Previous problem solved:
A few weeks ago, I posted a question pertaining to trouble I was having when tableView column header cell titles contained period (.) characters. After working around it, I recently discovered the source of my problem and I figured I'd post just in case anyone else stumbled down this same path.
In brief, I have an NSTableView to which the user can add user-titled columns. I bound the tableView's columns to a controller programmatically. This was the root of my trouble. I chose to use the column title strings as the keys for the binding, like this:
<code>
[aTableColumn bind:@"value" toObject:myDataController withKeyPath:[NSString stringWithFormat:@"arrangedObjects.%@", [myTitleArray objectAtIndex:i]] options:nil];
</code>
Of course, when the %@ in the formatted string was replaced with a column title containing a period, the key acquired an incorrect dot-syntax appendage. For whatever reason, that error then caused several messages regarding object validation to occur, convincing me that I had accidentally requested object validation.
In any event, the error was entirely mine, and periods can easily coexist with column titles as long as I do something like [[myTitleArray objectAtIndex:i] stringByReplacingOccurrencesOfString:@"." withString:@""].
