I have a fullscreen Ext.Panel with card layout.

It contains a nestedlist with cards.

Each card contains a TabPanel.

The TabPanel contains an Ext.form.FormPanel.

Problem is that i can't display the tab content. Nestedlist switch correctly between card but nothings appears under TabBar..


TabPanel generation...
Code:
Ext.define("Lahoco.view.Page", {
    extend : 'Ext.tab.Panel',
    fullscreen: true,
    initialize: function(){
        var tab = 1;
        var panel = Ext.create('Ext.form.FormPanel',{
            title: "Page "+tab,
            items: [
            {
                xtype: 'textfield',
                name : 'name',
                label: 'Name'
            },
            {
                xtype: 'emailfield',
                name : 'email',
                label: 'Email'
            },
            {
                xtype: 'passwordfield',
                name : 'password',
                label: 'Password'
            }
            ]
        });
        
        this.add(panel);
}});
Thx for your help ! ; )
