1. You don't say what "fail" means. A crash? What error code? What stack trace?
2. This is all moot, because, as the leading underscore shows,
_dataSourceValueForColumn:row: is a private method. It is not meant to be
called by anyone but Apple. It is likely that only Apple knows what the
preconditions and postconditions for calling it are; and they can change those
conditions at any time.
I Googled _dataSourceValueForColumn:. Have you noticed that virtually all the
hits have titles like "Arbitrary Crashes," "Bug," "Consistently crashes,"
"issue," "crashes everytime," "Crash in my... data source?"
3. Now that I re-read your message, you don't say whether you're implementing
_dataSourceValueForColumn:row: or calling it; or even whether you're using it
at all. Even if you're just implementing it, the principle holds: You don't
know what the method is required to do, and you don't know what it will be
required to do in 10.6.3. (Note for archives: The current version of Mac OS X
is 10.6.2.)
What are you trying to accomplish, and why do you think it cannot be done with
supported API?
