Hey Daan, 

Thanks for the sample. 

The Calendar is actually working correctly. However, when the WeekView request the appointments, there aren't any appointments available yet. 

Thats b/c in the sample, the appointments from the CSV are being loaded in a background thread. 

So when the calendar asks for appointments for that specific point in time, there are no appointments available. 

If you don't load the CSV in the background, then it works fine. Or you could call invalidate after the appointments are loaded and reloaded the calendar view. 

Hope this helps,

-SteveZ

Thanks for the reply,

I have removed all the NSOperation code and it still works. The invalidate I still need to display the initial data in the week view. This is probably because of another bug I mentioned before: In the week view the asyncAppointmentRequest is called too many times.

Let me try to explain my theory:

The first asyncAppointmentRequest adds the current month to the months array but it is not the current week call. While this call is getting data from the web service the second  asyncAppointmentRequest is called with the correct week which is displayed. At this moment the web service call has not finished and the appointments array is empty. If you could fix the issue where the asyncAppointmentRequest is called too many times that would fix my issue and then I can remove the invalidate call from the request.

Hey Daan, 

Yes, so if too many requests are occurring, the current request object you had, would no longer be valid, and thus you would run into the issue. So, yea that makes sense. 

Problem is, I don't see that happening. 

You should see 2 requests when a particular View loads. One for the current week/month/day and one for the next week/month/day. 

Then when you scroll, you should see one additional request, as the calendar always keeps 2 date ranges in scope. 

I've attached my sample. if you could run it, could you let me know if you see what i'm seeing or if your still seeing multiple requests. 

Thanks,

Steve,

I see this is only the following method that is called many times but I guess that's no issue:

-(void)calendarView:(IGCalendarView *)calView weekChanged:(NSDate *)date

I've added some logging in the asyncAppointmentRequest and notice the two calls are done duplicate and that explains the no data displayed initially.

Here is the logging:

2015-12-14 17:37:08.631 Gensys[10110:299696] Start of async request

2015-12-14 17:37:08.632 Gensys[10110:299696] request.start == 2015-12-12 23:00:00 +0000

2015-12-14 17:37:08.632 Gensys[10110:299696] request.end == 2015-12-20 22:59:59 +0000

2015-12-14 17:37:08.632 Gensys[10110:299696] Month doesn't exist

NOW THE WEB SERVICE CALL IS DONE

2015-12-14 17:37:08.633 Gensys[10110:299696] Start of async request

2015-12-14 17:37:08.634 Gensys[10110:299696] request.start == 2015-12-19 23:00:00 +0000

2015-12-14 17:37:08.634 Gensys[10110:299696] request.end == 2015-12-27 22:59:59 +0000

2015-12-14 17:37:08.634 Gensys[10110:299696] Month exists

2015-12-14 17:37:08.663 Gensys[10110:299696] Start of async request

2015-12-14 17:37:08.664 Gensys[10110:299696] request.start == 2015-12-12 23:00:00 +0000

2015-12-14 17:37:08.664 Gensys[10110:299696] request.end == 2015-12-20 22:59:59 +0000

2015-12-14 17:37:08.664 Gensys[10110:299696] Month exists

2015-12-14 17:37:08.670 Gensys[10110:299696] Start of async request

2015-12-14 17:37:08.670 Gensys[10110:299696] request.start == 2015-12-19 23:00:00 +0000

2015-12-14 17:37:08.670 Gensys[10110:299696] request.end == 2015-12-27 22:59:59 +0000

2015-12-14 17:37:08.670 Gensys[10110:299696] Month exists

NOW THE DATA COMES BACK FROM THE WEB SERVICE

I can't put my finger on why the call is duplicate. When I scroll horizontally to other weeks I still don't see any data. I disabled most other code and still no fix.

Hmm.. 

So to be clear, my sample was working for you, right?

If so, that means we're at least seeing the same thing there. So the question is, whats different in your actual application versus my sample? 

The only thing that should trigger another appointment request call, would be calling invalidate somewhere on the calendar? 

Can you take a look at your code, and make sure you're not doing that somewhere else in your code? 

-SteveZ

Yes the sample is working. I have been debugging and debugging last couple of hours. I added two screenshots in the attachment, both are executed twice, the first twice and then after that the second twice. It's not the selectedIndex on the tabbarcontroller cause I already called the CalendarViewController as a simple presentviewcontroller on another button and it gives me something else but is still called four times.

There is also the CalendarViewController header and implementation files. I truly have no idea what's going wrong or what i'm doing different than in your example besides using AFNetworking to retrieve the data.

Just wanted to tell that the support so far has always been great at Infragistics :-)

Hey Daan, 

Ok, so its definitely using the same build. 

Maybe you can try using Sync callback with your simplified sample, and see if thats getting called 4 times?

Perhaps the projects are using different versions of the IG Framework?

Can you insert the following line of code, in both the sample application, and in your actual app?

NSLog(@"%@", [IGBuildVersion buildVersion]);

I just want to make sure that your application isn't holding on to an older version. 

-SteveZ

I see the sample and everything working fine there. The only other difference I see is that you are using a storyboard where as we're using seperate xib files for the user interface.

I'm running out of ideas and without the CalendarView source code there is no way I can debug the issue. As you saw I stripped the entire code and do a simple call to the UIViewController. Nothing special just like in your sample.

Therefore I also checked the project settings and made some changes there. Also no result.

Hey Daan, 

Thanks for the stripped down version. 

I tried it out, and cleaned out all the commented code, but its still not happening for me. 

I've attached the sample. Can you verify your'e seeing the same thing?
