not doint the unwrap() but add() directly was a bugfix for one of your other issues .Why is unwrap in here again?

Oops - that was a mistake. I have attached multipleaddmerge2.diff which no longer uses unwrap to add the element.

That is exactly the same code in the patch, the lines are just formatted differently.

Sorry, I am still getting the hang of git and diff and maybe what I put in there isn't what I meant to. I have now pushed the code to the DDC-875 branch on my ccapndave/doctrine2 fork on GitHub, hopefully this works better.

As far as I can tell I am using unwrap() in order to check whether the element already exists in the array, but then calling >add() directly on the PersistentCollection rather than the ArrayCollection, triggering $this>changed().

It seems even this issue is caused by multiple calls to persist. I cannot reproduce this with just a single bidirectional cascade merge.

We cannot reproduce this error and haven't had similar complaints ever-since. Feel free to open a new issue with a failing testcase.
