Fullcalendar with JSON feed returning eventSource in extended form - fullcalendar

Question

I'm using the excellent fullcalendar by arshaw with Angular UI and right now I'm having a problem with eventSource objects in extended form not rendering when fetched as JSON feeds.
The data is fetched using the following code in the controller:
$scope.events = [
'/api/v1/users/104/events?format=cal&type=9',
'/api/v1/users/104/events?format=cal&type=10'
];
$scope.eventSources = $scope.events;
When the JSON feed returns an array with event objects it actually works:
// returned by - /api/v1/users/104/events?format=cal&type=9
[
{
url: "/#/events/86893",
start: "2013-03-15",
title: ": Event - 86893"
},
{
url: "/#/events/31348",
start: "2013-03-27T09:30Z",
title: "Event - 31348"
}
],
// returned by - /api/v1/users/104/events?format=cal&type=10
[
{
url: "/#/events/86899",
start: "2013-03-25",
title: ": Event - 86899"
},
{
url: "/#/events/31349",
start: "2013-03-17T09:30Z",
title: "Event - 31349"
}
]
However I would like to specify some options along with the event data, for example different colors for different JSON feeds. Hence I settled for the API to return the event source in its extended form . This is what it API returns.
// returned by - /api/v1/users/104/events?format=cal&type=9
{
events: [
{
url: "/#/events/86893",
start: "2013-03-15",
title: "Event - 86893"
},
{
url: "/#/events/31348",
start: "2013-03-27T09:30Z",
title: "Event - 31348"
}
],
color: "#ff9900",
allDayDefault: false,
ignoreTimezone: true
},
// returned by - /api/v1/users/104/events?format=cal&type=10
{
events: [
{
url: "/#/events/86899",
start: "2013-03-25",
title: "Event - 86899"
},
{
url: "/#/events/31349",
start: "2013-03-17T09:30Z",
title: "Event - 31349"
}
],
color: "#3366FF",
allDayDefault: false,
ignoreTimezone: true
}
Unfortunately this format isn't rendered when fetched as JSON. When fetching the extended format I changed the eventSources assignment somewhat to look like this:
$scope.eventSources = [ $scope.events ];
If I cut and paste the raw JSON response (with the event source in its extended form) from the API straight into the eventSources method it works. Isn't it possible to consume the event source in extended form when it is returned as a JSON feed?

Answer 1

Could it be that the eventSource being returned from the API is not where the extended form options should be used, but rather in the event functions used as the eventSource's.
The documentation states that the extended form should be used inside of the Json object used to call the API.
http://arshaw.com/fullcalendar/docs/event_data/events_json_feed/
If the API was too return the extra options for the events, then it would need to set each one individually.
Currently in this post, The only place I see where the extended options are called is from the returned api data.
I think this should be the other way around. And the calendar should know about the extended form before it even requests the data at all. This would mean the server will not need to return any extra options and the calendar will organize the event objects by feed and extended options.
If you could post a plunk, then we could nail this.
