It'd be very helpful it you'd provide more info about what causes
fill_formfu_values() to fail.
* the column name and type (definition)
* the field name and type and other settings
* the relevant value in the database

A Radio button is either On (checked) or Off (unchecked).
It should always have the value() set to something. This is what the
browser submits if the Radio button is checked.

It only makes sense to set default() to the same string as value().
If default() equals value(), then the Radio button gets checked="checked".
If they're not the same, it doesn't.

To summarize:

    ---
    elements:
      - type: Radio
        name: foo
        value: 'my-value'

then...

    if ( $rs->item_id eq 'my-value' ) {
        $radiobutton->default('my-value');
    }

Hope this clears things up,
