How to remove Space between disclosure panels
Hi All, I am trying to add 2 disclosure panels to main panel (vertical panel) but the promblem is that I am gettign a space in between disclosure panels even after I set the width properly. Here is the sample code SimplePanel simPanel = new SimplePanel(); simPanel.setHeight(400px); simPanel.setWidth(1000px); DisclosurePanel disPanel1 = new DisclosurePanel(Requests); disPanel1.setContent(simPanel); DisclosurePanel disPanel2 = new DisclosurePanel(Inbox); disPanel2.setContent(simPanel); VerticalPanel vPanel = new VerticalPanel(); vPanel.add(disPanel1 ); vPanel.add(disPanel2); vPanel.setSpacing(0); I have added the above vertical panel in my DockPanel center. when I open the disclosure panels then the space is getting adjusted but whenever I close the panels I am seeing some space in between the panels. Is there anyway I can Place these panels together even in the close position. I appreciate your help.

Re: GWT 2.1.1 is here!
one of the things that is great about RequestFactory 2.1.1, is support for end-to-end testing (client to server calls), without the need to use GWTTestCase. this is very important. because GWTTestCase is very slow, I have a very powerful machine, but it is still very slow, similar to JavaEE in-container testing. However with the 2.1.1 release, there are many helper classes that facilitate testing, inside JRE, you get instant results. Isn't it wonderful ? you get to test all the way from Client to Server, Asynchronous calls, fetching data, all from JRE ! perfect for Integration/System testing. I just hope to see some documentation, and basic samples, -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: How to remove Space between disclosure panels
use DockLayoutPanel, and use your other panels within regions of DockLayoutPanel. DockLayoutPanel, can have multiple north region, multiple west, multiple east, you can have DockLayoutPanels within DockLayoutPanels. avoid using Vertical/Horizontal Panel, in favor of DockLayoutPanel/ FlowPanel/SimplePanel. Vertical/Horizontal panels uses HTMl table underneath, wich many CSS designers hate. those other panels I mentioned, produce simple divs an example of how to use DockLayoutPanel in the fashion I described can be found in GWT Mail Example: http://code.google.com/p/google-web-toolkit/source/browse/trunk/samples/mail/src/com/google/gwt/sample/mail/client/Mail.ui.xml?r=9471 -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: Serve image from blob store
Hello Ahmed, http://anansu.blogspot.com/2010/12/upload-serve-and-search-images-using.html Here's a small write-up and sources to a GWT+GAE+Eclipse project, using BlobStore to store and serve images. This is meant for learning purpose only. Also this is not the only way you can do it. There are better ways most probably. Hope this helps. Thanks, Subhro.

Re: GWT 2.1.1 RequestFactory Strange Exception
I realized I was using the 2.1 style to create my RequestFactory I came across this, while digging into code: * ServiceLayer serviceLayer = ServiceLayer.create(); * SimpleRequestProcessor processor = new SimpleRequestProcessor(serviceLayer); * EventBus eventBus = new SimpleEventBus(); * MyRequestFactory f = RequestFactoryMagic.create(MyRequestFactory.class); * f.initialize(eventBus, new InProcessRequestTransport(processor)); now I am going to experiment (in test mode) with this, see if I am correct in my guess. -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: Serve image from blob store
I believe you are using an API that is restricted on GAE. support for File/IO operations are very limited on GAE, and when using third party libraries such as Apache Commons, not all of their features is supported. check GAE WhiteList to see what is supported. Often you have to look for alternatives. What might be very easy in JRE, requires some tricks to get it to work on GAE. -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Modular rpc blues
Hello What seems to me great in GWT is that it's easy to build client code and server code that can communicate through GWT-RPC. What 's great too is that you can write modules and your webapp can use those modules. Then why is it so complicated ( is it possible ? ) to have a module with GWT-RPC code ( implementation and interfaces ) that could be used in a webapp I tried many things in eclipse I tried many things with maven ( gwt-maven-plugin : goal mergewebxml ) fails when web.xml refers to external module still no success ! I wondered if there is such a project already done Is there somewhere a jar , ready made , with GWT-RPC included that I could use as a reference ? or is hopeless ? thanks for reading , and thanks to people that have already tried to help me ( from previous posts ) Patrick -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: How do you deal with dead EvenHandlers?
Actually, because the EventHandler has a reference to the class that created it (in most cases, and it's true in your case), then as long as it is referenced by the EventBus, it won't be garbage collected, and neither will be its owner class. There's no dead event handler, only things that you no longer use but haven't destroyed, so they're still there, listening and handling events, without anyone to notice it (because your code no longer has any reference on them). You really should clean after yourself; onLoad/onUnload on widgets might be a solution; but having a real lifecycle for your classes would be best (this is where MVP shines through, e.g. the start/onCancel/onStop methods of activities) -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: Serve image from blob store
yes, u are right. Have to be careful about that on GAE. For the common-libs, i am only using the file upload apis, which seems to be allowed on GAE. Also some utils from commons-lang lib, which are compatible. Thanks, Subhro.

