Well that s not true :)
Thomas Broyer is everywhere in this forum. He might not be "officially" from

Did you had any issue that  could not be answered ?

Re: CellTree with CellTable nodes

When I use a classic Tree widget, it works fine with my CellTable as a

Re: GWT 2.1 vs GWT 2.2 and this forum

2011-04-29 Thread Javier

I agree that Thomas is very supportive but I miss more participation
from other GWT members. If you look to the group information you can
see that the GWT member (appart from Thomas) who has published more
messages in the last month is David (Chandler) with 16. The GWT team
is free to participate or not in the forum, but I believe that an
active community is really important for a technology to be
successful.

Compared to other programming groups, GWT has a reduced number of
messages per day (maybe 20-30?). Despite of that, I see many
interesting questions not being answered.

That is just my opinion.

Re: can I send something like upload finished answere from HTTP servlet to my application ?

2011-04-29 Thread Alan Chaney

See FormPanel and  FileUpload in the java docs. The FormPanel.onSubmitCompleteHandler does exactly 
what you want. When your file has finished uploading the browser generates this event, and you can 
use it to hide your upload panel.

Extending Google GWT plugin

2011-04-29 Thread amos

Hello,
is there any way how to extend or build upon Google GWT Eclipse
plugin? I want to create some support in Eclipse that would in fact
need to create and maintain GWT project plus some additional features
(probably also having own Project Nature). Is there some API provided
by Google GWT Plugin that I could use? I have found some Extension
points in Eclipse provided by the plugin, but there is no
documentation for it.

Thanks for answer

Strange thing: when I run URL http://127.0.0.1:/Maas.html my
application works properly, but when running correct URL
http://127.0.0.1:/Maas.html?gwt.codesvr=127.0.0.1:9997 browser
shows nothing but blank screen. And the same moment I see something
like "waiting for http://gwt.google.com/missing-plugin..."; in IE's

What may be the course?

Deferred Binding error when upgrading to GWT 2.0.0

2011-04-29 Thread stockloser

I've finally hit a wall on trying to resolve this error and decided to
post here to reach out for some advice/help.

I have a GWT 1.5.3 application that works with Stripes 1.4.2
framework. In that configuration, the application compiles/runs
successfully. However, I am attempting to upgrade the application to
GWT 2.2.0 and have been running into the Deferred Binding compile
error in all post GWT 2.0 versions. I did not receive the error in any
of the pre 2.0 versions.

My setup is the following:

gwt-maven-plugin - 1.2
gwt - 2.0
stripes - 1.4.2

The specific error I receive when compiling using the maven plugin is:

[INFO][ERROR] Errors in 'jar:file:/C:/Users/Kevin/.m2/repository/
mil/whs/eccs/eccs-commons-client/4.0/eccs-commons-client-4.0-
sources.jar!/mil/whs/eccs/model/gwt/organization/service/
GwtOrganizationServiceWrapper.java'
[INFO]   [ERROR] Line 19:  Failed to resolve
'mil.whs.eccs.model.gwt.organization.service.GwtOrganizationService'
via deferred binding
[INFO][ERROR] Cannot proceed due to previous errors

The application has 7 GWT modules in the POM. The really bizarre part
of this whole issue is that the error appears randomly. Sometimes all
7 compile with no errors, other times, 5 compile, and sometimes it
fails before the first compile. So it is hard to imagine it is
actually a deferred binding exception and not something else.

I am wondering if it could be an issue between GWT 2.0 and stripes but
I am not sure. I would appreciate any help in resolving this issue.

GWT 2.2 canvas not working in IE9

2011-04-29 Thread Ulas

Hi,

I've recently been experimenting with the new canvas functionality in
GWT 2.2. My software is supposed rotate an image, which works fine in
all the (supposedly) supported browsers except IE9. More exactly the
Canvas.isSupported() method call returns false in IE9.

Has anyone else come across this problem or does anyone know why IE9
behaves this way?

Thanks!

Adding custom styles to CellTable

2011-04-29 Thread tomo2

Hello,

I have added a new style class to a row in a CellTable.  When I looked
in Firebug, the style name is being obfuscated in the generated CSS.
I have the following:

Source:
 interface MyTableResources extends CellTable.Resources {
@Source({CellTable.Style.DEFAULT_CSS, "mytest.css"})
TableStyle cellTableStyle();
  }

  interface TableStyle extends CellTable.Style
  {
  public String mytest1();
  }


  class MyRowStyle implements RowStyles
{
@Override
public String getStyleNames(ItemBuildDTO row, int rowIndex)
{
// if something...
return "mytest1";
}
}

mytest.css:
.mytest1 { font-size : 33px }


In Firebug, if I look at the HTML, the table row looks like this:



In the CSS, I cannot find a "mytest1" class anywhere, however I did
find the font-size:33px, which looks like this:

.GMHF14MCPF {
  font-size: 33px;
}


The style class is turning up as an obfuscated name.  I don't
understand why this is happening.  Any help is much appreciated.

