我正在使用最新的 PrimeFaces (3.6-SNAPSHOT)。在火狐上测试。
我一直在尝试隔离问题。这是我发现的。
我的页面设计如下：一个TabView - 它的每个选项卡都包含另一个 TabView，它的每个选项卡都包含一个Layout。
问题是在某些选项卡上，布局没有出现。当我使用 PrimeFaces 3.4.2 编译时，无论我是否单击另一个选项卡，然后单击返回缺少布局的选项卡，都不会显示丢失的布局。但是，当我使用 PrimeFaces 3.6-SNAPSHOT 编译时（单击另一个选项卡，然后单击缺少布局的选项卡） - 出现缺少的布局。疯了吧？
真正疯狂的是，当我看到布局不可见时，我用 firebug 检查它，发现它的 HTML 与它显示时的不同......
怎么可能？？我以为我得到了一个静态页面（带有一些 Javascript，但 HTML 本身仍然没有变化）。这超出了我的理解。
例如，重新启动 Firefox，加载页面并尝试按以下顺序单击选项卡：(1,1) (1,2) (1,3) (1,4) 一切正常。现在单击选项卡 2（标题）。您是否看到选项卡 (2,1) 中的布局消失了？现在单击 (2,2) 并返回 (2,1) - 现在布局就在那里。奇怪的东西。
知道发生了什么吗？
它可能与这个问题有关： https ://stackoverflow.com/questions/13978438/primefaces-layout-not-working-inside-tabview
这是代码，您可能想尝试一下。
