Workflow Activiti-信号和呼叫活动

以下是我们的Activiti（5.21版）主图表： 代码：

代码：



问题是变量“VARIABLE1”和“VARIABLE2”没有传递到“调用活动2”，我想边界信号可能有问题吧？因为他们被传递到“呼叫活动1”。有什么想法吗？
你怎么知道变量没有被发送到调用活动2？
您是否在进程启动时注入变量

我这样问是因为如果在调用Activity 1之前没有初始化流程变量，那么它们实际上不会作为变量传递到子流程中，而是在调用Activity 1子流程的实例化时初始化

因此，如果变量在调用活动1的条目上不存在，那么就没有变量可以传递到调用活动2中

这应该是一个相对容易创建的单元测试，以演示如何解决场景中的任何问题

谢谢

我正在启动时初始化变量。这些变量保存在“调用活动1”的act_ru_变量中。但是，在发出信号之后，当“调用活动2”尝试使用它们时，我得到了一个错误，因为它们没有通过。您可以附加一个单元测试吗。请注意，如果在发送信号之前在被调用的活动1中更新了变量，则更新的值在被调用的活动2中将不可用，因为被调用的子进程存在于其自身的执行上下文中。但是，通过nit测试，我们应该能够看到发生了什么。我实现了一个客户机（使用jdbc的简单java应用程序），目标是进行单元测试，它成功了。所以可能是我们的主要项目。谢谢
