You're welcome, although for the record, I was wrong again. :) After finally looking at the docs myself, it *does* say that you should be able to use your collection in notEmpty. I didn't remember this, obviously. And it does say that it will check for an empty collection. I suppose using <bean:define> to get your collection into a variable, then use that as the name attribute of the notEmpty tag, would be what I might try.
However, glad you got it working!
