I have run up against an apparent 10.6.2 bug in the NSTableView object.
Specifically, if NSTableViewSelectionHighlightStyleNone is set, the tableView
causes Assertion failures and other problems. Below is some code demonstrating
the problem. In any event, I need to emulate the None style for highlight in my
TableView. Does anyone know how to set the highlight color, perhaps, to
clearColor or something with a tiny alpha value so it approximates the None
appearance? I can live with undocumented changes, as the program will run on a
system with a fixed OS, and I can un-hack the NSTableView when the problem is
repaired. (Radar ID# 7588256). If I've done something wrong and this code is
the problem, please tell me, as I'm sort of stuck for now.
Thanks!

Sample code: create a new Cocoa project, drag a tableView into IB, wire it to
your controller. When you add a row, click on the header, then on the tableView
cell. If you comment out the highlightStyle line, this aberrant behavior
disappears.
@implementation MArrayCont
- (void)awakeFromNib
{
mColTitles = [[NSArray arrayWithObjects:@"One", @"Two", nil] retain];
NSArray *mCols = [myTableView tableColumns];
int i=0;
for (NSTableColumn *aCol in mCols)
{
[aCol bind:@"value" toObject:self
withKeyPath:[NSString stringWithFormat:@"arrangedObjects.%@",
[mColTitles objectAtIndex:i]]
options:nil];
i++;
}
[myTableView
setSelectionHighlightStyle:NSTableViewSelectionHighlightStyleNone];
}
- (IBAction)add:(id)sender
{
NSMutableDictionary *mNewRow = [[[NSMutableDictionary alloc] init]
autorelease];
int i=[[self content] count]; // Just provides some
uniqueness to each entry.
for (NSString *aColTitle in mColTitles)
{
[mNewRow setObject:[NSString stringWithFormat:@"%i: %@",i,
aColTitle] forKey:aColTitle];
}
[self addObject:mNewRow];
}
- (void)dealloc
{
[mColTitles release];
[super dealloc];
}
