"Illegal state of Component" exception

Under very rarely circumstances the component tree can be changed in such a case that new components are added before a Faces Request starts.
In that case HtmlYComponent may throw an exception.
(HtmlYComponent assumed that in each processDecodes/Updates/Validations a YComponent instance is available)

ERROR [127.0.0.1] (master) [_ErrorPageWriter] An exception occurred
