    <p>I have this going me crazy,</p> <p>I'm attaching a List with 1 Customer and 1 Address child record row. Everything seems OK while debugging. 1 customer Row and 1 Address Row should inserted. But instead I get 2 Customer Records and 1 Address Row.</p> <p>I don't know why. When Attaching and looping inside the List only 1 record seen.</p> <p>Any points?</p> <p>[EDITED]</p> <p>Code Attached:</p> <pre><code>public bool InsertUpdateCustomers(List&lt;Customer&gt; customerList, List&lt;Customer&gt; originalCustomers) { using (DbContext db = new DbContext(DbContext.ConnectionString)) { db.Log = Console.Out; List&lt;Customer&gt; customerCloned = new List&lt;Customer&gt;(); customerList.ForEach(p =&gt; customerCloned.Add(p.CloneObjectGraph())); customerCloned.ForEach(p =&gt; p.Address = customerList.Where(pe =&gt; pe.Id == p.Id).Single().Address.CloneObjectGraph()); customerCloned.ForEach(p =&gt; { if (p.Id &gt; 0) { db.Customer.Attach(p, originalCustomers.Single( x =&gt; x.Id == p.Id)); db.Address.Attach(p.Address, originalCustomers.Single( x =&gt; p.AddressId== x.AddressId). Address); } }); customerCloned.ForEach(p =&gt; { if (p.Id == 0) db.Customer.InsertOnSubmit(p); }); try { db.SubmitChanges(ConflictMode.ContinueOnConflict); return true; } catch (Exception ex) { return false; } } } </code></pre> <p>I have checked the Log in the output and I see indeed 2 Inserts in the table. I don't see nothing about the Address, but inserts correctly.</p> <p>It could be the foreign key problem i don't get it.</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
