setting the selection of a tableView

I have a htmlb:tableView with

selectionMode = "MULISELECT"

In DO_HANDLE_DATA, I read the user's selection, which works fine. The selection is stored in the field "filtered" of the table.

Now, when I return to the page, I want to restore the selection from the last time.

I thought, I could do this with

selectedRowKey = "filtered"

but this does not work (no lines are selected).

What should I do? Should I use selectedRowIndexTable or

selectedRowKeyTable. Those two attributes seem to exist, but they are not documentet in my system (620) yet.
