When a composite component is used inside a datatable, the resolving of the general "cc"-attribute does not work consistently. For value bindings (with e.g. inputText) everything seems to be fine, but when used inside an "actionListener"-attribute or an "action"-attribute (with e.g. commandButton) the resolvement of "cc" fails. I've isolated the problem to the method "CompositeComponentELUtils.getCompositeComponentBasedOnLocation(..)" which checks if the parent component in the component stack is a "composite component". The "HtmlDataTable" element is not recognized as such.
