Problems adding tab to tabpanel

[xxjt123xx]

Class diagram for my viewport


I have created a nice layout in EXT .net but I am having problems trying to add more than one tab.


Inside my formtree menu i have a direct event that calls this method

void editFormClick_Event(object sender, DirectEventArgs e)
        {
            string nodeID = e.ExtraParams["ids"];

            if (nodeID.Contains("|"))
            {
                Guid id = Guid.Parse(nodeID.Split(char.Parse("|"))[1]);
                FormTab tb = new FormTab(id);

                tb.BindData();

                tb.Render(this.MainFormTabPanel);

                if (this.MainFormTabPanel.Items.Where(f => ClientID == tb.ClientID).Count() == 0)
                {
                    tb.AddTo(this.MainFormTabPanel);
                    this.MainFormTabPanel.SetActiveTab(tb.ClientID);
                }
            }
        }

I have no javascript to support adding the tab. I don't know if that is needed.

First edit click


2nd edit click showing 2nd tab


2nd edit click showing 1st tab


In my FormTab Class i am using linq to set the data controls
