Re: Building a GWT project in Eclipse 2019-03+ with Java 11.
> Our current workflow is using SuperDevMode + Jetty and I'd like to provide similar experience to our team. I had a similar concern, as before we both SuperDevMode and the app in the same Java process. After the switch, we need to start the codeserver and then the app, via Tomcat. But, things went well, because: 1. You don't have to start your app in the build tool and connect remotely. The codeserver will write its files to the same place as the regular compilation would, and you can start your app in a debug session in Eclipse. We're using the built-in Tomcat server (with Eclipse WTP). Just make sure that after starting the codeserver, you have your workspace refreshed, so Eclipse can publish it accordingly (that's why we wrote the script, as mentioned in the previous post) 2. Starting the codeserver is actually slower than the app (at least for us, and the app is huge). When you debug the app, you'll eventually do an incompatible change that needs to restart the app. When using the codeserver as a separated process, it stays there, in the same place, even when you restart the app. IMO, this ended up being more productive than the previous setup 3.

Re: Building a GWT project in Eclipse 2019-03+ with Java 11.
We started using GWT in our project in 2009 (GWT 1.5.0!)
When we moved from Maven to Gradle in 2020 (one of the best decisions ever,
because the project is complex, has a lot of code generation and Gradle's
skipping of already executed tasks is a must - it was unbearable with
Maven), we've also dropped the GWT Eclipse plugin altogether.
Also, we don't use a GWT plugin for Gradle either: instead, we just run
either GWT codeserver or compiler via their main classes, setting up the
classpath correctly.
To start with, as we already had multiple modules in the build system (api
/ impl / web, etc), we've split the GWT classes to a new module (no longer
the web project).
Attached in this post is the anonymized and stripped down build.gradle file
for the gwt module.
Finally, for us to be productive again in Eclipse, we've written a script
that does the following:
1. Delete the destination's nocache.js file
2. Starts the code server via gradle, redirecting the output to a file
3. Sleeps until the nocache.js file exists again
4. Write the PID of the gradle process to a file
We run this from an Eclipse external tool, and have the tool's refresh
option to refresh the web's project output dir. This way the publishing
works flawlessly in Eclipse with a Tomcat server.
We've also created other 2 similar scripts / Eclipse tools: one to stop the
codeserver (kill the process with the PID indicated in the file) and
another one to show the codeserver log (tail -f1000 -n in the output file).
We'll never look back to neither the Eclipse plugin (which did many other
things we don't use) nor to a Gradle plugin (which were mostly written once
and abandoned, and Gradle evolves fast, introducing breaking changes, and
that broke the project more than once).

Re: New Article "10 Best Java Frameworks to Use in 2021"
We ended up using no plugins for GWT with Gradle. Even if there are some,
none of them fit well.
Luckily, GWT compiler has a nice CLI, so...
Also, we make the gwt a subproject, as we don't use GWT RPC anyway. This
helps keeping gwt-dev out of any runtime classpath!!!
Below is a trimmed version (not sure it even compiles, and it is the
build.gradle for a subproject) of the build.gradle file for reference, for
both compilation (even with a system flag to compile only the dev module)

Re: Is GWT 3.0 /GWT 2.9 dead?
It is great to know we can use the snapshot with support for Java 11 already! Unfortunately, except for the GWT team and those that follow the project closely, it looks like GWT is stuck at the 2.8.2 release 2.5 years ago, because the GWT official website contains no information on this. Maybe it would be good to put some text in the home page pointing to this. I'm surely much more optimistic now that I know there is an usable updated version. Great work, guys!

Re: Is GWT 3.0 /GWT 2.9 dead?
It has always been said that GWT is active when similar questions are asked in the forum. However, given that the last version, 2.8.2, was released on Oct 19, 2017 and was a bugfix for the 2.8.0 version, released on Oct 20, 2016, I can't see it as "active". At least it smells bad! Even the 1.0 release of Elemental can't be used, because it requires newer components than the pre-packaged version. It is a sad thing, because I work on a large project using GWT since its 1.5.0 version, and our project is actively developed and still evolving. I hope GWT 2.9 is out "soon", because we're planning to switch to Java 11 in the coming months, and it would be a burden to maintain a separated Java version only for the frontend part (been there, done that with Java 8). The fact is that since Google left the project, things are way too slow. Understandable, as it is based on best effor from the brave developers, but still disheartening. Still, I don't loose hope that GWT will be still maintained.

GWT 2.8.0-rc1 and closure compiler
I've always used the closure compiler with past versions (even with 2.8.0-beta1, which we have used in production already). Now, to my surprise, it is no longer supported in GWT 2.8.0-rc1, as there's no mention to it in the release notes (http://www.gwtproject.org/release-notes.html). Now the compiler no longer supports the old closure compiler option, but has a new -X[no]closureFormattedOutput option. I'm guessing closure compiler is no longer integrated in GWT, but it still has the option to format for closure to a later (manual) usage of closure compiler. I'm using the gwt-maven-plugin, which still uses beta1, but explicitly changing its dependencies to 2.8.0-rc1 for gwt-user, gwt-dev and gwt-codeserver artifacts, making it usable already for rc1. I can't, however, pass the new option (I think there's no way to pass arbitrary compiler arguments with gwt-maven-plugin) until the maven plugin is updated. What are the new instructions to keep using closure compiler? -- You received this message because you are subscribed to the Google Groups "GWT Users" group.

Generic way to acess a entityProxy properties
Good night.
As i have a dozen entities in my system, and pretty much the same layout
for their display, i'm trying to create a generic panel, wich could receive
any entityProxy and a set of parameters, those parameters would be the path
of the attribute i'm trying to display.
My ideas was to, from the proxy, read the value based on a path, like the
"with" from the request context.
Something like this:
Person has a Address
Address has a street_name
String name = person.getAttribute("address.streetName");
Has someone ever did something similar?

Re: Next release
"classpath conflict is generally not a valid reason, because the part of GWT that includes Jetty is not concerned about the server side of the applications" Unless you run [Super]DevMode, which runs both in a single JVM, then it is a pain. There are other libs which are bundled in GWT jars, causing some inconveniences too, like IMHO, saying to run with -noserver is not a perfect solution either, because it complicates things, requiring 2 jvms, and don't playing well with RPC and security policies. Having most of people (if not all) using either an IDE plugin or Maven, which can manage the classpath, I don't see a reason to bundle (very old) 3rd party classes in the GTW jar.

GWT 2.8 update
I'd like to ask for an update on the planning for 2.8 release. Are there still many missing functionality? What is the tentative release schedule? I'm avid to change our project source level to Java 8, but I'm not confident in using the SNAPSHOT in a release version of our app. Any chances it will be out still in August?

Re: Static vs dynamic String internationalization
That, of course, depends on the application requirement. I work on a very large app which is not (only) used by ourselves, but by other organizations. And on each organization, administrators can change translations on the fly - just a F5 or logout / login away. In this scenario, of course, there is no choice. We even created a custom translations loading mechanism that efficiently use the browser cache and load translations in parts, as there are more than 4k keys, as we don't want all them to be always downloaded. Each page (it all started in GWT 1.5, before GWT places existed) knows which translation part it needs, so we guarantee to load the required translations before showing the page. But, I agree, it is a very specific requirement. Maybe 99% of the applications are fine with static internationalization. We're part of the other 1%. -- Luis Em segunda-feira, 23 de fevereiro de 2015 19:33:34 UTC-3, Jens escreveu: - The big advantage of dynamic internationalization to me, is that I can store my translations in a database, and update texts without the need of stopping servers to deploy a new compiled version of my application. Not sure if its that big of an advantage. IMHO translations rarely change and the number of supported languages is probably already known upfront and does not change often either. Also if done right, updating an app does not cause any downtime especially if only translations have changed or languages have been added. The worst case is that a user gets a message App has been updated and needs to be reloaded. If your app uses history tokens (e.g. GWT places) then reloading the current place doesn't really hurt. -- J. -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: Current state of one .js file per module
Ok, I'll try to use separated servers for code server and server side. Regarding the monolithic .js, in GWT 1.6 it was impossible to debug in both Chrome and Firefox - they both crashed, and I always suspected that the js / sourcemap file were too big. Now with GWT 2.7 I can debug normally in Chrome (didn't try in Firefox yet). Still I guess it could be faster to debug using separated .js files. However, as this is no longer GWT's goal, ok. At least now debugging in Chrome is usable, and I no longer need that old version of Firefox 26 which still runs the classic dev mode. Em sexta-feira, 5 de dezembro de 2014 12h31min41s UTC-2, Jens escreveu: Separate compilation mentioned in your linked issue has been reworked into incremental per file compilation what you have now with GWT 2.7. The benefit is that people do not have to refactor their applications into multiple modules to get the benefit of faster recompiles in SDM. Regarding CodeServer restarts: With current GWT master branch, a restart of the CodeServer reuses the caches from the last compile which reduces the startup time of CodeServer significantly. Keep in mind that you do not have to use the DevMode class to start the embedded Jetty + Code Server process. You can also split these processes so you do not have to restart SDM CodeServer if you do a server side change. DevMode -noserver or launching CodeServer directly only starts the SDM code server. Then you can provide your own application server or actually start DevMode -nosuperdevmode which does start classic DevMode but also the embedded Jetty for your server side code.

