not sure what's wrong with your code, but i've done enum selection in
voicetribe with code that looks like the following:
add(new DropDownChoice("genre", new Model()
{
@Override
public Object getObject(Component component)
{
return Genre.valuesSortedByLocalizedName();
}
}, new IChoiceRenderer()
{
public Object getDisplayValue(Object object)
{
return ((Genre)object).getLocalizedName();
}
public String getIdValue(Object object, int index)
{
return object.toString();
}
}));
