是否可以“灰出” ah：selectBooleanCheckbox？

Question

Currently I have conditions in my render attribute that decide whether the checkbox is displayed or not. 目前，我的渲染属性中有条件决定是否显示该复选框。 Instead, I want the conditions to dictate whether the checkbox is clickable or greyed out (to indicate the user does not have permission to click it). 相反，我希望条件决定该复选框是可单击的还是灰色的（以表明用户无权单击它）。

I am a complete noob to JSF. 我对JSF完全陌生。

try something like this 尝试这样的事情

import java.io.Serializable;

import javax.faces.bean.ManagedBean;
import javax.faces.bean.ViewScoped;



@ManagedBean
@ViewScoped
public class MyMB implements Serializable{

    /**
     * 
     */
    private static final long serialVersionUID = 1L;

    private boolean disabledCheckbox = false;

    public void toggle(){
        this.disabledCheckbox = !this.disabledCheckbox;
    }

    public boolean isDisabledCheckbox() {
        return disabledCheckbox;
    }

    public void setDisabledCheckbox(boolean disabledCheckbox) {
        this.disabledCheckbox = disabledCheckbox;
    }

}

and 和
