John -
Not sure if Variable.findAttribute does a trim() or not on incoming
attribute names,
but if not, the extra space in "inverse_flattening " is definitely a
bug that should be
fixed. Even if benign, it should probably be changed. Full class
included below so
you can see what I mean - it's a very short file...
