Upcoming_Events with Merged Calendars

[ttechnology]

Sorry if I missed this elsewhere, but I did not see anything in the forums via search.

I am just getting around to implementing Upcoming_Events. I am using PLANS 7.6.3 and am finding that it displays nothing on calendars that are rolled-up or merged calendars. What am I doing wrong?

Here's my HTML setup:
var ue0 = new plans_upcoming_events({'id':'ue0',
'background_calendars_mode':'list',
'list_element':'upcoming_events_list',
'menu_element':'upcoming_events_menu',
'plans_url':'http:\/\/localhost2/cal/plans.cgi',
'cal_ids':'6,4,1,0',
'merge_days':true,
'include_details':false,
'days_before':'0',
'days_after':'30'});

The dropdown created shows all 4 calendars. Calendar 6 is an events calendar. Calendar 4 is a training calendar. Calendar 0 rolls up the two. 6 shows something. 4 shows something. 0 shows nothing. All work on the regular calendar.

If I change the background_calendar_mode property to 'one_big_list', the only area that calendar access appears to possibly work differently, content appears to work the same.

Ideas? Thanks,

Scott
