-----------------------------------------

In theory the patch is valid, but I have not tested it yet.

> Custom validators are not invoked for selectManyCheckbox component, if the component
has no selections made; this can be an issue if we want to handle the null/empty case in a
validator.  The following context params address this case:
> 	<context-param>
> 		<param-name>javax.faces.INTERPRET_EMPTY_STRING_SUBMITTED_VALUES_AS_NULL</param-name>
> 		<param-value>true</param-value>
> 	</context-param>
> 	
> 	<context-param>
> 	    <param-name>javax.faces.VALIDATE_EMPTY_FIELDS</param-name>
> 	    <param-value>true</param-value>
> 	</context-param>
> But these params do not affect the behavior here.  Based on my understanding of the spec,
it seems that this behavior should be changed.
