Make sure you’re using the
TreeDataProvider methods which means selectedItem.getProperty(“data”),
not .attributes (since that will only work for XML and not when you use an
object graph).

Are you using attributes.data? For example:
<?xml version="1.0"
encoding="iso-8859-1" ?>
<mx:Application xmlns:mx="http://www.macromedia.com/2003/mxml">
<mx:XML id="myXML">
<node
label="FirstNode" data="">
<node label="FirstSubNode"
data="">
</node>
<node
label="SecondNode" data="">
</mx:XML>
<mx:Tree id="myTree"
dataProvider="{myXML}"/>
<mx:TextInput id="myText"/>
<mx:Button label="click me"
click="myText.text=myTree.selectedItem.attributes.data"/>
</mx:Application>
Thanks,
Ted

Subject: [flexcoders] Weird tree issue
I have a tree I'm populating with objects that
mimic my serverside
Group classes. What's happening is that the tree
is getting built, but
the data field of the nodes isn't getting filled.
This method:
var node = treeDP.addTreeNode(group.name, group);
is supposed to create a node with the label of the
group's name, and
the group object itself as the data. Problem is,
while the tree gets
populated, and you can see the nodes with labels,
the actual group
isn't there in the data field. Obviously the group
is getting
instantiated, because the tree nodes have
labels... Any reason why
this shouldn't work?
I'm new to Flex, and AS, but this seems like it
should work.
Below is the code I use to fill my tree...
var treeDP;
public function initGroupTree() {
user =
mx.core.Application.application.user;
var topGroups:Array
= user.organization.onlyTopSuperGroups;
treeDP = new
TreeNode();
for(var i in
topGroups) {
var group:Group = topGroups[i];
var node = treeDP.addTreeNode(group.name, group);
addSubGroupsToTree(node, group);
}
groupTree.dataProvider = treeDP;
}
private function addSubGroupsToTree(node,
group:Group):Void {
var subGroups:Array
= group.subGroups;
for(var i in
subGroups) {
var group:Group = subGroups[i];
var subNode = node.addTreeNode(group.name,
group);
addSubGroupsToTree(subNode, group);
}
}
