x6.json.executeAsync
By default Andromeda sends JSON requests synchronously,
which is more appropriate for business database applications
than asynchronous requests.
There are however some times when you do not want the user
to wait, and so you can make asynchronous calls.
Andromeda does not make use of response handlers, see the
above section on x6.json for more details.
this.executeAsync = function() {
this.execute(true,true);
