The Fattest

I would just listen to the complete event and then enable a download button. You can show a progress bar so the user knows that something is happening. You could even be a little bit more intrusive by popping up a window saying it's encoding is complete and they can download it now.

Okay, but why is it a bad practice?

Thanks for the comments. I'll try to following these suggestions more when doing more tutorials.

I'm not sure that I understand what you're trying to do. But, the javascript and flex have to be on the same page, imagine the flex piece is just another html object. If it hasn't been rendered on the page you don't have access to it. Let me know if I'm off base here.

This isn't strictly possible without extending the datagrid class. What I would say though is that you could build an ArrayCollection made up of objects from both sources. Then you would have to have custom item renderer or label function to display the correct output. This way you wouldn't have to come up with some crazy method of putting two data providers on a datagrid.

try resetting the root password.

also I had issues with my current browser with this. I can't log into any phpmyadmin.

not sure i know what you mean. in a datagrid there are only slightly more itemrenderers than what is visible because it reuses them.

have you ran the debugger on this at all? I would use that to see if creating a new bitmap from the image class is working. Also this will only work with Flex i believe. And lastly it should be creating a BitmapAsset.

I used Flex Builder 3 when creating this tutorial. Not sure what the issue would be without more detail.

This is because the data is being moved around in the array not being updated in any way.