Re: How to remove Space between disclosure panels
Hi zix, Thanks for your quick reply. As you mentioned I have added my 2 disclosure panels in a DockLayout panel.But still I am seeing the spacing problem between the panels.What I am expecting is that whenevr I close the first disclosure panel then the second panel should occupy the remaining space.Am I missing any width setting here.

Re: GWT 2.1.1 RequestFactory Strange Exception
From the RequestFactory documentation: Four special methods are required on all entities as they are used by the RequestFactory servlet: A no-arg constructor. This may be the implicit default constructor. 1. id_type getId() -- IDs can be String or Long 2. static entity_type findEntity(id_type id) 3. Integer getVersion() You could argue that this means that you cannot easily make a separate service and I believe you would be right. The only way to do this, I believe, is to create a Locator for each proxy. I asked the same question a couple of days ago.

Re: GWT 2.1.1 , HelloMVP (Google provided example illustrating Activities Places) : Compile error. Stacktrace enclosed.
Classes referenced from annotations have to be compiled for GWT to be able to process them from within generators (as is the case for @WithTokenizers on a PlaceHistoryMapper). GWT can work from *.java files only for everything else (AFAICT) but classes referenced from annotations. So, you just have to javac all your *.java to *.class (actually, only the HellowPlace and GoodbyePlace here, but by compiling everything you're sure you don't miss anything when you add a class or change an annotation's value) and put them in the classpath for Compile. -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: How to remove Space between disclosure panels
VerticalPanel are hardly necessary. Most of the time, a FlowPanel would work seamlessly. Give it a try (with no guarantee though, you'd have to first understand what this gap comes from, using browser developer tools such as Firebug or Web Inspector). -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

rest / json command pattern implementation project
Hi, in many projects large scale GWT apps the command pattern comes in handy. It provides a central point for chaching, batching, retrying of flaky connections - and also functionality for undo operations. Great :) But what about Command pattern for REST interfaces (possibly using JSON)? There are some excellent options such as resy-gwt. But as client side developer I am still used to my plain old command pattern. I am not sure if anybody is interested, but I released an alpha version of my rest (json) command pattern at google code. It is fully functional, completed with testcases and can be built out of the box using maven. Any feedback would be appreciated :) Thanks, Cheers, Raphael -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: AbstractCell, is it possible to put ScrollPanel into cell?

You cannot embed the ScrollPanel widget in a Cell, but you can wrap the

Alternatively, you could use a multiple select box instead of checkboxes.
It wouldn't include checkboxes, but it allows multiple selection.

