Now I'm really puzzled - how can this method change some internal value of my object???

I'm not sure, but did you try setting the contents of the NSTextStorage instead of calling -setString:?

Yup... I've tried that and it doesn't help

<CODE>
NSTextStorage* ts = [tagsLocsLocationView textStorage];
[ts replaceCharactersInRange:NSMakeRange(0, [ts length]) withString:add];
</CODE>




I've tried using watchpoints but I couldn't get them to run (the hardware rwatch and awatch commands). The normal watch command is pretty useless since it doesn't work out of scope.

Xcode's support for watchpoints is worse than useless. I just do this using the GDB console instead: <http://lists.apple.com/ archives/xcode-users/2004/Oct/msg00275.html>

The post about the watchpoint was real useful... thanks for that. Now I've attached a watchpoint to the variable and I've discovered something _really_ strange: the actual NSString object doesn't change (it's the same pointer!) but for some reason it just reports that it is empty. My wildest guess would be that something is modifying the length of the string - so now I need to add a watchpoint for the count ivar of NSString (if I only knew how to do that). Also it seems really weird I have to resort to such extreme debug techniques to solve a mysterious issue... but I can't find any errors in my code. So thanks to anyone reading this and trying to help.
