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

             Summary: Validators not invoked for emptyselectManyCheckbox components
                 Key: MYFACES-4050
                 URL: https://issues.apache.org/jira/browse/MYFACES-4050
             Project: MyFaces Core
          Issue Type: Bug
    Affects Versions: 2.2.10
         Environment: Tomcat, WebSphere Liberty
            Reporter: Bill Lucy


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.
