Is it a small bug in samle StockWatcher?

2009-03-11 Thread 秦锋


I'm newbie to GWT and read the tutorial of StockWatcher now, here is
my question:
In 
http://code.google.com/intl/zh-CN/webtoolkit/tutorials/1.5/codeclient.html#addStock,
"3. Add a button to remove stocks from the stock list", following is
the code:

int removedIndex = stocks.indexOf(symbol);

My question:
where is the "symbol" from?
It's in a listener's method, but defined in "addStock" function?

Re: embedded flash not displaying is IE7 on secured url but works fine when viewed with unsecured url

2009-03-11 Thread Tony Strauss

This just is a wild shot in the dark (I have very limited experience
with Flash) but could it be a problem with the cache control headers
in the response returned by the server?  I've had a number of issues
with IE (even IE7) + HTTPS that have resulted from this.

See:
http://google-web-toolkit.googlecode.com/svn/javadoc/1.5/com/google/gwt/user/client/ui/ImageBundle.html
for a discussion of this issue for the GWT ImageBundle.

See this:
http://drupal.org/node/163298
for a discussion of the issue in a different context.

Also this for downloading MSOffice files:
http://support.microsoft.com/kb/316431

Basically, IE cannot download files successfully over HTTPS if caching
is completely suppressed.  Any of:
Pragma: No-cache
Cache-Control: no-cache
in the response header will cause IE problems over HTTPS.

Changes to Overlay Types

2009-03-11 Thread Rajesh Akkineni


I have a problem with accessing the changes done in a native method of
Overlay Type.

class A extends JavaScriptObject{

public native void toB(String b)/*-{
  this.b=b;
}-*/;
public native String getB()/*-{
 return this.b;
}-*/;

}


This this example 'toB' method and 'getB' are called from two
different places on same A object. But the values set in toB are not
available in getB. How is it possible? Other properties which are
present A before these methods are called are still available in both
places. But any new properties are not available.

Only explanation is that when javascript returns an Overlay type to
Java it wraps in a new object that is derived form old object. Am I
Correct? Is there any way to overcome this limitation. (I have not
tested in web mode)

Thanks for any help

See http://code.google.com/p/google-web-toolkit/issues/detail?id=3278

The problem is the use of AlphaImageLoader for PNG transparency in IE,
which resolves paths relative to the page, not the CSS. This is solved
in 1.6 by getting rid of AlphaImageLoader in the 3 default themes
(using binary transparency in IE6, IE7 supports PNG transparency
without AlphaImageLoader)

Re: [ANN] Gilead 1.2.2

2009-03-11 Thread Itamar Ravid

Hi Bruno - first off, thanks for all of your hard work. Your project is a
real life-saver, and we're using it extensively in our project.

I'd like to report a bug. I have not tested yet with gilead 1.2.2, but I'd
like to report it anyway.

Assume two classes:

public class Status {
Long id;
String name;

public Long getId() { ... }
public Long setId(Long id) { ... }
public String getName() { ... }
public Long setName(String name) { ... }
}

public class Ticket {
Status status;

public Status getStatus() { ... }
public Status setStatus(Status status) { ... }

public String getStatusName() { return getStatus().getName(); }
public String setStatusName(String name) { getStatus().setName(name); }
}

I've omitted the getters and setters for brevity, as I assume their contents
is well known. The problem occurs when serializing a Ticket instance. I
suspect that the problem lies in beanlib, though I wanted to consult you
first.

While serializing a Ticket, I receive a NullPointerException, while beanlib
tries to access the delegate method getStatusName in Ticket. I've come to
suspect, through debugging, that this happens since beanlib tries to copy
the statusName property (which does not exist) -before- copying the status
property. It'd be great if you could confirm my assumptions. For now, we've
prefixed all delegate methods with an underscore, to prevent beanlib from
recognizing them as property getters/setters.

Any thoughts?

Re: Guide to GWT theme CSS

2009-03-11 Thread Ian Bambury

The JavaDocs tell you what the style names are.
Some browsers will show you the HTML including style classes and what values
they are set to and where they came from.

GWT.log(widget.toString()); or Window.aler(idget.toString()); will also
display the HTML and the style classes.

Re: WMS Maps

2009-03-11 Thread loott

Hello,

I've being using WMS with GWT using openlayers. It has an integration
with gwt: http://sourceforge.net/projects/gwt-openlayers.
But I recommend you to look the openlayers simplest examples and use
them from GWT with JSNI. It  will be quicker for you.

