Over the weekend I realized that an application I'm working on which uses NHibernate as an ORM to a sqlite database has a concurrency issue. I'm essentially looping through a collection in javascript and executing the following: var item = new Item(); item.id = 1; item.name = 2; $.post("Item/Save", $.toJSON(item), function(data, testSt...
