如何从服务器生成SelectManyCheckbox（素面）？

Question

I need to generate dynamically some components from the server and I have a problem with SelectManyCheckbox. I need to add a list of selectitems into it but there is no such method available. Maybe someone can help me, maybe I choose wrong direction. Example:

SelectManyCheckbox checkbox = new SelectManyCheckbox();
List<SelectItem> items

items - the list that must be displayed as selectItems.

Answer 1

If I understood you correctly, you want to add them programmatically. The key is to add them as children. One way to do it could be like this:

List<SelectItem> items; //Your items
SelectManyCheckbox checkbox = new SelectManyCheckbox();
UISelectItems selectItems = new UISelectItems();
selectItems.setValue(items);
checkbox.getChildren().add(selectItems);

Answer 2

The value of <f:selectItems of a <p:selectManyCheckbox can be populated with objects of SelectItem :

Value expression pointing at any Collection or array. The member elements may be instances of SelectItem or any Java Object.

Example

page.xhtml

<p:selectManyCheckbox>
    <f:selectItems value="#{bean.items}"/>
</p:selectManyCheckbox>

Bean.java

import javax.faces.model.SelectItem;
import javax.faces.view.ViewScoped;
import javax.inject.Named;
import java.util.ArrayList;
import java.util.List;

@ViewScoped
@Named
public class Bean {

    public List<SelectItem> getItems() {
        return new ArrayList<>();
    }
}
