It's working but is far from satisfying... It breaks the encapsulation of
the sub-classes (and those of the sub-sub-classes) because they have to know
they can't use add() anymore but have to use some addToForm(). Once you have
a form somewhere in the hierarchy, trouble begins.

Also, you cannot declare the form as a transparent resolver anymore which
means that every component, not only form components, need to use that
special method. I'm currently trying to find a way to avoid changing all the
hundreds of add() calls in my project...

I have found that you only need to add items directly in the child class to
the form.

We have other panels and components that can be added to each other as you
would normally its just the elements directly inside the sub-class that need
to be added to the form.

Not sure if that helps, or even make sense.
