RequestFactory Chained Persistence

[Patrick Cailly]

I have a Patronyme Entity with a chained Entity ( Patronyme root; ) 
the server side is working ( I've got a PatronymeDTO with RPC working )
I can get a PatronymeProxy with findPatronyme on the client side

but the getRoot raises an exception

I must be missing something
it seems that there is no data for root

I tried to implement it differently ( from expends example )
in the entity
public Patronyme getRoot () { return Patronyme.FindPatronyme( 
root_id ); }
it raises a different exception

What's wrong ?
Please ?

Import GWT prj

[Marco Gadaleta]

Hello everyone,
I'm trying to create a "project of Utils" for other GWT Project.
In this "Utils" I can put some code so that  does not duplicate it.

There is a way to do this if considering that in Util Project could be GWT
ui code (layoutpanel, button, etc..)?


Thx

Re: ProxyAutoBean server-side cache

Opened an issue:

Will send a patch of the "fixed" WeakMapping soon, after I test it a bit. A

test it a bit to make sure it doesn't cause any issue!

DialogBox Visibility

[Patrick Cailly]

How can you be sure that a DialogBox and its included widgets will be visible 
over Any Widget ?

When I drag my DialogBox above a SWF widget , only the handle of the DialogBox 
is visible.

the same with an OpenLayer Map

is there a way to control the "level" or "priority" of widgets ?

Thank 

Patrick

Re: ProxyAutoBean server-side cache

[Patrick Cailly]

Thanks for that reply

If the problem is caused by a circular reference ,
does it mean that the problem disapear whe the reference is a reference to 
another Entity
let's say , I could have Root entity an a Patronyme Entity and Patronyme 
chained to Root to solve the problem
( or the fix should available soon ? )

I thought that the *.nocache.js was being generated by the code
server, or
when I explicitly compile the code. Does that mean that if I am using
tomcat
to host the GWT page I have to run the compile manually every time
I try to run the application.

It is being generated by DevMode when you launch it (which explains why the 
-war argument is mandatory even with -noserver), unless it already exists 
(unless it's older than the gwt-dev.jar, maybe, can't remember the details 
for sure).
...and by Compiler, of course, unconditionally.
When generated by DevMode, it only contains the code that's necessary to 
launch DevMode.
In any case, it contains nothing related to your Java code, everything comes 
from the *.gwt.xml files; with the exception of the permutation IDs (names 
of the *.cache.html/js files when you compile your app).

Fortunately not!

If you can point DevMode's -war to the folder where Tomcat reads the files 
(exploded web app), then you don't need to compile your app, not even once.
Otherwise, you'll have to compile the app once (or launch DevMode once and 
then deploy the generated *.nocache.js file)

Really, compile once in -style PRETTY to have a look at what it looks like 
and how it works.

gwt-user.jar think as a util. You must package the jar with the sources and

Is this a bad approach?

Re: One GWT WebApp but more than one WAR files

[deejay]

Sorry i think the question was unclear. Of course, we need a shared
repository.

The main question was, how to develop a GWT application which is
splitted in MULTIPLE war files which could be deployed separately in
the webapp server...

No estoy seguro de como bajaste el plugin del que hablas (y qué plugin

Re: One GWT WebApp but more than one WAR files

[Juan Pablo Gardella]

I think, is your wars are related, you can develop a jar with commons
funtionality and have multiples war that use it.
Then develop each war independent.

Sorry my english :)

Re: Who processes the gwt.codesvr parameter a browser plugin or java script on the hosted page

[Chris Conroy]

It's used by the bootstrap to know to load the plugin, and then it's used by
the plugin to connect to the code server.

TabLayoutPanel

[Marco Gadaleta]

Hello,
I'm using DecoratorTabPanel inside my gwt project but
the compiler say me that DecoratorTabPanel was deprecated and recommend to
me to use
TabLayoutPanel.
But a TabLayoutPanel doesn't work  inside a RootPanel that is the component
that i must use.

Some suggestion?

Is there a way to set DecoratorTabPanel to 100% in width and height?

The exception:

Mean that you must recompile (I don't know why :( ), recompile and test

Sort order is lost in CellTable

[jgranie]

Hi,
I'm using a CellTable (GWT 2.2) with some sortable column. When the
user clics on sortable column header, the CellTable is sorted
correctly, but if there's an update on some data, the updated row is
moved to the end of the table.
By "update" I mean refreshing data from server. To refresh data at
index I'm using getDataProvider().getList().set(index, data).
Is there something else to do ?

