[javaflow] AssertionViolatedException when deriving classes

Hi List,

during some work with javaflow (actually I am triying to adopt the  
[1] CocoonAndHibernateTutorial) I came across the following problem.  
To create an abstract class providing a hibernate session I wrote the  
following class:

    abstract class AbstractHibernateContinuable extends  
AbstractContinuable {
       protected Session hs = null;

       protected AbstractHibernateContinuable() throws  
ProcessingException {
          super();
          // initialize hs and do some other stuff
       }
    }

My actual flow method is doTest() in the following class:

    public class JavaflowTest extends AbstractHibernateContinuable {
       private Session hs = super.hs;
	
       public JavaflowTest() throws ProcessingException {
          super();
       }
	
       public void doTest() {
          List l = this.hs.createQuery("select f from Foo f").list();
         // process list and sendPage
       }	
    }

The code above works fine, however to me it seems that the line

    private Session hs = super.hs;

is "redundant" but if I try to _run_ the code (_compilation_ works  
fine) without it I get the following error:

    org.apache.bcel.verifier.exc.AssertionViolatedException: INTERNAL  
ERROR: Field 'hs' not found?!?

(I guess BCEL is not checking the inheritance hierachy for the  
variable). Is there a "cleaner" way to do this or should a take a  
completely different approach? I am looking forward for any input on  
this proplem - please also tell me if there is no way to do it  
without the redundancy.

Thanks in advance

Benjamin

If you don't ming please create a testcase and file a bug for http:// 
commons.apache.org/sandbox/javaflow at
