Set values in af:selectManyChoice programmatically - Oracle ADF

This post is about a very common question
How to set selected values in af:selectManyChoice component ?
Sometimes we need to set some values in selectManyChoice component on some action

In this post i am using Departments table of HR Schema to create selectManyChoice (Multiple Selection)
Just drag and drop Departments viewObject as ADF Select Many Choice
see- Using Multiple Selection (selectManyListbox & selectManyCheckbox component) in ADF


(Jdev Version- 12.1.3)
dropped a button on page and on this button action ,  setting values in component
See this simple managed bean code -




import java.util.ArrayList;

import javax.faces.event.ActionEvent;

import oracle.adf.view.rich.component.rich.input.RichSelectManyChoice;
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;
    }
}
