io.undertow.request - viewId:/index.xhtml could not be restored.
Any idea why my users are getting the exception below instead of javax.faces.application.ViewExpiredException? My controller uses org.omnifaces.cdi.ViewScoped.
My application is using Java EE 7, JSF 2.2, Primefaces 5.1, Omnifaces 2.0 and Wildfly 8.2.0.
According to the log, it seems the exception happens when user tries to upload a photo.
