Hi, I'm a new user en jbpm and I have one problem executing an Action.
Here is the error

and this is the code of the handler:

  | 
  | 
  | 
  | public class SpringInvocationHandler implements ActionHandler
  | {
  | 
  |     private String oResultVariable;
  | 
  |     private String sWSServiceUrl;
  | 
  |     private String sBeanName;
  | 
  |     private String sExtraParam;
  | 
  |     /**
  |      * @see 
org.jbpm.graph.def.ActionHandler#execute(org.jbpm.graph.exe.ExecutionContext)
  |      */
  |     public void execute( final ExecutionContext executionContext )
  |     {
  |         try
  |         {
  |             final Map<Object, Object> oProcessParams =
  |                 (Map) 
executionContext.getProcessInstance().getContextInstance().getVariables();
  | 
  |             if (sExtraParam != null)
  |             {
  |                 String[] aMapContent = sExtraParam.split( "=" );
  |                 if (aMapContent != null && aMapContent.length == 2)
  |                 {
  |                     oProcessParams.put( aMapContent[0], aMapContent[1] );
  |                 }
  |             }
  | 
  |             final String sInstanceId =
  |                 String.valueOf( executionContext.getToken().getId() );
  |             final String sProcessName =
  |                 executionContext.getToken().getNode().getName();
  |             final Service serviceModel =
  |                 new ObjectServiceFactory().create( IWSFrontController.class 
);
  |             final XFire xfire = XFireFactory.newInstance().getXFire();
  |             final XFireProxyFactory factory = new XFireProxyFactory( xfire 
);
  | 
  |             try
  |             {
  |                 final IWSFrontController oSpringClient =
  |                     (IWSFrontController) factory.create( serviceModel, 
sWSServiceUrl );
  |                 final Object oResult =
  |                     oSpringClient.execute( sBeanName, sInstanceId, 
sProcessName, oProcessParams );
  |                 executionContext.setVariable( oResultVariable, oResult );
  |             } catch (Exception e)
  |             {
  |                 e.printStackTrace();
  |             }
  |         } catch (Exception e)
  |         {
  |             e.printStackTrace();
  |         }
  |     }
  | ...
  | 
  | (plus the getter and setter of the fields).
  | 

I try the config-type field and bean whith the same result.
If I see the source code of Action (line 151) the error belong a manual cast 
and later execution of the handler. But if I try this:

  |         String sConf =
  |             "<oResultVariable 
xmlns=\"urn:jbpm.org:jpdl-3.2\">result</oResultVariable><sBeanName 
xmlns=\"urn:jbpm.org:jpdl-3.2\">remaingTimesvc</sBeanName><sWSServiceUrl 
xmlns=\"urn:jbpm.org:jpdl-3.2\">http://10.0.0.126:8080/services/WSFrontController</sWSServiceUrl>";
  |         Object o =
  |             new FieldInstantiator().instantiate( 
jbpm.SpringInvocationHandler.class, sConf );
  |         ActionHandler o1 = (ActionHandler) o;
  | 
works fine.

The jbpm version is 3.2.1.

Any idea?
Thanks in advice.
