Is it possible to _replace_ element with my widget?

[Jaroslav Záruba]

Hi

I know how to insert widget into element...
RootPanel.get("placeholder").add(new MyWidget("hello"));

But is it possible to *replace* element with my widget?

I already tried following...
Element placeholder = RootPanel.get("debatePlaceholder").getElement();
placeholder.getParentElement().replaceChild(commentPanel.getElement(),
placeholder);

But the widget seems to be dead, i.e. it does not receive ClickEvents. :(

Regards
  J. Záruba

This is the javadoc for History.getToken() in 2.1:

http://google-web-toolkit.googlecode.com/svn/javadoc/2.1/com/google/gwt/user/client/History.html#getToken()
Gets the current history token. The handler will not receive a
ValueChangeHandler.onValueChange(com.google.gwt.event.logical.shared.ValueChangeEvent)
event for the initial token; requiring that an application request the
token explicitly on startup gives it an opportunity to run different
initialization code in the presence or absence of an initial token.

So guess is not deprecated.

Yep, now u tell... There is another way to access the location, but i
never used.

BTW about the question about how to compile it. You can use ant or

Re: GWT 2.1.0 M1 and Roo development lifecycle. What would you do?

[Jaroslav Záruba]

I don't dare teach anyone Roo, I'm yet to try it myself. :) Let me only tell
you that I'm having pretty similar concerns to yours whenever I hear "code
generation". And after watching the video I know I will try it, it has
impressed me enough.

ClickHandler on ListBox. Problems in Safari and Chrome

[chfr]

Hello,

I'm working on a small GWT application, but I'm experiencing a
problem.

When I add a ClickListener to a ListBox there is no functionality in
Safari and limited functionality in Chrome(both browsers in their
newest versions).

However in IE and Firefox everything is working fine so I'm wondering
where the problem is...

I wanted to ask if someone knows a workaround so that my application
can support all browsers.

best regards

chfr

Re: GWT 2.1.0 M1 and Roo development lifecycle. What would you do?

[André Moraes]

Jaroslav,

But how can I control the merge process?
In my case the code is generated, than i can edit make any changes in
the generated code (which will be preserved by the safe-code-marks)
and then the GWT compiler (or any other compiler) will compile the
code that i wrote.

I don't really know/use Roo, but I used some code generation tools
before, so excuse me for any noob comment on the Roo subject.

Well not exactly like that but it does not mess-up your code irreversibly.

Roo keeps your code untouched. It stores the modifications elsewhere and

Re: GWT 2.1.0 M1 and Roo development lifecycle. What would you do?

[André Moraes]

I'm not using the integration with Roo, but I dislike the idea of
having a tool that after generating my code difficult to customize the
generated code.

A while ago I wrote a code generator that allows reuse of code and
Retrieval without losing the customizations made.

Through some markings (in comments) in the code the user can define
the points where he wants to insert customizations.

Thus, the tool does not enter the path and the user has more control
over the generated code and customizations future.

Follow the link from the tool:
http://code.google.com/p/am-code-generator/

The documentation on using the tool is not very good, but it is quite
simple.

I'll try to commit some examples of how to generate code using the
tool.
Any comments or criticism is welcome.

I am available for any questions.

Re: java.util.Map with Javascript Overlay example?

[André Moraes]

In JavaScript world, almost everything is a Dictionary.

If you simply need a dictionary, just use a JavaScriptObject.
Here is a example:

public final native void setValue(String key, String value) /*-{
this[key] = value;
}-*/;

private native static JavaScriptObject _createInstance() /*-{
var obj = new Object
return obj
}-*/;

I think the _createInstance isn't required, but I don't tested.

java.util.Map with Javascript Overlay example?

[rhodebump]

Can anyone point me to an example in which someone uses Javascript
Overlays to create a java.util.Map.  I've tried, but keep getting a

 java.lang.ClassCastException:
com.google.gwt.core.client.JavaScriptObject$ cannot be cast to
java.util.Map


Is it even possible?  Or am I limited to using a JsArray?

