Re: Redirect to place

[A. Stevko]

I suggest you put the logic for parsing the place token within the
Activity.start() and if it does not parse then use placeController.goTo() to
load the NewRecordPlace. That way the association between activity and place
is relatively constant and the validation of the token is determined by the
layer that has the best access to the data model.

callback. so is there any way that i can stop executing client side
execution until i get data from the server. any way to block
asynchronous behavior so that i can wait for the data from the
server
this is the exampleim using like.. and i dont want JVM to execute
further till recordSet is not populated..thanx for looking into
it..hope u will help me out

 Service.loadData(mProcedureName, request, new AsyncCallback() {

public void onFailure(Throwable ex) {
 
Logger.getLogger(DataServiceImpl.class.getName()).error("Load data
failed.", ex);
}

public void onSuccess(Data data) {

Redirect to place

[Juan Pablo Gardella]

Hi folks,

I have a problem with places. For example I have the URL  "
http://mysite/myapp#editrecordd:10"; and I want with this URLgo to place
EditRecordPlace (OK!), but if I have this URL  "
http://mysite/myapp#editrecordd:10asiuo"; (the id can't cast to a number) I
want to go to another place, for example newRecordPlace.

I can do that in this manner:

public Activity getActivity(Place place) {
...
if (place instanceof EditRecordPlace &&
((EditRecordPlace )place).getId()==null){
return appPlaceFactory.getNewRecordPlace().getActivity();
}
...
}

But the problem is that no refresh the URL, I want display in the URL *
newRecord* and start the activity. If I invoque the
placecontroller.goTo(appPlaceFactory.getNewRecordPlace()) don 't works.

Regards,
Juan

Re: Eample for MVP+EventBus+Presenter+Activity

[A. Stevko]

My experience with Roo was a bit overwhelming. The amount of code generated
and the instant complexity was a lot for me transitioning from 1.x to 2.x
style GWT programming. While the learning curve is hard and steep, building
an MVP++ app from the ground up forced me to learn the details from the
inside out.

I bookmarked a diagram posted on the gwt-contrib form that helped me
visualize the Activities + Places/History mechanism.
http://groups.google.com/group/google-web-toolkit-contributors/msg/7713e6c5d1bb5656


http://tbroyer.posterous.com/ is a must read for understanding how to use
the many parts of the frameworks.

If you go with starting out small, the first step beyond building the sample
application is to integrate Gin. Its essential to start early with DI
because it impacts everything and integrating while the project is small
saves a lot of rework.
I also suggest sticking with building out the Place - Activity - View
communication interfaces rather than customizing EventBus messages.
Marshaling custom events and handlers adds a lot of complexity.   The Place
Controller and Request Factory are wonderful abstractions on top of the
EventBus. After you've build a few CRUD panels by hand, you can really
appreciate the help given by the Editor and CellList/Table frameworks
although mastering them causes hair loss.

Null Version

[Pavel Byles]

I'm getting the following error when I'm using requestfactory with locators:


   The persisted entity with id 152 has a null version

I have a version column in my datastore and the following in my Entity:


   public Integer getVersion() {

  return this.version;

}


public void setVersion(Integer version) {

  this.version = version;

}

I also have this in my locator:

   @Override

public Object getVersion(Country domainObject) {

  return domainObject.getVersion();

}

If I return 1 all the time for getVersion, everything works fine.

I have looked at all the examples I could but there aren't many and tried to
figure this out for a while. Things look right but doesn't seem to work.

Any ideas?

GWT+GAE+Tomcat - java.lang.NullPointerException: No API environment is registered for this thread

[Anoop John]

Hi,

I have developed an application in two ways:

1) GWT+Mysql+Tomcat - Here the GWT compiler was compiled java code to
JS. In the server side the data stored inside the Mysql database. Here
i didn't used Google data store. It worked fine when i deployed in
tomcat server.

2) GWT+GAE+Tomcat - Here i used the Google Data Store instead of MySql
database. This application doesn't worked and crashed at server side.
The exception is occured at the code "List
list=(List) query.execute("username");" . The whole code is
given below.

