You can do this with success. This web site is pretty old.

From all examples, it appears that you should be able to call addMessage() from within an action method, but when I try this, the message is not displayed. Contrarily, I found this discussion where it says that it isn't possible: http://jsf-faq.com/faqs/messages.html and that you have to use a validator. I tried using a validator and it did work (the message gets displayed); however, I think that this approach is rather limiting. There are errors that are dependent on more than one input. I am out of ideas. Can you call addMessage() from within an action method and have the error messages (via <h:message for="" />) show up? Thanks.
