I updated your thread on Ask with the work around and will notify you there as soon as we get a new presto shipped out.

hmm, i don't doubt what you're saying.. maybe i'm just confused here. i thought this is a heterogeneous tuple (from the schema in the forum post above):
{:db/ident :person/parents
:db/valueType :db.type/tuple
:db/tupleTypes [:db.type/ref :db.type/ref]
:db/cardinality :db.cardinality/one}
which allows refs, and works with transactions and pulls. are you saying that hetero tuples shouldn't contain refs, rather than cannot contain refs?
