Re: @FunctionalInterface VS @JsFunction

[Jan Blok]

Yeah sure, there are many workarounds...which leads to bloat as shown.
Then my request would be to by default have Runnable and Callable in gwt 
java emulation to be attributed by default with interop.JsFunction :-)

@FunctionalInterface VS @JsFunction

[Jan Blok]

Hi,

Would it be possible for GWTc to handle java.lang.FunctionalInterface as if 
it was jsinterop.annotations.JsFunction ?
The reason for asking is, I have this java code:

public void transaction(Runnable runnable) {
startTransaction();
try {
runnable.run();
}
finally {
endTransaction();
}
}

when I expose this method via jsinterop I get a warning "not usable from 
javascript"

I intent to use it from JS/TS as: myJavaLib.transaction(() => 
doSomethingInTransaction(...));

but this is not possible unless I supersource java.lang.Runnable and 
add @JsFunction 

It seems to me that @FunctionalInterface and @JsFunction are very similar 
already...

Regards Jan

Set css from GWT (dynamically) to element with multiple styles associated.

[Jan Zet]

I have an instance of TabLayoutPanel where number of tabs would be set 
dynamically. Therefore to align tabs to fill whole width of the screen I 
need to

1) Override gwt-TabTayoutPanel default value width 16384px with auto 
!important (done);

2) Set width of gwt-TabTayoutPanel*Tab* to proper percentage value (e.g. 2 
tabs = 50%. 3 tabs = 33%, 4 tabs = 25% and so on). I have a simple function 
for that which goes like this (simplified):

Math.floor(getWidgetCount()/100 + "%");

(done)

3) Now here goes my question: how can i set the width of gwt-TabTayoutPanel
*Tab* from Java? I bolded *Tabs* because when i use this.getStyleName(); i 
got in return gwt-TabLayoutPanel not gwt-TabLayoutPanel*Tab* .

In sum, I can divide my question in two:

-how to access TabLayoutPanel*Tab* css class from GWT?;

-how to set said class width with my dynamically generated percentage 
number?;

My additional thought: Is GSS can do this?

Running MobileWebApp from GWT_2.7.0/samples

[Jan Zet]

I tried running in SuperDevMode a MobileWebApp placed in Samples folder of 
GWT 2.7.0 package. I import it via Eclipse Maven plug-in, POM file is 
executed properly. Then I set Annotation Processing to Enable... and 
Automaticly. Finally, according to README-MAVEn.txt i execute Maven > 
Update project in project Properties. 
According to Readme file,at this point I should see a Run in Development 
mode option, but the thing is,i don't. So in project properties i enable 
use WebTollkit,GAE and set WAR directory to src/main/webapp. 

This gives me Eclipse error: 
Description Resource Path Location Type
The App Engine SDK 
'/home/user/.m2/repository/com/google/appengine/appengine-api-1.0-sdk/1.7.1/appengine-api-1.0-sdk-1.7.1.jar'

is not a directory) MobileWebApp Unknown Google App Engine Problem
Changing AppEngine to default doesn't fix it. 
Is there any way to run this app in SuperDevMode within Eclipse?

Re: GWT compiler doesn't create symbol maps files

[Jan Swaelens]

Hello,

Just wanted to notify everybody that the com.google.gwt.junit.JUnit 
inheritance is also included when you use the default errai module for 
example. We had to get rid of it by using our own module definition for 
errai excluding that entry.

Is Elemental safe to use cross-browser for event capturing?

[Jan]

Hello,

We'd like to use the Elemental library for event capturing. Something as 
simple as:

import static elemental.client.Browser.getDocument;

import elemental.events.Event;import elemental.events.EventListener;


   ...

EventListener listener = new EventListener() {  @Override  public 
void handleEvent(Event event) {...  }};
getDocument().addEventListener(Event.SUBMIT, listener, true);

Given Elemental's "close to the metal" approach and disclaimers about not being 
entirely cross-browser, is this a good idea? Or should we look at other things 
to avoid subtle bugs?

Many thanks!
Jan

Re: SeedTable is taking 6% of my applications memory

[Jan Thewes]

Ok I'm not sure if my "seedTable" guess was correct.
When looking at my window object I see the seedTable property. But what you 
can see in my original attached screenshot is not my seedTable.
Can anyone help me and tell me what it is?
It's a real large bunch of Strings which take 3MB of memory. That needs to 
be changed.

Request factory performance much worse than RPC

[Jan]

Resently I noticed some performance issues with my request factory 
application. I did some research and some debugging, but could not find any 
flaws in my application.

Then I created a simple test application to compare the performance of GWT 
and request factory to be sure I have a very simple application and no 
other components that could have an influence on the performance. And this 
test application shows same result: Data retrieval via request factory 
seems to much slower than RPC. The retrieval of 100 very simple objects 
takes with RPC ~200ms, with request factory ~700ms (Locally the difference 
is even much bigger).

I uploaded the code to github: 
https://github.com/jan10101/requstFactoryVSRPC

And deployed the application to app engine so it can be testet: 
http://requestfactorytest.appspot.com/

I also experimented with several approaches to increase the performance 
like overriding "ServiceLayerDecorator.isLive()" but could not archieve 
ansignificant improvement.

Is the performance of request factory a known issue? Am I the first one 
noticing this? Is there a way to improve the performance? Or du I just need 
to use RPC to get the best performance?

Re: XSRF protection using GWT example guide broken for Glassfish/ Jetty using JSESSIONID

GWT team appears to be vry reponsive... :\

I have the same problem and still can't find any solution...

