Ok, good. Now, each item in the first combo box has an XML "location"
node in it. If the location node contains the child nodes necessary to
populate the second combo, then in the "listChangeHandler" do something
similar to what you did in the result handler. You can directly assign
the dataProvider instead of using an instance variable:
var xmlLocation:XML = XML(event.target.selectedItem); //or use the "as"
operator
var xlNames:XMLList = xmlLocation.Name;
cboNames.dataProvider = xmNames;
Do the same in the Names combobox handler to populate the third combo
and the Tree, or whatever.
While this would be my approach, you could also use binding to populate
the comboboxes, something like:
<mx:ComboBox id=" cboNames" dataProvider="{ mybox1.selectedItem.Name}"
../>
Binding is just a little harder to debug, becaue using the handler
function you can trace xmlLocation.toXMLString() to know exactly how to
reference the child nodes.

Subject: [flexcoders] Re: Multiple ComboBox Selection and Tree from XML
I have managed to get this to work, I had to reformat my xml data file.
Now that I have
that working, how would I capture the users selection to populate the
second and and
then the third combobox.
Thank you for the previous post and direction.
