AddressFormComponent should extend Panel, not FormComponentPanel.
FormComponentPanel is used for special cases where you have several
FormComponents that work together to edit a model value, such as a date
editor that has dropdowns for month and day.
On a FormComponentPanel, you have to implement convertValue() to gather
the input from your subcomponents, synthesize them into a single value,
and call setConvertedValue(). Since you never call setConvertedValue(),
your panel pushes null back into your address model.
