    <p>I'm working on a recursive method that displays all documents I have permissions to see. The first pass works great, but when it calls itself recursively passing a document array of the current document's children it throws an error:</p> <blockquote> <p>Object reference not set to an instance of an object. Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code. </p> <p>Exception Details: System.NullReferenceException: Object reference not set to an instance of an object.</p> </blockquote> <p>Here's the code:</p> <pre><code>protected void Page_Load(object sender, EventArgs e) { lblTest.Text = "Data&lt;br /&gt;&lt;br /&gt;"; Document[] releaseDocs = Document.GetRootDocuments(); displayDocs(releaseDocs); } public void displayDocs(Document[] releaseDocs) { string docPermissions = null; User currentUser = User.GetCurrent(); foreach (var doc in releaseDocs) { docPermissions = currentUser.GetPermissions(doc.Path); if ((docPermissions.Contains("F")) &amp;&amp; (docPermissions.Contains("U"))) { lblTest.Text += "D/T: " + doc.CreateDateTime + "&lt;br /&gt;\r\n"; lblTest.Text += "Level: " + doc.Level + "&lt;br /&gt;\r\n"; lblTest.Text += "Text: " + doc.Text + "&lt;br /&gt;\r\n"; lblTest.Text += "&lt;hr /&gt;\r\n"; if (doc.HasChildren) { Document[] childDocs = Document.GetChildrenForTree(doc.Id); displayDocs(childDocs); //error occurs here } } } } </code></pre>

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.
