Hi.

I have an app deployed on Wildfly 8.2.1, and this InvalidViewIdException has become almost normal due to its frecuency. I don't know what triggers it, only that this warning followed by this error  show up:

WARNING [org.richfaces.log.Resource] (default task-42) Resource key not foundnull

ERROR [io.undertow.request] (default task-42) UT005023: Exception handling request to /auctions/faces: javax.servlet.ServletException

        at javax.faces.webapp.FacesServlet.service(FacesServlet.java:221) [myfaces-api-2.0.14.jar:2.0.14]

Caused by: org.apache.myfaces.shared.application.InvalidViewIdException

The user logs in, navigate, and it suddenly appears. Of course I don't know what exactly the user is doing right at the time of the error.

Do you have any recommendation on this?

Thanks.
