Provides inter portlet communication for portlets deployed to a Liferay server
REPLACED BY Vaadin IPC for Liferay
The standard inter portlet communication (IPC) mechanism defined in the portlet 2.0 specifications requires the page to be reloaded when the communication takes page. This is not very nice, especially for Vaadin application.
The add-on also allows Vaadin portlets to communicate with non-Vaadin portlets and Liferay gadgets, using the same API.
The data sent using this mechanism is limited to a String and is passed to the target portlet(s) on the client side. If you want to pass data on server side you can store the data somewhere where it is available to the target portlet and only pass a reference which allows the target portlet to lookup the real data.
