Description Loan 2015-04-21 21:59:06 UTC
I am using Xamarin.Forms for developing apps for Windows Store.

I have a listview of messages which is bound to an ObservableCollection of groups. The list groups the messages by day then the messages show in order of the time - pretty standard stuff.

The problem I have now encountered is that in Windows Store- using the Add function to add new groups to the ObservableCollection causes an unhandled exception to fire.

I can get around this by using the AddRange function and simply adding the item I want to add to another "temporary list" first, then add that temporary list to the main Collection - This gets around it but seems a bit of a hack.

Is this the same issue as bug 29288? If not, I'll need the exception/stacktrace and some sample code that demonstrates the issue.
