Re: GWT Developer Plugin works only sometimes

[cromoteca]

Truth is my application *works* with 2.0rc. It's just that most of the
times dev mode is not able to start and I need to try again until it
starts correctly.

I also forgot to mention that Firefox crashes frequently since I
installed the dev plugin. I really cannot believe that this release
has been tagged as "release candidate". It's a beta at best.

Re: SOP and GWT 1.7

[oleberre]

Hi Thomas.

Thanks a lot for the information.
So, I did what you adviced me i.e. adding the linker option in the
module.
As you suspected, it does not generate a nocache.js with the xs suffix
but the usual file with the right
version.

However, trying to load my module, I get the following message from
jetty :

Cross-site hosted mode not yet implemented. See issue
http://code.google.com/p/google-web-toolkit/issues/detail?id=2079

So, as far as I understood, there is a problem only with hosted mode,
but it should be ok once deployed.
So, I deployed everything on google app engine and try to load the
script from a different page.

I tried two ways but only one worked. So, if I simply add the
following line anywhere in the code :



everything works fine.

But if I try to include the script as following :


var url = "http://domain.appspot.com/module/module.nocache.js";;
var script = document.createElement("script");
script.setAttribute("src", url);
script.setAttribute("type", "text/javascript");
document.getElementsByTagName("head")[0].appendChild(script);



It does not work properly. From the firefox error console, I have the
following error

   Error: __gwt_stylesLoaded is not defined


Anyway, I guess the first method is the one recommended and easier to
use.
Or maybe shall I raised an issue on that ?

Regards.
Olivier.

Can't debug in eclipse in development mode with GWT 2.0 RC1

[Youen]

Hi,

I'm testing GTW 2.0 RC1 and I don't know how to debug (in eclipse)
when i am in development mode.

I set some breakpoints, I run in eclipse debug mode and I use firefox
3.5, but it seems that the breakpoints are not catch.

Does someone make it work or am I missing someting ?

Regards,

You don't need any "page" actually (though you might *want* pages),
and your challenge doesn't talk about "bookmarkability" (well, because
you say it should use HTTP POST, I believe you're "modifying a
resource's state" and therefore the URL for, e.g., "page 2" is the
same whichever the value you entered in "page 1"; ...and now that I
looked at your swf1's sample, it seems this really is the case: the
URL doesn't change between "pages").

This leads me to say that your "challenge" is completely "not web-
style", it reminds me of JSF (don't ask me what I think of it, I can
become angry quite quickly).

Instead of focusing on "page flows" (why are there so many frameworks
doing such a shitty thing?), (learn REST if needed and then:) focus on
resources and their states, moving application state to the client
(and therefore building a stateless server, where you don't even need
"sessions"), etc.

Re: Anyone using soafaces for client server communication ?

[R.Domingo]

Hi Sam,

Thank you for responding, I really like to get soafaces up and
running.

The jars I'm using are:
jettison-1.0.1.jar
soafaces-services-client-2.4.2.jar
soafaces-services-servlet-nomule-2.4.2.jar
xstream-1.2.2.jar

In my hosted browser at least:
- onUniversalClientSuccess is triggered

But when building a jar and depoying in tomcat:
- onFailure is triggered
I couldn't find any error message, the exception thrown in onFailure
doesn't have a message in it.

Any ideas ?
Or is there any change you could post an (maven2 enabled) example
using gwt and soafaces ?

RTL

[Jaber]

Hi,

i think i did the part of i18n in terms of labels and texts, but what
about the page direction, how can i switch between RTL and LTR, i have
seen the way on which showcase project was built, which is depending
on css switching the thing i can see a little bit uncomfortable, so
what other options do i have, and does the layout of my page(the
compostion of components in panel) effected or effects this,

Re: Design Patterns

[Martin Trummer]

maybe you should ask a more detailed question

the GWT stuff is just an implementation of the corresponding pattern
with the same name
you'll find plenty of explanations for the patterns when you google
for them
or look it up in wiki
http://en.wikipedia.org/wiki/Command_pattern

I don't know what more one could say about this..

Re: GWT 2.0 Javascript IE Crash

I raised an issue for this a few days ago.

I have just worked out what causing it. Its a mistake in my code UI
XML. I had a colon in the width value. IE was throwing an exception

Re: cache.html file is not cached with JBoss(Tomcat) and Internet Explorer 6-7

[pepgrifell]

Hi,

the problem is that *.css,*.js and images are cached but the only file
that is not cached is my cache.html file ... The file is about 3MB and
each time the users enter in the application, this file is downladed.
The only different thing from cache.html file and the others
(css,js,images...) is that cache.html file is gzipped before sending
it to the client.

