Re: RequestFactory updating issue: update entity which has fields that are not listed in the proxy interface

RF won't (shouldn't) *set* the installationDate to null. If it's set to 
null, it's because when you retrieve the Contract by ID (assuming it's an 
EntityProxy), i.e. in Contract.findContract static method or a Locator's 
find method, you retrieve an object that has a null value in 
installationDate.

Problem with getting height of element

2011-05-25 Thread Globee

Hi,

I am currently working on my own implementation of scrollable panel because 
I want to have opportunity to customize style of scrollbar but I encountered 
some problem. I want to hide scrollbar when it is not needed. Idea is 
simple. I listen for LoadEvent fired by content of this panel and when I 
received it I compare height of content with height of wrapping panel. If 
content has height grater than wrapper, I hide scrollbar but here emerges my 
problem. I need opportunity to define height of wrapper in css in 
percentage. In this case when I check height of wrapper after receiving 
LoadEvent it's always 0px thus scrollbar is always visible even if it is 
not needed. Of course after rendering wrapper has height computed 
accordingly to percentage value and it's not 0px. I tried to get height of 
this wrapper by js function getComputedStyle() but it didn't work, it still 
returns 0px. Maybe someone has other idea how I can hide this scrollbar or 
get computed height of this wrapper?

Re: new html page wizard broken ?

2011-05-25 Thread Tor Pedersen

I get the same thing on Windows... there is allready a registered
issue @ http://code.google.com/p/google-web-toolkit/issues/detail?id=6338

Hopefully they will fix this pronto, as a gwt project isn't going to
fly very far without an html page. As a workaround I guess you can
create a new project with the sample code, and then copy the contents
of the html and css pages from there

Dealing with XSRF/CSRF

2011-05-25 Thread HelperMethod

Am I correct, that if I pass a self-generated sessionID with every RPC
request, and only check this sessionID instead of the one passed in
the cookie header, the session can't be hijacked by malicious sites? I
know that you should also send this sessionID in the cookie and then
compare it with the one sent with every request to detect an XSRF
attack but doing it my way should at least protect against XSRF
attacks, doesn't it?

EDIT

I know that GWT 2.3 takes care of XSRF by providing XSRF Token
Support. Sadly I'm stuck with GWT 2.2 and so have to deal with it by
myself.

Отг: Re: RequestFactory updating issue: update entity which has fields that are not listed in the proxy interface

2011-05-25 Thread Miroslav Genov

I think that I found where is the problem. The problem is that I'm 
initializing my id locally and RF is checking whether you are doing that by 
using the EPHEMERAL placeholder. 

  /**
   * A placeholder value for {@link #clientId} to indicate the id was not
   * created locally.
   */
  public static final int NEVER_EPHEMERAL = -1;

So I have to load object first then I have to update it. The following 
change makes the things working:

 CustomerRequestFactory.CustomerRequest request = rf.customerRequest();
request.findCustomer(1l).to(new ReceiverCustomerProxy() {
  @Override
  public void onSuccess(CustomerProxy entity) {
CustomerRequestFactory.CustomerRequest editRequest = 
rf.customerRequest();

entity = editRequest.edit(entity);

entity.setName(test test);
entity.setVersion(2l);

editRequest.store(entity).to(new ReceiverVoid() {
  @Override
  public void onSuccess(Void response) {

  }
}).fire();
  }
}).fire();

Are there are any workarounds which I can use to lie RF that request was 
loaded ?

In my case object is loaded as in the example, but proxy values are copied 
from one proxy to another due some old bugs with RF  Editor integration. It 
seems that this copy functionality is broking everything.

Re: MVP pattern uncaught exception

2011-05-25 Thread Jordi Planadecursach

Problem identified. Thanks for the help.

The activity was injected to the View after its construction while the
activity was requested by the class inicializator.
I am forced to pass the activity in the constructor of the view.

Is that a good practice?

ant build using javac/gwt shows errors when eclipse/gwt build does not

2011-05-25 Thread sldahlin

In the gwt project in Eclipse uses Eclipse to compile the java code
using the automatic build feature then the gwtc compile using ant does
not show any problems. If however, I clean all the existing .class
files and then execute an ant build which runs javac and then gwtc, I
get problems with my JPA entities such as:

[ERROR] Line 12: No source code is available for type
javax.persistence.metamodel.SingularAttribute; did you forget to
inherit a required module?