Does anyone know how to fix it? maybe I should be setting all cookies with

the path is what I'm considering changing. 

What do you guys think?

Re: Compile Error after switching to 2.6 in first compile run

[Jan Thewes]

I understand your points BUT one thing. If I compile my modules alone I 
don't get any compile error. So compiling every single module works. It has 
to do something with the order and caches. I just can't nail it down.
We're running a real real big GWT application here.
I'm close to go back to 2.5.1 because the compiles fail too often but not 
always...

Re: Compile Error after switching to 2.6 in first compile run

[Jan Thewes]

Well, the order has to do something with the failing compile. But this is 
new with GWT 2.6. Before our compilation always worked. And we don't have 
changed our code since the change to 2.6. 
Still need ideas what this can be. In my opinion this is a GWT internal bug.

Re: Compile Error after switching to 2.6 in first compile run

[Jan Thewes]

Ok any further information.
We're trying to compile 5 modules at a time. That fails
When compiling all the 5 modules alone. It works!
We also have a "merge"-module. These combines 4 of our 5 modules. This 
merge module compiles without any error, too!
So this is a real strange behavior...

Re: Re-firing a failed/rejected server call in RequestFactory, is this possible?

[Jan Marten]

Thank you for clarifying the behavior.

Nevertheless, in my opinion there is a use-case where the data should be 
reusable after a server failure.

SQL exceptions like a unique constraint violation could be checked before 
sending the request but 
there might be server failures like a non-reachable database which is 
unpredictable.

When something like this happens one could prompt the user to retry after a 
few minutes.
But since the request cannot be reused the user cannot resend it's entered 
data.

Re: Re-firing a failed/rejected server call in RequestFactory, is this possible?

[Jan Marten]

The inconsistency with the current RequestFactory is that if in a batch 
request, a single sub-request has a constraint violation
then onConstraintViolation is called for every sub-request and the whole 
batch request fails (onFailure is called).
Whereas if in a sub-request an exception is raised on the server only for 
this single sub-request onFailure is called and the surrounding
batch-request succeeds with onSuccess.

Thus, the RequestContext cannot be reused since "reuse" is only called for 
constraint violations and failures.

Hence, as described in the original post, after a server failure the proxy 
cannot be reused and the user-entered data is gone (in contrast to a 
constraint violation).

Re: Re-firing a failed/rejected server call in RequestFactory, is this possible?

[Jan Marten]

Is there any progress on this issue?

Issue https://code.google.com/p/google-web-toolkit/issues/detail?id=5794 is 
related and is not fixed either.

RF's behaviour in this regard is inconsistent since an "unimportant" 
retrieval would fail on any ConstraintViolation
in batched requests. It should definitely be possible to batch requests but 
the current API is not sufficient.

A recommendation would be to pull batching out of the RequestContext 
interface and expose it in e.g. a RequestContextBatcher.
A RequestContext is used for one request only and is reusable on failure or 
violation. Thus removing append(), fire(Receiver), etc.
RequestContextBatcher is used for multiple requests.

The specific behaviour in onFailure and onViolation should be discussed 
further.

Transaction settings might make it necessary for all RequestContexts to be 
re-executed or to only re-execute the failed/violating requests.
Therefore it must allow customization by the user.

Re: GWT request factory - Fire request inside of success method of another request

You mean renaming the inner request method? I tried that -> doesn't change

It is not only in prod mode. It's a GWT test case that I run locally.

GWT request factory - Fire request inside of success method of another request

[Jan]

I am trying to nest two request factory calls in each other. I retrieve a 
post object and in the success-method i use the same object again (just for 
testing purposes, I get the same behavior for other request like for 
example persisting).

The problem is: Only the first request reaches the server.

I don't get any error message. If I debug the code, everything works until 
the second request is fired. Nothing happens then. The method on the 
backend is not called, the frontend shows no error, even if I implement the 
"onFailure"-method for the receiver of the second request.

public class RequestFactoryFindTest extends GWTTestCase{

/**
 * must refer to a valid module that sources this class.
 */
public String getModuleName() {
return "com.Test.MyTest";
}

public void test(){
final ClientFactory clientFactory = GWT.create(ClientFactoryImpl.class);
final MyRequestFactory requestFactory = 
clientFactory.getRequestFactory();
final PostRequest request = requestFactory.postRequest();


request.findPost(1l).fire(new Receiver() {

@Override
public void onSuccess(PostProxy response) {


final ClientFactory clientFactory = 
GWT.create(ClientFactoryImpl.class);
final MyRequestFactory requestFactory = 
clientFactory.getRequestFactory();
final PostRequest request = requestFactory.postRequest();

System.out.println("outer success");

request.findPost(1l).fire(new Receiver() {

@Override
public void onSuccess(PostProxy response) {
System.out.println("inner success");

}

});

}
});


}}

Can someone explain this?

Using NumberFormat.setForcedLatinDigits

[Jan Swaelens]

Hello,

I was looking to use this method to force latin decimal symbols. Maybe I am 
doing something wrong but it is not yielding the expected result.
The locale is set to 'en' in the module configuration file, when I 
evaluate LocaleInfo.getCurrentLocale().getLocaleName() on the client this 
yields the expected result.

Making the call to NumberFormat.setForcedLatinDigits with value 'true' and 
formatting some numbers does not yield the expected result of comma as 
decimal separator and dot as grouping separator.

Any tips would be greatly appreciated!

thanks
jan

No symbolMaps created when using collapse-all-properties in module configuration

[Jan Swaelens]

Hi,

I was investigating why our symbolMaps where no longer created and finally 
came to the conclusion that it was caused by adding 
'collapse-all-properties' to the module configuration files.
This is on GWT 2.5.1.

