?

In reply to comment:

Ok so whats wrong with

SomeServiceOrRepository.AddNewRecommendation( newRecommendation )

or

SomeServiceOrRepository.AddNewRecommendation( int parentId, newRecommendation )

Last Sentence? You mean the two questions?

This shouldn't be hard at all.

To summarize my answer I think you are doing things "the hard way" and really should focus on posting form values that correspond to the CRUD action your trying to accomplish.

If a new entity could come in at the same time as your edited entities you should really prefix them differently so the model binder can pick up on it. Even if you have multiple new items you can use the same [0] syntax just prefix the "name" field with New or something.

A lot of times in this scenario you can't rely on Entity Frameworks graph features because removing an entity from a collection never means it should be set for deletion.

If the form is immutable you could also try using the generized attach function off of ObjectSet:

theContect.ObjectSet().Attach( review )

Tons of ways out of this. Maybe you could post your controller and view code?