I should note that I am making sure that the classpath for the ant
build is using the same exact set of libraries that is present in the
Eclipse Java Build Path. Since Eclipse does not apparently provide a
log of the build process I cannot determine if there is some
divergence. Since the projects have to build on Hudson on the build
server (which has the problem I outlined) I cannot rely on a dev
machine doing the .class generation and then gwtc doing the gwt
compilations.

I wish to note that the jpa/dto entities are contained inside the
project and are not a separate project. We have been using this
technique for a while but suddenly this issue showed up. I presume
either Eclipse is using jars different than the ones I have in the WEB-
INF/lib (even though they match the java build path) or it is some
ordering issue

can't get Audio to replay.

2011-05-25 Thread dani shaulov

I want an audio file to play every time I click a button. Can't find a
way that works.
Tried:

final Audio boom1 = Audio.createIfSupported();
boom1.addSource(Resources.INSTANCE.boom1().getUrl(),
AudioElement.TYPE_MP3);
boom1.load();
Button b1 = new Button(Boom1);
b1.addClickHandler(new ClickHandler()
{

@Override
public void onClick(ClickEvent event)
{
boom1.setCurrentTime(0);
boom1.play();
}
});
RootPanel.get().add(b1);

But it doesn't seem to work. Furthermore, More testing revealed that
the SetCurrentTime method doesn't seem to work at all.

When clicking the button, the file plays once and that's it, never
plays again.

*Resources.INSTANCE.boom1() is a function in a client bundle that
retrieves mp3 file.

SimpleEventBus: How to add a handler and fire an event for it when nested in a parent handler?

2011-05-25 Thread Panam

In my parent handler, I'd like to initiate an rpc call and react to
it when it arrives.
Thus in short, the setup is as follows

thisMethodIsCalledBytheParentHandler(){
HandlerRegistration messageRetrievedHandlerRegistration =
myEventBus.addMessageRetrievedHandler(new MessageRetrievedHandler() {
@Override
public void onMessagesRetrieved(Message event) {
//do something
messageRetrievedHandlerRegistration.removeHandler();
}
}
fetchMessage();
}

fetchMessage(){
myService.getMessage(id, new
DefaultAsyncCallbackListEventMessageDTO() {
public void onSuccess(Message myMessage){
//do someting
myEventBus.fireEvent(new messageRetrievedEvent(id, 
myMessage));
)
}

The addMessageRetrievedHandler is actually enqueueAdded in the
SimpleEventBus (because firingDepth is  0):

SimpleEventBus(line 166.., GWT 2.1.1 )
 private H extends EventHandler HandlerRegistration doAdd(
  final GwtEvent.TypeH type, final Object source, final H
handler) {
if (firingDepth  0) {
  enqueueAdd(type, source, handler);
} else {
  doAddNow(type, source, handler);
}

Problem: The handler is added AFTER the messageRetrievedEvent is
actually fired, because both, adding the handler and firing the
corresponding event is taking place in the context of a parent handler
(i.e. firingDepth is  0).

Any ideas on how to get around this? Tried some Scheduler experiments
but this did not really seem to help...

Thanks
panam

Generating GWT widgets based on an XML template

2011-05-25 Thread Arshad

Hi all,

I'm pretty new to GWT, so please bear... Coming from a Struts
background, GWT concepts takes a lot of getting used to :)

I have a requirement of defining a user interface in a custom XML
template, process it to generate a technology independent generic
component tree, and use this tree to generate various different user
interfaces (e.g. Swing, GWT, JSF, etc...). To get this going, I make
use of reflection to transfer values from the generic component to the
Swing/GWT/JSF component.

I'm in the process of developing the GWT part, and feel like theirs
two ways of approaching this:
1. Do only the XML processing in the server side. The client makes an
RPC call and retrieves the generic component tree in to the client
side in order to generate the GWT widgets. This doesn't seem to be an
option since GWT doesn't support reflection on the client side.

2. Do both the XML processing and the GWT widget generation on the
server side. The client makes an RPC call and retrieves the generated
GWT widgets. This also doesn't seem to be possible... may be because
it the widgets are not serializable?

