Datastore not showing array fields when trying to add or update

[sitestreet]

That's an excellent thread and explains exactly the issue I have. For some reason I completely missed that last year when it was posted.

My need for arrays is to create the same structure as required by PayPal Checkout. Please see this thread for the background:

Help needed with syntax for repeating within js - PayPal Checkout Cart

“items” in your JavaScript is expecting an array, so you can point to any array in your dmx app. “items”: dmx.app.data.myarray To find the actual path to your array, you can execute dmx.app.data in the dev console and find your array. Just make sure the array has the exact elements the js needs. You can always insert into a datastore in order to get the element names correct, and then point the js to that.

If you're able to just give me some example code then I'll happily hand-write it. I just need a steer in the right direction.
