public class CometdPushBehavior
extends org.apache.wicket.ajax.AbstractDefaultAjaxBehavior

This behavior will be asked by client side when it will receive a cometd event associated with the kind of event There is currently no support for multiple cometd servlets. It is not possible to override which URL to use via the getCometdServletPath() overridable method. But two cometd instances cannot be used simultaneously.
