Re: [flexcoders] Component access to dynamic application variable

[Abdul Qabiz]

Why not add another property in dataProvider, which holds the reference of the rootNode. Which you can set/reset from ComboBox selection.So your thumbnails don't have to communicate directly to main application. It would introduce more de-coupling.
So create a variable (rootURL) in main application. When you create dataProvider for TileList, pass this variable to thumbnails via dataProvider.From combo-box selection, you can set the value rootURL to selection.

            I'm currently learning how to utilize components.

In a slideshow app, I have a thumbnail component (image) that is 
rendered by a TileList in the main application.  dataProvider in the 
TileList is being used to supply the path, image name, etc, by sending 
a repeating node of an xml file.  However, I'd like the thumbnail 
component to also be able to read a property of a "selected" parent 
node (via a ComboBox in the main application) of the data its receiving.

Can I make a bound variable in the main application dynmaically 
accessible by the component?

The xml is basically laid out as root(i.e. URL to root).album(i.e. 
folder name).image(i.e. filename), and any time I render an image, I'm 
recollecting the various nodes to produce an absolute URL to the image.

Hope that makes sense...still learning my Flex2 terminology.
