Field ordering during before randomization process

[ivicelig]

Hi,

I was wondering if there is possibility of implementation for some kind of ordering functionality of fields before they get populated (after retrieval of declared and inherited fields). My problem is that I have object, and that object has two fields (Country and City). When I get random country I would like to create randomizer which would based on country select random city from that country.
If I fetch current object from ContextAwareRandomizer I can't be sure that country has already been filled in, so that's why I would like to set some ordering to fields to make sure country is populated first.