   PersistenceManager
mngr=ServerUtils.getServerutils().getPMF().getPersistenceManager();
try{
String filter="username==filter";
Query query=mngr.newQuery(DB_Users.class);
query.setFilter(filter);
query.declareParameters("String filter");
List list=(List) 
query.execute(username);
if(list!=null&&list.size()>0){
return false;
}
else{
return true;
}
}
catch (Exception e) {
e.printStackTrace();
}
finally{mngr.close();}
return false;

The error is:

Re: Holy Cow! GWT Designer comes up quick in 2.4 beta?!?!

[Eric Clayberg]

As you noticed, we have been working on a lot of optimizations that
should result is a much better user experience. The first time you
access GWTD in a session, it still needs to warm up dev mode (which
takes most of the time...and is itself much faster now). Subsequent
editor opening operations should be much quicker and switching between
source and design mode should be extremely quick.

Debugging GWT in IntelliJ when GWT is running embedded in Grails

[Gambo]

Hi there,

is there a possibility to debug a GWT application even when its HTML
page is embedded in a gsp grails page?

I am using the gwt grails plugin but it would be much nicer if i can
run the intellij debug mode for gwt.

Thanks for your help

Re: problem with crawler

[Qiang Ma]

Hi,

I am scratching my head with the same issue. (Haven't decided what to do
yet.)

Just want to learn what you have done.
So your servlet will route regular URL (pretty one) to your GWT app, and the
escaped one to some static page? (Are you using HtmlUnit?)
I have a question on the "static page": can I change the title to be more
specific to the content (e.g. some search result)? But would that be
considered bad because user would not see it in the real application?

Wish you can figure it all out!

Re: RequestContext.fire() ignores server errors

[Thomas Broyer]

Request#fire(Receiver) is a shorthand for 
Request#to(Receiver)+RequestContext#fire().

With RequestContext#fire(Receiver), you'll generally have onSuccess called, 
whether the individual method calls have succeeded or not. onFailure will be 
called for "general failure" only (unable to parse request, load objects, or 
serialize them back and write the response; or a "transport failure"), 
because "overall", the "batch request" succeeded.

With Request#to(Receiver), the receiver is bound to a specific service 
method call: onSuccess means the specific method call succeeded, and 
onFailure means it failed (either this specific method call, or a "global 
failure").

onViolation, when called, is called on all Receivers (bound to a method 
call, or the "general" one), because validation is done before method calls 
(operations) are processed (just after objects have been "reconstructed")

In brief: this is not a bug.

I am not sure if you mean something like a collapsiblePanel.
Check out this link and see if it helps.

SplitPanel but with single click open/close

[joel]

Is there a widget for this already? Much like the GWT info pages? ie.
http://code.google.com/webtoolkit/doc/latest/DevGuideUiPanels.html#LayoutPanels

Notice the horizontalsplitpanel lets you click on it to open/close.
Does this exist as a GWT layout component already?

RequestContext.fire() ignores server errors

[Stefan]

Hi Folks,

It looks like RequestContext.fire() ignores server errors (at last  in
GWT 2.2) . Consider the following code:

  driver.edit(myFooEntity,
requestFactory.fooEntityRequestContext());
  .
  FooEntityRequestContext context = (FooEntityRequestContext)
driver.flush();
  Receiver receiver = new Receiver() {...};

(1)  context.persist().using(myFooEntity).fire(receiver); // good
(2)  context.fire(receiver); // bad

If one takes the (1) approach, all works just fine. However, if one
takes the (2) approach, then onFailure() will never be called.

The problem has already been discussed once :
http://groups.google.com/group/google-web-toolkit/browse_frm/thread/6612c8e4fda142a0?tvc=1&q=RequestContext+fire.
However, no definite answer has been posted.  Additionally, the
problem seem to be related to 
http://code.google.com/p/google-web-toolkit/issues/detail?id=5872
bug. However, the bug is closed and fixed in 2.2 and the above
described behavior exists in 2.2

It would be nice if someone well versed in the the GWT design
clarifies if this is a bug or a design behavior.

Thanks
Stefan

problem with crawler

[ale]

Hello everyone,
I'm trying to make my webapp gwt visible to crawlers, following the 
excellent guide 
http://code.google.com/intl/it-IT/web/ajaxcrawling/docs/getting-started.html
I have done all that is indicated (meta tag in the head, fragment with!, 
servlet filter) but I have this problem:
servlet in the queryString is always null, also with the simplest url.
The only way to have a queryString not null, is to invoke a specific servlet 
different from the default:
I explain with to sample (from my site):

URL that don't work:
http://www.youtrail.com/#!home   
I try 
http://www.youtrail.com/?_escaped_fragment_=home
but from log I see that queryString is null 
(and on the browser I land on 
http://www.youtrail.com/?_escaped_fragment_=home#!home)

what is wrong? Why in my filter I saw always queryString null?

