[Struts 2] If exists tag?
Hello:
Is there a struts tag to check if a collection is not null
and has at least one element?
I want to check a collection before printing the table
containing the elements using an <s:iterator> tag.
Thanks,
Neil

<s:if test="collection != null && !collection.isEmpty">
...
</s:if>

isEmpty is a "pseudo-property" of every collection, so there's no reason
to call it as a method().
