Are GWT widgets leak memory ?
It seems that GWT widgets are leaking memory. For testing i have
created a sample application which create a series of panels
containing Labels. If i allocate 1000 panels and clear() all of them
there are still around 1K memory remain to get free. Here is the
code i have written
/**

public class Test implements EntryPoint {
VerticalPanel tableRowContainer;
VerticalPanel mainVerticalPanel;

Button addButton = new Button(Add);
Button removeButton = new Button(Remove);
Button clearButton = new Button(Clear);
Button exitButton = new Button(Exit);
tableRowContainer = new VerticalPanel();
mainVerticalPanel = new VerticalPanel();
textbox = new TextBox();
addButton.addClickHandler(new ClickHandler(){
@Override
public void onClick(ClickEvent event) {
String tbText = textbox.getText();
int num = Integer.parseInt(tbText);
for (int i = 0; i num ; i++) {

FlexTable and UiBinder
I'm currently working on an UiBinder based application, where I'd like to use a FlexTable to hold data for a form (the labels plus the text boxes). Unfortunately, it seems that UiBinder does only allow to declare the FlexTable, but not the elements of the FlexTable. As there are quite a lot of elements, I'd like to decleare them in UiBinder too (otherwise it would not make sense to use UiBinder in my application). What's the suggested way to do this? In an older post I read the suggestion to add the widgets at some other place in the UiBinder XML file and then to programmatically move them to the right place in FlexTable. That's what I currently do: I add the widgets to a HorizontalPanel in UiBinder, then in onModuleLoad() I manually use FlexTable.setWidget() to move them to the FlexTable. Afterwards, I delete the HorizontalPanel as it's not required anymore. Is there currently a better or a cleaner way to do this? Or is this type of solution currently the best option? Are there any other tables that offer functionality similar to FlexTable and that I can declare in UiBinder (I need labels and text boxes vertically aligned, each in multiple columns. Additionally, some of the rows have colspan larger than one.)? - Guenther -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: Google Plugin for Eclipse 1.3 Preview is now available
Hey Keith, thank you very much for all the details. For now we actually decided to stick with the goals provided by gwt-maven, so I'm sorry I did not check your points by now. I'll create a new project and check your advices, especially the correct source folders in the GEP launch config, which actually was the only thing I did not look after. I'll drop in a message soon. Andreas On 15 Mrz., 21:05, Keith Platfoot kplatf...@google.com wrote: @Andreas: Forgot to mention that if you're *not* using Eclipse for Java EE, when you make changes to server-side code, you will also need to restart GWT embedded Jetty instance.

Keith On Mon, Mar 15, 2010 at 2:27 PM, Keith Platfoot kplatf...@google.comwrote: Hi Andreas, It looks like you're following the correct procedure, and you indicated that you were able to load the application in devmode, but you're not seeing code changes reflected when you Refresh the browser. It might help if I explain briefly how changes are *supposed* to be reflected, and suggest a few ideas for things to check if refresh is not working: - Client-side code changes should *always* be reflected when you click Refresh in your browser during a devmode session, regardless of your source folders' build output paths. This is because GWT devmode is actually using your .java source files, not the compiled .class files. Double-check in your launch configuration's Classpath tab that your source folders appear at the top of the User Entries section. If your gwt:run goal *does*correctly reflect code changes in devmode when you Refresh, it would be useful to compare the devmode process arguments in that case to the devmode process created by the Eclipse launch configuration (you can find the arguments in Eclipse by right-click Properties the java process in the stacktrace view in the Debug perspective). Let me know if there are differences between the two sets of arguments. - Server-side code changes will only be reflected if the compiled .class files are propagated to your runtime WAR directory's WEB-INF/classes directory. As you mentioned, one way to do this is to set your source folders' build output paths to your runtime WAR directory's WEB-INF/classes directory. Of course, Eclipse must also be configured to build automatically (Project Build Automatically). If server-side code refresh is still not working, you might try making a change, and then manually verifying that the runtime WAR directory is getting the new .class file in WEB-INF/classes. - Changes to your HTML/CSS/other static resources will need to be mirrored in your runtime WAR directory (similar to server-side code changes). I'm not aware of any out-of-the-box solution for this if you're using a standard Eclipse distribution (Eclipse Classic or Eclipse for Java developers). You'll need to stop devmode, do another 'mvn clean package', and then launch devmode again. However, if you're using Eclipse for Java EE, there is a way to configure it to automatically push WAR resource changes while devmode is running (this should answer your question in your #3 step). Basically, you start by converting your project into a Dynamic Web Project. I don't know if you can automatically migrate an existing project, but it should be possible to create a new Dynamic Web Project and then simply import your original project's source folders and build path entries. Next, you'll need to configure the Eclipse project to use 'src/main/webapp' as your WAR directory instead of 'WebContent' (Eclipse default). Close Eclipse and edit the file at: project root/.settings/org.eclipse.wst.common.component. Find the wb-resource element with a 'source-path' attribute of '/WebContent'. Change the attribute value to '/src/main/webapp', save the file, and re-open Eclipse. Now, when you start the project's configured server (Tomcat, Jetty, etc... define a server in the Servers view), Eclipse will automatically propagate changes in your source code and static resource files to your runtime WAR directory. However, in Eclipse for Java EE, this runtime WAR directory will *not* be 'target/exploded WAR'. Eclipse will instead create a staging directory in a temporary location (by default, workspace/.metadata/.plugins/org.eclipse.wst.server.core/tmp0/wtpwebapps/project) and *this* is the WAR directory you'll need to select when launching the Web Application launch configuration. One more note: Eclipse for Java EE will also automatically push your updated .class files into WAR/WEB-INF/classes, so no need to manually change your source folders' build output paths. Does that all make sense? At launch, we'll be adding a couple new FAQ entries to our documentation to

