Good to meet you too!

So I copied your code snippet into my ds-test app and edited ds_doit to call
ds_test2() and it seems to be working fine.
function ds_test2() {
try {
var sdcard = navigator.getDeviceStorage("sdcard");
var fname = "testfile";
var file = new Blob( ["Hello, World"], {type: "text/plain"} );
log("About to create file '" + fname + "'");
var request = sdcard.addNamed(file, fname);
request.onsuccess = function()
{
log("File created: " + fname);
alert("File created: " + fname);
}
request.onerror = function(e)
{
log("Unable to create file: " + fname);
log("Reason: " + e.target.error.name);
alert("Unable to create file: " + fname);
}
} catch (e) {
log('ds_test2: caught an error');
log(e);
log(e.stack);
}
}
So I'm, not sure why your onsuccess or onerror isn't being called.
Can you add some dump() statements into your app?
Something like:
dump("About to create file '" + fname + "'\n");
These will show up in the adb logcat output. I'd like to see one just before
calling addNamed and one just after addNamed. At least then we'll know its
being called.
Wrapping the whole thing up in a try/catch block may help to expose errors as
well.
I tried on my unagi and in the emulator. If possible, can you send me your
entire app?
