Object value selector or dropdown list box populated by ABSL?

Hi Gurus,

Is it possible to populate Object value selector control or dropdown list with result of RESTapi response with json/or parsed values from json.

If yes, is there some tutorial?

In Custom BO I have:

node gradList [0,n]{
element listID		:ID;
element	grad		:LANGUAGEINDEPENDENT_EXTENDED_Text; 
		}

this values are populated on action (following code is part of loop which extracts RESP api response, and result is more than one entry) :

var n = this.GetFirst().gradList.Create();
i=i+1;
n.listID =i.ToString () ;
n.grad= firstElementString;

After that in UI designer I create dropdown list box and bind it to

gradList.grad

The result is that I in dropdown list box receive only the last element, all others are lost :-(

Please help where is the problem, or please suggest Is there some other way (eg.OVS...)

br,

Zoran Galijanic
