You could just throw in the <c:forEach> loop; in Beta 1, if your
collection doesn't contain any items, the loop will simply skip over it.
By the way, what, exactly, do you mean by "standardized method of getting
the number of objects without having to go through a <c:forEach>". Are
you suggesting that there should be some way to call size() for an object
in the Collections framework, or something more general? And does
<c:forEach>'s new, "collapsible" behavior ("simply don't iterate if
nothing's there") address this issue for you?
