Flex Question

I am trying to duplicate the functionality in the Adobe Store flex example as a learning tool...

I have an HTTPService set up to pull in data from an xml file.

This data gets displayed in a TileList.

I would like to have additional information slide in from the right in a states panel when the user clicks on an item in the TileList.

This is all working correctly, but I can't seem to pass the necessary data to my states panel...

How do I pass the data, and what data should I pass as the xml file doesn't have unique identifiers per node?

Thanks in advanced.
