I am trying, and failing, to create a command that acts upon a model. When a command calls asComponent it usually gives itself as a model. If I do: asComponent ^ (model description asComponentOn: model) addValidatedForm: (Array with: #save -> 'Confirm' with: #cancel); yourself Instead then everything works fine until the container component answers the model, and the answer handler is expecting aCommand not an instance of some other class Any ideas would be appreciated.
