1: Flex App talking with a CF Transfer supported backend
2: Flex App talking with a CF Reactor supported backend
3: Flex App pulling in a SWF (Player 4: Flex App pulling in a Captivate video using the SWFLoader and manipulating it (play(), stop(), rewind(), etc…)

Ops, a little too quick there I forgot the suggestions. Going to be all ColdFusion because that’s what I’d know enough to suggest topics on.

1) SES URLs in CF. I seem to see questions about this all the time, and rarely in depth solutions on it.
2) DRY Validation via Ajax. Maybe best practices for validation server side and client side? Seems most examples I read now a days don’t even have any validation.
3) Maybe something a little more easily describable like validating with an ORM. Could be kind of a P2 of the previous one. I know Reactor has a lot of built in validation stuff, but doing validation with Transfer seems to have people confused.

Hope those aren’t too advanced topics, but they are ones I’ve had questions about, and seem to read questions about on CF-Talk repeatedly.

I would love to see some Captivate tutorials on MachII. Mainly the syntax and an intro to the MVC model they use. I have used Fusebox, but I haven’t had the time to learn MachII. I would also like a tutorial on drag and drop functionality in Flex 2. And I think a quick run-through on how to instantiate web services and remote objects using actionscript would be nice. I don’t know if you have used this, but maybe a tutorial on how to integrate google/yahoo into a flex app. I would like to see how to use cflogin effectively in an application.

1. Migrating an app from Flex to Apollo.
2. Making a no-chrome transparent Apollo app.
3. Building an HTML-based Apollo app.
4. Using the JS/Flash gateway.
5. Using States in Flex/Apollo.
6. Using different remoting methods in Flex/Apollo (HTTPService vs RemoteObject, etc)

7. Codebehind –
7a. What a *real* app with Codebehind actually looks like.
7b. Starting from scratch on a Codebehind app. (It’s a bit daunting and easy to lose sight of where to begin.)
7c. Migrating a non-Codebehind app to Codebehind.
