Description Daniel Hindrikes 2015-06-05 04:21:15 UTC
I hava a map with pins that shows where stores is located. When I click on a pin I want mote information about the store. But on iOS the click event is triggered for the wrong pin. It working for Windows Phone and Android. I'm using the latest stable version of Xamarin.Forms and Xamarin.Forms.Maps (

In the code below, pinStore.Key will be the pin. 

var stores =  ViewModel.LoadPinsForStores();
foreach (var pinStore in stores)
     pinStore.Key.Clicked += (s, a) =>
            Navigation.PushAsync(ViewFactory.CreatePage<StoreDetailsViewModel, Page>((view, page) => view.StoreId = pinStore.Value.Id) as Page);

Thank you for taking the time to submit the bug. We tried to reproduce the issue you reported but were unable given the description. If you could please attach a reproduction to the bug by starting with a clean Xamarin.Forms project and adding just the code necessary to demonstrate the issue we would very much appreciate it.

Warm regards,
Xamarin Forms Team

I have created an attachement with a Xamarin.Forms project. I have hard to recreate the bug first, but when I zoomed in  and panned around in the map I got the same behavior here. Not on all pins but on many of them. You can see that the store name not is the same on the pin label as on the page that load when you click the label.

Can you send me a screencast? i m not being able to reproduce, if you open the pin and click the detail you will always get the right page.

I cannot duplicate this in 2.3.3-pre4. Can you re-test?

I was not able to reproduce this issue using the attached repro and the following Forms versions: GOOD   GOOD
2.3.4-pre2: GOOD

If you are experiencing this issue or a similar one with Forms or newer, please file a new bug report with as many details as you can and include a reproduction case if possible. Thanks!
