始终将backing bean布尔属性设置为false

Question

我有一个项目列表，我在网页上显示其内容。每个项目都有一个布尔值来表示它是否已被选中。下面给出了. xhtml文件和后备bean项目。问题是每次我选择或取消选择网页中的布尔按钮时，它总是将后备bean中的布尔属性设置为false。

.xhtml

<p:outputPanel layout="inline">
  <p:repeat id="projectSelect" 
            value="#{checkoutRulesBean.projectList}" 
            var="project">
    <p:selectBooleanButton id="project"
                            value="#{project.selected}"
                            onLabel="#{project.name}" 
                            offLabel="#{project.name}" 
                            onIcon="fa fa-check"
                            offIcon="fa fa-square-o"
                            style="margin: 5px; padding: 5px;" >

       <p:ajax listener="#{checkoutRulesBean.toggleProjectSelection()}"
             process="@this"
             update="@(.project-boards-table)"/>

    </p:selectBooleanButton>
  </p:repeat>
</p:outputPanel>

Project.java（背豆）

public class Project implements Serializable{
    
    private List<BoardCheckoutRules> boardCheckoutList = new ArrayList<>();
    private Boolean selected = true;
    private String name;
    
    /**
     * Creates a new instance of Project
     */
    public Project() {
    }
    
    public Project(String name){
        this.name = name;
    }


    public List<BoardCheckoutRules> getBoardCheckoutList() {
        return boardCheckoutList;
    }

    public void setBoardCheckoutList(List<BoardCheckoutRules> boardCheckoutList) {
        this.boardCheckoutList = boardCheckoutList;
    }

    public Boolean getSelected() {
        return selected;
    }

    public void setSelected(Boolean clicked) {
        PayaraLogger.logDebug(this.name + " has been " + ((clicked) ? "selected" : "unselected"));
        this.selected = clicked;
    }
   
    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }    
}

我发现了问题所在。selectBooleanButton应该包装在一个
