I have several tabs and one of the tabs uses rich:extendedDataTable. If sortBy is clicked in the page where table is used and if I navigate to another page, it looks for the bean of the old page and throws an error saying that sortyBy of the column is undefined.

E.g. If I use sortBy on userId in tab1 (where the column must have sortBy="#{data.userId}") and then I click on tab2, it looks for the data.userId and throws an error. I am using Richfaces version 3.2.2SR1.

Can anyone help me on this?

Here is the complete trace:
