Question

我有一个父进程，其中子进程以“ callActivity”开始。子进程包含两个任务，task1和task2。当我尝试在“ task1”或“ task2”处启动parentProcess时，出现了NotValidException：

org.camunda.bpm.engine.exception.NotValidException: Element 'task2' does not exist in process parentProcess:1:324: targetElement is null

    at org.camunda.bpm.engine.impl.ProcessInstantiationBuilderImpl.execute(ProcessInstantiationBuilderImpl.java:127)

这是我尝试在“ task2”处启动该过程的方法。

runtimeService.createProcessInstanceByKey("parentProcess")
    .startBeforeActivity("task2")
    .execute()

要稍微了解一下上下文：我们需要将旧流程实例迁移到新定义中，因此我们需要能够从流程中的任何用户任务开始。

我想念什么？

如果我正确地阅读了您的问题，则可能是您试图在仅对（子）子流程定义有效的步骤上启动父流程定义的实例。正确吗？

如果是这样，那么您看到的行为就是预期的行为，您需要在父流程定义中指定一个活动。

在父实例中遇到子流程调用后，您可以利用某些选项在特定步骤启动子流程实例，但是调用活动不支持该选项，因此需要通过Java API调用进行操作，可以在服务任务或脚本任务中完成。

无法在子流程中定义的活动处启动beforeActivity
