Assigning default search values for LOV Search and Select popup

Values for search attributes on LOV Search and Select popup can be preset using a launchPopupListener method

<af:inputComboboxListOfValues id="inpClv2"
    popupTitle="Search and Select: #{bindings.StateProvince.hints.label}"
    value="#{bindings.StateProvince.inputValue}"
    label="#{bindings.StateProvince.hints.label}"
    model="#{bindings.StateProvince.listOfValuesModel}"
    required="#{bindings.StateProvince.hints.mandatory}"
    columns="#{bindings.StateProvince.hints.displayWidth}"
    shortDesc="#{bindings.StateProvince.hints.tooltip}"
    launchPopupListener="#{backingBeanScope.lovBean.stateLaunchPopupListener}"> 
</af:inputComboboxListOfValues>

Suppose if we want to preset CountryId in Search and Select popup for State LOV, the launchPopupListener code will look like:

public void stateLaunchPopupListener(LaunchPopupEvent launchPopupEvent)
{
    UIXInputPopup lovComponent = (UIXInputPopup)launchPopupEvent.getSource();
    ListOfValuesModel model = lovComponent.getModel();
    if (model != null)
    {          
        QueryDescriptor queryDesc = model.getQueryDescriptor();
        ConjunctionCriterion conCrit = queryDesc.getConjunctionCriterion();
        List<Criterion> criterionList = conCrit.getCriterionList();
        for (Criterion criterion: criterionList)
        {
            AttributeDescriptor attrDesc = ((AttributeCriterion) criterion).getAttribute();
            if (attrDesc.getName().equalsIgnoreCase("CountryId")) 
            {
                List values = ((AttributeCriterion) criterion).getValues();
                values.set(0, "US"); 
            }
        }
    }           

}
