Issue in using combobox in flashlite application

[mukesh.gupta]

Hi,
I created the flash(mobile) application , created the new layer with
other layers, dragged the combobox on the design. On TestMovie,
combox appears in the design.

Now in ActionFrame I created the dataprovider instance and an array
with 10 items in the array.
Used the for loop and insert the item in dataprovider from the array
and assigned dataprovider to the combobox.
On TestMovie, I got the following error :
The class or interface 'fl.data.DataProvider' could not be loaded.

Then I wrote the statement "import fl.data.DataProvider" at the top of
Action-Frame.Still on TestMovie, giving me the same error.

How to solve this?
