我需要将两个物体放在一个带有液体的物体中。 背景是：我有一个userDomain和一个订购对象。两者都不是持久的。我想将这两个对象发送到一个动作而不使其中一个持久化。 userDomain对象由表单处理，另一个对象分配给视图。如果我将排序对象添加到表单中的参数部分，Typo3会抛出这个错误：
Oops, an error occurred!
Could not serialize Domain Object Whmcs\Registration\Domain\Model\Ordering. It is neither an Entity with identity properties set, nor a Value Object.
More information regarding this error might be available online.
这是因为该对象是非持久性的，并且没有任何ID。
所以问题是，我如何将这两个对象传递给下一个动作？
答案 0 :(得分：1)
为了在多个动作之间传递非持久对象，我建议您将序列化的对象存储在TYPO3会话变量中。这样做，您可以恢复目标操作中的对象。
下面是一个工作示例，也可以找到here。
