you made callID bindable but don't use it in for binding, but you didn't make callStatus bindable and it needs to be. That's what your warning is about.
Make your timer a class property, rather than a local var. The local var should cease to exist as soon as the method finishes. --- In flexcoders@yahoogroups.com, "Steve Good" <[EMAIL PROTECTED]> wrote: > > I'm trying to make a call to a remote script at regular intervals.
