Thanks for all the replies,

Indeed, ec.deleteObject(eo) works on a new EO, but... make sure nothing references it, that's where we went wrong.

If you don't explicitly remove the EO from all the relationships you have added it to, it is still saved to the database. And it seems that the only reliable way to remove the object from relationships is by using the removeObjectFromBothSidesOfRelationshipWithKey(...) function.

Hi,
How does one correctly remove/forget/discard/kill/obliterate a new, uncommitted EO from an editing context? The EOEditingContext methods seem to be designed for EOs that have already been committed to the database.

I have never been able to find the correct way to do this without resorting to a combination of calls to EC forgetObject(...) and deleteObject(...), removal of any references through relationships, etc... and every now and then end up creating the EO with nulled relationships anyway in the database when saving the ec.
It all seems like a bit of black magic to me.
