>                 URL: http://issues.apache.org/jira/browse/COCOON-1876
>             Project: Cocoon
>          Issue Type: Bug
>          Components: Blocks: XML-DB
>    Affects Versions: 2.1.9
>            Reporter: Don Grodecki
>         Assigned To: Antonio Gallardo
>             Fix For: 2.2-dev (Current SVN), 2.1.10-dev (current SVN)

> The XMLDBTransformer blows up Saxon, which does not like null URIs. The
> following fix seems to work, replacing null in the first parameter to
> addAttribute with "".
>                 // Report result
>                 AttributesImpl attrs = new AttributesImpl();
>                 attrs.addAttribute("", XMLDB_QUERY_OID_ATTRIBUTE,
>                         XMLDB_QUERY_OID_ATTRIBUTE, "CDATA", this.key);
>                 attrs.addAttribute("", XMLDB_QUERY_TYPE_ATTRIBUTE,
>                         XMLDB_QUERY_TYPE_ATTRIBUTE, "CDATA", this.operation);
>                 attrs.addAttribute("", XMLDB_QUERY_RESULT_ATTRIBUTE,
>                         XMLDB_QUERY_RESULT_ATTRIBUTE, "CDATA", result);
> The API being called is the SAX org.xml.sax.ContentHandler.createElement().
> From the Interface definition at http://www.saxproject.org/apidoc/index.html:
> "Parameters:
> uri - the Namespace URI, or the empty string if the element has no Namespace 
> URI or if Namespace processing is not being performed
> ..."
> Note that a null value is not specified as one of the options:
> Both the versions that I have, which are saxon8 (jar contents dated
> 4/7/2005) and saxonB-8.7.3 (the latest), blow out with a
> NullPointerException.
> I have used Saxon quite a bit, for XSLT 2.0, and the only calls to Saxon
> with null URIs have been from the XMLDBTransformer.
