Accept iterables and collections as children.

[rodogir]

React supports rendering of iterables and collections as childrens. react-tree-walker does not support this at this moment leading to unexpected results when using Iterables (e.g. List from immutable-js) as children. Subtrees that are rendered in react are might be skipped by the visitor.

I created a minimal example that shows the issue: https://codesandbox.io/s/o9kzlrql86

Here are some links from the original react discussion: Original Issue Original PR

Would be great to have this feature!

I've accomplished this in a fork using code lifted from the React merge that allowed for iterator functions: https://codesandbox.io/s/pj998lr3lj

Would you accept a PR w/ test that clears this issue @ctrlplusb? My version of the library is quite a bit different at this point (removed Preact stuff, breadth-first resolve rather than depth-first to allow for concurrency, added more strict element type checks etc), but I can try to make a PR as simple as possible for you.

Otherwise you can obviously just lift those sections on your own.