Is this intended behavior? We are using the setting because it greatly 
reduces the time for the gwt compile - is there any way to get the 
symbolMaps while using this property?

thanks!

Re: RequestFactory Could not parse payload: payload[0] = N

I ran into the same problem. With a bit of debugging I found out that I was

GWT HtmlPanel Disable SafeHTML

[Jan Vladimir Mostert]

Hi, is there a way to disable SafeHTML in the new GWT2.5 HTMLPanel?
If I put text in the HTMLPanel, it replaces all my spaces with   which 
means it ignores all styles and also the text just runs out of the page if 
it's long.

Have already posted on StackOverflow as 
well: http://stackoverflow.com/questions/14530012/gwt-htmlpanel-disable-safehtml

GWT - Crawlable (SEO)

[Jan]

Hi,

i like to make my gwt-app searchable by google. I found this article, that 
describes how to do 
it: https://developers.google.com/webmasters/ajax-crawling/

But it does not really make sense to me: If i use a servlet filter to 
present a special view to the google bot: This can not really work on the 
client side. If i change the view with the activties and places pattern, 
this only affects the client side an there is no servlet involved -> 
servlet filter does nothing.

Does some one has an explanation, example or even better a tutorial for me?

Thanks and best regards
Jan

GWT Crawlable (SEO)

[Jan]

Hi

I like to make my GWT-App by the google bot. I found this article 
(https://developers.google.com/webmasters/ajax-crawling/). It states there 
should be a servlet filter, that serves a different view to the google bot. 
But how can this work? If i use for example the activities and places 
pattern, than the page changes are on the client-side only and there is no 
servlet involved -> servlet filter does not work here.

Can someone give me an explanation? Or is there another good tutorial 
tailored to gwt how to do this?

Thanks and best regards
Jan

Re: gwt suggestbox.

[Jan Vladimir Mostert]

Hi, sorry for re-opening a topic from 2009.

In the above code, you said nameCallback = callBack, where is this 
nameCallback being used?
I don't quite understand how to use the callback.

I was just wondering if there's a full implementation / example available 
on how to extend the SuggestOracle using RPC.

public class MySuggestOracle extends SuggestOracle {

@Override

public void requestSuggestions(Request request, Callback callback) {

}

}


// in my ManageSomePageView.java

TextBox textBox = new TextBox();

 horizontalPanel.add(new SuggestBox(new MySuggestOracle(), textBox));



Thanks
Jan

Start method from activationlink

[Jan Philipp Stubbe]

Hi,
I use gwt and try to send an email with an activationlink to an user who 
registered at my application.
I can send the email, but I don't know how the link has to look like to 
call a specific method on the server which finally activates the user.
I found something about RPC, but I think I can't use it to solve this 
problem.
Does anyone have a suggestion how I can handle this?

Thanks

Eclipse GWT Plugin - Display Javascript object properties functionality not working

[Jan Swaelens]

Hello,

We recently discovered the 'Display Javascript object properties' setting in 
the preferences view of the GWT plugin in eclipse.

We are on eclipse Juno (20120606-2254) and also have indigo installations. We 
can't seem to get this very nice feature to work on all our eclipses, only 1 
guy has gotten it to work and he can't recall any special steps he had to take 
before he got it to work.

We are just testing this on the hello world app which is automatically created 
when you create a new gwt project with the eclipse wizard - just to rule out 
any dependencies from our application we are building.

The only thing we are seeing when we inspect a JS object is the 
'hostedModeReference' object with its value and reference sub-fields.

Are we missing something obvious - should we do something else besides enabling 
the setting in the Preferences - Google tab page?

I hope we can get this working as this feature is a major time saver!

many thanks in advace.

Re: printing problem: when I print content of my iframe (I use gwt-print-it) all what is left on the right side of printable page is cut off and stays not printed at all

[Jan Przybylo]

no, I don't want to print double-sided document. 
let me explain it: 
imagine you have empty page with just one big image inside 'body' element: 
 
   


lets say it looks like this:

<http://why.net.pl/tmp/0.png>

and you want to print WHOLE image. So you'd expect your printer to print 
something like this: 

<http://why.net.pl/tmp/1_.png>

but instead of this I'm getting something like this printed: 

<http://why.net.pl/tmp/2_.png>
so it's not whole image. 
of course my problem is not about image but very big HTML form that has 
fixed width and height. This form cannot be resized. Fields on this form 
cannot be positioned differently, they are positioned with absolute 
positioning and they have to stay in their places. 
So my question is: 
   what do I have to do in order to print wide elements that won't fit in 
one page (when it comes to element's width)?

as I previously mentioned I already use gwt-print-it.

printing problem: when I print content of my iframe (I use gwt-print-it) all what is left on the right side of printable page is cut off and stays not printed at all

[Jan Przybylo]

I print big form that has fixed dimensions. If I'd use Letter parer size it 
should fit in 4 pages (2 pages wide and 2 pages high). 
I already started using PrintIt class (gwt-print-it) and it solves most 
basic problems for me. 
But when I try to print whole big form it only prints top left as the 1st 
page and top bottom as the 2nd page leaving the right side not printed. 

Does anyone know proper way of printing wide big pages?

