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?
