Re: Is it possible to consturct CellTree form database via rpc
updateRowData()/updateRowCount() needs to be called on the data provider, not on the cell tree. - You first create a cell tree, passing a tree model to the cell tree constructor. - The tree model will be creating node info nodes in TreeViewModel.getNodeInfo() - DefaultNodeInfo takes an instance of a data provider for its constructor - The data provider initiates an RPC call - When the data provider receives results back, it updates ITSELF, not the tree Take a look at the showcase code for more details http://gwt.google.com/samples/Showcase/Showcase.html#!CwCellTree On Jan 3, 11:30 pm, yeti superi...@gmail.com wrote: Thank you Y2i, Your messages are greatly help to me But there is an another problem stuck in... updataRowCount() and updataRowData should work with hasData, but cellTree doesnt implement it, so my requestion is, as to cellTree, how do both functions above work?

How align Cneter widget in dock layout panel
Hi All, I have created my main Panel using DockLayoutPanel where I have added MenuBar on North side and subMenu on west side and Cell table on center. Now the issue is that my cell table on default set to middle aligned (vertical) and whenever the height of the table changes then it is realigning to the middle. I have tried to set this to top alignment in CSS using vertical- align :top but no success. Please let me know how to freeze the table to the top. Thanks for your time.

deploy new server version - how to inform clients?
Hi, when I install a new server version, I redirect my URL to a under construction page beforehand. Then I undeploy the app and redeploy it. However, during this process the clients often still have the old app in their browsers. When the new app is deployed they may receive incompatible errors. When the new app is still not deployed, they receive not available errors. In both cases, a browser reload will help, either by serving the new app or by serving the under construction page. My problem is that even if I do the redirect, the clients do not see the under construction page, because the app is still in the browsers and struggles with errors. Is there a mechanism, so that the apps in the browsers inform the user that a reload is required when a) the app is not available or b) the server's app is newer than the browser's version? Or how do you deal with this problem? Thanks Magnus -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

How to style check boxes, radio buttons etc. with GWT?
Hello everyone. I have the following question: We are looking to change the look of the check boxes, radio buttons and combo boxes on our site, similar to this solution: http://ryanfait.com/resources/custom-checkboxes-and-radio-buttons/ This is of course not possible with pure CSS - meaning Javascript or any kind of other crude or advanced programming language always has to be employed. So I wanted to know, it there a way to implement this over GWT? Is there a GWT widget or widget library or maybe even custom widget that would support making styled check boxes, radio buttons and combo boxes? Additional info: I'm a designer working together with a programmer on a website and I have been charged with everything concerning the visuals of the site. Even though I have HTML, CSS and PHP skills, my Java skills are really very limited to non existent. We are using GWT with Eclipse. Actions so far: - Search on the internet I found that Smart GWT supports check boxes and combo boxes, but not radio buttons, and it is not at this time an option to purchase a Smart GWT license, so this is not a solution. I hope that this question has not been posted before. I will continue my search on the net, looking for answers, but I'm somewhat at a loss here... -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: How to write file with GWT?
Hi again,
GAE don't allow to use FileWriter, but I need to write an XML file!
I noticed it from here:

.
that allow writing to an XML file

AsyncCallback callback = new AsyncCallback()

System.out.println((String)result);
}

I think that's not a compiler option, but an option for the GWT Hosted mode. I don't think you have to do anything special to the compiler to run it with your Websphere server. -noserver just means that the GWT Hosted Mode should not start up its embedded Jetty server.

Re: GWT 2.1 compiler option : -noserver
The documentation page that you mentioned has -noserver under Development Mode Options. If you want to debug your project using a Websphere server as backend, you probably don't want to run the compiler but the Development Mode anyway? -startupUrl is also a Development mode option. I think you need to use com.google.gwt.dev.HostedMode instead of com.google.gwt.dev.Compiler.

