Hey! Thanks for your comment.

I don't currently use React Native for anything, so "try it and see" amounts to "set up and learn a whole React Native dev environment", which I don't have time for.

However, I'd be happy to accept a pull request that fixes this. Do you have any idea where it goes wrong? Do you know whether it worked on earlier versions of React Native?

Hi, yes, sorry I should have been more detailed. It worked in React Native 0.38.x. Unfortunately, I have no idea where it is going wrong, as I am not very familiar with babel plugin architecture in general, and even less so with this specific plugin.

What I can say for sure is that after upgrading from 0.38 to 0.39, our react component classes no longer had the static property displayName at run time.

Impressive. In all honesty I have no good idea where to look. The RN changelog doesn't say anything about a change in how the react component base classes work or something.

You could help by making an example app of the tiniest possible RN application which exhibits this problem. I'm curious whether the babel output contains the displayName property correct in that setup, and whether it changed between RN 0.38 and 0.39. If there's no change there, then I'd wager there's no real bug in this plugin per se but RN does something to overwrite or remove the displayName property at runtime.

If that's the case, maybe we can come up with a workaround.

I think making an example app of the tiniest possible RN application which exhibits this problem is a great idea, but unfortunately, I won't be able to get to this anytime soon.

Ok. I'll leave this issue open in case someone else gets in trouble because of this and has an idea. Thanks for reporting!
