well, i find that people often forget how easy it is to subclass components
and create
new ones in wicket. if your own way of doing date picking is something you
do more
than twice on your site, a simple panel could collapse all the related
components and
initialization into one little class like DatePickerPanel so a usage of it
looks more like
the code below and the details of how it works don't bleed out into your
usage code.
it does take a little bit of fussing to do that, but the code is easier to
work with and
much more encapsulated.
private void addReservationDates()
{
// create the feedback panel
FeedbackPanel feedback = new FeedbackPanel("feedback");
feedback.setOutputMarkupId(true);
add(feedback);
add(new DatePickerPanel("checkIn", new PropertyModel(roomRequest,
"checkIn")));
add(new DatePickerPanel("checkOut", new PropertyModel(roomRequest,
"checkOut")));
...
}
