Hi, For backwards compatibility, when restoring the view we need to know if older (<1.2) ViewHandler and StateManager are used in order to fall into 1.1 behaviour if they are older. The RI checks the faces-config file of the artifact [1], inferring the version from the XML grammar (name of the DTD or schema). If it is not the 1.2 schema, the behaviour is the 1.1 one. Do you have a better idea on how to check the version used in the implementation of an artifact (e.g. tomahawk)?
The resulting error of not tracking the version can be observed when running the sandbox with myfaces 1.2, in the convertNumber example. cd tomahawk/sandbox/examples mvn -PjettyConfig clean jetty:run -Djsf=12 With the RI (-Djsf=ri12) this does not happen.
