>
> 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.
