There are several places in the docs which should be updated then. I'll
note them here, then put comments in the livedocs.
In "Using hierarchical data providers":
"While you can use an XML object directly as a dataProvider to a
hierarchical data control, you should first convert it to a collection
if the object changes dynamically. Doing so will ensure that the
component represents the changes to the collection."
In "Creating a Tree control":
"As with all data provider controls, if the data provider contents can
change as a result of actions outside the Tree, wrap the data source in
a collection, such as an ArrayCollection or XMLListCollection object,
and specify the collection in the Tree control's dataProvider property."
And there is another place I can't find right now, that says something
like:
"XML, by default will not cause a control to update"

Subject: [flexcoders] Re: F2b3: e4x XML object as Tree dataprovider, how
to refresh tree display?
Post beta3, changes to XML will automatically get updated in the Tree
control. And you won't be required to go through XMLListCollection
but you can simply make changes to the XML model itself, e.g. delete,
+, appendChild, etc.
You're seeing a bug in the b3 Tree where the collection events aren't
being handled properly.
