    <p>Hi guys maybe I write this the wrong way but can't make it work.</p> <p>I got the following Entity Model: [Division]&lt;0..1>--&lt;*>[Session]&lt;1>--&lt;0..1>[Film]</p> <p>I run the following LINQ query (in LINQPad):</p> <pre><code>from d in Divisions select new {d, d.Sessions, films = from s in d.Sessions where s.Film.Title !=null select s} </code></pre> <p>but I get the error:</p> <blockquote> <p>Constructing or initializing instances of the type &lt;>f__AnonymousType0<code>3[LINQPad.User.Division,System.Collections.ObjectModel.Collection</code>1[LINQPad.User.Session],System.Collections.Generic.IEnumerable`1[LINQPad.User.Session]] with the expression d.Sessions.Where(s => (s.Film.Title != null)) is not supported.</p> </blockquote> <p>I wonder if there is a limitation on applying a filter on 3rd level in WCF Data services or it's a misconception on my side.</p>

Guidance
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).