Thanks a lot and sorry for my bad english
Alessandro

Re: which permutation which user.agent HTML5 manifest help!!!

[Evan Ruff]

Shawn,

I'm running into this exact same problem. I am generating the cache manifest 
using a servlet filter, but I cannot figure out which hash is the 
appropriate file.

Did you ever find a solution to this? Does anyone else have a solution to 
this issue?

Thanks!

Using a custom DateFormatProvider in GWT

[Panam]

Hi,

since the J2EE runtime seems to revert to some inappropriate standard
locale when using the actual locale "ta-IN", I've written a customized
DateFormatProvider and successfully deployed it to the application
server. It looks like this:

public class TamilNaduDateFormatProvider extends
java.text.spi.DateFormatProvider{

@Override
public DateFormat getTimeInstance(int style, Locale locale) {
return DateFormat.getTimeInstance(style, Locale.UK);
}

@Override
public DateFormat getDateInstance(int style, Locale locale) {
return DateFormat.getDateInstance(style, Locale.UK);
}

@Override
public DateFormat getDateTimeInstance(int dateStyle, int timeStyle,
Locale locale) {
return  DateFormat.getDateTimeInstance(dateStyle, timeStyle,
Locale.UK);
}

@Override
public Locale[] getAvailableLocales() {
return new Locale[]{new Locale("ta", "IN")};
}

}

It needs to be packed into a jar with some meta information and
deployed to the runtime's lib/ext directory.
Here is some background: 
http://download.oracle.com/javase/6/docs/technotes/guides/extensions/index.html
For server code, this works fine. However, the GWT-UI in my case still
uses that inappropriate default locale (even after doing a
recompilation using the extended (by the customized
DateFormatProvider) runtime.
So my question is: How does GWT determine the proper date formatting
for the locale sent from the browser and how could I plug-in into this
system to have "ta-IN" properly supported?
Apparently, the standard Java mechanism does not work, or am I wrong?
Is it because GWT uses the SDK rather than the runtime? I tried to
create the corresponding lib/ext Folder even in the SDK and put the
jar there but this also did not help...

Regards,
panam

Re: Wrapping element as Widget and adding click event

at the moment I have a situation like below in my .xml file and some

Is it possible using CellTable to replace code below (in the .xml not

Re: Installing GWT 2.2 in Eclipse

[David Chandler]

You can obtain prior versions of GWT from Maven Central or
http://code.google.com/p/google-web-toolkit/downloads/list. You can use the
Configure GWT SDKs feature in the GWT properties dialog for the project to
use a downloaded version of GWT instead of the GWT SDK 2.3 you installed
with the plugin.

For the plugin itself, prior versions are not available.

Re: Referenced Projects for GWT

[Ahmet Dakoglu]

Reference the external gwt project to your MainGwt project from build path,
and inherit it from your .gwt.xml file like 

*"com.external.project.AnotherGwtProject*" is the path of gwt.xml file of
external gwt project. To use my own gwt widgets in different projects , i
followed those steps.

Installing GWT 2.2 in Eclipse

[Rajesh Prabhu. R]

Hello All,

I need to install GWT 2.2 in Eclipse.

I tried to use the below URL but it is installing GWT 2.3
http://dl.google.com/eclipse/plugin/3.6

Is there a way to get GWT 2.2 and install?? Possibly a Zip file or an
installer??

How to uncheck header checkbox in Celltable when paging?

[atul]

How to uncheck header checkbox in Celltable when paging?
The header checkbox is used to select/unselect all the rows in
Celltable by a single click on it:
Like we see in gmail and yahoo mail

The problem is that after selecting the header checkbox in the current
page,
it remains selected after paging to next page

I am using SimplePager for paging the celltable data

If your app allows multiple sessions (e.g. tabs), then you should 
include a session ID in the cookies. It should not be necessary to 
maintain an instance count.

Re: dynamic proxy

[Michał Jabłoński]

I am going to create universal proxy to server object. I want to user
call method of class (any kind he creates) on client side which will
be calling the same method on server object and return value. Dynamic
proxy is exactly what I need.
So the only way is to call a class by name?

