The journal is constantly watching for the new entries that are created or updated. For every newly created or updated journal entry, it checks whether or not this entry is a bundle (ie, an activity bundle). IF this journal entry is an bundle, it checks if the activity is already installed or not, if not installed, it just installs it. That is basically how the magic activities installation works, IIRC. <div class="gmail_quote">On Tue, Feb 14, 2012 at 7:12 AM, Ajay Garg <<a href="mailto:ajay@activitycentral.com">ajay@activitycentral.com</a>> wrote: <blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">Hi all.
