We are using the s:decorate, and in particular with the default edit.xhtml as the template. When we specify the control (in this case a h:selectManyCheckbox) as required, the decoration works correctly. That template uses validateAll internally. It *looks* like validateAll is working correctly. When I remove the required and just depend on the validator annotations to run, they don't. Any pointers on this one? I will look into it further.
