Subject Re: c:forEach does not recognize HashSet when combined with nested EL ?
Date Tue, 01 Nov 2005 18:11:00 GMT
You need to tell your loop to use the key or the value from your set.

<c:forEach var="paymentDetails" items="${studentEnrollment.paymentDetails}">
  <c:out value='{paymentDetails.key}'/>
  <c:out value='{paymentDetails.value}'/>
</c:forEach>
...

that should fix it up.
