Subject [jira] Commented: (MYFACES-1733) [Seam] Server-side state saving not working correctly
Date Tue, 09 Oct 2007 14:08:50 GMT

    [ https://issues.apache.org/jira/browse/MYFACES-1733?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#action_12533372
] 

Michael Kurz commented on MYFACES-1733:
---------------------------------------

The problem seems to be that Seam uses a GET-Parameter for navigation. But those parameters
are only read by Seam if renderResponse is called in the restore-view-phase. This only happens
if no previous state is available (with client state saving) or if there are no POST- or GET-Parameters
at all (should happen for server state saving).

I provided a patch for 1.1.6 where renderResponse is called if there is no special view state
parameter. This should fix the server state saving problem with seam.

> Sometimes when using server-side state-saving some state is fixed and won't ever update.
> I don't know how exactly this is caused, but it occurs a lot when using JBoss Seam.
> It is consensus in the Seam community not to ever use myfaces with server-side state
saving or even better not to use myfaces, but the RI instead.
> Here is how to reproduce reliably with one of the Seam example applications:
> - download and unzip tomcat 5.5.
> - download and unzip JBoss Seam 1.2.1.
> - edit <seam-install-folder>/build.properties and specify the path to tomcat
> - edit <seam-install-folder>/examples/seampay/resources/WEB-INF/web.xml and change
state saving method to server.
> - run ant deploy.tomcat from <seam-install-folder>/examples/seampay/
> - open http://localhost:8080/jboss-seam-pay
> - try to click on different accounts.
> => Only the first selection ever will make it. All others are ignored. Change back
to client side state saving and everything works ok. 
> I tried to look into this, but I am way over my head here with the internals of JSF and
MyFaces.
