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!

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.

If you looked at the error, I did mention the issue happens when closing the view. The error shows that it is an issue when using the NavigationService.Close() method. I have no problem running the sample as you have suggested neither do I have concerns when running our own code. The only issue is when using the Close() method. We used NavigationService because we had to close a modal master/detail context where the form view is loaded. This happens when clicking on Save and/or Done on the form view.

We've modified the sample file to replicate the error. We've added a functionality on "Update" button to launch a view on modal form. Click any item from the list, once on the Location detail view... a list of contacts should be in that form. Then click Done button (DO NOT click any item from the contacts list, it's not important), you should now receive the error.

Please use 4.0.5000.327

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.

Hi,

Please provide the syntax used with ListViewAttribute on forms with navigation mode. We tried the code below, but something goes terribly wrong when closing the form or view. It returns an error and crashes the app. See attached file:

[Editor(EditorType.ListView)]
[ListView(DisplayMemberPath = "ContactName", InteractionMode = ListViewInteractionMode.Navigation)]
[SelectedItemBinding(Path = "SelectedContactItem")]
public IList<LocationContact> Contacts;

Please review and see if anything else is needed. We also tried specifying the viewmodel type on ListViewAttribute but nothing works as opposed to what is expected.

Thanks!