I tried to add :




in META-INF/context.xml file (WAR) but it's not working either. (we
use JAAS. I tried with FormAuthenticator and SSLAuthenticator)


Any idea why cache.html file is not cached ?

Thanks !

Reading the error-message should help but independent
from that, the the answer is: It's an interface, baby.

It's a bit tricky but works.

You try to compile it for deployment or are we talking about
the hosted mode? if the latter, what's the error-message
showing up in the details-pane if you click on the main-entry

I come to the impression that you think that I'm some kind
of support-guy you have the right to use for free. That's
not the case, so please work on your way of asking questions:

 - Don't use exclamation and question marks excessively
 - Give as much information as possible to be able to
   reproduce or at least understand your problem
 - Don't forget: It's you, who want to be helped, so ask
   in a way motivating as much people as possible to
   help you.

I never needed to create a new implementation of java.util.List
but alway use ArrayList for the client side of the application.
Most likely java.util.List is not part of the client JRE that
is converted to Javascript leading to the error (but that's just
a guess, the error-message in the details-pane should clearify
that).

detecting if a widget is added to DOM or not

[Prashant]

Hi,

Suppose, I write my own custom widget using some features (say, third party
library features) which will work only if my widget is added to DOM, so,
those features need to be loaded only after the widget is added to DOM. Is
there any way to detect if widget is added to DOM? like, any method which
gets triggered when widget is added to DOM?

Thanks

Re: java.util.List

[Paul MERLIN]

Le lundi 23 novembre 2009 12:29:10, ben fenster a écrit :
> why cant i make a sub class for java.util.List
> every time i do i get compile errors

Documentation is clear :

  "Google Web Toolkit includes a library that emulates a subset of the Java 
runtime library. The list 
below shows the set of JRE packages, types and methods that GWT can 
translate automatically. 
   Note that in some cases, only a subset of methods is supported for a given 
type."

http://code.google.com/intl/fr/webtoolkit/doc/1.6/RefJreEmulation.html

java.util.List is in the emulated list but you'd better check if all methods 
are supported

I tried to write an empty implementation (no time to waste) of List, 
and GWTCompiler seems to be happy with it, 
so I'd suspect an error in your code (using something else that is not 
supported by gwt jre emulation).

By the way, you're asking insistingly without giving any valuable information 
for us to help you ... IMHO that's 
impolite.

Re: java.util.List

[Nathan Wells]

1) Is your class in a "client" package? by that, I mean does the
parent package have a *.gwt.xml file, and does it declare the
SmartQueue package as a source package?

If you haven't already, you might want to read this:

http://code.google.com/webtoolkit/doc/1.6/DevGuideCodingBasics.html

along with the rest of the Developer Guide. and probably the FAQ...
and the Reference Guide... and watch a few Google I/O videos.

Re: MenuBar in a Flextable cell

[Brian]

Sounds like a tricky problem. I haven't worked with menu bars so I'm
not sure this will work. What I'm thinking is that you could use a
placeholder menu bar in the table cell that doesn't have any menu
items. Then, when that is clicked on, display a PopupPanel with the
real menu bar and position it relative to the placeholder menu bar.
You may have to play with styling on the PopupPanel to remove any
decoration and/or margins to get the effect right. You'll also have to
capture which menu item (assuming there's more than one) was clicked
on the placeholder and simulate a click on the corresponding item in
the real menu bar.

Or maybe you can do away with the menu bar in the table cell
altogether and make your own drop-down menu using PopupPanels. It
depends on what you're looking for in terms of user interface feel.

I have seen a few crashes and that's why I'm build the firefox plugin
from trunk using the xulrunner provided by my distro.

$ cd plugins/xpcom/

getCurrencyFormat() - I want it to use $ as the currency symbol, not US$

[evan]

This is probably a dumb question but when I try to use
numberFormat.getCurrencyFormat() to format a double as currency, it
insists on using US$ as the currency symbol. If I do getCurrencyFormat
("GBP") it uses UK£, etc.

Is there a way to make it just show the basic currency symbol and not
the country code as well? My app doesn't deal with foreign (to the
user) currency, so if a person in the US sees $ she will not wonder if
it refers to US or AUS dollars.

Removing long classnames from RPC messages

[inventor]

Hi,

I would like to optimize RPC comminication of my GWT application. If I
look into the  RPC messages I am seeing many classnames from
serialized objects and I think the uncompressed message could be
nearly the half size if these classnames would be replaced by short
identifiers. Is there a way to achieve this?