If it had been the case, the Request would have been declared as Request, but it's not, because you can have a 
Request>, or a Request or Request (or 
Request>), which obviously don't extend BaseProxy.

If you declared a Request where you erroneously imported java.sql.Date 
instead of java.util.Date, having "Invalid Request parameterization: 
java.sql.Date must extend BaseProxy" would be inaccurate and probably more 
confusing than without the "must extend".

Re: Problems using RequestFactory

[Ryan McFall]

It was through looking through the GWT source that I realized the
source of my error, so that's definitely a good pointer.

It would have helped me if the error message was:
Invalid request parameterization:
edu.hope.cs.surveys.dao.pojo.Tag must extend EntityProxy

I think that would be a valid error message, right?  Adding "must
extend EntityProxy" would seem to make it quite clear what had gone
wrong.

Eclipse Plugin interaction with RequestFactory

[Ryan McFall]

In moving from Gilead to RequestFactory, one of the things I've found
that I don't like is that there's no way for the compiler to make sure
that I haven't screwed up when I claim that a particular EntityProxy
is a proxy for a particular domain object (perhaps I've mistyped the
name of a method in the EntityProxy declaration, for example).  This
also comes into play when I annotate the RequestContext interface with
a Service annotation - I don't find out until runtime that I haven't
implemented a needed method.

I think I understand why this can't be done by the compiler, but I can
easily envision how it could be done by the Eclipse plugin.  The
plugin already does this for the synchronous/asynchronous versions of
GWT-RPC interfaces, for example.

I'm pretty sure I could write my own validator, but I'm curious if
there are plans in place to add functionality like this to the Eclipse
plugin.

Thanks!

Alternatively use

.color-icon { 
  height: 16px; 
  width: 23px; 
  background-image: none *!important*; 
  background-color: #77; 
}

Re: How to set background color for button?

[Piro]

Have you tried something like Firebug to see applied css in browser?
It helped me when i was making some css stuff, since i am just css
beginner.

Re: dynamic proxy

[Paul Robinson]

No. It's not clear exactly what you're trying to achieve, so it's hard to 
suggest an alternative. You have almost no reflection available in GWT - almost 
the only thing you can do is to ask a class for its name. So passing an 
interface as a parameter is not generally useful.

SelectionCell and celltable : each object in the cellTable may have it's own menu list

[Celinio]

Hi,
this question has already been asked but nobody answered.

http://groups.google.com/group/google-web-toolkit/msg/48a4109232fa2f35

Here is a snippet from the showcase sample :
http://gwt.google.com/samples/Showcase/Showcase.html#!CwCellTable

final Category[] categories = ContactDatabase.get().queryCategories();
List categoryNames = new ArrayList();
for (Category category : categories) {
  categoryNames.add(category.getDisplayName());
}
SelectionCell categoryCell = new SelectionCell(categoryNames);
Column categoryColumn = new Column<
ContactInfo, String>(categoryCell) {
  @Override
  public String getValue(ContactInfo object) {
return object.getCategory().getDisplayName();
  }
};
cellTable.addColumn(categoryColumn,
constants.cwCellTableColumnCategory());

I am facing the same problem :
I am also currently working on a project that requires that each  object in
the cellTable may have it's own menu list.  Can anyone
provide any clues as to how I would go about modifying the code so that each
object/row would have it's own SelectionCell?

Thanks for helping.

Re: GWT and Maven

[pansen]

Hm, not exactly.

But I would recommend to run your mvn command with ``-X`` and grep for
" Configuring " like::

 mvn clean compile package -X | grep ' Configuring ' -A 30

you can see all config options here and should be able to fit them to
your needs (inside the  section of ``gwt-maven-
plugin``)::

[DEBUG] Configuring mojo 'org.apache.maven.plugins:maven-war-
plugin:2.1-beta-1:war' with basic configurator -->
...
[DEBUG]   (s) outputDirectory = /Users/abalke/project/xx/vz-gwt-
main/target
...
[DEBUG]   (s) warName = vz-gwt-main-0.1.11-SNAPSHOT
[DEBUG]   (s) warSourceDirectory = /Users/abalke/project/xx/vz-gwt-
main/src/main/webapp
[DEBUG]   (s) webappDirectory = /Users/abalke/project/xx/vz-gwt-
main/target/vz-gwt-main-0.1.11-SNAPSHOT
...

