Comment #1 on issue 726 by tudor.gi...@gmail.com: FM3PropertyDescription>>getRawFrom: should return false in Boolean properties instead of nil http://code.google.com/p/moose-technology/issues/detail?id=726
getRawFrom: is basic and must remain like this because it is used in many contexts. The metanool-related problem should probably be solved in metanool when installing the property.
