ObservableInt causes crash on DataBinding Library

Question

I was playing with the new data binding library and tried to implement observable interface . But it keeps crashing no matter if i set the age variable to textview or not. The code works fine if i convert age variable to String. Is there any way to make it work with int ?

public class User extends BaseObservable {

@Bindable
public final ObservableField<String> name =
        new ObservableField<>();
@Bindable
public final ObservableInt age = new ObservableInt();}

Crash Log :

Put this in data tag

You need use @{String.valueOf(user.age)} in TextView.

Or @{""+user.age}
