title: How to solve "Batch update returned unexpected row count from update; actual row count: 0; expected: 1" problem?
body: <p>Getting this every time I attempt to CREATE a particular entity ... just want to know how I should go about figuring out the cause.</p>
  <p>I'm using Fluent NHibernate auto-mapping so perhaps I haven't set a convention appropriately and/or need to override somethings in one or more mapping files.  I've gone thru a number of posts on the web regarding this problem and having a hard time figuring out exactly why it is happening in my case.</p>
  <p>The object I'm saving is pretty simple.  It is a &quot;Person&quot; object that references a &quot;Company&quot; entity and has a collection of &quot;Address&quot; entities.  UPDATES work fine on existing Person objects that are already in the database.</p>
  <p>Any suggestions?</p>
