[errai-dev] Fwd: Errai UI and DataBinding

I'm voting for adjectives I guess. It's typically the way that CDI
Qualifiers look when functioning with @Inject. Granted, these aren't
qualifiers, but they might as well be by how they behave and actually
modify the result of the injection.

I'm 100% sure how I feel about @AutoBound - but I'm not 100% sure about
@Bound.


As adjectives:

@Templated
public class Thing extends Composite {

  @Inject
  @Bound
  private TextBox input;

  @Inject
  @AutoBound
  private DataBinder<Model> binder;

}


As verbs:

@Templated
public class Thing extends Composite {

  @Inject
  @Bind
  private TextBox input;

  @Inject
  @AutoBind
  private DataBinder<Model> binder;


}
