kendo-react-conversational-ui React Warning

[Antonios]

Basic use of the Kendo React Conversational UI, causes a React Warning

Warning: Each child in a list should have a unique "key" prop.

Check the render method of `NewMessage`. See https://fb.me/react-warning-keys for more information.
    in input (created by NewMessage)
    in NewMessage (created by Chat)
    in div (created by Chat)
    in Chat (created by App)

 

simply open in stackblitz the example on https://www.telerik.com/kendo-react-ui/components/conversationalui/ and check the developer tools console output.

 

I am not sure when this started to happen, because it was not an issue in the past but I noticed it recently...

Hello, Antonios,

Thank you for reporting this.

This is indeed a new warning caused by a new feature:

https://www.telerik.com/kendo-react-ui/components/conversationalui/custom-rendering/

We will add the missing key prop as soon as possible, and the warning will disappear:

https://github.com/telerik/kendo-react/issues/359

As it is just a warning, please feel free to use the current version, it should not affect the component.

Additionally, I have added some Telerik points to your account for bringing this to our attention.

Regards,
Stefan
