How to reproduce

Reproducing the problem is also a problem, see this repository

Expected behavior

I'd expect that the UnitOfWork would be able to find an entityIdentifier for OneToOne associations

A little more information and context

I've tried to explain this issue at stackoverflow

I'm not sure if it's L2 cache, it could also be Query Cache. but it has to be some sort of cache, when I disable all cache configuration in the application my Importer commands work perfectly together with all other components. Even the symfony/validation component which is the last component added when the errors started occuring

One other thing, this might be related to this issue or any of the other issues reported with One To One associations and

@maarten-shop4 I believe this should be solved by #7778, would you be able to update to v2.6.4 and try it out?

[nicodemuz]

@lcobucci I just updated to v2.6.4 and I'm also experiencing this issue.

[lcobucci]

@MrNicodemuz interesting, would you be up for sending us a PR with a failing functional test? That should help us a lot to identify and fix the issue.

@lcobucci Here is a stack trace to begin with, not sure if it will be helpful:

The stack is not really helpful, sorry.
