Hi guys,

I have spent hours and hours trying to get a custom tree to show up in a custom section in umbraco. - With out success.

So far I have managed to create a new section, but when I click that section nothing happens.

What should happen is a custom tree should be displayed with one node. When you click that node It should display an MVC view.

This is what I have done so far, it is based around this tutorial.

http://www.jondjones.com/learn-umbraco-cms/umbraco-developers-guide/customising-umbraco-ui/how-to-display-an-mvc-view-in-the-umbraco-backend

A. Create the section

namespace RewardsMPA.Umbraco.App_Plugins.Rewards
{
    [Application("rewards", "Rewards", "icon-gift", 15)]
    public class RewardsSection: IApplication
    {
    }
}

B. Create the Tree

[Tree("rewards", "rewardsTree", "Rewards")]
[PluginController("Rewards")]
public class RewardsTree : BaseTree
{
    public RewardsTree(string application)
        : base(application)
    { }

    protected override void CreateRootNode(ref XmlTreeNode rootNode)
    {
        rootNode.NodeType = "rewards";
        rootNode.NodeID = "-1";
        rootNode.Menu = new List<IAction> { ActionRefresh.Instance };

    }

    public override void Render(ref XmlTree tree)
    {
        var IndexNode = XmlTreeNode.Create(this);
        IndexNode.NodeID = "0";
        IndexNode.NodeType = "Home";
        IndexNode.Text = "Home";
        IndexNode.Action = "javascript:openPage('/umbraco/backoffice/Plugins/Rewards/Index');";
        IndexNode.Icon = "icon-home";
        IndexNode.HasChildren = false;
        IndexNode.Menu = new List<IAction>();
        OnBeforeNodeRender(ref tree, ref IndexNode, EventArgs.Empty);

        if (IndexNode != null)
        {
            tree.Add(IndexNode);
            OnAfterNodeRender(ref tree, ref IndexNode, EventArgs.Empty);
        }
    }

    public override void RenderJS(ref StringBuilder Javascript)
    {
        var js = $"function openPage(url){{UmbClientMgr.contentFrame(url);}}";
        Javascript.Append(js);
    }

    protected override void CreateAllowedActions(ref List<IAction> actions)
    {
        actions.Clear();
        actions.Add(ActionNew.Instance);
        actions.Add(ActionDelete.Instance);
        actions.Add(ContextMenuSeperator.Instance);
        actions.Add(ActionRefresh.Instance);
    }
}

C. RegisterRoutes (called on ApplicationStarted)

public static void RegisterRoutes(RouteCollection routes)
{
    routes.IgnoreRoute("{resource}.axd/{*pathInfo}");
    routes.MapRoute(
          name: "Default",
          url: "umbraco/backoffice/Plugins/{controller}/{action}/{id}",
          defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional }
      );
}
public class StartUpHandlers : ApplicationEventHandler
{
    protected override void ApplicationStarted(UmbracoApplicationBase umbracoApplication, ApplicationContext applicationContext)
    {
        RouteConfig.RegisterRoutes(RouteTable.Routes);
    }
}

D. Back-end Controller - Returning view I want to see.

public class RewardsController : UmbracoAuthorizedController
{
    public ActionResult Index()
    {
        return View("~/App_Plugins/Rewards/Views/RewardsHome/Index.cshtml");
    }
}

So what am I missing?

I put break points in the RewardsTree Class but none of them are hit.

I also put break points on Application Started and those break points are being hit so I am pretty sure the route is being configured correctly.

Is there anything that I am missing? I have seen other examples using a TreeController insted of TreeBase which has confused me a bit.

ANY ideas? - very stuck
