标准动作扩展功能实现步骤？

wto.2008

我的操作步骤如下：
1、根据标准动作扩展视频长度在54：44段（有相应的程序代码段）；
2、根据标准动作生成代码；
3、在重新定义的代码段里添加新的业务；
4、在运行时对添加新的业务代码异常；（请协助处理）

如上图对新添加的代码取消就正常，否则提示“新增数据失败！”

没有设置默认值那就是null

案例中的可以用是引用案例中的这个概念是从概念，从data设置的master中默认关联主的id，这个id在新增的时候默认生成就有默认值，而且在data的onNewCreateParam事件中也设置了默认值

参考/UI2/demo/actions/process/standardActionExtend/mainActivity.w中dProjectPlan这个data的事件和属性的设置