gwt-maven runTarget configuration breaks resource paths
Hey everyone, we are developing GWT applications using maven, gwt-maven-plugin, Eclipse 3.5 EE and m2eclipse. We are currently having some problems setting up a proper run configuration (based on mvn gwt:run goal) that seem to come from wrong paths to resources. Apparently the runTarget tag is used to specify the resource to launch in DevMode. As the documentation says, one can insert the full module path there appended by the resource (/Application.html) IF that resource is located in the modules public folder. The plugin then replaces the module path by the value of the rename-to directive. Now GWT compiler creates a folder named like the rename-to directve value and puts all generated resources in there, namely the generated js-files and the gwt stuff. BUT gwt-maven also puts all other resources in there that is your Application.html which includes the script tag and other files like Application.css for example. Now in order to make the application work in Tomcat (our deployment target) one needs to adjust all resource references starting from the welcome-file in web.xml to all other includes in the Application.html as ther are the script tag and css-includes to match the location inside the folder named after the rename-to directive. But with this configuration the application can not be run in DevMode since DevMode prepends the rename-to directive to all GET request which leads to 404 when requesting the nocache.js (and css and so on, but missing nocache prevents everything else from happening; only white empty html). It requests them from rename-to/rename-to/rename- to.nocache.js, where rename-to is what you entered in your modules rename-to directive. The correct path would be rename-to/rename- to.nocache.js Now where is the problem? How can I configure the runTarget or the paths GWT creates to be the same in DevMode as deployed on Tomcat? Thanks in advance. Andreas P.S.: I remember pure GEP-Projects placing the application html in the root directory of the web application, but gwt-maven does not, maybe that is one reason it conflicts. In our case it even is a pure GEP project we converted to a gwt-maven one. gwt-maven also uses index.html and simply redirects to the application html. -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: iFrame in TabPanel Reload Problem
Still haven't found a solution. Anyone out there have a clue what to do? On Mar 4, 3:49 pm, John john.m.daugh...@gmail.com wrote: Any help would be appreciated! Firefox reloads the contents of iframes when they are unhidden. So, if you have a TabPanel, where each tab holds an iframe, moving between tabs reloads the frame. Chrome and IE leave the frame alone, but Firefox closes it when you hide it. For example, if you have a youtube movie up in a frame on one tab, and move to another, the movie keeps playing in the background in Chrome and IE (as it should). In Firefox, the movie stops. And, when you return to the tab, Firefox reloads the page, causing the movie to start over. The fix for this in Firefox is to not hide the frame, but to make it invisible by reducing its size to 0 when you click on another tab. This seems like the type of legitimate JS browser-specific hack that GWT's compiler is good for. Has anyone implemented this fix? How do you even go about making this fix?

Re: FlexTable and UiBinder
Why not use a HTML panel and inside define a HTML table with the widgets in the cells? I rarely use things like FlexTable, HorizontalPanel or VerticalPanel. Usually all my forms are a combination of pure HTML and widgets.

Re: RPC and MapString, Object serialization problem

I was thinking what Paul's solution to take and I like 1st one with:

However, I don't see what way GWT serializer may know in this service
method:
HashMapString, Property? getFoo();
what type of Property can be received - is it not the same problem as
in HashMapString, Object getFooWithObject();

GWT does a great job of putting as little into the javascript as
possible. In the above case, there's nothing to tell it that you're
going to send a Long, so it doesn't generate theRPCcode into the
javascript that knows how to deserialize a Long. Add another method that
references Long, and then your first method might work because the Long
code is now going to be included.
On a related note, using Map in the API is not a good idea because it
means GWT must look through all your code for every implementation of
Map to see whether it's used. At the very least, it will make compiles
take longer. At worst, it will generate longer code. It goes against the
grain for java programming, but you need to make GWTRPCAPIs as
specific as possible. That means declaring that you're returning a
HashMap, not a Map, in the interface.
This also means you can't declare Object as a type in anRPCinterface.

Re: RPC and MapString, Object serialization problem
It's not the same problem.
With an RPC method of HashMapString, Property? getFoo(), where
Property is abstract, GWT will look for all subclasses of Property on
the classpath and build the RPC code for them. If you have one Property
subclass per data type, then since the Property subclasses explicitly
reference the underlying data type (like Long), the RPC code for those
data types will be included as well.
You might also like to check out this issue related to RPC of cyclic
object graphs when using HashMap/HashSet if you use this technique:

It consists of two panes, content and navigation/search; implemented as a HorizonatalSplitPanel containing a ScrollPanel for the content and a DecoratedTabPanel which contains a Tree for the navigation. So far, so good. For mouse-wielding sighted users, it all works as expected. Clicking TreeItems in the navigation causes the content ScrollPanel to get new content. For keyboard-wielding screen-reader users, however, it's not so good. One can tab around to get focus to the navigation. One can arrow-key around the navigation tree to update the content pane (sighted users can see the content pane updating). But the updates to the content pane are inaudible in the screen-reader JAWS. After reading the documentation at http://code.google.com/webtoolkit/doc/latest/DevGuideA11y.html , I added the following lines to the constructor for our content ScrollPanel: com.google.gwt.user.client.Element e = this.getElement(); Accessibility.setRole(e, document); Accessibility.setState(e,aria-live, rude); Accessibility.setState(e,aria-atomic, true); Accessibility.setState(e,relevant, additions); I've also tried with role=region, with other rudeness levels, and without the aria-atomic and relevant attributes. I've verified that the html delivered to the browser does contain the correct attributes on the div (div class=contentBrowserPanel relevant=additions aria- atomic=true aria-live=rude role=document style=overflow: auto; position: relative;). According to http://wiki.codetalks.org/wiki/index.php/How_to_use_ARIA_Live_Regions_for_dynamic_content , this should do exactly what I want. But still no love from the JAWS. We are using Windows XP, Firefox 3, IE 7, and JAWS 11. I thought the problem might be that JAWS is confused with the iframes GWT used to implement the HorizontalSplitPanel. But my visual-impaired user who originally reported the problem reports that none of JAWS iframe-reading commands caused it to properly read the content pane. Has anyone run into similar issues? I saw one post where the author just decided to make a non-AJAX version available from a hidden link. We may have to go that route eventually, but I was hoping there is a simple solution. -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: GWTCanvas - Is this a Bug?
Hate to break it to you but your code is broken on Chrome as well... I mean it appears to redraw some shape on the second row of content and then many more times off horizontally.

