Re: The RequestFactory ValidationTool must be run for the RequestFactory type

I too have been banging my head for RequestFactory error 'The
RequestFactory ValidationTool must be run for the '. I too have
requestfactory-apt.jar on buid path. Done checking eclipse('helios')
for annotation processing. I am quite frustrated at all and thinking
on moving over gwt. Do we have any explicit way to revoke the
validation tool or any straight solution to the problem like working
from command line to run Validation tool or are there any parameters
to give in run config. Please help!!! any link, any reference on net
to explain in depth what is this validation tool and why n how it
works. SOS!!

I don't know about this story, but if that would be the case, then GWT 
will be just "WT". I think many people have checked-out the GWT source 
and even Google would no longer officially support it, I think the 
community will still be there. Unless there comes a better way of 
translating Java to Javascript code. Cheers.

Can someone explain the authentication logic in GWT apps ?

Anyone explain the entire authentication and authorization logic in

Session management in Ajax applications ?

If you don't want to bother yourselves with explaining and code

Thank you very mush.



Hi, first I think you should read up about GWT-RPC topics and try some 
codes first. However as for your question it's very simple if you 
already understand RPC (although there are other ways than RPC to do this):


- Create your Service and Async on the client side
- Implement the service on the server side. If you are using GWT RPC, 
this class will inherit from RemoteServiceServlet and eventually inherit 
from Servlet.
- Just put the authentication logic there (in that RPC servlet), 
verifying user credentials against a database and placing session 
objects on the Service implementation, its that simple

Your project out of the box was created by the plugin with a directory
structure as follows:

/client
/shared
/server

The class you created will reside under the server package. Anything
in the /client and /shared will eventually get compiled down to JS. So
in your server you do all your crud operations and return data back to
the client.

You should load "layouts" without much logic on it so the GWT designer 
will not have hard time drawing up the widget. I mean, in my case my UI 
are pure UI (no logic, MVP pattern) so GWT designer have no problem 
rendering the widget. In case your are using UiBinder you should open 
the ui.xml file and not the .java part of the UiBinder code.

Re: Please help with CellTable

[Alfredo Quiroga-Villamil]

Hi Blake:

I will try to take a look later at 1 and 2, they are CSS controlled.

For now:

4. See below for an example:

MultiSelectionModel multiSelectionModel = new
MultiSelectionModel();
CellTable cellTable = new CellTable();
cellTable.setSelectionModel(multiSelectionModel);

3. Handler for the selection model below:

// Handler
cellTable.getSelectionModel().addSelectionChangeHandler(new
SelectionChangeEvent.Handler() {
@Override
public void onSelectionChange(SelectionChangeEvent event) {
Set selected = ((MultiSelectionModel)
cellTable.getSelectionModel()).getSelectedSet();
if (selected != null) {

}

}
});

Hope it helps.

Regards,

Alfredo

Re: Google axing GWT?

[Paul Stockley]

It looks like the GWT guys who left to go to new startups are still using 
GWT. This bodes well for future support even if Google isn't directly 
involved anymore.

Please help with CellTable

[Blake McBride]

Greetings,

I need a sort of listbox where each row is made up of several columns.  I
don't want to edit the data in the listbox.  I just want to select one or
more rows, click a button, and be able to know which rows were selected.
 Looking around it seems like CellTable is close.  I put it together as
described in the various examples.  It works as described but not how I
want.  Specifically:

1.  I would rather each row not be shown alternately light blue and white
background.  I want the rows all displayed with a white background.


2.  While I can select individual row (they get highlighted in yellow), it
also places a border around the column within the selected row.  I am not
editing the column within the row.  I just want to select the row, not the
column within the row.  How can I configure it to just highlight the
selected row and not add any borders?


3.  When a row is selected, how can I tell which one is selected
programmatically?


4.  How can I control single / multiple row selection?

Thanks for the help!