Junk characters in response payload
Hi All, I have 2 webapps, webapp1 gets the request but the gwt rpc service is on webapp2, for this I have overridden the loadSerializationPolicy of the RemoteServiceServlet and pointed it to correct .gwt.rpc file, but the request fails and lands into onFailure method. I am pasting request payload below incase if required. I don't know what these numbers are, I think the response should only contain the object to be passed. //OK[163,2,-19,162,2,-17,162,2,-15,162,2,-13,161,2,-11,162,2,-9,161,2,-7,7,1,160,2,-19,159,2,-17,159,2,-15,159,2,-13,158,2,-11,159,2,-9,158,2,-7,7,1,157,2,-19,156,2,-17,156,2,-15,156,2,-13,155,2,-11,156,2,-9,155,2,-7,7,1,154,2,-19,153,2,-17,153,2,-15,153,2,-13,152,2,-11,153,2,-9,152,2,-7,7,1,151,2,-19,150,2,-17,150,2,-15,150,2,-13,149,2,-11,150,2,-9,149,2,-7,7,1,148,2,-19,147,2,-17,147,2,-15,147,2,-13,146,2,-11,147,2,-9,146,2,-7,7,1,145,2,-19,144,2,-17,144,2,-15,144,2,-13,143,2,-11,144,2,-9,143,2,-7,7,1,142,2,-19,141,2,-17,141,2,-15,141,2,-13,140,2,-11,141,2,-9,140,2,-7,7,1,139,2,-19,138,2,-17,138,2,-15,138,2,-13,137,2,-11,138,2,-9,137,2,-7,7,1,136,2,-19,135,2,-17,135,2,-15,135,2,-13,134,2,-11,135,2,-9,134,2,-7,7,1,133,2,-19,132,2,-17,132,2,-15,132,2,-13,131,2,-11,132,2,-9,131,2,-7,7,1,130,2,-19,129,2,-17,129,2,-15,129,2,-13,128,2,-11,129,2,-9,128,2,-7,7,1,127,2,-19,126,2,-17,126,2,-15,126,2,-13,125,2,-11,126,2,-9,125,2,-7,7,1,124,2,-19,123,2,-17,123,2,-15,123,2,-13,122,2,-11,123,2,-9,122,2,-7,7,1,121,2,-19,120,2,-17,120,2,-15,120,2,-13,119,2,-11,120,2,-9,119,2,-7,7,1,118,2,-19,117,2,-17,117,2,-15,117,2,-13,116,2,-11,117,2,-9,116,2,-7,7,1,115,2,-19,114,2,-17,114,2,-15,114,2,-13,113,2,-11,114,2,-9,113,2,-7,7,1,112,2,-19,111,2,-17,111,2,-15,111,2,-13,110,2,-11,111,2,-9,110,2,-7,7,1,109,2,-19,108,2,-17,108,2,-15,108,2,-13,107,2,-11,108,2,-9,107,2,-7,7,1,106,2,-19,105,2,-17,105,2,-15,105,2,-13,104,2,-11,105,2,-9,104,2,-7,7,1,103,2,-19,102,2,-17,102,2,-15,102,2,-13,101,2,-11,102,2,-9,101,2,-7,7,1,100,2,-19,99,2,-17,99,2,-15,99,2,-13,98,2,-11,99,2,-9,98,2,-7,7,1,97,2,-19,96,2,-17,96,2,-15,96,2,-13,95,2,-11,96,2,-9,95,2,-7,7,1,94,2,-19,93,2,-17,93,2,-15,93,2,-13,92,2,-11,93,2,-9,92,2,-7,7,1,91,2,-19,90,2,-17,90,2,-15,90,2,-13,89,2,-11,90,2,-9,89,2,-7,7,1,88,2,-19,87,2,-17,87,2,-15,87,2,-13,86,2,-11,87,2,-9,86,2,-7,7,1,85,2,-19,84,2,-17,84,2,-15,84,2,-13,83,2,-11,84,2,-9,83,2,-7,7,1,82,2,-19,81,2,-17,81,2,-15,81,2,-13,80,2,-11,81,2,-9,80,2,-7,7,1,79,2,-19,78,2,-17,78,2,-15,78,2,-13,77,2,-11,78,2,-9,77,2,-7,7,1,76,2,-19,75,2,-17,75,2,-15,75,2,-13,74,2,-11,75,2,-9,74,2,-7,7,1,73,2,-19,72,2,-17,72,2,-15,72,2,-13,71,2,-11,72,2,-9,71,2,-7,7,1,70,2,-19,69,2,-17,69,2,-15,69,2,-13,68,2,-11,69,2,-9,68,2,-7,7,1,67,2,-19,66,2,-17,66,2,-15,66,2,-13,65,2,-11,66,2,-9,65,2,-7,7,1,64,2,-19,63,2,-17,63,2,-15,63,2,-13,62,2,-11,63,2,-9,62,2,-7,7,1,61,2,-19,60,2,-17,60,2,-15,60,2,-13,59,2,-11,60,2,-9,59,2,-7,7,1,58,2,-19,57,2,-17,57,2,-15,57,2,-13,56,2,-11,57,2,-9,56,2,-7,7,1,55,2,-19,54,2,-17,54,2,-15,54,2,-13,53,2,-11,54,2,-9,53,2,-7,7,1,52,2,-19,51,2,-17,51,2,-15,51,2,-13,50,2,-11,51,2,-9,50,2,-7,7,1,49,2,-19,48,2,-17,48,2,-15,48,2,-13,47,2,-11,48,2,-9,47,2,-7,7,1,46,2,-19,45,2,-17,45,2,-15,45,2,-13,44,2,-11,45,2,-9,44,2,-7,7,1,43,2,-19,42,2,-17,42,2,-15,42,2,-13,41,2,-11,42,2,-9,41,2,-7,7,1,40,2,-19,39,2,-17,39,2,-15,39,2,-13,38,2,-11,39,2,-9,38,2,-7,7,1,37,2,-19,36,2,-17,36,2,-15,36,2,-13,35,2,-11,36,2,-9,35,2,-7,7,1,34,2,-19,33,2,-17,33,2,-15,33,2,-13,32,2,-11,33,2,-9,32,2,-7,7,1,31,2,-19,30,2,-17,30,2,-15,30,2,-13,29,2,-11,30,2,-9,29,2,-7,7,1,28,2,-19,27,2,-17,27,2,-15,27,2,-13,26,2,-11,27,2,-9,26,2,-7,7,1,25,2,-19,24,2,-17,24,2,-15,24,2,-13,23,2,-11,24,2,-9,23,2,-7,7,1,22,2,-19,21,2,-17,21,2,-15,21,2,-13,20,2,-11,21,2,-9,20,2,-7,7,1,19,2,-19,18,2,-17,18,2,-15,18,2,-13,17,2,-11,18,2,-9,17,2,-7,7,1,16,2,15,2,10,2,14,2,10,2,13,2,10,2,12,2,8,2,11,2,10,2,9,2,8,2,7,2,7,1,50,6,5,2,4,2,3,2,2,1,[java.util.HashMap/962170901,java.lang.String/2004016611,msg,success,payload,java.util.ArrayList/3821976829,categoryName,Category Name:1,parentId,Category Type 1,websiteAccess,description,categoryType,parentType,productCategoryId,Product Category Id 1,Category Name:2,Category Type 2,Product Category Id 2,Category Name:3,Category Type 3,Product Category Id 3,Category Name:4,Category Type 4,Product Category Id 4,Category Name:5,Category Type 5,Product Category Id 5,Category Name:6,Category Type 6,Product Category Id 6,Category Name:7,Category Type 7,Product Category Id 7,Category Name:8,Category Type 8,Product Category Id 8,Category Name:9,Category Type 9,Product Category Id 9,Category Name:10,Category Type 10,Product Category Id 10,Category Name:11,Category Type 11,Product Category Id 11,Category Name:12,Category Type 12,Product Category Id 12,Category Name:13,Category Type 13,Product Category Id 13,Category Name:14,Category Type 14,Product Category Id 14,Category Name:15,Category Type 15,Product Category Id 15,Category Name:16,Category Type 16,Product Category Id 16,Category Name:17,Category Type 17,Product Category Id

