[flexcoders] assigning a value to a model value object

[Webdevotion]

Hello,

I want to assign a value from my libraryview's datagrid to
a TrackVO in my modelLocator.

model.currentTrack = gridlist.selectedItem as TrackVO;

However, this will not work, currentTrack is null.
When I do Alert.show( gridlist.selectedItem.file ) it shows
me the correct output.

What is the correct way to put the gridlist.selectedItem data
in a value object of my modellocator, so I can keep my data
wellformed.

tnx.
