Yes, I followed

http://doc.silverstripe.com/doku.php?id=recipes:extending_the_event_calendar

but it is the remnant of the days when there was no popup but each field at table was filled separately.

Now problem solved

Thanks a lot. Victor

PS. At this moment I recall issues:
1) Ghost Next Meetings (if I create Repeating Event(1 week) with the last day April 28 then there is no event on May 5,12,19 but they are listed as Future Events ("see other dates") on April 28 and May 5,12 are also listed on April 21, May 5 is listed on April 21)

2) Import of ICS (I noticed you are working)

3) Export of repeating event - I understand the difficulty now;

4) Again repeating event - it would be nice after creating it to have a procedure to breaking it into single events - or to create many single events in one shot: say we are planning seminar each Friday, 14:10 to 15:00, from September X to December Y, each meeting has TBA speaker, .... , Content; those will be clarified in the future and filled differently for each meeting. It cannot be done probably as repeating event because $Content of each meeting is different and it is really $Content, it requires TinyMCE to edit

5) Alignment in blackcandy

I searched the entire directory and couldn't find calendar_toggle.js is the file supposed to be included or do we get it off of somewhere?

Also still having trouble with the Extendend Calendar the announcements tab doesn't add anything to my database. I click add Calendar Date Time. Fill in all the fields, then click save. It then says success! (close popup), but the fields are still blank.. Any ideas?

public function init()   {
   parent::init();
   Requirements::javascript('mysite/javascript/calendar_toggle.js');
}

Xeal, You can steal calendar_toggle.js from

http://eventcalendar.bluehousegroup.com/advanced-calendar/

The calendar_toggle.js is legacy from when the Calendar supported control over event display behavior. It doesn't do that anymore. Where are you finding a reference to this file?

Can you explain what you are doing that is causing the announcements to break?
