Hi Ricky, Thanks for your answer. But my problem is that my collection is not sorted after this kind of message: aCollection sorted: [:e1 :e2 | e1 staticNeededPackages size < e2 staticNeededPackages size] I don't really understand why!

For more examples, just search for the senders of the selector #sorted: Cheers, Ricky On Apr 16, 2008, at 11:55 AM, Romain PEIRS wrote: _______________________________________________ Moose-dev mailing list Moose-dev(a)iam.unibe.ch https://www.iam.unibe.ch/mailman/listinfo/moose-dev