Re: Upgrade to GWT 2.1.1
Tks Chris,
I believed that this was the problem (although I disabled the Roo from my
project). But I found that the problem is actually with the Maven GWT
version. Once Maven is referencing a GWT 2.1 jar file, the errors I'm
getting are due to the incompatibility with the GWT defined in my project
(which I changed to 2.1.1). I renamed my GWT 2.1.1 jar files to be placed as
Maven 2.1 and it worked, but I saw somewhere that ROO is about to release
Roo 1.1.1 (Jan - 7th) and I assume the STS will be updated as well, so I'll
keep working with the 2.1 for now until Roo is also updated.
Thanks,
Aldo

Aldo,
If this is a Roo-generated app, you'll need to wait to until Roo 1.1.1 is
released to upgrade to GWT 2.1.1. For now Roo-generated apps are only
compatible with GWT 2.1.

Hi All,
I'm using STS 2.5.1 (i.e. Eclipse 3.6) and tried to upgrade to GWT 2.1.1,

project reference to use them and compile the project. It all worked fine,

Does anybody has any idea of what I'm doing wrong here?

Re: org.eclipse.jdt.internal.core.JavaModel cannot be cast to org.eclipse.jdt.core.IJavaProject
I have some more information on this problem. I only get this error if my workspace in eclipse is named the same as my GWT project. In other words, if I create a new GWT project and use the same name for the project as the name I used for my eclipse workspace, I get the unable to cast error. However, if I create a new GWT project with a name that is different than the workspace name then everything works fine. This means of course that any existing projects where the workspace and the project name are the same will get this casting error. Could anyone comment on this? Is it standard practice to keep the workspace and project names different?

Dependant style not applied
I'm trying to apply a dependant style to an InlineLabel, and I can see
that the correct style is being set in firebug (since chrome is still
broken ...), but the style isn't actually being used. Here's the
code:
*.ui.xml --
ui:style ../../resources/definitions.css
@external mainNavLink-selected mainNavLink-disabled;
.mainNavLink {
font-size: 16px;
margin-left: 25px;
}
.mainNavLink:hover {
color: COLOR_SIX;
cursor: pointer;
}
.mainNavLink-selected {
color: COLOR_SIX;
}
/ui:style
--- in the presenter ---
selectedLabel.addStyleDependentName(selected);
--- in firebug HTML
span class=EO-agt-fathom-ifathom-client-view-take2-
ContentView_ContentViewUiBinderImpl_GenCss_style-mainNavLink EO-agt-
fathom-ifathom-client-view-take2-
ContentView_ContentViewUiBinderImpl_GenCss_style-mainNavLink-
selected
--- in firebug Style tab ---
.EO-agt-fathom-ifathom-client-view-take2-
ContentView_ContentViewUiBinderImpl_GenCss_style-mainNavLink {
font-size: 16px;
margin-left: 25px;
}
So you can see where my dependent style has actually been applied to
the InlineLabel in the html, but for some reason it's not actually
using it. Does anyone have any insight to why this is happening? Any
thoughts would be appreciated
Thanks,
John

Creating a Client-Only GWT Project in Eclipse
Basically, I would like to start by clicking Eclipse's New Web Application Project button (which creates a standard client/server example project). Then, I want to remove everything that relates to using a server. Though I know I can just copy the JS and other files to another machine for deployment, it seems that extra space and execution time is needed during devlopment even though I don't need server support. So, can someone (please!) provide a list of all files that can be deleted as well as any config file (e.g., web.xml) changes that need to be made to transform the standard GWT project into a client-only version?

GWT Image Bundles - Only for Small Images?
I am creating an application that will display one of about 20 PNG images upon selection of a corresponding tree item. Each image is on the order of 200K in length. Would it make sense to use GWT's image bundles for this? Or, are bundles designed to be used more with a collection of much smaller files (e.g., icons). I would guess there is some maximum data transfer size limit over which bundles would incur too long of a start up time.

Defining ChangeHandler in a Hidden Widget
Hello all,
I´m triying to define a ChangeHandler in a Hidden widget wrapped from
the html file. The code used to achieve this is the following:
input = Hidden.wrap( DOM.getElementById(input));
ChangeHandler handler = new ChangeHandler() {
@Override
public void onChange(ChangeEvent event) {
// TODO Auto-generated method stub
//The logic
}
};
input.addHandler(handler, new GwtEvent.TypeChangeHandler());
Then clicking on a button, the Hidden widget value is changed, but it
seems that the change event is not being captured.
Is the event handler implementation wrong? Or I´m forgetting
something?
Thanks in advance for your help,
Kevin.

