Hi community

I have made a custom section with a custom tree using the tutorial videos on the umbraco website. This works fantastic (besides I need to click a default section first before my custom section will load) but when I click on my tree the javascript which is needed to load the right panel isn't fireing.. I searched this forum and the internet but I didn't found any posts with this problem. Does anyone know what is giving this problem or how to solve this? Here's my code for your information..

using umbraco.cms.presentation.Trees; using umbraco.BusinessLogic; namespace CostumLogic.Trees.Newsletter { public class loadSubscribers : BaseTree { public loadSubscribers(string app) : base(app) { } protected override void CreateRootNode(ref XmlTreeNode rootNode) { rootNode.Icon = FolderIcon; rootNode.OpenIcon = FolderIconOpen; rootNode.NodeType = TreeAlias; rootNode.NodeID = "init"; } public override void RenderJS(ref System.Text.StringBuilder Javascript) { //best practice is om deze te noemen 'open' + de alias van je custom tree Javascript.Append( @" function openSubscribers() { alert('function is being called!'); parent.right.document.location.href = 'plugins/Newsletter/showNewsletterSubscribers.aspx; } "); } public override void Render(ref XmlTree tree) { XmlTreeNode xNode = XmlTreeNode.Create(this); xNode.NodeID = "1"; xNode.Text = "Subscribers"; xNode.Icon = "subscribers.gif"; xNode.Action = "javascript:openSubscribers()"; tree.Add(xNode); } } }
