Hi,
1. Let's move this thread to eclipse.platform because this is where
databinding is discussed
2. My impression was always that this is exactly the task of the Realm
(syncing from back from a NONE-UI thread but I could be wrong here).

Correct. Here's what you want to do:
final IObservableValue observable = ... // your observable
final Object newValue = ... // the new value you want to set
observable.getRealm().exec(new Runnable() {
public void run() {
observable.setValue(newValue);
}
});
