Someone will correct me if I'm wrong, but I think localInstanceIn is working only on an existing object in the datastore.
That means that if you create bar into ec2 and you try to do setBarRelationship(bar.localInstanceIn(ec1)) you will get a NullPointerException which could be difficult to track and debug if it happens in the eo class.

So I would recommend to not do it as a cross editingContext exception is "easier" to debug:)

Hi Chuck,

It is always safe to call localInstance.  My personal preference is to force the caller to do that so that they are aware if they have cross EC references.

Ah OK.

I can also see the argument for “just do what is safest”.

I hadn't thought of that benefit to leaving responsibility with the caller.  Anyway, I should pick one as I'm currently doing a bit of each with no consistency.
