Here's the info on the dispose() method:
http://developer.apple.com/documentation/WebObjects/Reference/API/com/ webobjects/eocontrol/EOEditingContext.html#dispose()


Currently, the only time I use the dispose method is when I need to access the recent saves immediately, since it unlocks and breaks connections (etc, see the ref). Even within the same application, recently saved objects will not show up unless I do a dispose() first, from the component that made the save. I put it in the methods that call up other components, so I'm sure I won't be needing it for something else on the same page.

The more I think about it, the more I convince myself that this would be a good memory saver. I've read that Java is supposed to do this type of clean-up on its own, but apparently it doesn't get around to doing it for a while. I don't have a while to wait for the information to become available, so I force the garbage collection.

It may disrupt backtracking ... not sure, since I don't use backtracking.

In a different situation, I've had great success by not using this.session().defaultEditingContext()
Instead, create a new editing context, then after saving changes, do
ec.dispose()
(maybe in the functions that go to other pages).

I do something similar but I don't do the ec.dispose(). What does doing the dispose trigger? IOW, should I go back to my code and add disposes?