The plugin is installed and activated but still not work. If I try to open

Custom Widget -> Create HTML Element

[Jan]

Hi,

i like to create a Custom widget with javascript, but did not find a
tutorial for this. I tried to create a simple "div" Elment for the
start. But this does not work. Throws some errors. Can someone tell me
some good tutorial on this or give me some tips to correct my code?



package test.client;

import com.google.gwt.user.client.ui.Widget;

public class CustomWidget extends Widget{


public CustomWidget(){
super();
createElement("sdf");

}

public static native void createElement(String msg) /*-{

var newdiv = $doc.createElement('div');
newdiv.setAttribute('id','testid');

newdiv.innerHTML = 'Test Element';
$doc.appendChild(newdiv);
}-*/;

}


Thanks very much
jan

Create local application?

[Jan]

Hi,

is it possible to create a local application which does not need any
server or anything, so i have just a simple javascript/html/file
combination that i can give to someboy and it works?

I tried to compile the gwt sample application and tried to just open
the .html file in the "war" folder, but the button is not shown.

Thank you very much!

GWT, Spring, Hibernate and JAXB in one Application

[Jan Grüßing]

Hi everyone,

I'm playing with the thought of starting a (small?) project to improve 
my programming skills regarding different frameworks. The idea is to 
create an application that let's you manage and evaluate your sports 
activities based on data from GPS sport watches (e.g. the this one 
<https://buy.garmin.com/shop/shop.do?pID=90671&ra=true>) or smartphones. 
It should be able to handle different charts, tables, display 
(Google-)maps and do some calculations. I guess more ideas will arise 
during development. For details check SportTracks 
<http://www.zonefivesoftware.com/sporttracks/>. It does exactly what I want.


Since I have only less than two years of programming experience in 
JavaSE, I am not sure if that goal is out of my league, yet but it feels 
feasable to me.
I read several articles about different frameworks the last days and my 
idea right now is to use GWT for the frontend, Spring to implement the 
MVC architecture and Hibernate to persist the data in a MySQL database. 
The data comes as XMLs. For the beginning, I thought of uploading the 
XMLs manually as files through the frontend and process them on the 
server via JAXB. For later versions an implentation of different browser 
plugins to upload the data directly from the device (e.g. this one 
<http://www8.garmin.com/products/communicator/>) would be very nice to 
have.


Using all these frameworks might be overdimensioned for my intentions 
but as I said: My goal is to improve my skills with some frameworks I 
never really worked with. (The application is supposed to be a nice side 
product ;-) )


Looking at the articles I read until now, I assume it should be 
theoretically possible to combine these technologies. Is this a good 
idea at all? Do you have a better one?
Do you think it is a realistic goal to write such an application as a 
single person regarding my barely existing experience with any of the 
frameworks mentioned above?


Do you have any valuable tips for me? Where to start? Is it necessary to 
draft some kind of design on "paper" before starting the actual coding? 
Or should I just start coding with a more or less existing design in my 
mind?


Or will all this simply end in too much frustration?

I am looking forward to any kind of feedback.
Thank you all in advance!

Regads,
Jan

Problem deploying GWT on IIS and Tomcat

[Jan Thewes]

I've set up an environment where IIS runs on one server and the RPC
endpoints and servlets run on another machine on Tomcat.
The site is available entering http://appName
I've enabled URL Rewriting in IIS so that every call to 
http://appName/appService
is redirected to http://tomcatMachine/appName/{R:0}

The service call are reaching the application on tomcat but the there
i get an error which says that my Class won't be serialized because
MD5.gwt.rpc can't be found.

What am I doing wrong?

Re: GWT Eye Candy - good looking widgets

[Jan Mostert]

Looking good!
A good place to find a close to complete list of possible icons would be the
silk icon library.
Most of the icons look crappy, a rework is definitely in order!

Don't know if you've seen the Vaadin themes:
http://demo.vaadin.com/sampler (also
based on GWT),
that kind of look and feel for vanilla GWT components would definitely make
the GWT Eye Candy project a winner!
I'm actually considering using Vaadin in one of my projects just for the
eyecandy.

Can we still vote for a chapter on RequestFactory?
That would be a deal-breaker :-)

Re: GWT 2.3 + PHP

[Jan Mostert]

I've personally implemented a GWT frontend on a PHP backend using JSON to
pass data back and forth between the server.
GWT makes provision for a large array of methods to connect to the backend,
RPC is just the most convenient way of doing it.

Re: Switching an image by using "OnMouseOverHandler"

[Jan Mostert]

Another vote for the pushbutton, just remember to clear its style, otherwise
its default style will be underneath your images.
Pushbutton supports mouse-over, mouse-down (in the constructor) and mouse-up
(also in the constructor)

Re: GWT + MVP + Spring + Hibernate

[Jan Mostert]

ROO is "just" a console that generates a scaffold for you containing
Spring-MVC code with a JPA (Hibernate) and then you can slap any UI on top
of it, like GWT using the "gwt setup command"

This page will take you through it step by step:
http://www.springsource.org/roo/start

Once you've done the tutorial, you'll have a scaffold in place on top of
which you can work or which you can modify to your liking.

Re: "wait" cursor when calling RPC

[Jan Mostert]

Setting the cursor is not the best design pattern for RPC calls, what if you
have 10 widgets all making RPC calls, will each of them try to set and unset
the cursor?
Also expect some quirkiness between browsers if you set the cursor via the
DOM.

This is probably a better solution, show and hide some animation over a
component that is busy: http://www.ajaxload.info/

Compiled GWT code runs clientside, on the serverside (which can be anything

Re: CssResource compilation problem

[Jan Mostert]

Maybe selectedTabCenter is out of scope here or doesn't have a value at
compile time yet?

Re: how to remove the vertical bar in the listbox

[Jan Mostert]

I was going to suggest adding some CSS to it: *overflow-y:hidden; *but that
doesn't appear to work on my side.

