Possible bug in group fieldtype validation

Start by comparing the submitted request with the entry blueprint, especially the two nested groups that each define a required link field. Reproduce the save with both links set to the same value and inspect how group field validation handles those repeated keys. Done means both submitted values are preserved and the required validation message is not shown incorrectly.

Bug description

When trying to save my entry, an invalid missing field message is shown. I am using an entry containing a group "hero" with 2 field groups named: hero_card_left and hero_card_right. Which both hold call to action properties. In this case upon saving this group with 2 of the same value for link. The value is left empty when submitting the form and thus the required message is shown.

Using the same value 'test.nl' for Link

Portion of the request send to form handler. The first link value is set to null even though I set it to test.nl.

How to reproduce

• Create an Entry
• Add a field group
• Add 2 groups (left or right) inside that group with the same keys
• Use the same value for in this case 'Link'
