I’m thinking that all changes should go through a model and not the data source. The model can interface with that. So: model.getItemAt() and model.addItem() and so forth.
This way the data source can be anything. Then our models like ArrayListSelectionModel can dispatch those events. We can even have ArraySelectionModel. App writers can extend these classes to make custom models or implement the interfaces from scratch. It would certainly help to have some uniformity.