Re: How do you deal with dead EvenHandlers?
Hi Thomas, Yes, that would explain it and thank you very much for your input. About life cycle management, most of the classes in question are created anonymously as in my original example with the FluidTmpltDeletedGWTEvent.Handler. I guess I could keep a reference to the returned EventHandler in the enclosing class and prior to assignment to it check if the reference variable contains a valid reference (non null) and call removeHandler if it does. The funny thing is I hardly ever see life cycle management in JavaScript code, at least from my experience anyway, so I guess i just perpetuated a bad practice. My bad :) I started developing my latest application prior to the release of GWT's native MVP implementation. When 2.1 was released I thought about refactoring the application to use the native MVP noting that it held numerous benefits but I hesitated and still do because GWT's native MVP implementation didn't support DAOs (I am using Objectify) and it appeared to be a work in progress both in terms of the framework itself and its documentation which I regrettably think is quite bad. I also believe that sometimes applications benefit more from tight coupling of some of their components making for an all around leaner application though obviously in general loose coupling should be the overall goal. At some point I will probably bight the bullet and move to MVP but not until I sense a little more maturity in the native implementation provided by GWT and a better documentation set to go along with it. Thanks again for shedding some light on and answering my question. Jeff On Tue, Dec 21, 2010 at 4:07 AM, Thomas Broyer t.bro...@gmail.com wrote: Actually, because the EventHandler has a reference to the class that created it (in most cases, and it's true in your case), then as long as it is referenced by the EventBus, it won't be garbage collected, and neither will be its owner class. There's no dead event handler, only things that you no longer use but haven't destroyed, so they're still there, listening and handling events, without anyone to notice it (because your code no longer has any reference on them). You really should clean after yourself; onLoad/onUnload on widgets might be a solution; but having a real lifecycle for your classes would be best (this is where MVP shines through, e.g. the start/onCancel/onStop methods of activities) -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: Handling sessions in gwt multipage application
When the user logs in, store something in the HttpSession. Then, when the next page loads and your entry point is invoked, make a GWT-RPC call to check the session to see if the user is logged in and who they are. You can access the session from a GWT-RPC service implementation (subclass of AbstractRemoteServiceServlet) using: getThreadLocalRequest().getSession() You can store the user's preferred language in the session, too. As for tutorials, I don't have any in mind, but I'm sure you could find some examples by searching for GWT getThreadLocalRequest. -Brian On Mon, Dec 20, 2010 at 11:31 AM, Davor Peric davor.peric1...@gmail.com wrote: I'm new to gwt, and I need to handle sessions in the gwt multipage application I've built.