Blake McBride

Re: Server detection of client crash

[Alfredo Quiroga-Villamil]

Thanks. I think Joseph said it before and I agree with him. If it's
something of that nature, I would likely try to stay from web stuff.
However, that doesn't mean is not possible or there are no ways to
ensure what you want.

I recently had the chance to speak with a few guys at RedHat about a
project they have been working on based on GWT. I've been meaning to
let people know about it because I was really impressed by a couple of
things I saw. One of them can truly help you and make your requirement
easier or a lot easier to implement.

http://www.jboss.org/errai

A few things:

a) You don't need jboss to use it.
b) Take special attention to CDI (crazy cool and useful).
c) They've done something really interesting where you truly have a
transparent web/server application, blurring completely the lines
between server and UI. Via an annotation you have Server Push. Their
Dependency Injection I thought was also nicer than GIN for the UI.
Although I use GIN and love it!

So what you could do, assuming that you truly want to keep this web
based is to have the server contacting the UI every x amount of
seconds. If no response is received from the UI, then you know that
something is not right. That would be better I think than polling the
server.

Again, this could be done without errai, but take a look at it if you
get a chance.

Best regards,

Alfredo

Re: How to stop the move to Place

[Alfredo Quiroga-Villamil]

Interestingly enough, have to admit, I don't see at a glance unless I
am missing something an easy way to accomplish what you need.

We need something to completely halt execution and act upon the result
of the action/handler (ok or cancel result for example), which is
ultimately what the PlaceController is doing via a DefaultDelegate
using a Window.confirm in mayStop.

I will try to make some time over the weekend and look into this.
Hopefully we are both just missing the obvious and there is an easy
solution to it and someone will respond to the thread with it.

Regards,

Alfredo

Re: Server detection of client crash

[mmorckos]

What I meant by "crash" is that the client doesn't "cleanly". For
instance, the user can simply close the web-page, or the client's
machine can lose connection to the server. I'm asking if there is a
way that the server can detect that instantly (some sort of a
heartbeat ping between the client and the server, unlike a session
timeout).

Re: Google axing GWT?

[Daniel Mauricio Patino León]

I think GWT its a very good open source project. We use it to develop RIA
and we love it. Like  Joseph i'll pray to google make it better and improve
it.
What about a thread where people +1 if want that google keep working on it?
there  exist one?

Re: Call for action: Time to rethink a road-map and more frequent updates for GWT.

[Steve]

Don't know if anyone has posted this link yet, but here goes.

Not quite a roadmap, but it IS signs of external communication. :) I'm not 
as worried anymore.

I'm betting that we'll see some really cool stuff out of IO.

Re: where to place css file and image file?

[Joseph Lust]

For CssResource and ImageResource users, I find this the most robust way to 
place these files:

*com.myPackage.moduleA.resources (put resource interfaces here)
*com.myPackage.moduleA.resources.images (put image files here)
*com.myPackage.moduleA.resources.css (put css files here) 

The real payoff here is that:

   1. Each module is self contained with all its css/images. Try pulling a 
   module's resources of out a public folder shared by 10 modules.
   2. You can more easily use this module in a different GWT project.
   3. Since you're not using a public folder, only the used 
   selectors/images get compiled into your output war. Saves a lot of 
   time/bytes.

You might ask "What images used in multiple modules?" In our apps we have a 
"common" module with these parts.

Hope that helps.


Sincerely,
Joseph

Re: UIBinder: Overriding obfuscated CSS styleNames

[Joseph Lust]

On reading your problem, I became curious how this is achieved.

According to the following article, you can do this using the interfaces.
http://stackoverflow.com/questions/5943895/how-exactly-would-one-override-a-cssresource
 

So, you'll need to use the interfaces in your UiBinder.

Something like:

# put this in your new widget's java class
interface CustomStlye extends ToggleButton.Style
{ 
@Override
public String down(); 
}

# put this in the UiBinder of your new widget
 
.button .down { 
   background: #fff; 
} 



Let me know if this works for you. I don't have the time to make a module 
to test this on?

