Is it possible to compare 2 variables in Struts IF statement when one of variables is from <c:foreach>?

问题

I'm trying to compare attribute value with some value passed from <c:foreach> to <s:if> and it always is false (even though it shouldn't).

<c:forEach items="${liveBuyRequestsId}" var="item">

<s:if test="%{#attr.documentRow.buyRequest.id == item}"> The value of item is Long, same should be for id.

What am I doing wrong?
