MyFaces ExtVal, Richfaces and Mojarra
A lot users asked me for this support.
The current snapshot provides a workaround for this Mojarra issue.
You can use the latest snapshot (which also offers further great features like constraint aspects) or you can patch a released version (see DefaultRenderKitWrapperFactory.java).
Here you can find a patched version of MyFaces ExtVal 1.2.2
Don't forget to add the myfaces-extval-generic-support!!!
