Unacceptable type of value for to-one relationship

[emilpedersen]

When I try to edit and TimeEntry i get this error:
Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: 'Unacceptable type of value for to-one relationship: property = "project"; desired type = TimeTarget.Project; given type = TimeTarget.Project; value = (entity: Project; id: 0x174426160 x-coredata://6B81EA38-15B7-4C85-ADB5-6640EE31DF5D-9088-000002BEECC9720D/Project/p254230CF-A9CD-4CAD-B47F-19DFBA054081 ; data: {

color = 0;
defaultHourRate = 0;

}).'

And same when I try an edit an Project:
Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: 'Unacceptable type of value for to-one relationship: property = "client"; desired type = TimeTarget.Client; given type = TimeTarget.Client; value = (entity: Client; id: 0x174621ac0 x-coredata://17D56827-FF19-4DDD-8161-E4C930BC4398-9102-000002BF85C10C71/Client/p686DBB54-ACC5-4313-8369-2DF9B8003E4B ; data: {
billable = 0;
color = 0;
defaultHourRate = 0;
name = Klkj;
projects = (
"0x170432e00 x-coredata://17D56827-FF19-4DDD-8161-E4C930BC4398-9102-000002BF85C10C71/Project/p9E6EA418-FF51-492C-84ED-575A76659490",

);
}).'

The client I can edit / save without problem. It first happens when I have closed the app and reopened the app again.

This might help.

Can't get it to work.
It works without CKSIncrementalStore. With CKSIncrementalStore it only works until I restart the app.

I have checked. I think this is not a bug. I checked by changing the model with to one and a to many inverse relationship. I also tried re starting the demo app several times and changing values for to many and to one relationships. All worked fine. I have updated the demo btw. You can also try out it over there.
Please double check your CoreData model. This helped me too. Please also check that if you are using the same instance of NSManagedObjectContext to modify the objects.

Sorry you were right this was a CKSIncrementalStore bug. Check the latest build now and post feedback here :)
