[flexcoders] Get parent object in an array collection

[timgerr]

Hello all,
I am using an array collection as a dataprovider for the Kap Lab
(http://lab.kapit.fr/display/visualizer/Visualizer) which is like a
spring graph.  So when I click on an end node, I get the id of the
node. If I have an id to an object, how can find the parent object and
get access to it?  Has anyone done this before?  Here is my
ArrayCollection:

private var myDataProvider:ArrayCollection = new ArrayCollection([
{Region:"Southwest",ID:"1", children: [
     {Region:"Arizona",ID:"2", children: [      
        {Territory_Rep:"Barbara Jennings", ID:"3"}, 
        {Territory_Rep:"Dana Binn",ID:"4"}]},  
     {Region:"Central California",ID:"5", children: [ 
             {Territory_Rep:"Joe Smith", ID:"6"}]},  
     {Region:"Nevada", ID:"7", children: [ 
             {Territory_Rep:"Bethany Pittman",ID:"8"}]},  
     {Region:"Northern California", ID:"9", children: [ 
             {Territory_Rep:"Lauren Ipsum",ID:"10"}, 
             {Territory_Rep:"T.R. Smith",ID:"11"}]},  
     {Region:"Southern California",ID:'12', children: [ 
             {Territory_Rep:"Alice Treu", ID:'13'}, 
             {Territory_Rep:"Jane Grove",ID:"14"}]}
]}
]);

Thanks for the read,
happy TGiving ,
