I am using the manager classes (modified slightly by me) and have the following code

                ISortExpression sorterActuals = new SortExpression(SortClauseFactory.Create(CubeDealItemUserFieldIndex.CubeDate, SortOperator.Ascending));
                EntityCollection myActuals = CubeDealItemUserManager.MGRGetLoadedActuals(null,sorterActuals);
                
                foreach(CubeDealItemUserEntity myActual in myActuals)
                {
                    myActual.CubeDate.AddMonths(monthsToAdd);
                    myActual.CubeMonth.AddMonths(monthsToAdd);  
                }
                CubeDealItemUserManager.SaveCollection(myActuals);

This code does not update all records in the collection as expected....However if I step through each entity updating individually then that is inefficient with respect to hits to the database.

What am I doing wrong?

What is the quickest and most efficient way to update 1 or more fields in my entity collection?

Many thanks in advance

OK dont answer that I see the problem!!

For future reference, what was the problem, so others might avoid the problem as well?
