Forcing a JList to refresh one cell

I have a JList where each item in the list is rendered by a
ListCellRenderer. Among other things, the ListCellRenderer shows a
JProgressBar that is updated by an outside event. The item itself has an
observer to notice that it has been updated, but other than calling
repaint on the whole JList, I can't seem to make it repaint the cell that
changed.
