### Question:
ImageViewBindingAdapter implements GriffonPivotAdapter, org.apache.pivot.wtk.ImageViewBindingListener { public void imageBindMappingChanged(org.apache.pivot.wtk.ImageView arg0, org.apache.pivot.wtk.ImageView.ImageBindMapping arg1) { if (imageBindMappingChanged != null) { imageBindMappingChanged.call(arg0, arg1); } }  CallableWithArgs<Void> getImageKeyChanged(); CallableWithArgs<Void> getImageBindTypeChanged(); CallableWithArgs<Void> getImageBindMappingChanged(); void setImageKeyChanged(CallableWithArgs<Void> imageKeyChanged); void setImageBindTypeChanged(CallableWithArgs<Void> imageBindTypeChanged); void setImageBindMappingChanged(CallableWithArgs<Void> imageBindMappingChanged); void imageKeyChanged(org.apache.pivot.wtk.ImageView arg0, java.lang.String arg1); void imageBindTypeChanged(org.apache.pivot.wtk.ImageView arg0, org.apache.pivot.wtk.BindType arg1); void imageBindMappingChanged(org.apache.pivot.wtk.ImageView arg0, org.apache.pivot.wtk.ImageView.ImageBindMapping arg1);  }### Answer:
@Test public void testImageBindMappingChanged() { final boolean[] invoked = new boolean[1]; CallableWithArgs<Void> callable = new CallableWithArgs<Void>() { public Void call(Object... args) { invoked[0] = true; return null; } }; assertNull(adapter.getImageBindMappingChanged()); adapter.imageBindMappingChanged(null, null); assertFalse(invoked[0]); adapter.setImageBindMappingChanged(callable); adapter.imageBindMappingChanged(null, null); assertTrue(invoked[0]); }
