I try to reload a Web page using (JavaXPCOM):
nsIWebBrowser webBrowser = (nsIWebBrowser) browser
.getWebBrowser();
nsIWebNavigation webNavigation = (nsIWebNavigation) webBrowser.queryInterface(nsIWebNavigation.NS_IWEBNAVIGATION_IID);
try {
nsISHistory sessionHistory = webNavigation.getSessionHistory();
if (sessionHistory != null) {
webNavigation = (nsIWebNavigation) sessionHistory.queryInterface(nsIWebNavigation.NS_IWEBNAVIGATION_IID);
}
} catch (XPCOMException e) {
}
webNavigation.reload(nsIWebNavigation.LOAD_FLAGS_NONE);
But reload doesn't happen at all. I tried force it by using the following flags, but page doesn't refresh as well:
nsIWebNavigation.LOAD_FLAGS_BYPASS_PROXY|nsIWebNavigation.LOAD_FLAGS_BYPASS_CACHE
Anyone knows what can be the reason for that?
Thanks!
Did you try checking Error Console for syntax errors? You seem to be trying to use C++ type casts in JavaScript. That cannot work. Assuming that browser is a <browser> element, this should work:
browser.reload();
Or:
browser.reloadWithFlags(Components.interfaces.nsIWebNavigation.LOAD_FLAGS_BYPASS_PROXY|Components.interfaces.nsIWebNavigation.LOAD_FLAGS_BYPASS_CACHE);
See https://developer.mozilla.org/en/XUL/browser for documentation on the <browser> element.
Edit: Given that this is apparently using JavaXPCOM the code seems to be correct with the exception that the entire try .. catch block should be removed. The only flag should be LOAD_FLAGS_BYPASS_CACHE to make sure you don't get a cached response.

I try to handle a Summernote Keyup event with this:
myEditor.addSummernoteKeyUpHandler(new SummernoteKeyUpHandler() {
#Override
public void onSummernoteKeyUp(final SummernoteKeyUpEvent event) {
// TODO Auto-generated method stub
log.fine("hello");
}
});
I get a UmbrellaException which is IMHO a class cast exception.
This is the call stack
I identified the following spot where te cast failes:
#HasNoSideEffects
static native boolean canCast(Object src, JavaScriptObject dstId) /*-{
if (#com.google.gwt.lang.Cast::instanceOfString(*)(src)) {
return !!#com.google.gwt.lang.Cast::stringCastMap[dstId];
} else if (src.#java.lang.Object::castableTypeMap) {
return !!src.#java.lang.Object::castableTypeMap[dstId]; //<-- this returns false!!!
} else if (#com.google.gwt.lang.Cast::instanceOfDouble(*)(src)) {
return !!#com.google.gwt.lang.Cast::doubleCastMap[dstId];
} else if (#com.google.gwt.lang.Cast::instanceOfBoolean(*)(src)) {
return !!#com.google.gwt.lang.Cast::booleanCastMap[dstId];
}
return false;
}-*/;
dstId contains:
Any help greatly appreciated!
I tested this with a small demo which actually works. But in my large application, I get this exception and I don't see why.
Do you have any idea whats wrong here?
Best regards

As Andrei suggested I set the style to DETAILED. I use Eclipse as a development environment. I decided to clean build the system (which I had done before). Now the problem has simply vanished !! Furthermore, I use SDBG (see: https://sdbg.github.io/) to debug my GWT application. This works pretty well (even without -style DETAILED). Now the very very strange thing remains. I can set breakpoints for my application and they all work well, except setting a breakpoint within the event handling method. I use a logger to print some text to the console, so I see that the event handler for summernote is actually called but the debugger will not stop. I checked whether the breakpoint is listed in the tab "Breakpoints" and it is and it is checked. I don't get it. Perhaps I have to rebuild all again.
But to keep long things short:
The solution to the problem is probably to really issue a clean build and then hope for the best.
UPDATE2: I revisited this issue and have solved the problem by carefully following the doco linked below. But first, for those who are struggling with this, you are in good company. There are so many versions of the doco from Google it is confusing! Do you include platform.js or client.js in your html? Do you load gapi.auth or gapi.auth2? Do you use gapi.auth2.render or gapi.auth.authorize, or gapi.auth2.init, and so on.
The way that returns an access_token (as of this article date) is linked below. I managed to get this working by carefully following the guide and reference using platform.js. Other libraries are then dynamically loaded such as client.js using gapi.load('drive', callback).

==== ORIGINAL ISSUE FOR PROSPERITY ====
UPDATE 1:
I've updated the code sample to do a recursive search of the googleUser object. At least this shouldn't break in a subsequent library.
Below is a code snippet to handle an issue where the access_token in the Google gapi.auth2.AuthResponse object is not at the top level... it is hidden :( in the depths of the object!
So it is retrievable, but not at the top level!!?? I've noticed it seems to be a timing issue... once the application is running for a while on subsequent checks, it does contain the access token at the top level!!
var authResponse = _.googleUser.getAuthResponse();
_.id_token = authResponse.id_token; // Always exists
// access_token should also be a param of authResponse
if (authResponse.access_token) {
debug("Worked this time?");
_.access_token = authResponse.access_token;
} else {
// !!! Internal object access !!!
debug("Attempt to get access token from base object.");
_.access_token = _.objRecursiveSearch("access_token", _.googleUser);
if (_.access_token) {
debug("Access token wasn't on authResponse but was on the base object, WTF?");
} else {
debug("Unable to retrieve access token.");
return false;
}
}
_.objRecursiveSearch = function(_for, _in) {
var r;
for (var p in _in) {
if (p === _for) {
return _in[p];
}
if (typeof _in[p] === 'object') {
if ((r = _.objRecursiveSearch(_for, _in[p])) !== null) {
return r;
}
}
}
return null;
}
I'm guessing getAuthResponse somehow provides a callback once it is ready, but I can't see where in the API.

