Example 7 with CurrentRealm

use of org.eclipse.jface.databinding.conformance.util.CurrentRealm in project eclipse.platform.ui by eclipse-platform.

the class JavaBeanObservableListTest method testSetBeanProperty_CorrectForNullOldAndNewValues.

@Test

    // PropertyChangeEvent to be null, which indicates that an unknown

    // value diff even if the bean implementor is lazy :-P
