Hey Jambunathan,
I solved the bug but I cannot reach bugzilla at the moment, could you plz
close it?
The problem was that 'createZeroForCompare' returned an integer for type
Boolean. But Boolean.CompareTo(integer) is not allowed (I tested this on
MS.NET). Now 'createZeroForCompare' returns a default Boolean (false).
Greetz,
-- Rob.
