Since 2.0.8/2.1.2 this is disabled on Production environments unless it enabled on web.xml file.

Security License Summary Below is the list of available web context parameters supported: Web Context Parameters Artifact Id: myfaces-api Name Default Value https://cwiki.apache.org/confluence/display/MYFACES/Handling+Server+Errors Expected Values Since Description Source Class javax.faces.STATE_SAVING_METHOD server server,client 1.1 Define the state method to be used. There are two different options defined by the specification: "client" and "server" state. When "client" state is configured, all state information required to create the tree is embedded within the https://myfaces.apache.org/core12/myfaces-impl/webconfig.html data rendered to the client. Note that because data received from a remote client must always be treated as "tainted", care must be taken when using such data. Some StateManager implementations may use encryption to ensure that clients cannot modify the data, and that the data received on postback is therefore trustworthy. When "server" state is configured, the data is saved somewhere "on the back end", and (at most) a token is embedded in the data rendered to the user. javax.faces.application.StateManager javax.faces.DEFAULT_SUFFIX .jsp 1.1 Indicate the default suffix to derive the file URI if extension mapping is used. javax.faces.application.ViewHandler javax.faces.CONFIG_FILES 1.1 Comma separated list of URIs of (additional) faces config files.
