Cannot access Hibernate queries with Woody

[Joel McConaughy]

I'm trying to extend Hugo's hibernate sample to handle queries that 
return multiple rows but have run into a problem.  I can load the query 
results, edit existing rows and delete rows successfully using the 
following flow:

   var factory = 
cocoon.getComponent(Packages.com.displayware.hiblib.PersistenceFactory.ROLE);
   var hs = factory.createSession();
   // NOTE:  users class type is 'java.util.ArrayList'
   var users = hs.find("from User");
   form.load(users);
   form.showForm("simpleuseradmin-display-pipeline");
   form.save(users);
   hs.flush();
   hs.close();
   cocoon.releaseComponent(factory);

However, when the add method specified in this binding snippet is called:

  <wb:on-insert-row>
     <wb:insert-bean classname="com.displayware.hiblib.User"
     addmethod="add" />
   </wb:on-insert-row>
I get the following error:

   org.apache.avalon.framework.CascadingRuntimeException:
   "resource://org/apache/cocoon/woody/flow/javascript/woody2.js", line
   198: uncaught JavaScript exception: at simpleuseradmin
   (file:/home/joel/jakarta-tomcat-5.0.19/webapps/cocoon/StorePortal/flow/useradmin.js,
   Line 35) at
   (resource://org/apache/cocoon/woody/flow/javascript/woody2.js, Line
   198): org.apache.avalon.framework.CascadingRuntimeException:
   InsertBean failed. 

I've traced thru the code and found the exception is thrown in the 
doSave() method in insertBeanJXPathBinding.java at line 109:

          // lookup the named method on the parent
           Method addMethod =
               parent.getClass().getMethod(this.addMethodName, argTypes);
The problem appears to be that the getMethod call requires that the 
argTypes match the exact signature of the corresponsign method.  In this 
case, ArrayList.add(Object o).  However, the binding is passing in the 
class associated with the row com.displayware.hiblib.User which causes 
getMethod() to throw an exception.  The funny thing is that this call 
***would work*** if called directly since com.displayware.hiblib.User is 
derived from Object.

Is there any way to wrk around this?  Thanks.