I know this question is fairly old, but it appears first when googling for ".getAuthResponse() doesn't have access_token," which is how I got here.
So for those of you in 2016 (and maybe later) here's what I have found out
There's a secret argument on .getAuthResponse, not documented anywhere I have found. If you would run the following in your app
console.log(gapi.auth2.getAuthInstance().currentUser.get().getAuthResponse);
You would see that you get the following (copy/pasted from my console)
function (a){if(a)return this.hg;a=.HE;var c=.rf(this.hg);!a.Ph||a.dL||a.Lg||(delete c.access_token,delete c.scope);return c}
This shows that the .getAuthResponse() function looks for an argument, and as far as I can tell doesn't even check its value -- it simply checks if it is there and then returns the whole object. Without that function, the rest of the code runs and we can see very clearly it is deleting two keys: access_token and scope.
Now, if we call this function with and without the argument, we can check the difference in the output. (note: I used JSON.stringify because trying to copy/paste the object from my browser console was causing me some issues).
console.log(JSON.stringify(gapi.auth2.getAuthInstance().currentUser.get().getAuthResponse()));
console.log(JSON.stringify(gapi.auth2.getAuthInstance().currentUser.get().getAuthResponse(true)));
getAuthResponse() object
{
"token_type":"Bearer",
"login_hint":"<Huge mess of letters>",
"expires_in":2112,
"id_token":"<insert your ridiculously long string here>",...}
getAuthResponse(true) object
{
"token_type":"Bearer",
"access_token":"<an actual access token goes here>",
"scope":"<whatever scopes you have authorized>",
"login_hint":"<another mess of letters>",
"expires_in":2112,
"id_token":"<Insert your ridiculously long string here>",
...}
Figured out the fix for this. Turns out that if we don't provide the login scope config in gapi.auth2.init it doesn't return access_token in getAuthResponse. Please call gapi.auth2.init as given below and access_token will be present.
gapi.auth2.init({
client_id: <googleClientID>,
'scope': 'https://www.googleapis.com/auth/plus.login'
})
I have an observer on "http-on-modify-request" and I need to get the DOMWindow that request is associated with.
The following code was taken from AdBlock Plus and is based on this article.
function getRequestWindow(/**nsIChannel*/ channel) /**nsIDOMWindow*/
{
try
{
if (channel.notificationCallbacks)
return channel.notificationCallbacks.getInterface(Ci.nsILoadContext).associatedWindow;
} catch(e) {}
try
{
if (channel.loadGroup && channel.loadGroup.notificationCallbacks)
return channel.loadGroup.notificationCallbacks.getInterface(Ci.nsILoadContext).associatedWindow;
} catch(e) {}
return null;
}
However, this code is no longer working on multiprocess Firefox (v36+, right now on Firefox Nightly).
Any ideas?
I haven't tried that myself, so take with a grain of salt:
Instead of getting the nsIDOMWindow itself from the channel you can get the innerWindowId from the nsIChannel.loadInfo. The window id can then be resolved inside a frame script by QueryInterfaceing to nsIDOMWindowUtils.
To talk to content, the recommended path for this sort of use case is probably Frame Scripts, see this documentation on MDN for more.
I have created an automated test that logs a user in to a site and performs certain operations. The test first runs in Firefox, Chrome and then IE. It runs perfectly in Firefox, closes the browser and then performs the test in Chrome and again closes the browser. When the exact same test opens the URL in IE it says it is unable to locate the element 'UserName' for the login process.
I have a wait function which I tried to extend in case it was a problem with the page rendering but this didn't work. When using the dev tools and searching for the element it finds it no problem so I am confused as to how it fails in the test.
Does anyone know what could cause this in IE?
The HTML for the text field looks like this...
The Selenium code that works in FF and Chrome but not IE is:
private Results _Test_Login(IWebDriver driver)
{
Results rt;
driver.Navigate().GoToUrl("MyURL");
driver.FindElement(By.Id("UserName")).Click();
TextboxOperation type = new TextboxOperation("UserName", driver, "Success", EnumSearchType.ById);
OperationExecutor.PerformOperations(type);
rt = new Results(driver.Url, driver.PageSource, "Existing Users");
return rt;
}
[TestMethod]
public void Test_Login()
{
List<IWebDriver> drivers = new List<IWebDriver>() { firefoxDriver, chromeDriver, ieDriver };
foreach (IWebDriver driver in drivers)
{
Results results = _Test_Login(driver);
if (results.Exception != null)
{
throw results.Exception;
}
Assert.IsFalse(results.ErrorState);
}
}
Sometimes you need to put a pause just before trying to locate an element because the page or frame is not yet ready. Or, if you don't want to have a pause, you can use a time-limited while loop wrapping a try-catch that handles error conditions and retries the find if it fails.)
The test can be found here. I would like to be able to pass my plugin a new option string of 'false' and have my timer stop. http://www.jsfiddle.net/j78nk/2/
There is no element with the class gallery2 on that page, so pressing the button won't do anything.
Also, you are not checking the set options, only the defaults. And you return right away, before you do anything:
if (!defaults.running) {
return;
console.log('timer is inactive');
}
That code needs to be:
if (!options.running) {
console.log('timer is inactive');
return;
}