Sincerely,
Joseph

Re: Runtime exception: com.google.web.bindery.requestfactory.server.UnexpectedException: Could not find static method with a single parameter of a key type

[Thomas Lefort]

You do have to read the doc carefully indeed. I got stuck for a little 
while, I thought I could get away by simply using "find" but no you need to 
use "findEntity", ie replace Entity by your entity name. This got me, 
because at first it worked with a single entity, but when I had two 
entities with relationships, it wouldn't work anymore. By changing the 
method names to respect the convention mentioned above, it worked fine.

Re: How to use image in global css

[Joseph Lust]

To start with, I like to utilize the public/ folders in my packages for 
storing these values. That way, if you put images in any public/images/ 
folder  (I put a public/ folder in every module), they will end up in your 
war in the images/ folder.

First make sure that the above is working correctly for you. You can also 
utilize an ImageBundle which will assure you the images are available 
through compile time checking. I find this the best solution.

With an ImageBundle your rule becomes:

@sprite
.rule1 {

gwt-image:'img1';

}


To investigate this further use FireBug or Chrome dev tools to find what 
image resource your .rule1 is pointing at. That will probably reveal the 
problem.


Sincerely,
Joseph

Re: Thoughts on User defined time in the UI

[Joseph Lust]

Check out how this is done in ExtJs. Basically you just set a listener for 
the character entry to the textbox. You set a regex that is looking for 
something like *\d{1,2}:\d{2}:\d{2}* to confirm that people are entering it 
as desired. Then I just have 2 functions called sec2time() and time2sec() 
so that I can pass the time as seconds back to the server.

This is how I do this for time entry on 
RunPartner.com, 
but you've have to be a member to play with that widget. I'm working on 
converting it to GWT, but it's still ExtJs for now. I'll throw the time 
widget source up when I get it in GWT.

Joseph

Re: How to stop the move to Place

[st1ll]

The situation is the following:
1) There is a table cell which can be edited
2) the user has not saved the changes, and clicks on any item on the 
navigation menu (try to move to another page)
3) You receive a modal window with the message - "There are unsaved changes.
 Do you want to keep them?" There are three buttons - "Save," "Do not Save", 
"Cancel"
4) By clicking the "Save" button, the data is sent to the server and takes 
you to a page that the user has selected previously on the menu
5) If the button is pressed, "Do not save" just takes you to a page that the 
user has selected previously
6) If you press "Cancel" modal window just closes, switching to a different 
page is not carried out

I'm sorry to write in English until I get bad, so to understand my speech can 
be hard :)

Thanks for the answer.
This method (mayStop()) is not suitable to me for one reason - I need to get

Save" at the touch of which happened to save the data into the database.
I have not found a way to make non-standard window, caused by this method

Re: Thoughts on User defined time in the UI

[Alfredo Quiroga-Villamil]

I don't recall seeing a TimePicker in GWT. I do recall seeing one and
I found it in the GWT incubator (URL at the end of my response).

Options:

a) Create something fairly simple now to get the job done. Three
SelectionCell's if you want the values to be unmodifiable and save
yourself the trouble of validation if you used TextBoxes. This is
perhaps one of the simplest ways to go.

b) Create something a bit more sophisticated.

c) Take a look at the previous incubator implementation. It's GWT
only, so you might be able to resuscitate it and use it.

Re: Dynamic CompositeCell

[Alfredo Quiroga-Villamil]

If you have an "n" number of values that should be represented in one
single column, I would go for a tree. Its ability to expand nodes when
needed, gives the user a chance to have it expanded or collapsed. So
in your case the column would contain:

"Top Of Tree"
  CheckBox 1
  CheckBox 2
  CheckBox 3
  CheckBox n

Alfredo

Re: How to add External Java Classes to GWT Project?

