To be informed of events, a listener has to be registered with the respective event source. <P> The portlet container delivers all events to the respective event listeners (and thereby the portlets) before the content generation is started. Should a listener, while processing the event, find that another event needs to be generated, that event will be queued by the portlet container and delivered at a point of time that is at the discretion of the portlet container. It is only guarantued that it will be deliverd and that it will happen before the content generation phase. <P> This also means, that no further events will be delivered once the content generation phase has started. For example, message cannot be sent from within the service() methods. The resulting message event will not be delivered and essentially discarded. <P> Intelligent portlet containers should provide a cyclic event detection mechanism, so that the portlet container does not come to a screaming halt, if two or more portlets happen to send each other events that are triggered by each other.<P><P><DL><DT><B>Since:</B></DT> <DD>4.1 * @deprecated since 6.0.
