Example 20 with CurrentRealm

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

the class JavaBeanObservableSetTest method testSetBeanProperty_CorrectForNullOldAndNewValues.

@Test

    // The java bean spec allows the old and new values in a
    // PropertyChangeEvent to be null, which indicates that an unknown
    // change occured.
