How to Solve NHibernate entity association issue?

Asked By nadeemrao 0 points N/A Posted on - 08/09/2011

I am having issues with NHibernate. I have got a few methods in DAL and I use Session Factory.

When I run this application it  runs perfectly alright, but there are sometimes it throws in an exception saying Entity <Entity Name> is already associated with entity ID <Number>.

I am looking for ways to solve this issue; any idea?

How to Solve NHibernate entity association issue?

Hi Nadeemrao!

NHibernates have different sessions of which session factory is one of them.

These errors usually occur when you are creating a new entity on every database call and sometimes using old ones.

If you are using Poco entities, the frequency of this issue will be reduced to 10% and get the session object for poco entity in each method.

To resolve the method completely I am suggesting a method that worked for me: I cleared the session on every database call and in this way, everything worked for me.

Although am not sure if it will work for you, you can give it a trial.
