Andreas Raab uploaded a new version of Monticello to project The Trunk:
http://source.squeak.org/trunk/Monticello-ar.364.mcz
==================== Summary ====================
Name: Monticello-ar.364
Author: ar
Time: 13 February 2010, 3:33:06.896 pm
UUID: 874084f3-a9ec-034c-b6d7-e31cb3f74234
Ancestors: Monticello-nice.363
Some fixes for Monticello:
- Deal with nil subclasses properly
- Handle DuplicateVariableError to allow moving variables between subclasses and superclasses when reshaping classes
- Load errorDefinitions right away since any delayed class definitions should be present before methods can be loaded.
