4. 操作步骤 请简单描述一下复现的操作步骤...

经测试，内嵌模式会把数据域中picker对应的name的变量的变量值清空，把变量值备份等待picker初始化完成后再延迟赋值可以解决此问题，但是延迟多长时间不好确定。 onEvent: { stepChange: { actions: [ { actionType: 'custom', script: 'console.log(context);if(event.data.step==2 && context.props.data.items){var itemsBak = context.props.data.items; setTimeout(function(){console.log("itemsBak=",itemsBak);doAction({"actionType": "setValue","componentId": "wizard", args: {"value": {"items":itemsBak}}});},itemsBak.length*100>1000?itemsBak.length*100:1000);};', }, ], }, },
