Hope that title didn't sound confusing. Essentially, there is a email list with a bunch of links. When you click on a link, it will open the Flex app and go to the appropriate page with the company info. I essentially add header info and use the ExternalInterface.call to read the URL.
Now the problem is that there are a BUNCH of links. So if I like on the first link, cool it works. If I click on the 2nd link, it will open a new window (and Flex app). This isn't user friendly. The Flex App uses a tabbed interface, so it would be neat if I could add another company info tab on the spot.
So I need to somehow send a message to my Flex App to create a new tab from a link clicked on an html email. I think the steps would be (if possible)
1) Find out if the Flex App is already open
2) Open a new tab based on the URL.
Is there any way of accomplishing this with the sandbox and all? Hope I made things clear.
