On that topic, In the JCR/alfresco transaction space I found a new place where we need some JCR - alfresco transaction integration. on Session.save() we check for an alfresco transaction which is not present (since a JCR user has no way to open an alfresco transaction).
I know there is a lot of work going on concerning JCR and transactions etc so this may be a mute point.
Changes have been made recently to the Alfresco JCR Session/transaction integration. In order to comply more closely with the specification, it is now possible for a client to use the JCR API without explicit client transaction demarcation. The examples have been updated to reflect this change.
As for opening up a JCR forum, I think that's a good idea. I'll see if we can push that through.
