in that case i think you should do what martijn said because that is
proper encapsulation. how else can you reuse that combination elsewhere?
IModel model=new Model(new Date());
WebMarkupContainer composite=new WebMarkupContainer("composite", model));
composite.add(new TextFIeld("date", model));
composite.add(new TextField("time", model));
but why not encapsulate it like martijn showed you?

it's not what i wished for.
i wanted my model to contain a Date value, part of each is used by
the date text field and part by the time date field.
i can do something like
form.add(new TextField("date", new Model(getDate(date))));
form.add(new TextField("time", new Model(getTime(date))));
and in onSubmit do something like
toDate(getDateValue(), getTimeValue())
where getDateValue() locates the 'date' text field (how do i do
that?) and returns its model value (the date part) and
getTimeValue() does a similar thing for the time part
but, what i wanted was to create something reusable, that can be
used elsewhere also.
WebMarkupContainer composite=new WebMarkupContainer("id", new
IValueAdapter(){...}); // IValueAdapter can get/set parts of a value
it is
// the equivalent of getDate, getTime, toDate etc.
composite.add(new TextField("date"));
composite.add(new TextField("time"));
(the model is gotten from the form, but of course the composite
component can have its own (in another constructor))