Persist/remove methods in ServiceLayer
Hi,
I have a question is it passible to make RequestFactory work with service on
server side which have persit/remove for entities.
In other works i have
on server side:
public interface PlanetService {
public long countAll();
public void delete(Planet entity);
public ListPlanet findAll();
public ListPlanet findEntries(Integer firstResult, Integer lastResult);
public Planet save(Planet entity);
}
client:
@Service(value = PlanetService.class, locator = PlanertServiceLocator.class)
public interface PlanetRequest extends RequestContext {
RequestLong countAll();
RequestVoid delete(PlanetProxy planetProxy);
RequestListPlanetProxy findAll();
RequestListPlanetProxy findEntries(Integer firstResult,
Integer maxResults);
RequestPlanetProxy save(PlanetProxy planetProxy);
}
Everything expect save/delete work fine.
Client is roo like app + few changes for locators.

Re: GWT Image Bundles - Only for Small Images?
The answer to your question may depend on how you use your images, but others may have stronger opinions. Either way, if you're using large png images, you should beware this issue: http://code.google.com/p/google-web-toolkit/issues/detail?id=5651 HTH Paul On 04/01/11 15:08, khj wrote: I am creating an application that will display one of about 20 PNG images upon selection of a corresponding tree item. Each image is on the order of 200K in length. Would it make sense to use GWT's image bundles for this? Or, are bundles designed to be used more with a collection of much smaller files (e.g., icons). I would guess there is some maximum data transfer size limit over which bundles would incur too long of a start up time.

Re: GWT 2.1 compiler option : -noserver
Make sure you have a gwt.codesvr query parameter on the URL. Otherwise your development mode server won't be used. Then, as long as you have a debugger attached to your development mode process, you should be able to debug client side code. Note that any RPC calls will be handled by server that the app is deployed to. When not using -noserver, this would be the Jetty instance started by development mode. In your case, it'll be your Websphere server. You'll have to attach a debugger to that to debug anything on the server. -Brian On Tue, Jan 4, 2011 at 9:52 AM, Srividhya Ramachandran svr...@gmail.com wrote: I tried the -noserver option with devmode and changing the startupURL, but the debugger does not break at the breakpoint (the appln runs fine).

Re: What does this message means - Error in Generated.....FieldSerializer.java
For every that GWT translates to javascript for use in the client, you must tell GWT where the source code is so that it knows how to translate it. The error message is telling you that mypackage.database.MyClass is in a directory (mypackage/database) that is not amongst the directories that you have told GWT contain translatable source code. However, MyClass is being used from client code, and so GWT wants to translate it. If you want MyClass to be used in the client, then your gwt.xml file needs to specify that its directory (or a parent directory) contains source code.

Re: SelectionCell is displaying empty combo box
Perhaps you just snipped out the code, but in the bit you posted here
I don't see anything adding any strings to the picUps ArrayList. The
selection cell uses that array to build its options, so if that
collection is empty, then that would explain your empty combo box
issue.

Re: GWT with JPA located in a separate project
Thanks, paxdei! It looks like I'm missing a step. I've added the gwt.xml file in the core project, and added an inherit into the GWT project, but I still get errors on the inherit. Is there something else I need to do? Do I need to: * Add a gwt compile step in the core project? * Add the core jar to the GWT project? I'm missing the step which links the two projects together.

RequestFactory cast problem with polymorphic objects
Hi,
that is my situation:
I've got a base class
...
public class Recipe {
...
public static ListRecipe findAllRecipes()
}
and some child classes
...
public class Appetizer extends Recipe {
...
}
...
I managed to store different recipe objects (Appetizer, Deserts etc)
in the datastore.
When I call findAllRecipes() through the requestFactory i expect
only objects that are derived from the class recipe. But all returned
objects are of class recipe and i can't distinguish them. When I list
the classnames of the fetched objects on the server-side I see the
correct classenames for the objects.
I works find in my server-side unit tests but not with the
requestFactory.
Is this a bug or am i doing something wrong.
Thanks for any help...

