Bonita

Question

我正在 Bonita Enterprise 实例中开发运行的 bonita 流程。我需要在每个任务上使用自定义参与者过滤器，以选择可能的批准者。

每个演员都映射到一个角色
每个用户至少有一个具有角色和组的成员资格
一些用户至少有两个具有相同角色和两个不同组的成员资格

我的演员过滤器基于配置，可以匹配属于一个或两个组的用户以及与演员关联的角色。

到这里为止一切都很好，但是...

我可能没有可用的任务批准人，所以我需要跳过它。一切似乎又好了，但我的问题来了：

当我尝试跳过任务时，执行失败，因为任务没有输入:

所有任务都有一个合同输入，文本变量 inputAction 的值为 "approved" 或 "rejected"。

我试过了

return 一个空的用户 ID 列表，但实例化失败，因为演员过滤器 return 没有用户；
return 一个空的用户 ID 列表并跳过带有附加到任务的 "Catch error" 的任务，但任务不会被跳过（上述异常）；
抛出 UserFilterException，但未跳过任务（上述异常）；
使用默认操作，但不会跳过任务（上述异常）。

有没有办法做到这一点？

Answer 1

该问题是由于使用了局部变量 ti 处理审批者操作。这些变量在失败时尚未创建，因此不可能跳过任务（错误？）。转移到池变量解决了我的问题。
