Symfony workflow ::可以通过工作流程保护事件监听器

Question

如果你们很多人已经测试了symfony workflow组件但我希望你们中的一些人有：）

所以，我在两个对象上使用此组件，我希望第一个对象 更新 第二个 取决于它正在应用的transition。

为此，我使用第一个对象上的workflow guard listener并尝试在我的第二个对象上执行workflow::apply（使用第二个工作流程）。 ..）

问题在于，当我制作workflow::can时，该活动已发送，并尝试在秒中应用新状态对象 ...这是非常不正常的，因为我只是问我是否可以应用某些过渡而不要求实际应用它在我的第一个对象。

我认为我遇到了与您相同的问题，并且我已经在Symfony项目中记录了一个错误：https://github.com/symfony/symfony/issues/33105
