Video on how to install Callisto
Via EclipseZone: Instructional video on how to use the Callisto update site
As the post mentions it shows you in 2 minutes and 35 seconds how to install the entire 140 MB Callisto package. I downloaded Eclipse 3.2 yesterday and installed Callisto using the Callisto Discovery Site and it worked like a charm. Nice. I really like the XML editors that are part of the Callisto distribution - no more paying for XML editing. I'm missing a XSLT editor though... :-(
PMR at Lotus Support
Just got a call from Lotus Support confirming that the issue mentioned previously with mail settings not being correctly applied is indeed a bug in the software. In short the bug implies that a mail setting that requires an agent to be enabled (e.g. the "Allow Notes to update To Do status and dates for incomplete entries" setting on the calendar profile) will not be correctly applied to user mail databases.
For the time being you can use the agent mentioned previously to work around the problem.
