exception...non-threadsafe access(I think is bug)

I am getting exceptions from xwiki if I open up two windows in firefox which I assume are trying to use the same session. I think I should be able to do this, but xwiki is balking..... 09:34:32,349 WARN http-80-Processor25 RequestUtils:createActionForm:177 - No FormBeanConfig found under 'view' 09:34:32,456 WARN

[mailto:DHiller@carrieraccess.com] Sent: Thursday, December 29, 2005 8:46 AM To: &#39;xwiki-users(a)objectweb.org&#39; Subject: [xwiki-users] mail plugin I saw the default installation refers to some MailPlugin..... com.xpn.xwiki.plugin.mail.MailPlugin A google on this only revealed a bunch of checkins. How do I use this Mail Plugin? I am assuming it is to register for notifications on pages? I saw another plugin that I would have to install(and frankly, I tried but the instructions refer to stuff that isn't there or I can't find in xwiki like Xwiki.Toolbar page). Any info on mail plugins would be appreciated. thanks, dean
