I have a `StringProperty` and I want to use it for...

I have a StringProperty and I want to use it for a DatePicker which required an ObjectProperty<LocalDate>
Is there a way to pass a converter or something to do the mapping between the properties? What's the best practice for this?

I can't change the type of the StringProperty variable, it's a bit of a special case.

I had to do something like this often enough that I wrote an extension function fun <T> StringProperty.toObjectProperty( to:(String)->T, from:(T)->String ): ObjectProperty<T>.

[sbyrne]

It just created a SimpleObjectProperty<T> and set up listeners to copy values back and forth, with conversion.

@sbyrne I see, I was expecting something like this in the std lib but I guess there isn'tو for some reason. Thank you!
