Default User() not updating on datacard during form submission

[DCHammer]

Ok, I am embarassed that I can't figure this out on my own but here we are. I've been at this for 2 hours and can't figure it out.

This should be really easy. It's just a datacard on a form and I want to default a selection. The datacard is hidden so users can't modify what's being saved but other than that, it's basic functionality.

Let me describe the use case.

I want to default a RequestedBy field. I don't want to use the default CreatedBy field that exists in every SP list because my use case requires the ability to modify the RequestedBy in certain conditions.

I have a datacard connected to the field that will be hidden when the form is in New mode.

Datacard.Default = ThisItem.'Requested by' (I actually have a varItem global that I should be using but I'm going to leave it with the gallery selection until I make this work.)

Datacard.Update = DataCardValue8.Selected

DataCardValue8.Items = Choices([@'SPIFF - Requests'].HiringManager) (Ignore the disconnect in the names. This is a result of copying a SP list and I've vowed to never do it again.)

DataCardValue8.Default = NULL

DataCardValue8.DefaultSelectedItems = User() (I'm about 99% sure this setting is my problem but don't know how to fix it. )

I can figure out how to allow editing when the form is in Edit mode after I get it to save the current User() into the right field on creation.

Thanks for the assist in advance.

Would be handy if there was a delete Post function. I actually asked this same question a week ago and answered it myself. 

If you're setting a Default on a User select dropdown or combobox, you have to do this funky 

{Claims: Concatenate(
            "i:0#.f|membership|",
            User().Email// Person email
        ),
        Department: "",
        DisplayName: User().FullName,
        Email: User().Email,
        // Person email
JobTitle: "",
        Picture: ""}

Claims thing. Instead of simply putting User() into the Default property for the dropdown or combobox, you have to use the above.