Kind regards,

horizontal Alignment in a dialog box not working

[Neil Patel]

Hi All,

I have a simple dialog box that is constructed as below. For some
reason the single inner element (buttons panel) does not obey the
horizontal align setting. The element *does* align vertically. Any
suggestions are greatly appreciated.

==

public FooDialog() {
setText("Foo Title");
VerticalPanel outer = new VerticalPanel();
outer.setBorderWidth(3);
outer.setSize("400px", "200px");
outer.setHorizontalAlignment(HasAlignment.ALIGN_CENTER);
outer.setVerticalAlignment(HasAlignment.ALIGN_MIDDLE);

Button cancelButton = new Button("Cancel", new ClickHandler() {
  public void onClick(ClickEvent event) {
hide();
  }
});

HorizontalPanel buttons = new HorizontalPanel();
buttons.setBorderWidth(3);
buttons.add(cancelButton);

outer.add(buttons);

setWidget(outer);
}

Re: How to use Selenium to simulate the action of picking an item of SuggestionBox?

[Clint]

You need to instruct it to focus on the field, clear the field (some
browsers might keep the original text), type each key, and somehow you
need to type space as the last key to trigger the suggestions. So
basically just selenium.type(..) won't work.

GWT and FlowPlayer

[bmattar]

I am trying to replace JW Player with Flow Player in my web page.
My page used JW player via GWT2SWF widget, which works great. Flow
player however, needs to call a JS function to initialize properly.

Is there any way to get Flow Player to work with GWT2SWF?

The problem is that I want the player embedded in an HTMLPanel widget.
When I embed the Flow Player initialization JS code within the HTML
Panel widget text, it doesn't work at all. But when I embed the JS
init function in the static HTML page used by my GWT app, it works
fine!

(eclipse 3.5,GWT,macosx) a sample program seems to have bugs

[lolveley]

hello,

I tried to reproduce an example of program (from the magazine
"programmez", in french), using GWT, but there is an execution error,
which I cannot understand, but I know which lines are involved.

the program deals with a list of pictures; which are displayed.There
is a button "add" which allows to add a new picture, by entering its
name, its url.
the sample pictures are well displayed, but the error comes when I
want to add a new picture; the dialog box stays displayed a few
seconds and there is an error which makes the program stop.
the error is : "Invalid memory access of location 0010
eip=95d4e77b".

here is the code.
there are 3 classes : Miniature (which concern each picture),
Formulaire (which manages the addition of picture), and test!1, the
main classe.
nothing really complicated.

Re: OOPHM IE plugin doesn't work

[ageres]

Any updates?
I have the same problem using Vista + IE 8.0.6001.18828.

After first installation(GWT 2.Beta1) it worked for some time (at
least 1 day),
but after reboot it stopped working(Vista installed system updates and
requested for reboot).
I tried to repir/reinstall GWT plugin, but it still doesn't work.

I tried GWT2 Beta1, Beta2 and RC1, still no success.

error with the DEFAULT PROJECT in eclipse 3.5 with macosx

[loveley]

hi,

I have posted a former mail in which I spoke about an issue with a 
sample project.
now, I have the same issue with the DEFAULT project (the one created 
with the button "new web application project", in eclipse).
so the project isn't in cause, and the issue is elsewhere.

I use eclipse 3.5 JEE  cocoa 32 bits, for macosx, and the workspace is 
located in my HDD (before, it was located in my dropbox directory).
I downloaded GWT from the update site for eclipse 3.5, so the stuff is 
up-to-date.

the error is when I launch the default project, I have the first window 
asking me my name, I accept the default one, and then I have the "remote 
procedure call" window , all is good till I MOVE THE MOUSE, and then the 
program stops and in the console view I have the message : "Invalid 
memory access of location xxx".

can you help me?
it's urgent!

olivier.

Re: GWT as part of repository or not?

[Javier Molina]

I recommend you put it in your VCS. Having it in the repository does not 
impact anyone negatively and makes everybody's life easier. If you must, 
set up your project so that you can override the default version by 
changing a per-developer setting or an environment variable and you're 
good to go, but this should be for experimentation only. You should 
dictate an approved version and everyone should be using that; otherwise 
someone will commit code that uses newer features not available in 
previous versions and, generally, chaos will take over your project.

Re: GWT 2.0M1 java.lang.NoSuchFieldError WITH ECLIPSE PLUGIN

I had a similar problem.

Simple fix was to put the GWT classpath before Tomcat's

Re: Add class to SerializationPolicy whitelist...

