[Pharo-project] updating the state of a state button

In a dialog, I found the state of a button is not updated, even after self changed. See the code bellowm with methodes defnied in the dialog: newMySketchesButton ^ self newButtonFor: self getState: #isMySketches action: #sketches arguments: nil getEnabled: #beMySketches "alway return true" label: 'MySketches' translated help: 'View my sketches' translated sketches self isExamples: false. isExamples: boolean isExamples := boolean. self changed isMySketches ^self isExamples not There is no #update at the dialog level, how should the button state updated? (I know I can do it by-hand) Implementing myself an #update or do I miss something? Thanks Hilaire -- Education 0.2 -- http://blog.ofset.org/hilaire
