Re: Compiling GWT Trunk w/ Tests : Can't get past 50K tests passed
On 16 March 2012 22:07, Joseph Lust lifeofl...@gmail.com wrote: For my personal edification I've setup TeamCity to build all new GWT updates from the Google SVN (yes, I checkout the tools folder too). Everything builds fine (7min), but when I enable the tests in Ant, per the official GWT build instructions, TC dies at 2h 15m to OutOfMemory errors. I've setup TC to run the JVM with 512MB PermGen and 4GB max heap, but it still only makes it to ~50,600 tests passed until it fails out. It dies around this point whether running 2GB, 3GB, or 4GB heap sizes (I had gotten PermGen errors earlier, but 512MB seems to have fixed that). So, my question is, does anyone else try building GWT with the tests? It seems like a rather obscene number of tests, but surely it works inside Google. And if you wonder why I am doing this, it is just to poke around and learn more about GWT, unit testings, and best dev practices in general. Build Machine Specs: Ubuntu 11.10, AMD FX8150 (unit tests utilize all cores), 16GB Ram, SSD. I tried the same thing (at least a year ago, though) and ran into the exact same problems. And also wondered whether anyone had ever run them all. :-) -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: GWT FileUpload - Servlet options and handling response
Check out the http://code.google.com/p/gwtupload/ project. Easy to use and extend. On Friday, March 16, 2012 10:27:39 PM UTC+1, Ashish wrote: I am new to GWT and am trying to implement a file upload functionality. Found some implementation help over the internet and used that as reference. But have some questions related to that: The actual upload or writing the contents of file on server(or disk) will be done by a servlet. Is it necessary that this servlet (say MyFileUploadServlet) extends HttpServlet? OR I can use RemoteServiceServlet or any other servlet or implement any other interface? If yes, which method do I need to implement/override? In my servlet, after everything is done, I need to return back the response back to the client. I think form.addSubmitCompleteHandler() can be used to achieve that. From servlet, I could return text/html (or String type object) and then use SubmitCompleteEvent.getResults() to get the result. Question is that can I use my custom object instead of String (lets say MyFileUploadResult), populate the results in it and then pass it back to client? or can I get back JSON object? Currently, after getting back the response and using SubmitCompleteEvent.getResults(), I am getting some HTML tags added to the actual response such as : pre Image upload successfully /pre . Is there a way to get rid of that? Thanks a lot in advance! Regards, Ashish -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: JBoss+WAR+RPC+GWT Concepts understanding
Anto, Honesty, you should download an existing, working sample project into Eclipse or your IDE of choice and run it. Then modify it as you snoop around and learn about it's inner workings. The best documentation of GWT and its workings is the Google documentationhttps://code.google.com/webtoolkit/overview.html. Read it all, and all of your above questions should be satiated. There are many existing projects available online, just Google for them and you'll find items like https://code.google.com/p/gwt-in-practice/ where you can get working examples of the war files, UI, RPC, etc. Sincerely, Joseph -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Node.js and other similar standalone JS runners (V8, SpiderMonkey, etc.), or things like http://code.google.com/p/google-js-test/ make it quite easy to write and run unit-tests too; and there are tools to run them in HtmlUnit or real browsers if you need (just like GWTTestCase).

Re: base64 to image in gwt client
I've used this Base64 class for both images and URL-safe encoding:

It is in the public domain.

Using @UiHandler for click event on custom widget
I have created a custom widget which is basically a HTMLPanel that extends
Composite and is styled as a button.
I'm using the widget with UiBinder, but I want to use the @UiHandler
annotation inside the view where the button
is located and catch its click event.
How can I do this? I have tried doing something like this but it doesn't
work:
@UiField
HTMLPanel mainContainer;
@UiConstructor
public CustomButton(String text)
{
initWidget(binder.createAndBindUi(this));
setText(text);
mainContainer.addDomHandler(new ClickHandler()
{
@Override
public void onClick(ClickEvent event)
{
Window.alert(Clicky);
fireEvent(event);
}
}, ClickEvent.getType());
}
In my view:
@UiHandler(customButton)
public void customButton(ClickEvent event)
{
Window.alert(Clicky!);
}
I get error:
[ERROR] Field 'customButton' does not have an 'addClickHandler' method
associated.

Re: Using @UiHandler for click event on custom widget
Just implement the interface HasClickHandlers in your custom button so you
have an addClickHandler() method.
public CustomButton extends Composite implements HasClickHandlers {
public HandlerRegistration addClickHandler(ClickHandler handler) {
return addDomHandler(handler, ClickEvent.getType());
}
}

Re: The import com.google.gwt.user cannot be resolved
Please be sure that you import gwt-user.jar to your buildpath.Good luck to
you.

There's nothing to fix in that code. You're probably missing something in
your setup (classpath, *.gwt.xml, I don't know)

Re: [gwt-contrib] Mavenizing GWT
On 16 March 2012 20:26, Ray Cromwell cromwell...@google.com wrote: I agree with most of this, but I just wanted to mention that I think breaking up the dependency chain will be a little tricky for maven when it comes to tests. Maven general practice is that a given module contains its tests and runs them. The problem with gwt-dev and gwt-user is that many of the gwt-user tests can't run unless gwt-dev has been built, but gwt-dev IIRC has some tests that depend on gwt-user. So it may be that you need to make separate gwt-dev-tests/gwt-user-tests subprojects. Personally, I'd like to break up GWT-user further into lots tiny pieces, like Core, I/O, Emulation, RPC, Widgets, DOM/Media/HTML, etc We can still build an uber gwt-user.jar, but there are lots of projects that don't use everything, and being able to move stuff off of the classpath speeds up the compiler and dev-mode. There are some projects like PlayN for example, that pretty much only use Core. Yes, that would be wonderful! -- http://groups.google.com/group/Google-Web-Toolkit-Contributors
[gwt-contrib] Issue 7038: CompositeEditor and ListEditor optimizations (issue1664803)
Reviewers: rdayal,
Description:
Issue 7038: CompositeEditor and ListEditor optimizations
Initializer and Refresher visitors cause CompositeEditors' sub-editors
to be visited twice: once by the EditorChain#attach() they should be
calling in their setValue, and then once again by the visitor stepping
into sub-editors.
When a CompositeEditor has a ListEditor as a sub-editor, that ListEditor
then would create a ListEditorWrapper twice in a row, leading in
creating
sub-editors to dispose them right away, which is obviously bad for
performance.
Having the Initializer and Refresher avoid visiting CompositeEditors'
sub-editors (because setValue would have already done so) fixes the
issue.
Additionally, ListEditor unconditionally recreate its ListEditorWrapper
in setValue even when setting the same value as the one being edited.
This
leads to recreating all sub-editors instead of reusing them (even though
the EditorSource should take care of this already for best performance
in
all cases).
