I would not assign an XMLList to selectedItem. I would extract the XML
node from the XMLList. It is a bug that we don't extract the node
correctly so feel free to file a bug if you want.
categoryComboBox.selectedItem =
myCollection.child('categories').children().(@id == "0")[0];

added to XMLListCollection
Hi,
preventDefault() works fine, thanks a lot Alex!
On to the <mx_internal_uid> mystery node then...
The problem only occurs when I set the selectedItem of the ComboBox but
can't see why that should present this problem?
[artistdata.xml]
<artistdata>
<categories>
<category id="0">
<label>Photographers</label>
</category>
<category id="1">
<label>Stylists</label>
</category>
</categories>
</artistdata>
