Jukka Zitting commented on JCR-1952:
------------------------------------
The workaround is to look for and remove the Xalan jar from the repository
classpath. The export works fine with the built-in JAXP libraries in all JDKs
we've tested, but it looks like other TransformerFactory implementations (like
the one in the Xalan versions reported here) break the export.
I'm still not sure how to best resolve this. I'm inclined to either revert back
to the 1.4 code (with the potential of introducing other regressions) or going
with a custom XML serializer that doesn't depend on any JAXP libraries (which
would be a notable new block of potentially buggy code).

> When I try to export some nodes with ExportDocumentView I get a DOMException

> 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:
