I have a nested element. When I try to use the "up" method in the painted listener, I get null when querying for formpanel. When I use getParent() to climb the component chain, the formpanel (identified by its auto-generated id) has an xtype value of "element". I'm guessing this is why up is failing.

This was working in 2.0.0.

Code:
 Ext.application({
            launch:function () {
                Ext.create('Ext.form.Panel', {
                    fullscreen:true,
                    items:[
                        {
                            xtype:'fieldset',
                            cls:'notes-form',
                            items:[
                                {
                                    xtype:'textareafield',
                                    name:'notes',
                                    listeners:{
                                        painted:function (c) {
                                            var parentHeight = c.up('formpanel').element.getHeight(true);
                                            c.element.down('textarea').setHeight(parentHeight - 7);
                                        }
                                    }
                                }
                            ]
                        }
                    ]
                });
            }
        });