If you prefer to use the plugin, there's a tutorial to use GWT +
openlayers + geoserver here:
http://geoserver.org/display/GEOSDOC/Google+Web+Toolkit+(GWT),+OpenLayers+and+GeoServer.

It's a bit old and I think it won't compile with newer versions of
GWT, so if you want to follow the tutorial you'll got to get the
latest version from the plugin from CVS and build it yourself.

Bye

Guide to GWT theme CSS

Hi,

I've been working on a custom theme, starting with a copy of one of
the GWT defaults. Is there a guide to the CSS anywhere, or are you
expected to just muddle around with it when you want to change colors,
etc. For instance, most dialog borders appear to be comprised of
images, but I can't figure out the top border. I've been weeding
through the CSS and just haven't found the correct style specification
or something, but it's becoming time consuming. Plus, it appears you
can't view source on the file as the elements are JS-generated, so I
can't see what style is applied to the elements anyway, hence the CSS
hunting.

a.b.app1.client
a.b.app2
a.b.app2.client

OR
a.b.app.client (all files are under 'client' directory)
3. How did you code the 'transfer' from login to main app?

Re: Using java.io.File within a GWT unit test

2009-03-11 Thread alex


You simply can't do that, hosted mode or not.

java.io.*, java.net.*, java.util.concurrent.*, etc are packages that
cannot be used within GWT's client side code.

However, if you want to read a file (AFAIK the limitation is: not from
disk, but from a given URL) you can use the RequestBuilder class, like
this:

[ANN] Gilead 1.2.2

2009-03-11 Thread noon


Gilead library permits you to send Persistent entities (and especially
the partially loaded ones) to the GWT  client side without pain.

This release is a maintenance one, fixing half a dozen bugs, and
providing many improvements (see release notes for details).

A particular work was made on improving clone performances.

Also note that hibernate-jpa-util have been now merged with hibernate-
util JAR, and some integration classes for JBoss and Spring are now
provided.

Hope this helps !

first child of VerticalPanel doesn't get mouse-events

2009-03-11 Thread Michael


Hi there,

I'm new to this GWT stuff, and am trying to create a cascading
calendar along the lines of a menu with child menus.

So far I've knocked the following together, but the first child of the
VerticalPanel does not get any of mouse-events. If you uncomment the
line below so that there is a "dummy" first-child Widget, the mouse-
listener fires.

---
public class CalendarWidget extends PopupPanel {

private DateTimeFormat yearValue = DateTimeFormat.getFormat("");
private String[] months = { "Jan", "Feb", "Mar", "Apr", "May", "Jun",
"Jul", "Aug", "Sep", "Oct", "Nov", "Dec" };

private Panel debugPanel;

public CalendarWidget(Date startDate, Date endDate) {
super(true, false);
int startYear = Integer.parseInt(yearValue.format(startDate));
int endYear = Integer.parseInt(yearValue.format(endDate));

int size = (endYear - startYear) + 1;
VerticalPanel yearPanel = new VerticalPanel();
add(yearPanel);
//  yearPanel.add(new Label("1st child"));
MouseListener yearListener = new CalendarMouseListener();

for (int idx = 0; idx < size; idx++) {
Label yearLabel = new Label(Integer.toString(startYear 
+ idx));
yearLabel.addMouseListener(yearListener);

Image image = new 
Image("/velocity/images/email_lbl.gif");
image.addMouseListener(yearListener);

HorizontalPanel labelPanel = new HorizontalPanel();
labelPanel.add(yearLabel);
labelPanel.add(image);
yearPanel.add(labelPanel);

}
debugPanel = new VerticalPanel();
RootPanel.get().add(debugPanel);
}

class CalendarMouseListener extends MouseListenerAdapter {

@Override
public void onMouseEnter(Widget sender) {
debugPanel.add(new InlineLabel("mouse-enter"));
}

@Override
public void onMouseLeave(Widget sender) {
debugPanel.add(new InlineLabel("mouse-leave"));
}

@Override
public void onMouseUp(Widget sender, int x, int y) {
debugPanel.add(new InlineLabel("mouse-up:" + x +"," + 
y));
}
}
}


An explanation as to what's happening would be gratefully received, as
would an example of the correct pattern to follow to do this as
elegantly as possible.

