The body of <jsp:useBean> is only processed the first time the bean is created.
Outside loop:
<jsp:useBean id="paramMap" class="java.util.HashMap"/>
Inside loop:
<c:set target="${paramMap}"
property="pageName" value="${topMenuItem.menuItemName}"/>
<c:set target="${paramMap}"
property="menuBlock" value="${topMenuItem.link}"/>
