简单流程流转，任务标识不能为空

951234935

问题：任务标识不能为空

流程图：


生产任务书界面：


审批界面：


想要的功能：在第一张图里点击一行，如何执行流程，流程数据源我绑的是另一个相同的数据源，能取到fID，具体怎么传过去？

jishuang

这样的把process组件上的auto-start设置为false
然后自己调用process组件的start( process, name, data, options)方法传fID的值
data这个参数传fID的值

有错误：




这是我的代码:this.comp("process2").start( "/erp/marketSys/process/ProArchives/proArchivesProcess", "项目档案维护", rowID, null);

/erp/marketSys/process/ProArchives/proArchivesProcess是流程的process吗？

在process上右键模型检查看看是否有报错

com.erp.ProcessExecute.doAfterProcessAction(ProcessExecute.java:129)这个是自己的java中，看看java代码中具体到什么地方错的
