this is fine yes:
TextField<String> tf = new TextField<String>(new
ResourceModel<String>("key"));
the tf.getModel() returns a Model<String> else it cant and getModelObject
also returns a String.
But i agree for a Button if you dont give a model to it it doesn't make
sense
But if you give a model it does make sense.
But for a Textfield it makes sense that you generify it even without a model
because it does inherit the model from its parent..
so yes its a bit of a split what is nice and what you want to do.
