Hi I am trying to get my core data app syncing to iCloud so that multiple devices can be used.
I just started a new iCloud account for testing and installed my app on both devices. I have enabled my app for iCloud using instructions at this link Using CoreData with icloud and by also comparing my app to apple's coreDataRecipes example code.
I was not getting any syncing occurring so I did some logs to find out what was occurring. After adding an object to core data from iPad A i received the following log on iPad B which was connected to the computer.
2012-01-20 17:35:35.979 My-App[407:22d7] AppDelegate Merge Changes From iCloud Notifications
2012-01-20 17:35:35.980 My-App[407:22d7] AppDelegate managed Object Context
2012-01-20 17:35:35.981 My-App[407:707] Block redirecting to method merge icloud changes for context
2012-01-20 17:35:35.981 My-App[407:707] AppDelegate Merge icloud changes for context
Then I get this error

, the baseline will not be adopted.
It would be greatly appreciated if someone could let me know why I am getting a conflict due to the (null) values and where I can look to resolve this.
Thanks
ps. I have changed the seen in the log app name, unique identifier and company name just for this post.
EDIT Syncing is occurring however it seems to be delayed.
