that it has a value of "A".

In my jsp, I have:
<s:if test="ruleType == 'A'">
   <%@include file="arithmeticDetail.jsp" %>
</s:if>

For some reason, that s:if test statement is throwing:
WARN - OgnlValueStack.logLookupFailure(269) | Caught an exception while
evaluating expression 'ruleType == 'A'' against value stack

Any ideas?
