[JBoss Seam] - Re: Locale selector can not change the locale on Seam 2.0.0.
by jazir1979
Hi Joshua,
Sorry this isn't much help, but I can say for certain that I did not experience this when I upgraded our project to 2.0.0.GA. Also, I don't remember having to change any code to get it to work.
I'm changing it with a command button that has the localeSelector.select action.
good luck,
Daniel.

| I faced a problem on locale selector as defined in documentation. Everytime I hit the submit button, it doesn't change the locale as written in the documentantion. OTOH, it goes back to the default locale. If I wanted to be able to change the locale, I must set it up from my browser first. I didn't encounter this problem during the Seam 1.2.0.GA usage. Did anyone encounter the same problem as I did? I also could not find a samples on this too to reproduce the problem.

[Tomcat, HTTPD, Servlets & JSP] - Re: Session is getting merge with other session
by bstansberry＠jboss.com
If at the end of your application workflow, there is a natural place to do session.invalidate(), then sure, I encourage you to do that. That will save you memory.
Session ids are generated from a VM singleton, using a random generator seeded by a timestamp and the VM's free memory (which are unlikely to be duplicated across VMs in a cluster). The class follows, in case you are interested. I've never heard a case of this algorithm generating noticeable duplicate ids. I have seen reports on this forum of non-clustered webapps getting duplicate ids when more than one JBoss instance is on the same machine. But clustered session ids use a different algorithm.
Have you heard of more than 1 case of this? If you have, that would in my mind pretty much rule out a chance session id collision.
Anyway, invalidating the session if you know its done would reduce the already extremely low chance of a problem from session id collision.
Here's the SessionIDGenerator class:
