Hi Everyone, Loading Roassal 2 in Pharo 7 with: Gofer it smalltalkhubUser: 'ObjectProfile' project: 'Roassal2'; configurationOf: 'Roassal2'; loadStable. makes the image unusable due to changes in NewValueHolder. Roassal adds: NewValueHolder>>announcer ^ announcer which is fine in Pharo 6 because NewValueHodler is a subclass of Object and initialises announcer in #initialize. In Pharo 7 NewValueHolder is a subclass of Model and relies on lazy initialisation of announcer in the corresponding accessor method inherited from Model. But... since Roassal is overriding the accessor method, announcer is never initialised, with the result that errors similar to: UndefinedObject(Object)>>doesNotUnderstand: #announce: are triggered (often enough that the image is largely unusable). I think the solution is to modify the packaging so that NewValueHolder>>announce is moved in to a separate package that is only loaded in Pharo 6 and earlier. Thoughts? Thanks! Alistair
