Hi Chuck,

No, I'm not using concurrent request dispatching. I'm also not executing a
deleteObject before the saveChanges().

It's not easily reproducible that's for sure, but many of my users are
encountering in after doing just a few or sometimes many many tasks in my
application.

Hi!

I too have see this stacktrace on WO5.2.2 while testing one of our apps with WO5.2.2. I include our stacktrace bellow.

I have only see this exception a few times so it is not easy to reproduce. I don't remember what I did before that saveChanges() when I got this exception.

The ec we use here is a childEC of session.defaultEditingContext and in this application we still havn't implemented locking of this childEC (we are running it under WO5.1.3 in deployment (on solaris) and there we yet havn't seen any problems with this yet).

We _do_ plan to implement locking here! :)

Maybe this is a locking related issue?

Do you use locking on the ec you use when you get this exception?

Here is the stacktrace:

java.lang.NullPointerException at com.webobjects.eocontrol.EOEditingContext._setRecordIsInitialized(EOEditingContext.java:2592) at com.webobjects.eocontrol.EOEditingContext._clearOriginalSnapshotAndInitializeRec(EOEditingContext.java:2584) at com.webobjects.eocontrol.EOEditingContext.didSaveChanges(EOEditingContext.java:3000) at com.webobjects.eocontrol.EOEditingContext.saveChanges(EOEditingContext.java:3156) at NettloggComponent.saveChanges(NettloggComponent.java:209) java.lang.NullPointerException at com.webobjects.eocontrol.EOEditingContext._setRecordIsInitialized(EOEditingContext.java:2592) at com.webobjects.eocontrol.EOEditingContext._clearOriginalSnapshotAndInitializeRec(EOEditingContext.java:2584) at com.webobjects.eocontrol.EOEditingContext.didSaveChanges(EOEditingContext.java:3000) at com.webobjects.eocontrol.EOEditingContext.saveChanges(EOEditingContext.java:3156) at NettloggComponent.saveChanges(NettloggComponent.java:209)