I would really appreciate any input regarding this. Is there anyway I
can generate the GWT widgets on the server side and retrieve it from
the client side? Or is there any other way I can approach this
problem?

Thanks in advance,
Arshad

Re: GWT Designer + GXT - Palette don't display GXT components

GXT is only supported for GWT Java UIs.

UiBinder does not provide an API for non-standard parsers, so, in

GXT works fine using GWT Designer and GWT Java UIs.

Re: Help with WindowBuilder Pro XWT Application Wizard

2011-05-25 Thread Eric Clayberg

Please note that XWT is an Eclipse technology that is unrelated to
GWT. As such, this is the wrong place to ask any questions about it.

If you have questions about XWT or how to configure a project to use
XWT, they should be asked in the Eclipse XWT forum.

For questions specifically about WindowBuilder, you should post those
to the Eclipse WindowBuilder forum.

Selecting TextInputCell

2011-05-25 Thread tjmcc18

I have a CellTable which makes use of TextInputCells to allow the user
to edit data.  I would like this to behave in a spreadsheet like
manner such that the user can select the various textboxes and make
changes as they see fit.  However, the default behavior for selecting
the textboxes is not desirable.  When a user first selects a textbox,
it receives focus and the user can edit the data.  When the user then
tries to select another textbox, the previous textbox loses focus but
the newly selected textbox does not receive focus.  Clicking on the
box again gives it focus.  In essence it takes two click to select the
textbox.  This is very annoying.  I believe the first click possibly
selects the cell, but I'm not sure.  Does anyone know how to get
around this?

download gwt application data

2011-05-25 Thread barz1


The company I work for is switching its front end to a gwt application
and I was wondering if it is possible to write a script (whether with
bash and wget or cURL, or java or anything) that enables me to
download the actual content of the gwt web application. Because right
now if I try with a command such as wget I just download a page with
some javascript functions, but none of the actual page content (what I
am interested in). I am on the QA side so I guess I am wondering if it
is possible to perform such a task without having direct access to the
developers code. Thanks!

Re: GWT Designer not working?

2011-05-25 Thread gwa

Either is really a initialization timeout because your computer is
slow / ui is large
or you can check if you havn't a proxy defined at the system level (on
windows, check IE network connection). (gwt designer try to connect to
a localhost port, but if a proxy is defined, sometime designer send
your request to the proxy)

Re: download gwt application data

2011-05-25 Thread David Chandler

GWT apps manipulate the browser's DOM directly via Javascript, so there is
no HTML layout. Is that what you mean by page content? However, you can
use the Snapshot Firefox extension to save the DOM structure at a given
point in time as an HTML file.

HTH,

2011-05-25 Thread Gabriel

Hi,

I can think of two options to implement what you want:
1) On the server side generate DTOs that represent the UI structure
and on the client side read them and build the UI accordingly.
2) Generate pure HTML on the server and use it as the value of an HTML
widget.

The choice depends on what exactly you need from the client side. You
should minimize the use of widgets as much as possible, and use them
only if you need to capture events. Otherwise it is recommended to use
HTML.

 Hi all,

 I'm pretty new to GWT, so please bear... Coming from a Struts
 background, GWT concepts takes a lot of getting used to :)

 I have a requirement of defining a user interface in a custom XML
 template, process it to generate a technology independent generic
 component tree, and use this tree to generate various different user
 interfaces (e.g. Swing, GWT, JSF, etc...). To get this going, I make
 use of reflection to transfer values from the generic component to the
 Swing/GWT/JSF component.

 I'm in the process of developing the GWT part, and feel like theirs
 two ways of approaching this:
 1. Do only the XML processing in the server side. The client makes an
 RPC call and retrieves the generic component tree in to the client
 side in order to generate the GWT widgets. This doesn't seem to be an
 option since GWT doesn't support reflection on the client side.

 2. Do both the XML processing and the GWT widget generation on the
 server side. The client makes an RPC call and retrieves the generated
 GWT widgets. This also doesn't seem to be possible... may be because
 it the widgets are not serializable?

 I would really appreciate any input regarding this. Is there anyway I
 can generate the GWT widgets on the server side and retrieve it from
 the client side? Or is there any other way I can approach this
 problem?