Re: Compile and Run gwt web application from Command Line

History.getToken() isn't deprecated?!

I use the History.addValueChangeHandler.

History.addValueChangeHandler(new ValueChangeHandler() {

@Override
public void onValueChange(ValueChangeEvent 
event) {
location = event.getValue();
}
});

But it only works with the information after the "#", not with the
parameters in the QueryString part of the URL.

Re: Invoke SOAP Web Service from GWT on the server side.

[AgitoM]

Hi Stefan,

Thanks for your reply. Well thats what I indeed thought as well.
But for some reason invoking a service using AXIS2 is causing me a
problem, hence I decided to ask if there was any restriction.
Well, I will just keep on trying and getting it to work.
Once I do, I will post a solution here.

In the meanwhile, if anyone has a good idea on how to do it, feel free
to post here.

Re: Calling RSS service in GWT from the server side

[AgitoM]

Managed to solve the problem. Used a different object to connect to
YAHOO.
Don't know why my first solution didn't work though.

I do not have access to my corrected code currently, but will post the
right solution here as soon as possible.

Assuming the element is  or 

HTML html = HTML.wrap(DOM.getElementById("GWTIDSOFELEMENT"));
html.addClickHandler(new ClickHandler() {
  @Override
  public void onClick(ClickEvent event) {
System.out.println("CLICK");

Re: Compile and Run gwt web application from Command Line

[fmod]

Hi, from the command line:
start http://somesite.com/MyPage.html

If you want to pass some parameters, you can use the address.
start http://somesite.com/MyPage.html?param1=blah¶m2=boo

Somewhere in the onLoadModule() you will need to check
History.getToken()
and parse it.

Regards
Fran

Need to build a WYSIWYG XML editor

[NS Gopikrishnan]

Hi all,

I want to develop a WYSIWYG XML editor for a custom schema.
I am new to GWT.
I wanted to know whether GWT will be  the right framework for that.

* Whether XML DOM builders are available.
* I need to provide the view side using CSS.
* Validation of XML for every change in nodes.
* view the XML while editing the view (Not necessarily simultaneously)

Thanks in advance !

GWT 2.1.0 M1 and Roo development lifecycle. What would you do?

[Marco De Angelis]

I've been giving a closer look at GWT 2.1.0 M1 and Expense application
lately, as the best way to be educated after Google I/O 2010 sessions.
In your opinion, how long a real-world application shall be coupled
with Spring Roo infrastructure/annotations?

It's obvious that the default views generated by Spring Roo will be
replaced by custom views developed with specific application logic.
Even if you're a CSS wizard, at some point in time you would need a
custom behaviour. I can see the following approaches:

1) Remove all references to Roo. The Expenses application has, in
fact, removed the AspectJ extensions, all Roo annotations and just
reused the skeleton of Entity+Record+Places+Activities as basis for
custom views. If you have to add a new field or a new entity after
abandoning roo, you're own your own.

2) Like 1), but keep the original Roo project somewhere in parallel.
If you have to modify something, you can still use Roo to generate new
classes and fields scaffolding, and then manually copy/paste/adjust in
the real-world application. Not so integrated, but it may work if your
views and logic change more often than the model does.

3) You keep roo as part of the development cycle. You place your
custom views in separate package, and add your own modules that use
your own widgets instead of the scaffolding ones. In this way, roo can
always rebuild the entire scaffolding without interfering with your
code. You still have to manually adjust your custom views to handle
new/removed/modified fields and entities. Very nice integration, but
you need to know exactly what Roo is going to ovewrite when things
change.

4) I have a little knowledge of Roo, so there might be extension
points that I'm not aware of. In that case there might be other ways
to add your own views.

I'm tempted to think approach 2) is the classical good-enough
compromise, but I'm interested in other people's opinion.

