[errai-users] NotSerializableException: HttpSessionProvider$SessionsContainer

Hi, I'm using the following configuration: sessionManager = org.apache.shiro.web.session.mgt.DefaultWebSessionManager securityManager.sessionManager = $sessionManager sessionDAO = org.apache.shiro.session.mgt.eis.EnterpriseCacheSessionDAO securityManager.sessionManager.sessionDAO = $sessionDAO cacheManager = org.apache.shiro.cache.ehcache.EhCacheManager securityManager.cacheManager = $cacheManager and receiving the following error after logon: java.io.NotSerializableException: org.jboss.errai.bus.server.HttpSessionProvider$SessionsContainer Is there sometime I'm missing or should the static inner class SessionsContainer implement Serializable? Thank you in advance! Best regards, Wim
