COPY operations arent supported in the Tree by default because the
framework cant guarantee deep copies of your objects. You'll need to
implement your own COPY logic in the DND methods (MOVE can stay the
same) including your own object copy.

Use the @ symbol for e4x attributes.
var attributeValue:* = [EMAIL PROTECTED]
Note that if the attribute doesnt exist then you'll get back an empty

The Flex 2 Tree control was designed with this scenario in mind. I'd
take a look at the ITreeDataDescriptor, its default impl, and the
various examples on this list and in the FDS samples.war.
Basically, you'll pass your data to the Tree as it is. Then you'll
implement your own ITreeDataDesc
I took a look and updateDisplayList is getting called due to the mouse
events, tree events, and scrolling. It seems correct but I'll verify
they are all supposed to be there.
Assuming for the moment that they are necessary, you'll probably want
to keep your drawing in UDL and add a flag in UD
I'm not exactly sure what the question is, but it seems you're asking
if changes to data pulled from the Tree will be seen in the
original data structure?
If that's what you mean, then you don't need binding, the Tree control
already uses (and returns) your data by reference. If you get a da
To replace the text of a node you can use replace();
var myXML:XML = blah;
trace("myXML:", myXML.toXMLString());
myXML.replace(0, "new node text");
trace("myXML:", myXML.toXMLString());
Output:
myXML: blah
myXML: new node text

Post beta3, changes to XML will automatically get updated in the Tree

but you can simply make changes to the XML model itself, e.g. delete,

In general, you'd look at your components and their relationship with

That's correct, dragMoveEnabled is true by default. The reason is that

I'll doublecheck the docs. Thanks for posting the error.

Does the process have permission to read/write to that location?
You might try creating the empty file (default name is flashlog.txt),
and then reverifying. You might also try explicitly setting the
filename param to something linux friendly like
TraceOutputFileName=/var/log/flash/log

There's certainly a bug in here, but you can try replacing the
appendChild call:

with:
selectedNode.insertChildBefore(null, newItem);
Also, I changed selectedNode to type XML from Object.

In getChildren you'd run the service calls and return the appropriate

There's a temporarily open bug in Tree that is causing items to be
inserted without the corresponding remove. This appears to be a copy,
but its really a bug in move.
For now you can delete or copy your objects by implementing your own
drag methods. dragStart and dragComplete should do the trick
It's probably a bug if isBranch is ignored in some cases and not others.
Also, there's no need to use a custom renderer in this case. The
IDataDescriptor interface allows custom implementations of the

relationships between parents a
Hi Jonas,
The Tree control has a few new attributes and classes to take advantage
of AS3, e4x and to be generally consistent with other components like
List. For the same reasons, we've also removed the ITreeDataProvider
interface and its related classes.
Things to keep in mind when using the ne
Hi Gunnar,The Tree control no longer provides fine grained access to the nodes and node attributes of the underlying data model, instead you can use your own contract with the data directly. So if you want to read or change your data, you would do so on that data without going through the Tree
