Ext.List in Bottom Position in A NavigationView

Hi,

I want to put a List at the bottom of a NavigationView, but its seems not work.

The structure of my screen is like that :

A container set to vbox layout

A Panel set docked to bottom

My List

At first, the List View is not visible, but after adding "height: 100%", the list appears but at the top of my panel.

How could I resolve it?

Thank in advance
