You nested the <p:ajax>inside a <p:column>. The <p:ajax>requires to be nested in a component implementing the ClientBehaviorHolderinterface. However, the Columncomponent classbehind <p:column>does not implement it. The DataTablecomponent classbehind <p:dataTable>implements it.
你嵌套了<p:ajax>里面的<p:column>. 该<p:ajax>要求被嵌套在实现的组件ClientBehaviorHolder接口。但是后面的Column组件类<p:column>并没有实现。后面的DataTable组件类<p:dataTable>实现了它。
You should be nesting <p:ajax>inside <p:dataTable>instead:
你应该嵌套<p:ajax>在里面<p:dataTable>：
<p:dataTable ...>
<p:ajax ... />
<p:column ...>
...
</p:column>
</p:dataTable>
Exactly as demonstrated on their showcase site. In other words, your statement
与他们的展示网站上展示的完全一样。换句话说，你的陈述
althought i copied the same example shown in showcase
虽然我复制了展示中显示的相同示例
is actually not true.
事实并非如此。