Best wishes,

Michael

gwt version: 1.5.3 for mac.

public interface GsImageBundle extends ImageBundle {

public static final GsImageBundle INSTANCE = (GsImageBundle)
GWT.create(GsImageBundle.class);

AbstractImagePrototype logo98x40();

}

in onModuleLoad method

//get Image Bundle
GsImageBundle gsImageBundle = GsImageBundle.INSTANCE
.

panel.add(gsImageBundle.logo98x40().createImage());


.

gives me an error when I run the app..

How to debug IE6 crash

2009-03-11 Thread Austen


Hi,

I have a problem with IE6 crashing when using my app.
The app works fine in IE7/FF3/Chrome etc.

I'm attempting to use MS script debugger with no luck. The error isn't
caught by script debugger (or maybe it is, but it crashes before I can
view it) and when I try and step line by line IE6 still crashes before
I get to see anything interesting.

The problem is, how do I find the problem?!

Anyone got an idea on how to proceed?

Thanks in advance

Button paddings in IE fix

2009-03-11 Thread georgopoulos.georg...@gmail.com


Hi,

Based on http://particletree.com/features/rediscovering-the-button-element/

adding in .gwt-Button CSS rules the line:

.gwt-Button {
  /* ie fix */
  overflow: visible;
}

will fix the extra paddings added by IE depending on the button's text
length, see:

Re: how can i get a Dynamic Image

2009-03-11 Thread Darkflame

What your making is called a "Captcha"
Theres many about, and they are being broken all the time, so (for
once) it probably is a good idea to make your own one if possible.

What you want to do though is make it as hard as possible for software
to recognise what has to be entered into the field.
Normaly this is done by distorting an image file of the text to be
entered.
However, this probably isnt the best thing to attempt ver GWT, and
maybe a more elgant solution would be some kinda of other "human
test".

A good old bit of mathmatics purhapes?
Ask the user a silly but easy question like;

  "If there is 6 ducks and 7 pigs, how many animals in total?"

Only with random numbers.
You can make it more complex by adding dumy data too, by saying;
"If there is 6 ducks ,  7 pigs and 3 bikes, how many animals are
there?"

Unless a spammer specificly writes software to target your site, that
sort of techique should get you safe. (I think).

Shouldn't everyone stop using GWT-Ext so we can get critical mass in a supported library?

2009-03-11 Thread tv


FWIW:

I'm looking at starting a GWT project using a widget library add-in.
Only after reading for some time did I realize there was some tension
between the team that created the Ext JS library and the team that
created the GWT-Ext library (that relies on Ext-JS).  So now there are
two alternatives it seems to me for those that want to carry on using
a widget library like this:

smartGWT (LGPL or commercial)

-or-

Ext-GWT  (GPL or commercial)

I don't have a bias in either one, except that it would be great if
there was a clear leader or at least if people stopped developing
expertise in GWT-Ext since it is essentially a project that is no
longer of interest to its creators.  I learn so much from other
people's questions on these topics - I would rather see everyone start
using a library that will continue to evolve, so we can start helping
one another.

Is there a better alternative out there?

Thanks.

Re: Migrating to GWT 1.6 NoClassDefFoundError: org/apache/jasper/runtime/JspSourceDependent

2009-03-11 Thread Masto


Hi Vitali, thanks for you answer,

If you look at my first post, you see that my classpath contains the
path to the build of my other project.

/Users/thomas/Dev/Inv_WEB_v2/Inv_WEB_v2/Proj_3/build
/Users/thomas/Dev/Inv_WEB_v2/Inv_WEB_v2/Proj_2/build
/Users/thomas/Dev/Inv_WEB_v2/Inv_WEB_v2/Proj_1/build

But using that, JETTY cannot comile my JSPs. It cannot find some
classes I use in my JSPs unless i put the jars in the WEB-INF/lib

"Oh and gwt-dev-anything.jar should not go into your WEB-INF/lib."

I know that. But again, if i don't put this jar inside WEB-INF/lib,
The Hosted mode refuses again to compile my JSPs but this time because
it cannot find the class org/apache/jasper/runtime/JspSourceDependent
which is inside the gwt-dev-*.jar.

My JSPs are not integrated with GWT. I have one for the sign-up screen
and one for the sign-in screen. That's it. They use some classes from
my Proj_1, Proj_2 and Proj_3 (no GWT projects) and some Javascript
(prototype). That's it. They are plain old JSPs. No fancy stuff in
there. Currently, they are under my public path in my GWT project.

