Problem with Complex.

[prosvitco-artur]

I have found an issue.
When adding new Groups, their IDs are generated using this function.

const ALPHABET = "Uint8ArdomValuesObj012345679BCDEFGHIJKLMNPQRSTWXYZ_cfghkpqvwxyz";
export default function uniqueId() {
	return "cf-${generate(ALPHABET, 21)}";
}

As we can see, the string uses the character '_'.
There is a small probability that this character will appear twice (but the probability exists, and it has happened to me three times in one day, you could say I won the lottery).

What’s the problem, you ask? The problem is that in this function:

handleGroupFieldChange = (fieldId, fieldValue) => {
	const {
		id,
		value,
		onChange
	} = this.props;

	onChange(id, produce(value, (draft) => {
		const path = fieldId.split('__');
		const fieldName = path.pop();
		const group = find(draft, ['_id', path.pop()]);

		set(group, fieldName, fieldValue);
	}));
}

the string is split using '__', and in my case, these fields are not being saved. Therefore, please remove the '_' from the ID generation string in one of the upcoming updates!