Thanks

How can you get a Widget or Canvas in the DecoratedStackPanel header?

[Jacob]

Hi,

I'm interested in getting a Widget in the header of a
DecoratedStackPanel.  My goal is to put a horizontal Slider which has
details about the changes show in the lower Widget.

I realize it may not be possible, but the ability to treat the header
as HTML suggests it may be capable of other things.

Jacob

Interface problem between GWT and C using JNI

[ganesh]

Hi,

I am planning to change the look and feel of the existing project.
My current project has backend code in C, and JNI layer to interact
with GUI(JAVA). Upon user actions in GUI, I transfer the information
to backend using JNI calls. Recently I came across the GWT and
impressed with it, thought of using it for current GUI, but am stuck
in interfacing GWT JAVA code(server) making JNI call to C code.

Just to test the GWT and JNI,
i) I added a sample GWT web application(example provided by Google in
GWT documentation) code to eclipse, where server and client code is in
Java. It is working fine after compiling in eclipse.

Later I added 'HelloWorld.c' file which just prints the 'Hello world'
to standard output stream, and a Hello.java file at server side, which
loads the native object file to Test.java file using inbuilt load
library function call.
Then I made a 'Test' class call in original GWT server JAVA file.

NOTE: I've linked the jna.jar file to eclipse for this project as
external jar file(as per GWT documentation), and placed the native
library file of C along with the Original GWT server class file.

Now when I try to compile the above code in eclipse, eclipse shows up
the message stating :
---
Starting Jetty on port 
  [WARN] Exception while dispatching incoming RPC call
com.google.gwt.user.server.rpc.UnexpectedException: Service method
'public abstract java.lang.String
com.mycompany.mywebapp.client.GreetingService.greetServer(java.lang.String)
throws java.lang.IllegalArgumentException' threw an unexpected
exception: java.lang.UnsatisfiedLinkError:
com.mycompany.mywebapp.server.GreetingServiceImpl.sayHi(Ljava/lang/
String;)V
---
Appreciate your help.

Thank you,
Ganny

GWT: com.google.gwt.core.client.JavaScriptException. only using Internet Explorer

[Sergio García]

Hi,

Before explain my problem, I have to say that my GWT version is 2.2.0
and the error only has place when I use Internet Explorer (in this
case IE 8).

I have a little GWT project which contains a button that throws the
next method:

private void expotarExpediente(VistaExpediente vista) {
final String templateURL = GWT.getHostPageBaseURL() + 
"exportar?id="
+ vista.getId();
Window.open(
templateURL,
"Resultado de expotar el expediente: "
+ vista.getNumeroExpediente(), 
"");
}

This method creates a template URL to call to a classic HTTPServlet
("exportar") which generates a Zip File to download by users.
The sentence  Window.open(...) open a window in the browser that
allows download the file.

This works correctly in all browsers except Internet Explorer.
The thrown exception is the next:

The thrown exception is the next

it.

Help: How to refresh Button Text?

[Rodrigo JS]

Hi All,

I am new to GWT and was trying to create an horizontal panel with 5
Buttons on it. So far, so good.

Point is that when I implemented the method that would define what to
be written in each Button it did not work.

Can anyone helpe me?

Thanks,
Rodrigo

 public void onModuleLoad() {

  hPanel.setSpacing(10);

  // Add some content to the panel
  hPanel.add(Stop1Button);
  Stop1Button.addStyleName("B1");
  hPanel.add(Stop2Button);
  Stop2Button.addStyleName("B2");
  hPanel.add(Stop3Button);
  Stop3Button.addStyleName("B3");
  hPanel.add(Stop4Button);
  Stop4Button.addStyleName("B2");
  hPanel.add(Stop5Button);
  Stop5Button.addStyleName("B1");

  // Associate the Main panel - hPanel - with the HTML host page.
  RootPanel.get("stopList").add(hPanel);

  // Setup timer to refresh list periodically.
  Timer refreshTimer = new Timer() {
@Override
public void run() {
  refreshStopList();
}
  };
  refreshTimer.scheduleRepeating(REFRESH_INTERVAL);
  }

  private void refreshStopList() {

  // For testing purpose, generate a second screen with different
text then the first one

  // hPanel is cleared
  hPanel.clear();

  // I could do it altogether , but am testing if it is working step
by step
  // Text generated in tester is associated with a variable
  textButton1 = "Test 1";
  // Text received is attributed to a button
  Stop1Button.setText(textButton1);

  // Button is added to the Screen.
  hPanel.add(Stop1Button);

  // hPanel is associated with the screen
  RootPanel.get("stopList").add(hPanel);

  }

IE v Firefox

[Greg Dougherty]

So, I have a quirks mode web app using GWT 2.1.2.  It runs just fine
under Firefox, Sea Monkey (Mozilla derivative), and even Safari (on my
iPhone).  On IE, however, it pops up the password dialog box, accepts
a user id and password, then gives a completely blank screen.  On
errors on the server side.

