I am looping through each item in an Array and for each item, I am trying to
create a new DataGrid on a new Canvas, and then add each Canvas to a ViewStack.

I am experiencing difficulty in setting the dataProvider for the DataGrids. As
part of the loop, I create a new ArrayCollection to serve as the dataProvider
for the last DataGrid created. But since the loop uses just one ArrayCollection
variable, everytime the loop iterates and a new ArrayCollection is created, the
previously created DataGrids' dataProviders point to the new ArrayCollection,
rather than the one that was created during their iteration. For example, I can
end up with 10 DataGrids (on 10 Canvases) in the ViewStack, and all of their
dataProviders will point to last ArrayCollection created, rather than the
ArrayCollection created in the same iteration of the loop that created that
respective DataGrid.

Is there a way to take a static "snapshot" (for lack of better terms) of an
ArrayCollection in each iteration and use that as the dataProvider for the
newly created DataGrid in that same iteration? Any help or insight is much
appreciated.

//Loop through results, add info to DataGrids and DataGrids to ViewStack
var canvas:Canvas;
var dgataGrid;
var dgArray:ArrayCollection;
var dgCols:Array;
var dgFieldColataGridColumn;
var dgValColataGridColumn;
for each (var result:IdentifyResult in event.identifyResults)
{

dg = new DataGrid;
dg.percentHeight = 100;
dg.percentWidth = 100;
dgCols = dg.columns;
dgFieldCol = new DataGridColumn;
dgValCol = new DataGridColumn;

dg.showHeaders = false;
dg.percentHeight = 100;
dg.percentWidth = 100;
//dg.addEventListener(ListEvent.ITEM_CLICK,onCellP ress);
dgFieldCol.dataField = "field";
dgFieldCol.width = 30;
dgValCol.dataField = "val";
dgValCol.width = 70;

dgCols.push(dgFieldCol);
dgCols.push(dgValCol);
dg.columns = dgCols;

dgArray = new ArrayCollection;
for (var detail:String in result.feature.attributes)
{
dgArray.addItem({field:detail,
val:searchReplace(result.feature.attributes[detail],"Null","")});
}

//set up dgArray for datagrid
dg.dataProvider = dgArray;

//Canvas
canvas = new Canvas;
canvas.percentHeight = 100;
canvas.percentWidth = 100;
canvas.addChild(dg);

//Add DataGrid canvas to ViewStack
idViewStack.addChild(canvas);
}

I think I fixed it. Moving var dgArray:ArrayCollection; above dgArray = new ArrayCollection; seems to have done the trick, and makes sense logically.

Might I suggest that you look at my GroupingFunction calendar example to see
one way that you can have a control (in my case a TileList) that _appears_
like there are a lot of them being switched between with a TabBar, but
what's actually happening is the dataProvider is simply being filtered in a
different way:
