Trouble with Twitter app

[Larry Q]

Hi everyone,

I'm using Google Chrome to test some of the Sencha demos. Right now I'm playing with the twitter application, as found here:

http://dev.sencha.com/deploy/touch/examples/twitter

But am doing it on my local box, and am receiving an error for my trouble. The problem is in the call in TwitterProxy.js:



buildRequest: function(operation) {
var request = Ext.data.TwitterProxy.superclass.buildRequest.apply(this, arguments),




That line blows up in sencha-touch-debug.js, around line 8930. Here's the snippet:


buildUrl: function(request) {
var url = Ext.data.ScriptTagProxy.superclass.buildUrl.call(this, request),
params = Ext.apply({}, request.params),
filters = params.filters,
filter, i;

delete params.filters;

if (this.autoAppendParams) {
url = Ext.urlAppend(url, Ext.urlEncode(params));
}

if (filters.length) {


The problem is filters.length is null. Thus the blowup.

I'm not having a problem on the dev.sencha.com site, using this demo. I downloaded the API about a month ago. Any ideas what might be going on? Most of the demos work fine on my laptop.