[felix]

Hi,

i had the same troubles in my project once i moved from 1.5.2 to
2.0m2. I found the following solution:

1. create a class on the client code:

public class SerializableWhiteList implements IsSerializable {
@SuppressWarnings("unused")
private MyBean myBean;
@SuppressWarnings("unused")
private MySecondBean mySecondBean;
// Put here all Beans wich need this special treatment
}

2. Create a Method in your Service and ServiceAsync and ServiceImpl:

public interface MyService extends RemoteService {
public SerializableWhiteList serializableWhiteList
(SerializableWhiteList s);
}
public interface MyServiceAsync {
public void serializableWhiteList(SerializableWhiteList s,
AsyncCallback cb);
}
public class MyServiceImpl extends RemoteServiceServlet implements
MyService {
@Override
public SerializableWhiteList serializableWhiteList
(SerializableWhiteList s) {
throw new RuntimeException("This Method is only used to put 
Beans to
the SerializationPolicy, please do not call it");
}
}

Greetings

no border on a dialogBox (macosx,netbeans)

[lolveley]

hi,

I copied a program from a magazine with the purpose of learn GWT, and
all run fine except the dialog box has no border, as shown in this
picture : 
http://serv3.upndl.com/raw/6be0cb4a4b30f0e1eee2d4bede59/capture-decran-2009-11-22--14.05.59.png
.
I use netbeans with the plugin GWT4NB, I use macosx 10.6, I downloaded
GWT (the last one), and the application container is tomcat 6.0 .
can you tell me why the dialogbox has no border?

here is the code of the dialogBox :
*
public class Formulaire extends DialogBox{

public TextBox saisieUrl=new TextBox();
public TextBox saisieTitre=new TextBox();

public Formulaire(){

super();
setText("Ajouter une nouvelle image");
Grid grid=new Grid(3, 2);
grid.setWidget(0, 0, new Label("url"));
grid.setWidget(0, 1, saisieUrl);
grid.setWidget(1, 0, new Label("titre"));
grid.setWidget(1, 1, saisieTitre);
Button boutonAjouter=new Button("Ajouter");
grid.setWidget(2, 1, boutonAjouter);
boutonAjouter.addClickHandler(new ClickHandler() {

public void onClick(ClickEvent event) {
Formulaire.this.hide();
}
});
add(grid);
center();
}
}

*
and here is the code for the calling of the dialogBox :
*
public void onClick(ClickEvent event) {

if (event.getSource()==boutonAjouter){

Formulaire fenetreAjout = new Formulaire();
fenetreAjout.addCloseHandler(this);
fenetreAjout.show();


}
*


can you help me?

New to GWT - Suggestion Required

[Abdullah]

Hi All,

I am new to GWT infact new to AJAX itself, I was wandering for an ajax
framework and came across GWT, I went through the articles, docs etc
etc on GWT and found it to be interesting infact cool.

Now that I have decided to use GWT, I require some suggestion/advice
from you guys.

We have an ERP system, which I would like to Ajaxify, there are few
doubts which I would like to clear before I delve into this :

1) How do we manage sessions when using Ajax ? I have gone through
many articles on this, but I would like to know your thoughts on this.

2) Keeping in mind the 1 question, should I use xml-rpc or http ? I
gues xml-rpc would be better.

3) How to handle https ?

Hmm .. that's it for now .. this should get me started on GWT :)


Thanks,
Abdullah

Button Double Click

[hsk]

Hi Group.

I need an ordinary button on which I can click on and then something
happens.
Obviously I use the Widget 'Button' for that. But I also need to
double click on it so something else will happen.

To do this, I extend 'Button' and implement it with
'HasDoubleClickHandlers' and

public HandlerRegistration addDoubleClickHandler(DoubleClickHandler
handler) {
return addDomHandler(handler, DoubleClickEvent.getType());
}

This works (almost) very well by giving my button an addClickHandler
and an addDoubleClickHandler and implement what to do in each
overridden onClick and onDoubleClick for each respective added
handler.

My problem is, when clicking the Button it does what is has to do. But
when double clicking it does both what it has to do when clicked and
when double clicked.

Has anyone experienced something similar? how do I block the click
when double clicking?

WEB-INF/lib

[João Paulo Ferreira]

Hi guys

I'm new with GWT.
I created a gwt projetc using the google plugin for gwt 1.7.1.
After I added some jar's in war/WEB-INF/lib, I realized that this folder
wasn't in the classpath, like in a regular web project. Then I tried to add
the Web App Library, but this project wasn't recognized as a web project. I
also saw that in the project properties it didn't have facets options to be
configured.
I ended up adding the jar's in the classpath manually, one by one.
Is this correct?

