I see that myfaces includes a BooleanConverter, but when I add this to my
faces-config.xml file ...
<converter>
<converter-id>booleanConverter</converter-id>
<converter-class>javax.faces.convert.BooleanConverter</converter-class>
</converter>
and my selectBooleanCheckbox element is
<h:selectBooleanCheckbox value="#{emailController.fields.addToENews}"
converter="booleanConverter" />
but I'm still getting this error upon visiting my page
(emailController.fields.addToENews returns a string) ...
java.lang.IllegalArgumentException: Expected submitted value of type Boolean
