[sreejyothi8]

Hai,

   I tried using 'il8n numberformat' to get value in Indian rupee 
format by  setting Locale as "en_IN" .But instead of returning 

   Rs 10,00,00,000.00 my code return Rs. 10,000,000.00 in this format 
   can anyone help me to get the exact result.I tried this in gwt2.5.

problem with javax.servlet.ServletContext in gwt-user.jar

[gabriele.prandini]

I'm using GWT (2.5.0) with grails (www.grails.org)
I just upgraded from grails 1.3.7 to grails 2.2.2
Tryng to compile my project i got this error

Caused by: java.lang.NoSuchMethodError: 
javax.servlet.ServletContext.getSessionCookieConfig()Ljavax/servlet/SessionCookieConfig;

you can find some information here:
http://www.javamonamour.org/2012/07/tomcat-error-on-startup.html

there seems to be a problem with the wrong version of 
javax.servlet.ServletContext in gwt-user.jar

I have, in my project some versione of the servletcontext, for example in 
grails library, that have the method public SessionCookieConfig 
getSessionCookieConfig()

but in the servletcontext in the gwt-user.jar the servletcontext doesn't 
have such method

what i can do?

Re: MVP For Popups

[Tim Hill]

Thanks Oliver, that has got me on the right track :)

Next question... When I click on the save address button (for example), the 
callback registers that the save button for address has been clicked and 
runs the required method in the callback. This then calls an async method 
in another class to save the address to a local SQLite instance. What would 
be the best way to pass back the success/failure of the database operation? 
Would it be on the eventbus, or is there a more preferred way?

Sorry for the noddy questions, but still learning!

Cheers

Tim

DataGrid Debug (missing data)

[Timothy Spear]

I am sure I am missing something very basic. :D
Anyway, here is the setup:

After login I clear all contents and create the following basic structure:

StackLayoutPanel 
LayoutPanel
TabLayoutPanel
 FlowPanel* (Place holder for future)*
 FlowPanel* (Place holder for future)*
   LayoutPanel
TabLayoutPanel
 CustomList (Widget: UiBinder Composite)
  DockLayoutPanel
  center:DataGrid
  south: HorizontalPanel
   SimplePager
   PageSizePager
 FlowPanel* (Place holder for future)*
 FlowPanel* (Place holder for future)*

Symptoms:
-- Table Header is Displayed
-- Pager stuff displayed
-- No entries in table displayed
-- Via Firefox checked DOM and no TR for any data present
-- In hosted mode, checked the return call from the server and verified the 
following:
** raw data present
** ListDataProvider has data
** calls to ListDataProvider.addDataDisplay has no errors
** Tried ListDataProvider refresh and redraw

Any other ideas or places to check?

Testing GWT without GwtTestCase

[Thad]

Can anyone clarify for me this Google testing blog entry? 
http://googletesting.blogspot.com/2009/08/tott-testing-gwt-without-gwttest.html

Model, view, presenter I think I'm clear on (ha! yeah, sure), but I'm 
trying to understand the Server.class. It's described as "a completely 
standard backend with *no dependency on GWT*." (Their emphasis.) So what is 
that? Does that mean *not* a service interface and *not* a service Impl 
class? If so, where is the RPC coming in?

What I'm trying to do--what I think many would like to do--is test RPC 
methods without the RPC delay. Right now I do that by calling my 
ServiceImpl methods in my JUnit test. This often forces me to mock an 
HttpSession object and add an extra method so I can pass that in 
(since getThreadLocalRequest() is protected). Testing through my client 
would be preferable but the delay is a pain.

Which approach is better for CellTable - TextColumn with dynamic style OR Column with ImageResource?

[andy_p1]

Hi,
 I am creating a moderate sized CellTable - 100 rows and 5 columns. In some 
of the columns I need to show small images (no text) depending on the value 
returned by the accessor method of the backing object for the row. The 
number of images are fixed i.e. the logic is basically to display one of 5 
images in a cell.

I had trouble working with a ClientBundle for my Images so as a work 
around, I did it with the following approach:

TextColumn markedColumn = new TextColumn() {
public String getValue(RowData object) {
  return "";
}
public String getCellStyleNames(Context context, RowData  object) {
if(object.getMarkedStatus()){
return "MARKED";
}
else{
return "";
}
}
  };


Now, my ClientBundle stuff is working and the following code works as well:

Column markedColumn1 = new Column(new ImageResourceCell()) {
  public ImageResource getValue(RowData object) {
if(object.getMarkedStatus()){
return ImageResourceBundle.INSTANCE.rtick(); 
}else{
return null; <-- I am not sure how to create an Empty cell. I 
guess I can return an empty/blank image here.
}
  }
};


Now, I am not sure which approach is better. I am thinking that since 
stylesheets are in generate better in performance, the first approach is 
better. Is that correct? The app will be used on mobile devices.

thank you!

Since some want the GWT conference on the west coast and some on the east, 
I say let's split the difference and meet in the middle.  I vote for Denver.

RPC Token Exceptions because Session Cookies can't be set.

[Navin Surtani]

Hey all,

I tried making my login form on my web app be protected by the XSRF servlet 
and I am getting RPC Token Exceptions thrown. I followed the implementation 
guidelines as described 
here
 and 
after I had issues I saw that someone else had the same sort of issue 
here.
 
I still have the same exception being thrown as per the second URL and I'm 
quite stuck as to what I'm supposed to do next. 

I think that I'm just not setting the JSESSIONID cookie properly. If anyone 
can help explain how and where I'm supposed to do this that would be of a 
great help. If you look at the final comment on the second link, I think I 
can have a separate servlet that can set the cookie value? However, I don't 
know if that would open the application up for a security breach.

