Jesse MacFadyen commented on CB-964:
------------------------------------

Test case :
{code}
window.onerror = function (msg, fn, ln) {
    console.log("error : " + msg + " file: " + fn + "ln:" + ln);
};
window.addEventListener("callbackerror", function (err) {
    console.log("got a callback error ! " + err.message);
});
        
window.requestFileSystem(LocalFileSystem.TEMPORARY,0,
    function (res) {
        throw new Error("WTF success");
    },
    function (err) {
        throw new Error("WTF error");
    }
);

>             Project: Apache Cordova
>          Issue Type: Improvement
>          Components: CordovaJS
>    Affects Versions: 1.9.0

> Error in success callback should generate a document event. This is important when loading,
since for example an error occurs while deviceready. There is a try-catch statement in the
CordovaJS, hence window.onerror() is not detecting the error.
> For example, Sencha Touch 2 fails to load because of localstorage corruption while loading,
an the app crashes. A possible fix in this case is to clear the local storage and to window.location.reload();
> it is very east to fix this one - just add:
> fireDocumentEvent("CDVSuccessCallbackError");
