Problem running Object Value Selector

Question

Hi,
We have implemented OVS for GetFlightList BAPI. We are able to get the data on the OVS selector. But once we click on a particular record of the table, the value is not passed to the base control and we get <b>ClassCastException</b> in applyResult() method of the listener.
The code is pasted below.
public void applyResult(IWDNodeElement applicationNodeElement,
     IWDNodeElement queryOutputNodeElement) {
try
<b>IPrivateOVS_testView.IFlight_dataElement ovsCallerNodeElement =(IPrivateOVS_testView.     IFlight_dataElement) applicationNodeElement;</b>
The exception thows on this line of the code.
Any help?
regards,
Deepika

I am still getting the same Exception.I am explaning the scenerio:
I created a set of Flight_data attributes in the custom controller and mapped to a similar set in the view controller to fix the error.The listener is implemented in the Custom controller.On selecting a row from the OVS table i get the CastClass Exception in the applyResult()method of the listener at the following point of code:
<b>IPublicTestOVS_Custom.IFlight_dataElement ovsCallerNodeElement =
     (IPublicTestOVS_Custom.IFlight_dataElement)
     applicationNodeElement;</b>
The exception is given below:
<i>java.lang.ClassCastException
