流程回退报错

不要香菜

流程回退报错，下面是错误详细信息，这个方法是bex5的，没有做过更改。
查找之前的帖子http://bbs.wex5.com/forum.php?mo ... rguments&page=2，
确认一下/BIZ/system/logic/action/processExternal.action.m中externalBackProcessQueryAction这个action的参数
/BIZ/system/logic/action/processExternal.procedure.m中externalBackProcessQueryProcedure这个Procedure的参数
/BIZ/system/logic/code/dsrc/ExternalProcessProcedure.java中backProcessQuery的参数
参数也都是一样的，不知道哪里出问题了。

所有的流程回退都报错？

解决了。
报错是因为，之前在onAfterBack事件中写过代码。
后来直接在设计页面删除了onAfterBack事件，但是源码中仍有listener，不知道为什么没有同步删除。
把源码中的listener删除掉就好了。
