I have one 'Transaction' entity object with 'Operations' navproperty with multiplicity of 'Many'.

When I'm adding only one operation per transaction nothing happens, but when I'm trying to add more than one operation, db.SaveChanges() throws an exception like 'Subquery returned more than 1 value blah, blah, blah'

How can I solve that? Help me guys please...

BTW... Could you tell me how can I see the exact query string that EF passes to Sql Server on db.SaveChanges() method?
