[Bug] [iOS] Unable to open second level popup (e.g. to open popup B from popup A)

[bondarenkod]

Description

iOS platform: Unable to display child popup when another is presented.
When you are trying to present child popup you can observe the following message in the Output window:

[Presentation] Attempt to present <Xamarin_CommunityToolkit_UI_Views_PopupRenderer: 0x7ff59af2f1c0> on
<Xamarin_Forms_Platform_iOS_PlatformRenderer: 0x7ff59ac0d750> 
(from <Xamarin_CommunityToolkit_Sample_iOS_Renderers_NoLineNavigationPageRenderer: 0x7ff59d0ea400>) 
which is already presenting <Xamarin_CommunityToolkit_UI_Views_PopupRenderer: 0x7ff59a90f2b0>.

This is happening because the popup control renderer is trying to be displayed on the same ui view controller twice.

I tried a small POC workaround, where I displayed the child popup using the parent popup view controller and it worked as expected:

Will there be any fixes about this issue?
Android works good but iOS cant open Popup from a Popup.

Not yet, my solution is poc only, more work is required.

I am having this issue also. Hopefully, a fix is in the pipeline.

@bondarenkod are you using .NET MAIU already? If so I would like to know if you are able to try the Popup on CommunityToolkit.MAUI, I know this issue lives there as well, but I'm wondering if your fix will work there, if so let me know and I can make an effort to implement it on GA

Hello! I'm sorry for the delay, I had to wait till the weekend. Also, I'm struggling with testing the project due to issues with my copy of VS2022. The VS randomly display target devices in the window, in 3 hours I've seen full set of attached devices only one time. That allowed me to complete the test on the Android device. So, the iOS part will be added a bit later, I'm going to reinstall the VS again.

Test results, child popup working as expected at:

• iOS - TBD
• Android - YES
• Windows - NO

@bondarenkod relax, take your time (: and thanks for looking into this.

I'm afraid that windows doesn't support this scenario, maybe we can block the LightDismiss feature and only allow the removal of popups when the user clicks on something inside the presented popup.

I did a clean setup for win & vs 2022 preview on virtual machine.
I am still not able to see any targets except local 'Windows machine'.
Will wait till the next update, maybe it will help.

@bondarenkod just to make sure, are you using the latest VS 2022 preview? And are you checking the Xamarin workload option on installer?

I'm guessing there hasn't been any movement on this issue since April? I have encountered it myself testing some nested popups in iOS 16.

Do we have any solution for this issue in Xamarin forms ?