Current state of one .js file per module
Hi. I created an issue several months ago - https://code.google.com/p/google-web-toolkit/issues/detail?id=8581[1] to split up generated .js. The answer was that a .js file, with its corresponding source map, would be generated per module. I'm analyzing now (with GWT 2.7.0) the output, and I still have 1 single monolithic, .js file and a single source map. Has this subject been aborted, postponed, or just not enabled by default? My project is big. It would be great if the files were split per module, as commented in the issue. I'd love to improve this, and reduce the timings on it. Specially between runs - sometimes small incompatible debug changes in server side forces a restart - and a new compilation. In this case, the reload button doesn't help, as the JVM is inconsistent anyway. Just for the record, here's the compilation log for the project (the real module was changed to package.Project).

Re: add mobile version to existing GWT app?
ok, but this leads me to the question, why we don't use REST/JSON right from the beginning? Isn't it a potential option for nearly any web application today to be complemented by a mobile version some day? I work in a large project which started in 2008, but was not full time back then, and only about, say 2011 got real priority. We started with the just released GWT 1.5, and there was not too many things to choose as today. Now we have a mobile app, and we have 2 entry point servlets: one to handle GWT RPC, and another one which exposes services in a rpc-like with json (not REST, as we don't want to maintain 2 APIs - it is just mirrored using Jackson). Not to say that we have A LOT of generated code to handle RPC. The current total size of our app is 3.3MB, where 6.4MB is for generated code for RPC (according to the compile report). Of course we use code splitting, but we're currently struggling on reducing the sizes. Currently, we have 975KB of initial download, 370KB of leftover and 9 split points (432KB max). If I'd start the project today, I'd just use plain REST / JSON for both the desktop and mobile versions. -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

ok, but this leads me to the question, why we don't use REST/JSON right from the beginning? At the beginning of a project you usually know what you want to do. So if you want native clients for different platforms then you will start with some sort of REST/JSON or protobuff/thrift/... backend.

Re: Using SuperDevMode with code splitting
Well, I hope this will be sorted out, because debugging on a monolithic code of hundreds of thousands lines of code simply doesn't work - the browser hangs as expected. There's the following statement on http://www.gwtproject.org/articles/superdevmode.html : Currently, Super Dev Mode doesn't work on some very large GWT apps where classic Dev Mode works. This is probably because of the generated JS code size, but I'm sure this will be worked out. Otherwise, GWT will die in the short-mid term, because browser plugin based debugging is mostly dead (already in FF, soon in Chrome).

