Attaching methods to VirtualSpace entities

You can attach a Java method to react to any changes in a VirtualSpace entity’s instance value, as well as any changes to its state, by specifying a method name for OnVSChange. To listen to focus changes, use OnVSFocus. The method name specified must be present in the class that is attached to the VirtualSpace. You chose the method name, but your custom method must have the respective Java Method Signatures:

@OnVSChange(name="componentPath")
public void onChange (VSChangeEvent event)

@OnVSFocus(name="componentPath")
public void onFocus (VSFocus event)

The method name editor has a more … button that drops down a menu to help you to create a new method, to select an existing method, or to define or fix the method annotation with the correct componentPath.
