Subject Re: AEC in the new release
Date Fri, 26 Apr 2013 06:12:33 GMT
@Maxim
"I'll correct myself in both versions network related parameters can be
passed via injecting it into HTML"
=> What do you mean by that? You want to pass the params as flashvars in
the SWF embed code?
Keep in mind that both SWFs have to read the config values separated.
I am not sure if the SWF8 app can read those flashvars passed in the embed
code.

What about this tab layout thing, has it something to do with the config
parameters or is this a new topic?

Thanks,
Sebastian
