Vaadin IPC for Liferay version 2.0.0

Does anyone have a good working example for this add-on using Vaadin 7? I’ve tried to use this and I can’t get the communication between components working. Both components are on the same page in liferay and I have a listener that is just supposed to print to system.out but nothing happens when I send a message from the other component.

Thanks!

Nevermind, got it.
