Hi Mone,

I am using the latest version of Lightstreamer. I downloaded it just a week back.
Code:
Lightstreamer Flash/Flex (Native AS) Client Library version 1.1 build 33
Compatible with Lightstreamer Server since version 3.5
Also, I have attached a log on my first post which contains LightstreamerLogger.subscriptions as DEBUG and the Flex log of the above.

The code is this:
Here fields is an array of Strings with required fields.
And itemname is the subscription item.

Code:
		public function subscribe(itemName:String,fields:Array):void{
				var nonVisualTable:NonVisualTable = new NonVisualTable(new Array(itemName),fields,"MERGE");
				nonVisualTable.setDataAdapter("MBTLSADAPTER");
				nonVisualTable.setSnapshotRequired(false);
				nonVisualTable.addEventListener(NonVisualItemUpdateEvent.NON_VISUAL_ITEM_UPDATE,onChange);
				lsclient.subscribeTable(nonVisualTable);
				if(!dictionary.hasOwnProperty(itemName)){
					dictionary[itemName] = new ArrayCollection();
				}
				ArrayCollection(dictionary[itemName]).addItem(nonVisualTable);			
		}
