[EP-tech] Re: undefined value error

Tried excluding all fields_automatic stuff and it still breaks.
I've now tried it against a different (but essentially similar) dev instance and it ran through the whole job without breaking once, which gives me some hope for trying this live.  The simplest solution may be to rebuild this dev instance.  Thanks for the ideas though.

Do you have any automatic processing that's done on commit (typically in eprint_fields_automatic, but could be in other files if you're being clever).

It just seems odd that I've pulled the eprint from the repository, can access the fields, can call set_value on fields and then, on some records only, it loses the eprint object somewhere between the call to 'commit' and the BackCompatibility function...
