#call: replaces the current component with another, and should not
be used in render methods: only in callbacks.

If you want your top-level component to have no native rendering of its own,
just calling other components, you should be using a WATask and overriding #go
instead of overriding #renderContentOn: in a WAComponent.

See

and

for details. (And yes, I'm moving some of this into the FAQ when I get back
from this trip!)