The one in the docs is created outside ui:binder and appears to be without
the vertical scrollbar
http://www.gwtapps.com/doc/html/com.google.gwt.user.client.ui.ListBox.html
[image: ListBox.png]

Also curious to see a ui:binder workaround for this.

Re: isDeployed function

[Jan]

I also thought so. Then I introduced the following code into the
service implementation:

isProdMode = GWT.isProdMode();
System.err.println(isProdMode);

Afterwards I deployed it to AppEngine and the result was:

2011-02-16 01:18:09.137 [...].: false

I suppose that the isProdMode() function is designed for client code
since it is located inside

com.google.gwt.core.client.

However my question referred to the server side.

Anyway, thanks for your help

isDeployed function

[Jan]

Hi,

I have some code on the server side of my application which should
only be executed locally in development mode.
Therefore I would like to have an isDeployed()-function to control
whether or not it should be executed.
Does anybody know of such a function or is there even a way to remove
such code parts like it is the case for assert?

Thank you very much
Jan

Re: GWT debuggin in Chrome - why is so slow?

[Jan Mostert]

A DockLayoutPanel is being used in the generated scaffold, which means that
if it's breaking in IE when using transitional (as mentioned in the docs),
the generated scaffold will not work properly in IE.

Re: GWT debuggin in Chrome - why is so slow?

[Jan Mostert]

Thanks Jeff, this will save me plenty of headaches later this year when I
deploy my app, the default generated by Spring Roo uses transitional even
though the docs explicitly says that the doctype should be 

Is this something that I need to log with GWT or with the Spring guys?

The GWT 2.0 layout system is intended to work only in "standards mode". This
means that you should always place the following declaration at the top of
your HTML pages: 
What won't work in standards mode?

As mentioned above, some of the existing GWT panels do not behave entirely
as expected in standards mode. This stems primarily from differences between
the way standards and quirks modes render tables.

Is that for all layout panels (the simple ones like horizontal and vertical

panels like DockLayout?

Re: GWT debuggin in Chrome - why is so slow?

[Jan Mostert]

@Edson, what operating system are you using out of curiosity?
I take it the debug mode you're talking about is "development mode"?
I've been using the development mode plugin in Chrome in both Gentoo Linux
and Kubuntu since December 2010, before that I was having problems as well -
maybe upgrade your Chrome?

@Eric, do you still have that IE-buggy code?
Would you mind testing this doctype for me:

Re: Image handling using ClientBundle

[Jan Mostert]

Your path is wrong, it should be relative to file where you import the image
eg:

main/java/com/myproject/client/scaffold/ui/widget/somecomponent.ui.xml


and the image is located in
main/java/com/myproject/client/style/images/Universal-frame_mod_tl.png

That @Source should probably have a path of "../
public/resources/cut_icon.gif"

Hope it helps :-)

PS, is there a better way to do this, eg force an absolute path somehow?

Re: Considering using Google Accounts for authentication. Good idea?

[Jan Mostert]

Spring Security should take care of most of those requirements since it
already has openID support built in, but that will require authentication to
happen outside your GWT application (I'm a bit paranoid exposing my
javascript if people aren't authenticated) and if you really need the login
to be in GWT, Vaadin does some serverside magic that will allow you to build
a secure login form using GWT.

Re: How to Display a Loading message when transitioning between Activities and Places ?

[Jan Mostert]

I haven't done this myself, but I've seen it being done with the generated
scaffold in Spring Roo.

Generate a sample application using Spring Roo using the provided sample
script and the output code should have a working example for you. Will have
a look for you later tonight if you don't manage, should have some generated
samples at home.

Re: How to Display a Loading message when transitioning between Activities and Places ?

[Jan Mostert]

Simply take a div that says loading, when you start the transition, set its
css style to be visible and when you're done with the transition hide it.

Re: Export CellTable's selected rows into a csv file

[Jan Mostert]

I'm assuming you're using a JAVA backend hence the RPC?
Which one are you using if I may ask?

You'll need to set the mimeType in the header you're sending, saw a topic on
Stack Overflow some time ago, have a look at this:

Re: Spring ROO GWT with GIN injection on widgets created by ui:binder.

[Jan Mostert]

It feels like I'm working in circles, one module needs something from
another module and that one needs stuff from another module etc etc etc
Here's my updated code using the container method:

*RorPresenter.java*
*
*

> public class RorPresenter {


> private RorView view;

public void setView(RorView view){

this.view = view;

}


> @Inject

public RorPresenter(){

bind();

}


>
> public void doMyClickEvent(){

Window.alert("FIT");

}


> public void doYourClickEvent(){

Window.alert("MEH");

}


> public void bind(){}

}


*RorView.java*
*
*

> public class RorView {


> interface Binder extends UiBinder {}

private static Binder BINDER = GWT.create(Binder.class);


> private RorPresenter presenter;


> @Inject

public RorView(RorPresenter presenter){

this.presenter = presenter;

presenter.setView(this);

presenter.bind();

}


> @UiHandler("myButton")

void onMyButtonClick(ClickEvent event){

presenter.doMyClickEvent();

}


> @UiHandler("yourButton")

void onYourButtonClick(ClickEvent event){

presenter.doYourClickEvent();

}

*RorContainer.java*

private static Binder BINDER = GWT.create(Binder.class);

RorView view;

@UiConstructor

public RorViewContainer(RorView view){

this.view = view;

initWidget(BINDER.createAndBindUi(this));

}


> @UiFactory RorViewContainer makeRorViewContainer(){

return new RorViewContainer(this.view);

}

}


And now I use * *in the applicationscaffold's xml
configu.

