I would try to fiddle around with incorrectQs to see why .contains
isn't working... I'm guessing that if you iterate both lists, although
not efficient, you might get better results -
<s:iterator value="questions" id="question">
<s:iterator value="incorrectQs" id="incorrectQ">
<s:if test='%{#incorrectQ == #question.questionId}'>
<div style="color: red; padding-bottom: 5px;">Print Something</div>
</s:if>
</s:iterator>
</s:iterator>
