----------------------------------
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.
