可以正常流转，回退时报错wrong number of arguments

meteor009 · 发表于 2016-3-29 12:38:18

新建的流程中，流转可以正常进行，数据保存正常。点击回退后就报错wrong number of arguments。
我的流程没有调用任何自己写的action,全都是系统自动生成的那几个。请问这个问题怎么解决？

java.lang.IllegalArgumentException: wrong number of arguments是action的参数不正确，控制台的错误信息发完整了吗？只有上面那些错误吗？

externalBackProcessQueryAction 这个action是系统自带的，我也没改过

jishuang · 发表于 2016-3-29 17:31:04

回退是在第一个环节上点的吧？第一个环节前面就没有环节了，不能点回退

meteor009 · 发表于 2016-3-30 09:15:55

不是第一个环节，这个已经是第三个环节，我这个是单线流程，没有分支，任何一个环节回退都报错

meteor009 · 发表于 2016-4-1 09:01:30

什么情况啊？这个问题无法解决吗？

jishuang · 发表于 2016-4-1 11:02:21

把流程现在的波特图发一下看看，从待办任务中打开功能
在导航条的“更多——流程图——波特图”

错误信息就是没有找到可回退的环节