 Thanks in advance,
 Arshad

StockWatcher javascript compile does not open browser

2011-05-25 Thread Bob

I am working my way through the STockWatcher tutorial at
http://code.google.com/webtoolkit/doc/1.6/tutorial/compile.html

but have a problem at this section: 2. testing in web mode

Everything works fine in host mode, but the instructions say when you 
compile to JavaScript (the red tool box with a G on it icon), after it 
successfully compiles, and browser window will open.  The browser window is 
not opening.

I checked under PreferencesGeneralWeb browser, both internal and external 
set to chrome, and it seems to be fine.

Any ideas?  I am on a MAc

Thanks

PreloadedTable alternative - GWT Incubator is death?

2011-05-25 Thread Go2one

Hi everyone,

because of performance issues we are using the PreloadedTable instead
of FlexTable. No I read, that GWT Incubator is death? Is there any
alternative to the PreloadedTable?

By the way: Why does PreloadedTable not support the method
getCellForEvent(event) (like the FlexTable)? How can I fetch the cell
or row, that was clicked at the UI?

Thanks and best Regards!

Re: Generating GWT widgets based on an XML template

2011-05-25 Thread Arshad Nadheem

Thanks for the response Gabriel... it's the 1st option that I'm
looking for. Generating HTML is not an option for me, since each of my
widgets need to be self-contained components. So, the 1st option is
the way to go for me.

But this is where my problem starts... I'd love to use reflection to
populate the widgets. I.e for each getters in my DTO, I try to invoke
the corresponding setter in the widget (if exists). E.g.: If my
ButtonDTO has a getHeight(), I'd check if the Button widget has a
setHeight(). If so, I'd call setHeight() of the Button widget with the
value of buttonDTO.getHeight().

The easiest way to do this is through reflection, so that I won't have
to do the above manually for each property. Of course some values
cannot be set in this manner... that has to be dealt in the normal
way.

So, if I follow the approach that you mentioned as option 1, I won't
be able to use reflection, right? Any workarounds?

Thanks again,
Arshad

 Hi all,

 I'm pretty new to GWT, so please bear... Coming from a Struts
 background, GWT concepts takes a lot of getting used to :)

 I have a requirement of defining a user interface in a custom XML
 template, process it to generate a technology independent generic
 component tree, and use this tree to generate various different user
 interfaces (e.g. Swing, GWT, JSF, etc...). To get this going, I make
 use of reflection to transfer values from the generic component to the
 Swing/GWT/JSF component.

 I'm in the process of developing the GWT part, and feel like theirs
 two ways of approaching this:
 1. Do only the XML processing in the server side. The client makes an
 RPC call and retrieves the generic component tree in to the client
 side in order to generate the GWT widgets. This doesn't seem to be an
 option since GWT doesn't support reflection on the client side.

 2. Do both the XML processing and the GWT widget generation on the
 server side. The client makes an RPC call and retrieves the generated
 GWT widgets. This also doesn't seem to be possible... may be because
 it the widgets are not serializable?

 I would really appreciate any input regarding this. Is there anyway I
 can generate the GWT widgets on the server side and retrieve it from
 the client side? Or is there any other way I can approach this
 problem?

 Thanks in advance,
 Arshad

Re: Selecting TextInputCell

Try clicking though and editing the TextInputCells in the showcase.
It takes multiple clicks... how can I get around that?

 it receives focus and the user can edit the data.  When the user then
 tries to select another textbox, the previous textbox loses focus but
 the newly selected textbox does not receive focus.  Clicking on the

Re: Generating GWT widgets based on an XML template

2011-05-25 Thread Gabriel

Indeed you can't use reflection, but note that a vast majority of the
widget properties are actually style (as in CSS) properties, so you
can take advantage of it. I'm thinking in this direction: in your DTO
have a MapString,String where the keys are style properties and the
values are the style values, and on the client side iterate over the
map and for each entry call
Widget.getElement().getStyle().setProperty(key, value). You can do the
same with attributes, this time call
Widget.getElement().setAttribute(key, value). And the last thing you
have to deal with is innerText (or innerHTML). So you can write a
generic mechanism that handles styles, attributes and innerText and
that should cover everything.