Thanks in advance.

Persisting GWT Visualization API DataTable

[Matthew Planchant]

How should I go about persisting GWT Visualization API DataTable and
moving it between server and client?

I'd like to be able to build one on the client side, send it over the
wire and persist it in something like CouchDB. This should also be
able to work in the other direction. Pull a representation of a
DataTable from the DB send it to the client then rebuild the
DataTable.

Thanks for any advice/suggestions.

Matt.

UiBinder differences between styleName and addStyleNames

[djd]

Hi,
I have discovered that UiBinderGenerator has a (quite) strange
behavior while setting/adding Css styles.
Here is an example:



   
   


In LogoDisplay.css I obviously have the two styles (.basic
and .common). I also declared a custom CssResource (in LogoDisplay)
that binds with that Css file. The weird thing is styleName is
actually invoked using a setter (setStyleName) while addStyleNames are
invoked repeteadly using addStyleName, so it virtually same thing, but
the last style is not added (.common). I have also tried to use
addStyleNames="common" but it seems that I don't have the Css file
injected (and I would need to manually do that) and this does not work
either.

Can you help me? I'm sorry if the answer is extremely trivial, but I
was unable to find a solution for this problem (adding 2 or more
styles on a widget) - preferably I don't want to inject the Css (I
plan to have a lot of Css files, I don't want to inject all of them).

After compilation of StockWatcher example, GWT 2.0

[Zamy]

Hi all!
Initially, excuse me if you will find my questions a bit stupid, i'm
very noob :D
After the compilation of the example named StockWatcher, done
successfully, i saw all the correct file in the directory generated.

But, i have a dubt, and the tutorial isn't so clear at this point:
i want to see the compiled project, what i have to done?
I tryed to open the "hosted.html" page (both locally and remote), but
i only see that:
"This html file is for hosted mode support."

What i don't know?

thank for you help :)

Re: Button Double Click

You can override the method onClick of the button, to do nothing, so only
the method DoubleClick will work.

Re: Gilead + Guice + Gwt-Dispatch

[djd]

Yes, I worked on a sample code that achieved that a couple of month
ago... I will try to post some sample code as soon as possible (first
let me find it);
for now, allow me to give you some impressions :
* the idea is nice (modularization, clear code, simple classes, etc)
* BUT the implementation is painful:
- I remember that I had to extend the EngineRemoteServlet
(supplied with Gilead) - not very cool
- it boasts that "no web.xml anymore" - forget it, you have to map
quite a bit before making it work
- at that time there was no "hello, world" example of setting it
up
- A LOT OF BOILER PLATE CODE (Action, Result for every possible
interaction with the server). Way too much to actually make something
useful. After you write about 5 Action + 5 Result classes, you will
get what I mean
- You lose the feeling of coding with Java, because your remove
service interface has only one method (doExecuteAction-and-
getAResult).
- You cannot have more methods on the same interface - aka service
- (again, Java feeling is completely lost)
- Because of generics restriction (even through Rpc interface is
using generics, the type erasure is not considered when extending an
interface, so you cannot do something like "interface UserService
extends Service, Service<...>,
Service<...>

I will post some working code soon or you can PM me and I'll send you
the whole project

Re: java.util.List

[Jason Morris]

Hi ben,

If you are using a version of GWT < 2.0 this error appears because the standard 
GWT List interface 
doesn't have the subList method. You can either remove the @Override annotation 
from that method, or 
extend AbstractList instead of implementing List directly (generally considered 
a better option 
anyways).

You could also upgrade to GWT 2.0-rc, which has the subList method included in 
the interface definition.

Hope that helps.

Re: Can't debug in eclipse in development mode with GWT 2.0 RC1

[Jason Parekh]

Hi Youen,

Which version of Java are you using?  There was an issue where breakpoints
would not catch on JDK 1.6.0_14.

You can check the version being used under:
- Run > Run configurations
- Expand Web Application on the side bar
- Select one of its children, click on the JRE tab

Debugging the serialization process for GWT-RPC

[Eric]

Hello all,

I'm fairly new to GWT.  I have had one RPC service working for about 3
weeks.  Last week I implemented a second one.  No problems.  In the
last couple days I Implemented a third service not unlike the first 2,
but I did have to make some changes to my model classes.

Suddenly the first service returns 500 errors if the return value is
not null. The exception says to "See server logs for details" but I
can't find any clues in the server logs at all.  From everything I can
see on the "server" side everything completed normally.

I can put a breakpoint right before the return statement and
everything seems to be in order.  Is there any way looking into what
problem may have been encountered while trying to serialize the retrun
value?

