NO SUMMARY

Hmmm, I've never tested Date iCal with FREEBUSY elements before, so that's probably the issue. But since you provided the iCal feed, I can easily do some testing to see if this is a bug.

However, I'll also need a screenshot of your feed importer's Node Processor Mapping page. It's possible that you've misconfigured it.

I found the problem. The iCal spec for VFREEBUSY components doesn't actually allow them to have SUMMARY properties. That is what's preventing iCalcreator, the library that Date iCal uses to parse iCal feeds, from seeing your SUMMARY fields.

I'm currently writing up a patch to Date iCal that will make it possible to import VFREEBUSY components. But the only real way to do it is to make it fall back on the COMMENT property when it can't find SUMMARY. So you'll need to convince google calendar to include a COMMENT in each VFREEBUSY.

If you can't, I'm afraid Date iCal won't work for you. Because this is a limitation in the iCalcreator library, combined with google generating out-of-spec VFREEBUSY components, Date iCal can't really do anything besides trying to hack around it by using COMMENT.

Alright, if you update to the newest Date iCal dev build, you'll be able to import VFREEBUSY components which have a COMMENT property.

To ignore all VFREEBUSY components in the iCal feeds you import, implement this hook in a custom module:

function MODULENAME_date_ical_import_vcalendar_alter(&$calendar, $context) {
  while ($calendar->deleteComponent('vfreebusy')) {
    continue;
  }
}

Replace MODULENAME with the name of the module in which you are implementing this hook. That will delete all the VFREEBUSY components from the calendar before it gets sent through the import process.

Marking fixed. Please reopen if the solution didn't work for you.
