Ok, my apologies for the irritating vagueness in my explanation:
What I am trying to do is populate 2 grids using an array of value
objects.
Each grid uses various properties of the said value objects, some
different and some the same.
I have a custom render which extends checkbox and thus displays
checkboxes throughout the grids.
I simply want to be able to select ONE checkbox in each grid.
If a check box in one grid is selected and its row is different to the
currently selected check box in the second grid, I will be aiming to
then:
1) Deselect the check box in the second grid.
2) Highlight the row in the second grid to match the newly selected
row in the first grid.
For this to happen I have followed the typical route i.e. have as much
of the handling of the check box selections within the renderer itself
and driven from the data property e.g.
override public function set data(value:Object):void
{
if( value != null )
{
super.data = value;
selected = ( data.column == listData.columnIndex &&
data.row == listData.rowIndex ) ?
data.selected : false;
}
}
override protected function clickHandler(event:MouseEvent):void
{
super.clickHandler(event);
data.selected = selected;
data.row = listData.rowIndex;
data.column = listData.columnIndex;
( listData.owner as CustomGrid ).invalidateList();
IList(DataGrid(owner).dataProvider).itemUpdated(data);
}
btw duplicating an Array using concat() did not work unfortunately as
(adobe doc quote) 'changes are still made to both arrays. So I used
(adobe docs):
private function clone( source:Object ):*
{
var myBA:ByteArray = new ByteArray();
myBA.writeObject( source );
myBA.position = 0;
return( myBA.readObject() );
}

Ok I am a numbnut! Rsolved through 2 seperate arrays, into two
seperate arraycollections!
I must add that if the 2 Array sources are different I then result
in the issue of multiple selections (CheckBox) on row and in
column. Are there any suggestions on how to overcome this?

Are the 2 ArrayCollections using the same source array by any chance?
