Hello!
I updated my Mac from 10.5 to 10.6 yesterday.
Using the app I developed under 10.5 with a Core Data SQLite store
created under 10.5 I get the following error under 10.6:
"I/O error for database at /Users/norbert/Library/Application Support/
Grosshandel/Grosshandel.grosshandelstore. SQLite error code:1, 'no
such column: t1.Z_75PERSONALACCOUNTS1'"
This error does NOT occur when I create a new Core Data SQLite store
with the same app under 10.6.
I didn NOT edit the store with SQLite directly, of course.
The Entitiy names affected may be "PersonalAccount" and
PersonalAccountRebateGroup" which are related with an optional many-to-
many relationship named "personalAccountRebateGroups" /
"personalAccounts".
Seems to be a problem deeply in Core Data. I have no idea how to
resolve this. I will get a HUGE problem when my existing customers
update from 10.5 to 10.6.
Norbert
