Hi!,
The lifecycle extension was just an easy entry point to register the
listener, if you're doing it elsewhere it should be fine, you should be
receiving the events as soon as you've registered it.
Regarding the registration,
WikiEventManager.addWikiEventListener(org.apache.wiki.WikiEngine.class, new
WikiEventListener() {
Having skimmed the code this morning, I think it should use the engine
instance, something like
WikiEventManager.addWikiEventListener(m_engine, new
WikiEventListener() {
As this is where WikiJSPFilter send the events. Would you mind trying to
debug inside WikiEventManager.fireEvent to see where the events are being
dispatched? I'll try to look into this throughout the week, but can't
promise anything.
Best regards,
juan pablo
