I was recently developing a Flex application that needed to be integrated into an existing e-Commerce site. As part of the integration, I needed to communicate information between the Flex application and the containing HTML / JavaScript page. I don’t believe I’ve ever seen a web site that put together all of the various scenarios that I wanted in one place. So, I put together an application that contains small examples of each scenario that I was interested in. I thought it might be helpful to post these simple examples for others.
