I think I have managed to get to the bottom of this. I believe there is a
weakness in the explodeExpression method, which causes this NPE when there
are invalid expressions present in the system. Version 2.10 seemed to be
rather tolerant of this but wit the change to UIDs in expressions, some of
the "invalid" expressions were not being upgraded, which I noticed in the
logs. After the ugprade to 2.12 (from 2.10), there were a large number of
expressions which were invalid.

1) Blank expressions. These very likely were from our original import from
1.4, and have been there all along, but never really been detected.
2) Invalid expressions which were unable to be upgraded.These were all the
ones which did not have UIDs in them .

I was not exactly sure (am still not am) what the implications of removing
these were. In some cases, I got a key violation with expressiondataelement
and I removed these as well. After all of that witchcraft, I started up the
system again, and it worked.

I think the explodeExpression method is expecting valid expressions, but
these were not being picked up in the integrity checks for some reason and
ends up throwing this exception which prevents the download of metadata
during data entry.

Regards,
Jason
