After I set the editedItemPosition from the arrow key pressed, I refresh the dataprovider, because that seemed to make it move the focus properly. For the 'selectAll' function, I perform an itemUpdated on the arraycollection after setting the new item in it, and then refresh the dataprovider, since I didn't see the new data in the grid if I didn't. Is there a better way (i.e. one that works) that I should do to get the cell to navigate properly with the arrow keys and the new data to be reflected in the row?
