Array validation function is getting a nuimber instead of an array

[ahmedHusseinF]

Bug Report

When an array is nested in a tab, validation is broken while creating/editing.
The array value is passed as a number probably its size.

If this is a real issue, it might trigger a breaking change with its fix

Steps to Reproduce

There is a demo repo where this is reproduced.
navigate to http://localhost:3300

1. Have a top-level Tab structure
2. Have an Array as a field in a Tab
3. Have a dummy field inside the array
4. The array validation gets a value of either undefined/(potentially array size as number)

Other Details

Firefox v108.0

Hey @ahmedHusseinF — this is indeed deliberate. The array field itself validates based on how many rows it has, although we could potentially update this in the future like you've mentioned.

In the meantime, the validate field does indeed accept siblingData as a prop, so you should be able to access the data for the entire array and still write a custom validation function that is based on the array's data in its entirety.

Would that solve for what you're looking to do? I will bump this over to a feature request and we can keep the conversation going there!
