Not easily at the moment.
However, thanks to your suggestion of trying to create the sheet every time
I've figured out the error (on my part).
In my code I had
if (sheet == null)
{
create it, etc.
}
sheet.Click +=….
The Clicked handler was getting += each time through that the user clicked on
the add photo button. Thus it was calling it twice which explains why it was
complaining about the active controller as the Image Picker was being displayed
twice.
The sheet.Clicked += should have been inside the if (){} block. :)
Thanks,
Gerry
