wicket is not a managed framework. you are in charge of instantiation the
components, thus constructors.

we do, but like i said we let you be in control of instantiation because we
believe that delivers you the most flexibility

yes but this is a gui framework with markup. you cant really compare it to
layout manager gui frameworks. this is also a framework where you have
separation of concerns, designers, etc. so we have a few special
