Hi,
Don't much about recent GWT version.
But I the beginning of GWT I18N a simple solution was to use the I18N

Simply provide in a key locale( ex: locale=en ) with the correct value in

Re: Possible to access GWT-RPC serializer?

2010-07-16 Thread Olivier Monaco

Hi Sekhar,

You have some framework like piriti (http://code.google.com/p/piriti/)
for JSON serialization of data. It can be a good start. However, it
does not use overlays: it copy JSON values to POJO fields.

Maybe you can be interested in my code: 
http://code.google.com/p/tyco/source/browse/?repo=tikray
The idea is to define interfaces for data. A generator automatically
create implementation for GWT with zero-overhead (no field copy, just
wrappers arround JSON value that will be removed by the GWT
optimizer). This part starts to work with (many) limitations. The
second part is to create some Java proxy to use the same mechanisms on
server. I'm owrking on. Maybe this code can help you.

 Thanks guys, yes looks like JSON is the way to go. POJO-JSON should
 be easy (using the JSON API), but the other way is a bit tricky. I
 don't think overlays help because the JavaScript side never sees the
 objects (just the string) and the JSON-POJO process shouldn't depend
 on the specific class. As I understand overlays (http://goo.gl/fNzG),
 you need to (1) have the object in JS and (2) know the attributes.

 I'm experimenting with rolling my own, will post back results.

 You can gain access to the GWT-RPC serialization code (provided your

 the appropriate serialization/deserialization code), but it won't be
 of any help in your case, as GWT-RPC serialization is asymmetric (for

Re: Urgent!!!!!!!!!!!!!!!!!!!!!!!!!!! GWT 2 Memory leak

When the composite was removed the list stay in memory, so to solve

method called by GWT framework.

consumption increases on the machine that is hosting your application,
the problem has nothing to do with GWT at all, since all the
javascript code is generated at compile time and executed on the
client side (in the browser).
Your description indicates that your server side code is leaking
memory. The best way to fix this problem is to thoroughly analyse your
application's runtime behaviour by profiling the application with
tools like JProfiler, Yourkit or the NetBeans Profiler.

Does it exist a place to suggest improvement ?

2010-07-06 Thread Olivier

Hi there.

I am wondering if there is a place to suggest needs of improvement for
GWT.
I am working on a project and we tried to put in place some
architecture that needs some improvement.
For the time being we are using as it is, but soon we will have to
refactor.
And I think this is part of the community exchange, not only code but

Re: Cancel submit form

2010-06-29 Thread Olivier

Hi,

I use a normal button with a onClick event.
The problem with this method is when hitting ENTER, the form is not 
submitted. So I loose the normal behavior of the form.

I still would like to use the onSubmit event of the form.

Have you tried with GWT 2.1 M1 ?

 Hi,
 
 I'm trying to cancel a submit form event and it doesn't seems to work.
 I'm using UI Binder,  this is the code I have :
 
 @UiHandler(form)
 void onSubmit(SubmitEvent event) {
 
GWT.log(Submit);
event.cancel();
 
 }
 
 For some reason the form is still submitted, I'm not sure why.
 
 Has anyone experienced this before ?

 Hi Everybody,

 I'm currently developping an MVP based app mainly inspired by the

 http://code.google.com/intl/fr/events/io/2009/sessions/GoogleWebToolkitBestPractices.html
 and also the article
 http://code.google.com/intl/fr/webtoolkit/articles/mvp-architecture.html.

 Here is an example of the code I would like to simplify using DI (as I
 understand, GIN could do some part for me) :

 public class SearchPresenter implements Presenter {

public interface Display {
HasClickHandlers getSearchButton();
}

Display display;

public void bind(Display d) {
display = d;
display.getSearchButton().addClickHandler(new ClickHandler()
 {

@Override
public void onClick(ClickEvent event) {
doSearch(event);
}

});
}


 As I understand, perhaps I am wrong, GIN could do the bind() for me ?
 But, how should I use GIN for that (if it is really suited for this) ?

 Thanks for your help !

Re: GWT Application does not work in IE8 at all?

