I have to set the model of the nested component somewhere. I can't
set it in the constructor, because the model is not available then.
The documentation for FormComponentPanel suggests doing it in
onBeforeRender.

The docs say not to override this method, so I'd rather not do that.
I found that if I initialized the nested component in onBeforeRender
with the model (making sure I do it only once), then I got the
behaviour I wanted. I don't understand why that works though.