Re: how to avoid instanceof checks in ActivityMapper ? is DoubleDispatch used in Expenses sample ?
I was thinking of a similar approach, but couldn't come up with a way to populate the lookup table (initialize it for the first time with data). could you please explain how you register activities/places in the lookup table, so that they are available at run-time ? At the moment I simply populate a hash table with factories in a static constructor. what is the best way to deal with scenario above in GWT MVP ? should Activities/Places mimic structure of entity they are related to ? (forming parallel object hierarchies ? for place/activity/proxy ) I'm not sure what is the best way, I personally use the second approach. While my Entity graph is complex and has cycles, my places extend from a common EntityPlace and the hierarchy is flat and one level only. At the top level I have one place controller, one activity manager, one place history mapper, one activity mapper, and one display area. At the top of the screen I have a CellBrowser that allows a user navigate deep down the object hierarchy, and every time a client clicks on some node, a new activity starts and displays a corresponding view. CellBrowser helped me to deal with the lack of support for nested activities/viewers. Activities that are created when a user clicks on a CellBrowser are complex. They themselves create NestedActivityManager (my implementation that is similar to GWT ActivityManager, except it replaces onPlaceChange(Place) with startActivity(Activity)) to by-pass places and manage nested activities directly. This level, as the top level, also uses MVP, but there is no integration with history tokens and places here. -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

It's not a bug, it's the way RF works (for now): there's no polymorphism on the client-side, you get objects of the exact type declared in your service stub or proxy (EntityProxy/ValueProxy) interfaces.

Re: RequestFactory cast problem with polymorphic objects
Thanks for pointing to this issue Thomas! A follow up question: how do we distinguish between the sub-classes on the client? JPA queries are polymorphic, so on the server the sub-classes are distinguishable. For single table and joint inheritance strategy JPA internally uses a discriminator column. The discriminator column could be used to distinguish between sub-classes, but the problem is it is not accessible even on the server side. Thanks a lot for your help!

Sebe If you want to use GAE (or really any other kind of server) for this solution, you should learn about database entities. GAE won't let you write files. Other web app servers will, but anyway, writing a file each time the user clicks on your form is a very, very, very bad idea! I don't really have the time to explain why I think its such a bad idea, but, really, it is. I've developed a large number of web applications on different platforms in both Java and PHP, including a large music aggregation site and number of user created content sites and learning about how databases work is a key requirement for any modern web programmer. I'm trying to say this as simply as possible - GAE is a platform which already has mechanisms to do what you want to do. It provides a persistent store using two mechanisms, JDO and JPA, which are meant for exactly the kind of application you have in mind. Please read about these and work through the examples. As a very brief introduction, to store and retrieve your data you could create an 'entity' which contains the information the user provides. That entity can be a simple POJO, with just a few getters and setters. Then you can map that to the database and all the work will be done for you. If you need to make that entity available as an XML file then you can create a Restful service that will do it for you. Good luck!

Re: Write document in Server-side

That entity can be a simple POJO, with just a few getters and setters. Then you can map that to the database and all the work will be done for you. If you need to make that entity available as an XML file then you can create a Restful service that will do it for you. Good luck!

Re: Runtime errors after updating to 2.1.1
The remaining references to 2.1.0 were in my project's Properties Java
Build Path Libraries. I install GWT SDK into Eclipse for the Google
Plugin and then do Maven builds with GWT as Maven dependencies. I
don't like the redundancy but I don't know how to make the plugin work
without the SDK. When I removed the 2.1.0 libraries from the build
path the error was cleared. I expected updating the SDK would have
cleaned this up. Shouldn't it?
Fábio, thanks for prompting me to double check.

Re: problem migrating to 2.1 application hags
This certainly seems to be a compiler bug that was introduced in 2.1.1
I tracked this down by brute force using alerts. I turned out to be a
simple
for loop that worked fine in GWT 2.0.2. I added the following
if (filters[i].getReportColumns() != null) {
for (int j = 0; j filters[i].getReportColumns().length; j++)
{
do some work here
}
else {
Window.alert(testing COLUMNS = NULL);
}
The alert is never triggered but now the code works fine!!!
All I did was put a null check around the for loop and the generated
code works fine.
Now I am seeing nother 2.1. problem with popup panels and date
pickers. Again
this code worked fine in 2.0.2 and now when I try to select a date via
a date picker
in a popup panel GWT throws the following error:
Uncaught com.google.gwt.event.shared.UmbrellaException: One or more
exceptions caught, see full set in UmbrellaException#getCauses
This fails in both the latest versions of Fire Fox and Chrome but
seems to work in devmode
Once again this code worked fine in GWT 2.0.2
Is anyone else seeing new compiler bugs introduced in GWT 2.1?

