Jsf 渲染不'；不能在dataTable中工作

我在jsf上的代码中有4个ifs的问题。我必须检查3个参数，当它正常时显示相应的消息。为什么它不起作用？在dataGrid中，它在c中工作：当

<h:outputLabel value="#{msg.deleted}" class="delete" rendered="#{((!advertisement.isStarted) and (!advertisement.isActive) and (!advertisement.isFinished))}"/>
<h:outputLabel value="#{msg.done}" class="done" rendered="#{((advertisement.isStarted) and (!advertisement.isActive) and (advertisementisFinished))}"/>
<h:outputLabel value="#{msg.realize}" class="realize" rendered="#{((advertisement.isStarted) and (advertisement.isActive) and (!advertisement.isFinished))}"/>
<h:outputLabel value="#{msg.open}" rendered="#{((!advertisement.isStarted) and (advertisement.isActive) and (!advertisement.isFinished))}"/>

是的，我在实体类中有isStarted、isFinished和isActive。在datagrid的另一端，它可以工作。我用它来显示操作的状态。等等，我在实体中有公共布尔getIsActive（）{return isActive；}公共布尔IsIsIsStarted（）{return isStarted；}公共布尔IsIsIsFinished（）{return isFinished；}数据表在哪里？对应的bean在哪里？请阅读和

public boolean isIsActive() {
    return isActive;
}

public void setIsActive(boolean isActive) {
    this.isActive = isActive;
}

public boolean isIsStarted() {
    return isStarted;
}

public void setIsStarted(boolean isStarted) {
    this.isStarted = isStarted;
}

public boolean isIsFinished() {
    return isFinished;
}

public void setIsFinished(boolean isFinished) {
    this.isFinished = isFinished;
}
