Just as an addendum... I also had enum values in the mysql table that also
set a default and also DID NOT have the not null set. They inserted a
default value into the database with the update and simple FormFu YAML

HOWEVER... I just noticed that the Form is not displaying the default

Q1: How can I get FormFu to show the default as the selected value?

Q2: Can I have it automatically fill the enum values into a select field? I
did not try to do this in my controller and send it to the options of the
element as done in the Catalyst example since I was having troubles
somewhere with getting those to update well and have set that aside for the
moment. I was not sure how to do this... but looking here I may just need
to somehow send the type.extra.list as the options in my controller?

        my @TypeList =3D
        my $TypeSelectOptions =3D $form->get_element({name =3D> 'type'});
        $TypeSelectOptions ->options(\@lTypeList);

I am certain that the first line is wrong but I have no idea what I can
call on $c-> model to get the enum list out. I am still learning so any
help is very much appreciated.

In mysql I have...
  type          enum('business', 'personal', 'reimbursed') default

In the Schema::Result::  I have
    data_type =3D> "enum",
    default_value =3D> "personal",
    extra =3D> { list =3D> ["business", "personal", "reimbursed"] },
    is_nullable =3D> 1,

And in the YAML form definition I have
    # Type
    # Manually set the select items for enum types? No auto fill?
    - type: Select
      name: type
      label: Type
        title: Reimbursed is for things we buy for clients that has been
reimbursed financially.
        - ['business', 'Business']
        - ['personal', 'Personal']
        - ['reimbursed', 'Reimbursed']