Re: GWT with JPA located in a separate project
The core objects need to be GWT-compiled along with and at the same time as the rest of the GWT application. Therefore the source needs to be available to the GWT compiler. From what I've heard, you should be able to package the source files (and the .gwt.xml file) in the core jar and the compiler can find them there, but I haven't tried it myself. Then, yes, the core jar does have to be added to the GWT project. The core project does not need a separate GWT-compile step. -Brian On Tue, Jan 4, 2011 at 11:55 AM, Sagadon sagadongafri...@gmail.com wrote: Thanks, paxdei! It looks like I'm missing a step.

Re: How to write file with GWT?
Yes, but that doesn't actually 'write' the file does it? It just generates a String which contains the XML representation of the java object. Its not persisted anywhere. You can generate a String representation of an object on the client with a few StringBuilder calls if you want to. I believe that OPs problem is that he wants to save it somewhere.

Encoding / decoding arrays and lists using AutoBeanCodex and more...
The new AutoBean in 2.1.1 is great. Finally, there is a decent json
tool that works in both js mode and pure JVM mode =)
The basic scenarios described in the wiki (http://code.google.com/p/
google-web-toolkit/wiki/AutoBean#AutoBeanVisitor) work fine for me.
I started poking further and I see some rooms for improvement. If
there are work arounds I missed, please let me know =)
1. arrays / lists of beans
lists as bean properties work fine. However, I couldn't find a way to
operate on a list of beans
say I have
===
interface Bean {...}
interface Factory extends AutoBeanFactory {
AutoBeanBean bean();
}
// create a bean, fill in some properties
// the only serialization code I found is:
String json = AutoBeanCodex.encode(AutoBean wrapper).getPayLoad();
// it would be nice if there is a method that does
AutoBeanCodex.encode( ListAutoBean? warppers ).getPayLoad();
which outputs json arrays of beans:
[ {bean1}, {bean2}, ... ]
One workaround I realized is to have a list interface such as
interface Beans {
void setBeans(ListBean...);
ListBean getBeans();
}
but this introduces quite a bit boiler plate stuff that could be
avoided easily
2. java.util.Date formats
The default date serialization format looks like epoch. Is there a way
to configure this?
This could be a neat feature when using AutoBean in the JSON
interoperability layer. e.g. to work with REST services that only
accept / return ISO8601 full dt formats.
It would be great if such configurations can be set as annotations
e.g.
interface bean {
@PropertyFormat(-MM-dd'T'HH:mm:SSZ) // maybe also accept
predefined formats in date time utils?
Date getDate();
// or annotate setter
void setDate(Date date);
}
and the serialized json would be something like
date:2011-01-01...
comments welcome =)

Re: Refreshing reference message and eclipse extremely slow
Hi Jerome, Sorry that we've been silent on this issue. We're looking into this problem now. I've updated the issue with a request for some information from those of you experiencing the problem. It would be helpful to us in diagnosing the problem. Regarding the release notes, we have not done a good job of updating them. We'll improve this process in the future. GPE 1.4.2, as you noticed, did not contain a fix for this specific issue. Rajeev On Thu, Dec 23, 2010 at 4:40 AM, Jerome C. jerome.ca...@gmail.com wrote: Any news about this ?

Re: client using older version of gwt
There is (as far as I am aware) no built in mechanism to handle this kind of thing. I had a discussion on this not too long ago. http://groups.google.com/group/google-web-toolkit/browse_thread/thread/94bbcb3720f83605 The general conclusion was to roll your own, if you feel as though it is worth the cost. A few examples were brought up there, with the main difference being whether you are proactive (checking with every request) or reactive (checking in the case of errors). In my case, I have decided to simply live with the possibility of outdated clients, as they are mostly benign things, and our typical deployments are during hours when users are not in the system. -Ben On Jan 4, 2:52 pm, Magnus alpineblas...@googlemail.com wrote: How can one track the version numbers?

