@paltherr Good  catch. This needs a JBS bug ID. Maybe @hjohn would help sponsor this for you (in which case he could create the doc bug)?

See the [CONTRIBUTING guidelines](https://github.com/openjdk/jfx/blob/master/CONTRIBUTING.md) for information about how to file a bug (along with other information about pull requests). As this is a simple doc bug, you won't need a very detailed description in the bug report.

The existing example code doesn't compile, since there is no `ObservableValue::setValue` method.

> I noticed that here and here in the same file you have the same issue and avoid it by using a var, which looks cleaner. My fix should probably do the same.

Either is fine with me. I'll let @hjohn decide, since he wrote all three examples.
