[jira] Commented: (CXF-2340) Unmarshalling Error: UndeclaredPrefix: Cannot resolve 'ns0:Xxx' as a QName: the prefix 'ns0' is not declared

["Daniel Kulp (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/CXF-2340?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12731556#action_12731556 ] 

Daniel Kulp commented on CXF-2340:
----------------------------------


Ok.   This is definitely a bug in JAXB's validation stuff, not CXF.   :-(

When looking up xsi:types, it's not using the NamespaceContext of the original StAX stream.    It's only using the namespace prefixes that it has processed.   Thus, only prefixes defined on the getSedans element would be looked at. 

I'm going to log a bug with JAXB folks.    I'm not really sure what we can do about it.
