it's not a "feature" per-se but DAL has suffered a complete overhaul to
accomodate for new features and some bug squashing.
What used to be a "commodity" leading to "faulty" data models indeed put
the developers (me and Michele Comitini) to face a really hard problem to
solve to support those kinds of tunrarounds.
Let's say its a bug but - at least - let me clearly state that referencing
a table that doesn't exist yet is not a "normal thing to do" :D
