Thanks for the answer. I'll avoid the binding, as you suggest, but it is not without a loss of elegance in the code. If you select many rows and use a listener you do a roundtrip for every selection (to save the keys of the selected rows somewhere) , while you actually need only the last one, when you activate the command (in instance, when you click the "delete" button after having selected the delatable rows). But the real question is: Is this problem in the binding of the trinidad table something concerning this specific components or is it something that affects other components and/or the whole seam/trinidad cohabitation? The binding problem would affect even a standard h:dataTable or the rich:dataTable components (even if you do not need to bind a standard datatable as you do not have any information to collect)?
