			cell.SetBinding (TextCell.TextProperty,"[0]");//here is the path
			list.ItemTemplate = cell;

Comment 1 Paul DiPietro [MSFT] 2016-03-10 19:43:15 UTC
A reproduction project would be appreciated in helping to investigate this issue.
Comment 2 Jason Smith [MSFT] 2016-03-13 11:57:39 UTC
The actual error is missing from the stack trace too. We would at the very least like that. Looks like a linker issue.
Comment 3 Jaekov 2016-03-13 13:30:56 UTC
I could provide a reproduction project. 
Basically it's about binding a List<string[]> myList to a ListView in Xamarin forms PCL project.

Comment 6 Chris King 2016-04-28 19:23:29 UTC
I show no reproduction on master iOS nor Android.
Comment 7 Jaekov 2016-04-28 19:37:54 UTC
Did you run the project on a real ios device? 

The error only appear when is launched on an iPhone.
Comment 8 adrianknight89 2016-12-17 02:18:34 UTC
