@Henrik: Thank you for the valuable input.
@Christoph: As Henrik mentioned, the information provided by the GetDeletes() method is correct, since there was only a in memory operation involved in your case. But the result from the GetInserts() method is not correct and is a bug, which I would like to thank you for pointing out. Please find your Telerik points updated for this.
To your question regarding your tracking system. You can use our ITracking Interface to get notified if an object is modified. With this you can build your own logic to meet your requirements.
I hope this information is helpful for you. Feel free to ask if you have any other question.
All the best,
the Telerik team