To reproduce the issue (or try to), create a JSP and see if it works
when you don't have the gwt-dev-*.jar inside your WEB-INF/lib. Your
JSP have to use a classe (just do import org.myCompany.myClass) from
another project to reflect my case



if i don't put all the jar files,

Same here. I'm using ubuntu 8.10 64 bit. If you run a 32 bit JVM for

I'm developing on gwt 1.5  with eclipse running on  java 1.6 64bits, with
the gwt projects configured to run on java 1.5 32bits. I can debug in hosted
mode perfectly. It's deployed on a tomcat 6 running java 1.6 64 without

In my understanding of GWT 1.6 OOPHM, you should be able to debug with
all-64bits and your normal firefox.

Yes, I think so.

You just need to make sure that when there is a new version of the GWT code
that the host HTML page will be expired, so clients can see what the new
name of the nocache file is.  In other words, you are shifting the need for
nocache from the $module.nocache.js to the host HTML page that is importing
it.

Re: rpc call with own datatype not working

2009-03-11 Thread Isaac Truett


You really have a module configuration issue more than a serialization
issue. Your Workspace class isn't part of a module.

You can read more about modules here:

http://code.google.com/docreader/#p=google-web-toolkit-doc-1-5&s=google-web-toolkit-doc-1-5&t=DevGuideModules

You can also search for the error message you received ("No source
code...") and you'll find that this has been discussed here a number
of times already.

You basically have to do one of two things:

1. Move the Workspace class into a package that is part of an existing
module (e.g., com.foo.client).
2. Create a module that includes the Workspace class.

I'd go with #1, since the Workspace class as you posted it isn't very
well packaged to begin with.

Hope that helps.

- Isaac

Re: rpc call with own datatype not working

2009-03-11 Thread George


Hi,
i'm still having this serialization issue. It would be nice if someone
could help me out, as I still don't get whats going wrong here.
What is causing the error? Is it the fact that the serialized class is
not in the same package as the service? Or am i missing one of the
special Javadoc annotations (@gwt.typeArgs), of which i thought that i
don't need them here.

Please Help me out.

Would it be reasonable to set a far future expiry date on a gwt

Re: Need help with debugging

2009-03-11 Thread Sean


Sounds like your Eclipse Debug profile is messed up. When you hover
over Debug, make sure it says "Debug ". IF that's
correct, don't click the button, but click the arrow next to it and
hit "Open Debug Dialog" and make sure that all the parameters in there
are correct, Project Name, Main Class, Arguments...etc.,

I would also double check your project creation, the fact that you
can't import projects using "Existing Projects into Workspace" is
worrisome. Here's an example of my commandline creation that lets me
import the projects into workspace option:

C:\Workspace_spl\Test>C:\gwt\projectCreator -eclipse Test
Created directory C:\Workspace_spl\Test\src
Created directory C:\Workspace_spl\Test\test
Created file C:\Workspace_spl\Test\.project
Created file C:\Workspace_spl\Test\.classpath

C:\Workspace_spl\Test>C:\gwt\applicationCreator -eclipse Test
com.sean.client.TestEntry

CustomWitingOperation.java

public class CustomWaitingOperation {

public interface ResultCallback {
void onResult(boolean result,Throwable caught);
  }

public CustomWaitingOperation(/*Parameters Here*/) {

Re: GWT OpenSocial Binding - usage problem

2009-03-11 Thread Eric Ayers

If you are talking about the gwt-opensocial hosted at

http://gwt-google-apis.googlecode.com/svn/changes/haeberling/opensocial-initial

Then you also need to inherit com.google.gwt.opensocial.OpenSocial in your
GWT module.

Keep in mind that this is a pre-release version of the code.

Re: DATEBOX & HOURS RESETTED

2009-03-11 Thread Arthur Kalmenson


I think the easiest solution is to put the time in a TextBox beside
it. If you want something fancier, check out the Spinner in the
incubator: 
http://code.google.com/docreader/#p=google-web-toolkit-incubator&s=google-web-toolkit-incubator&t=Spinner.
One of the examples is picking a date and time.

Re: how to change url address

2009-03-11 Thread denis56


his again,

is it also possible to place generated javascript and prc files in
subfolders?
so instead of having everything lying in the same directory, it would
make sense to have

html pages
-- css subfolder
-- js subfolder
-- images subfolder

thanks

Re: GWT RPC Security Concern

2009-03-11 Thread Adligo


This is true until you start passing rpc objects that describe what
they are going to do on the server.

