Iâm trying to customize our current project with multiple baselines meaning BaselineOfCoreProduct and BaselineOfWhiteLabelProduct. The latter is a subclass of the former. My problem is that I donât know which way to choose for loading because Metacello new baseline: #WhiteLabelProduct load that does not work if BaselineOfCoreProduct is in its own package because that is not loaded but the superclass is in there. I saw that I can provide an array to baseline: but regardless in which order I put them the wrong is always loaded first. So order of the array seem not to matter. I could still load BaselineOfCoreProduct first and then BaselineOfWhiteLabelProduct but I would like to have a better way of doing. I could also image putting both baselines in the same package but I donât know how to use Metacello to say it should load a package name and use another named Baseline. Any help appreciated, Norbert
