Hi There,

I'm using the function below to generate a list of nodes from my site. I'm wanting to access the properties of the of the document type in order to use more conditional logic but I'm getting the "Object reference not set to an instance of an object." . I have suspect bit of code marked in bold. Can someone help me fix this code please?

Thanks in advance.

   public void iterateNodes(umbraco.presentation.nodeFactory.Node node)
        {
            if (node.Children.Count > 0)
            {
                var childNodes = node.Children;
                foreach (umbraco.presentation.nodeFactory.Node childNode in childNodes)
                {
                    string strURL = umbraco.library.NiceUrl(childNode.Id);

                    Response.Write(childNode.GetProperty("umbracoNaviHide").Value.ToString());

                    if (childNode.NodeTypeAlias == "HomepageType")
                    {
                        strb.AppendFormat("<li><a href=\"/\">Home</a></li>");
                    }
                    if (childNode.Children.Count > 0 && childNode.NodeTypeAlias != "HomepageType" && childNode.NodeTypeAlias == "SubPageType")
                    {
                            strb.AppendFormat("<li>");
                            strb.AppendFormat("<a href=\"{0}\">{1}</a>", strURL.ToString(), childNode.Name);
                            strb.AppendFormat("<ul>");
                         
                                foreach (umbraco.presentation.nodeFactory.Node j in childNode.Children)
                                {
                                    strb.AppendFormat("<li><a href=\"{0}\">{1}</a></li>", strURL.ToString(), j.Name);
                                }
                         
                            strb.AppendFormat("</ul>");
                            strb.AppendFormat("</li>");
                      
                    }
                    iterateNodes(childNode);
                }


                Literal1.Text = strb.ToString();
            }
        }
