DataBinding with <include> tags

DataBindingAdapters.java

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

layout.xml

Problems.md

First problem

Auto completion for ConstraintLayout's contraints would not work (nothing shows up) while writing them inside the <include> tag.

Second problem

Data Binding's code generation would not use properly the binding adapter. i.e. instead of will fail calling path.util.DataBindingAdapters.setVisibility(this.user, viewModelIsContentful);, the generated code is this.user.setVisible(viewModelIsContentful); which does not exist as this.user is an instance of UserBinding and I did not set any variable named visible.
