I am using NHibernate for a project, and I am absolutely beginner. I am fetching some objects from a table and showing it to a form, where they can be edited. If an user inserts a new object into the table from some other window, I want to show this newly inserted object into the edit window. My application uses tabbed window interface, so user can simultaneously open insert window and edit window at the same time.
So basically what I need is a way to determine if a newly created object exists in the database which is not fetched before by ISession, and if not, then fetch that new object from the database. In other words, I need to synchronize my session with the database, just like flush method, but in the reverse way.
Can anyone help me?
Publish/Subscription method works well for this. Check out the Publishing Events part of Ayende’s sample desktop application. Basically after you’ve added a new item, you publish that information and other parts of your application that subscribed can update their lists accordingly.
