How to synchronize scroll bars on JavaFX?

There are two textareas in my application. I want to synchronize the scrollbars when I move one of them But I can't find a way in JavaFX 2.2

Solution

This works for me:

TextArea ta1 = new TextArea(),ta2 = new TextArea();
ta1.scrollTopproperty().bindBidirectional(ta2.scrollTopproperty());

Generally, you can apply lookupall (string) operation in textarea to find scroll bars in textarea and bind their values in both directions
