    <p>I've created 2 objects:</p> <pre><code>public class Set { public Set() { _sorts = new List&lt;Sort&gt;(); } public virtual int Id { get; set; } public virtual string Code { get; set; } private ICollection&lt;Sort&gt; _sorts; public virtual ICollection&lt;Sort&gt; Sorts { get { return _sorts; } set { _sorts = value; } } } public class Sort { public Sort() { _sets = new List&lt;Set&gt;(); } public virtual int Id { get; set; } public virtual string Name { get; set; } private ICollection&lt;Set&gt; _sets; public virtual ICollection&lt;Set&gt; Sets { get { return _sets; } set { _sets = value; } } } </code></pre> <p>And 2 mappings:</p> <pre><code>public class SetMapping: ClassMapping&lt;Set&gt; { public SetMapping() { Table("Sets"); Id(x =&gt; x.Id, map =&gt; map.Generator(IdGeneratorSelector.CreateGenerator())); Property(x =&gt; x.Code, map =&gt; { map.Length(50); map.NotNullable(false); }); Bag(x =&gt; x.Sorts, map =&gt; { map.Key(k =&gt; { k.Column("SetId"); k.NotNullable(true); }); map.Cascade(Cascade.All); map.Table("SetsToSorts"); map.Inverse(true); }, r =&gt; r.ManyToMany(m =&gt; m.Column("SortId"))); } } public class SortMapping: ClassMapping&lt;Sort&gt; { public SortMapping() { Table("Sorts"); Id(x =&gt; x.Id, map =&gt; map.Generator(IdGeneratorSelector.CreateGenerator())); Property(x =&gt; x.Name, map =&gt; { map.Length(50); map.NotNullable(false); }); } } </code></pre> <p>usage: Set can have many sorts Sort can belong to many sets.</p> <p>And I would like to use this as:</p> <pre><code>var set = new Set() {Code = "001"}; var sort = new Sort {Name = "My name"}; set.Sorts.Add(sort); sort.Sets.Add(set); </code></pre> <p>Somehow the relations are not working yet because when I try to use the above code to add sorts to set for example and commit then I don't see any records saved to the SetsToSorts linked table.</p> <p>Does anyone have a clue what I'm missing in my mapping? Or otherwise doing wrong?</p> <p>Thank you, Joost</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.
