[jira] Resolved: (XERCESJ-1043) LSSerializer fails when validating external entities with namespaces
[ http://issues.apache.org/jira/browse/XERCESJ-1043?page=history ]
Michael Glavassevich resolved XERCESJ-1043:
-------------------------------------------
Resolution: Fixed
NamespaceSupport is working as designed. This class expects that the prefix and namespace will be identical references for equal strings. The problem was that the serializer was not passing in unique string for the prefix. We now retrieve such a string from the SymbolTable. Should be fixed now in CVS. Thanks for reporting.

> LSSerializer writer = impl.createLSSerializer();
> writer.write(document, output);
> I recieve this error:
