jsf - 无法在删除确认对话框中显示对象详细信息

Question

这是我在数据表列中的命令按钮，它的工作是删除关联的行对象:

   <p:column style="width:6%;text-align:center"
   headerText="Delete">
    <p:commandButton icon="ui-icon-close"
     title="Delete release #{release.name}"
     actionListener="#{releaseBean.deleteRelease(release)}"
     process="@this" update=":display :form2:releaseList">
        <p:confirm
          header="Confirm deleting release #{release.name}"
          message="Are you really sure you want to delete release #{release.name}?"
          icon="ui-icon-alert" />
    </p:commandButton>
   </p:column>

我希望在删除确认消息中显示发布名称(Are you really sure you want to delete release "XYZ"?)。但问题是发布名称“XYZ”不是也不显示在 <p:confirm> 的标题中消息中都没有；但它显示在 <p:commandButton> 中标题。

我做错了什么？谢谢。

编辑:

我尝试修改 commandButton 并添加 setPropertyActionListener :

    <p:commandButton icon="ui-icon-close"
         title="Delete release #{release.name}"
         actionListener="#{releaseBean.deleteRelease(release)}"
         process="@this" update=":display :form2:releaseList">
         <f:setPropertyActionListener
         target="#{gestionReleaseBean.selectedRelease}"
         value="#{release}" />            
         <p:confirm
              header="Confirm deleting release #{release.name}"
              message="Are you really sure you want to delete release #{release.name}?"
              icon="ui-icon-alert" />
    </p:commandButton>

我在 bean 中添加了属性 selectedRelease它是 getter/setter。

没用...

如果您不介意一些额外的代码行，那么您可以按如下方式实现，

首先在数据表外放置一个对话框

<p:dialog modal="true" header="Confirm" widgetVar="wgc" >
 <h:outputText id="msg" />
 <h:inputHidden id="idh" value="#{releaseBean.id}" />
 <p:commandButton value="Delete" action="#{bean.delete()}" />
 <p:commandButton value="Cancel" type="button" onclick="PF('wgc').hide()" />
</p:dialog>

在你的 javascript 部分添加这个

function confirm(id,name){
 document.getElementById('msg').innerHtml='Are you sure to delete ' +  name;
 document.getElementById('idh').value=id;
 PF('wgc').show();
}

然后在数据表中删除按钮

<p:commandButon type="button" 
                value="Delete" 
                onclick="confirm(#{release.id},'#{release.name}')" />
