i want to use different adaptor for TextModel, when opening my UI so that when widget is built for it, it will be my own widget, not PluggableTextMorph.. but i found it hard to do.. here what i tried: I try to replace bindings, so at the stage when spec interpreted, it uses my bindings: openWithSpec | old result | old := SpecInterpreter bindings. SpecInterpreter bindings: TxAdapterBindings new. [ result := super openWithSpec ] ensure: [ SpecInterpreter bindings: old ]. ^ result in TxAdapterBindings i initialize it same as morphic bindging, except from text model binding: #TextAdapter => #TxTextAdapter but it is never invoked nor used :( i understand the overall model, but it seems like not completely, (else the above trick would work).. what do i miss? -- Best regards, Igor Stasenko.
