Why I can't build my app with sencha cmd?

app.framework.version=4.2.1.883

app.cmd.version=5.0.3.324

Code:

here is my code

Code:

Ext.define('floston.view.editPicker', {
    extend: 'Ext.form.field.Picker',
    alias: 'widget.CustomPicker',
    alternateClassName: ['CustomPicker'],
    triggerCls: Ext.baseCSSPrefix + 'form-time-trigger',
    requires: ['Ext.util.KeyNav'],
    onTriggerClick: function () {
        var me = this;
        if (!me.readOnly && !me.disabled) {
            if (me.isExpanded) {
                me.collapse();
            } else {
                me.expand();
                var oldvalue = Ext.getCmp('idpickerField').getValue();
                Ext.getCmp('idComments').setValue(oldvalue);
         }
            me.inputEl.focus();
        }
    },
    createPicker: function () {
        var me = this,
            picker = new Ext.form.FormPanel({
                pickerField: me,
                floating: true,
                hidden: true,
                ownerCt: this.ownerCt,
                items: [
                    {
                        xtype: 'textarea',
                        id: 'idComments',
                        width: '100%',
                        grow: true
                    },
                    {
                        xtype: 'button',
                        text: 'Submit change',
                        style: {
                            margin: '1.5%',
                            float: 'right'
                        },
                        listeners: {
                            click: function () {
                                var newvalue = Ext.getCmp('idComments').getValue();
                                Ext.getCmp('idpickerField').setValue(newvalue);
                                picker.hide();
                            }
                        }
                    }
                ]
         });
       return picker;
    }
});

Any help will be good.

Thx.
