> ScrollableDataTable uses row indexes to store selection on client side, this causes a problem if bound data changes (new rows added or removed by another parallel transaction).
> For example. 
> First user opens a page. ScrollableDataTable has 3 records.
> In a parallel transaction  inserts a second user a new record (as a first row = on index 0)
> First user selects first row and execute some action. Selection object on the server-side returns a row, which was added by the secon user, and not the row which was realy selected by first user.
> i also added a test-project: simple page with SDT and two buttons "Selection" (shows current selection) and "Add Row" (inserts a new row on position 0)
> to reproduce a bug select a row, click "add row" and then "selection", you'll see that selection is wrong.
> selection must be saved not as indexes on client side, but as rowkeys(which can be defined as a real IDs of records in DB).
