It is common, in a detail screen, to handle the user input. In our case, our Person Object holds the oid of the country where it's located and we're only interested in this oid and n ot the whole country information (ie. the country oid is a foreign key in our Person Object). The LovBox will do that for us, first using a LOV to display the selected field instead of just the country's oid (the only information contained in Person) and returns the country oid when a selection is made so that we can modify the Person Object accordingly without further manipulation.

As a matter of fact a LOV can be used wherever you choose to use it, a non editable LovField (a JTextField matching an oid and displaying a selected field) or a LovButtonGroup (for the gender for example) would be valid uses of the LOV...
