Unknown formatting object null^null ... again

[Matthias Kräuter <m....@exxcellent.de>]

Hello,

my old problem still exists. The stacktrace now shows line numbers but I
don´t think it helps very much. I tried newer versions of Xalan (2.4D1)
and Xerces (2.1.0) but nothing changed. 

My supplied Document  is not read from file but is a transformation result
I´m holding in memory. I than inserted a document fragment with an
fo:table into it with database data. Could there be a problem with the
namespaces in this  fragment?

The stacktrace:

[reports] [ERROR] Unknown formatting object null^null

UILD FAILED
ava.lang.NullPointerException

My source code looks like that:
                Driver driver = new Driver();
                driver.setRenderer(driver.RENDER_PDF);

               File pdfFile = new File("report.pdf");
               driver.setOutputStream(new FileOutputStream(pdfFile));

               driver.render(pdfDoc);

               driver.run();

pdfDoc is a DOM Document.

My .fo Document with the inserted table:

<?xml version="1.0" encoding="UTF-8" standalone="no"?>
   <fo:root xmlns:fo="http://www.w3.org/1999/XSL/Format">
       ...
       <fo:table>
               <fo:table-column column-width="proportional-column-width(1)"/>
               <fo:table-column column-width="proportional-column-width(1)"/>
               <fo:table-column column-width="proportional-column-width(1)"/>
               <fo:table-column column-width="proportional-column-width(1)"/>
               <fo:table-column column-width="proportional-column-width(1)"/>
               <fo:table-header>
               ...
       </fo:table>
        ...
 </fo:root>

Can anybody give me a hint on that?

Thanks a lot
Matthias

How do you build your Document object? Make sure you are using 
namespace-aware DocumentBuilderFactory, which is not namesapce aware by 
default. Try
dfactory.setNamespaceAware(true);
