This looks fantastic. Can you think of an elegant way to use similar syntactic
sugar to create LoadableDetachableModels as well?
For example:
// This would return a PropertyModel
model(from(myBean).getChild().getName());
// This a LoadableDetachableModel
loadedModel(from(myService).listUsers());
// Which is more concise than
new LoadableDetachableModel<List<User>> {
protected List<User> load() {
myService.listUsers();
}
}