[Alfredo Quiroga-Villamil]

Danish:

Your project out of the box was created by the plugin with a directory
structure as follows:

/client
/shared
/server

The class you created will reside under the server package. Anything
in the /client and /shared will eventually get compiled down to JS. So
in your server you do all your crud operations and return data back to
the client.

Regards,

Alfredo

Re: Dynamic CompositeCell

[Derek]

I personally would just create a new cell, but I'd probably start with
CompositeCell for a starting point.

Re: How to stop the move to Place

[Alfredo Quiroga-Villamil]

Hi:

I am not 100% sure what you are trying to do, but in your current
activity, you can override "mayStop()". That would be one possible way
to intercept and potentially cancel going to a new place.

If that doesn't do what you need, please provide a little example of
what the ultimate goal is to see what options are available depending
on your use case.

Best regards,

Alfredo

Re: Request Context clear queue on method invocations when onConstraintViolation is called

[Jens]

Don't enqueue requestContext.saveMember(..).to(..) in the save button 
ClickHandler. Do it once when you start editing the proxy and in your 
ClickHandler you only need to do editorDriver.flush().fire().

Re: Preventing selection event propagation

[Jens]

Tab(Layout)Panel's SelectionEvent is a GwtEvent and not a DomEvent, so its 
only a logical event fired by GWT and not a native event fired by the 
browser. Thats why you don't have a stopPropagation() / preventDefault() 
method.

But TabPanel and TabLayoutPanel have an addBeforeSelectionHandler() and the 
BeforeSelectionEvent contains a cancel() method which should cancel the 
upcoming selection. This should help you to solve your problem.

Re: Preventing selection event propagation

[Ashwin Desikan]

Do u use activities in your app? If yes do you have an activity mapped to each 
of your tabs? You have a mayStop method in activities which can be used to stop 
the user from navigating from current activity.

How to stop the move to Place

[st1ll]

Hello.
I need to create model window, which appears, when I try to go from
current page via links.
I may initiate the creation of window into onPlaceChangeRequest
(PlaceChangeRequestEvent.Handler ()).
But I dont know, how to interrupt the process of transition.
It is possible?

Re: Can UI components be tested through JUnit/GWTTestCase?

[Clint Gilbert]

-BEGIN PGP SIGNED MESSAGE-
Hash: SHA1

I've been able to test Widgets with JUnit in a project I'm working on.
I'm able to make widgets, see that they respond to external events
(notifications about state they observe, or event types they're
subscribed to via an EventBus, that sort of thing), and even send UI
events to them:

final MyWidget myWidget = new MyWidget(...);

myWidget.someButton.fireEvent(new ClickEvent() { });

//assert that the right things happened

The anonymous subclass of ClickEvent feels a little hacky, but it works
for us because our widgets (for the most part) just care that they got
clicked, they don't care about x and y coords, etc etc.

Writing the tests was relatively straightforward, but getting them to
run as part of a Maven build took some doing. A pom with all the
necessary incantations is here:

https://open.med.harvard.edu/svn/shrine/trunk/code/webclient/pom.xml

I don't know if that's minimal or not; I started with what was generated
by the gwt-maven-plugin, and tweaked the pom until it did what I wanted.
:/  We use a TestSuite (ugh) and follow the naming conventions for test
classes and suites recommended by the gwt-maven-plugin docs.

Request Context clear queue on method invocations when onConstraintViolation is called

[Alex Vakaloudis]

To perform save  in a view I am using RequestFactoryEditorDriver to flush 
any changes to a RequestContext and then I call 

save(the edited proxy).to(MyReceiver).fire();

MemberRequest s = (MemberRequest)editorDriver.flush();
MemberProxy sectorProxy = (MemberProxy)getProxy();
s.saveMember(sectorProxy).to(new MyReceiver()).fire();

MyReceiver has a onConstraintViolation method which displays violations 
generated in the server. I am using my own 
 ServiceLayerDecorator.validate() to check for any business-related 
constraints.

