f:viewAction

Since JSF 2.2, you can invoke an action or actionListener, passing through the JSF phases using f:viewAction.

General Usage

It's possible to choose this method to be executed during non-JSF request (GET) or in a postBack, using postBack attribute. Another useful attribute could be phase, as there you can specify which JSF PhaseId you want that method to be invoked on.