I'm using Eclipse 3.5 with the 1.7.1 version of the plugin.

Sorry for the lack of specifics, but any tangible error message is
exactly what I'm looking for.

Thanks,
Eric

Re: java.util.List

thanks i removed the override and it worked can you please tell me why
 did act like that since the eclipse filled out the implementation
acording to the interface and if the method is not suppored  how did
it got into the imlementation in the first place

Making command pattern RPC look like traditional GWT RPC

[Jamie Gennis]

Hi all,

I posted this on the GWT Contributors group last week hoping to start a
discussion about the GWT internals that I'm using for the library I'm
working on (and whether they all need to be internals), but I haven't gotten
any responses about that so I'm reposting to the GWT developers group...

I've been writing a GWT library to implement the command pattern for GWT RPC
calls using the same interfaces that traditional GWT RPC uses.  Basically,
when an app calls a method of the FooAsync action service interface, an
action object is created from the method arguments, processed by some action
filters on the client, then passed to the server.  The server then pulls the
method arguments out of the action object and passes them as arguments to
the appropriate method of the Foo interface implementation class.  The
return value (or thrown Throwable) from that method then gets put into an
action result object on the server and sent back to the client, where it
gets processed by filters and eventually has the return value or throwable
pulled out and passed to the onSuccess or onFailure methods of the async
callback.

I have a working (albeit not extensively tested) implementation at
http://code.google.com/p/gwt-remote-action/, but the implementation relies
on some GWT internals, so it's rather brittle at the moment. I'd like to get
some feedback on how I can change my implementation to be more future-proof
(or correct if it isn't), and which (if any) of the GWT internals that I'm
using might be candidates for becoming a part of GWT's public interface.

To get a better idea of how this library is intended to be used, check out
the Usage Guide
(still a
work in progress).

The tricky part of the implementation is the action result.  The purpose of
an action result object is to encapsulate the result of executing an action
in such a way that action filters can manipulate it without having any
knowledge of what the action was.  It needs to contain an arbitrary return
value object or an arbitrary Throwable object (as well as an indication that
the Throwable was thrown rather than returned).  These objects are exposed
via the 
ActionResult
interface.
 Simply having a general action result class that contains a return value
field of type Object and an exception field of type Throwable is not
desirable because it would cause deserialization code for every class that
GWT knows about to be included in the compiled javascript.

The current implementation works by generating one action result class for
each RPC method.  Identical action result classes are generated by a GWT
Generator at gwtc-time (for the client) and via Java byte code generation at
run-time (for the server).  My original idea was that this method-specific
action result class could have a result field of the specific return type of
the method along with a field for each type in the method's throws list.
 This turned out not to be necessary (at least for the cases I've tested),
because when GWT calls the Generator for the
ActionExecutionService
(the
traditional GWT RPC that sends the action objects to the server) it doesn't
find any of the generated method-specific action result classes.  Because of
this I simplified the action result classes to just have one field of type
Throwable, and I verified that not all the Throwable classes get included in
the deserializable classes list in the *.rpc.log files.  I'm not sure that
this behavior doesn't depend on GWT.create being called in a specific order
or something else I'm not aware of, but that should be solvable by splitting
the throwables into multiple fields if needed.

Generating the action result classes after the ActionExecutionService gets
generated means that none of the deserializers for the return values and
throwables of the action methods get generated or rescued.  To get around
this I:

   1. Make the ActionExecutionService use the new deRPC implementation
   rather than the previous RPC implementation
   2. Use the RpcProxyCreator class to generate a dummy implementation of a
   deRPC proxy for the action service (this proxy doesn't get used)
   3. Add an @ArtificialRescue to the generated action service proxy to
   rescue the _TypeOverridesFactory class that the RpcProxyCreator generated.
This _TypeOverridesFactory class has all of the @ArtificalRescue's
   necessary to deserialize the fields of the generated action result class.

Step 1 is mostly acceptable to me, though it would be nice if my
implementation didn't depend upon an experimental feature that may not make
it into GWT 2.0.  Step 2 is somewhat wasteful since it takes gwtc time
generating a proxy c

lacking an interface with "setEnabled" method

[Michel Daviot]

Hi,

I think an interface defining the setEnabled method is lacking. This
would be implemented in FocusWidget, DateBox ...

dynamic Messages/ImageBundle possible?

[denis56]

Hi there,

I wonder if it is possible to use Internationalization and
ImageBundles in GWT in a more dynamic way. For instance, if there is a
client method

void createSportTitleAndImage(String sportId) {

}

is it somehow possible to have the  "sportId" argument  being
dynamically plugged into the relevant ImageBundle/Messages method to
return appropriate code without the if/else-jungle.

