Answer 1

Deferred custom actions do not have access to public properties, except a couple of special ones, like "CustomActionData".

You can use an immediate custom action to set special property "CustomActionData" with the value of your property, and then from your deferred custom action read the value of "CustomActionData" instead of your property.