Hi,

You added a catch block. What is the caught exception? Can you add a

 Hi there,

 Hopefully you guys can help me. I have built a GWT application which

 Line: 408
 Char: 12
 Error: Exception thrown and not caught.
 Code: 0

 When I locate that line in the generated file (this was all done with
 the -PRETTY argument for easy reading) I find it's on this line where
 the finally is at:

 function entry0(jsFunction, thisObj, arguments_0){
   var initialEntry;

     return jsFunction.apply(thisObj, arguments_0);
   }
   finally {

     --entryDepth;
   }

 }

 The problem is that this is not code generated from my client side
 java - it seems to be GWT's own generated code.

 As a test I added an empty catch block - that now stops Internet
 Explorer from complaining but still doesn't load my application up at
 all. All that loads is the surrounding html and images and a blank
 space where my app should be.

 Has anyone experienced this before? Any ideas on how to tackle this?

 Any information will be greatly appreciated!

Re: Million access to GWT Appl ??

Yes, but think that user will ask for more interactivity... resulting
in more requests. But, of course, bandwidth, CPU and memory will be
saved. They will be saved more is a good architecture is used like a
Rest-like server, I think.

On Jun 22, 10:33 am, Chris Boertien chris.boert...@gmail.com wrote:
 Your essentially asking the wrong question. I think its better to
 think of by how much will GWT or products similar to GWT reduce the
 load on a server.

 You have to consider the fact that every user accessing a traditional
 website backed by a templating engine involves alot of resources for
 each and every request for new information.

 Take a web forum for example. I think they are probably one of the
 least effecient communication mediums and would be very interesting to
 see a GWT implementation of one. With the status quo web forum you
 have full page loads happening every single time a user wants to move
 around on the forum. And if the user wants to see what is new on the
 forum... you guessed it, full page load.

 Now, if you consider all the ways that having most of the web forum on
 the client side and using much more lightweight RPC calls to get new
 info (and ONLY new info) there would be quite large improvements. I
 wouldnt be suprised if the resource requirement of a GWT based web
 forum dropped the load on even the most highly active forums by
 upwards of 80%, and probably more if you really took the care to setup
 some proper caching. But regardless of how the server resource load
 would drop, just the bandwidth drop alone would be a 100% win.

Re: Dynamic Module Loading

If your need is only to define new view (with few logic), maybe using
a descriptive language will be better. You can write a templating
engine using GWT like a XUL interpreter or something like that. This
is not the best approach for optimized JS (file size, speed...) but
may be the best compromise. I think GWT compilation is too heavy to be
done on server, and worse, on the fly.

Re: Dynamic Module Loading

I don't know the full story, but maybe the problem is not a technical

they must keep their technology.

Re: Modify Java source file at compile time, possible?

Kevin,

It depends one the which generator can know which interface.

If the generators can know both interfaces, you can create only one
generator. All code generator is pushed to sub classes like
IntrerfaceAWriter and InterfaceBWriter. The generator looks for
several interfaces from the marker interface and call the
corresponding writers.

If one generator (generatorB) can know the other interface (intefaceA)
but not the reverse, it can add a field like:

private InterfaceA wrapped = GWT.create(InterfaceA.class);

Then it implements all InterfaceA's methods and forward call to the
wrapped field.

If none of them can know the other interface (like generators from two
frameworks), you can create an InterfaceC that extends InterfaceA and
InterfaceB. You add a generator that proxy all call to some wrapped
field like in the previous case, but for the two interfaces.

Do you like it?

Then, associate a generator for sub-types of MagicClass and use
GWT.create to instantiate a new Foo.

GWT.create(Foo.class);

So your generator will be called. It can generate a FooImpl class that

Where Log.log print some logs and SecurityContext.checkAuthorized

 Hi,

 I know GWT can generate Java source code with deferred binding. But
 sometimes, I don't want to generate a new implementation, but based
  on
some
 annotations, I want to have the ability of injecting code at compile
time.

 e.g., with the class below

 public class Foo {
   @Log
   public void bar() {
     @CheckPermission
     dosomething();
   }

 }

 At compile time, I want to have the ability to get the annotations
available
 on items, and inject code according to my application logic. So here,
  the
 compiler should see:
 public class Foo {
   public void bar() {
     log(begin);
     if (hasPermission()) {
       doSomething();
     } else {
       error();
     }
   }

 }

 with the extra code being injected. I'm wondering if anything in GWT
allows
 me to do that?

Re: how to enable scrolling for app using DecoratedTabPanel?

