Hi Deepa,
I'm using the DefualtDataDescriptor as the super class but, I have a
midified version of the setToggled() method.
var field:String = tree.toggledField;
if (node is XML ||
node is XMLList)
{
try
{
if (field.search("@") != -1)
{
node[field] = value;
}
else
{
node["@" + field] = value;
}
//trace("NODE", [EMAIL PROTECTED], field)
}
catch (e:TypeError)
{
//trace(e)
}
}
It's actually this line;
node[field] = value;
that goes to the XMLChangeWatcher.
Once it is in the change watcher and update is called and then a reset is
called.
In the change watcher, it hits the attributeAdded.
path;
initializeXMLForNotification()
IXMLNotifiable(notifiable).xmlNotification(currentTarget, ty, tar, value,
detail);
currentTarget : the node the descriptor changed
ty attributeAdded
tar node
value toggled
detail true
xmlNotification()
case 'attributeAdded'
itemUpdated()
itemUpdateHandler(event);
listChangeHandler()
You know, as I am writting this I am running the debugger. I can see the
update everywhere. It goes on forever. Then I step throught to the end and
it's the last thing that happens. I can't find it right now but, right at
the end it resets the tree.
It definitly is being spawned by this
-> node[field] = value;
Peace, Mike

Hi Michael –
Whenever an item is updated in the model, the Tree should receive an
UPDATE type of collectionChange event, not a RESET. Have/Can you narrow down
which call is causing the RESET to be emitted? My attempts to add an
attribute to a data item in the model via the descriptor or through the
model itself always produce an UPDATE type of collectionChange event.
Incidentally, we use the setToggled() method in DefaultDataDescriptor for
menu-based controls. I'm assuming you're adding a similarly named attribute
to your Tree's model to indicate to the CheckBox whether it should be
selected or not?

Hi,
I have a little problem here.
I have a check box tree that works fine most of the time. I have run into
a bug that I didn't have before.
I have debugged it using the debugger and found the 'problem'. When you
assign an XML dataProvider, I use a dataDescriptor that sets an @toggled
attribute on the model.
The problem is, the XMLChangeNotifier sends an attributeChanged event and
eventually down the line, the Tree gets a CollectionChange event that is a
'reset' right at the end of a toggle on the check box.
The problem is, if the Tree is scrolled, it resets the scroll position to
0 every time becasue of the reset event.
I have tried doing a hac blobk during toggle select but, it ends up
messing the view of the Tree.
How can I fix this?
Peace, Mike
