Can you addMessage() from an Action method?

[SO...@austin.rr.com]

>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.

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