React error after reparenting #31

Closed toschlog closed 2 years ago

toschlog commented 2 years ago

I recently started using react-reparenting and it was a huge win. Thank you so much.

However, I'm sometimes getting an error in the render after reparenting. I assume I'm doing something bad but I'm not sure what it is. I'm continuing to investigate, but I thought I'd post the error here in case anyone has seen it before and has some useful information.

Uncaught Error: Expected to find a host parent. This error is likely caused by a bug in React. Please file an issue.

I've resolved this issue, I think. I was calling the reparent function before the first render, when there were in fact no parents. It didn't crash when I did that, but it seems to have caused the crash down the line.
