Hello,
I have a problem when I try to add a custom tree node in developer section.
I'm using umbraco v4.11.06 and I created a custom project to add a custom tree in developer section.
When I refresh the page, I don't see my custom tree.

In trees.config this is the line for my Custom Tree Node (It seems OK):
<!-- Custom -->
<add silent="false" initialize="true" sortOrder="7" alias="myAlias" application="developer" title="My Custom Tree" iconClosed=".sprTreeFolder" iconOpen=".sprTreeFolder_o" assembly="myCustomTree" type="loadMyCustomTree" action="" />

What's wrong? Any idea? Thank you in advance.

This is my class code.

using System.Text;
using umbraco.businesslogic;
using umbraco.cms.presentation.Trees;

namespace MyAliasAppTree
{
    [Tree("developer", "myAlias", "My Custom Tree", ".sprTreeFolder", ".sprTreeFolder_o", "", false, true, 7)]
    public class loadMyAlias : BaseTree
    {
        public loadClientTools(string application) : base(application)
        { }

        protected override void CreateRootNode(ref XmlTreeNode rootNode)
        {
            rootNode.Icon = FolderIcon;
            rootNode.OpenIcon = FolderIconOpen;
            rootNode.NodeType = "init" + TreeAlias;
            rootNode.NodeID = "init";
        }

        public override void Render(ref XmlTree tree)
        {
            var mct = XmlTreeNode.Create(this);
            mct.Text = "My Custom Tree";
            mct.Icon = "images/myCustomTree.gif";
            mct.Action = "javascript:openMyCustomTree()";
            // Add the node to the tree
            tree.Add(mct);
        }

        public override void RenderJS(ref StringBuilder Javascript)
        {
            Javascript.Append(@"
               function openMyCustomTree() 
               {
                   parent.right.document.location.href = 'plugins/MyCustomProject/myPage.aspx';
               }
           ");
        }
    } 
}