It doesn't like the paramaters in the constructor and the @UiFactory doesn't
fix it
[ERROR]  missing required attribute(s): view Element
 (:156)

Jeff, can I mail you my maven project sample code, it'll be easier to show
the problem if you have the whole context under eyes, been struggling to
bind the view and the presenter for literally weeks now, just need one
working example.

Thanks

Re: Spring ROO GWT with GIN injection on widgets created by ui:binder.

[Jan Mostert]

I'm not sure which MVP framework I'm using, I'm basically using whatever
framework is being generated by Spring ROO after using the "gwt setup"
command and since this is my first time using GWT since pre version 1.5, I'm
pretty lost.

That would probably work under normal gwt, but the component needs to be
added via ui:binder, so can't do that fancy footwork of manually creating it
and then adding it to RootPanel unless there is a way of doing it the
ui:binder way?

In ScaffoldDesktopShell.ui.xml I'm inserting the component via xml:

[code]
http://dl.google.com/gwt/DTD/xhtml.ent";>




@def contentWidth 850px;




...
**



[/code]

The ScaffoldDesktopShell itself looks like this:

[code]
public class ScaffoldDesktopShell extends Composite {
interface Binder extends UiBinder {
}

private static final Binder BINDER = GWT.create(Binder.class);

@UiField SimplePanel details;
@UiField DivElement error;
@UiField LoginWidget loginWidget;
@UiField SimplePanel master;
@UiField NotificationMole mole;
@UiField(provided = true)
ValuePicker placesBox = new
ValuePicker(new ApplicationListPlaceRenderer());

public ScaffoldDesktopShell() {
initWidget(BINDER.createAndBindUi(this));
}
public SimplePanel getDetailsPanel() {
return details;
}
public LoginWidget getLoginWidget() {
return loginWidget;
}
public SimplePanel getMasterPanel() {
return master;
}
public NotificationMole getMole() {
return mole;
}
public HasConstrainedValue getPlacesBox() {
return placesBox;
}
public void setError(String string) {
error.setInnerText(string);
}
}
[/code]

PS, will attached code be displayed?

Re: GWT + JSP = AdSense-Content?

[Jan Mostert]

I haven't seen anyone doing a full-on system with "html" pages and GWT
widgets, but it can be done, even though I personally think GWT was not
designed for this.
Maybe have a look at the hash-bang ( #! ) as an option, Google bots have a
special way of indexing pages using hashbang (they send a special type of
request to root page which you can then handle and send back different
content specially crafted for the bot, don't know if adsense will work in
the same way

Re: GWT + JSP = AdSense-Content?

[Jan Mostert]

I'm currently bootstrapping a GWT application with a JSPX page, the pages I
want to have indexed are pure JSPX pages, the backend page is a JSPX page
with GWT widgets being placed inside divs.
It won't be much slower than a regular JSPX page, except for the
GWT-javascript that needs to be loaded with each page load.

Re: Spring ROO GWT with GIN injection on widgets created by ui:binder.

[Jan Mostert]

Hi Jeff, how and where do I need to retrieve the view from the presenter and
does the binding happen automatically when I do that?
Do you perhaps have a sample snippet of code that will make the binding
happen?

Those clickHandlers I'll clean up after I got this simple prototype working
(this GIN / Guice magic is still very new to me), thanks :-)

Re: RequestFactory & JPA: Does the table has to has a field called Version?

[Jan Swaelens]

This is an extract from a post that helped me a lot:

If you can implement a single Locator class that works for all your
entities, then go with it; and otherwise make one for each entity.
For instance, if you have a base class for your entities that provides an ID
and version, then you can easily cast any entity to that class to implement
getId and getVersion, and you probably can implement getIdType by returning
a fixed type.
You can clazz.newInstance() in the create() or use
PersistenceManager#newInstace with JDO.
And you can easily "find" using the Class and ID with JPA using
EntityManager#find(clazz,id), or with JDO using
PersistenceManager#getObjectById(clazz,id).
 
Basically, you could very well have only one Locator class per "id type".
 
Oh, and something to keep in mind: the Locator and *your services* instances
(not the ServiceLocator instances though) are cached aggressively and reused
for all subsequent requests, so make sure they are thread-safe !
(have a look at the ServiceLayerCache class to see all "memoized" methods)

Re: RequestFactory & JPA: Does the table has to has a field called Version?

[Jan Swaelens]

You do not need to do that, the RequestFactory comes with a concept of 
'Locator's which help you to overcome this issue.
Have a look here for the Locator documentation: 
link
And have a search in the archives of this group, you can find some examples 
that should help you along.

Re: Controlling the loaded object graph when using EntityProxy instances with latest RequestFactory feature

[Jan Swaelens]

I can sure do that, I will be generating the proxy classes anyway which 
means that I can add the list of properties at that time.
Very good suggestion, thanks!

Re: Controlling the loaded object graph when using EntityProxy instances with latest RequestFactory feature

[Jan Swaelens]

Hello David,

There are about 15 of these complex data types, new ones are only added once 
in a blue moon which means that adding a value proxy when that happens is no 
big deal. I am fine with writing a proxy for all of our data types, no 
problem there.

The 'issue' that I am trying to get around is the fact that my DTO object 
(MySessionDTO in the example above), which has a number of embedded objects 
(MyInteger, MyString - all of them have a value proxy: MyIntegerProxy, 
MyStringProxy) doesn't include its embedded objects automatically when the 
DTO is sent to the client. I need to explicitly state that they need to be 
sent to the client too by using this kind of statement: '
mySessReq.startSession(textToServer).with("userName").with('lastLogonDate').with('expirationDate')
 
...'.

