Easiest way I can think of- cut out the first half of the table 
content.  See if rendering breaks.  If it doesn't, then the 
problem is in the second half of the table content, so focus on that.  Keep 
paring out half of your table content until you've either found the content 
that's causing your headaches or until the bug vanishes and you get more 
headaches  ;)

This is really ugly. Look up javax.xml.transform.dom.DOMSource.

Omit the driver, and use
  transformer.transform( strSource, new StreamResult(new File("file.fo")));

  Run 
  your XML file and XSL file through the XT program found here: http://www.blnz.com/xt/index.html
   
  This 
  should give you an XSLT result.  The resulting information should be a 
  purely FO document so that any of us could immediately run it in FOP and see 
  what's what.

Hello,
 
i 
don't know how to view my xslt result.
i 
am working on a project , where all the data of the software can be saved to 
xml...
now i want to create a pdf report file out of the xml data, and i 
only provide and xsl file with FO tags.
so 
i have written a java class with the following code:
 
{
// create XML Tree with project data
  Document doc = 
DocumentFactory.getInstance().createDocument();  YpiXML ypiXML 
= new YpiXML(projekt);
 
  ypiXML.setFile(outFile);  
ypiXML.saveProjektDaten(doc, true);
 
 OutputStream xmlstream = new 
ByteArrayOutputStream(); ByteArrayInputStream istream = 
null; String s = ""; OutputFormat outFormat = new 
OutputFormat(); outFormat.setEncoding("windows-1252"); XMLWriter 
writer = new 
XMLWriter(xmlstream,outFormat); writer.write(doc); writer.flush(); s 
= xmlstream.toString(); stream = new 
ByteArrayInputStream(s.getBytes());String stemp = 
istream.toString(); istream.close();Source strSource = new 
StreamSource(new StringReader(s));TransformerFactory transformerFactory 
= TransformerFactory.newInstance ();  Templates template = 
transformerFactory.newTemplates(new StreamSource(xslFile));Transformer 
transformer = template.newTransformer();Driver driver = new 
Driver();driver.setRenderer(driver.RENDER_PDF);FileOutputStream fo = 
new FileOutputStream(outFile);driver.setOutputStream(fo);Result 
saxResult = new SAXResult( driver.getContentHandler() 
);transformer.transform( strSource, saxResult );
driver.reset();fo.flush();fo.close();}

  This works very 
  well, i only have to provide an xsl File that contains the information, 
  which data of the xml file should be shown in the 
  pdf.
  when a table 
  larger than one pdf (A4) page has to be created, the endless loop appears. 
  otherwise it runs with no problem...
   
  As i am really new 
  to FOP, any hints are welcome,
   
  regards, 
  
   
  T. 
  Kuhn

  I can't reproduce the problem. 
  Posting snippets form the XSLT is unwise, you should 
  post the result of the XSL transformation, after 
  trimming it to the part which actually 
  demonstrates the problem, and perhaps anonymizing 
  company data. 
  I guess you'll spot the problem yourself when 
  looking at the XSLT result.

hi,
 
simply 
terminating the endless loop would be a good "first fix" of the problem for me 
too...
 
This 
is the part of the code creating the tables which will not fit in one page in 
some cases...

  I'm 
  actually trying to shore up this from happening, but it won't address your 
  situation, since my patch simply terminates the endless loop rather than 
  necessarily finding and making splits more aggressively.
   
  Could you post a copy of the FO data that is triggering the endless 
  loop?  I'd like the opportunity to analyze it.  Putting in a bug in 
  Bugzilla and attaching some sample data there would be even 
  better.
