Greetings to all,

In the latest version of RefactoringBrowser from SqueakMap (which is version
22 package) the 'extract method to component' feature fails. Each time when
it tries to display a list of classes the 
'Set(Object)>>doesNotUnderstand: #first' exception is raised.

It seems that MoveMethodRefactoring>>getClassesForTemporaryVariable returns
a collection of the wrong type, which is Set instead of OrderedCollection. 

Thanks for your attention,
Sergey