To this point it works fine. However when after more than one attempts the 
user "fixes" all violations and the entity reaches the service, the save 
method is invoked multiple times (as many attempts it took to pass 
validation). I understand that  this is because the request context is 
queuing all method invocations and by calling onConstraintViolation. this 
queue is not cleared and this leads to multiple calls to the server.

My question is how/where to clear the request context of any method 
invocations that have lead to the call of onConstraintViolation 

thanks in Advance
Alex

Re: chrome - prompting me to install gwt plugin but already installed

[Xavophonic]

Hi,

Here is my configuration

Google Web Toolkit 2.0.4 on my server Jetty.
Chrome version 18.0.1025.162 m
Windows XP PS3.
Google Web Toolkit Developer Plugin version 1.0.9738.

After installed the plugin, I restart Chrome. I come back to my
development page. I still have got the message : "Development Mode

URLs to an old version of the plugin, but they are broken.

Publishing the old version of the plugin in the extention gallery
would be helpfull.

Could someone help me ?

Best regards,

Xavier

Re: Compile Gin-enabled GWT application with ant

[Sergey Stupin]

I find the answer. Modify classpath by adding your compiled GWT classes 
(that's why GWT compiler could not found it), because GIN needs class files 
to compile successfully.
 
 
  
  
  

It helps to me.

GWT applications session management

[Adio]

Hi guys, i am a new to GWT applications to AJAX applications in
general. i am making sample applications, to learn GWT applications. I
am creating a very simple bank system -ok, by very simple i mean very
very simple- and i reached the part the authentication and
authorization logic is needed.

Can someone explain the authentication logic in GWT apps ?

Anyone explain the entire authentication and authorization logic in
Ajax application ?

Session management in Ajax applications ?

If you don't want to bother yourselves with explaining and code
writing any useful links will be fine.

Thank you very mush.

Clear queue method invocations on RequestContext

[Alex Vakaloudis]

To perform a save  in a view I am using the RequestFactoryEditorDriver to 
flush any changes to a RequestContext and then I call save(the edited 
proxy).to(MyReceiver).fire();

MemberRequest s = (MemberRequest)editorDriver.flush();
MemberProxy sectorProxy = (MemberProxy)getProxy();
s.saveMember(sectorProxy).to(new MyReceiver()).fire();

MyReceiver has a onConstraintViolation method which displays violations 
generated in the server. I am using my own ServiceLayerDecorator.validate() 
to check for any business-related constraints.

To this point it works fine. However when after more than one  attempts the 
user finally "fixes" all violations and the entity reaches the service 
layer, the save method is invoked multiple times (as many attempts it took 
to pass validation). I understand that this is because the request context 
is queuing all method invocations and by calling onConstraintViolation. 
this queue is not cleared. As a result, when it passes validation there is 
a number of onvocations for saving which all then succeed in inserting to 
the database.

My question is how/where to clear the request context of any method 
invocations that have lead to the call of onConstraintViolation so the save 
to the service layer is called once only.

thanks in Advance
Alex

Here is the code i did.

Persistent Class: cls_tbl_user
package gwt_hibernate.client;

public class cls_tbl_user

private String id;
private String name;
private String address;

Problem requiring GWT app to use HTTPS

[David Robison]

I have a GWT app that has been running fine over HTTP. I now want to
restrict it to using HTTPS. I've modified the web.xml file as follows:


http://java.sun.com/dtd/web-app_2_3.dtd";>



  
guiceFilter
com.google.inject.servlet.GuiceFilter
  

  
guiceFilter
/*
  

  
com.orci.vicads.server.AppConfigListener
  

  
AlarmClips.html
  

  

securedapp
/*


CONFIDENTIAL

  



I am running inside of JBoss AS5. When JBoss tries to startup the app
I get the following error:

ERROR org.apache.catalina.core.ContainerBase.[jboss.web].
[localhost].[/ORCI-GWT-V5MilestoneAlarmClips-1.0]  Error configuring
application listener of class com.orci.vicads.server.AppConfigListener
java.lang.ClassNotFoundException:
com.orci.vicads.server.AppConfigListener

However, when I remove the security-constraint, the app starts up
normally. Am I doing something wrong?
Thanks, David

Dynamic CompositeCell

[Aoxiang Cui]

The title is too short, let me explain and simplify my situation.

