Rotator error with SfDataForm

[Gabo]

Hi! 

I have a Xamarin.Forms app in which I need a SfDataForm inside a SfRotator. I am getting this error on iOS 13 but in Android it seems it works just fine!

Could you please help me?

This is the error and the stack trace:

Object reference not set to an instance of an object

at Syncfusion.XForms.iOS.DataForm.SfDataFormViewRenderer.LayoutSubviews () [0x00000] in <14d11d2b95b64e36a3ef086e1791afa7>:0

Thank you!!

Thank you for your response! It seems that is a problem with another plugin that I am using (Rg.Plugins.Popup) with my project in combination with SfRotator and SfDataForm. 

But the exception is on SfDataForm.

Would you please help me with a patch or something? Because I need to use Rg.Plugins.Popup in combination with SfRotator and SfDataForm.

In the attached example you can see that it works on Android but in iOS fails.

Thank you!!
