Hello, I have a problem with show card after close tab. My code is below. When I firstly select item I have a grid in my tabpanel with card on top. But when I close and select item once again I have only grid but card is not visible. Any suggestions? How can I show my active card?
var addTab = function (tabPanel, mygrid) {
    var tab = tabPanel.getComponent(mygrid);
    var mytabbar = tabPanel.getTabBar();
    if (!tab) {
        tab = tabPanel.add(mygrid);



//use after item from tree panel is select
        var mycmp = Ext.getCmp(komponent);
        var T = Ext.getCmp('tablist');
