I am new to Smalltalk and Squeak and am having some trouble using the 3.8.1version of the Squeak Workspace. I originally wrote the following:
x := OrderedCollection new. x add: 'blue'. x do: [:a | Transcript show: a; cr] This works fine. I then changed it to this: x := Collection new. x add: 'blue'. x do: [:a | Transcript show: a; cr] Which produced an error on Collcetion>>add: as a subclass Responsibility which seems correct. But when I change it back to OrderedCollection I get an error that Collection>>do: is subclass responsibility. However this is EXACTLY the same code as before that worked. But now I have to exit the Workspace and start another before the code works again. Am I doing something wrong? Brent