What I want to achieve is that I can simply use these kind of statements 
'mySessReq.startSession(textToServer)' 
and have the embedded objects sent to the client (as if they were simple 
types like Integer, String ...). From my point of view, these 'complex data 
types' aren't really embedded objects, they are rather 'embedded properties' 
which make up the DTO object than an embedded object which represents a 
relation towards another domain object.

Now, I did manage to get this working by also making my *MySessionProxy *(the 
proxy for the DTO object) extend ValueProxy instead of EntityProxy. I 
now have value proxy objects for both my DTO's and the complex data types. 
Is this still a valid approach or am I going to run into troubles further 
down the road? This approach means that I no longer have a containing entity 
which manages versioning and identity.



Thanks a lot for your feedback on this!

Re: Controlling the loaded object graph when using EntityProxy instances with latest RequestFactory feature

[Jan Swaelens]

Further digging in the source code brought me to the *
com.google.gwt.requestfactory.server.Resolver* class where the decision is 
made to send or don't send a certain property. More specifically the '*
resolveClientProxy*' method where the '*AutoBeanVisitor*' is used to iterate 
over all the object properties/attributes.

This code extracts documents the conditions which will allow a property to 
be sent or not:

*/*
 * Send the property if the enclosing type is a ValueProxy, if the 
owner
 * requested the property, or if the property is a list of values.
 */
Class elementType = ctx instanceof CollectionPropertyContext
? ((CollectionPropertyContext) ctx).getElementType() : null;
boolean shouldSend = isOwnerValueProxy
|| matchesPropertyRef(propertyRefs, newPrefix)
|| elementType != null && ValueCodex.canDecode(elementType);

if (!shouldSend) {
  return false;
}*

This learns me that I can get this working by:

   1. Modify my DTO to extend ValueProxy instead of EntityProxy
   2. Add the property names in the 'using' clause of the invocation 
   statement
   3. Hack ValueCodex to also include my 'complex data type' objects
   4. Get lucky and get access to some override mechanism in a future 
   version which would allow me to hook some code up to influence the 
   'shouldSend' value based on the 'domainEntity' and 'newPrefix' values
   

The additional questions which pop up in my mind are as follows (same 
order):

   1. What are the consequences? Because value proxy lacks the version/id 
   features as employed by entity proxy there must be some magic which is lost. 
   Is it only increased bandwidth because the object needs to be sent back 
   instead of only changes? 
   2. Not an option
   3. This is probable frowned upon :-)
   4. Maybe as questionable as the previous point?
   

Thanks a lot for your thoughts on this!

Controlling the loaded object graph when using EntityProxy instances with latest RequestFactory feature

[Jan Swaelens]

Our application uses an object model with DTO's which contain objects (what 
we call complex data types) that make up the 'properties/fields/attributes' 
of a domain object. This means that we do not use Integer, String ... but 
have a customized MyInteger, MyString, MyDouble variants instead. These 
complex data types wrap the native object and add some additional properties 
too.

To illustrate, this is a simplified version of one of our DTO objects:

*public class MySessionDTO implements IMyDTO {

* * private MyInteger id = null;
private MyString userName = null;
...
}*

 
I created a proxy implementation for this DTO which looks like this:

*...@proxyfor(value = MySessionDTO.class, locator = MyEntityLocator.class)
public interface MySessionProxy extends EntityProxy {

public MyIntegerProxy getId();

public MyStringProxy getUserName();
}*


Using this set-up I can perfectly retrieve the values (in this sample the 
user name) which I require on the client side using the request factory 
feature as follows:

*MySessionRequest mySessReq = requestFactory.mySessionRequest();*
*Request startSessionReq = 
mySessReq.startSession(textToServer).with("userName");*
*startSessionReq.fire(new Receiver() {*
**
*}*


This approach (using the .with method to retrieve all properties of our DTO 
objects) is fine from a functional point of view. The problem is that our 
DTO's have many of these properties and from time to time new properties are 
added to the objects. It is not feasible to go trough the code each time to 
implement these changes nor is it feasible to list all properties for each 
call to fetch the contents of our objects.

I am wondering that there is some way which will allow me to indicate which 
(embedded) objects are retrieved when a certain DTO is being pulled to the 
client side. Having looked at other posts in this group I can only conclude 
that many other developers are facing this problem, which leads me to 
believe that our approach is not that exotic.

I do agree that this is a no-issue for the more traditional approach where 
objects are only used inside other objects to represent real domain objects.

*(I already posted a similar topic as my first post to this group but it 
never made it to the actual mail group, apologies if it was rejected for 
some reason which means that I am double posting this - if this is the case 
could you please notify me)*

EntityProxy with complex data types

[Jan Swaelens]

Our application uses a concept of 'complex data types' to represent 
values/properties of an object. Simply put, we have a 'MyInteger' variant 
for 'Integer' values, a 'MyDouble' variant for 'Double' values  (none of 
them actually extends these types, they are rather wrappers). Our data 
object thus contain a number of fields who are all typed as these 
'MyInteger', 'MyDouble' types.

I am trying to re-use our data model objects as entity proxies, which is 
working fine except that the values of these 'fields' are only returned when 
I use the '.with("propertyName")' method on my request context instance.
That approach is not really workable for me as we have many of these fields 
on all of our data objects.

I do understand that in many cases, the experienced behavior is actually 
what you want (=retrieve objects on demand).