Obfuscate java source
Hi. I'm developing a GWT library. And I would like to be able to obfuscate the java source code in the .jar file to be able to give the library to others without them reading the code. I know that the way most of us write code it's obfuscated by default, but .. :) Could anyone recomend a tool to do this? //Rasmus Gxt-Schdeuler Team -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: Eclipse JavaEE tools + GWT Development mode
Hi Keith, can you tell how to configure Eclipse + Google Plugin for Eclipse (the newest version), so I can debug my GWT project with DB connections? Your previous solution doesn't work anymore (I can't find anythig about WAR in Web Application property). Thanks in advance, Neciu. On 18 Lut, 17:40, Keith Platfoot kplatf...@google.com wrote: Hi Chris, Thanks for posting this. It's a good explanation of how to get WTP and GPE 1.2 working together, which is not a trivial task. However, in the next release of the plugin we're planning on making this integration a whole lot easierhttp://groups.google.com/group/google-web-toolkit/msg/8ff67143cce64e1... . With GPE 1.3, you'll be able to adapt an existing Dynamic Web Project as a GWT project and debug using hosted/dev mode quite easily. Here's a sneak preview of how this will work in GPE 1.3: 1. In your project's Properties dialog, select Google Web Toolkit and check the box: *Use Google Web Toolkit*. 2. Switch to the Web Application property page and change *WAR source directory* to WebContent and uncheck the box: *Also use this directory as the output WAR directory.* * * 3. Start your project's server (be it GlassFish, Tomcat, etc.) using your configured WTP server adapter. 4. Create a new Web Application launch configuration. On the Server tab, uncheck: *Run built-in server* (since we want to use WTP's server adapter) and on the GWT tab, change the -startupUrl argument to point to your server (e.g.http://localhost:8080/WebApp) 5. Run/Debug your new launch configuration. The first time you do this, you'll have to select the location of the WAR directory WTP is publishing to (this is configurable, but I think by default it is workspace/.metadata/.plugins/org.eclipse.wst.server.core/tmp0/wtpwebapps/project). 6. Presto! GWT hosted/dev mode is now running in your own server, and you can debug either server-side or client-side code, and get automatic redeploy of modified class files or static resources thanks to WTP's auto-publish mechanism. We're going to be uploading a preview built of GPE 1.3 later this month so you can try it out for yourself and let us know what you think, ahead of the official release. Stay tuned!

Sending HTTP GET request not working!
Hi,
I'm trying to send a HTTP GET request to a server on localhost (http://
localhost:8080/wps/WebProcessingService?
Request=GetCapabilitiesService=WPS) and for some reason it won't
work. I've inherited the GWT HTTP module as shown here:
http://code.google.com/webtoolkit/doc/latest/DevGuideServerCommunication.html#DevGuideHttpRequests
My code is based on the code in the above link:
final String capabilitiesUrl = wpsInput.getText();
RequestBuilder builder = new RequestBuilder(RequestBuilder.GET,
URL.encode(capabilitiesUrl));
try {
Request request = builder.sendRequest(null, new RequestCallback() {
@Override
public void onResponseReceived(Request request, Response
response) {
Window.alert(URL.encode( + response.getStatusCode()));
}
@Override
public void onError(Request request, Throwable exception) {
Window.alert(ERROR);
}
});
} catch (RequestException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
However, the response keep coming up as status code 0 and seems to be
empty. I don't get an errors. The URL is fine - if I copy it into my
browser it shows the XML response.
Anyway have any idea what I'm doing wrong?
Cheers!
Jon

Re: Google Plugin for Eclipse 1.3 Preview is now available
Hi Keith, Thanks for the improvements !! I've got a clean Maven Web project like I used to work with before trying GWT ! :) However, Eclipse seems to keep the folder /war and /war/WEB-INF in my project. Even if I delete it, it keeps appearing. Any clue on this behaviour ? Cheers, Simon On 4 mar, 01:25, Keith Platfoot kplatf...@google.com wrote: Hi everyone, Last month, I announced some of the changes we had planned for the 1.3 version of the Google Plugin for Eclipse. To recap, this release is focused on making life easier for developers using GWT/App Engine alongside third-party tools, including Maven and Eclipse for Java EE. In my post, I promised we'd let you download a preview of 1.3 to get some hands-on testing of the new features and provide us with your feedback before the official release. I'm happy to announce that the time has come. An early preview of 1.3 is now available for download at the following URLs: http://dl.google.com/eclipse/plugin/3.5/zips/com.google.gdt.eclipse.s... http://dl.google.com/eclipse/plugin/3.4/zips/com.google.gdt.eclipse.s... http://dl.google.com/eclipse/plugin/3.3/zips/com.google.gdt.eclipse.s... Note: Ensure that your version of Eclipse has Eclipse's Web Standard Tools (WST) installed before installing the plugin. WST can be installed by navigating to the Software Installation section, and selecting the the appropriate WST feature from the update site for your version of Eclipse. The update sites and feature names are provided below: - 3.5 (Galileo): Galileo Web, XML, and Java EE Development Eclipse Web Developer Tools - 3.4 (Ganymede): Ganymede Update Site Web and Java EE Development Web Developer Tools - 3.3 (Europa): Europa Discovery Site Web and JEE Development Web Standard Tools Project This is a preview build, so the usual caveats and warnings apply: it is not officially supported, and we recommend using a clean installation of Eclipse and a new workspace. Also, we're distributing this preview as a zip file so be sure to follow the instructions on our Installing the Google Plugin for Eclipse from zip files page (http://code.google.com/eclipse/docs/install-from-zip.html). *Known Issues* - If you change launch configuration settings in the Server or GWT tab, you'll need to switch to the Arguments tab before clicking Apply or Run/Debug. This will be fixed in the final release. That being said, we are very interested in your experience with this new release, which we hope will allow the Google plugin to interoperate much better with alternative project structures and third-party tools. The tentative 1.3 release notes are as follows: Enhancements - Configurable WAR directory to allow better integration with Eclipse for Java EE http://www.eclipse.org/downloads/moreinfo/jee.php and projects built with Maven http://maven.apache.org/ - Web Application launch configurations now display and allow editing of generated Program and VM arguments - Errors/Warnings preference page for customizing the severity of any generated problem marker - Projects can reference GWT/App Engine SDKs directly via JARs instead of through SDK library - GWT+App Engine projects automatically configured for optimal caching Fixes - GWT Issue 3583http://code.google.com/p/google-web-toolkit/issues/detail?id=3583: Google Eclipse Plugin configuration is too strict - GWT Issue 3592http://code.google.com/p/google-web-toolkit/issues/detail?id=3592: Eclipse plugin to add 'cache forever' configuration for new 'GWT + App Engine' projects - GWT Issue 3902http://code.google.com/p/google-web-toolkit/issues/detail?id=3902: Allow users to configure the severity of problems reported by the eclipse plugin - App Engine Issue 1515http://code.google.com/p/googleappengine/issues/detail?id=1515: Eclipse plugin requires fixed location for war directory - App Engine Issue 2115http://code.google.com/p/googleappengine/issues/detail?id=2115: Using the @PersistenceAware annotation puts the Eclipse Enhancer in an Infinite Loop - App Engine Issue 1941http://code.google.com/p/googleappengine/issues/detail?id=1941: Plugin fails to enhance dependent classes on source level changes For a complete list of fixed issues, see the GWT issue trackerhttp://code.google.com/p/google-web-toolkit/issues/list?can=1q=label... and App Engine issue trackerhttp://code.google.com/p/googleappengine/issues/list?can=1q=label:GP... . We encourage all interested developers to take the preview build for a spin, and let us know what you think.

