Hi,
The customer has the same database, the same application (same build and stuff like that)
and same everything. This is what freaks me out ;-) Of course something must be different...
I compared the schema several times and they are the same.
Turning on Trace is quite impossible on a production machine. I would rather do a DB migration
and use the primary key "oid" as foreign key constraint instead of some random string field.
Perhaps i can get my hands on another machine which is not production and also results in
that error. Then i could do remote debugging. But even with remote debugging turned on, its
not likely that i fully understand whats wrong.
