I'm saving a list of entities which are unchanged (I have a situation where I'm unsure if they made changes so I just do a save anyway).  The IdeaBlade.EntityModel.EntitySaveOperation object that is returned in the callback has a SaveStaus of "Not OK - Cancelled".  I think previously I've had a status of "NoOperation" when nothing was required to save.  Is this a bug?

Hi hueha,
 
I can't reproduce the issue here. (my SaveStatus is NoOperation)
 
Please provide a small solution against NorthwindIB reproducing the issue.
 
Silvio.

It would probably be worth looking at the debuglog and seeing what that shows, it may give more information.

Also, if you're getting a Not OK, are you seeing any exception in the result args?

No exception 
No error

Looks like something is automatically cancelling the query.

Sorry haven't got time to do a demo yet.  I think the problem is this
1. Copy items into a another entity manager.  
2. Call savechangesasync on the items without changing anything.

Which overload of the SaveChangesAsync are you using?

mgr.SaveChangesAsync(items, null,
                (opResult) =>
                {
                    Repository.ProcessSaveOpResult(opResult, onOK, onCancel);
                }
                , null);

Since I use the same overload in our application I just tried it. Normally you can't save in our app until something is changed but that is easy to circumvent.
 
EntityManager.SaveChangesAsync(EntitiesToImport, null, SaveChangesCallback, null);
 
I attempted to save with a list of 25 entities, none of which had changed. In the SaveChangesCallback my SaveResult was {Ok - No Operation}
 
Sorry, I was unable to reproduce. I tested with 6.0.9.
