如何从rowediting插件的"allowBlank: false“配置中删除窗口错误消息

Ext.create('Ext.grid.Panel', {
    // grid配置...

    plugins: {
        ptype: 'rowediting',
        clicksToEdit: 1,
        autoCancel: false,
        listeners: {
            canceledit: function(editor, context, eOpts) {
                var form = editor.editor.down('form');
                var fields = form.getForm().getFields();

                fields.each(function(field) {
                    field.clearInvalid();
                });
            },
            edit: function(editor, context, eOpts) {
                // 编辑保存逻辑...
            }
        }
    },

    // 其他配置...
});
