Cheese and Crackers!
Ok, I see what to do now. In the past the callback handler would toss me the
query I requested and then I would continue processing. Now all I need to do it
seems is:
var uInfo = getUserInfo(id)
...continue processing
function getUserInfo(id)
{
foo.setSyncMode();
return foo.method1(); }
So I suppose what I had backwards was the callback is used to allow
asynchronous processing but if I want synchronous I don't bother with it.

If you run things synchronously, there is no callback. Does that answer your
question? You'd just set sync mode and call your methods in sequence.

Which is what sync mode is for.

In the code case, I send my request, via getUser(id), which calls the function
that fires the CFC and then the return is captured. Back when I was using
CFCAjax it was waiting for the return, now that I moved to CFAJAXPROXY it is
not waiting, no matter what I set (setAsyncMode or setSyncMode)
and to quote the site:
setSyncMode - Sets the mode of network operation to be synchronized. This means
the page will wait until the server responds with the result
</blockquote>
Well first of all, don't compare anything you're doing now with CFCAjax.
But as I said before, using sync mode and using a callback method are mutually
exclusive. Check the examples here:
http://www.openbd.org/manual/?/tag/CFAJAXPROXY
If you want to call a method, get the response, then call another method, you'd
just do:
foo.setSyncMode();
foo.method1();
foo.method2();
In that case method1 and method2 would run in sequence since it wouldn't
proceed with method2 until method1 finished.
You'd only use a callback method if you wanted the page to NOT wait for the
response from the server, and the callback method would be called *whenever the
response comes* as opposed to your page waiting for a response. --
