RichFaces is undefined, a4j is undefined, ModalPanel is undefined JS error -------------------------------------------------------------------------- Key: RF-13124 URL: https://issues.jboss.org/browse/RF-13124 Project: RichFaces Issue Type: Bug Security Level: Public(Everyone can see) Components: base functionality Affects Versions: 3.3.3.Final Environment: Sun Solaris Operating System Java 1.6 Weblogic 10.3.5 cluster, Load Balance by Apache server with Weblogic loadbalancer pluginiexpl Reporter: Azad Akbar Labels: richfaces Fix For: 3.Future We often get these errors after a restart or redeploy of application on Weblogic 10.3.5 server The error is, a4j is undefined, ModalPanel is undefined, RichFaces is undefined JS errors. The Weblogic is a cluster with two Managed Servers. The error comes from only on of the Managed Server, whereas the other one is working fine. Load Balancer is Apache server with plugin for load balancing Weblogic servers. This issue happens especially after a restart of the Weblogic servers or Redeploy of applications on the Weblogic servers. The solution is strangely "Do a restart with purge cache, followed by redeploy of the application" Could this be because the path to the file that contains these javascript objects/variables is generated by some filter in RichFaces and attached to the header of the rendered xhtml page but the RichFaces code fails to put the file on the server path. Or maybe the browser mistakenly starts sending the request to the other server with this path information that was sent from the server 1 of the cluster. Or would it be because the application is not getting properly deployed on the Weblogic servers, since the issue goes away after redeployment. The version of RichFaces is 3.3.3 Final Please note that we have enabled sticky session on the Apache LoadBalancer.