On May 25, 7:26 pm, Arshad Nadheem arshadnadh...@gmail.com wrote:
 Thanks for the response Gabriel... it's the 1st option that I'm
 looking for. Generating HTML is not an option for me, since each of my
 widgets need to be self-contained components. So, the 1st option is
 the way to go for me.

 But this is where my problem starts... I'd love to use reflection to
 populate the widgets. I.e for each getters in my DTO, I try to invoke
 the corresponding setter in the widget (if exists). E.g.: If my
 ButtonDTO has a getHeight(), I'd check if the Button widget has a
 setHeight(). If so, I'd call setHeight() of the Button widget with the
 value of buttonDTO.getHeight().

 The easiest way to do this is through reflection, so that I won't have
 to do the above manually for each property. Of course some values
 cannot be set in this manner... that has to be dealt in the normal
 way.

 So, if I follow the approach that you mentioned as option 1, I won't
 be able to use reflection, right? Any workarounds?

 Thanks again,
 Arshad

  Hi,

  I can think of two options to implement what you want:
  1) On the server side generate DTOs that represent the UI structure
  and on the client side read them and build the UI accordingly.
  2) Generate pure HTML on the server and use it as the value of an HTML
  widget.

  The choice depends on what exactly you need from the client side. You
  should minimize the use of widgets as much as possible, and use them
  only if you need to capture events. Otherwise it is recommended to use
  HTML.

Re: download gwt application data

OK, that's quite different. In that case, you'll want to use the browser's
Developer Tools or something like TamperData (FF extension) to inspect each
request and copy the request URL into your script. With these tools, you'll
also be able to see the server response, which you can cut and paste to a
file.

Re: Problem install


It appears you're either using an old update site, and/or possibly an old 
version of eclipse (3.3 is no longer supported by the GPE team).  I'd 
consider redoing the install into a fresh eclipse (preferably 3.6).  The 
basic GPE update instructions are located here:

http://code.google.com/eclipse/docs/download.html

I don't know off the top of my head if/which eclipse is installed as 
standard 10.04 LTS packages, but you can get newer versions of eclipse here:

http://www.eclipse.org/downloads/

If you don't know which version you want, the Compare Packages link 
towards the top of that page will help you decide.  I generally end up using 
either the Classic or JEE versions myself.

You will need to do something like this.


public class ExposeImpl implements IsSerializable {

  @SuppressWarnings(unused)
  private ConstraintViolationImpl? constraintViolationImpl;

  @SuppressWarnings(unused)
  private PathImpl pathIpml;

  @SuppressWarnings(unused)
  private HashSet? hashSet;
}


And then Create a dummy method like the following in your RemoteService


 ExposeImpl dummy();





I am working on a simpler solution.

Re: Help with WindowBuilder Pro XWT Application Wizard

Can you please observe Window Builder Pro project's website here:

Also the Community link, links to this forum.

 Please note that XWT is an Eclipse technology that is unrelated to

 If you have questions about XWT or how to configure a project to use

 For questions specifically about WindowBuilder, you should post those

Re: Big Daddy example problems

2011-05-25 Thread bbgott

I have not had the Fatal Exception issue, but I have had other
problems with it, when developing on Ubuntu linux.  When I try the
example on my Mac, it works.  I have been able to narrow it down to
the fact that the example attempts to connect to 127.0.1.1: for
debugging with a local app engine instance.  Upon examining the
Util.java file, around the 190 line area, it says to create an assets/
debugging_prefs.properties file with the url of the debug app engine
server in it.  I tried doing that, but everytime I ran the code, it
would revert the url back to 127.0.1.1:.  The only way that I have
been able to get the code to run on linux is to hardcode the url of
the dev app engine into the Uitl.java file.  This seems to be a bug in
the App engine connected project.  I have scoured the project settings
as well as the other eclipse settings and can not come up with a
reason for why it keeps reverting that file.

Re: using GWT with flex?

Well the suggestion  was for the Integrating Flex with GWT part.

If you come from Flex learning GWT should not  be a  big problem because the
development model is very similar.
The official GWT Documentation is always a good point to start:
http://code.google.com/webtoolkit/doc/latest/DevGuide.html
And if you are really really stucked there is a guy called *Thomas
Broyer*here in the community. You cant miss him :)

Making a GWT RPC call from an AS3/MXML based  Flex application is not that
easy and adds a lot of  overhead to your application.

