This won't work for nested arrays (e.g. some.1.foo.2.bar). You should instead take the last match I believe.

Updated to use matchAll and take the last match to handle nested arrays correctly. Also added a test for nested ArrayInput.

Nice! But could you also update the doc to make this new feature discoverable? E.g. in https://marmelab.com/react-admin/Inputs.html#linking-two-inputs
