Cannot obtain globalId for an object in savaChanges

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 pk:"26">, databaseContext: er.extensions.ERXDatabaseContext@1f4e571, object's editingContext: com.qoslabs.tm.wo.MyEC@ae864e, databaseContext's active editingContext: com.qoslabs.tm.wo.MyEC@148e70d

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.

 

Looking the trace, I notice that the EC MyEC@148e70d at WorkerThread11 is saving its changes, it posts a notification to update others EC and it reaches the other EC MyEC@ae864e. 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.

 

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?

 

Regards

Federico
