However, if I change composite component this way:

Adding a <h:panelGroup> in <f:facet> solves the problem. Bad tree indexing or am I missing something? I'm using mojarra 2.1.3 and PrimeFaces 3.0.M4-SNAPSHOT under Glassfish 3.1.1.

添加一个在解决了这个问题。不好的树索引还是我漏掉了什么?我使用的是mojarra 2.1.3和PrimeFaces 3.0。M4-SNAPSHOT Glassfish 3.1.1。

According to JSF2 documentations, The <f:facet> tag can have only one child. If you have many elements which you want to nest inside a facet tag, you should first wrap them in some other container like <h:panelGroup>, then put that single parent container in the <f:facet>.

根据JSF2文档，标签只能有一个孩子。如果您想在一个facet标记内嵌套许多元素，那么您应该首先将它们封装在其他容器中，比如，然后将这个单独的父容器放在中。

Abstract:

文摘:

The f:facet tag signifies a nested component that has a special relationship to its enclosing tags. For example, stating that the "header" of a table is to be provided by a JSF component. This element adds the component represented by the JSF action in its body as a facet with the specified name to the component represented by the closest JSF component parent action element. This tag only allows one component to be nested whithin itself. To use multiple component as a facet, create them as children of a simple container component. For example, nest the corresponding HTML library component actions within the body a panelGroup component.

f:facet标记表示一个嵌套组件，它与它的封闭标记有特殊关系。例如，声明表的“头”是由JSF组件提供的。此元素将JSF动作所表示的组件添加为一个包含指定名称的facet，该组件由最近的JSF组件父操作元素表示。这个标签只允许一个组件被嵌套。要使用多个组件作为一个方面，创建它们作为一个简单容器组件的子组件。例如，在body内嵌套相应的HTML库组件动作，即panelGroup组件。