We had the same issue with one of our Flex applications. This is one of the
reasons that motivated me to create a GWT API for Flex, so one could use
Java everywhere instead of mixing MXML/AS3(Flex UI), JavaScript(External
Interface to communicate with the GWT ) and Java(GWT +  backend)

If your Flex application is MXML/AS3 based the best way should be to use
something like Blase DS.

If you want to use a GWT API to build a Flex application  you can  have a
look at gwt4air.

Best,

Alain

2011/5/25 Seth Hollyman s...@jujufrog.com

It appears you're either using an old update site, and/or possibly an old
version of eclipse (3.3 is no longer supported by the GPE team). I'd
consider redoing the install into a fresh eclipse (preferably 3.6). The
basic GPE update instructions are located here:

http://code.google.com/eclipse/docs/download.html

I don't know off the top of my head if/which eclipse is installed as
standard 10.04 LTS packages, but you can get newer versions of eclipse here:

http://www.eclipse.org/downloads/

If you don't know which version you want, the Compare Packages link
towards the top of that page will help you decide. I generally end up using
either the Classic or JEE versions myself.

Re: using GWT with flex?

2011-05-25 Thread Jay

Thanks for response. We are already using blazeds to communicate with our 
remote spring services. Our present architecture:
Flex talks to backend java objects using spring blazeds.

I want to incorporate ajax so What I had in mind is
Flex mxml/as screen invokes JavaScript invokes java backend?
Would that be correct?

Thanks

Re: using GWT with flex?

What exactly  do you mean  with incorporate ajax ?
Do you mean making async  call to the server ?
If  yes cant you do that with Blase DS ?

Like i said before i dont know  if the road mxml/as -External Interface -
js -  gwt - backend  and  back is effective
because  you are adding  a lot of overhead just to call methods in the
backend.

Re: using GWT with flex?

2011-05-25 Thread Jay Roy

let me explain with a simple example
We have a flex screen with a data grid. The data in data grid is populated
with java collection. The java collection contains stock data which comes
from backend.  In the backend every 0.5 second the stock data in collection
is updated(we get market feed of data).

so every 0.5 second we need to refresh the flex data grid and update it with
the backend data.

So the question now is we need to make a asynch call every 0.5 sec to fetch
the updated data.

I am using blazeds to get the java collection but i dont think blazeds can
be used to make asynchronous calls. That is where we want to use ajax to
make the asynchronous call every 0.5 sec.

thanks.

Dock Layout Panel

2011-05-25 Thread Doug

Good Evening,

I am trying to design an app using DockLayoutPanel (using the example
here:http://code.google.com/webtoolkit/doc/latest/
DevGuideUiPanels.html) and I can't seem to get the panel to work.
When I run this code in the development server all I get in the
browser is a blank page with header in the upper left.  Both IE and
Chrome display the exact same page.

Can anyone tell me what I am doing wrong?

Thanks,
Doug


DockLayoutPanel p = new DockLayoutPanel(Unit.EM);
p.addNorth(new HTML(header), 2);
p.addSouth(new HTML(footer), 2);
p.addWest(new HTML(navigation), 10);
p.add(new HTML(Content));
RootPanel.get().add(p);

Re: can't get Audio to replay.

2011-05-25 Thread John LaBanca

The first thing to check is that the http headers include the correct mime
type. The version of Jetty that GWT uses doesn't return the correct
mime-type by default. Take a look at the mime-types defined in the web.xml
file of the mobilewebapp sample for an example workaround:
http://code.google.com/p/google-web-toolkit/source/browse/trunk/samples/mobilewebapp/war/WEB-INF/web.xml

Hopefully that will work, but I also ran into a similar problem recently.
Loading the file from the file system worked, but loading it from dev mode
(with app engine enabled) caused it to play only once and not be seekable.
My only lead was that the HTTP headers contained cache-control: private,
which might cause the browser to not cache the file, and thus make it
unseekable. I think you can work around this using Filters with appengine,
but I haven't tried it.