GWT ResizeComposite resizing issue in IE
Hi All, I am developing a GWT application that consists a ResizeComposite as the main body container which is wrapped in a TabLayoutPanel. This composite widget contains two child widgets. Left widget is a GWT tree and it contains hyperlinks. The right widget is a simple panel that contains image tiles. The functionality is if user clicks on a link in the tree the corresponding tiles are loaded to right hand side widget (simple panel). However, this widget does not get resized according to the browser resize For example if I resize the browser window to half size and click one of the links in the tree. The image tiles are loaded with scrollbars in the simple panel. Then I resize the browser window and the ResizeComposite widget does not get resized according to the browser size. I tried with almost all the possible solutions but no success. I figured out that the div tag that belongs to ResizeComposite does not get the size updates but the parent div resizes properly. (I used IE developer plugin for that) I do not have any experience of using this widget before and I googled and try this groupd as well but I haven't found any good answer yet. Please help. -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group. To post to this group, send email to google-web-tool...@googlegroups.com.

UIBinder component in multiple packages
Hi.
I crawled the archives but could not find the answer to the following
question. I read the UIBinder doc too.
I would like to create a library of components created using UIBinder.
I would typically have in the
com.my.company.common
package
a
test2
component, implemented in a .java and a .ui.xml files.
This component would be used by another component
test1
defined in the
com.my.company.client
package.
Please find below this simple test project.
When I start/debug this simple case, I get a :
«
Rebinding com.mycompany.client.test1.test1UiBinder
Invoking generator
com.google.gwt.uibinder.rebind.UiBinderGenerator
Package not found : com.my.company.common
Deferred binding failed for
'com.my.company.client.test1.test1UiBinder'; expect subsequent
failures
Unable to load module entry point (...)
»
As far as I understand, the compiler has no reason to include things
from com.my.company.common, as these are not used at compile time. How
can I force it ?
Thanks in advance for your help,
Ludovic

Date/Time support on client side
Hi, let me apologize in advance for my trivial post, but I really don't know any better place to ask the question: I want to have a widget consisting of three list boxes allowing people enter their date of birth. However, it seems GWT lacks any support for working with date/time on client side. There is the old java Date class that has all methods deprecated - and that's the only positive thing I can say about it, because getYear returns some stupid number to that you have to add 1900 to get actual year, getDay returns value representing day in week value, etc. So, it isn't that hard to fill the combos with values, but such simple task like setting the actual day as selected in respective list box is impossible for me. How would you solve my issue? - I don't want to use any date picker (like the one provided by GWT) With Regards, Tom -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Removing inline styles from Layout Panels
Hello, I'm working on my first project with GWT, and trying to get my head round the DockLayoutPanel and all the absolutely positioned divs it adds to an HTML page full of inline styles. I'm working on the front-end in partnership with a Java Developer who has put together a UIBinder file with a DockLayoutPanel element and a couple of children dividing the page, however I'd like more control over the HTML created, especially as there are the inline styles in there. Can I remove these inline styles or should I revert to standard HTML? Are the LayoutPanels used for prototyping more?

Re: Date/Time support on client side
Adding/subtracting 1900 is not a big problem. Instead of setDay() use (also deprecated) setDate() Also, take a look at DateTimeFormat http://code.google.com/webtoolkit/doc/latest/DevGuideCodingBasicsFormatting.html#datetimeformat If you are concerned about using deprecated methods, you can always convert a string to a Date or to an int using various DateTimeFormat.parse(...) methods.

