Hi,
I've got a problem with CoreData validation in my application, that I've
verified against an example delivered by Apple. So it shouldn't be a problem to
reproduce it for everyone:
Steps to reproduce (example project "EventManager" in "CoreData"):
1. Click on tab "Persons"
2. Click on button "Add" -> a new empty line is inserted in the NSTableView
3. Click again on button "Add" -> a second empty line is inserted in the
NSTableView
4. Click on the close button of the window -> EventManager asks to save the
document.
5. Try to save it -> lots of validation errors occurs.
I think the validation should occur every time the user clicks on "Add", so it
isn't possible to add a second empty line. I activated "validates immediately"
for the value bindings of the columns, but it don't work.
The example isn't user friendly this way, is it? And so is my application.
Can someone help to implement the desired functionality?
Marc