Do you always have an enormous front-prensenter?
Hi, I am new to gwt as well as mvp. We are building a site with gwt- front talking with a legacy server via simple json. I looked through the gwt-mvp sample with gwt-presenter. It seems its mainPresenter acts like a front-controller (dispatch-servlet in Spring mvc)? We are trying to layout the page with a header (menu), a footer (staus bar) and center. The center changes and we have about 15-25 different types for center content (may growing into ~100 later). My understanding is that each of these corresponds to a presenter, which might be called by MainPresenter. Then do you need to inject all of them into the MainPresenter? That seems a really large MainPresenter to build, with a huge constructor to inject. Am I thinking in the right line? Is there any other way to break it down?

Multiple entrypoints? Or something else?

Re: Multiple entrypoints? Or something else?
Hello, if you mean each * is a totally different webpage, that you cannot navigate between them with a Hyperlink (History state application), yes, you need more Entrypoints... Each entrypoint is like a new webpage inside your project. With their own MyApp1.gwt.xml and their own /myapp1/ directory at /war/ Your .html page can be any name you want... you just need to redirect the myapp1.nocache.js inside the .html page. -- Francisco Bischoff http://www.cirurgiaplastica.pro.br O mate está para o gaúcho como o chá para os ingleses, a coca para os bolivianos, o uísque para os escoceses e o café... para os brasileiros -- Eduardo Bueno On Tue, Mar 16, 2010 at 1:03 PM, jbdhl jbirksd...@gmail.com wrote: I would like to build a website, using GWT together with Google App Engine.There are three parts, but how should I organize them? * Users can login and customize a service to be included in a DIV on their own homepages (just like e.g. google maps can be included in a homepage).

Re: Sending HTTP GET request not working!
Ignore the URL.encode(...) part of the alert box, that was there
because of a dodgy copy and paste! I've removed it now.
Also, I've looked at my Tomcat log and my requests are being received
fine... but I still can't access the response from GWT.

GWT + Visualization API : Remove handler from a chart
Hi, Is there any way to remove the registered handler from the chart? My idea is to add a new handler on some user action. When I register a new select handler for this chart, it adds up this new event in a list of select events for the same chart hence causing the select event to get triggered first for the earlier registered event and then the new select event.

