Isn't AppUser a subclass of BaseUser too? Where is the qualifier
for that?
That was only my example. EventsUser is the actual class in that case
and for this application (I have also a MeetingsUser in a different
app, same problem there).
...
10:11:00 -- ERXNSLogLog4jBridge -- :46 DEBUG - 4 row(s) processed
But it crashes when interpreting the results:
10:11:00 -- ERXDatabaseContextDelegate -- :153 INFO - Database
Exception occured: java.lang.IllegalStateException:
initializeObject: No snapshot for gid
_EOIntegralKeyGlobalID[EventsUser (java.lang.Long)10049]
Is the row with PK 10049 and EventsUser?
events=# select inheritance_type, contact_id from contacts where
contact_id = 10049; inheritance_type | contact_id
------------------+------------
EventsUser | 10049
Looks good.
On a reduced test case I can't reproduce the problem. I'm at a loss
at the moment. Any ideas where I can look?
.Net? :-P
It sounds like the snapshots are not getting created correctly.
Other than that, no. I fear you are in for some hard work.
Seems so. That's what I'm guessing too, but I have no idea right now
where to start looking. Probably I'll find something eventually, but
if someone has a hint where I could start, that might save me some time.
