That comes from Wonder, that message is logged from either ERXEOAccessUtilities
or ERXTolerantSaver. It is trying to process the thrown exception and not
finding some important pieces of data. I don't know why they would be missing.
That is the first thing that I would investigate. You are using the FrontBase
plugin framework, right?
As it is coming from a log4j logger in wonder, you could set the threshold to
FATAL to prevent this logging.

Let me thank you again -- it seems it works great!
One small glitch though: before I get the exception in catch() and can process
it, someone up there (looks like the frontbase JDBC adaptor) logs out heaps and
heaps of things, which start with

and go on for a long long time.
Is there a way to suppress this log? Not only it clutters the log files, but
it's long enough to make the application perceptibly slower.
Thanks a lot,

(b) concurrent inserts
This problem is caused by my using fixed PKs (though if I did not, I might be
getting duplicated EOs instead). If two instances try to insert a new EO with
the same PK, I'm (naturally) getting a constraint PK violation exception from
the database.
And I can't find a way to solve it :(
I can (and do) try to fetch the offending object -- and since the other
instance committed meantime, I get it all right:
===
... code as above ...
if (ocs_is_primary_key_constraint(exception) &&
adaptorOp.adaptorOperator()==EODatabaseOperation.AdaptorInsertOperator) {
NSArray pka=entity.primaryKeyAttributes()
EOQualifier
pkq=ERXEOAccessUtilities.qualifierFromAttributes(pka,adaptorOp.changedValues())
// contains the PK
EOFetchSpecification fs=new EOFetchSpecification(entityName,pkq,null)
fs.setRefreshesRefetchedObjects(YES)
NSArray objs=ec.objectsWithFetchSpecification(fs)
if (objs.count()==1) {
// OK, my code does get here, the object inserted by other instance is
fetched all right. But what now?!?
???
_saveTolerantlyChangesInEC(ec) // let's try again
... ...
===
What to do at the ??? place? If I do nothing, the insert operation stays in EC
and fails again.
I've tried to remove the newly added object from ec.insertedObjects. Strangely
enough it did work (i.e., it has been removed -- self evidently, internally
insertedObjects is a mutable array), but did not help -- this way led to the
dreaded "rowDiffsForAttributes: snapshot in
com.webobjects.eoaccess.EODatabaseOperation {_dbSnapshot = {}; ..." exceptions.
Currently I am recording the PK and entity, and in my
databaseContextWillOrderAdaptorOperations I do not add adaptor operation for
such an insert. This seems to sort of work, but is TERRIBLY convoluted -- there
must be a better solution?
Set the relationships for any other objects into the EC to the one fetched, not
the one just created and then ec.deleteObject(dupicate object))
