warning: date_format() expects parameter 1 to be DateTime .... /fullcalendar.module on line 320 [#1039140]

I get this error when trying to add two fields (or add a multi-date field) in "Row style: Node - FullCalendar" options:

• warning: date_format() expects parameter 1 to be DateTime, null given in /Users/Cale/Sites/acquia-drupal/sites/all/modules/fullcalendar/fullcalendar.module on line 320.

There are a lot of people with this type of error but not with fullcalendar.module at the end.

319  $attributes['index'] = $index;
320  $attributes['start'] = date_format($attributes['start'], DATE_FORMAT_DATETIME);
321  $attributes['end'] = date_format($attributes['end'], DATE_FORMAT_DATETIME);
322
323  return l($text, $node->url, array('attributes' => $attributes));
}

I had a single date event working fine on one view... and a multi-date (From and To) event working fine on another view... but sometimes I get this error at the top of the calendar view... and I certainly cannot see the two events together on one view. I must not be doing something wrong. Thanks for help

Update:

I seem to run into this error message when a field is not inputted yet. Thus, if i created the node but left the field empty. But this error is a little fidgety. Can't quite explain it yet--as it also comes up when I'm using the "From and To" date pop up selection field.

HOWEVER, I cannot get two different date fields operational on the FullCalendar. Even if I have created two separate single-date fields and inputted them correctly...

In My Calendar Row Style Options
Date Fields:

field_single_date_calendar_event
field_additional_dates_cal_event

I only can get the first field to show up on my calendar. I can interchange them but I can't see both at the same time. NOTE: the error doesn't show up when trying to implement this set-up.. because I have gotten rid of the "From and To" option.

Is this abnormal? Or is this normal for FullCalendar at this stage. Thanks again.

Not sure about the issue with an empty field. That could use more testing.

As of right now, the calendar uses the first valid date field. If its a multiple value field, its added once for each. But not once per date field...

ah. Ok, that makes me feel better. Thanks. I can't quite pin down right now when I get the error or why but a number of people have issues with this type of Warning over at date.module http://drupal.org/node/518816

Will update this if I can be of help.

Earlier you stated, "If its a multiple value field, its added once for each. But not once per date field..." Do you think down the road we'll be able to add another date field? So that a user can add a date for 'field A' and then add a date for 'field B' and see both fields as a result of creating this node?
