Well the code is a bit more complex that what I originally pasted.
ComponentA is instantiated in an overridable method so that subclasses can
provide a different implementation. Furthermore, the model cannot be
decided at initialization time, so you can't simply call
componentA.setModel() right after it is constructed. So I thought about
using a behavior which can be added after the component is constructed and
which can change the model whenever needed.
Nonetheless, based on your feedback, I think I have found a way to
refactor it such that the model is provided at initialization time.
But I guess the question still stands - can Behavior#onConfigure change a
component's model or is this not a valid operation?
