My scenario: NHibernate v1.0.2.0 | SQL Server 2000 | VB.NET 2005.
My problem:

I am trying to obtain all articles of the table, but it gives the following exception:

"No row with the given identifier exists: 249, of class: Article".

ID 249 don't exist in the articles table and I do not understand because it tries to bring this ID.

From where obtains this ID?

Try different consultations and in all I such obtain results with values that are not either in the table.

My map file:

************************************************************************************************
<class name="Article" table="Articles">

<id name="_id" column="ID" unsaved-value="0" access="field">
<generator class="identity" />

My code:

Public Function GetActiveArticles() As IList

Dim session As ISession = Nothing

Try

session = _nhFactory.OpenSession

Return session.CreateCriteria(GetType(Article)). _
Add(Expression.Expression.Eq("_active", True)). _
AddOrder(Expression.Order.Asc("_name")).List

Catch ex As Exception

Throw New ApplicationException("Could not get articles.", ex)

Finally

If Not session Is Nothing Then _
session.Close()
End Try

End Function


Thank's in advance!!
