Brian Leathem commented on ARQGRA-302:
--------------------------------------

+1 Registering the class with the Builder#service is a good solution for not having classpath scanning.

> In order to be able hide implementation details of particular page fragments shipped with a framework,
> we should favor injection of Page Fragments by interfaces.
> {code}
> interface Calendar;
> class CalendarImpl;
> @FindBy("calendar") Calendar calendar;
> {code}
> The implementation of the calendar can be registered using services mechanism.
> {code}
> Builder#service(Calendar.class, CalendarImpl.class);
> {code}
> ----
> When there are more {{Calendar}} implementations on the classpath registered, the user have either choice of using particular implementation or, preferably, use self-detection built-in into page fragment implementations -> with the knowledge of a root element, they can detect if they are appropriate implementation for given interface.
> E.g. RichFaces calendar will look a the root element and check whether it has class {{rf-cal}}.