Hi,

There is two type of layouts: RIA-like and web-page-like. The RIA-like
layout is done using the layout panels. The app stretch to the whole
available space. There is no scrollbars. The web-page-like layout is
done using HTML tags (and some standard panels). The app don't
stretch. If the content is larger than the viewport, scrollbars
appears, like in traditional pages.

Looking at the first screenshot, here is my proposal:

1) The main panel is a DockLayoutPanel attached to RootLayoutPanel.
2) The north slot contains the header.
3) The center slot contains a TabLayoutPanel.

But when you show data (list, form...) you may have no enough space to
show all. Here you start to use web-page-like layout. So:

4) The contain of the contact tab is a LayoutPanel with four slot:
Tighformat, the list, Detail view, Relations.
5) Tighformat, Detail view and Relations are standard panels
(FlowPanel) into ScrollPanels. If there not enough space, a scrollbar
will appear.
6) The list is some sort of DockLayoutPanel with the headers top, the
navigation buttons bottom and the contains of the list in the center
with a scrollbar is needed. The exact implementation depends on the
used widget for the list (SmartGWT, GXT, gwt-incubator...)

Hope this helps.

Think also to invert the color between selected tab and not selected
tab. When i saw the screenshot, I thinking that blue tabs are not the
current tab and white one are the current... The current tab must be
the lighter.

what do you mean with your suggestion to use a dockpanel instead of a

 The latter sentence is not completly true.
 A LayoutPanel does not calculate its size from children.
 Especially it does not grow when the children grow.

 A Layoutpanel needs to be told which size it has.
 The possibilities are:

 a) to set height and width explicitly (what you notice)
 b) to grow and shrink with its parent (what you missed)

 What is the best way to implement that ?
 1) only one couple of presenter/view for object1 and this couple

Re: Using the addAndReplaceElement to add Widgets

Hi,

What do you think about that way :

SearchForm.ui.xml
g:FormPanel styleName=search form action= method=post
  g:HTMLPanel
fieldset
  ...
/fieldset
  /g:HTMLPanel
/g:FormPanel


SearchForm.java
public class SearchForm extends Composite {
  interface Binder extends UiBinder...
  private static final Binder binder = GWT.create...;

  private FormPanel form;

  public SearchForm() {
form = binder.createAndBind(this);
initWidget(form);
  }
}


This ensures you don't break the event handling. You can also replace
input.. by g:TextBox... and button... by g:Button These
two classes generate clean HTML.

If you really want to continue with your way, you have to deal with
widgets internal like sinkEvents, adopt, onAttach...

                                 /div
                         /fieldset
                 /form
   /g:HTMLPanel

 And then I've created a Widget that extends the FormPanel and tried,
 mapped it and tried to use the getWidgetContainer inside the
 panelSearch.java to replace it with my class that extends the
 FormPanel. It replaced well but I can't get the events ( like
 submitHandler ). How can I do that? Is there a way?

Re: Problem with RequestBuilder

Hi,

Configure your backend server to serve the folder where your GWT
HTML page is (and the compiled JS). Then, open this page in your
browser. The URL may be something like:

http://localhost:88/mypage.html

This load the compiled version of your application. Add a parameter
named gwt.codesvr with value 127.0.0.1:9997 and the dev mode will
be used.

http://localhost:88/mypage.html?gwt.codesvr=127.0.0.1:9997

Now you can use the dev mode and have not SOP probem ;)

Re: DockLayoutPanel inside a ScrollPanel

2010-06-16 Thread Olivier Monaco

Elben,

The layout panels are made to avoid scrolling. They must have a fixed
size. They use the whole window and updates there content viewport as
the window is resized. If their content is too large to be shown, a
part of it will be hidden (http://code.google.com/intl/fr/webtoolkit/
doc/latest/DevGuideUiPanels.html).

So, as Gal said, fix the size of you DockLayoutPanel. If it's not an
option for you, you may forgot layouts. What do you try to do?

 setting the height of both panels to some pixel, but this is obviously
 not a useful solution.

Re: Bookmarklet with GWT

2010-06-14 Thread Olivier Monaco

My linker generate .cache.js files instead of .nocache.js (in fact it
use XsLinker). Then, it create a bootstrap script (the .nocache.js)
derived from the one for XsLinker.

