I using a single session to insert/update/delete data.But whenever I am trying to delete a record after insert it ,i get the nhibernate exception

ILLEGAL ATTEMPT TO ASSOCIATE A COLLECTION WITH TWO OPEN SESSIONS.

Although I am using the same session by reconnecting and disconnecting it everytime,I get this exeption while deleting.

Iam not opening and closing the session everytime as i think it will be a burden since the session will have to interact with the database again and again.

Can anybody tell me what is the problem and suggest any solution?

This exception is thrown from PersistentCollection class in the SetCurrentSession method. Following is the code:



If you can post the code that leads to the exception it would be helpful.

This is the base class delete function

protected void Delete(Object itemToDelete)
{

transaction = null;
try
{
if(!session.IsConnected)
session.Reconnect();

transaction = session.BeginTransaction();
session.Delete(itemToDelete);
transaction.Commit();
}
catch
{
transaction.Rollback();
throw;
}
finally
{
session.Disconnect();
}
}
