Okay, I'm trying to figure this out. Things look just like the help
files, but I'm not working. Here's what I got so far....
HTTPService
is this
********************************
<mx:HTTPService
id="rstTree" url=""http://Path/To/XML.aspx">http://Path/To/XML.aspx"
useProxy="false" resultFormat="e4x" result=""
/>
*******************************
I've tried both e4x
and xml as resultFormat.
Script code looks like
this
********************************
import
mx.collections.*;
[Bindable]
public var
myXLC:XMLListCollection;
public function init():void
{
myXLC =
new
XMLListCollection
(rstTree.lastResult.Root);
}
*********************************
I've
got the init function being called at application
creationComplete.
Here's my tree
MXML
********************************
<mx:Tree
id="tvwProjects" width="100%" height="100%"
dataProvider="{myXLC}"
labelField="@label" itemClick="treeClickEvent
(event);"
y="10">
</mx:Tree>
****************************************
Lastly,
here is my xml from the aspx
page.
******************************************
<?xml
version="1.0" encoding="utf-8" ?>
<Root label="Root"
action="">
<menuitem label="2006"
action="">
<menuitem label="2006 07" action="">
<menuitem label="Detail" action="" />
<menuitem label="Rollup" action="" />
<menuitem label="Summary" action="" />
</menuitem>
<menuitem label="2006 08" action="">
<menuitem label="Detail" action="" />
<menuitem label="Rollup" action="" />
<menuitem label="Summary" action="" />
</menuitem>
<menuitem label="2006 09" action="">
<menuitem label="Detail" action="" />
<menuitem label="Rollup" action="" />
<menuitem label="Summary" action="" />
</menuitem>
</menuitem>
</Root>
**********************************
I
know that I'm returning my xml from the HTTPService since I can
show an
alert box with data from it. However, Nothing is showing in
my tree.
Nothing.
Can anyone help?
Thanks,
Aaron

Thanks for the prompt reply. Off to go learn
