plannerEventscomponent is never created, probably because it is never scanned by Seam. You can check it on /debug.seam page. Do you have seam.properties file in your archive?
Thank you Pawel,
There is no error on the page, so I cannot see the debug page
But you are right anyway. I'm using a jboss tools generated ear project. The above code is from the main project, not from ejb project. I have moved the whole package from there to the ejb project and now It's OK.
