But the Manual Bindings sample code you provide binds a controller to

That shouldn't make any difference -- see below.
I'm trying to bind with a NSTableColumn that I create programatically.
I added a logging to your sample code to log the exposed bindings of
your NSTableColumn and I got this:
( fontSize, maxValue, fontName, minWidth, fontFamilyName, minValue,
font, fontItalic, headerTitle, textColor, value, editable, maxWidth,
width, fontBold )
That's dramatically different from the set of bindings I get from a
programatically created NSTableHeader:
( fontSize, fontName, minWidth, fontFamilyName, headerTitle, font,
fontItalic, editable, maxWidth, width, fontBold )
Am I missing something?
I added a formatter to my table column. And I'm not sure why you're
comparing with NSTableHeader?
Here's some code to add a new table column with bindings:
- (void)addTableColumnWithIdentifier:(NSString *)ident
{
NSTableColumn *newColumn = [[NSTableColumn alloc]
initWithIdentifier:ident];
[tableview addTableColumn:newColumn];
[newColumn release];
[[newColumn headerCell] setTitle:
NSLocalizedStringFromTable(ident, @"TableHeaders", nil)];
[[newColumn dataCell] setDrawsBackground:NO];
if (...)
{
NSNumberFormatter *numberFormatter =
[[[NSNumberFormatter alloc] init] autorelease];
[numberFormatter setFormat:@"$#,##0.00"];
[[newColumn dataCell] setFormatter:numberFormatter];
[[newColumn dataCell] setAlignment:NSRightTextAlignment];
}
NSMutableDictionary *bindingOptions=[NSMutableDictionary
dictionary];
[bindingOptions setObject:[NSNumber numberWithBool:YES]
forKey:NSValidatesImmediatelyOption];
// ...
NSString *keyPath = [NSString
stringWithFormat:@"arrangedObjects.%@", ident];
[newColumn bind: @"value" toObject: productArrayController
withKeyPath:keyPath options:bindingOptions];
}
