How to keep the filterBy value of rich:datatable in session scope?

Is it p开发者_JAVA百科ossible to keep the filterBy value of a rich:datatable rich:column filterBy="..." in SESSION scope?

Yes, use el expression pointing to property of bean that is put in session scope.

<rich:datatable ...>
 <rich:column filterValue="#{yourSessionBean.filterByProperty}" ... >
...

I'm assuming you want to store filterValue not filterBy.