This should work locally the same as on your hudson as it seems not
like you're using any Maven Profiles yet.

Hope this helps a bit.

Scrollable GWT Tree

[Natalie.Lawrey]

Hi
Is in GWT any way to wrap standard Tree in scroll panel without hard-
coding size of the tree?

I mean
ScrollPanel scroll = new ScrollPanel(myTree);
scroll.setSize("100%", "190px");

works perfectly - but desirable result is to occupy by the Tree as
much space as it is only possible (parent container has % size, so on
large screen it's huge). I don't wanna fixed size as above Any
clues or hints?


Regards!
Natalie

Re: GWT meets Adobe Flex: gwt4air 2.1 is here !

[leandro borbosa]

This is a free time project ? ?
Really impressive stuff.

"Hopefully i did a good job at that."
I  ve played around with the library i must say you did more then a good job
at that.
I still cant believe i m writing a Flex application.

I just wonder what makes you start this project. I mean Flex is not a small
framework. Exporting it to GWT must have been some hard work.

Re: when i am using this code it gives error

[vinayak kulkarni]

Before making the jar containing ContactEntry class, put these module - 
ui.xml files and then export as jar with source code.

Inheriting is same as i explained above. You need to inherit all the modules 
which have the classes used in the client side.
It is only used by GWT compiler while converting into javascript.

Re: How to add checkbox in header.

[atul]

Hello,

Thanks for showing how to add an checkbox in the celltable header.

I have another question in this regard.
I am showing this celltable data with checkbox header as above 
as first column and 
other columns as Name, Address, etc.
Also I am using SimplePager to show the data in celltable 
in paginated format with pagesize 5.

Question:
The first 5 records are shown in first page and 
when the uses clicks the 
checkbox header cell all the first 5 records in the celltable are selected 
alongwith the checkbox header cell itself.

On paging to next page by clicking the next page image(or icon) on the 
SimplePager, the next 5 records from the celltable are shown  
but the checkbox header cell remains selected (true) 
as I had clicked it in the first page.

I need the checkbox header as unchecked again (false) 
when the user clicks on the 
next page and new records are shown.

SimplePager does on raise any event 
on clickcing the next page image(or icon).

Please Help

Thanks and Regards,
atul gaikwad

GWT fails in recognising common module CSS file referred in common module - ui.xml file.

[vinayak kulkarni]

Hello,
I have a common module, module1.gwt.xml . It is not an entry point class. It 
is just inherited from main module.

In common module, i have a widget and its respective ui.xml file which i 
want to reuse in other module.

*package - common.client.view.*

*MyWidget.ui.xml: *
http://dl.google.com/gwt/DTD/xhtml.ent";>


 

   



*MyWidget:*
public class MyWidget extends Composite implements 
LeafValueEditor>
{

  private static MyWidgetUiBinder uiBinder = GWT.create(MyWidgetUiBinder 
.class);

  @UiTemplate("MyWidget.ui.xml")
  interface MyWidgetUiBinder extends UiBinder
  {
  }

.
}
 

Now i have another module, which is the application module and is an 
EntryPoint class.
I want to reuse the common ui.xml file in the application module.
I reused it in the following way with the fully qualified name for the 
uitemplate annotation as below:

*package: application.client.view*

public class MyApplicationWidget extends Composite implements 
LeafValueEditor>
{

  private static MyApplicationWidgetUiBinder uiBinder = 
GWT.create(MyApplicationWidget 
.class);

  @UiTemplate("*common.client.view*.*MyWidget.ui.xml*") 
  interface MyApplicationWidgetUiBinder extends UiBinder
  {
  }

...
}

But, when i compile this code using GWT compiler, it gives the compilation 
error saying it cannot find *Common.css*:
Below is the snippet:
Invoking generator com.google.gwt.uibinder.rebind.UiBinderGenerator
ERROR] Unable to find resource: application/client/view/FACommon.css
   validating {myStyle.sectionContent}
  [ERROR] Can't interpret CSS
  [ERROR] Could not find no-arg method named sectionContent 
in type com.google.gwt.resources.client.CssResource.

It is trying to find the CSS file in the same path where the view(widget) 
is.

Could anybody help if there is anyway where in we can override this 
behaviour of GWT and keep the CSS file from wherever we want.

Any help is appreciated.
