File which causes a NPE when exporting xml data from
I created a simple excel document with a mapped xml schema. I then tried to
export the xml data from the excel sheet. This failed with a null pointer
exception.
Here is the stacktrace:
java.lang.NullPointerException

This is the code which calls the poi api:
XSSFMap map = mapInfo.getXSSFMapById(1);
XSSFExportToXml exporter = new XSSFExportToXml(map);
ByteArrayOutputStream os = new ByteArrayOutputStream();
exporter.exportToXML(os, true); // It fails here with a NPE
String xmlData = os.toString("UTF-8");
And I also attached the excel file.