Cheers, Simon On 4 mar, 01:25, Keith Platfoot kplatf...@google.com wrote: Hi everyone, Last month, I announced some of the changes we had planned for the 1.3 version of the Google Plugin for Eclipse. To recap, this release is focused on making life easier for developers using GWT/App Engine alongside third-party tools, including Maven and Eclipse for Java EE. In my post, I promised we'd let you download a preview of 1.3 to get some hands-on testing of the new features and provide us with your feedback before the official release. I'm happy to announce that the time has come. An early preview of 1.3 is now available for download at the following URLs: http://dl.google.com/eclipse/plugin/3.5/zips/com.google.gdt.eclipse.s... http://dl.google.com/eclipse/plugin/3.4/zips/com.google.gdt.eclipse.s... http://dl.google.com/eclipse/plugin/3.3/zips/com.google.gdt.eclipse.s... Note: Ensure that your version of Eclipse has Eclipse's Web Standard Tools (WST) installed before installing the plugin. WST can be installed by navigating to the Software Installation section, and selecting the the appropriate WST feature from the update site for your version of Eclipse. The update sites and feature names are provided below: - 3.5 (Galileo): Galileo Web, XML, and Java EE Development Eclipse Web Developer Tools - 3.4 (Ganymede): Ganymede Update Site Web and Java EE Development Web Developer Tools - 3.3 (Europa): Europa Discovery Site Web and JEE Development Web Standard Tools Project This is a preview build, so the usual caveats and warnings apply: it is not officially supported, and we recommend using a clean installation of Eclipse and a new workspace. Also, we're distributing this preview as a zip file so be sure to follow the instructions on our Installing the Google Plugin for Eclipse from zip files page (http://code.google.com/eclipse/docs/install-from-zip.html). *Known Issues* - If you change launch configuration settings in the Server or GWT tab, you'll need to switch to the Arguments tab before clicking Apply or Run/Debug. This will be fixed in the final release. That being said, we are very interested in your experience with this new release, which we hope will allow the Google plugin to interoperate much better with alternative project structures and third-party tools. The tentative 1.3 release notes are as follows: Enhancements - Configurable WAR directory to allow better integration with Eclipse for Java EE http://www.eclipse.org/downloads/moreinfo/jee.php and projects built with Maven http://maven.apache.org/ - Web Application launch configurations now display and allow editing of generated Program and VM arguments - Errors/Warnings preference page for customizing the severity of any generated problem marker - Projects can reference GWT/App Engine SDKs directly via JARs instead of through SDK library - GWT+App Engine projects automatically configured for optimal caching Fixes - GWT Issue 3583http://code.google.com/p/google-web-toolkit/issues/detail?id=3583: Google Eclipse Plugin configuration is too strict - GWT Issue 3592http://code.google.com/p/google-web-toolkit/issues/detail?id=3592: Eclipse plugin to add 'cache forever' configuration for new 'GWT + App Engine' projects - GWT Issue 3902http://code.google.com/p/google-web-toolkit/issues/detail?id=3902: Allow users to configure the severity of problems reported by the eclipse plugin - App Engine Issue 1515http://code.google.com/p/googleappengine/issues/detail?id=1515: Eclipse plugin requires fixed location for war directory - App Engine Issue 2115http://code.google.com/p/googleappengine/issues/detail?id=2115: Using the @PersistenceAware annotation puts the Eclipse Enhancer in an Infinite Loop - App Engine Issue 1941http://code.google.com/p/googleappengine/issues/detail?id=1941: Plugin fails to enhance dependent classes on source level changes For a complete list of fixed issues, see the GWT issue trackerhttp://code.google.com/p/google-web-toolkit/issues/list?can=1q=label... and App Engine issue trackerhttp://code.google.com/p/googleappengine/issues/list?can=1q=label:GP... .

Class in jar file used in another GWT application gives *Source not available* error when compiling
Hi, I am trying ot use the DatePicker that the user created here: http://advanced-gwt.sourceforge.net/demo/index.html = *Text and Button Widgets* tab = Select a date. In the *Source Code* section it imports this: import org.gwt.advanced.client.ui.widget.DatePicker; I downloaded the relative jar and imported it in my EntryPoint class. In Eclipse i F3 on it to see the source code, and it opens DatePicker in package org.gwt.advanced.client.ui.widget, which is the one that I want. And it means that the source is there. Try to compile it and I get the error copied below. I believe i need to inherit it, or need to specify the source path in Monkee.gwt.xml, but don't know how to do it. And the source code of the whole project I downloaded is a bit too complicated for me to understand, as I am still a beginner. Does anyone have an idea? Also, not being a GWT standard widget, can it still be declared in a UIBinder xml? Thanks a lot in advance!

Re: Google Plugin for Eclipse 1.3 Preview is now available
I resolved this issue. It turns out that WTP included Tomcat 5.5 as a runtime dependency (default in the project). When I removed this dependency, everything started working (i.e. UIBinder stuff).

Keith On Mon, Mar 15, 2010 at 2:27 PM, Keith Platfoot kplatf...@google.comwrote: Hi Andreas, It looks like you're following the correct procedure, and you indicated that you were able to load the application in devmode, but you're not seeing code changes reflected when you Refresh the browser. It might help if I explain briefly how changes are *supposed* to be reflected, and suggest a few ideas for things to check if refresh is not working: - Client-side code changes should *always* be reflected when you click Refresh in your browser during a devmode session, regardless of your source folders' build output paths. This is because GWT devmode is actually using your .java source files, not the compiled .class files. Double-check in your launch configuration's Classpath tab that your source folders appear at the top of the User Entries section. If your gwt:run goal *does*correctly reflect code changes in devmode when you Refresh, it would be useful to compare the devmode process arguments in that case to the devmode process created by the Eclipse launch configuration (you can find the arguments in Eclipse by right-click Properties the java process in the stacktrace view in the Debug perspective). Let me know if there are differences between the two sets of arguments. - Server-side code changes will only be reflected if the compiled .class files are propagated to your runtime WAR directory's WEB-INF/classes directory. As you mentioned, one way to do this is to set your source folders' build output paths to your runtime WAR directory's WEB-INF/classes directory. Of course, Eclipse must also be configured to build automatically (Project Build Automatically). If server-side code refresh is still not working, you might try making a change, and then manually verifying that the runtime WAR directory is getting the new .class file in WEB-INF/classes. - Changes to your HTML/CSS/other static resources will need to be mirrored in your runtime WAR directory (similar to server-side code changes). I'm not aware of any out-of-the-box solution for this if you're using a standard Eclipse distribution (Eclipse Classic or Eclipse for Java developers). You'll need to stop devmode, do another 'mvn clean package', and then launch devmode again. However, if you're using Eclipse for Java EE, there is a way to configure it to automatically push WAR resource changes while devmode is running (this should answer your question in your #3 step). Basically, you start by converting your project into a Dynamic Web Project. I don't know if you can automatically migrate an existing project, but it should be possible to create a new Dynamic Web Project and then simply import your original project's source folders and build path entries. Next, you'll need to configure the Eclipse project to use 'src/main/webapp' as your WAR directory instead of 'WebContent' (Eclipse default). Close Eclipse and edit the file at: project root/.settings/org.eclipse.wst.common.component. Find the wb-resource element with a 'source-path' attribute of '/WebContent'. Change the attribute value to '/src/main/webapp', save the file, and re-open Eclipse. Now, when you start the project's configured server (Tomcat, Jetty, etc... define a server in the Servers view), Eclipse will automatically propagate changes in your source code and static resource files to your runtime WAR directory. However, in Eclipse for Java EE, this runtime WAR directory will *not* be 'target/exploded WAR'. Eclipse will instead create a staging directory in a temporary location (by default,

