org.jboss.weld.context.NonexistentConversationException can't be catched by a rule in web.xml

Let's say that page http://localhost:8080/test6/faces/index.xhtml?cid=1 can be rendered. If conversation time out and user tries to access page again, error page occures with following message: XML Parsing Error: no element found Location: http://localhost:8080/test6/faces/index.xhtml?cid=3 Line Number 1, Column 1: even if rule for exception exists in web.xml <error-page> <exception-type>org.jboss.weld.context.NonexistentConversationException</exception-type> <location>/faces/error.xhtml</location> </error-page> Same error occures if user change url manualy by changing cid number to non existing.