Thanks,
John LaBanca

Re: running GWT compiler low priority

Depending on how you're calling the compiler, there may be several options 
available to you:

1) start the compiler at an elevated nice level (nice first, not renicing 
after start)

2) Tweak the jvm arguments so the compiler is less greedy with resources

3) Consider tweaking the GWT compiler options for faster, less optimized 
compile times if you're just iterating quickly


The following URL has a lot of information on getting better mileage out of 
GWT development, including many of the options you can pass both to devmode 
and the compiler (compiler args are at the bottom):

Re: Forwarding all calls to the initial page


You might want to check out the javadoc for 
com.google.gwt.user.client.Window.Location (has helper methods to get access 
to the URL, hashes, and GET parameters).  If this is a precursor to a more 
advanced application, you may want to take the time to learn how GWT's 
history mechanism works (store and retrieve application state through URL 
hash tokenization), and patterns that build upon it like Activities  
Places.

GWT's javadoc viewer can be found here:

exactly. yes i think u r right i can do it using timer object. so i am

I would be curious to see what an AJAX framework like GWT can do which flex
cant.

 let me explain with a simple example
 We have a flex screen with a data grid. The data in data grid is populated
 with java collection. The java collection contains stock data which comes
 from backend.  In the backend every 0.5 second the stock data in collection
 is updated(we get market feed of data).

 so every 0.5 second we need to refresh the flex data grid and update it
 with the backend data.

 So the question now is we need to make a asynch call every 0.5 sec to
 fetch the updated data.

 I am using blazeds to get the java collection but i dont think blazeds can
 be used to make asynchronous calls. That is where we want to use ajax to
 make the asynchronous call every 0.5 sec.

 thanks.

 What exactly  do you mean  with incorporate ajax ?
 Do you mean making async  call to the server ?
 If  yes cant you do that with Blase DS ?

 Like i said before i dont know  if the road mxml/as -External Interface
 - js -  gwt - backend  and  back is effective
 because  you are adding  a lot of overhead just to call methods in the
 backend.



   2011/5/26 Jay jagger...@gmail.com

   Thanks for response. We are already using blazeds to communicate with
 our remote spring services. Our present architecture:
 Flex talks to backend java objects using spring blazeds.

 I want to incorporate ajax so What I had in mind is
 Flex mxml/as screen invokes JavaScript invokes java backend?
 Would that be correct?

 Thanks

Well the suggestion  was for the Integrating Flex with GWT part.

 If you come from Flex learning GWT should not  be a  big problem because
 the development model is very similar.
 The official GWT Documentation is always a good point to start: 
 http://code.google.com/webtoolkit/doc/latest/DevGuide.html
 http://code.google.com/webtoolkit/doc/latest/DevGuide.html
 And if you are really really stucked there is a guy called *Thomas
 Broyer* here in the community. You cant miss him :)

 Making a GWT RPC call from an AS3/MXML based  Flex application is not
 that easy and adds a lot of  overhead to your application.

 We had the same issue with one of our Flex applications. This is one of
 the reasons that motivated me to create a GWT API for Flex, so one could 
 use
 Java everywhere instead of mixing MXML/AS3(Flex UI), JavaScript(External
 Interface to communicate with the GWT ) and Java(GWT +  backend)

 If your Flex application is MXML/AS3 based the best way should be to use
 something like Blase DS.

 If you want to use a GWT API to build a Flex application  you can  have
 a look at gwt4air.

 Best,

 Alain

 hi guys

 I need to learn GWT and impliment a simple solution using GWT. I come
 from flex background.
 can anyone point me what the important concepts in GWT is? and in what
 order do i learn?

 Goal:
 we are currently developeing a trading app using flex screens but we
 want to use ajax framework GWT to make the asynchronous backend calls
 to our spring-java backend.
 (Is using flex  Fabridge an option to integrate GWT with flex?)

 any help greatly appreciated
 thanks.

Re: Generating GWT widgets based on an XML template

2011-05-25 Thread Arshad Nadheem

That's awesome... I never tough in the lines of setting CSS into widgets...
Thanks a lot!
So this means that I can have my reflection thing going on the server side -
to populate the Map with key/value pairs of the fields in the DTO..!