How do I go about debugging this sort of problem?

TIA,

Greg

Re: gwt + spring + maven

[mariyan nenchev]

I did recompile, but with no effect. I use gwt 2.2 and after updating the
libraries (gin 1.5 and gwt-dispatch) it worked.

Is treated as spring backing bean?

Our existing project structure is:
-jsf
-backing bean
-service
-dao

Thanks for the info.
It seems you might get partially updated objects to the server then?
If it is possible for the user to modify the objects in the client
while the RPC-
code is serializing, I mean.

IOW. if I can run into trouble, so can you.

Or maybe there is no problem? Would be nice to know for sure ...

You get there automatically when your browser reaches the development mode

No App Identifier is available

[Bob]

Trying to follow the instructions at 
http://code.google.com/webtoolkit/usingeclipse.html the last part, deploy to 
google app engine.

I am an absolute newbe to GWT.

Everything has worked fine up to here.  But I cannot get an application 
identifier.  Regardless of what i put in at 
https://appengine.google.com/start/createapp.do (got there by clicking on 
App Engine Administrative Console link in instructions above) in the 
Application Identifier field, it comes back and says that identifier is not 
available.  I have tried very long random strings of numbers, everything.  

So I am stuck.  Any ideas?

Thanks,
Bob

A few ideas:

   - Install firebug-lite
   - Use development mode to step through your code after the login process
   completes.
   - Are you using Gin? If so, create a mock login authentication module to
   save yourself that step
   - Which version of IE? Six? Good luck.
   - JSNI code? I'd start there.
   - Custom attribute settings? element.setAttribute... Review those.
   - GWT.log or logger is your friend

Re: Need some help on Editors

[Potate]

hi Thomas

thank you for the reply. After reading your email and the referenced
examples, it makes much more sense now.
I have one more question poped out.
How does the editor framework work with inheritance?
say I have

interface Base {
String getBaseProperty() }

interface Child extends Base {
String getChildProperty() }

currently, without the editor framework, I have one view that displays
both Base and Child. I do a check with instanceof with the object to
be displayed and toggle visibilities of widgets accordingly. How might
similar functionality be implemented with the editor framework? I
poked around but had no luck.
class View implements Editor did not work because the child
property sub editor was complaining about no child property getter in
Base
class View implements Editor could work, but I have to wrap
Base as a Child, which somewhat breaks the meaning of inheritance
class ChildView extends View implements Editor doesn't work
because java does not allow implementing the same interface twice

thanks

Re: IE v Firefox

[Greg Dougherty]

> One more thing - why are you using quirks mode?
Because I'm utterly uninterested in trying to figure out what the
dimensions of my panels should be, so I don't ever use any of the
*LayoutPanels.

Every web app I've ever written has had its size dependent upon the
user's input.  I can write a lot of code to try to figure out how big
things should be, and then resize everything appropriately, or I can
use Quirks mode and have the Panels do that for me, while I focus on
the issues that are specific to my app.

Which do you think is a better use of my time?

I've never seen an explanation of why the *LayoutPanels are the way
they are (just the bald statement "can't give you Swing like sizing in
Standards mode"), but even if it's a really good reason, it wouldn't
really matter.  Because as long as I can simply focus my efforts on
the problems important to me, that's what I'm going to do.

Well, I've taken a look at it, and maybe after I figure out what a
"bookmarklet" is I might feel more comfortable using it.  But thanks
for the pointer.

Yeah, 30 seconds after I posted this it occurred to me that I COULD
test this under development mode, not just as a deployed app. :-(

What's worse, is that I found the problem, and it's one I'd previously
discovered on Dec 8: IE 7 throws an exception when you try to add
something to a HorizontalPanel whose horizontal alignment is set to
ALIGN_JUSTIFY.

Ah, well, at least this time I submitted a bug report.

Thanks Jeff,

Re: One GWT WebApp but more than one WAR files

[Greg Dougherty]

The question is, why do you want to do it that way?