Re: Web server magic?

[anjan bacchu.dev]

Hi fmod,

  Thank you.

"If you
open the Run Configurations dialog from eclipse it will uncover part
of this magic."
I was wondering how to change the port on which jetty listens and the above
dialog did the trick.

I run the Fiddler http proxy for intercepting the traffice between chrome
browser and Jetty. Fiddler listens at port  and since jetty also listens
at port , this clashed and I could NOT get Fiddler to work. Now, I've
moved Jetty to use 8889 (hope that does NOT clash with another program that
is installed in my box :-)  )

BR,
~A

I my case it was the following line in the
Main.gwt.xml file:


I read somewhere that with this property better stack traces are

There were some additional lines but removing this one solved the
problem.

I had no problem with that in hosted mode but in web mode i got a

Integration of servlet from another GWT module

[remip73]

Hi,

I've 2 GWT module, module 1 and module 2.
Module 1 inherits module 2.
Module 2 has an entry point and when it has finished its startup tasks
it must load some services from module 1.
Module 2 and module 1 have some servlets, they are all declared in
web.xml from module 1.
I run module 1 in GWT development mode.

How can I process to integrate properly module 2 and module 1?

For now module 1 is unable to find Servlet class from module 2
(java.lang.ClassNotFoundException at launching), I've included
module2.jar in build path : it doesn't work. I've also tried to copy
content of war/web-inf of module 2 in war/web-inf of module 1, it
works but for debugging it's not easy!!!

Thanks for your help.

Problem to load data from Database

[Lucasj85]

Hi all, i'm Gianluca and i start from a few week to study Google Web
Toolkit.

In this days i'm trying to load a data from a FireBird Database. But i
have  a problem, can't load!!!
Ok, if i create a projet in java , i can normally extract a data from
my database( creating connection  with JDBC).

I also copy the class created in java for connection to the database
in my GWT project, but the error that Eclipse show me in the console
is:

org.firebirdsql.jdbc.FBDriver

I show you my  GWT project:



The main class call ChiamataServe.javar ( italian name , i'm italian):

Re: Does a private variable in Java stays private when compiled to javascript?

[Sripathi Krishnan]

I think you missed Thomas' post. You *CAN* keep your variables private, its
just you have to use a different linker. Its just a minor change to your
gwt.xml, and with that your entire script will be private.

Re: Best way to Deserialize JSON String to Java Object

[Chris Boertien]

All good points, but I think you guys are totally missing the point.
He was taking a POJO and converting it to JSON for transmission using
GWT-RPC, which is completely redundant since GWT-RPC can simply send
the POJO and handle all the messy bits for him.

Simple is better...

Re: Best way to Deserialize JSON String to Java Object

[Gal Dolber]

I think the best you can do is a generator that creates an overlay for that
pojo and a utility class to convert a json string to the pojo.

The interface will look like this:

public interface Json2Pojo {
POJO fromJson(String json);
}

And the steps will be:

   1. Create an POJOOverlay from the json string
   2. Instantiate a POJO
   3. Call all POJO setters with POJOOverlay getter
   4. Return the POJO

And the gwt compiler will inline that for you.

Re: Creating custom 'elements' for UiBinder, like in DockLayoutPanel

[Lukas Laag]

Hi Graham,

You should look at this thread which contains interesting information
on how to create custom element parsers:
https://groups.google.com/group/google-web-toolkit-contributors/browse_thread/thread/4d79f729030527c5/181973c17d16cbc0?lnk=gst&q=custom+element+parser#181973c17d16cbc0

My understanding of the key points is:
a/ You officially cannot create your own element parser (there is no
publicly supported API for that)
b/ However, because GWT is open source, you can easily patch one or
two classes, put them at the head of your classpath and create your
own element parsers (though with no guarantee that they will not be
broken by future GWT evolutions).
c/ rjrjr mentions a possible public API for this in a later release,
possibly 2.1. However, if you listen to this webcast (http://
code.google.com/events/io/2010/sessions/gwt-ui-overhaul.html) from IO
2010, the possibility for a public API seems more remote (somebody
asks the question at the end of the session)

