    <p>I'm having some difficulties mapping the following sitation:</p> <p>I have a person with a connection id, I use this to get map a bag and a property. This works if the database already exists. But for our unit tests, we generate one from the schema, it gives an error : "duplicate column names".</p> <p>Here is the mapping:</p> <pre><code> &lt;?xml version="1.0" encoding="utf-8" ?&gt; &lt;hibernate-mapping xmlns="urn:nhibernate-mapping-2.2" namespace="DomainLayer.SearchDomain" assembly="Test"&gt; &lt;class name="SearchPerson" table="person" lazy="false" mutable="false"&gt; &lt;id name="Id" column="`id`" type="int"&gt; &lt;generator class="identity" /&gt; &lt;/id&gt; &lt;property name="Name" column="`NAAM`" type="string" /&gt; &lt;property name="FirstName" column="`VOORNAAM`" type="string" /&gt; &lt;property name="ConnectionId" column="`Koppelid`" type="int" /&gt; &lt;bag name="Languages" lazy="false" mutable="false" access="field.camelcase-underscore"&gt; &lt;key property-ref="ConnectionId" column="Koppelid" /&gt; &lt;one-to-many class="DomainLayer.Person.LanguageSkill, Test" /&gt; &lt;/bag&gt; &lt;/class&gt; &lt;/hibernate-mapping&gt; </code></pre> <p>Problem: "Koppelid" both in Key property from the bag as in the property. </p> <p><strong>Edit:</strong></p> <p>The LanguageSkill mapping:</p> <pre><code>&lt;?xml version="1.0" encoding="utf-8" ?&gt; &lt;hibernate-mapping xmlns="urn:nhibernate-mapping-2.2" namespace="DomainLayer.Person" assembly="Test"&gt; &lt;class name="LanguageSkill" table="languageskill" lazy="false"&gt; &lt;id name="Id" type="Int32"&gt; &lt;generator class="identity" /&gt; &lt;/id&gt; &lt;property name="ConnectionId" column="`KoppelId`" type="Int64" /&gt; &lt;property name="Remark" column="`Opmerking`" type="string" /&gt; &lt;property name="Source" column="`CdOorsprong`" type="string" /&gt; &lt;property name="MotherTongue" column="`moedertaal`" type="boolean" /&gt; &lt;property name="ModifiedDate" column="`wyzdat`" type="DateTime" /&gt; &lt;/class&gt; &lt;/hibernate-mapping&gt; </code></pre>

    1. COthe key column in the bag effects the other table not table WN so this can't be the problem. post the mapping of LanguageSkill as well because i suspect the error there

    2. COYeah, you're right. The mapping of LanguageSkill contains a property ConnectionId (column name "koppelid"). I've added the language skill mapping in the OP.

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.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
