Jira issue originally created by user jackvangalen:
The (deep)copy function of the entity manager is not yet implemented. I assume this is known, but I could not find any open issue on it. This is a pretty powerfull feature once implemented. The function body is completely empty however. Perhaps the tried code could be added so I and others could try and resolve the known issue with this function (recursion limit reached).
Comment created by @beberlei:
There was never code written for that function. I don't think its too problematic that this is missing. You only have to implement **clone (and do so safely as the docs/cookbook describes) and then pass this structure to persist. Optionally making use of cascade persist.
Comment created by mstoehr:
I recently came accross this. Is there any best practice if you have to clone an entity who has several associations? I thought of grabbing them and clone them one by one. Or is there a more convenient way?
no, except implementing **clone and doing it there.
@Ocramius Btw what we discussed on SymfonyCon might actually be removing merge and implementing copy instead.
