How to keep error messages during redirect

[kaiwerther]

Hello,

How can i keep error messages during redirect?

Let me explain what i want to do:

I have a button which saves the form data.

When everything works fine i redirect to a new page with a overview over the saved data.
I also want to put an messages (used facesContext.addMessage(componentId, FacesMessage)) that sais that the save was successfully.

Without redirect the message get displayed well but with the redirect the message seems to be lost.

JSF 1.2
RichFaces 3.3.1

Hope somebody knows a solution ...

Best Regards,

Kai Werther

Hello Kai,

Are you using Seam?

[kaiwerther]

No just JSF

(i know, i know i have to learn seam ...)

Looks like, it's not possible out of the box wthout Seam. Redirect creates new request, thus old request-scoped variables are cleared. You can save messages to session, however this doesn't look like a good solution either.

So implementing two phase listeners
- one saving the messages to session
- one restoring the messages from session

is the only way? That can't be ...

It doesn't feel right

Resolved this issue by putting all FacesMessages to Session and restored them by a Phase Listener before RENDER_RESPONSE.