Re: GWT Grid vs. SmartGWT grid
The Grid class from GWT is a layout handler and not a GUI widget at all. I suspect that you are looking for some kind of data table GUI widget control. The ListGrid control from the SmartGWT project has all the nice bells and whistles but the download can be less than snappy. I don't think that it is too bad though. Check out http://myjsp.dynamicalsoftware.com/kato/ which is a demo containing many SmartGWT widgets including the ListGrid. I wouldn't say that the download was too terrible. SmartGWT works fine on many popular browser/OS combinations. The only place I found of relevance where SmartGWT doesn't work and GWT does is the iPhone. The Grid control from the GXT project might be a nice compromise between eye candy and download time but do check out their license first. @Mariyan has already recommended the PagingScrollTable from the incubator project. Also, you might be interested in this presentation ( see http://www.dynamicalsoftware.com/gwt ) on GWT and some popular yet mature 3rd party libraries. The slide deck covers the very topic that you are asking about. I hope this helps. On Mar 11, 9:12 pm, Ken evotur...@gmail.com wrote: I'm exploring using GWT for future work and for a project I'm looking at now I'm particularly interested in the Grid widget. The GWT Grid just doesn't compare to that provided by SmartGWT, but I'm concerned about using the SmartGWT libraries for several reasons: 1) It requires taking the whole library whole and it doesn't do things in really the same way that GWT does in many cases. 2) I'm concerned about browser compatibility since it relies on JSNI calls to the Smart Client library and not the Java-JavaScript transformation provided by GWT. 3) I'm concerned that by using the SmartGWT library I will be increasing the load time of the application since it will require downloading the entire library again. So what I would really like is a grid control that has a similar feature set as that provided by SmartGWT, but doesn't come with all the extra baggage. Does such a widget exist? Is there at least a JavaScript grid that can be used with GWT that doesn't come with all the baggage of SmartGWT? Am I wrong about the disadvantages to using SmartGWT? Is it a better choice than I have been led to believe by my research? Thank you. -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: JAXB compatibility with GWT 2.0, any news?
I haven't tried it recently, but JAXB generated classes should work. Earlier, the GWT compiler choked on annotations. It now ignores these annotations when it compiles java into js. You would need to keep the jaxb jars in your compile classpath, but that should be all that you need to do. Could you try compiling jaxb classes and let us know?

Re: Google plugin 1.3 preview and jar SDK
Hi Mickaël, Thanks for your feedback about the 1.3 preview of the Google Plugin for Eclipse. The 1.3 version does allow you to use the GWT jars from your Maven repo, but as you discovered, it will not recognize the filenames if you try to add it to the set of registered SDKs via the Google GWT preference page. Instead, just add the jars directly to your project's build path and then enable GWT for the project (project properties Google GWT). As of version 1.3, the plugin will recognize the jars on your classpath as a valid GWT SDK, even though they have been renamed. In versions of the plugin prior to 1.3, you would have seen an error that your project did not contain any GWT SDK. You may file a bug in the issue tracker if you feel that this behavior is incorrect, since the official 1.3 release will work the same way regarding that feature. Keith 2010/3/15 LEDUQUE Mickaël mledu...@gmail.com Hello, I tested the 1.3 preview for the plugin, and one of the nice new feature is the ability to use a gwt-user JAR instead. So I tried to use the gwt-user-2.0.3.jar file that is in my maven2 local repository. But when I set Installation drectory to the good path in the Add Google Web Toolkit SDK dialog, all I get is my repo path/com/google/gwt/gwt-user/2.0.3/gwt-user.jar is missing. That's right because the name is gwt-user-2.0.3.jar, not gwt-user.jar. I think it'd be better to let the user configure jar name as well as path.

Anyway have any idea what I'm doing wrong?
Are you trying to violate the Same-Origin Policy? If so, some recent
browser versions implement CORS that allow cross-origin requests under
certain conditions (server opt-in). I haven't checked but believe in
this case you could have a successful response with no status code.

multiselect ListBox getting selected items
I'm attempting to get multiple selected items from a ListBox My setup code is: final ListBox listBox = new ListBox(true); listBox.addItem(Item 1, 1); listBox.addItem(Item 2, 2); listBox.addItem(Item 3, 3); In the onClick event of a button on my panel I want to get the selected items. I have seen suggestions to iterate over all the items, calling the isItemSelected() method for each item to determine whether it’s selected. However I do not see any methods available on ListBox to get the list of items. Obviously I could add a listener to the listBox to capture when someone selects or unselects an item but there must be an easier way to get all of the selected items in a multiselect ListBox Regards, Dave -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

How to add Widget to a DOM element?
Is it possible to add a widget to a DOM element? I have some DOM structure that I need to directly create in code and I'd like to add a GWT widget as a child element of this DOM structure. Currently I'm using something like the following code to add a SuggestBox: domElement.appendChild(getSuggestBox().getElement()); While this code adds the underlying text input field to the DOM tree, the suggestion feature of the suggest box does not work. However, when I add the Widget directly as child element of another widget everything works fine. Does the call to getElement() somehow partition the Widget from the DOM element so that the DOM element is added without the Widget functionality? How can I add a Widget as child of a DOM element?

Re: Class in jar file used in another GWT application gives *Source not available* error when compiling
Try to compile it and I get the error copied below. I believe i need to inherit it, or need to specify the source path in Monkee.gwt.xml, but don't know how to do it. And the source code of the whole project I downloaded is a bit too complicated for me to understand, as I am still a beginner. Does anyone have an idea? I would guess you did forget to inherit the right module, because GWT Compiler only includes sourcecode for included GWT modules. You have to add the following line to your project .gwt.xml file: inherits name='org.gwt.advanced.Grid'/ Also, not being a GWT standard widget, can it still be declared in a UIBinder xml? Yes, this is possibly! You have to import the package of the widget using xml namespace declaration: ui:UiBinder xmlns:ui='urn:ui:com.google.gwt.uibinder' xmlns:g='urn:import:com.google.gwt.user.client.ui' xmlns:adv='urn:import:org.gwt.advanced.client.ui.widget' g:HTMLPanel !-- usage of datepicker -- adv:DatePicker ... / /g:HTMLPanel /ui:UiBinder If the datepicker has no no-args constructor then you have to supply a @UiFactory Method in your UiBinder class.

