that is not my problem.
my problem is that i have two components (text fields) - one for date,
one for time, whose combined value is my model value.
i can, of course, create a custom model, and onSubmit get its values,
combine them, and put in the form's model. but this is awkward, and
not component oriented.
i want to create a component that means "the values of the children of
this component will be combined to its value"