the same problem but i didn't find anything.
I've got class AbstractDialog that extends DialogBox with some
standart buttons like OK CANCEL that are bound by UiBinder. I've got
another class that extends AbstractDialog with another declarative xml
file, that contains only the main content of that DialogBox.
When am trying to lunch application i got this error:
Rebinding package.classUiBinder
Invoking com.google.gwt.dev.javac.StandardGeneratorContext@a51c3c
Method 'ok' can not be bound. You probably missed
ui:field='okButton' in the template.
Method ok and UiHandler for button okVutton is declared in
AbstractDialog. From class that extends AbstractDialog the UiField is
not visible. Am i doing something wrong or i just didnt saw any
information that you can not extends an object tha got his own
UiBinder and extended class got their own UiBinder as well.
My code:
AbstractDialogBox.java
public abstract class AbstractDialogBox extends DialogBox
{
private static AbstractDialogBoxUiBinder uiBinder = GWT.create
(AbstractDialogBoxUiBinder.class);
interface AbstractDialogBoxUiBinder extends UiBinderWidget,
AbstractDialogBox
{
}
@UiField Button okButton;
@UiField Button cancelButton;
@UiField Label emptyLabel;
@UiField VerticalPanel main;
public AbstractDialogBox()
{
setWidget(uiBinder.createAndBindUi(this));
setStyleName(oe-DialogBox);
okButton.setText(OK);
cancelButton.setText(CANCEL);
}
public void setContent(Widget content)
{
main.add(content);
}
@UiHandler(okButton)
void ok(ClickEvent e)
{
onOK();
}
@UiHandler(cancelButton)
void cancel(ClickEvent e)
{
onCancel();
}
public void keyPress(KeyPressEvent event)
{
if (event.getCharCode() == 13)
onOK();
else if (event.getCharCode() == 27)
onCancel();
}
public abstract void onOK();
public abstract void onCancel();

Re: How to share classes between two different modules with two different pages
i think that you can make a new module for the classes you want use in other two, and inherit it.

Re: Hosting issue
Hi Nitheesh, my assumptions of the problem is as below. 1. you have created a GWT project with RPC and connect database from MySQL. 2. if you deploy the GWT War files in Tomcat which is installed in your local machine,it is working properly. 3. if you deploy in tomcat which is installed in any of the shared webhosting server or VPS,the RPC is not working.

GWT and Hibernate
Hi, I started to use GWT with Google App Engine (GAE) and did all the pages and navigation between them. I also have another project when I use hibernate. So, I have the following scenario: GWT as presentation layer and this other project as business logic. I use RPC to make the calls betweend them. My point is: I tried a simple transaction to validate the user login and the project returns the following error: Error while registering Oracle JDBC Diagnosability MBean. I have search on the net about this error and I have found that I cannot use hibernate and GAE together. So I disabled the GAE at my GWT project properties and the page stops loading. Question: is there a way to use hibernate only to make simply queries? I don't want to traffic hibernate objects between the projects. I only need to make the query, process the result to native objects and send them back to the GWT project. -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Mouse click not working on ListGrid
I have a strange problem and i am sure it is just simple mistake of
some kind but i cant really find it and i dont really know what to
search.
I create a new window with VerticalPanel in it. Inside this Vertical
Panel i put TabSet with SelectItem component. The problem is that
clicking on drop down is not working. Same situation is when i put
ListGrid inside, RecordClickHandler and RecordDoubleClickHandler are
not working at all (but RowContextClickHandler works).
public class Sample implements EntryPoint {
public void onModuleLoad() {
//Without verticalPanel - works !
SelectItem s1 = new SelectItem();
s1.setTitle(Test List);
s1.setMultiple(true);
s1.setMultipleAppearance(MultipleAppearance.PICKLIST);
s1.setValueMap(a, b, c);
DynamicForm c1 = new DynamicForm();
c1.setItems(s1);
TabSet topTabSet = new TabSet();
topTabSet.setTabBarPosition(Side.TOP);
topTabSet.setWidth(800);
topTabSet.setHeight(150);
Tab t1 = new Tab(Tab1);
Tab t2 = new Tab(Tab2);
t2.setPane(c1);
topTabSet.addTab(t1);
topTabSet.addTab(t2);
Window window2 = new Window();

Re: com.google.gwt.user.client.rpc.IncompatibleRemoteServiceException
Yes, it has a zero argument constructor. As I said, once I recompile, undeploy and deploy again, the problem goes away. I'm using Eclipse and deploy an EAR in Glasfish v3. This EAR contains an EJB jar, a GWT WAR and other jars. I noted that IncompatibleRemoteServiceException sometimes raises up after I change EJB code. It's not enough with undeploy and deploy. I also have to recompile to get everything working. Maybe it is a problem with packaging. Maybe the RPC generated security files are not getting into the EAR properly. Any idea about how to solve this? Any idea about how to disable that security feature? Thanks.

