Return a HorizontalPanel to a DisclosurePanel when I perform an AsyncCallback

private DisclosurePanel addressDisclosurePanel(String nameId) {
final DisclosurePanel addressDisclosurePanel = new DisclosurePanel("Address");
//Get the Addresses
AsyncCallback<List<Address>> callback = new GetAddressHandler<List<Address>>(PersonalDetailsView.this);
rpc.getAddressList(nameId, callback);

return addressDisclosurePanel;
}

//addressDisclosurePanel.add(addressHorizontalPanel);
into your GetAddressHandler and pass in the newly created addressDisclosurePanel? Alternatively use an anonymous class as callback.

Your order of operations appears incorrect. From your original code I don't see where GetAddressHandler.addressHorizontalPanel is ever actually added to the addressDisclosurePanel.
