The Flash is having a great time and is more than happy to call Javascript with ExternalInterface when it wants. But when Javascript wants to chat back… beep beep. “Please leave a message”.

Flash appears to ignore the call, and leaves Javascipt in an error state and needing ice-cream.

To help you avoid that little relationship problem here’s the fix to the problem. Add the following to your code,

System.security.allowDomain(“*.msappspace.com”);
System.security.allowDomain(“*.yourdomain.co.uk”);

Flash’s Sandbox is set to divert all calls by default and blocks any chat. However as soon as you’ve added the allowDomain. Flash shouts, “HELLO!”, and it’s all back on again.

One big happy social networking family.

Good Job rondata, you are the lucky one who patrols the MySpace Developers forum helping for lost coding souls.

Being the social network’s developer’s gate keeper, passing through only the most genuine development question to the MySpace API team. Bit of a tough job to make sure they’re not bombarded with constant questioning about some of the ‘in-progress features’ like, External Interface.

Thought Den felt moved enough by your still ongoing constant plight trawling the forums to say, “proper job”.

It now publishes application activity to the MySpace Friends Feed. For those unfamiliar with the FF, it’s where your friends can keep up to date with all the interesting things you’ve been playing. It’s a great way for your app to gain a bit more traction in the Market place and for others to find it (see below).

Admittedly however, we’re not building an app to pass around cute kittens like our recent NOAH project for the pet factor. Because soon the whole of MySpace will telling their friends about their arguments with aMap!

Here are our findings for any other Flash & MySpace Developers.

- ExternalInterface + SWFObject + iFrame will not work. Do not spend 4 hours refreshing your browser and re-testing. It will not work. There are also no tutorials to sort it out either.

- getURL is just plain dirty. Don’t do it.

The final solution we settled on is, don’t use SwfObject. Just have a plain Object/Embed tag. Then External Interface can talk to all the relevant parties.

Download our MySpace files (put into the Canvas Surface) and see what we’ve done.

Apparently some apps don’t want the MySpace Founder mr Tom Anderson playing their game!

However, not all is rosy. At the first step we’re presented with the choice, “Do you want to develop with OpenSocial or MySpaceID?”.

What? Which one do we choose! Surely like every other social platform, api or online do-hickey you just sign-up, ignore the instructions till it breaks then code like the wind?

It’s not even like the bullet points help you make a decision. Both offer their positives, but not weighted against each others.

To be honest why can’t we just have both? Surely, we could just use OpenSocial as a base and then add on any MySpaceID stuff as it goes?

Nope. One or t’other.
