import oracle.adf.view.rich.context.AdfFacesContext;

public class SetValueSmcBean {
    private RichSelectManyChoice selectMcBind;

    public SetValueSmcBean() {
    }

    /**Methos to set selected values in SelectManyChoice
     * @param actionEvent
     */
    public void setSelectedValuesAction(ActionEvent actionEvent) {
        ArrayList listVal = new ArrayList(20);
        //Add DepartmentId to list that you want to set as selected
        listVal.add(101);
        listVal.add(102);
        // Set this List as value using component binding
        selectMcBind.setValue(listVal.toArray());
        //Refresh Component on page (partial target)
        AdfFacesContext.getCurrentInstance().addPartialTarget(selectMcBind);
    }

    public void setSelectMcBind(RichSelectManyChoice selectMcBind) {
        this.selectMcBind = selectMcBind;
    }

    public RichSelectManyChoice getSelectMcBind() {
        return selectMcBind;
