I am using Flex 3 under Flash Player 9.
I have a datagrid that I want to export to Excel. I construct the Excel object (ByteArray) in Actionscript, and now I want to save it using FileReference. However, under FlashPlayer 9, FileReference only has a download method. Can I somehow point this download method to the Excel object?
I think you need to upload your data to your server, and then download it to your client. Look at this example for saving images created in as3 to a client.
OR (this is hackish, but might get done what you need) you can print your data to the debug console.
