I have a Xamarin Forms PCL project with some sfNumericTestBoxes.
Using VS 2017, Xamarin Forms, sfNumericTextBox
When a sfNumericTextBox has input focus and the Enter key on an iPhone/iPad keyboard is pressed the app crashes with an NullReferenceException, see debug output below. ( No problems on Android and UWP).
Attached is a demo app I downloaded from Syncfusion forums, the crash also happens here.
Debug Output:
2017-08-31 08:41:16.292 NumericTextBoxIntegerSupport.iOS[2482:1132627]
Unhandled Exception:
System.NullReferenceException: Object reference not set to an instance of an object
