All Selected when Move to Next Page

[grenadadoc]

I have a table based on a MS SQL DB.

Very basic datatable at this point, I'll add to it later...

Problem, is that when I run the web application, all appears well. I can select at will from anywhere in the initial table. The row appears selected and the previously selected row is unselected. Problem comes when I either change the number of rows shown in the datatable, or migrate to any other page (using any of the of paginator arrows or direct page number(s). Only way to get back to a selectable datatable, is hit refresh in my browser (FireFox).

Standard FacesConverter stuff follows . . .

Any ideas ? ? ?
