This change breaks the undo/redo mechanism of class definitions and subsequently the undo/redo mechanism of all other code changes and refactorings.
And from:
OBTextMorphWithShout >> editorClass    "Answer the class used to create the receiver's editor"
   ^OBTextMorphEditorWithShout
to:
OBTextMorphWithShout >> editorClass    "Answer the class used to create the receiver's editor"
   ^SmalltalkEditor
This breaks OB in various ways. Not every editor is a Smalltalk editor, there are lots of editors that don't need Smalltalk semantics (editing comments, editing organization, displaying lint results, displaying diffs, ...). Furthermore, OBTextMorphWithShould should be gone. It is not needed any longer and was removed to make OB properly work in Pharo 1.2. Lukas -- Lukas Renggli www.lukas-renggli.ch
