getContentHandler??

[Per Eckerdal]

I have a problem. I really don't know if its my fault or if its xalan:s 
fault. I get a strange exception and with some debugging I've found the 
error is this, look at the code:

      try {
          
System.setProperty("org.xml.sax.driver","org.apache.xerces.parsers.SAXParser"); 

          
System.out.println("------------------------------------------------------------------"); 

          TransformerFactory tFactory = 
javax.xml.transform.TransformerFactory.newInstance();
          javax.xml.transform.sax.SAXTransformerFactory saxTFactory = 
((javax.xml.transform.sax.SAXTransformerFactory) tFactory);
          XMLFilter xmlf = saxTFactory.newXMLFilter(new 
javax.xml.transform.stream.StreamSource(new 
FileInputStream("c:\\programmering\\xml\\test\\hello.xsl")));
          Serializer ser = 
SerializerFactory.getSerializer(OutputPropertiesFactory.getDefaultMethodProperties("html")); 

          System.out.println("Before change, xmlf.getContentHandler() 
== "+xmlf.getContentHandler());
          System.out.println("Setting ser.asContentHandler() 
("+ser.asContentHandler()+") as ContentHandler for xmlf via 
setContentHandler");
          xmlf.setContentHandler(ser.asContentHandler());
          System.out.println("After change, xmlf.getContentHandler() == 
"+xmlf.getContentHandler());
          
System.out.println("------------------------------------------------------------------"); 

      } catch (Exception e) {
          e.printStackTrace();
      }
The output I get is:
------------------------------------------------------------------
Before change, xmlf.getContentHandler() == null
Setting ser.asContentHandler() 
([EMAIL PROTECTED]) as ContentHandler for 
xmlf via setContentHandler
After change, xmlf.getContentHandler() == null
------------------------------------------------------------------

Is this a bug or have I misunderstood something?
I do not have much experience in xml transformation, so I've maybe done 
a fault almost too simple for you to answer, but  getContentHandler I 
think should return the ContentHandler set in the previous line of  
code, not null, or  what have I done wrong?

I would be happy for an answer
