php - Symfony workflow::can 通过 workflow guard 事件监听器

Question

如果你们中的很多人已经测试过 symfony workflow 组件，我现在不知道，但我希望你们中的一些人已经测试过 :)

所以，我在两个对象上使用这个组件，我希望第一个对象更新第二个 strong> 取决于它应用的 transition。

为此，我在我的第一个对象上使用了workflow guard listener，并尝试在我的对象上执行一个workflow::apply 第二个对象(使用第二个工作流程...)。

问题是，当我创建一个workflow::can 时，事件被调度 并尝试应用 一个新的状态在我的第二个对象上...这很不正常，因为我只是在问我是否可以应用一些过渡并且不要求实际应用我的第一个对象。

我想我遇到了和你一样的问题，我已经记录了 Symfony 项目的错误:https://github.com/symfony/symfony/issues/33105
