Using if in JSP

Question

I am trying to use an if condition to display an item or not in one of my JSP files.

I currently have

<c:if test="${fn:length(${model.listOfListProducts}) gt 0}">
<p> we got in </p>
</c:if>

I am trying to see if the length of one of my Lists< List<>> in my model object is essentially greater than 0 (not null)

But this does not display the paragraph that I have placed inside. Is my test statement syntactically wrong?

What is `model.listOfListProducts`? – Elliott Frisch Jul 23 '14 at 22:12 — Elliott Frisch, Jul 23 '14 at 22:12

remove $ from nested expression

<c:if test="${fn:length(model.listOfListProducts) gt 0}">
  <p> we got in </p>
</c:if>
