bug in panel ghost function

[leeby]

The bug is in ext-4.1RC.

See below red font part, which cause exceptions. The ghostPanel is default as a container, so it doesn't have addTool, setTitle and setIconCls function, also it doesn't even have header element.

// private - used for dragging
ghost: function(cls) {
var me = this,
ghostPanel = me.ghostPanel,
box = me.getBox(),
header;


if (!ghostPanel) {
ghostPanel = new Ext.container.Container({
renderTo: document.body,
floating: {
shadow: false
},
frame: (Ext.supports.CSS3BorderRadius && !me.isWindow) ? me.frame : false,
overlapHeader: me.overlapHeader,
headerPosition: me.headerPosition,
baseCls: me.baseCls,
cls: me.baseCls + '-ghost ' + (cls ||'')
});
me.ghostPanel = ghostPanel;
}
ghostPanel.floatParent = me.floatParent;
if (me.floating) {
ghostPanel.setZIndex(Ext.Number.from(me.el.getStyle('zIndex'), 0));
} else {
ghostPanel.toFront();
}
if (!(me.preventHeader || (me.header === false))) {
header = ghostPanel.header;
// restore options
if (header) {
header.suspendLayouts();
Ext.Array.forEach(header.query('tool'), header.remove, header);
header.resumeLayouts();
}
ghostPanel.addTool(me.ghostTools());
ghostPanel.setTitle(me.title);
ghostPanel.setIconCls(me.iconCls);
}


ghostPanel.el.show();
ghostPanel.setPagePosition(box.x, box.y);
ghostPanel.setSize(box.width, box.height);
me.el.hide();
return ghostPanel;
},

Not sure where you're getting that code from, however in RC1 the code reads:

    ghost: function(cls) {
        var me = this,
            ghostPanel = me.ghostPanel,
            box = me.getBox(),
            header;

        if (!ghostPanel) {
            ghostPanel = new Ext.panel.Panel({
                renderTo: document.body,
                floating: {
                    shadow: false
                },
                frame: (Ext.supports.CSS3BorderRadius && !me.isWindow) ? me.frame : false,
                overlapHeader: me.overlapHeader,
                headerPosition: me.headerPosition,
                baseCls: me.baseCls,
                cls: me.baseCls + '-ghost ' + (cls ||'')
            });
            me.ghostPanel = ghostPanel;
        }
        // .....
    }
