Just got home and tried autoAccept and got a "MessageNotUnderstood:
TextModel>>autoAccept:" error.
Though after changing `initializeWidgets` to the following, it worked as

<code>
self instantiateModels: #(
textName TextInputFieldModel
labelGreeting LabelModel
buttonGreet ButtonModel
).
</code>
Is what I have done the right way to do it?
