Snow Leopard Dashcode - dynamic data source for search via web API

Question

I'm making a dual product dashcode project, for safari and mobile safari. I have a dataSource that is a web API that takes a couple of variables to return results in JSON format. When the safari product launches, it's set up to ping the API with a set of parameters and populate an itemsList in my left sidebar. I have a search field above that itemsList. Now I can get the search field to:
1. take the contents of the search field and construct a new URL from it.
2. go out and ask for results from pinging the API via an XMLHTTPRequest.
3. eval the contents and be ready to put it into the itemsList...
the questions I have are:
1. Where do I put the evaluated JSON results? DC.dataModel.dataSource.content ?
2. What's the trigger to get my itemsList to reload the data?
Here's the relevant search handler function code:
function mySearchHandler(event)
// Values you provide
var searchFieldValue = document.getElementById("search"); // replace with ID of search field
// Search field code
searchFieldValue = searchFieldValue.value;
// Values you provide
// The feed to fetch
var feedURL = "http://myurl.com/api.php?searchfortext="+ searchFieldValue + "&resultformat=json";
var onloadHandler = function() { xmlLoaded(xmlRequest); }; // The function to call when the feed is loaded; currently calls the XMLHttpRequest load snippet
// XMLHttpRequest setup code
var xmlRequest = new XMLHttpRequest();
xmlRequest.onload = onloadHandler;
xmlRequest.open("GET", feedURL);
xmlRequest.setRequestHeader("Cache-Control", "no-cache");
xmlRequest.send(null);
and then in my xmlLoaded function, I figured it would be something like this:
function xmlLoaded(xmlRequest)
if (xmlRequest.status == 200) {
//' xmlRequest.responseText has what I want in it. Where do I put it? I thought it was here:
DC.dataModel.dataSource.content = eval(xmlRequest.responseText);
// or was it here? Neither of these seem to work.
// DC.dataModel.itemsList.setContent(DC.dataModel.dataSource.content);
// Then what, get the itemsList.object and tell it to reload itself... ? Doesn't work for me. :-
document.getElementById("itemsList").object.reloadData();
else {
alert("Error fetching data: HTTP status " + xmlRequest.status);
But... this doesn't work. I can evaluate DC.dataModel.dataSource.content and I can see my new search results sitting there. But I can't get my itemsList to refresh the display and load up what the web API gave it. How does this work in snow leopard dashcode?

CrashPlan is a beast prone to ruining any other purpose on the server. I'd highly recommend moving it to it's own dedicated machine, like a mac mini. When I use CrashPlan that's my preference.
You can find more information about mds by looking at it's man page, mds(8) and the man pages of it's related utility mdutil(1). Your mds database is likely corrupt. You have a few options. Wipe and reindex your metadata stores and/or turn indexing off on volumes that you don't need it.
