JSF 1.1 required a label for SelectItem (unless you created it using a trick).
JSF 1.2 does not require a label.
It was a deficiency in the JSF 1.1 spec, but it's not inconsistent.
Both work as advertised.

Thanks Mike, that seemed to fix it. I was not using a label with
s:selectItems under a f:selectOneMenu using JSF 1.2 RI with no error. I
guess MyFaces may be part of the inconsistency.
Thanks again!
