RE: [flexcoders] tree display not refreshing
Which version of Flex? Hotfix?
Are any other manipulations preceding this one?
Is the source of the drag the same tree?
Do nodes have the same content?

Hi Alex,
revisited the code this morning and realised I *am* using
the datadescriptor! I'm adding children like this;
for(var i:Number=0; i items.length; i++) {
var insert:XML = node
/;
[EMAIL PROTECTED] =
items[i].TITLE;
[EMAIL PROTECTED] =
items[i].PAGEUUID;
sitemap.dataDescriptor.addChildAt(p, insert, r+i);
}
But I still get the display corruption problem. Any ideas?

I hope to find a way to allow XMLList in Moxie, but no guarantees.

Subject: [flexcoders] tree display not refreshing
When I drag an item into my tree or I delete a node, I'm finding the
tree display is becoming corrupt - it copies some of the branches /
nodes to the bottom of the tree. If I then expand or collapse a node
the display refreshes and fixes itself. I've tried calling
tree.invalidateDisplayList() after the changes but it has no effect -
can anyone point me to how to force this?
cheers,
Toby

Re: [flexcoders] tree display not refreshing
Thanks for that, I'll try switching to manipulating the datadescriptor and see how it goes.
