public interface PageEvent<T extends PageActionContext> extends BaseChannelEvent
PageEvent which will be put on the internal Guava event bus for
synchronous events dispatching where listeners to this event can inject logic or short-circuit
processing by setting a RuntimeException
through PageEvent#setException(java.lang.RuntimeException). When a RuntimeException is
set on this PageEvent by a listener, the
org.hippoecm.hst.pagecomposer.jaxrs.services.AbstractConfigResource#publishSynchronousEvent will rethrow the
exception. The reason that this has to be done via this PageCopyEvent object is that Guava
com.google.common.eventbus.EventBus always catches an exception thrown by a listener, even when injecting a
custom com.google.common.eventbus.SubscriberExceptionHandler
Note that listeners for PageEvents must never invoke
HstRequestContext#getSession()#save(). Changes in the JCR Session
will always be persisted by the code that posted the PageEvent to the guava event bus
