I have a rather complex project in making a custom field type, and I can't seem to figure out how Gravity Forms is getting and storing the information posted from my custom inputs.
Our client wanted something similar to the new List field functionality, but they wanted a list within a list, so I made a Custom List field type. It works on the form display, but when the form is filled out and submitted, I'm having trouble getting the input values to show up in the entries display. I've tried storing everything in an array just like list fields, but the array comes up empty on the entry detail page.
This is all the code I've placed in our theme's functions.php:

The filter at the bottom, gform_entry_field_value, is what I'm confused about.
This is the form on our test site:

To see the custom field, set "Are you registering multiple service locations?" to Yes.
