I wantto remove an entity which is removed to RemovedEntitiesTracker of an EntityCollection.

I tried following code, howeer it throws exception: "[i]Object reference not set to an instance of an object.[/i]"

long pkValdel2 = Convert.ToInt64(entry.Value);

 List<int> x = MakbuzHizmetCollection.RemovedEntitiesTracker.FindMatches(MakbuzHizmetFields.HizmetId == pkValdel2);

 if (x.Count > 0)
 MakbuzHizmetCollection.RemovedEntitiesTracker.RemoveAt(x[0]);
                        

How can i handle that? Thanks...

Does x[0] actually contain a value ?
