How to use facesMessages.add or facesMessages.instance().add

[mean.meanmachine.gmx.at]

Hello,

I read in Seam Reference that it is possible to use facesMessages.add and/or facesMessages.instance().add to add messages to the next rendered page.

Now, I have a page buyCar.xhtml. If the user bought a car and it was written to the database successfully, there is a rule in my buyCar.page.xml where I defined, that the user is redirected to a page successful.xhtml.

This page looks like that:

<!DOCTYPE composition PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
                      "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<ui:composition xmlns="http://www.w3.org/1999/xhtml"
                xmlns:s="http://jboss.com/products/seam/taglib"
                xmlns:ui="http://java.sun.com/jsf/facelets"
                xmlns:f="http://java.sun.com/jsf/core"
                xmlns:h="http://java.sun.com/jsf/html"
                template="layout/template.xhtml">

<ui:define name="body">

    <h1>#{messages['website.headline.successful']}</h1><br />

        <h:messages />
    
</ui:define>
</ui:composition>

Now I thought, that h:messages is replaces by my message added to facesMessages.add oder facesMessages.instance().add, but nothing is shown expected the text between <h1></h1>.

Can you help me and tell me, what I have to do to show this message?

My Bean looks like that:

...
@Stateful
@Scope(CONVERSATION)
@Name("buyCarAction")
public class BuyCarAction implements BuyCar {

                @Logger
                Log log;
...
                
                @PersistenceContext
                private EntityManager em;
                
                @In
                private FacesMessages facesMessages;

...        

            public String buyIt() {
                
                        Bestellung bestellungNeu = bv.createBestellung(bestellung);
                        
                        log.info("BestellungNeu: " + bestellungNeu);
                        
                        final Kunde kundeNeu = bestellungNeu.getKunde();

                        log.info("Kunde Neue Bestellung " + kundeNeu);
                        
                FacesMessages.instance().add("Kauf war erfolgreich");
                                
                return "success";
            }
...

Thanks and best regards,

Dirk

Hi,
try to use the injected facesMessages:

facesMessages.add(Kauf war erfolgreich);

instead of:

FacesMessages.instance().add(Kauf war erfolgreich);

Oh, sorry I did not well understand your post.

Between <h1></h1> you'll always get the message

website.headline.successful

which is defined in your messages_XX.properties file.
When you add a facesMessage, this is not going to replace the message between <h1> tags.
It's going to appear at <h:messages/>

Try to have a look at Seam examples folder.

Hi Nicola,

thanks for your reply! Probably I couldn't explain it correctly. I know, the facesMessage.add-Message is not displayed between the <h1></h1>, but I also have a <h:messages /> in my successful.xhtml.

But it doesn't display my message.

Perhaps you can tell me, if I perhaps have to configure something to get these messages shown?!?! It would be very kind if you could help me.

Thanks and best regards,

Dirk

what version of Seam are you using?

Hello Nicola,

thanks for your Response! My version is Seam 2.1.0 BETA 1 (I get told when startig JBoss or deploying my project).

Hopefully it works with this version, because I don't want to update - I habe a review with my prof next week and if it wouldn't work anymore this would be very bad ;)

BTW: I added <web:redirect-filter url-pattern="/*" /> as read in seam reference to my components.xml

Thanks and a happy new year,

Dirk
