I use this method to retrieve my multiple source events:

http://arshaw.com/fullcalendar/docs/event_data/events_function/

$('#calendar').fullCalendar({
    eventSources: [
        // your event source
        {
            events: function(start, end, callback) {
                // ...ajax first source retrieve
            },
        },
        {
            events: function(start, end, callback) {
                // ...ajax second source retrieve
            },
        }
    ]
});

If the 2 sources as above contains events, it will load in the calendar. However, if one of the sources contains 0 record,  all the events doesn't load. A bug?

I think I found out what is the issue. My ajax function goes like this:

                     success: function( res ) {
                        var obj = $.parseJSON( res );
                        if( obj.bool == 1 ) {
                            var events = [];
                            for( var i=0; i<obj.data.length; i++ ) {
                                events.push({
                                    id: obj.data[i]['id'],
                                    title: obj.data[i]['title']
                                });
                            }
                            callback(events);
                        }
                    }

If there is no result, it doesn't calls the callback function and hence causes all other events from other sources do not load. Once I move out the callback function of the if( obj.bool == 1 ) it works fine. I think the documentation should highlight the fact that the "callback" MUST be called regardless of whether there are any results.

Though I find this strange as one source shouldn't affect the other...

glad you figure it out.

internally, fullcalendar waits for all event sources to return events before attempting to render events. since your callback isn't being called, fullcalendar sees the event source as taking forever.
