the upperpart of the resut.png is a celltable table, the table use a singleselectionmodel.
table.setKeyboardSelectionPolicy(KeyboardSElectionPolicy.BOUND_TO_SELECTION);
table.setSelectoinModel(singleSelectionModel);
singleSelectionModel.setSelected(logs.get(0), true);
table.setFocus(true);
when the resut.png is shown, the first row is really selected, by then when I try to use keyboard upper arrow or down arrow key to select record, the CellTable has no response although I already setFocus to it!!
I found that I must use the mouse to select the record in CellTable first, then the keyboard upper arrow or down arrow key can be used to select recrod, why?