But there's a limitation. The bootstrap needs the base path of the GWT
folder (the one with .cache.js files). To find it, the bootstrap needs
to find the script tag of itself. You must add an id attribute to it
containing the name of your module followed by Loader. If your
bootstrap script is myscript.cache.js, the id must be
myscriptLoader.

Then your bookmarklet is:
javascript:(function(){var
%20t=document.createElement('script');t.id='myscriptLoader';t.type='text/
javascript';t.src='http://www.server.com/myscript.nocache.js?
_bk_='+t.id+'_nocache='+(new

Re: Bookmarklet with GWT

2010-06-13 Thread Olivier Monaco

Hi Kerem,

Your way to create a bookmarklet is not trivial. If you want a easier
way, you can try my bookmarklet linker (http://code.google.com/p/tyco/
source/browse/#svn/trunk/tyco-gwt/src/main/com/googlecode/tyco/gwt/
bookmarklet). Then, you just have to write a bookmarklet that load
the .nocache.js file.

 And Yes bookmarklets could be a BigDevil. These kind of tools must be
 open source. They are only JS, They are already open source. But I
 will share the gwt codes as soon as possible.

   how do you create a bookmarklet in gwt? like a casual gwt project?

 Yes it is casual gwt project. but you need to do something after
 compile java codes. There is some trick about server
 communication(http://code.google.com/webtoolkit/doc/latest/tutorial/
 Xsite.html). I explained it in my blog post, but I will give more info
 about it...

 Because I need a translate tool like that :) and am I misunderstood

I'm okay for blocking one part of the application or the whole for

Re: Using Javascript Overlays vs. Manually setting up POJO instances?

You have also some framework like piriti allowing easy mapping between
JSON and Java object. But I don't like them because their overhead. I
use another approach.

My model is made of interfaces. I share the interfaces between the
server and GWT. For GWT, I have a generator that automatically
implements the interface as a wrapper around the JSO. This wrapper is
a zero-overhead implementation (just method forward).

You can find my generator here if it can help you:
http://code.google.com/p/tyco/source/browse/trunk/tyco-gwt/src/main/com/googlecode/tyco/gwt/tikray

Either way, ouch.

Re: Using JavaScript Overlay Types for Nested JavaScriptObjects

Hi,

Imagine you have this in your HTML page:
-
html
  ...
  script
window.data = { prop1 : { prop2: 42 } };
  /script
  ...
/hmtl
-

First create a JSO for the prop1 value:
class InnerJSO extends JSO {
  protected InnerJSO() {}
  public native int getProp2() /*-{ return this.prop2; }-*/;
}

Second create the outer JSO (the data value):
class OuterJSO extends JSO {
  protected OuterJSO() {}
  public native InnerJSO getProp1() /*-{ return this.prop1; }-*/;
}

Finally create a method that returns data:
public native OuterJSO getData() /*-{ return $wnd.data; }-*/;

Okay? Do you need more explanation?

Re: Using Javascript Overlays vs. Manually setting up POJO instances?

My TNativeList is a list-like wrapper around a JS array (http://
code.google.com/p/tyco/source/browse/trunk/tyco-gwt/src/main/com/
googlecode/tyco/gwt/tikray/client/TNativeList.java). It is used by
TList, a List implementation that maps a JS array to a List without
(too much) overhead.

The following unittest is an example of ListString member:
http://code.google.com/p/tyco/source/browse/trunk/tyco-gwt/src/test/com/googlecode/tyco/gwt/tikray/client/collection/GwtTestCollection.java
. I plan to reduce this code be providing a default list where the
list if null.

Currently, my code allows the members of:
- primitive types (int, boolean...)
- wrapper types (Integer, Boolean...)
- String
- Collection/List of wrapper types or String
- Collection/List of JSO
- Collection/List of TObject (something generated by my generator)

Adding Map is not so hard, I just have no need it before ;).

Re: Using jqPlot library (javascript chart) with the MVP pattern

Because the array is bound to the sub-frame used by GWT.

When you create an array using [], the Array function is called. This
is the same as new Array(). Then the following condition returns
true: [].constructor == Array.

But, there is an Array function for each frame. If you create an array
in one frame, and use the same comparison in another, it will returns
false.

You must create your array using new $wnd.Array(). That's another
reason to do a real wrapper ;).