I have used this myself extensively to map SVG tags in UiBinder. If
you are interested, you can look here (http://www.vectomatic.org/lib-
gwt-svg/uibinder-integration-with-lib-gwt-svg) for an article about
this work and here (http://www.vectomatic.org/mvn-sites/lib-gwt-svg/
xref/org/vectomatic/dev/svg/impl/gen/SVGButtonBaseParser.html) for
source code.

Re: Stop Cell Selections in a Grid

[Stefan Bachert]

>~Scott

Hi Scott,

I do not answer to personal mail without a support contract ;-)


The mentioned idea is, that a selection starts with some kind of mouse
click.
When you catch this click and avoid default handling, this may
succeed.
However, a specific "selection" is not known to me.

Your problem is a general one.

The google group app behaves the same as you describes. You ca do
selection regardless of you application. In such cases you will detect
that we are still using browser which allows to copy and paste html.

On thing i detected recently is that a absolute positioned panel (like
LayoutPanel) do limit the selection across widget.

However, maybe the easiest might be to ignore this requirement as it
seems to lead to a bunch of hacks.

central configuration file (xml) - where to place?

[Magnus]

Hi,

I want to have a central configuration xml file to store things like
database connection. The file should be accessible from the client and
the server code.

Where should I place this file and how can I access it (are java
properties supported in client code?)?

Thank you
Magnus

Re: Best way to Deserialize JSON String to Java Object

[Peter Simun]

Hi Jose,

Piriti project looks great for your needs. If you would like to
customize deserialization process (with custom instantiators and
deserializers) you can also use acris-json project. You can find
details here:
http://code.google.com/p/acris/wiki/GWTJsonizer

(Project is based on JSONParser from GWT which internally use eval
function)

Only with using annotations you can get powerfull piece of
functionality in JSON parsing mechanism. For example this project was
used for deserialize JSON reponses from Google Youtube API in gwt-
youtube-api.googlecode.com project.

Re: enable/disable widgets?

[Trevor Skaife]

The setEnabled method is in the FocusWidget which I'm assuming all of
your input widgets extend. So just cast all of the widgets in your
form to a FocusWidget and then you can enable/disable them.

it does not have the desired effect. see the diff

Re: Invoke SOAP Web Service from GWT on the server side.

Hi Agito,

when you on the server side, you can do anything you can do with java.
No limits from GWT applies.

With other word, you may ask any other java group, too

Hi Zubair,

when you want to change the gwt themes at run, have a look on the

The showCase is doing such a thing.

Re: Does a private variable in Java stays private when compiled to javascript?

[Shedokan]

So i'll guess I'll have to make my app completley in javascript, I
hope that someday in the future GWT would allow things like this.
In javascript it is possible to have a completley private variable,
like so:

myApp = function(){
  var privateVariable = "private";

  // Setter and getter
  this.setPrivate = function(var){
privateVariable = var;
  };

  this.getPrivate = function(){
return privateVariable;
  };
};

and as far as I know there is no way to access the privateVariable
unless your'e using something that is not javascript.

Well, thanks anyway.

Re: Vertical/Horizontal split panel min size?

[Stefan Bachert]

Hi Tony,

look at the source code, try to catch the event which changes the
splitter position and do them not to allow to exceed certain values.

I have seen such a behaviour with gwt-mosaic.
Maybe you want give mosaic a try.

Re: Best way to Deserialize JSON String to Java Object

[Harald Pehl]

Hi Jose,

you could take a look at Piriti: http://code.google.com/p/piriti/.
It's an XML / JSON mapper for GWT which maps JSON data from the server
to POJO on the client.

