I have a configuration as follows : spec for: #common do: [ "a class in package BBB inherits from a class in package AAA" spec package: 'AAA'; package: 'BBB' with: [spec requires: 'AAA'] ]. Now, when I try to load this configuration, it fails to properly load the package BBB (there are some missing classes) with this msg: *This package depends on the following classes:* * A class in package AAA* *You must resolve these dependencies before you will be able to load these definitions: A class in package BBB.* It seems that there is a way to load packages in a linear order ( http://code.google.com/p/metacello/wiki/FAQ#Controlling_Package_Initializati...). However, my project defaults is already set to linear and after reading this post my problem is not resolved. Can anyone help me how I can enforce package AAA to load before BBB? tx, usman
