Thank you very much for your support and rapid answer! It is highly appreciated!
I have two extra quick questions about this matter:
a) You said: "You can use a list of online users and call anyone with a click, there is a built-in list in SVC (flash)." <– where can I find this piece of code??!
b) Thanks to your answer I understood that I can send some params to Flash with the "flashvars" variable, but how can I manage those params from the code in flash builder??
I mean, even when I use this in my code: flashvars.userName = "Borja"; and send it to the flash app, when I run the app I appear as "Connected as UNKNOWN". How can I manage the flash code to appear as "Connected as Borja"???
c) Do you have a sample code to create a filter with SVC, for example filters by age or city??
Thank you very much!