- Harald

P.S. At the moment Piriti uses the "eval" function to parse JSON. This
will be changed in the next release, so that the internal JSON parser
is used.

Re: Best way to Deserialize JSON String to Java Object

[Chris Boertien]

Shouldn't have a problem sending a HashMap back and forth. As far as i
can tell GWT has a fairly complete implementation of the Java
Collections API, and all of which are Serializable, so there shouldn't
be any issues. I haven't used it for much more than Lists so there
might be quirks I haven't come across yet.

Re: Best way to Deserialize JSON String to Java Object

[Jose Luis Estrella Campaña]

Hello There !

I believe what Chris says is totally right, I should just use a
regular Java Object, I was mistaken when I thought I had to do JSON
parsing on the server side.
Now, I would like to know if a HashMap containing Strings only is
serializable ? Could I send it from the client to the Server and Back
(specially back)?

Thank you very much in advance !

Jose.

Making the "back" button go even further back in history?

[dduck]

Hi,

I have this unusual problem.

I have a form page that redirects to a results page that auto-
redirects to my GWT application page. Now, if the user presses the
browser "Back" button, he goes back to the auto-redirect page, which
is not what he would expect - he wants to get to the form page, so TWO
steps backwards.

Is there any way to make that happen?

Regards,
  Anders

Re: GWT project with multiple pages

[Brian Reilly]

The application that I'm working with has been around for a long time
and has used a few different web frameworks. The last one we adopted
(Tapestry 4) took that "reverse" approach of being the primary
framework and providing an adaptor for the previous framework. This
time around, I'm not looking to replace or re-implement the overall
application structure, especially the menu system that's currently in
place.

I agree that it's not optimal and not taking full advantage of what a
GWT application could be. However, it's more like having a collection
of separate GWT applications that are deployed together. The reason
for putting them all in one GWT module is to optimize compile time.
There are some parts of GWT compilation that would be repeated
unnecessarily if they were in separate modules. I know this because we
implemented 2 features that way before realizing it would be a
problem.

One upside of my situation is that, while we have a lot of existing
features implemented in other frameworks, we may eventually be able to
leave those behind. Once we have enough of the new requirements
implemented in GWT, we may be able to essentially extract an entirely
new application where GWT is the primary framework, which will be
reasonably easy to do. The other way to look at it is that there's no
way we could adopt GWT at all if we weren't able to take this
incremental approach.

-Brian

Re: Creating custom 'elements' for UiBinder, like in DockLayoutPanel

[Will]

I want to create the same UiBinder support for custom elements as
well.  Can anyone point us towards an example in the GWT source so
that we can see how  is implemented and get an idea on how
we can create similar elements?  If I don't hear back I plan to create
a different widget for each custom element and have an onAttach( )
method that will throw an exception if the widget is placed outside of
the correct context.  I think that will behave similar to 
but I imagine GWT uses something more robust.

Re: History and server call.

[Ravi Sharma]

Thanks Tristan for your comments. Your comments kicked my thoughts
running again :).

Let me explain how non readable code/decoupling view from presenter
etc can make life easier in terms of designing.(for the Records, i
always like Readable code)

Currently our view and presenter are dependent on each other, although
we use interfaces but still they are tightly bound that view know
there is one presenter for him(implementation may be different by
injection). I have seen the Contacts project code provided by Google
and see presenter(via dispaly) and view(via presenter) call each other
directly.

Now lets say i am writing a wizard screen or my one click will update
2-3 view/panels in my screen.

Ok i will take example where one click will update 2-3 section of
whole page which are basically different view and each will have
presenter.

Say ViewA is header (PresenterA is its presenter)
ViewB is left side panel,(PresenterB is its presenter)
ViewC is Bottom Panel(PresenterC is its presenter)
ViewD is right side Panel(PresenterD is its presenter)

Now there is button/Link on ViewA which say clickMe. On clicking this
ViewB should load some data from server and ViewC should hide some
data, viewD also load some data.

