Question

我有这个网址：
https://localhost:8181/Platform2/faces/admin/applicationDetails.xhtml?applicantid=16&applicationid=5
当我在浏览器上介绍这个时，我必须登录才能看到这个页面的内容。它应该显示申请人和申请的详细信息（申请人和申请是我的Web maven项目的实体）。问题是，当我这样做时，页面不会检索任何内容。当我再次输入URL时，会显示所需的内容。我的JSF网页是：

}

我在init方法中设置了一个突破点，进行调试，并且第一次没有被调用。当我刷新时，bean被调用并且evertything正常工作。为什么第一次没有结果？

按URL输入页面后未调用Controller
