Examples with ComponentSystemEventListener javax.faces.event.ComponentSystemEventListener used on opensource projects

Example 1 with ComponentSystemEventListener

use of javax.faces.event.ComponentSystemEventListener in project liferay-faces-bridge-ext by liferay.

the class ResourceRendererLiferayImpl method processEvent.

/**
 * Since the Mojarra {@link com.sun.faces.renderkit.html_basic.ScriptStyleBaseRenderer} class implements {@link
 * ComponentSystemEventListener}, this class must implement that interface too, since this is a wrapper type of

 * to the head (if the target attribute has a value of "head").
