Each child in a list should have a unique "key" props

[fonghou]

Hi,

Since updating 2022.04.08-137, I start seeing Each child in a list should have a unique "key" props warnings in React dev build, downgrading to 2022.03.31-133 made it go away.

This may not be a rumext issue, rather than a side effect of upgrading to React 18 (or JSX runtime). However, it's bit strange that the warning message even showed up for components that do not use <li> elements. Is this expected?

thanks for the great library btw!

yeah, i have noticed it also, the latest releases are not pretty stable, and we are experimenting on upgrading to react;
I will notice here about the progress

there are something wrong with current approach jsx, and I will fix it soon.

Previously we have used the jsx production runtime (without warnings) on PROD and DEV builds, so some warnings are expected. But you are right that right now the warnings does not make sense in many cases...

new release uploaded to clojars 2022.04.10-141 that should fix the warnings, still does not tested on penpot codebase.
Additionally, right now we have some runtime checks for children prop being array or not, but I think this can be done on compile time at hikada so I expected to release more versions for optimize this part.

If you still experimenting some unusual warnings, please reopen this issue.
If you have other issues related to react-18 update, please open a separate issue

Thanks for the feedback in any case.