Re: CSS theming

David,

I use something like that. To easy manage my CSS class names, I use a
generator similar to the CssResource-generator. I define an interface
extending Identifiers with one method for each CSS class name:

interface MyCssClasses
extends Identifiers
{
  public String firstClass();

  public String secondClass();
}

My generator create an implementation that returns the name of the
method for each one. This allow refractoring and avoid typo-error. I
also added some annotation to allow name override (@Identifier) and
case transformation (@Transform). I also use it each time an
identifier is needed.

You can find my code here:
http://code.google.com/p/tyco/source/browse/#svn/trunk/tyco-gwt/src/main/com/googlecode/tyco/gwt/user

Hope this helps,

 I also don't want just global CSS though, I want CSS scope as local as

 idea about how to organize our CSS to do this:

 1) Shared CSS file - contain some styles that are shared across all widgets
 like fonts
 2) Local CSS stuff - stuff that applies only to 1 widget or so, this will be
 inside the widget's ui.xml file, or in a separate css file and referened
 from the ui.xml file
 3) Theme CSS file - there will be several, all of which extend from some
 interface that defines classes that can be then modified by a theme's css
 file

 So within any one ui.xml file I might be referring to some local css, the
 shared css, or the theme's css.

 Any comments?

Re: JSONParser can't parse some unescaped unicode characters

Hi,

JSONParser must only be used with trusted JSON because it uses
eval(). Thing about using a real JSON parser. This will avoid
problem like this one.

As a JSON parser example, you can see my port of the JavaScript parser
from json.org: 
http://code.google.com/p/tyco/source/browse/#svn/trunk/tyco-gwt/src/main/com/googlecode/tyco/gwt/client/json

It uses the native JSON parser if available, and uses a JavaScript
implementation otherwise. I know someone try to do something similar
into GWT but had some issues. I hope a true JSON parser will come
soon.

   - Chrome 5.0 and FF 3.6: error with character 0x2028 and 0x2029
   - IE 8.0: no error

   It works if I escape the characters with \u2028 and \u2029.

  This is because GWT for now uses eval() to parse JSON, and U+2028
  and U+2029 are line terminators in JavaScript (per spec).
  Quoting ECMASCript 5, which defines JSON.parse:
  JSON uses a more limited set of white space characters than
  WhiteSpace and allows Unicode code points U+2028 and U+2029 to
  directly appear in JSONString literals without using an escape
  sequence.

   I'm using Jackson on server-side to generate the JSON string which is
   sent to my GWT application and it doesn't escape by default these
   characters. As a workaround, I've implemented a Jackson custom
   serializer.

  Jackson is right, as these aren't special characters in JSON, but on
  the other hand, it could escape them to cope with web apps that eval()
  the result instead of JSON.parse()ing it.

 if someone is interested by the workaround, it is now on Jackson 
 wiki:http://wiki.fasterxml.com/JacksonSampleQuoteChars

 there are also several issues regarding escaping in JIRA:

Re: Using jqPlot library (javascript chart) with the MVP pattern

Try to replace your $.jqplot by $wnd.$.jqplot. The window object
where the JSNI is run is not the main window. You can access it
through $wnd.

 Finally I think I'm going to try with the JavaScriptObject class,
 cause I can cast it in Element object.

 public class CallChartView extends Widget implements

         }

         public native JavaScriptObject createChart() /*-{

                 line2 = [25, 12.5, 6.25, 3.125];

                 plot = $.jqplot('chart1', [line1, line2], {
                        legend:{show:true, location:'ne'},title:'Bar
 Chart',
                        series:[
                              {label:'Profits', renderer:
 $.jqplot.BarRenderer},
                              {label:'Expenses', renderer:
 $.jqplot.BarRenderer}
                        ],

                        }
                 });
                 return plot;
         }-*/;

 }

 But now I have an error from the GWT console : $ is not defined. I
 have already tried to change the javascript configuration but the
 problem is always present.

Re: Using jqPlot library (javascript chart) with the MVP pattern

Okay, next try (I've read your post this time ;)).

You want to cast a JavaScriptObject to an Element. You can... but it's
a bad idea. A Widget needs an Element because it offer some DOM
manipulation. Providing a JSO may lead to strange behavior. You need
to write a clean GWT wrapper around jqPlot.

For your current problem, $ is not defined, are you sure you have
included the jqPlot library? Using the FireBug's console, can you
access the $ (try typeof($))?
