[jsr-314-open] Composite component metadata runtime behavior

Gang - I recently triaged a bug that complained that the "type" attribute of <cc:attribute> was not behaving correctly. The user expected the following attribute specification: <cc:attribute name="foo" type="java.lang.Integer"/> To result in a warning/error when used as follows: <comp:bar foo="MostDefinitelyNotAnInteger"/> This seems like a reasonable expectation. An equivalent test case using, for example, JSP tag files does result in an error. This raises a few questions: 1. Should JSF implementations be making use of composite component metadata (like "type") at runtime to enforce the intentions of the composite component author? 2. Should this behavior be specified? 3. Are there other places where we have similar metadata (eg. Facelets taglib.xml files) that we should review as well? Andy
