To simplify, I removed all of my other widgets. 

I'm not exactly sure what all I'm seeing, but here is what I think is the relevant part of the trace output:

I see that the crossdomain.xml file gets accessed, but then nothing else happens -- the widget times out after 30 seconds and the whole process starts over.

Do you see anything of use here?

Thanks,

JVC -- yeah, I was fiddling with it, including removing it for a few minutes.  You must have first hit the site during that small window.

I'm now completely at a loss.  The widget shows up with valid data it in in the "Edit Channel" page on the chumby website -- if I select my widget from the list it previews WITH WEATHER DATA IN THE DISPLAY.  Once I actually add it to the channel, though, neither the virtual chumby nor the real one show any data.

My .fla file looks like this -- it's really nothing more than a pared-down version of the rss reader example:

/*
 * Get weather from local neighborhood weather station and display on the Chumby
 */
 
g_rssURL = 'http://www.thehargroves.com/weather/currentwx.php'; // Get current wx readings

delay = 60000;  // one minute between data refreshes

    var n = this.firstChild;
    while (n) {
        if (n.nodeName==s) {
            a.push(n);
        }
        n = n.nextSibling;
    }
    return a;
}
//

//
Object.prototype.firstChildOfType = function(s) {
    var n = this.firstChild;
    while (n) {
        if (n.nodeName==s) {
            return n;
        }
        n = n.nextSibling;
    }
    return null;
}
//

    var n = this.firstChild;

        }

    return null;
}

then = 0; // long, long ago....
this.onEnterFrame = function () {
    now = (new Date()).getTime(); // get current time in ms from the epoch
    if (now-then>delay) { // enough time elapsed since weather reading?
        loadRSS();
        then = now; // and reset the last load time
    }

        Windspeed.text = "Calm";
    } else {

}

This is driving me crazy.

Great thought!  The chumby is going through a Netgear WiFi router on the inside of my network (it's really just acting as wireless bridge) and then through a Cisco 2600.  I'll have a look at router logs as well as my Apache logs.  It helps a LOT to know that the problem isn't with the .fla file or the crossdomain.xml.

Any idea why the "widget preview" in the channel editor works, while the virtual and the real thing don't work?

I very much appreciate the help!

-M.

Yes - the chumby *should* use your ISP's DNS to resolve your domain name to your public IP.  You can verify this by doing an nslookup on the chumby's console:

nslookup www.thehargroves.com

I get 66.227.28.114 for your IP.  I can fetch a header from your server:

chumby:/mnt/usb# curl -I http://www.thehargroves.com/crossdomain.xml
HTTP/1.1 200 OK
Date: Sun, 30 Dec 2007 08:20:37 GMT

ETag: "18d0035-d9-df70d640"
Accept-Ranges: bytes
Content-Length: 217
Content-Type: text/xml

chumby:/mnt/usb#

I'm curious what your chumby does if you try this - if it hangs, then it's very likely your router at fault.

Just out of curiosity, what domain does the chumby appear to be coming from when it attempts a cross-domain access?  Is it chumby.com?  Can I narrow my crossdomain.xml access to just <allow-access-from domain="*.chumby.com"> and expect all my widgets that access my server to work?
