Very clever. I am impressed. Only problem I can think of is in the
case when I have several bindings. No guarantee that the set method
will be the last one called. I could get around this by including the
calc call in all the set methods, checking in each one that all the
variables are available.
But I expect there must be a standard way of doing it. Isn't that what
the awake method would be for??
In your subcomponent, you could override takeValuesFromRequest() or
appendToResponse(), depending on when you need the results of your
calculation. Don't forget to invoke super's implementation in your
override. You also have the flexibility of doing things before and
after the invocation of super's implementation, depending on your needs.
WO offers many ways to intervene within the request-response loop. It
can be challenging, at least for me, to know the best approach under
various situations, but there's probably always a way to do what you
want when you want to.
