I don't believe length is even defined for Collection or List. I use size (testing > 0) and have never had a problem, but admittedly I use Rhino. And the size() method is defined as "number of elements in the list".

If you're actually saying "length" with no parentheses, pretty sure you're getting some random Javascript thing back, I didn't think Javascript auto-forwarded property names to method calls like Velocity does.
