Android Data Binding: visibility on include tag

Question

As per http://developer.android.com/tools/data-binding/guide.html#imports, we can have such simple expressions in visibility:

Answer 1

This is the direct approach, without having to pass the variable inside the included layout

The above code was all I needed

The interesting thing is if I remove the above ternary operator and simplify it like this,

with addition of an BindingAdapter class with following method,

@BindingAdapter("android:visibility")
    public static void setVisibility(View view, boolean isVisible) {
        view.setVisibility(isVisible ? View.VISIBLE : View.GONE);
    } 

Boom! the OP error invades my entire BuildOutput trace, interesting world of Android