Say, I have a dto which contains a list of Booleans. I need a column whose 
cell looks like below:

item_1  checkbox_1
item_2  checkbox_2
...
item_n  checkbox_n

If n is a fixed number, it is fine to use CompositeCell. The problem is we 
don't know the size of list and each cell can have different list size.
Is there any way to extend CompositeCell so as to make it support my 
situation. Or maybe I should write a new Cell?

Re: ff11 gwt dev plugin

[guy2]

Hello Alan,


Mozilla have just released FF 12.

Can you please compile the plugin for FF 12 ?

Personnally, I need the version for Win XP 32bits and Win 7 32/64 bits.

FYI, Mozilla changed at the end of 2011 (if I remember well) their policy 
about releasing FF.
Now, they release a new version every 6 weeks (FF12 has been released in 
fact 5 weeks after FF11).


Best regards,

Guy2

RequestCallback callback = new RequestCallback() {

String userIdentity = response.getText();

@Override

Please anyone kindly help me to solve this problem.
Thank you.

Re: A problem with richtextareas in Firefox 11.0

We also have the same issue with FF11 when using multiple richtextareas but 
when we try resizing the screen, the text comes back.

Does anyone have found another way around ?
Any bug report ?

Thanks in advance,

Re: GWT "The type XXX is already defined" error on package-private classes with NO previous definition.

[Darek kay]

Since I spent some time searching for a solution, here it is. Don't put top 
level classes like this:

public class1{
}

class2{
}

Although it's a valid java syntax, GWT doesn't seem to handle this very 
well. That's what it should look like:

public class1{
 static class2{
 }
}

Thoughts on User defined time in the UI

[GlasgowSteve]

I would like to have a field in my UI which allows the user to pass a
24h time - I will then use the time to do a search on events occuring
after that time. There should not be a date asociated with the time on
the UI. The time passed should be in the format "hh:mm:ss".

I'm using plain ol' GWT - extensions or addtional libraries are
unavailble here for all intents and purposes (I've seen a few options
in gwt-ext and smartGWT but would rather avoid.

What would be the best method of allowing users to define time in the
UI using core GWT? A textbox which assumes 6 digits (hhmmss) that can
then be parsed? Three seperate text boxes for hour minute second which
would be easier to validate? Extending a Calander Widgit? Another
Widgit I've overlooked that should be considered? Or something I
haven't considered at all?

Preventing selection event propagation

[ALB-PSP-DV1]

Our application has two tabs. On selecting the tabs we have to display
a confirmation window(dialog box). Depending on whether user clicks
"Yes" or "No" button in the confirmation window, the tab selection
event should proceed or stop.

I know we have event.stopPropagation() method for click event. However
there is no such method for selection event.

Is there any work around to stop the propagation of the selection
event. Any help is much appreciated.

Thanks in advance.

FlexTable.getColumnFormatter().setWidth has no effect

[tong123123]

I have set the column width as follow but the output does not follow the 
.getColumnFormatter().setWidth as attached image, for example, column 3 
should be 5% but from the attached image, column 3 (the textbox next to the

Please recommend table widget to display a number of similar widgets

[Vitaly Trifanov]

Hi everybody.

I need to display a big amount(1000+) of similar widgets (each widget
contains photo + descrption - about 400*400 px total) in a table -
say, 10 rows and 2 columns per page. I don't need option to select,
drag, highlight or do smth else with these widgets - just display
them.

It seems that FlexTable doesn't support paging. CellTable does, but it
seems to be too complicated and best suited for displaying different
data in different columns while I need just to place similar widgets
in each cell.

So, I'm a bit confused about what table to use and need some help
about this.

Thanks in advance!
