Solved: [Zope3-dev] persistent data in (not local) utilitiy

[Markus Leist]

Ok, getUtility() doesn't work, but:

def bootStrapSubscriberDatabase(event):
[...]
    db, connection, root, root_folder = getInformationFromEvent(event)
    if ( ensureUtility(root_folder, IIkAdminUtility, 'IkAdminUtility', IkAdminUtility, '') ) :
        logger.info("Ensure unnamed IkAdminUtility")
    sm = root_folder.getSiteManager()
    utils = [reg for reg in sm.utilities.registrations()
                 if reg.provided.isOrExtends(IIkAdminUtility)]
    # [0] is a dirty quick hack
    instIkAdminUtility = utils[0].component
    instIkAdminUtility.nbrStarts += 1
    [...]
    transaction.get().commit()
    connection.close()

does.

Bye, Markus
