In other words, do missing attributes evaluate to false? 2 Answers 2 Yes it will evaluate to false. EL expression specified in an attribute value is processed differently depending on the attribute's type category defined in the TLD. In core when tag, it should evaluate to boolean. In core out tag to String, etc., In your scenario, you need to have c:choose tag enclosing c:when and c:otherwise. <c:if test...