Thanks.

Re: GWT 2.2 canvas not working in IE9

2011-04-29 Thread David Chandler

Ulas,

IE9 support is being added in GWT 2.3. With GWT 2.2, this is expected
behavior since GWT would select the ie8 permutation, for which
Canvas.isSupported() returns false. You can try it out with the 2.3
milestone release available from the GWT downloads page.

Re: URLs in Jetty

2011-04-29 Thread David Chandler

To run GWT development mode (?gwt.codesvr=...), you need to install the GWT
dev mode plugin for the browser. Ordinarily, the browser will prompt you to
do this automatically via the missing-plugin page you see in your error
message. Once this page comes up for you, just follow the prompts.

http://gwt.google.com/missing-plugin/MissingPlugin.html

Re: Trying to send image to server

2011-04-29 Thread Alan Chaney

You need to make sure that your client class is in the *server's* classpath. The exception below 
indicates that its not.



I make it a practice to have a 'shared' package hierarchy parallel to my client packages and ensure 
that:


A. shared is declared in the module gwt.xml file

B. shared is also available to the server C/P

The application is under the root, too; so you can go to

Re: GWT 2.1 vs GWT 2.2 and this forum

2011-04-29 Thread Thomas Broyer

If you look at recent participation, sure, I guess they're all working hard 
to be ready for I/O (2 weeks from now!), and they've all been working very 
hard for the whole past year (places and activities, Cell widgets, request 
factory, editor framework, safehtml!).
John Labanca however regularly answers about Cell widgets, and Eric Clayberg 
about the GPE and GWT Designer.
There's a LOT of activity in the GWT-Contributors group though, they're all 
working very hard (and recently, the Orkut team has been contributing very 
actively to UiBinder fwiw).
People in charge of "public relations" (i.e. developer advocates, like David 
Chandler) are maybe more than others busy preparing I/O.
Philippe Beaudoin having joined Google this week <
https://profiles.google.com/philippe.beaudoin/posts/PaMzvBmHEVs> maybe he'll 
dedicate some time to the GWT community (I mean, in addition to the GWTP 
one); but he'll probably not be working on GWT, so maybe not... (who knows?)

Don't mean to pester, but interestingly the subdirectory setup works on one

So, *some* web servers can handle the subfolder location.

Hi,

Check that your Hibernate files are placed in the src folder as Dolly had
mentioned.
We were working on a similar project and got similar error

Also confirm if your RPC service method can return a List as you are getting
an error in List coz for our project we colud return only a string object as
returning a list gave errors

Furthermore, writing a Query in hibernate and GWT is slightly different.I am
sending you an example of my server side query,check if you find it useful:

Query query=session.createQuery("select Empname from Addmemberserv where
Empname like :param1 and Passwd like :param2");

  query.setString("param1", input1);

  query.setString("param2", input2);



 Addmemberserv is my table name input1 and input2 are my textboxes

Re: Trying to send image to server

2011-04-29 Thread Patssay

Hi,

Thanks.
So I should have the Email class in the shared folder?
Also should the module.gwt.xml file be updated?

Actually I am trying to implement the functionality of sending email
from my gwt application.
I have the functionality up and running on the server. All it needs is
the
email addresses from the client and the image that should be sent from
the client to the server.
Hence the need for class email which has all these attributes
enclosed.
>From what I read gwt allows the user defined classes to be sent to the
server provided they are serialized.
Really appreciate your help.

mvp complex model

usually, the model in mvp is the DTO, in case the model is complex,
for example, when the validation of user input is elaborate, do you
put the validation methods in the DTO, or the presenter, or another
group of dedicated model behavior classes?

Yes - it should have:



it it.

But mainly, you need to make sure that your server-side classpath contains the file, because the 
server must be able to instantiate it.


That's what your original error seemed to imply. GWT de-serializes classes on the server by looking 
for the classname as a string in the RPC payload and then doing a 'Class.forName'. Thus the class 
must be available to the server classloader. To be honest, I don't understand why yours isn't if you 
are using eclipse, because the typical GWT project setup adds all the classes in the src folder to 
the classpath. Are you getting this problem when you are running under the debugger in Eclipse? or 
only when you deploy. If its the later, you should check that the *client* and *shared* .class files 
are present under WEB-INF/war/classes folder.