So instead of:

void createSportTitleAndImage(String sportId) {
 if (sport.equals("basketball"))
ImageBundle.getBasketballImage();
Messages.getBasketballText();
 else if (sport.equals("handball"))
ImageBundle.getHandballImage();
Messages.getHandballText();
 else ...
}

to have something like :

void createSportTitleAndImage(String sportId) {
ImageBundle.getSportImageById(sportId);
Messages.getSportTextById(sportId);
}

where getSportByName(sportId) would fetch resource for the key "base +
sportId" ?

That would really simplify things:)
Thanks

is the next version going to be 2.0?

[denis56]

His,

One more question. I am in the midst of one project development
running on gwt1.7. Is the next version going to be a jump to 2.0.
Would you recommend switching to 2.0 code base right away ?

thanks

Re: Can't debug in eclipse in development mode with GWT 2.0 RC1

[Jason Parekh]

Hi Youen,

Could you also make sure the launch configuration is using 1.6.0_15?  It
could be the case that your default JDK is _15, but when the launch config
was created, it was using _14.

Have breakpoints every work for you in this project?  How about more
generally in other projects in Eclipse?

It's also worth mentioning that trunk has an updated installer that installs
all data and registry entries to "User" (RC1 was installing to Program
Files\Google\...). You may want to try uninstalling the RC1 plugin and
trying out the latest. Note that trunk will contain the the .msi without the
.exe wrapper.

Re: Can't debug in eclipse in development mode with GWT 2.0 RC1

[Youen]

Ok in eclipse it's written that it is the default Mac OS X JDK, so it
should be the _15 version.

I make further tests and :
 - Breakpoints work on a project from scrath!
 - Breakpoints do not work with my 2 main (big) gwt project.

The main difference with my  2 project is that the main html file is a
Velocity template managed with spring MVC (so there is no main HTML
file in my war folder).

Re: Strang problem under 2.0 RC1+Google plugin for Eclipse.2rc1

[Chris Ramsdale]

Alex,

I would suggest leaving your existing application structure in tact and
simply updating the GWT SDK that you are building against. You can do this
via the Libraries section of the Java Build Path view.

Re: MenuBar in a Flextable cell

[Sudeep S]

Thank you for your suggestion.

i am trying a similar approach for this one.

instead of having a menu bar in the cell i have placed a simple link in the
cell and when it is clicked, i capture the cell and the absolute position of
link that is clicked.

With the absolute position of the link inhand i delete the link and place my
menubar at that position.

having little trouble with positioning though.

thanks

Keyboard navigation & shortcut

[Chrisnofneur]

Hi,

I am building a GWt app which has the following layout:

- FlowPanel
 * Menu Bar
  * Grid (2,x)

I want to add keyboard navigation to the Grid (UP, DOWN & DELETE)

I call the following code in the constructor of my Widget:

// EVENTS
Event.addNativePreviewHandler(new NativePreviewHandler() {

@Override
public void onPreviewNativeEvent(final NativePreviewEvent
event) {

// Key pressed
if (event.getTypeInt() == Event.ONKEYDOWN) {
// Update Grid status (up, down, delete)
}
}
});

When I press UP & DOWN keys, no problem I get the events.
The problem is that navigation in the MenuBar also fires key events
which are catched by this code.
So when I select the MenuBar I have a double navigation: in my MenuBar
and in my Grid

The questions are :
- How can I prevent my code to catch events which target elements like
MenuBar & TextField ?
- Is there another way to deal with my problem ?

Thanks

Chris

Re: External libs in GWT app

[Jason Parekh]

Hi Jacek,

1)  war/WEB-INF/lib is the correct place.  Could you describe when your JARs
in there get deleted?  Is it on any build (including Eclipse's incremental
build) or only when you clean and do a full build?
2)  There isn't a UI for this, so most people do a GWT compile and JAR up
the war directory.

(macosx) how to launch netbeans with the jvm option -d32 ?