Re: Date/Time support on client side
Unfortunately, you are stuck with the old java.util.Date object. GWT as of yet has nothing more to offer. There is the DateTimeFormat class, which will allow you to parse bits out of the date object, and possibly construct the date object if you mash your three combo boxes into a suitable string. That might help you out a bit. I've also heard of people making server calls to do date manipulation. Its not pretty, or efficient, but it would work. You are far from the only one to mention the lack of a good calendar object. Feel better in knowing that others are suffering as well. http://code.google.com/p/google-web-toolkit/issues/detail?id=603 -Ben On Jan 4, 9:41 am, Tom Rada tom.r...@gmail.com wrote: Hi, let me apologize in advance for my trivial post, but I really don't know any better place to ask the question: I want to have a widget consisting of three list boxes allowing people enter their date of birth. However, it seems GWT lacks any support for working with date/time on client side. There is the old java Date class that has all methods deprecated - and that's the only positive thing I can say about it, because getYear returns some stupid number to that you have to add 1900 to get actual year, getDay returns value representing day in week value, etc. So, it isn't that hard to fill the combos with values, but such simple task like setting the actual day as selected in respective list box is impossible for me. How would you solve my issue? - I don't want to use any date picker (like the one provided by GWT) With Regards, Tom -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Workaround for Embedded objects
Hi, I've been struggling with RequestFactory lately and I just found that it doesn't support what I need, i.e. Embedded objects. Note that RequestFactory does not currently support embedded objects (@Embedded in various ORM frameworks) because it expects every entity to exist independently with its own ID (from http://code.google.com/intl/pt-BR/webtoolkit/doc/latest/DevGuideRequestFactory.html#relationships ). I'd like to know how I can achieve the same result as using @Embedded / @EmbeddedId. Any clue? One last information: What I need is to map a N:M relationship and add some extra data to it, so I followed these instructions: http://sieze.wordpress.com/2009/09/04/mapping-a-many-to-many-join-table-with-extra-column-using-jpa/ Thanks, Aldo -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: Workaround for Embedded objects
ValueProxy can help with @Embedded, please take a look at Thomas' post here: http://groups.google.com/group/google-web-toolkit/browse_thread/thread/743631b8460d931b/4242f0ef5de751e7?lnk=gstq=ValueProxy#4242f0ef5de751e7 On Jan 4, 3:43 pm, Aldo Neto tumo...@gmail.com wrote: Hi, I've been struggling with RequestFactory lately and I just found that it doesn't support what I need, i.e. Embedded objects.

retrieving entrypoint instance
I am a new bee starting with gwt.
I did a hello world example , I did not understand how to retrieve
the entrypoint instance to repalce content from RootPanel.
Here is the code I have
code
public class Application implements EntryPoint {
/**
* This is the entry point method.
*/
public void onModuleLoad() {
singleton=this;
RootPanel.get().add(new LoginScreen());
}
private static Application singleton;
public static Application get() {
return singleton;
}
public static void add(Widget widget){
RootPanel.get().clear();
RootPanel.get().add(widget);
}
}
/code
in the above code whihc I got from some getting started tutorial , an
instanceof entry point is saved in onModuleLoad method and a
static method which return this instance ? will this not casue
issues in multithreaded ? , please suggest me how to retrieve entry
point instance ?

Re: Workaround for Embedded objects
Yes, as of 2.1.1, you can use @Embedded with RequestFactory. The embedded type needs to extend ValueProxy instead of EntityProxy, and you'll need to use .with(embedded_field_name) when firing the request in order for RF to populate the field. I expect to have a sample up in the next week. Note that enums now work, too, as long as you declare the enum type in the proxy, which is shared between client and server. /dmc On Tue, Jan 4, 2011 at 7:16 PM, Y2i yur...@gmail.com wrote: ValueProxy can help with @Embedded, please take a look at Thomas' post here: http://groups.google.com/group/google-web-toolkit/browse_thread/thread/743631b8460d931b/4242f0ef5de751e7?lnk=gstq=ValueProxy#4242f0ef5de751e7 On Jan 4, 3:43 pm, Aldo Neto tumo...@gmail.com wrote: Hi, I've been struggling with RequestFactory lately and I just found that it doesn't support what I need, i.e. Embedded objects.

Re: retrieving entrypoint instance
Entry points are declared in *.gwt.xml module files. When a module is
loaded, every entry point class defined in the module file is
instantiated and its EntryPoint.onModuleLoad() method gets called.
An entry point is instantiated only once and onModuleLoad() is also
called once, so there is no issue in storing the entry point reference
in a static field. In addition, there is no multi-threading in GWT.