You can develop separate modules, and include all those modules in one
project / war file.  You can build multiple libraries, and include
them in multiple projects / war files.

What are you doing that requires you to have multiple war files?

GWT 2.2 and FocusWidget

[bconoly]

Hey All,
   We recently upgraded to gwt 2.2 and one of our widgets that extends
FocusWidget is no longer firing the onfocus and onblur events.  Does
anyone know why or how that could happen?  If so, do you know a fix
for it?
Thanks

Any GWT widget should work in Standards mode. It may be interesting to see
if the problem disappears in Standards mode. Also, there's the
X-UA-Compatibility header for IE. Are you using that header?

I don't remember the linkage between bookmarklet and the install. ISTR that
the bookmarklet gives you on-demand access to FBL. But I could be wrong.
When I'm using IE, it's always for testing, so FBL is always running.

UIBinder doesn't consider new line as a space in IE?

[Philippe Beaudoin]

I've remarked that if you have a new line between two elements (or widgets?) 
within a HTMLWidget in a UIBinder file, then Chrome and Firefox displays a 
space between them whereas Internet Explorer doesn't. This can cause some 
headaches when a seemingly stylistic reformatting of a .ui.xml file has 
visual impact on only some browsers.

Is this a known bug?

Re: UIBinder doesn't consider new line as a space in IE?

[Philippe Beaudoin]

In case anybody is interested, the "fix" (or, "convention") we came up with 
was to put the two elements on the same line separated by an   just so 
that anybody refactoring the file is aware that the line should not be split 
in two.

Clickable image in a CellTable & changing cell types

[Yaakov]

Hi,

Is there an example out there I can look at for the following 2 cases:

1) A clickable image cell. On click of that image, I want to execute
some functionality.

2) A textcell, when clicked becomes a drop-down (i.e., selection)
cell.

How do I accomplish those 2 tasks within the CellTable?

-Yaakov.

HTML widget takes too long to render

[azuniga]

I have a gwt webapp that makes an rpc to the server, the server
generates a report, then the report returns a string, which is just
the html contents of the report, which contains a large amount of
html. After timing the rpc and how long it takes for the html to be
returned and a new html widget to be created and added to the panel,
its about 1 minute. 27 seconds is spent running the report generation
code. However, it takes really long for the html to render or to
appear on the firefox page, about 2 minutes and 40 seconds and I am
wondering why if all the code is completed in 58 seconds, why does it
take so long for the html to display? It feels like it freezes up the
computer for that time in between the 58 seconds and the 2 minutes and
40 seconds. Anyone have any insight? Also, any insights into how I can
make my code more efficient or faster? Any links or info is greatly
appreciated.

Designer Problem : « uibinder template should be in client package »

[HommeDeJava]

Greetings folks,

I've tried to add UIBinder Composite widget in a project which was
initiated without UiBinder using GWT plugin.
So, when I tried to open xxx.ui.xml into the designer view, I've got
the error « uibinder template should be in client package »
You are attempting to use UiBinder for .../xxx.ui.xml however it is
not in Java package.

Did someone get this problem or have any idea?

Thanks

Claude

Hi,

Yes indeed I've put the myUIBinderComposite.ui.xml and
myUIBinderComposite.java files into the client package

It's when I try to use the GWT Designer opening the
myUIBinderComposite.ui.xml file using the Design Tab that I've got the
error.

Anyway, thanks for your help.

Re: Clickable image in a CellTable & changing cell types

[Alex Nederlof]

Hi,

I maybe have a solution for the first problem: You can set an image in a
button. Another option is to just adjust the CSS of a specific button to
have that image as a background.

Best,

Ale

Re: One GWT WebApp but more than one WAR files

[Alex Nederlof]

as far as I know, can only have one war file per application.

If you want to split up your application into modules (which is an excellent
idea if you're building a big application) I suggest you use Maven. There's
an excelent guide here about building a war from multiple jar modules:
sonatype.com/books/mvnex-book/reference/public-book.html

Good luck,

Alex

AutoBean and Generic types (Server-side)

[d95sld95]

I am trying to solve an issue with AutoBean and generics on the server
side.

When I run the test below I get the following output:

{"name":"SomeName","version":"1"}

But I did except to get the following:

{"name":"SomeName","id":"10","version":"1"}

For some reason the AutoBean framework does not detect the generics
Dto that is used for the id (K id). The id property is resolved to
a java.lang.Object in the
com.google.gwt.autobean.server.ProxyAutoBean class static method
calculateData(Class beanType).

