Unhandled exception when clicking on far away from a message in SfChat

[Vassili]

Hi, I am getting an unhandled exception after adding SfPopup widget to the Chat one (see below).

I defined all the tap events for the messages in chat and all works fine till I click on some distant area within the SfChat widget.

Unfortunately I have no access to the code on top of the exception stack, but it looks like simply swalloing this internal exception will solve it.

Thanks, Vassili

P.S. Actually same problem is with double tap. To reproduce you can have just one message in the chat area and then subscribe like this:

            sfchat.MessageTapped += Chat_MessageTapped;

            OR:

            sfchat.MessageDoubleTapped += Chat_MessageDoubleTapped;

Then if you tap or double tap somewhere in the empty area far away from any message, the exception occurs and the stack trace is the following:
