hi stefan
thanks for the clarification.
what i'd like to achieve right now, though, is the following:
i have a select element which displays all available locales (retrieved via
java.util.Locale.getAvailableLocales) as option elements in alphabetical order.
in the initial state (ie. when creating a new object which should have the
language property) i'd like to show the locale to be (heuristically) considered
the most useful one (aka the default) as the selected one (e.g. "en").
of course, after saving the form data the selected one is displayed.
thus, i need "en" to be selected when there is no property set, yet; and
afterwards i need the chosen locale which is then the property value.
obviously, i need a mixture of both worlds, don't i?
how would i do this?
ciao,
tobi
