Hi everybody
I’m getting the next exception
Mar 10 16:04:27 Compliance[5000] DEBUG
er.transaction.adaptor.Exceptions - Database Exception occured:
java.lang.IllegalStateException: Cannot obtain globalId for an
object which is registered in an other than the databaseContext's
active editingContext, object: <com.qoslabs.tm.wo.eo.EOTopic

After it happens, it appears more times and my application got dead-
locks and start increasing the number of worker threads.
I’m working with a Web Service in WO 5.4 using Wonder 4.0.0.484. I’m
using a test client to send many request to the Web Service, I could
work fine using 4 clients (2,000 transaction each client) at time.
But when I increased the number of clients (generally 8, but I test
with 5 once) I get the exception randomly (sometimes I could process
more than 6,000 transactions and other times only 50-70
transactions). Every request creates its own transaction and its own
peer editing context. Many transactions build relationships with
common EO’s used as types for others.
What do you mean by "common EO's"? How are the relationships built?
Looking the trace, I notice that the EC [EMAIL PROTECTED] at
WorkerThread11 is saving its changes, it posts a notification to
update others EC and it reaches the other EC [EMAIL PROTECTED] Here a
common EO should to be updated, because its to-many relationship was
modified by first EC (removing an EO in this case, but happens when
adds too) but the common EO was a fault in second EC and it tries to
read it getting the exception because the first EC it’s the active
EC in Database Context. The second EC was created by another thread
(WorkerThread15) but notification was process by same thread
(WorkerThread11) that creates and saves first EC.
I know and I read about this exception in mailing list, a common
mistake is to relate two EO’s in different EC’s. I check my code and
I only use addObjectToBothSidesOfRelationshipWithKey method to do
relationships (even I comment all the methods in my EO’s to set,
addTo or removeFrom relationships), and I extend from Wonder class
ERXGenericRecord, it overrides the method
addObjectToBothSidesOfRelationshipWithKey and it verifies that
this.editingContext() == eo.editingContext(). So I don’t think this
should be the reason.
If you set to-one relationships with setFoo(EOEnterpriseObject) or set
to-many with setFoos(NSArray), it will not call
addObjectToBothSidesOfRelationshipWithKey(). I did not check to see
if ERXGenericRecord checks all the cases.
That exception ONLY happens when this.editingContext() !=
eo.editingContext(). So, somehow, this is happening.
I could say that increasing concurrency I got the exception, but I
don’t know why. And it happens too with WO 5.3.3.
Is there another reason for the exception?
Someone has any idea to follow?
Anyone can help me?
I would suspect that either you have a bug in your code or your app is
running out of memory. It might be an EOF bug, but I think there are
too many other things to look at before deciding that.
Also what does com.qoslabs.tm.wo.MyEC do?
