Thanks Quincey - here's the code:
[[resultsTableView
tableColumnWithIdentifier:@"startDateColumnIdentifier"] bind:@"title"
toObject:resultsArrayController
withKeyPath:@"arrangedObjects.topic.taskStartStringForPanel" options:nil];
If the cell for the column is an NSTextFieldCell, and the binding is "value",
this displays the string successfully, but when I change to an NSButtonCell and
try to bind "title", I get the error message.
