Subject: Re: struts2 ognl confusion
You must be using a fairly old version of Struts 2. The difference between
the ${} and the # versions is that the ${} is a JSTL EL expression that is
no longer allowed inside struts (s:) tags for security reasons. The #
version is OGNL and references the variable that Wes tried to define. Try
using the id attribute instead of the var attribute. So something more like
this:
<s:iterator value="%{questions}" status="status" id="question">
<s:if test='%{incorrectQs.contains(#question.questionId)}'>
<div style="color: red; padding-bottom: 5px;">Print Something</div>
</s:if>
</s:iterator>
I like to make it obvious which attributes use OGNL by enclosing them in %{}
