Oh ... I hadn't thought of that.  Thanks.

My understanding of strong and weak references is foggy. Would you mind explaining what each one means? How can you tell when a reference is strong or weak? (I didn't see anything along these lines in Practical WO, but if it's in there, just refer me to where.)

I also found a better description under Legacy Technologies, at Apple:
http://developer.apple.com/documentation/LegacyTechnologies/WebObjects/ WebObjects_5/Topics/ProgrammingTopics.15.html
This gives me the understanding I need to do it. I should have looked a little harder before asking.


Being a former IT technical writer, I don't know why they upgrade the documentation by making it less informative and less useful.

Probably nothing. The EC does not maintain strong references to the EOs registered in it. It only maintains strong references to the inserted/updated/deleted objects that are not yet saved. Just call ec.revert() and you will have no strong references.

Yes, I've read the documentation, but my understanding of the depths of WO is limited. How complicated is it to use a different editing context for a display group? I would like to dispose() the EC when I'm done with it, so I'm not keeping all those EOs around unnecessarily. What do I need to do?

Thank you,
Nathan