com.google.gwt.user.client.rpc.IncompatibleRemoteServiceException
Hi, I'm having an IncompatibleRemoteServiceException very often in development mode. It looks like it raises every time I change my EJB server code, which is in a project referenced by my GWT project. Error: com.google.gwt.user.client.rpc.IncompatibleRemoteServiceException: Type com.example.MyDTO was not assignable to 'com.google.gwt.user.client.rpc.IsSerializable' and did not have a custom field serializer. For security purposes, this type will not be deserialized. MyDTO implements Serializable, and it is not the EJB code I'm changing. The EJB references this DTO. If I compile my GWT project again, the problem goes away... for a while. This problem is causing a decrease in my productivity as I have to compile and wait a minute every time this problem shows up. Any idea about how to solve this? As a workaround, does anyone know how to disable this security feature while I'm in development mode?

Re: Ejb and gwt..?!
Yes, you can do that. I tried it a few days ago and it worked.
In my case, I implemented a servlet which would act as a bridge
between RPC services and an EJB.
I based on this : http://dobesland.wordpress.com/2007/08/01/gwt-to-ejb-bridging/
Basiically, don’t implement the GWT service’s interface in your
RemoteServiceServlet. I don't remember the code exactly, but you can
inject EJB and override processCall() like this:
@EJB
TheEjb theEjb
public String processCall(String payload) throws
SerializationException {
try {
RPCRequest rpcRequest = RPC.decodeRequest(payload, theEjb);
return RPC.invokeAndEncodeResponse(theEJB, rpcRequest.getMethod(),

Re: Handling too many locales in a large scale real life app
just in case...
after trying the EPFE plugin that Dolber posted (btw, thanks for the
tip) I found out that the project was put on ice
(source:
http://epfe.sourceforge.net/index.php?option=com_contentview=sectionlayout=blogid=1Itemid=3)
their own authors point out to another plugin, Eclipse ResourceBundle
Editor, which can be found here:
http://sourceforge.net/projects/eclipse-rbe/
this plugin is more complete than EPFE, and we're considering using
it, even tho it has been incorporated by Eclipse Babel project
http://www.eclipse.org/babel/
Babel promised an editor, but so far has not delivered it

Handling too many locales in a large scale real life app
So, in my company we face a problem where we have too many properties files to handle, and they are all large, every now and then one properties is left outdated and is missing some translations. I wanna know if there's an easy way (app, library, anything...) to deal with them besides a strict process of updating them all the time. One coworker suggested that we should make an app to generate these properties files from a database, but before we started working on that, I wanted to post here in case someone knows a solution.

You can do that on the client side. Although you don't have
reflections, you can have a helper class which can do that work for
you. That helper class could have a big if, else if, else if clause
and compare classes using instance.getClass(). Every time you add a
new class you want to use reflections with, you can add a new else if

Re: Instantiate composite on the server side
Correction... If you want to know the type of the created object, It's
almost type safe. :P If you are alright by knowing it's a Widget,
it's type-safe. Here's a tidier version of the code:
Almost type-safe:
public class Reflector {
@SuppressWarnings(unchecked)
public static T T createInstance(ClassT theClass) {
if (theClass == TextBox.class)
return (T)new TextBox();
else if (theClass == Button.class)
return (T)new Button();
else
throw new RuntimeException();
}
}
Type-safe:
public class Reflector {
public static T extends Widget Widget createInstance(ClassT
theClass) {
if (theClass == TextBox.class)
return new TextBox();
else if (theClass == Button.class)
return new Button();
else
throw new RuntimeException();
}
}

put the necessary jar files in Reference Library, But I still have
several things error. Could you tell me what I miss? I put the error
message in the line directly.
Thank you

