Re: why getPermutationStrongName is final and writeResponse is private?
How about writing a servlet filter instead, where you'd transform the permutation strong name from the query-string or payload (don't know how you send it) to a header before delegating down the chain to the servlet? ...or extending the servlet and doing similar things (transform the request and response, instead of changing how they're processed/generated) on the process() method. -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: Why does GWT's API differ so much from the Javascript one?
Which API do you find so much different from the native one? I don't think com.google.gwt.dom.client.* can be less different that the API it's making available to the GWT Java world. Same for com.google.gwt.canvas, com.google.gwt.geolocation, com.google.gwt.media, com.google.gwt.regexp, com.google.gwt.storage, and com.google.gwt.xhr.

Re: Does the GWT magic ever fail you?
Most of the time, you'll be debugging in DevMode, against your Java code, within your Java IDE, using any Java debugger. GWT 2.5 will generate SourceMaps so you can see your Java code in your browser's dev tools, set breakpoints in the Java code to pause the JS engine, etc. See https://plus.google.com/110412141990454266397/posts/iqXo5AyHkyd and http://www.2ality.com/2011/07/firefox-sourcemap.html In the mean time, or in browsers where SourceMaps aren't supported, GWT generates symbolMaps that allow you to find where an obfuscated function name comes from in your Java code. It can also be used to automatically deobfuscate stack traces (so you can, for instance, send a client-side exception to the server for logging –using java.util.logging and the SimpleRemoteLogHandler or RequestFactoryLogHandler–, and have the stacktrace automatically deobfuscated in your logs). You can also use the StackTraceDeobfuscator manually on the server-side; or look-up in the symbolMaps by yourself (I regularly do it when I can't reproduce a bug in DevMode). It's important to note that symbolMaps only map methods, whereas SourceMaps map down to the expression level. So no, it's not a problem. Also, if your application is big enough, even if you use plain JavaScript instead of GWT, you'll want to use a JS compiler (such as the Closure Compiler) or JS minifier; so you'll have the same issues. The Closure Compiler generates SourceMaps, but I don't think any compiler but GWT produces the equivalent of the symbolMaps and have the equivalent of the StackTraceDeobfuscator. -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

xtend thoughts
Hey, The xtend language [1] had a new release last week; they purport to be a better Java syntax but interestingly compile-down to Java source code, not Java byte code. Which means something like GWT can read the .java files and not care that the original language was not actually Java. As much as I like GWT, I will readily admit the aging Java syntax is not one of it's strengths, so have been actively looking for alternatives. Here are my thoughts on xtend/the syntax problem in general. * xtend itself seems kind of flaky--I could not get it to work by using their update site into my existing Eclipse installation. However, their update site has a long, complex list of features to choose, so I may have just choose the wrong one. * They also have a new distribution, which I did get to work, but only after deleting some code from their out-of-the-box sample project that for some reason wasn't compiling. It seems like I had to do a couple of clean builds before I finally saw things kick into gear and make some .java source files. These two points being said, it's a new project, so I have no problem with some rough edges. That being said, it also looks like: * If you run a junit test and it fails, and click on the failed method, Eclipse takes you to the generated .java file to show the failure. The generated .java files aren't necessarily ugly, but it seems like the point of a new syntax is to not have to look at the old one. * You cannot currently set debug points in .xtend files, you have to go to the generated .java files, set a debug point there. The Eclipse debugger will also step you through the generated Java code instead of the original .xtend code while you're debugging. So, this seems a little bit more odd to me. Perhaps it's something they can fix as the project matures, but I would really prefer the Eclipse tooling to use the original .xtend source files for debugging/etc. Applying xtend to GWT, it would probably result in the same issue--any errors/stack traces/debugging/etc. would be reported against the generated .java files, as GWT wouldn't know they should map back to whatever original .xtend source file. Which, I dunno, I guess might be fine to get a better syntax, but I don't think is ideal. So I'm still looking for more suitable Java.next contender that could integrate with GWT. In that regard, my current favorite is the scala-gwt project, which I've been helping out with a little bit.

Not at all. When you run in DevMode, you really run your Java code. The plugin you install in your browser calls your DevMode code server whenever it needs to reach your code; and when you use JSNI in your code, it's sent to the browser to be evaluated there. Debugging in Eclipse is then really just debugging Java code, connecting to the DevMode code server with no more than a basic Java debugger.

The answer to your question likely lies in the implementation of

indeed changed for the entity?

I hope my small note will help.
To increment the version I added method to entity class with two JPA

JPA EntityManager.merge() + Annotations are awesome.

Sessions and Activities and Places
What is a good way to have a GWT app redirect to a login screen when a
session expires? I've just hooked up a login page and a logout button
at an Activities and Places app. I basically handle this through the
event bus with login and logout events (haven't hooked up a session
time out yet).
The events work nicely. After logging in, the main place appears in
the app. When logging on, the login place appears. Very nice.
However, nothing prevents a user from accessing a place within the app
- either by bookmarking or using the back button after logging out.
I've experimented with a few things, but don't like any of them. For
example, in the AppActivityMapper if the user is not logged in, it
goes to the login place regardless of the requested place. I don't
like this because the URL still shows the requested place.
It looks like a central place to handle this is in
PlaceController.goTo(). While looking at the source, it appears that
changing places is handled via the event bus.
String warning = maybeGoTo(newPlace);

Has anyone tried overriding this to handle loggin/logout?

Re: GWT Developer Plugin for Firefox 8
Agreed. It would be nice to see this uploaded to SVN.

The latest and greatest is usually in SVN quickly if you are feeling adventurous. I am slightly hesitant to push it out to the official page because I don't want to break EVERY GWT user with a bad build. If you are downloading from the SVN, I assume you have no problem uninstalling a bad version if it didn't work for you. -Alan On Thu, Nov 10, 2011 at 11:52 AM, Thomas Broyer t.bro...@gmail.com wrote: It's been officially updated to FF7 yesterday (the XPI was downlodable for a long time already on the SVN): http://code.google.com/p/google-web-toolkit/source/detail?r=10735 -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Multiple Webapps - Can I Debug Only One?
Our website is Drupal driven and we drop in GWT scripts for some applications. In this particular page we have two applications on the same page. When I go to debug one it looks for the source of the other and fails. Doing both at the same time would be great but I only need one but I still want the other one to load as normal javascript should and not to try to attach to code in my debugger. Any tips on how to accomplish this? The html source (from a Drupal template). script type=text/javascript language=javascript src=/webapp- advancedtools/AdvancedTools/AdvancedTools.nocache.js/script script type=text/javascript language=javascript src=/webapp- activesearch/ActiveSearch/ActiveSearch.nocache.js/script I'm currently trying to attach to only my ActiveSearch application. And here is the error. 19:30:46.498 [ERROR] [AdvancedTools] Unable to find 'AdvancedTools.gwt.xml' on your classpath; could be a typo, or maybe you forgot to include a classpath entry for source? I added the AdvacedTools project to my run configuration for ActiveSearch but I haven't been able to get that to work either. Really that didn't feel like the right path anyways, I just want AdvancedTools to load like plain-old javascript. BTW, we're doing multiple applications because we need to maintain the ability to separately deploy one application without the other needing to be touched. I already realize the downfalls of the extra core css and javascript that is going to be doubled up on this page. I'd really appreciate any pointers here.