Cheers,
Arshad

 Indeed you can't use reflection, but note that a vast majority of the
 widget properties are actually style (as in CSS) properties, so you
 can take advantage of it. I'm thinking in this direction: in your DTO
 have a MapString,String where the keys are style properties and the
 values are the style values, and on the client side iterate over the
 map and for each entry call
 Widget.getElement().getStyle().setProperty(key, value). You can do the
 same with attributes, this time call
 Widget.getElement().setAttribute(key, value). And the last thing you
 have to deal with is innerText (or innerHTML). So you can write a
 generic mechanism that handles styles, attributes and innerText and
 that should cover everything.

  Thanks for the response Gabriel... it's the 1st option that I'm
  looking for. Generating HTML is not an option for me, since each of my
  widgets need to be self-contained components. So, the 1st option is
  the way to go for me.
 
  But this is where my problem starts... I'd love to use reflection to
  populate the widgets. I.e for each getters in my DTO, I try to invoke
  the corresponding setter in the widget (if exists). E.g.: If my
  ButtonDTO has a getHeight(), I'd check if the Button widget has a
  setHeight(). If so, I'd call setHeight() of the Button widget with the
  value of buttonDTO.getHeight().
 
  The easiest way to do this is through reflection, so that I won't have
  to do the above manually for each property. Of course some values
  cannot be set in this manner... that has to be dealt in the normal
  way.
 
  So, if I follow the approach that you mentioned as option 1, I won't
  be able to use reflection, right? Any workarounds?
 
  Thanks again,
  Arshad

   Hi,
 
   I can think of two options to implement what you want:
   1) On the server side generate DTOs that represent the UI structure
   and on the client side read them and build the UI accordingly.
   2) Generate pure HTML on the server and use it as the value of an HTML
   widget.
 
   The choice depends on what exactly you need from the client side. You
   should minimize the use of widgets as much as possible, and use them
   only if you need to capture events. Otherwise it is recommended to use
   HTML.

   Hi all,
 
   I'm pretty new to GWT, so please bear... Coming from a Struts
   background, GWT concepts takes a lot of getting used to :)
 
   I have a requirement of defining a user interface in a custom XML
   template, process it to generate a technology independent generic
   component tree, and use this tree to generate various different user
   interfaces (e.g. Swing, GWT, JSF, etc...). To get this going, I make
   use of reflection to transfer values from the generic component to the
   Swing/GWT/JSF component.
 
   I'm in the process of developing the GWT part, and feel like theirs
   two ways of approaching this:
   1. Do only the XML processing in the server side. The client makes an
   RPC call and retrieves the generic component tree in to the client
   side in order to generate the GWT widgets. This doesn't seem to be an
   option since GWT doesn't support reflection on the client side.
 
   2. Do both the XML processing and the GWT widget generation on the
   server side. The client makes an RPC call and retrieves the generated
   GWT widgets. This also doesn't seem to be possible... may be because
   it the widgets are not serializable?
 
   I would really appreciate any input regarding this. Is there anyway I
   can generate the GWT widgets on the server side and retrieve it from
   the client side? Or is there any other way I can approach this
   problem?
 
   Thanks in advance,

Re: Dock Layout Panel


Use RootLayoutPanel instead of RootPanel in your example code when attaching

Hello!
I have a problem with my GWT application. I deploy on Jetty server and
it runs. But when I perform a server call (class on server package of
GWT), the server returns an error message. The message is:

However, the server returns a 200 code that is OK.
I have updated the browser, clear up browser cache and recompiled the
application, but it does not run. What is the solution for that??
Thanks in advance!

[gwt-contrib] Re: Editor framework and submitting object graphs

Actually, the Editor framework underwent a complete rewrite between 2.2 and 
2.3. There are only few visible changes though: introduction of EditorDriver 
base interface (with setConstraintViolations, so error reporting is now 
available on SimpleBeanEditorDriver too), EditorVisitor and 
HasRequestContext.

Yea, that makes sense that its a chrome bug. I'll just change the css in my 
application to not use any opacity to get around the issue. I think my main 
concern was that most people aren't used to opacity in their scrollbars. 
When I looked at it initially, it just didn't feel like any experiences I've 
had on the web previously. 

Is there any bug tracker you don't know by heart? :)
