Java Development Tools

I have a table connected to a detail PayLoanView and one of the fields has an LOV as defined as per below snapshot.

]

the LOV field is a table column.

Requirement

I used to filter the LOV programmatically like below.

| | public void filterLoanItemTypes(LaunchPopupEvent launchPopupEvent) { |
| | DCBindingContainer binding = BindingsUtil.getBindingContainer(); |
| | FacesCtrlLOVBinding lov = (FacesCtrlLOVBinding)binding.get("PitmDesc"); |
| | lov.getViewObject().setWhereClause("ITEM_TYPE = 3"); |
| | } |

But I get the NPE exception although I have defined the an attribute variable to for the attribute containing the LOV.

on line lov.getViewObject().setWhereClause("ITEM_TYPE = 3");

lov is null apparently ... then defined an attribute binding for it ....like below.

But then I got the below error:

Caused by: java.lang.ClassCastException: oracle.adfinternal.view.faces.model.binding.FacesCtrlAttrsBinding cannot be cast to oracle.adfinternal.view.faces.model.binding.FacesCtrlLOVBinding

What is the solution programmatically ...???
