Hi,

I need to validate input when the user enters data on a particular cell 
(caseNumber) in a table view. Not using coredata but data is stored in a 
Postgresql database. Here's what I need to ensure:

1- only digits
2- dont already exists in the database
3- dont already exists in the tableview's datasource
4- need to stay on the cell until valid data is entered.

1- easily done use key-value validation (validateCaseNumber:error:)
2- could be done using key-value validation but this imply opening a new 
database connection (already have one open in master/detail model)
3- this cant be done using key-value validation (no access to the array)

I'm currently using this in a tableview delegate:

- (BOOL)control:(NSControl *)control isValidObject:(id)obj

Which is working fine except that I haven't found a way to customize the error 
string when returning NO in the above method. Am I missing something obvious?

Thanks,

Andre Masse
