jQuery Grid Plugin - jqGrid

I wrote a smaller version of my grid that illustrates the issues I have, in the process I was able to identify what the problem is so there is no need to post it :).

Now, the problem lies in the loadComplete event--in particular the object that is passed to the handler.   The documentation says that the argument to the loadComplete handler is an XMLHttpRequest object--on the other hand my handler receives one that contains what I expect to find in the xhr.responseText attribute.

Here's my loadComplete handler:

//
function clmt_gridLoadCompleteCallback(request) {
  console.log("TESTER");
  tester.debug.writeObj(request);
}

The writeObj function iterates through all fields and logs them in the firebug console.  The console output looks like this:

So did something change in the argument to the loadComplete event or am I missing something?

TIA
