Panel does not expand vertically in a TabPanel

Using Extjs, I've got a TabPanel containing two Panels. Those panels do not automatically expand vertically. All layout are set with type 'fit' and forceFit is true.

Edit:

I've updated my code according the Kunal's suggestion.

To describe the interface: you have a tree list containing several nodes. When the user clicks on one of those nodes it o开发者_开发技巧pens a tab (calling the function ZombieTab(zombie_ip)) with two sub-tabs (ZombieTab_MainTab and ZombieTab_Commands).

Editing the code with Kunal's suggestion had the following effect: We can see that the ZombieTab_Commands's bottom bars appears at the top of the panel and as a result, all components of the tab are not displayed.

Is the main tab of your, which is ZombieTab, is taking the whole space?

If yes, I would make changes for child panels as

ZombieTab_MainTab.superclass.constructor.call(this, {
    id: 'zombie-main-tab',
    layout:'fit',
    title: 'Main',
    items: {
            layout:'border',
            items:[top_bar, logs]
           }
});

similarly for other child panel as well.

For the Toolbar in Command Tab, try replacing with normal Ext Toolbar and see the effect.

    bbar: new Ext.Toolbar({
        id: 'exploits-bbar-zombie-'+zombie_ip,
        text: 'ready',
        border: false,
        iconCls: 'x-status-valid',
        items : [ { text: 'test'} ]
    })
