Re: Development Mode will not be supported in Firefox 27+
I'm using IntelliJ...I'd like to hear if/how IntelliJ can do this too. With the released IntelliJ 14 things are a bit easier. - Create a new GWT run configuration and select User Super Dev Mode and at the bottom with JavaScript debugger. - IntelliJ will automatically generate a JavaScript debugger run configuration. Open that run configuration and you should see your GWT project directory tree. In that tree navigate to your source folder (src or src/main/java) and double click on the Remote URL column next to it. The remote URL is where IntelliJ will download source map files from so you should paste in something like http://127.0.0.1:9876/sourcemaps/module-name. Now launch the GWT SDM run configuration which should also automatically launch the JavaScript Debug configuration. Chrome should now tell you that IntelliJ is debugging your site (you may need to install the LiveEdit Chrome extension) and you should be able to set break points in your Java code and step through the code from within IntelliJ. Sometimes when you hit a break point the source map file isn't ready yet in IntelliJ (seems like a timing problem) and you see the pure JavaScript. But once you do the first step over IntelliJ should switch to the Java source by using source map information. Overall it works pretty well. But keep in mind that fields and expressions in conditional break points are still all JavaScript. You are not debugging Java! -- J. -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Exception thrown by XMLHttpRequest
Hi All, I am developing an application using GWT in version 2.5.1. Few days ago we found in our logs that there is a huge amount of exceptions (few per second!!!) that look as follows: Nov 5, 2014 6:00:45 PM com.google.gwt.logging.server.

To stop that, it was not enough to close the browser, but also to kill process from the Task Manager. But I am not sure if it couldn't be triggered also by another browser. I also found this comment in the com.google.gwt.http.client.Request class, method cancel(): /* * There is a strange race condition that occurs on Mozilla when you cancel * a request while the response is coming in. It appears that in some cases * the onreadystatechange handler is still called after the handler function * has been deleted and during the call to XmlHttpRequest.abort(). So we * null the xmlHttpRequest here and that will prevent the * fireOnResponseReceived method from calling the callback function. * * Setting the onreadystatechange handler to null gives us the correct * behavior in Mozilla but crashes IE. That is why we have chosen to fixed * this in Java by nulling out our reference to the XmlHttpRequest object. */ I don't have knowledge about how requests are working but I am wondering if new releases of Mozilla Firefox didn't cause that above solution doesn't work in some cases. Do you have an idea what is the source of the problem and could you please give us any advice how to solve this issue or maybe some workaround how to deal with it?

Re: GWT Cross Site Iframe Linker and Script Tags
Well, it was a Code Splitting problem. Both SuperDevMode and DevMode works fine with the new linker. Le mercredi 5 novembre 2014 23:21:22 UTC+1, Etienne Lacazedieu a écrit : Hi, I'm preparing a big switch (GWT2.3 to 2.6.1, which may change to 2.7.0 depening on the final release date), and I'm having trouble with the xsiframe linker.. I have no problems with adding script tags in the HTML file. Actually, I wrote a linker (a subclass of CrossSiteIframeLinker), which outputs the list of JS files to a properties file. On the server side, a class reads this file to add script tags (we use JSP). My problem is that we have a rather complex integration process, with several GWT applications on the same page. - a Container app, which creates Desktop-like UI, and exposes some JS native API to interact with other apps. - several Functional apps, each one containing one or more functional modules. Each functional module description is injected to the container app, which creates a launcher command. Invoking the command (done in the container app) triggers the creation of the functional module UI (done in the functional app). When this function returns, the container grabs the new DOM element and creates a Window UI around it. My problem with the XSI linker is that I cannot get it to work as it did before.. In my sample deployment, the container is called SampleGWTContainer, and the functional app is called SampleApplication. I have the following error in the console : $wnd.SampleApplication.runAsyncCallback2 is not a function The odd thing is that when I start SuperDevMode, and recompile SampleApplication, it works. If I recompile SampleGWTContainer, I have the same error. I still have to try to remove the split point, to make know if it is a Linker or a Code Splitting related problem.. Any idea that might help me out?

Also not being able to use script in the module xml breaks encapsulation of modules, as I know have to include *all* scripts from *all* libraries in *my* host page (for me that's implementation details that I don't care about) . There's ScriptInjector http://google-web-toolkit.googlecode.com/svn/javadoc/latest/com/google/gwt/core/client/ScriptInjector.html to encapsulate loading within the module's code. I know superdevmode is still experimental and seriously hope that this will be fixed. In the meantime does anyone have an idea how to work around this? Besides manually patching a 3rd party library... In your module that enables the SuperDevMode hooks, add the failIfScriptTag configuration property and add an entry-point that uses ScriptInjector to load the 3rd-party scripts. The 2 entry points (from your app, inherited GWT module, and from the SuperDevMode-specific module) will both be executed; beware though that onModuleLoad will be called *before* the scripts are loaded, so your code that depends on them has to wait a bit… There are a couple ways to workaround this if really needed (but it's a bit more invasive for your app; that being said, xsiframe is the future, and might becomes the default at some point, so better be prepared –and update your 3rd-party libs–) -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Google 4.4 latest plugin update for Eclipse.
I've just updated to the latest version of the plugin for Eclipse and noticed two things: *A*) There is now a Run as SDM for GWT enabled projects. It seems to work fine with source code pulled from other projects via linked folders which is nice. Because of the way our Servlet is configured, it doesn't work inside of Jetty. So we just tell Eclipse to start the superdevmode followed up by running it on Tomcat and sdm is working fine. *B*) It still only has an option for GWT 2.6.0 SDK as part of the downloadable SDKs? Is this intentional? I was expecting 2.6.1 as being an option under the SDK list. -Mike -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

