We do widget, and as anyone who creates or user widgets knows Adobe Flash-based widget have dominated the social networking and media landscape for many years. With the advent (and growing popularity) of the Facebook Platform, many thought that Flash-based widget would quickly and easily make their way, unfettered, unto Facebook pages, but this has not been the case!

Flash does work on Facebook, but with some limitations. For companies and developers looking to port their Flash-ware to Facebook, here are some important considerations to be aware of:

• Facebook does not support Flash to Javascript communication
• Interaction between Javascript or FBSJ and Flash is prohibited. You’ll have to use flashvars to pass information into your Flash component.
• Facebook does not support Flash links/navigation
• In more technical terms, navigateToUrl and getURL by default do not work in Facebook (See work around)
• You have to embed your Flash in an IFRAME in order to enable navigation to work.
• Facebook and Flash have a problem sharing the same session
• In less technical terms, writing Facebook/Flash applications that recognize a user’s unique activity require some hard work (and experience).
• Flash cannot automatically begin playing on a user’s Facebook profile page
• Flash components cannot automatically begin playing on profile pages, so the fb:swf tag displays a developer-specified place-holder image until the user interacts with the object.
