Monticello error loading file : UndefinedObject(Object)>>doesNotUnderstand: #select:thenCollect: - Squeak-dev

28 Apr 2008


      I get this error when loading a mcz into Damien's 3.9.1 web image. The 
MCClassDefinition happens to be a trait, not sure if that has anything to do 
with it.
Any suggestion?
Thanks - Sophie