The code that my app is failing at is here:


private void makeSecureLogin(final String krb5Name, final 
String githubName, final String pwd) {
XsrfTokenServiceAsync xsrf = (XsrfTokenServiceAsync) 
GWT.create(XsrfTokenService.class);
((ServiceDefTarget) 
xsrf).setServiceEntryPoint(GWT.getModuleBaseURL() + "xsrf");
xsrf.getNewXsrfToken(new AsyncCallback() {
@Override
public void onFailure(Throwable throwable) {
dialogBox.setText("Remote call failed");

try {
throw throwable;
} catch (RpcTokenException rpcException) {
responseLabel.setHTML("RPC Token could not be 
generated.");
} catch (Throwable other) {
responseLabel.setHTML(other.getMessage());
}
dialogBox.center();
}

@Override
public void onSuccess(XsrfToken xsrfToken) {
((HasRpcToken) loginService).setRpcToken(xsrfToken);
loginService.login(krb5Name, githubName, pwd, 
getLoginCallback());
}
});
}

private AsyncCallback getLoginCallback() {

AsyncCallback toReturn = new AsyncCallback() {
@Override
public void onFailure(Throwable throwable) {
dialogBox.setText("Remote call failed");
try {
throw throwable;
} catch (LoginFailedException lfe) {
responseLabel.setText(lfe.getSymbol());
} catch (Throwable other) {
responseLabel.setText(other.getMessage());
}
dialogBox.center();
}

@Override
public void onSuccess(KerberosUser kerberosUser) {
dialogBox.setText("Remote call successful");
responseLabel.setText("Login for " + 
kerberosUser.getGithubName() + " succeeded.");
dialogBox.center();
}
};
return toReturn;
}

Any help would be very much appreciated. 

Thanks!

Re: StackTraceElement was not included in the set of types which can be serialized by this SerializationPolicy

[Goktug Gokdogan]

StacktraceElement is marked as transient to keep it out of serialization.
Because of that, RPC system is not aware of the type. If you really want to
transfer the stack trace with your exception, then put a dummy field in
your exception:

  private StackTraceElement dummyFieldToIncludeType;

This will make StackTraceElement visible for serialization.

That is the Async interface. Technically, it still depends on GWT for the
AsyncCallback interface.
I think what they actually meant is, it doesn't depend on any native
methods so it is easy to mock.

Refactor your service out of your servlet. A common useful pattern is:

class ServerServlet extends RemoteServiceServlet implements ServerService {
  ServerServiceImpl service = 

  public void someServerMethod() {
service.someServerMethod();
  }
}
class ServerServiceImpl implements ServerService {
  // implement your logic here
}

Then write the test against for ServerServiceImpl which doesn't depend on
any servlet internals. Note that, this is pattern also useful if you need
to call ServerService at server side in production.

Offline debugging my gwt app

[yves]

Hello All,

I need to debug my gwt app. The problem is that I need to debug it OFFLINE.
After a tour on the net, I didn't found an answer.

Thus here is the scenario.

My GWT version is 2.4.0

Debugging the code is ok.
Running in production offline is ok, using a cache manifest.

But I can't do both : debugging offline.

To avoid any config difference, I use exactly the same tomcat server 
deployment to run in production or in debug mode (thus with the debug 
option -noserver).
The cache manifest is built in runtime by a dedicated service whose 
response depends on the current permutation.

When online, the manifest is always requested in debug and in production 
mode (confirmed by tracing). (a subsidiary question is : why in production 
the manifest is called twice and in debug it is called once ?).

Then I stopped tomcat.
=> In production offline the gwt app is running correctly.
=> In debug offline, nothing is displayed : the browser has loaded the app 
html file from its cache (confirmed by displaying the page source code), 
but the browser remains empty, the gwt app is not running.

It seems that when offline, the google dev plugin doesn't communicate 
correctly with the IDE as it even doesn't realize when the development mode 
is stopped in the IDE (the black overlay with the message "Plugin failed to 
connect to Development Mode server at localhost:9997" is no displayed). May 
be the plugin is not started when offline ?

In order to help me test my app when offline, does anybody knows why the 
app is not running in debug offline mode and how to make it run ?

Thanks a lot !
Yves

Re: Web Component support/usage?

[Ed Bras]

Thanks for the update.
Are things like these kind of "news" items put some where in the future ?
Maybe "better" use of the gwt blog ?

Re: Offline debugging my gwt app

[Joseph Lust]

It is not clear what you're attempting here. By "Offline" I believe you 
mean when not using the "DevMode" debugging plugin. You can only debug with 
the debugger when running in debugging mode. You can however use source 
maps and set breakpoints in the browser (i.e. Chrome Dev Tools) if you like 
without using DevMode.

Beyond that, to run your GWT app while not in the DevMode plugin, you'll 
need to compile and deploy it to a server (i.e. Jetty, Tomcat, JBoss) and 
start it. If you try to run it *not* in DevMode, but with the codesvr 
parameter in the URL, it will fail as it thinks you're trying to use 
DevMode.


Hope that helps.

Sincerely,
Joseph

Re: Offline debugging my gwt app

[yves]

Thanks for your answer, but my question is about the HTML5 offline feature. 
Sorry if my post was not clear.

The problem is that I can't debug the GWT app while running it without a 
connection to the site server, thus "offline".

Yves

How is it that gwt-user is deployed? It's only needed at compile-time and 
must not be deployed (gwt-servlet should, if you use GWT-RPC)

Is hosted.html / devmode.js (depending on your linker) available offline? 
(i.e. included in the appcache manifest)
