Hi,
I recently encountered this faces-config validation issue as well.
Using e3.5.2, I saw that the issue has been resolved for next Tools 3.2 version.
As I'd like to get that bug away, I went on the development release page to get a 3.2-Snapshot version of that bundle. But unfortunately there are no snapshot releases where that issue'd be resolved, so what can I do so far?
Thx in advance
