JDeveloper 12c Oracle ADF Get the selected Value from LOV

LOV Fields are: fnameId and lnameId
Button: Clear
Create Managed Bean and write the following code:

public void showLOVValues()  
{
FacesContext facesContext = FacesContext.getCurrentInstance();
               UIViewRoot root = facesContext.getViewRoot();
               ComponentReference<RichInputListOfValues>
           richText1  = ComponentReference.newUIComponentReference((RichInputListOfValues)root.findComponent("fnameId"));
        RichInputListOfValues FinputText1  = richText1.getComponent();
     
        ComponentReference<RichInputListOfValues> richText2  =
        ComponentReference.newUIComponentReference((RichInputListOfValues)root.findComponent("lnameId"));
        RichInputListOfValues LinputText2  = richText2.getComponent();
     
System.out.println("**** First LOV String is :"+FinputText1.getValue());
        System.out.println("**** Second LOV String is :"+LinputText2.getValue());
}

Properties:
AutoSubmit = True
PartialTrigger = ClearButton for both Lov fields
