nhibernate returning one repeating row

I am using nhibernate with a mysql db. I am trying to do a simple data extraction from one table. I created my entity and my mappings. I am able to talk to the db. It is pulling the correct number of rows from the db table, but each row is a duplicate of the first row in the table. (I have 51 rows in the table. 51 rows are being returned, but each row is a duplicate). I have it set to show sql, and the sql is correct.

Here is a snippet of my mapping file -

<?xml version="1.0" encoding="utf-8" ?>
<hibernate-mapping xmlns="urn:nhibernate-mapping-2.2" assembly="myAssembly" namespace="MyProject.Models.Entities">
  <class name="myClass">
    <id name="id">开发者_如何学Python
      <generator class="identity" />
    </id>

    <property name="column2" />
    <property name="column3" />
....

Does anyone have any idea what might be going on? Thanks for any thoughts.

Is "id" really the id of your entity?

NHibernate will return the same object for all returned rows with that id.