[gwt-contrib] Re: JSInterop assign a function/callback to a property
@Kay-Uwe Janssen
I am doing support IndexedDB with JsInterop to do some tests, and also I
have to assign a function:
interface IDBRequest : EventTarget { ...* attribute EventHandler
onsuccess
https://dvcs.w3.org/hg/IndexedDB/raw-file/tip/Overview.html#widl-IDBRequest-onsuccess;*
attribute EventHandler onerror
https://dvcs.w3.org/hg/IndexedDB/raw-file/tip/Overview.html#widl-IDBRequest-onerror;
};
Use the request in JS:
request.onsuccess = function() { ... };
This can be translated as follows:
@JsType
public interface IDBRequest {
@JsProperty
public void onsuccess(Function fn);
}
@JsType
public interface IDBOpenDBRequest extends IDBRequest{}
@JsType
public interface IDBFactory {
public IDBOpenDBRequest open(String db, int version);
}
@JsType
public interface IDBEnvironment {
@JsProperty
IDBFactory indexedDB();
}
@JsType(prototype = window)
public interface Window extends IDBEnvironment{}
And use:
IDBOpenDBRequest req = Window.Static.get().indexedDB().open(db, 1);
req.onsuccess(Function.Static.newInstance(new FunctionObject, Void() {
@Override
public Void f(Object changed) {
console.log(changed);
return null;
}

when trying to execute the method with this snipped i get Exception
caught: (TypeError) : object is not a function
private native void test(Receiver receiver)/*-{
receiver.onReady();
}-*/;
to see whats the value of onReady i did console.log(receiver) and got
this: (where onReady is set the way above and onSenderConnected has been
set the JS way inside an JSNI method.
onReady: JsTest$1_1_g$
onSenderConnected: function (event_0_g$)
is there a way to achieve this yet or do i have to wait for 2.8/3.0?
i tried to dig into the gwt code to see if there is a way to add
something to support this but unfortunately the gwt code for js processing
is a bit out of my scope.
some possible solutions would be either
interface JsFunction {
T T call(Object... args);
}
or
interface MyOnReadyCallback {
@JsFunction
MyReturnType anyName(String arg1, boolean arg2, SomeOtherType arg3);
}
and let the Single Abstract Method Handling find the method and add it.
Thanks! :)

Re: [gwt-contrib] Deferred binding bug in 2.7
Without a repro case and debugging the best suggestion we have is to enable strict mode in your compilation. This might show some additional compilation errors but it's your best shot. When you are looking at the errors, you will probably see some errors in client.pages.AddParametersView.MyUiBinder or one of its references and that's probably the culprit.

I don't have a minimal repro case yet, and it might be tough to make one, but I do have a bit more information. The problem occurs when trying to compute the deferred binding result for some (not all) of the UiBinders in my application. When I run with loglevel=DEBUG, it's suggesting that there's a compilation failure when processing the one deferred binding rule I have in my top-level gwt.xml. That rule looks like this: replace-with class=client.environment.ProdEnvironment when-type-assignable class=client.environment.Environment/ /replace-with The log shows that everything works fine for most of the UiBinders - they skip over this rule (which is always the first one they check, probably because it's at the root of the inheritance chain) and eventually find the right one: Computing all possible rebind results for 'client.widget.band.BandView.MyUiBinder' Rebinding client.widget.band.BandView.MyUiBinder Checking rule replace-with class='client.environment.ProdEnvironment'/ Checking if all subconditions are true (all) when-assignable class='client.environment.Environment'/ No, the requested type was not assignable No: One or more subconditions was false Rule did not match Found better fallback match for replace-with class='client.environment.ProdEnvironment'/ Checking rule generate-with class='com.google.web.bindery.autobean.gwt.rebind.AutoBeanFactoryGenerator'/ Checking if all subconditions are true (all) when-assignable class='com.google.web.bindery.autobean.shared.AutoBeanFactory'/ No, the requested type was not assignable No: One or more subconditions was false Rule did not match Found better fallback match for generate-with class='com.google.web.bindery.autobean.gwt.rebind.AutoBeanFactoryGenerator'/ /* ... snip 100's of lines checking other rules */ Checking rule generate-with class='com.google.gwt.uibinder.rebind.UiBinderGenerator'/ Checking if all subconditions are true (all) when-assignable class='com.google.gwt.uibinder.client.UiBinder'/ Yes, the requested type was assignable Yes: All subconditions were true Rule was a match and will be used Invoking generator com.google.gwt.uibinder.rebind.UiBinderGenerator Parsing CSS stylesheet file:/var/folders/99/npwplk0x5s716r29tmllw_7hgn/T/uiBinder_client.widget.band_BandView_MyUiBinderImpl_GenCss_style1449650163126694696.css Generator returned type 'client.widget.band.BandView_MyUiBinderImpl; mode USE_ALL_NEW_WITH_NO_CACHING; in 15 ms Rebind result was client.widget.band.BandView_MyUiBinderImpl But for just a few UiBinders, it crashes when checking the deferred binding rule: Computing all possible rebind results for 'client.AddParametersView.MyUiBinder' Rebinding client.pages.AddParametersView.MyUiBinder Checking rule replace-with class='client.environment.ProdEnvironment'/ Checking if all subconditions are true (all) when-assignable class='client.environment.Environment'/ Tracing compile failure path for type 'client.pages.AddParametersView.MyUiBinder' Checked 0 dependencies for errors.

When I remove my deferred binding rule, the errors go away. There are no changes in my code other than switching the dependency from 2.6.1 to 2.7.0-rc1. Does this ring any bells around what the problem might be, or should I try digging deeper into figuring out what's different about the
