Hi,

the ExternalInterface calls are used by a flash application to communicate with the javascript that's in the page where the flash movie is.

Our flex library does not require such method, so you should understand what is used for in your application keeping in mind that this is completely unrelated with Lightstreamer itself.

On the other hand note that we also have a flash library that leverages our JavaScript library to get a connection to the Lightstreamer server using the ExternalInterface. I think that this library cannot be used in an AIR application.

In any case neither of the two libraries contain a public subscribeItems method, so you should first clarify which library you're using.

Flash Client Library: http://www.lightstreamer.com/docs/cl...api/index.html

Please note that the Flex Client Library is not compatible with the standard Allegro and Moderato versions of the server.