For instance a rpc service like;
getAnimal(String name)

If the vet should be the only person able to get the 'Bob Cat' and
'Cobra' but the nurse can get the 'Dog' and 'Cat'...

For methods like this you need to add isUserInRole checks inside your
rpc servlet (in addition to you http filter).  You can either check in
the rpc method or
use something like this class, to put all of this type of security
code in a common place;

http://cvs.adligo.org/viewvc/adi_gwt_rpc_servlet/src/org/adligo/i/adi/server/rpc/AdiControllerServlet.java?view=markup

Cheers,
Scott

Re: Tree Performance

2009-03-11 Thread gregor


yeah, I thought of that Vitali, but I thought what FastTree did was to
pre-load the entire TreeItem dataset (i.e. fetch all data in one RPC
operation) but then only actually draw visible tree layers, thus
cutting down repeated RPC fetches on lazy tree node open but still
only draw what is required on open clicks.

Which is no good for this situation because GWTFan has a flat tree
structure, i.e. all 1000 items in same branch?

Re: GWT 1.6 works on 64 bits?

2009-03-11 Thread Kristal


Hi,
I experienced troubles running my gwt app on a 64 architecture
(ubuntu).
Apparently the problem comes from the hosted mode that relies on a 32
bits version of mozilla.
This problem could be solved by installing a 32 environment with
chroot, and I read that gwt coders where planing on changing their
hosted mode in the 1.6 release, and that's why nobody worked on a 64
bits version of the hosted browser.

I just downloaded the 1.6 version but didn't try it yet.
In case I wasn't clear:
-the 64 bits problem occurs in hosted mode, and the problem is linked
to the 32 bit mozilla plugin that is used in version 1.x -> 1.5.3
included.
-gwt 1.6 should come with another plugin (can't remember the details
though) which does not require a 32 bit architecture anymore
-the 64 bit uncompliancy should therefore be solved with gwt1.6, but
it is yet to be confirmed

regards,
Christopher

"Better" project layout

Did someone manage to create a more "maven" like project layout with

I was hoping to get rid of the maven plugin with the "new flexibility"
we won with 1.6, but I did not succeed at first.

Well, you have to create a generator that instrospect you classes in compile
time. The simplest variation is to inspect your beans, and beanadapters
generators are available on the net. This document was very usefull to me:

Full reflection is provided by more complex

Generate code at compile-time.

Googling for "gwt reflection" gives a bunch of relevant results:
http://gwtreflection.sourceforge.net/
http://code.google.com/p/gwt-ent/
http://code.google.com/p/gwt-greflect/

(by the way, "GWT.create(String.class)" is almost equivalent to "new
String()", it doesn't give you a Class object; "String.class" would,
but with very limited features in web mode)

Re: Tree Performance

2009-03-11 Thread gregor

I have never tried using StackPanel like that, but I did look at it's
code once to enhance it and I think it is at least as "complicated" as
Tree (in the sense it has many HTML "boxes") so I would guess it would
probably be if anything worse than Tree in your situation.

The classic way to deal with large trees is to lazy load them by
layer, but obviously that is not an option for you as you only have
one layer.

I think you'll have to figure out a creative way to design a widget to
deal with this edge case (1000 items). It's a bit difficult to suggest
anything because we don't know either the contents of the tree nodes
(what these 100 items are) or how they are used (presume user selects
them?)

One idea that that immediately occurred to me was to use
DisclosurePanels. This has a right pointing triangle when closed, and
when clicked reveals the contents, rather like clicking the + on a
Tree. I am assuming also that the problem is purely rendering and that
there is no time problem fetching the 1000 items over RPC. You could
make a Composite widget like so:

Choose a container, could be FlowPanel, VerticalPanel etc
Keep a list of the items as a member of this class, and a cursor to
keep an index against the list
Set a maximum number to be rendered at any one time, say a few more
than your happy days case of <=10
Iterate through the list making DisclosurePanels and adding them to
the container as you go
If the list size > your chosen max, add a button bar to the bottom
giving forward/back options

Etc, I'm sure you get the idea. I think rendering 10 - 15
DiclosurePanels at a time will probably be quick enough.

