Fullcalendar: draggable object rejects fullcalendar as droppable even though fullcalendar accepts drop
I have set up FullCalendar to accept drops, which it does. But the draggable object, which I have constructed with revert:'invalid' does not seem to recognize the dates on FullCalendar as droppable, and reverts back. Here is my code:
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd">
<html><head>
<meta content="text/html; charset=ISO-8859-1" http-equiv="content-type">
<title>mydrag</title>
<script src="fullcalendar-bundle.js" type="text/javascript"></script>
</head><body>
<div id="mydrag" style="width: 200px; height: 100px; background-color: red;">My Drag</div>
<div id="calendar"></div>
<script type="text/javascript">
function onExternalEventDrop(date, allDay) {
alert("Dropped on " + date + " with allDay=" + allDay);
}
$('#mydrag').each(function() {
// create an Event Object (http://arshaw.com/fullcalendar/docs/event_data/Event_Object/)
// it doesn't need to have a start or end
var eventObject = {
title: 'MyDrag Title'
};
// store the Event Object in the DOM element so we can get to it later
$(this).data('eventObject', eventObject);
// make the event draggable using jQuery UI
$(this).draggable({
helper: 'clone',
//revert: 'invalid',
revert: function(droppableObj) {
//if false then no socket object drop occurred.
if(droppableObj === false) {
//revert the .myselector object by returning true
alert('Not a droppable object');
return true;
}
else {
//droppableObj was returned,
//we can perform additional checks here if we like
//alert(droppableObj.attr('id')); would work fine
//return false so that the .myselector object does not revert
return false;
}
},
revertDuration: 500, // original position after the drag
start: function(e, ui) {
$(ui.helper).css('width', $(this).css('width'));
}
});
});
$('#calendar').fullCalendar({
aspectRatio: 2.25,
header: {
left: '',
center: 'title',
right: 'prev,next'
},
columnFormat: {
month: 'dddd'
},
droppable: true,
drop: onExternalEventDrop
});
</script>
</body></html>
When I drag the draggable element onto the calendar, the element reverts back (suggesting that the calendar date was not recognized as a valid droppable)....but the drop callback is triggered with the expected alert (suggesting that FullCalendar recognized the draggable as valid). I would expect that the draggable should not revert back. Am I doing or expecting something wrong? I have searched all over, but not found anything to explain this. Any help would be greatly appreciated.
Update: Forgot to mention, what I have called "fullcalendar-bundle.js" is a file containing the following:
- jquery 1.5.2
- jquery ui 1.8.11
- fullcalendar 1.5.2 plugin
Another update: I have just tried the FullCalendar 1.5.3 release, but see the same behavior.

This may help you:
working version of drag and drop : http://jsfiddle.net/wkKfB/15/
Solution for dragobj = false is that you need to bind droppable event to the calendar so that draggable knows what DOM object is droppable see working example here: http://jsfiddle.net/CZQkm/3/ && http://jsfiddle.net/DEsdN/12/ *Until here
(Your version but with some tweaks. By the way I have jsfiddl-ed your issue here: http://jsfiddle.net/wkKfB/16/) (issue was binding the external event)
Good documentation reside here: http://arshaw.com/fullcalendar/docs/dropping/droppable/
Issue was you need to externally add these drag event.
You can change the css and make it to your use.

To capture the external event you need to add this code but the sample above has all set for you and should be clear
/* initialize the external events
-----------------------------------------------------------------*/
$('#external-events div.external-event').each(function() {
// create an Event Object (http://arshaw.com/fullcalendar/docs/event_data/Event_Object/)
// it doesn't need to have a start or end
var eventObject = {
title: $.trim($(this).text()) // use the element's text as the event title
};
// store the Event Object in the DOM element so we can get to it later
$(this).data('eventObject', eventObject);
// make the event draggable using jQuery UI
$(this).draggable({
zIndex: 999,
revert: true, // will cause the event to go back to its
revertDuration: 0 // original position after the drag
});
});
/* initialize the calendar
-----------------------------------------------------------------*/