Synchronizing editor data

2011-04-29 Thread Bill T

I am using GWT 2.2.0 with RequestFactory and the Editor framework.
What is the recommended way to keep to 2 editors in sync with a shared
proxy object attribute (the same object attribute is displayed in 2
editors)?  I tried the following but ran into a few issues:

Using RequestFactoryEditorDriver I have an Editor that contains a
TabPanel with 2 tabs and contains 2 sub-editors (one for each tab).
Each sub-editor has a TextBox editor that edits MyProxy.xyz.  I tried
the following:

- added a ValueChangeHandler for the TextBox on tab 1,
onValueChange update the proxy object attribute with the value in the
TextBox and then fire an EntityProxyChange UPDATE event on the
eventBus.

- Have the sub-editor on tab 2 implement ValueAwareEditor and
subscribe() via the EditorDelegate.

This seems to work. The TextBox on the second tab was updated with the
value entered in the TextBox on the first tab. However there are a
couple of side effects:

1) When the sub-editor gets the event from the eventBus, it internally
fires a RequestFactory call to find the proxy by id from the database.
It seems that it should not need to do this but rather just refresh
the editors with the fully populated proxy object in memory. This is
why I am questioning if I am using the right approach of creating
EntityProxyChange events and subscribing.

2) Was getting an IllegalStateException: A request is already in
progress exception why I tried to do an update request later on. It
was due to a SubscriptionReceiver getting called as a result of the
update response via the EntityProxyChange UPDATE event. The
SubscriptionReceiver was referening to the current
RequestFactoryEditorDelegate that had the RequestContext from the
update request that was just fired and is now locked.  OnSuccess() in
the Receiver() was not called yet so I was not able to call edit() on
the driver which would create a new RequestFactoryEditorDelegate with
a new RequestContext passed in. To get around this I removed the
handler on the sub-editor in the flush() method since I did not need
to handle the event at that point.  Again, seems like my approach is
more complicated than it should be.

Question 1) Is there a better way to do this, essentially flush and
refresh the editors without making a request to the server? Am I
missing something?

Question 2) I followed this same pattern with a display only CellTable
editor as part of the sub-editor, but it did not get updated when the
proxy event was sent.  Is there something that needs to be done to
support the CellTable? The data was initially set correctly in the
CellTable by the driver, but it does not get updated like the other
editors.

public class SubEditor2 extends Composite implements
ValueAwareEditor{

private CellTable table = new CellTable();

// this does not get refreshed correctly but is initially displayed
correctly
@Path("someProxyList")
HasDataEditor tableEditor = HasDataEditor.of(table);

private TextBox textBox2 = new TextBox();

// this gets refreshed correctly
@Path("xyz")
final HasTextEditor xyzEditor = HasTextEditor.of(textBox2);

Thanks!

GWT RPC

2011-04-29 Thread yamit c

Hi, I'm new in the group and I have a problem with GWT, I would like
to decouple the implementation of business services and graphics
application, that is to have the services exposed in a different jar
and deploy it to another machine, I imagine something similar to when
RMI deploys a server, this is possible? or maybe I'm wrong in the
philosophy of GWT and RPC?

Re: move or not to move to Firefox 4 for GWT development

2011-04-29 Thread Tim Goeke

I am using FF4 on Mac OS X (in development mode) and I have found that
text entry boxes are broken.  When setting input focus, the
StockWatcher application does not set focus to the text box.
Furthermore, when hitting return, the char code returned is zero, not
13 as expected.  These seem to be some significant flaws in early
testing.

I have not had a chance to try FF4 under Windows.

Re: GWT Not Working for Higher Screen Resolutions

2011-04-29 Thread Trevor Skaife

That wouldn't have anything to do with GWT. It would have everything
to do with the styles and what html has been created by GWT, which you
programmed. Best thing to do is to inspect the page in the browser to
see what is causing the page to not look right. Then you should be
able to figure out what panel or table you need to change in order for
you page to flow correctly.

