RichFaces 4.0 issue:
When rich:autocomplete or rich:select are used inside rich:extendeedDataTable, using arrow-keys to move up an down the droplistwill have the unwanted effect that selected row in the underlying table are also changed.
A workaround to this is to use onkeydown="event.stopPropagation();" at the autocomplete. View this post for more information.
