Title is defined on both side. By default the instance side method points to the class side method. But you can override the instance side method without any problem :) (by example DualChangeSorterApplication redefine title according of the instance) Ben PS: if your title is dependent of the state of your model (by example title ^ self selectedMethod selector you can use self updateTitle to update the title) On Feb 18, 2013, at 10:18 PM, phil@highoctane.be wrote:

Why is the title of the ComposableModel on the class side?

That's annoying if I need multiple windows each having a different title when I do an openWithSpec.
