How come:

[jan-helge . bergesen]

                <echo>${all_fail} div ${total_test}</echo>
                <echo><j:expr value="${all_fail div total_test}"/></echo>
Yields:
    [echo] 5 div 107
    [echo]

I.e.: the output of the j:expr is an empty string?

I'd expect something like 0.0467 - am I wrong?