IE8 problem when using Singleton and DockLayoutPanel
Hi everyone,
I have a Welcome Screen which is made by hand from the entry point.
On the other side, I have Widget named Main which uses the Singleton
pattern: this Widget encapsulates the application funcionality and
there should be only one instance in the application. This Widget is a
composite over a DockLayoutPanel, which has north, west and center
panels. The unit used to define the size of these panels is EM.
The problem raises in IE8. If I use the Widget the first time I call
Main.getInstance(), everything is fine. However, if I use it (add it
to RootLayoutPanel) after the first time, IE8 only shows the center
panel.
If I use PX insted of EM, everything works fine.
Here is the code:
//BugTest.java
package com.bugtest.clearadd.client;
import com.google.gwt.core.client.EntryPoint;
import com.google.gwt.event.dom.client.ClickEvent;
import com.google.gwt.event.dom.client.ClickHandler;

import com.google.gwt.user.client.ui.RootLayoutPanel;
import com.google.gwt.user.client.ui.RootPanel;
public class BugTest implements EntryPoint {
@Override
public void onModuleLoad() {
Button prefetchButton = new Button(Prefetch!);
prefetchButton.addClickHandler(new ClickHandler() {
@Override
public void onClick(ClickEvent event) {
//Invoke the function but do nothing.
Main.getInstance();
PopupPanel popupPanel = new PopupPanel(true);
popupPanel.setWidget(new Label(Prefetching
finished!));
popupPanel.center();
}
});
Button switchButton = new Button(Switch!);
switchButton.addClickHandler(new ClickHandler() {
@Override
public void onClick(ClickEvent event) {
//Here I use the result if the function
Main result = Main.getInstance();
RootPanel.get().clear();
RootLayoutPanel.get().add(result);
}
});
FlowPanel flowPanel = new FlowPanel();
flowPanel.add(new Label(Bug test!));
flowPanel.add(prefetchButton);
flowPanel.add(switchButton);
RootPanel.get().add(flowPanel);
}
}

}
return instance;
}

DockLayoutPanel dockLayoutPanel = new
DockLayoutPanel(Unit.EM);
dockLayoutPanel.addNorth(new Label(North!), 7);
dockLayoutPanel.addWest(new Label(West!), 15);
dockLayoutPanel.add(new Label(Center! :D));
initWidget(dockLayoutPanel);
}
}
Is it a bug or I am just missing something?
I posted this problem in another place, but now I realize that I
should have posted here first. :P Anyway, I haven't received any
comment on that post, so that's why I'm here.
This problem showed up when I was trying to use code splitting. I was
using the Async Provider pattern, but the singleton pattern is a
simplified version which has the same issue. The first call to
Main.getInstance() correspond to a prefetch when I know there's little
network activity.
Thanks in advance.

Centering a panel inside a ScrollPanel
Is there any way to center a panel inside a ScrollPanel? When I have to center a panel inside any other panel that is not a ScrollPanel, I use CSS: Parent position: relative; Child position: absolute; left: 50%; top: 50%; margin-left: -(panelWidth/2) margin-top: -(panelHeight/2) However, this is not working inside a ScrollPanel. Specifically, neither Firefox nor IE uses the top: 50% property. Any idea? Thanks in advance. -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

This has nothing to do with GWT. Inputs of type file cannot be styled using normal CSS. This has been an issue for years, and I don't know if it will ever have a standard solution.

I already did this technique but the fact is my browse button has 2

technique, the over mouseevent can't be use with the browse button

Maybe someone will have an idea to figure it out with this solution or
another, but anyway, thanks for your time, I appreciate.