How to update CellTable's Header Cell based on action in data table

2011-04-29 Thread Jason

Hey everyone!  I have a question that I cannot seem to find the right
answer to.  I'm using a 2 cell tables, one for a fixed header with one
row that scrolls with the other which holds my main data rows.
Basically, I want to implement a tri-state checkbox in one of the
column headers.  I was successfully able to create a new
TriStateCheckboxCell that extends AbstractCell and it is wrapped by a
Header.  Using this class I render either an unchecked input
(checkbox) when no rows in the main table are selected, a checked
input when all the rows in the main table are selected, or an img that
represents an intermediate state of a checkbox when only some of the
rows in the main table are selected.  Using a ValueUpdater I can
select all or none of the rows in the main table when the Header's
TriStateCheckboxCell is clicked.  All of this works fine.  My problem
comes when the user selects a row in the main table and I want to set
the Header's checkbox to the intermediate state.  This calls for me to
update or re-render the contents of the Header Cell when the selection
model has been changed.  So in my SelectionModel's
SelectionChangeEvent onSelectionChange method I need to update the
cell.  This would involve calling it's onBrowserEvent or setValue
method, both of which take the parent Element as a parameter.  Only,
Cell does not contain a reference to or extend the Element class.  The
problem is that in order to re-render the Cell, I need it's parent
Element.  Obtaining this Element is not straightforward to me.  I was
able to get it by manually traversing the DOM via the
CellTable.getElement and going down, however this is not ideal.  Is
there other methodology that I am not aware of?  Am I thinking about
this the wrong way?  Thanks!

GWT Visualization Performance/Optimization

I've been using the Google Visualization XY Scatter Chart.  We want to
graph several thousand points on the chart.   I've run several
experiments now by setting up the DATA Table with various block sizes
of data.   The problem is that once there are more than a hundred
points it takes a very long time to render the graph.  I tried 2000
points and the browser locked up.

What can I do to solve this problem?   Compiler Optimization?

Re: Deferred Binding error when upgrading to GWT 2.0.0

2011-04-29 Thread stockloser

gwt-maven-plugin 2.2 is not compatible with gwt 2.0

But I did try upgrading gwt to 2.2.0 and used the 2.2.0 plugin as
well. I still received the same error.

I believe the issue lies in a change in GWT.create() in post 2.0
versions of GWT. Somehow the generated proxy is not able to locate the
RemoteServiceServlet. In our environment the RemoteServiceServlet is
implemented by a Stripes ActionBean that extends the Servlet.

In pre 2.0 implementations this was not an issue.

How do I use Tomcat rather than built-in in Development mode

2011-04-29 Thread Rob Tanner

Hi,

Code that I'm writing has to talk to a number of different servers and
I have test servers that replicate the production servers the code
will eventually interact with.  Especially with regard to long term
maintenance, I would rather not have to change the various DB, LDAP,
etc pointers every time I move a copy into production.  All the
pertinent pointers (URLs, etc) are stored as context parameters in
web.xml and with Tomcat in server.xml I can override the various of
the context parameters on my development station so I point to my test
servers and no changes would then be required when I move the code
into production.

So my question is: how do I configure GWT (the Eclipse plugin) to use
the locally installed Tomcat rather than the built-in server.  Or is
there a better was to accomplish the above while still using the built-
in server?

Thanks,

Rob Tanner

Re: Many injections of same css

2011-04-29 Thread Thomas Broyer

Using  you're creating a new CssResource (each time) 
with @Source("resources/global.css"). The rules in global.css are processed 
for each CssResource and generate different obfuscated class names (this is 
important as each CssResource could add other rules for the same class 
names, and you wouldn't want conflicts between your CssResources).
If you want to share definitions, you should use a single CssResource, 
either one that you reuse (e.g. include in a ClientBundle, and then use that 
bundle using  in UiBinder), a @Shared one that you inherit from 
(use  to point to it or an interface that extends it), 
or an @ImportedWithPrefix CssResource that you then @Import in another 
CssResource (or  in a UiBinder template).

You might be looking for the

 In your SelectionHandler, you would update the internal value of

redrawHeaders() to update the display.
(just an idea, never ever tried)

Thanks!  It took a little finagling with the arguments list to get it

Re: Does GWT 2.2 Canvas support transparency like GWTCanvas?

2011-04-29 Thread Amir

I tried using an rgba(...) string.  This works with Firefox but not Chrome, 
Safari, nor Opera.

So GWT 2.2 Canvas doesn't support colors with alpha values?  How come 
GWTCanvas does?

Please ignore.  The rgba(...) string approach works.

DialogBox.center does not center correctly

2011-04-29 Thread Magnus

Hi,

I have a problem with centering a DialogBox.

I create it, add some widgets (the size of which I set at the same
time!), and call center:
(Pseudecode)

DialogBox d = new DialogBox ();
AbsolutePanel t = new AbsolutePanel();
t.setSize("1000px","700px");
d.add(t);
d.center();

However, the DialogBox is not centered correctly. It's placed too much
to the right. (If its size is smaller, it's placed too much to the
left. #-))

I wondered if i should call forceLayout, but there is no such method
in DialogBox.

What can I do?

Thanks
Magnus
