    <p>Ok after several attempts I am stuck on this one!</p> <p>I am using NHibernate with QueryOver as below. I have a Product and ProductReview as</p> <pre><code>public class Product { .... public virtual IList&lt;ProductReview&gt; CustomerReviews {get;set;} .... } public class ProductReview { .... public virtual Product Product {get;set;} .... } </code></pre> <p>Mapping on Product side is </p> <pre><code>HasMany(x =&gt; x.CustomerReviews).KeyColumn("ProductId").Inverse().Cascade.None().LazyLoad(); </code></pre> <p>The Query is</p> <pre><code> Product px = null; ProductReview rev = null; var result = CurrentSession .QueryOver&lt;ProductReview&gt;() .Where(r =&gt; r.IsActive &amp;&amp; !r.IsDraft) .Select( Projections.Property&lt;ProductReview&gt;(r =&gt; r.Id).WithAlias(() =&gt; rev.Id), Projections.Property&lt;ProductReview&gt;(r =&gt; r.Title).WithAlias(() =&gt; rev.Title) ) .OrderBy(r =&gt; r.ReviewDate).Desc() .TransformUsing(Transformers.AliasToBean&lt;ProductReview&gt;()) .JoinAlias(r =&gt; r.Product, () =&gt; px) .Select( Projections.Property(() =&gt; px.UPC).WithAlias(() =&gt; px.UPC), Projections.Property(() =&gt; px.FullName).WithAlias(() =&gt; px.FullName) ) .TransformUsing(Transformers.AliasToBean&lt;Product&gt;()) .Take(5) .List(); </code></pre> <p>The error is: The value "Reviews.Models.Product" is not of type "Reviews.Models.ProductReview" and cannot be used in this generic collection. Parameter name: value</p> <p>I really do not want to create another DTO. I would like to get the list of Last 5 new reviews and have it's Product populated (only a few required fields on both entities should be filled).</p> <p>Is this possible by any means (except raw sql) in NHibernate 3.0?</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.
