Sync problems with mobile account

[ftestuz]

With Yosemite, I installed the Server version on my MacMini and my account on my MBPro is a mobile account.
For a new project, I decided to use BSManagedDocument. I want to use CoreData and image file for my document, so the package format is good for me.
I'm in the first step and, for now, my program don't save anything inside the package. I almost did no subclassing of BSManagedDocument.
But, when I change the document on my MB, I get a sync problem message when the mobile account try to synchronize with the MacMini. I don't have this problem when I change the document on the server, the change is correctly synchronized to the MB.
I never encounter this problem elsewhere. I don't think it's a problem with my code as:

• if I change the superclass of my document class to NSPersistentDocument, the problem go away
• I have the same problem with the Sandvox package document.

Below is the error window message and the sync log (I also have the verbose sync log, but it's quite long).

Hi @ftestuz, iCloud sync is not something I've attempted to support so far in BSManagedDocument, but I know others have. Hopefully someone else will be able to chime in with some help; there's not really anything else I can do.

[ftestuz]

It is not about the iCloud sync. iCloud Drive is not activated on my MB.
With OS X Server, you can have network account. On the client machine, you can make those account "mobile" so you can access them even without access to the server.
When the client has access to the server, it synchronizes. This sync is launch automatically or manually.

It's when the document is modified on the client machine that there is an error on sync.

Ah, I was unaware of this setup having any special handling. Are you able to make a sample app I can look at that reproduces the issue?

[ftestuz]

I made a sample app with the problem on my macs. I send it to you ? How ? (Sorry if it's obvious)

[mikeabdullah]

Ah, good point. Can you make a Github Gist perhaps?

I think I did right :
