Primefaces DataTable 过滤警告

Question

我使用的是 primefaces 3.5，我的表单中有一个 DataTable 组件。

当我尝试使用像 this 这样的过滤器时primefaces 展示，我收到此警告消息:

WARNING: DataTable j_idt7:j_idt8:someList has filtering enabled but no filteredValue model reference is defined, for backward compatibility falling back to page viewstate method to keep filteredValue. It is highly suggested to use filtering with a filteredValue model reference as viewstate method is deprecated and will be removed in future.

有人能帮忙吗？

See the user guide on page 133 'Data Filtering' in the chapter dataTable. There is a new attribute filteredValue that should point to a List in a ViewScoped managed bean to store the filtered values the user typed in.