Now as per MVP/Contact project style.
My ViewA should be injected with PresnterA,PresnterB,PresenterC and
PresenterD

And onClick event i will call methods of each presenter, which
eventually raise the required events and which may create history and
then do the server calls. Technically everything is ok(normal java
inetrface/class calls tree), but problem occurs when something
changes. Say now PresenterB doesnt need to update any thing when we
click the same button. At that time you may want to remove PresnterB
from ViewA as whole, you dont want to keep such code as it(PresenterB)
will never be used in ViewA. Or say some new ViewE came up somewhere
and you want to update this via PresenterE, so you need to inject
presenterE dependency in ViewA so that ViewA can a make call like
PresenterE.doSomethingForMe(). Lots of code changes which could be
avoided by just using EventBus.


Say OnClick we just raise an event HEY_BUTTON_CLICKED_ON_VIEW_A and
presenterB,PresenterC,PresnterD will be interested in this event
initially. Once PresenterE will come then PresnterE will be interested
in that too.And when PresnterB says i dont need to update, it will
just stop listening to that event. But i will never touch ViewA class
or any other presenter at all.

And also i looked into AppController class in Contacts project  and it
looks to be controller it self for views and presenter.
I should say its not MVP but its MVPC

Now with using EventBus for all Communcation i am just assesing the
existance of presenter it self(just to make a go call ?). Why do i
need presenter at first place. Just to be tight bound with View??. SO
that if tommorow my site/application goes for mobile i write seprate
presenter which will be bind to seprate view as per Mobile screen. Why
not i just write seprate view and use EventBus.

Basically with in Client(between UI events/activities and server calls
at client side), i am trying to have RPC calls kind of style. UI
request client side code with an event and get response with another
event. I feel its just MVE (Model View Event), no controller and no
presenter.


Does it make sense?
Ravi.

RE: Moving to gwt 2.0.3

[Ricardo Manuel Saraiva]

Nevermind... It was my web.xml ... thanks ;)

Subject: Moving to gwt 2.0.3

Hi,

I'm moving my project to the new version of gwt.

I'm having some problems. It gives me the following error:

"message /zonaReservada/scripts/gwt.Foo/common

description The requested resource (/zonaReservada/scripts/gwt.Foo/common) is 
not available."

I'm using module inheritance. It was working fine in the previous version. Is 
there anything new I have to consider?

Here are the modules:

Common.gwt.xml







Adv.gwt.xml






Foo.gwt.xml








And this is my html file:

http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd";>


   
   


   
   



In the previous version I only moved the file gwt.js to my scripts folder. In 
this version I'm moving all the compiled files.

Can anybody help?

Thanks,
Ricardo Saraiva

Thanks Jaroslav.
I was not able to find a replacement for that deprecated Listener.

Moving to gwt 2.0.3

[Ricardo Manuel Saraiva]

Hi,

I'm moving my project to the new version of gwt.

I'm having some problems. It gives me the following error:

"message /zonaReservada/scripts/gwt.Foo/common

description The requested resource (/zonaReservada/scripts/gwt.Foo/common) is 
not available."

I'm using module inheritance. It was working fine in the previous version. Is 
there anything new I have to consider?

Here are the modules:

Common.gwt.xml







Adv.gwt.xml






Foo.gwt.xml








And this is my html file:

http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd";>


   
   


   
   



In the previous version I only moved the file gwt.js to my scripts folder. In 
this version I'm moving all the compiled files.

Can anybody help?

Thanks,
Ricardo Saraiva

Vertical/Horizontal split panel min size?

[Toni]

Hello,

Does anyone know whether it is possible or not to set a minimum split
bar position to the Vertical or HorizontalSplitPanel so that the user
cant drag it to the border of the panel? If not, is there a way to do
it?

Cheers!
