Looping over objectElements in an arraycollection

I asked a simple question on flexcoders today:
I have a simple array collection. Ie. a ColdFusion query being passed back to Flex eg:

select  firstName, lastName, age
from    person

So in flex it's:

Ac[0].firstName = Paul  ect

But I don't know ac[0].columName so is there a way to loop over the properties of the object at ac[0]?
Thanks to Fotis Chatzinikos who game me this answer.

for (var key:String in object)
{
data = object[key] ;
}

where object is your arraycollection item ie. ac[0]

This was a simple solution that I just overlooked. I’m going to mock up an example of what I was using this for in the next few days.