Re: Migrating to GWT 1.6 NoClassDefFoundError: org/apache/jasper/runtime/JspSourceDependent

2009-03-11 Thread Vitali Lovich

Oh and gwt-dev-anything.jar should not go into your WEB-INF/lib.  That set
of jars is strictly for HostedMode stuff & again - just add it to your
classpath.  They are not for deployment.

As for where to put the JSPs, that's a good question.  There's little
documentation as of yet (since 1.6 still hasn't been released).  Also, I've
never tried integrating JSPs with GWT (mainly because it seems antithetical
to the whole premise of GWT.

The JS libs, if I'm not mistaken, could be put into the war/module directory
that gets created or just in the war directory itself - it's up to depending
on how you specify the path (war/module is probably easier).

You only need to put your server-side stuff into WEB-INF/lib and only when
you are deploying to your server (should be part of your ant script to build
your war).  Otherwise, just adding to the build path in Eclipse works great
(you don't even need jars - just add projects to your classpath).

Re: Tree Performance

2009-03-11 Thread Vitali Lovich

Probably not since it's still the same problem in essence - that you are
manipulating the DOM a lot.

Here are some things to try:

Build the widget first using javascript & then add it as one thing (although
if you still pass it off to TreePanel, it's probably not going to help since
TreePanel will still build the model again).

Use lazy panels (I think it's in 1.6 but it's also in the incubator AFAIK) +
stack panel.  That may work.

Another trick might be to use a timer & incrementally add 1 results every 50
milliseconds or so.  That should keep the UI responsive, although I'm not
sure how IE will perform with a large tree once its there anyways.

In fact, on the GWT incubator sight, it does seem like they implemented the
lazy panel + stack panel idea anyways
http://code.google.com/p/google-web-toolkit-incubator/wiki/FastTree - that
sounds exactly what you're looking for.

Re: Synchornous GWT, how can i do that

2009-03-11 Thread Vitali Lovich

It's not really a matter of this being GWTs way.  I believe this is the only
thing browsers support since they do not have multiple threads, at least so
that the UI doesn't lock up.  And by UI lockup, I don't mean the page is
unresponsive - I mean the whole browser used to freeze if a page was in a
Javascript loop (actually still does on Firefox).

New browsers have multi-threading, but I believe that multi-threaded
Javascript constructs are still a ways away.

On the HTML page that includes your GWT script try doing something

You can then be sure it is referencing the correct JS.

Re: Synchornous GWT, how can i do that

2009-03-11 Thread eggsy


I agree with all the previous posts that Asynchronous is the best way
and that is why GWT only implements this.

When I started with GWT I was asking a similar question and was
correctly advised to think in terms of Async not Sync the more
development you do with GWT you'll realise this.

However at the time we did come up with a basic transactional pattern
that performs the methods synchronously:

http://www.axonbirch.com/blog/2007/10/26/notification-end-of-rpc-call/

But as before I would advise that you simply look at this and try
*not* to implement your methods synchronously if possible.

Re: Synchornous GWT, how can i do that

2009-03-11 Thread ping2ravi


I totally agree with you guys that Asynchronous is good, but i would
love to see mix up of synchrnous and asynchronous in GWT(my personal
view), where i can make an asynchronous call to one function which
internally can make synchronous calls and it will solve the problem of
UI hanging.(In case GWT peope can read it , please implement such
things), i am sure programmers will enjoy some synchronous calls too
such as avoiding inner classes or writing new classes for callbacks
for each call(again personal view). But yes User satisfaction has more
priority.
And guys i am really thankfull to all of you for giving suggestions

i guess i will implement some kind of chains as Matias Costa suggested
and once all chain object get result back will call our UpdateUi
function as suggested by Ian.

"How much extra code is too much?" - single line of (unnecessary)
extra code is way too much.

Re: IE8 DialogBox in GWT 1.5.2 Renders Wrong

2009-03-11 Thread Vitali Lovich

Sounds like a bug - you should file a bug (under the issues tab of the
googlecode page).  GWT's goal is that you shouldn't care about the browser
*unless you're doing some JSNI stuff).

If you figure out a workaround in code, you can hide it behind a deferred
interface & the GWT compiler will take care of everything for you.  Also, I
would recommend testing against Opera and/or Safari to provide a little more
perspective when you file the bug.

Re: Help regarding Date in GWT

2009-03-11 Thread jagadesh


I think u will get the value in dateformat only.
if u use DateField.getValue() it will return the value as Date
object.so no need of converting into Date Object. u can use directly