Limiting serializable types in RPC
Is there a way (it would be nice if there were one) to exclude types from RPC? Here's the concrete use case: In our project, the RemoteService interfaces are defined in a separate project as the web layer. And all methods / parameters use the Java best practices: always reference collections by it's interface. However, having a method to return CollectionString, for example, generates code to handle Vector, ArrayList, LinkedList, HashSet, LinkedHashSet... As interfaces are in a separated project, and it would be messy and make maintenance harder to change all interfaces to a given implementation... If I know I ALWAYS return ArrayLists or HashSets, is there a way to blacklist other types so code to handle all other types wouldn't get in our generated javascript? -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: Deprecation warning in all RPCs dealing with collections on GWT 2.0 RC2
This issue is still present on GWT 2.0 final. I've made some tests: creating a new GWT project with Collections in RPC methods don't result in such code being inserted in the generated JavaScript. The point is: our project is quite huge, but I can confirm that there are no occurrences of any of the ListenerCollections mentioned. Compiling with -compileReport shows as only references for those collections the RPC generated TypeSerializers and FieldSerializers. Could someone, please, explain how to get rid of those unwanted (and unused) collections in the generated code? PS: I've read some time ago that all this deprecated code would be removed in GWT 2. It's even in the source code that it would be removed. Why it wasn't?!? If it's for people using the old event listeners, I can assure that I've migrated from GWT 1.5 to 1.7 in 1,5 days. When I first replaced Listeners by Handlers I had 600+ compilation errors. Just changed the inner classes and everything worked. And better. Not to count having to rearrange the app to use the war directory. So I think this is no excuse for keeping deprecated code, as I think that 99% of the GWT users are working in a code base the same size or smaller than ours. -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: Deprecation warning in all RPCs dealing with collections on GWT 2.0 RC2
Just found the answer, and luckily in my case it was simple to solve I have a subtype of ListT called PageImplT, which had another ListT containing the page items, plus the total count. Then (and I think is a problem in GWT compiler), the compiler resolves FocusListenerCollection, which extends ArrayListFocusListener to be a subclass of ListT. As a result, ALL occurrences of Collection of anything in any RPC method, by having PageImpl as a subclass of collection, had added those ListenerCollections as possible result types, generated code to handle them (50k in my case) and issued the warnings. The solution (in better words: hack) was to change PageImpl to not have a List of page items, but a LinkedList (it then converts the receiving list into a LinkedList, which is even a penalty in my case). As no ListenerCollection extends LinkedList, the problem is gone. Ah, I also had an RPC which result type was ListListString. The same problem. As it was just for testing, I changed it to ListString[] . But I'd really want to hear from a GWT dev if this is not a bug in the compiler...

Re: Deprecation warning in all RPCs dealing with collections on GWT 2.0 RC2
In fact, there is a very easy way to reproduce it: Just create a RPC method which returns ListListString. You'll see references for those deprecated collections. On 11 dez, 17:39, Luis Fernando Planella Gonzalez lfpg@gmail.com wrote: Just found the answer, and luckily in my case it was simple to solve I have a subtype of ListT called PageImplT, which had another ListT containing the page items, plus the total count. Then (and I think is a problem in GWT compiler), the compiler resolves FocusListenerCollection, which extends ArrayListFocusListener to be a subclass of ListT. As a result, ALL occurrences of Collection of anything in any RPC method, by having PageImpl as a subclass of collection, had added those ListenerCollections as possible result types, generated code to handle them (50k in my case) and issued the warnings. The solution (in better words: hack) was to change PageImpl to not have a List of page items, but a LinkedList (it then converts the receiving list into a LinkedList, which is even a penalty in my case). As no ListenerCollection extends LinkedList, the problem is gone. Ah, I also had an RPC which result type was ListListString. The same problem. As it was just for testing, I changed it to ListString[] . But I'd really want to hear from a GWT dev if this is not a bug in the compiler...

Re: how large of your GWT compiled code? My one is 850K
Sorry for taking so long to answer, but I haven't seen your post before. We haven't yet done any larger performance test, but it is very acceptable. Yesterday, in a first no-brainer attempt of GWT.runAsync(), I've managed to get a 650K initial download and then a separate file per module (for now, modules varies from few K to 180K). I'll still try to reduce both the initial download and the modules. It does takes more time to compile now. That's an issue to me as I can't use the built-in server: we use EJB, so there's an external server. Whenever anything changes in RPC (params, methods, even classes) we need to recompile :-/ I still didn't implement gzip compression, but hope things can get much better... Ah, about IE6: as our app is targeted to late 2010, we won't support IE6 \o/ -- Luis Fernando Planella Gonzalez On 16 nov, 12:19, Bakul bakul.ku...@gmail.com wrote: Hi, Our app, 50 -55 % done so far, for one browser is nearly 1.6 MB without gzip.
