Two things:
1) Are you sure that the element has actually appeared on the page?
Particularly in a real browser (I notice that you're using HtmlUnit)
2) The wait uses generics to make the common case situation you're
running into more efficient:
WebElement data = wait.until(visibilityOfElementLocated(By.id("data")));
The error you're seeing indicates that the element hasn't been
inserted into the DOM, so it's possible that the AJAX call hasn't
returned yet.
