Actually, because the BXML ID value is mapped to Component#setName() via the
IDProperty annotation, you could also get the button in the example below via
getNamedComponent("Button1").
However, as Chris noted, getNamedComponent() is not recursive. If you want
access to all values declared with IDs in your BXML file, you should use
BXMLSerializer.getNamespace().get() or implement Bindable in your root element.