Memory Increase Using GWT RPC Calls
Hi,
I'm having some difficulties when making multiple GWT RPC calls from
within a GWT Timer.
I've run my example in a few different applications that monitor the
memory usage of the page and in all of them there is a constant
increase in the amount of memory after each call.
In the example all I am doing is scheduling a Timer to run every 5
seconds to call my service that simply returns a large string - around
250,000 characters (JSON formatted).
The memory increase seems to occur in IE7, IE8, FireFox Chrome.
Chrome's developer tools (Heap Snapshots profile) seems to suggest
that the increase is related to the strings I'm returning - I'm
assuming that by nulling the string that once the method finishes
running the garbage collector should clean it up but something must be
holding onto them, I just cant work out what!!
Any help would be greatly appreciated! Let me know if anyone requires
any extra information!
My entry point consists of the following code.
package com.imass.performancetesting.client;
import com.google.gwt.core.client.EntryPoint;
import com.google.gwt.core.client.GWT;
import com.google.gwt.user.client.Timer;
import com.google.gwt.user.client.rpc.AsyncCallback;
import com.imass.performancetesting.client.services.IVesselServices;
import
com.imass.performancetesting.client.services.IVesselServicesAsync;
public class PerformanceTestingEntryPoint implements EntryPoint {
/**
* Create a remote service proxy to talk to the server-side Vessel
service (Async).
*/
private IVesselServicesAsync rpcVesselServices =
GWT.create(IVesselServices.class);
public void onModuleLoad() {
new Timer() {
public void run() {
rpcVesselServices.getCurrentVessels(new
AsyncCallbackString() {
@Override
public void onFailure(Throwable arg0) {
// Show the RPC error message
to the user
GWT.log(arg0.getMessage());
}
@Override
public void onSuccess(String
resultString) {
resultString = null;
}
});
}
}.scheduleRepeating(5 * 1000);
}
}
Thanks in advance,
Jason.

Google Plugin for Eclipse 1.3 is now available
Hi everyone, I'm happy to announce the release of version 1.3 of the Google Plugin for Eclipse (http://code.google.com/eclipse). This release is designed to make life easier for developers using GWT and/or App Engine alongside third-party tools. For example, we've taken the pain out of using the plugin with projects built with the ever-popular Maven build system: no more ugly hacks or workarounds, or polluted WEB-INF/lib directories! We've even added a new FAQ dedicated to Maven usage: http://code.google.com/eclipse/docs/faq.html#gwt_with_maven. We've also worked hard to make sure the plugin works well with Dynamic Web projects in Eclipse for Java EE. See the following FAQ for details on this scenario: http://code.google.com/eclipse/docs/faq.html#gwt_in_eclipse_for_java_ee. In addition to improving third-party interoperability, we've also made the plugin more customizable and robust overall. Launch configurations now allow direct editing of generated command line arguments, and a new Errors/Warnings preference page lets you tweak the severity of any problem marker we create. We've also fixed a number of bugs related to App Engine ORM enhancement. To install the Google Plugin for Eclipse, you can find our update site URLs, along with detailed instructions, here: http://code.google.com/eclipse/docs/download.html If you're upgrading from a previous version of the plugin, you may want to consult our Upgrading the Plugin guide: http://code.google.com/eclipse/docs/updating_the_plugin.html *Note: If you installed the Google Plugin for Eclipse 1.3 Preview, be sure to remove the relevant subfolders from your eclipse/dropins folder before installing the official 1.3 release via the update site.* *Enhancements* - Configurable WAR directory to allow better integration with Eclipse for Java EE and projects built with Maven - Web Application launch configurations now display and allow editing of generated Program and VM arguments - Errors/Warnings preference page for customizing the severity of any generated problem marker - Projects can reference GWT/App Engine SDKs directly via JARs instead of through SDK library - GWT+App Engine projects automatically configured for optimal caching *Fixes* - GWT Issue 3583: Google Eclipse Plugin configuration is too strict - GWT Issue 3592: Eclipse plugin to add 'cache forever' configuration for new 'GWT + App Engine' projects - GWT Issue 3902: Allow users to configure the severity of problems reported by the eclipse plugin - App Engine Issue 1515: Eclipse plugin requires fixed location for war directory - App Engine Issue 2115: Using the @PersistenceAware annotation puts the Eclipse Enhancer in an Infinite Loop - App Engine Issue 1941: Plugin fails to enhance dependent classes on source level changes For a complete list of fixed issues, see the GWT issue tracker and App Engine issue tracker. We hope you enjoy using this new version of the Google Plugin for Eclipse for all your GWT/App Engine development needs! Let us know if you have questions or run into any issues. Thanks!

Re: Remote HTTP fetch from Server not working?
So I discovered that I need to add any extra libraries into /war/WEB-
INF/lib -- added apache httpclient, apache logging, and apache codec
jars.
Now I get this error ---
java.net.Socket is a restricted class. Please see the Google App
Engine developer's guide
But the gwt docs seem to suggest i can use anything i want on the
server side:
Tip: Although GWT translates Java into JavaScript for client-side
code, GWT does not meddle with your ability to run Java bytecode on
your server whatsoever. Server-side code doesn't need to be
translatable, so you're free to use any Java library you find useful.
Well this one would be useful... any ideas why it is a restricted
class? and what that means?
Anecdotally i saw that I should be able to use URLConnection? I guess
I'll try that.
Thanks!

[gwt-contrib] Re: Code Review Request: Fix flaxy MessageTransport test
I'm testing that if you try to use MessageTransport.executeRequestAsync(..) and the server side of the network has closed its input stream, then an exception will be thrown (an ExecutionException with an underlying cause of IllegalStateException). I don't think shutdownInput(..) would work, because it says that any input coming in will be silently discarded. I could probably use network.getClientSocket(..).shutdownOutput() to achieve the same effect, though I was really trying to test the case where the server side shut down the input stream.

