Sure will I’m actually writing up the docs on the Seam 3 docs right now. Also — those silly exceptions should be resolved in Alpha 3, as well. Thanks again for your help!

Thanks Lincoln, this looks great! – it should tide me over until the Seam 3 Faces module is ready.

This will work with JSF2 won’t it?

You could add a check to see if the message already exists. Only add the message if it is not already present in the list.

for (Iterator iter = facesContext.getMessages(null); iter.hasNext();) {
messages.add(iter.next());
iter.remove();
}

iter.remove(); doesn’t work on MyFaces, it’s probably because MyFaces return copy of collection so you remove item from copy not from orginal collection.

First message is saved in INVOKE_APPLICATION, second in RENDER_RESPONSE and also there is orginal message in facesContext so I get 3 same messages on page after all.

Hi,

Very nice, helped a lot…
I tried to implement a CDI version of your idea, see my questions on the weld forum :

Thank you.

Hmmm… Can you check to see if the method is being called twice? If so… why? What phases? It may depend on your implementation of JSF… You’re probably using MyFaces?

Works great! One question: I get duplicated FacesMessages when returning a String value of null from a JSF action method, to indicate the previous page should be rerendered. Returning a specific String works fine. Is there a way to work around this, or is it generally bad practice to return null from such methods?
