Ken,
Thanks for your reply.

I don't think so either. I took out one filter that I thought could
cause the trouble, and the result was still the same.

I don't use Ajax4JSF, but I do use Spring Framework to configure beans.
I suspect there may be some configuration problem with Spring Framework
when using Woodstock's AJAX.
I didn't understand the above component section, are you saying that I
should (or should not) have it included in the configuration file. I
don't have it in my configuration file, I thought it would be included
in some configuration file of Woodstock's jar file.

I wonder if it has something to do with the bean being serialized by
Spring framework?
After posting the mail, I set the "submitForm" to "true" and the event
listener gets called and things work as it should be. Of course, then
it is not AJAX.
Thanks,
