Roger Shi commented on KYLIN-2514:
----------------------------------
Yes. It's expected and is the correct way to organize the join tables. But in
the case that user delete one join table in the middle and add a new one in the
tail, it usually fails even all the join tables can build a complete join tree.
It would be easier for user if backend can accept and reorder the join tables
once they can be organized as a join tree.
> Joins in data model fail to save when they disorder
