It turns out this was due to a misplaced -[NSView setNeedsDisplay]
call in my custom cell's drawing method.
Every time the cell was drawn, it would set the needsDisplay flag, so
when the window checked the views to see if they needed display, the
table view did.
- (void)drawWithFrame:(
In my app I have a split view (actually an RBSplitView). The left
hand pane contains a table view representing disk volumes, and the
right hand split view contains an NSOutlineView listing files and
directories.
When I update item in the files view, I'm *sometimes* seeing the
volume vie
