Displaying newly added row in a table

With the new release  of jdeveloper (PS2) There was a table that I thought wasn’t refreshing after adding a new row to it. It actually was refreshing but when the table refreshed, the scroll bar moved slightly but not noticeably down so that that the added row was scrolled off the top of the screen so that the table looked like it hadn’t changed. I discovered that there is a property of the table “DisplayRow” that can contain "default", "first", "last" or selected. The dropdown shows that selecting “default” should be the same as selecting “first” but I found this not to be the case. When I changed it from “default” to “first” it fixed the problem and now the added row is displayed at the top of the table after refreshing without moving the scrollbar.
