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

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

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 cool, i'm going to spend tomorrow morning trying to reproduce the issue using the code you sent as a foundation. I'm hoping i'll be able to reproduce the issue and identify if its just something gong on in the application or if we just need to make a fix on our side, in which case I'll make the fix and get your a private build ASAP.

I'll keep you posted either way.

-SteveZ

Steve,

I have stripped the code and commented most of the code in the UIViewController. Still 4 calls to asyncAppointmentRequest. Files are in the attachment.

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?

-SteveZ

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?