I had hoped it would be more advanced and used something like this:
http://stackoverflow.com/questions/182872/how-to-test-whether-method-return-type-matches-liststring

Is the limitation by design or is it a bug. Is it maybe limited
because of client-side constraints and java support?


##

import org.junit.Test;

import com.google.gwt.autobean.server.AutoBeanFactoryMagic;
import com.google.gwt.autobean.shared.AutoBean;
import com.google.gwt.autobean.shared.AutoBeanCodex;
import com.google.gwt.autobean.shared.AutoBeanFactory;
import com.google.gwt.autobean.shared.AutoBeanUtils;

public class AutoBeanTest {

public interface Dto {
public K getId();

public Long getVersion();

public void setId(K id);

public void setVersion(Long version);
}

public interface MyDto extends Dto {
public String getName();

public void setName(String name);
}

interface MyFactory extends AutoBeanFactory {
AutoBean myDto();
}

@Test
public void test() {

AutoBeanFactoryMagic.create(MyFactory.class);

Re: RPC Problem with HashMap containing ArrayList Value

[Ben Imp]

The more generic your remote interface, the more code the GWT compiler
generates to try and handle all the possible values you may pass
through it.

Having a method that can take something of type Serializable would, I
believe, make the GWT compiler generate code for all possible types,
since you can't get any more generic than that.

Howto: Optimising RPC

[George Georgovassilis]

Hello all,

I've been spending some time with reducing RPC payload size and
optimising the request pattern and thought I'd share my pain and
wisdom with you :-)

You can read the full story here [1], the main points I am discussing
are:

- rewriting RPC to use GET over POST for reduced network packet count
- type name elision (and pitfalls)
- packing variables (and when not to)
- using higher gzip compression ratios
- batching requests

Please feel to post any comments
G.

Re: Howto: Optimising RPC

[Gal Dolber]

Nice post, thanks.
I am having a problem code-splitting my rpc classes and dependencies when
using the command pattern.
Even if I only load the login screen, if it uses any command rpc it forces
my apps to load all of them. I am testing some solutions at the moment, any
thoughts on that?

Re: Import GWT prj

[brucko]

I have a separate Eclipse "Utils" project, without importing jars for
client side code.

You will need to create a separate *.gwt.xml file in your utils
project and inherit this in the gwt.xml file of projects that use your
utils. This allows GWT to find the source and compile it in.

 Make your utils project a required project on the build path.

Server side code for  me is a bit of an issue. Some one else may have
a better solution. At this stage I am restricted to making a jar of
the server side code and including it in the war directory. Although,
as I am using AppEngine, I suspect I may be able to change my
appengine-web-xml file to include this code when deploying - not sure,
haven't tried yet.

Hope this helps,

Geoff

Re: RPC Problem with HashMap containing ArrayList Value

[ciosbel]

Not necessarily a problem, but the serialization file is bigger and 
compilation can take a while longer.
When i faced that problem i also see plenty of warnings, but maybe recent 
releases are less verbose.

I got to use an interface that extends Serializable, and then mark my DTOs 
used with generics with that.

Hope that helps.

Re: When is an object passed over RPC safe to modify?

[Craig Mitchell]

I won't be losing any sleep over it.  Our data object structure is
pretty robust, so it would be highly unlikely that it would be able to
become invalid.  Also, I'd be surprised if the RPC serialization
occurred in anything but the current JS thread of execution.  So I'd
be a stunned mullet if we ran into trouble.

Having said that, I totally agree, it would be nice to know more about
how the serialization works.

Re: Howto: Optimising RPC

[George Georgovassilis]

Hello Gal,

Sorry, I've had so far no experience with code splitting, my 
applications are all monolithic beasts. I guess the real bloat is not 
the DTOs but the marshalling code generated for RPC, right?


I can think of a possible solution (haven't tested this) but it's ugly: 
assuming that my DTOs live in a defined hierarchy, lets take two as an 
example:


my.package.dto.a.*
my.package.dto.b.*

they can be reflected with a set of corresponding Commands:

my.package.commands.CommandA
my.package.commands.CommandB

where CommandA references only classes from my.package.dto.a and 
CommandB references only classes from my.package.dto.b. I realise that 
even this is a long shot because such a distinction might not always be 
feasible.


To make it worse, I'll probably need multiple service interfaces:

interface MyBatchServiceA{

ResultA process(List commands);

}

etc

If I can think of something better I'll post back