Fix: = onUnload now uses ResizeAnimation to complete the hide process if the PopupPanel isn't already hidden. While the fix seems trivial, this bug actually revealed a few problems that can lead to invalid states. First of all, prior to this patch, calling hide() would actually call setState() twice (once in hide, once in onUnload).

+#How code is loaded on demand in the cross-site linker
+
+= Introduction =
+
+The cross-site linker has two challenges for runAsync. First, the code
can't be loaded with XHR, because of the Some Origin Policy. Second, the
code cannot be loaded at the top level of any iframe, but instead must be
inserted into an inner scope of a function.
+
+This page describes the general strategy used. The precise details, e.g.
the label names, are subject to change.
+
+= Inserting code into a function =
+
+In the initial code download, GWT code is wrapped in a function, and that
function exports an installCode function as an expando off of the
function itself:
+{{{
+function my_gwt_app() {
+ var jslink = new Object();
+ my_gwt_ap.installCode = function(code) {
+var install = new Function(jslink, code);
+install(jslink);
+ }
+ // rest of initial code
+}
+}}}
+
+Since the scope of each new Function call is different, all cross-island
references must go through the jslink object. New definitions must be
installed like this:
+{{{
+my_gwt_app.installCode(jslink.foo = function foo() { })
+}}}
+
+Uses of an identifier from another island look like this:
+{{{
+my_gwt_app.installCode(jslink.foo();)
+}}}
+
+The GWT compiler includes an optional pass that is controlled by the
configuration parameter `compiler.predeclare.cross.island.references`.
It's false by default, but individual linkers can turn it on when needed.
Here's how the cross-site linker itself turns on this pass:
+{{{
+set-property name=compiler.predeclare.cross.island.references
value=true
+ when-linker-added name=xs /
+/set-property
+}}}
+
+
+= Cross-Site code load =
+
+Cross-site code is loaded using class CrossLiteLoadingStrategy.
+
+The general technique is like JSONP. Script tags aren't subject to the
Same Origin Policy, so they can be used to download the code. The content
downloaded via the script tag has been wrapped as follows:
+{{{
+__MODULE_FUNCTION__['runAsyncCallback3']('here is the downloaded code')
+}}}
+
+Before inserting the script tag, CrossSiteLoadingStrategy must insert a
callback to handle that code. The callback updates the runAsync book
keeping and then uses the installCode function to actually load the code.
+
+= Detecting download errors =
+
+Detecting download errors with XHR is straightforward, but trickier for
script tags. At the time of writing, the implementation uses all of the
following attributes on the created script tag: onerror, onload, and
onreadystatechange. Additionally, onreadystatechange does not indicate
whether the download actually succeeded or not. Thus, the callbacks are
all tolerant of bad code. Correspondingly, LoadErrorHandler is now called
LoadFinishedHandler.
+
+= Retry =
+
+Retrying failed downloads is also tricky on some browsers. There appears
to be a heuristic in some browsers that if a script tag download for a URL
fails three times, then no further downloads of that URL will be
attempted. To work around this, CrossSiteLoadingStrategy adds a serial
number to each request. Instead of requesting deferredjs/123.cache.js, it
uses deferredjs/123.cache.js?serial=0 .

Re: [gwt-contrib] Support runAsync with the cross-site linker.
Something is screwy with riedvelt, and I can't leave a comment on XSTemplate.js My comment isn't really about your patch in particular, but the patterns we are using in the linker templates. I wish that stanzas of code common to many linkers, like the calling of __gwtStatsEvent() could be extracted and put into the template with variable substitution. For example, adding the sessionId field to the event works fine here, but there are several linkers outside of GWT that will need to be updated to get the same fix. -Eric.

[gwt-contrib] DOMImpl#eventGetTypeInt returns NULL for unknown event types
Reviewers: Dan Rice,
Description:
DOMImpl#eventGetTypeInt returns NULL for unknown event types instead of
an int, resulting in an exception.
Fix:
===
Added default case that returns -1 and updated JavaDoc.
Testing:
Added a unit test.

[gwt-contrib] Avira and HTML/CryptedGen (again)
We started getting reports of the HTML/Crypted.Gen being detected in our Chrome extension again. I've managed to reproduce it - the signature seems to be the exact set of strings they use: .fromCharCode .charCodeAt nodeValue for 0,0,0,0,0,0 Math.min I kid you not - this is their signature for an encrypted JS virus. I can't seem to remove a single character from any of these tokens without turning it from a dangerous virus to a harmless bit of JS. Order doesn't seem to be important (although I haven't experimented with this that much). I think I'll be able to work around this by replacing any sequence of six zeros separated by commas with the sequence 0,0,0,[space]0,0,0.

Surely they could at least change the warning to say potentially dangerous JS or something rather than declaring it a virus. This is pretty unbelievable to me as well. I imagine that the process involved someone finding a mutating JS virus, found six strings that it always contained, put them in and figured that it was safe after surfing around for a bit without any false positives. After experimenting a bit further, I discovered that nodeValue is actually matching case insensitively for eval (which makes a little more sense). This means that the signature is something like for eval .fromcharcode .charcodeat math.min 0,0,0,0,0,0 This probably will likely affect a significant number GWT applications that use RPC. Avira seems to check files ending in .js* and .html* for this pattern. I verified that the scanner intercepts these patterns in HTTP traffic and detects them in IE cache files. There might be some negative patterns as well: Avira doesn't block my message in the Google Groups web interface, but it does block it when viewing the raw message source.

Even better: it turns out that if you put the string google anywhere in the file matching CryptedGen, it no longer matches the heuristic. I imagine that it would pick up the string from the class metadata for those not using -XdisableClassMetadata. So this is a virus: for eval .fromcharcode .charcodeat math.min 0,0,0,0,0,0 And this is not: google for eval .fromcharcode .charcodeat math.min 0,0,0,0,0,0 The easiest solution for us seems to be putting the string Google Web Toolkit in a comment in our header.
