I wanna make sure I understand this correctly. You were originally using the session().defaultEditingContext() to fetch data for your RSS feed. I am assuming you are accessing the RSS feed from a direct action, so when accessing session() you are getting an unneeded session for each request.

You then decided to use the defaultSharedEditingContext in place of the session().defaultEditingContext() to prevent the creation of a new session.

If this is accurate them my first question would be: Why did you not create a new instance of EOEditingContext and use that instead of session().defaultEditingContext()? This will prevent creating a new session for each request and will not have the issues related to the shared editing context.

You should also examine the documentation on "Fetching Data > Ensuring Fresh Data" in this document:

http://developer.apple.com/documentation/WebObjects/Enterprise_Objects/index.html

Example:

public WOActionResults myRSSFeedAction() {

EOEditingContext ec = new EOEditingContext();

ec.lock();

/* Fetch your data and generate RSS feed here */

ec.unlock();

}

Hi guys,
I've been trying to optimize my application a little as I had some RSS feed which was actually creating a session and finally as RSS readers update themselves every x minutes, I just couldn't softly restart the instance.
So I moved the RSS component using the defaultSharedEditingContext, making sure no session was created. So this part was ok so far.
But trying it I saw that the data from the defaultSharedEditingContext didn't update...
I can afford some delay for the update like minutes, but it's been 5 hours now:(

How should I make the sharedEC to update itself? The data are being edited/added using another WOApplication, so maybe the other application could "call" the sharedEC to make it refresh...

Or do:
setRefreshesRefetchedObjects(true);
on the fetch specification should work?

Thanks a lot for any tip:)

Xavier
