Finally i have my tree out of a Many2Many Table using ModelSQL and
overriding table_querry() using WITH RECURSIVE.
For usual data it works fine.
But it doesn't work with a tree were one leaf or knot shows up two times
at 2 different places.
in this Case I get an Error in the Client: "You try to read records that
don't exist anymore."
I located the place were the error is triggered:
model/modelsql.py line 704 there is a check:
"if not len(fetchall) == len({}.fromkeys(sub_ids)):"
If i comment out the whole if clause or just the line calling the error
(line 717) it works fine.
How important is this check? How much do i risk if i leave this
error-call disabeled?