I have done some digging around in this group as well as on the internet in 
general, but was not able to find a solution for my problem. I was hoping 
that anyone from the GWT team has some input on how I can get around this 
behavior.

Many thanks!

Implementing a ServiceLayerDecorator

[Jan Swaelens]

I am experimenting with the RequestFactory and came to a point where I
want to create my own ServiceLayerDecorator.

I have read trough the available documentation and found that I need
to hook my custom service layer decorator up by calling this method
with an instance of my decorator: 'ServiceLayer.create()'.

The code which I have implemented looks like this:

ServiceLayer serviceLayer = ServiceLayer.create(new
MyServiceLayerDecorator());
SimpleRequestProcessor processor = new
SimpleRequestProcessor(serviceLayer);
final EventBus eventBus = new SimpleEventBus();
MyRequestFactory f =
RequestFactoryMagic.create(MyRequestFactory.class);
f.initialize(eventBus, new InProcessRequestTransport(processor));

Now, I tried to run with this code implemented in the 'onModuleLoad'
which is not working (it is referencing server classes and giving the
expected 'source not found for class ABC' errors). I came up with the
idea to implement the code there because my old request factory
initialisation code was also located there.

I am wondering where I need to invoke the 'ServiceLayer.create'
related code in order to get this working.

Thanks a lot for your help!

GWT Native Java Script Method Error invalid argument

[Jan]

Hi all,

In my actual GWT Project, i have a strange error. I have a native
Javascript method for resizing the div, where my google map is in it.
The method works fine in the normal browser, but as soon as i run it
in the hosted mode, i get an error.

The method is:

public static native void adjustMapToBrowserWindow() /*-{
var mapDiv = $doc.getElementById('map');
var drivenWayDiv = $doc.getElementById('drivenWay');
var drivenWayAnimatedDiv = $doc.getElementById('drivenWayAnimated');

var offset = 130;
var paddingOffset = 50;

var windowHeight = $wnd.innerHeight;

var mapHeight = windowHeight - offset;
var formHeight = windowHeight - offset - paddingOffset;

mapDiv.style.height = mapHeight + 'px';
drivenWayDiv.style.height = formHeight + 'px';
drivenWayAnimatedDiv.style.height = formHeight + 'px';
  }-*/;

The error Message is:

com.google.gwt.core.client.JavaScriptException: (Error): Invalid
Argument.
 number: -2147024809
 description: Invalid Argument.
at
ch.zhaw.geotagging.web.client.GeoTaggingMain.adjustMapToBrowserWindow(Native
Method)

79)
at
ch.zhaw.geotagging.web.client.GeoTaggingMain.onModuleLoad(GeoTaggingMain.java:
32)

I can't figure out, which line causes the error, because ther is no
line number. Nr. 32 and 79 are only the calls of the method..I really
need the hosted mode for debugging, and as long as i have this error,
thats not possible.

I appreciate your help.

Thanks and with best regards.

Re: Assertion Error when adding an element to the root panel

So the problem is, because i try to access my div  "drivenWayContent",
which is subelement of my div "drivenWay"? But how else can i get
access for all the div's which are not on the top level of the
structure?

Assertion Error when adding an element to the root panel

[Jan]

Hello Everybody,

In my actual GWT Project, i have a User Interface with different
widgets. Because we continued the project from another person, we were
not able to take the newest GWT Version, so our Application is with
GWT1.7.

Now when i start my application normally, everything works. But as
soon as i start the application in the hosted Mode for debugging, i
get the follogwing error:

[ERROR] Unable to load module entry point class

The code line in the error report (at

97))
 is not the first line, where we use the "
RootPanel.get("xx").add(xx);" Method, so i really don't get it, why
the error comes at this line. I searched with google to find some
solution, but i didn't understand, why i have this error..

If somebody has an idea..

Thanks and with best regards.

Re: How to add multiple markers out of Array

[Jan]

Hi,

In my Array of Lists are the Points (LatLng Objects) saved, from which
I need the first point of every List to create may marker. My markers
are saved in the array shipMarkers of type Marker, which is defined
globaly.

How to add multiple markers out of Array

[Jan]

Hi Everybody,

For my actual GWT Project, i need to add markers on my map. The number
of markers depends, it could be 0-3 of them. I get the datas for the
markers out of my database and in an array. Now i created a method,
witch has a for loop in it. In the for loop, i create the marker and
add it to the map. When i run my application, it stops at the line
"map.addOverlay(shipMarkers[i]);" but there comes no exceptions in the
debugging mode, it only stops and does nothing. I found that out,
because i have a textbox in my UI, where i can give some messages out.
As soon as i remove the line map.addOverlay(), my programm runs to the
end and works perfectly, but without markers..

Here is the code of the method:

private Marker[] getShipMarkersFrom(LinkedList[] latLng) {
shipMarkers = new Marker[latLng.length];

for(int i = 0; i < latLng.length; i++) {
  Icon iconAnimation = Icon.newInstance(baseIcon);
  iconAnimation.setImageURL("marker_pictures/
ship_marker.png");
  MarkerOptions optionsAnimation =
MarkerOptions.newInstance();
  optionsAnimation.setIcon(iconAnimation);
  LatLng latLngPoint =
LatLng.newInstance(latLng[i].get(0).getLatitude(),latLng[i].get(0).getLongitude());
  shipMarkers[i]= new Marker(latLngPoint, optionsAnimation);

  map.addOverlay(shipMarkers[i]);
}

return shipMarkers;
}

I'm searching now for more than 3 hours because of this problem. I
would be really happy, if anybody can help me.

Thanks and best regards.

Jan
