Bonita -如何跳过任务执行

Question

我正在开发一个bonita进程，以便在实例中运行。我需要在每个任务上使用自定义的参与者筛选器，以选择可能的审批者。

每个参与者被映射到一个角色(

• )，每个用户至少有一个角色成员和一个组(
• )，有些用户至少有两个具有相同角色的成员关系和两个不同的组(

)。

基于配置的“我的参与者筛选器”可以匹配属于一个或两个组的用户以及与该参与者关联的角色。

在这里之前一切都很好但是..。

我可能没有这个任务的可用批准者，所以我需要跳过它。一切似乎都好起来了，但我的问题来了：

当我试图跳过任务时，执行失败，因为任务没有输入。

所有任务都有一个带有文本变量inputAction的契约输入，其值为“已批准”或“拒绝”。

我试过了

users;

• return

• 返回一个空的用户is列表，但是实例化失败，因为参与者筛选器不返回用户is的空列表，跳过任务并带有附加“捕捉错误”的任务，但是任务没有跳过(异常above);

• throw a UserFilterException，但任务没有跳过(上面的例外)；

• 使用默认操作，但任务没有跳过(上面的例外)。

有办法做到这一点吗？

Answer 1

这一问题是由于使用了局部变量ti流程审批者的行动。这些变量在失败时尚未创建，因此不可能跳过任务(bug?)。移动到集合变量解决了我的问题。
