So I have some code (below) that clones an arrayCollection. It works the first
time through doesn't work the next time through. The objects that are getting
cloned are a custom object called "Node". So my AC has a list of Nodes in it.
The first time the clone returns an Object of type:Object (so pass in Nodes out
comes Objects). The second time through I pass in another list of Nodes and
out comes Nodes. Not what I want.
Why would the code below spit out two different things? I have debugged this
and walked it through and yes I know nodes are going in each time.
private function clone( source:Object ) :*
{
var myBA:ByteArray = new ByteArray();
myBA.writeObject( source );
myBA.position = 0;
return( myBA.readObject() );
}
private function buildTreeCollection(
ac:ArrayCollection ) : void
{
var newAC:ArrayCollection = new
ArrayCollection( clone( ac.source ) );
// add checked to all leaf objects
for each( var o:Object in newAC ){
o.checked = 0;
}
_sortedTreeCollection = new TreeCollection(
newAC );
// add checked to all folder objects
for each ( var ob:Object in
_sortedTreeCollection ) {
ob.checked = 0;
}
trace('');
//myTree.dataProvider = tree;
if( _sortedTreeCollection.length > 0 ) {
typeTree.visible = true;
typeTree.includeInLayout = true;
}
//this.height = Math.max( 150,
typeTree.measureHeightOfItems(0, _sortedTreeCollection.length) + this.height );
}
