How to detect that an operation is not succeeded?

[VitalyStakhov]

Hi,

I have both MongoDB and MongoCollection instances instantiated and initialized when the phone had internet connection. Later, when internet connection is gone I try to update a collection via

colleciton.update(...)

How do I check if that update operation is successful? As I can see the update method returns MongoResult, which has isSuccessful, but MongoResult.isSuccessful is always true for me if nothing is updated in the database and the phone didn't even have internet connection
