(BUG?) Migrating updatable views trouble

Question

I have some simple updatable views created as:
select *
from table
where primary_key in (select ...)
which are working well on database Release1 (10.1.0.3.0 - Linux).
After moving application to Release2 (10.2 - Microsoft Windows, 32-Bit) all these views are no longer updateable.
