RE: [flexcoders] How to access objects made by a script (addChild)

[Tracy Spratt]

Setting the id this way is not the same as setting an id="myId"  in an
mxml tag.  In that case the generator/compiler creates an instance
variable with the name specified in the id property containing a
reference to the component.

 

When creating children yourself, you need to build your own list of
references.  One way is using an object (associative array)

 

_oTBArray['tabnav'+ dp[i].id] = newTB;

 

Then access it:

var tbCurrent:TabNavigator = _oTBArray['tabnav'+ dp[i].id];

Subject: [flexcoders] How to access objects made by a script (addChild)

 

In a script I iterate through a collection, making new TileLists as we
go along. I name these tilelist's so I can access them later.
Snip #1
for (var i:int=0; i<dp.length;i++) {
// First we make a new tabbar for the tiles
var newTB:TabNavigator = new TabNavigator();
newTB.id = 'tabnav'+ dp[i].id;
newTB.percentWidth = 100;
newTB.height = 200;
// Then we make a canvas to hold the items
var newCV:Canvas = new Canvas();
newCV.id = 'canvas'+ dp[i].id;
newCV.percentWidth = 100;
newCV.label = dp[i].orgname;

// Then we make a new TileList
var newTL:TileList = new TileList();
newTL.id = 'tilelist'+ dp[i].id;
newTL.name = 'tilelist'+ dp[i].id;
trace('create:tilelist'+ dp[i].id);
newTL.percentWidth = 100;
newTL.itemRenderer = new ClassFactory( projectTile );
newTL.dataProvider = null;

newCV.addChild( newTL );
newTB.addChild( newCV );
pageOverviewVBox.addChild( newTB );

g_fileid = dp[i].id;
ds_getpages.send();

}
// End snip #1

For each of these items, I call a httpservice to get the pages that
belong to that file (ds_getpages.send())

>From the data returned I can calculate the name of the tilelist where
I'd like to show the data. See Snip #2
{
var rawData:String = String(event.result);
var arr:Array = (JSON.decode(rawData) as Array);
var dp:ArrayCollection = new ArrayCollection(arr);
//projectPages = dp;
var fileid:int = dp[0].fileid;
trace( 'tilelist'+fileid as TileList);
//(('tilelist'+ fileid.toString()) as TileList).dataProvider = dp;
<- Fails with a NULL error, can't access a null object... 
}

So.. please help me out here - how can I access a object, which
name/id I know - I just cant figure this out. Propably doing this all
wrong - but this is what I could think up.

Thanks for your time (if you made it all the way down here)
