// This must be a field:
Editingdomain domain = getEditingDomain();

// public DataBindingContext iniDataBindings() { ...
  IObservableValue observeTextWidget = WidgetProperties.text(SWT.FocusOut).observe(txtTaskName);
  IObservableValue observeSelection = ViewerProperties.singleSelection().observe(tasksTableViewer);

  // [using EMFObservables] Generated by WindowBuilder
  //IObservableValue taskNameValue = EMFObservables.observeDetailValue(Realm.getDefault(), observeSelection, Literals.TASK__NAME);

  // [using EMFEditObservables] Works and shows up in Bindings page of WindowBuilder (but may becaome deprecated API)
  IObservableValue taskNameValue = EMFEditObservables.observeDetailValue(Realm.getDefault(), domain, observeSelection,  Literals.TASK_DEF__NAME);

  // [using EMDEditProperties] Does NOT work and does not show in Bindings page of WindowBuilder
  //IObservableValue tasksNameValue = EMFEditProperties.value(domain, Literals.TASK_DEF__NAME).observe(Realm.getDefault(), observeSelection);

  bindingContext.bindValue(observeTextWidget, taskNameValue, null, null);
