I recommend you to take a look at Crosslight FormBuilderSamples. Navigate to Editors > List View > Navigation section. The sample shows how to add ListView on FormBuilder.

I tried to run the sample on iPhone 6s iOS 9.2 (emulator) without any problem.

Please feel free to let me know if you find anything that I might miss during my attempt to reproduce the problem.

Any updates? 

Sorry for the delay in sending this.

The reported problem has been forwarded to Crosslight development team to be investigated further. It is filed under CROS-1026.

I found that the problem is specific with nested-modal using FormBuilder scenario. I did the following test and found that the problem doesn't persist.

• Use nested-modal without FormBuilder
• or Use Push NavigationMode
  Set the NavigationMode to Push in SimpleViewModel.cs (as shown in the following snippet code).

private void ShowToast(object parameter)
{
	var p_Parameter = new NavigationParameter()
	{
		ModalPresentationStyle = ModalPresentationStyle.FormSheet,
		NavigationMode = NavigationMode.Push,
		EnsureNavigationContext = true
	};

	this.NavigationService.Navigate<LocationListViewModel>(p_Parameter);
}

I will keep this thread updated with any news I heard from the team regarding CROS-1026.

We can't possibly do this because the app features a modal context. Understand that this is a live app in production and requires immediate attention. The modal context is an existing feature with Crosslight, so we're hoping that this bug should not be taken lightly. That workaround just won't work with our app. Thanks!
