php - Symfony工作流::可以通过工作流 guard 事件监听器

我现在不知道是否很多人已经测试了symfony workflow组件，但我希望你们中的一些人有:)

因此，我在两个对象上使用此组件，并且我希望第一个对象到更新，然后将第二个更新到它取决于所应用的transition。

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

问题是，当我制作workflow::can时，该事件是分派(dispatch)的，它试​​图在我的第二个对象上应用一个新的状态...这是很不正常的，因为我只是问我是否可以将应用于某些过渡，而不是，向询问，实际上将应用于我的第一个对象。

我想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
