-------------------------------------
We encounter a similar issue when using JR 1.5 with JBoss - namespaces are
declared twice in the first node.

> When I try to export some nodes with ExportDocumentView I get a DOMException
> with Jackrabbit 1.5.2. Version 1.4.6 works fine. Xerces version was 2.8.1.
> Code:
> Document document = documentBuilder.newDocument();
> Element exportElement = (Element)
> document.appendChild(document.createElement("Export"));
> Result result = new DOMResult(exportElement);
> TransformerHandler transformerHandler =
> saxTransformerFactory.newTransformerHandler();
> transformerHandler.setResult(result);
> session.exportDocumentView(workflowNode.getPath(), transformerHandler, true,
> false);
> Exception:
> org.w3c.dom.DOMException: NAMESPACE_ERR: An attempt is made to create or
> change an object in a way which is incorrect with regard to namespaces.