[lolveley]

hello,

I use macosx snow leopard with netbeans (the last one) and GWT with
the plugin GWT4NB.
I can't use the debugging from the java code, I have this error:

**
You must use a 32-bit Java runtime to run GWT Hosted Mode.
  Leopard: Use the Java 1.5 runtime.
  Snow Leopard: Use the Java 1.6 runtime and add the -d32 flag.
/Users/lolveley/NetBeansProjects/StockWatcher/nbproject/build-gwt.xml:
117: The following error occurred while executing this line:
/Users/lolveley/NetBeansProjects/StockWatcher/nbproject/build-gwt.xml:

/Users/lolveley/NetBeansProjects/StockWatcher/nbproject/build-gwt.xml:
363: Java returned: 1
BUILD FAILED (total time: 5 seconds)
***

do you know how I can launch netbeans with the option -d32?
I had a look at the netbeans file, and I found in netbeans/content/
resources/netbeans/etc/netbeans.conf the lines :

***
# ${HOME} will be replaced by JVM user.home system property
netbeans_default_userdir="${HOME}/.netbeans/6.7"

# Options used by NetBeans launcher by default, can be overridden by
explicit
# command line switches:
netbeans_default_options="-d32 -J-client -J-Xss2m -J-Xms32m -J-
XX:PermSize=32m -J-XX:MaxPermSize=200m -J-Xverify:none -J-
Dapple.laf.useScreenMenuBar=true -J-Dsun.java2d.noddraw=true"
# Note that a default -Xmx is selected for you automatically.
# You can find this value in var/log/messages.log file in your
userdir.
# The automatically selected value can be overridden by specifying -J-
Xmx here
# or on the command line.

# If you specify the heap size (-Xmx) explicitely, you may also want
to enable
# Concurrent Mark & Sweep garbage collector. In such case add the
following
# options to the netbeans_default_options:
# -J-XX:+UseConcMarkSweepGC -J-XX:+CMSClassUnloadingEnabled -J-XX:
+CMSPermGenSweepingEnabled
# (see http://wiki.netbeans.org/wiki/view/FaqGCPauses)

# Default location of JDK, can be overridden by using --jdkhome :
netbeans_jdkhome="/Library/Java/Home"

# Additional module clusters, using ${path.separator} (';' on Windows
or ':' on Unix):
#netbeans_extraclusters="/absolute/path/to/cluster1:/absolute/path/to/
cluster2"

# If you have some problems with detect of proxy settings, you may
want to enable
# detect the proxy settings provided by JDK5 or higher.
# In such case add -J-Djava.net.useSystemProxies=true to the
netbeans_default_options.


I made 2 changes : I added the -d32 option and I specified the java
directory.
but there is still this error...

help me please!

How to set the format for a DateBox?

DateBox.Format does not allow for the setting of a custom format.

Re: Debugging the serialization process for GWT-RPC

[Eric]

OK.  I made some progress.  I added a couple properties to my model of
type "List".  Removing those allows the rest of the
class to be serialized.  I'm still not sure why those properties won't
work.  My guess is that since they are populated through JPA, they
were some kind of funky list.

My main question remains, however.  Where could I look to see "Can't
serialize this list" instead of "An error occured"?

Thanks,
Eric

system will not work with AppEngine, or if this is a bug that can be
filed/tracked.

Re: GWT 2.0 RC1 deRPC fails on App Engine?

[Chris Ramsdale]

You can track progress on this issue here:
http://code.google.com/p/google-web-toolkit/issues/detail?id=4185

App Engine deRPC support will be available in a post 2.0 release.

GWT AsyncCallback failing

[NeeravA]

I call a GWT server method which executes perfectly and returns the
desired object. But the on return the AsyncCallback enters onFailure
method. There is no exception on the server end. On the client side I
get the following Throwable exception.

com.google.gwt.user.client.rpc.StatusCodeException: The call failed on
the server; see server log for details

problem. Please suggest few things that can cause this error.

Yes it does:

   myDateBox.setFormat(new DateBox.DefaultFormat
(DateTimeFormat.getFormat(",  dd, ")));

or you could use your own custom Datebox.Format implementation:

   myDateBox.setFormat(new MyCustomDateBoxFormat());

You'd have to test whether MenuBar.getElement().isOrHasChild(Element.as
(event.getNativeEvent().getEventTarget()))

Why not use event bubbling (aka event delegation) instead of event
capture? i.e. either:
 - put the Grid into a FocusPanel and addKeyDownHandler(...)
 - extend Grid and addDomHandler(..., KeyDownEvent.getType())
(eventually implementing HasKeyDownHandlers if you don't want to
handle the KeyDown within the Grid but in the widget that uses the
Grid)

The user would "just" have to click the Grid (or FocusPanel) to have
her keyboard interact with the grid (i.e. as soon as she clicks the
MenuBar or anywhere outside the grid, the handler is no longer called)

Re: GWT AsyncCallback failing

[Yozons Support on Gmail]

Be sure there are no null pointer errors and that all classes you serialize
also have a no-arg constructor (that one gets me from time to time) even if
you don't use it yourself (I have a lot of private constructors just for
serialization).
