How to get selected value from SelectOneChoice

Question

Hi,
I'm facing a problem to get selected value from SelectOneChoice. I have valueChangeListener event on a (SelectOneChoice)item. After user makes a choice I want to store selected value in a bean property to pass it to a method.
For example List item shows dname from dept table after user makes a choice I want to get deptno and populate into bean which I use to pass into my method.
If I use valueChangeEvent.getNewValue() I always get negative value instead I want deptno selected. Sample code pasted below.
public void setDeptno(ValueChangeEvent valueChangeEvent) {
BindingContainer b = getBindings();
OperationBinding oB = b.getOperationBinding("setDeptno");
//Checking instance of because same method is called from another text inputText item.
if (valueChangeEvent.getSource() instanceof CoreSelectOneChoice){
CoreSelectOneChoice cN = (CoreSelectOneChoice)valueChangeEvent.getSource();
if (columnName.getId().toString().equals("deptDname")){
JSFUtils.setManagedBeanValue("dept.deptDeptno",valueChangeEvent.getNewValue());
}

if your selectOneChoice has value equal to #{bindings.deptno} bound to the iterator Dept1Iterator,
then the backing code will look more like
                public void setDeptno(ValueChangeEvent valueChangeEvent) {
                    BindingContainer b = getBindings();
                    OperationBinding oB = b.getOperationBinding("setDeptno");
                    //Checking instance of because same method is called from another text inputText item.
                    if (valueChangeEvent.getSource() instanceof CoreSelectOneChoice){
                        CoreSelectOneChoice cN = (CoreSelectOneChoice)valueChangeEvent.getSource();
                    if (columnName.getId().toString().equals("deptDname")){
                        FacesContext ctx = FacesContext.getCurrentInstance();
                        Application app = ctx.getApplication();
                        ValueBinding bind = app.createValueBinding("#{bindings.Dept1Iterator.currentRow}");
                        Row row = (Row)bind.getValue(ctx);
                        JSFUtils.setManagedBeanValue("dept.deptDeptno", row.getAttribute("deptno"));
                } I haven't tested it, so it could perfectly not work at all