KeyFactory.keyToString() and KeyFactory.stringToKey() emulation for gwt
Is there any safe way of emulating those methods?
I looked into the implementation(sorry), and doesn't look very nice:
public static String keyToString(Key key)
{
if(!key.isComplete())
{
throw new IllegalArgumentException(Key is incomplete.);
} else
{
com.google.storage.onestore.v3.OnestoreEntity.Reference
reference = KeyTranslator.convertToPb(key);
return Base64.encodeWebSafe(reference.toByteArray(), false);
}
}
public static Key stringToKey(String encoded)
{
int modulo = encoded.length() % 4;
if(modulo != 0)
encoded = (new StringBuilder()).append(encoded).append(
.substring(modulo)).toString();
byte encodedBytes[] = encoded.getBytes();
byte decodedBytes[];
try
{
decodedBytes = Base64.decodeWebSafe(encodedBytes, 0,
encodedBytes.length);
}
catch(Base64DecoderException ex)
{
throw new IllegalArgumentException((new
StringBuilder()).append(Cannot
parse: ).append(encoded).toString(), ex);
}
com.google.storage.onestore.v3.OnestoreEntity.Reference reference =
new com.google.storage.onestore.v3.OnestoreEntity.Reference();
reference.parseFrom(decodedBytes);
return KeyTranslator.createFromPb(reference);
}
The other methods of KeyFactory are easy to emulate on gwt. It will be very
useful to have those two as well.
Thanks in advance.

Developing GWT app on both mobile and desktop browsers
I have a gwt application developed for desktop computer browsers and i need to modify it's architecture so that widgets can adapt to mobile screens. The app is using an MVC pattern (with some enhancements from the MVP pattern, like events distributed through an event bus). So i need some pointers or some articles to develop the app for mobile browsers as well (that is, small screen devices). This can be done by creating duplicate visual widgets (2 for each widget lets say... one for small, one for large screen), or maybe by dynamically loading another js gwt compiled code (i don't think this is a solution since the app is pretty large). I was thinking of adapting the app to the MVP pattern (one by one) and maybe also using UiBinder (currently i don't use it because most of the widgets load their inner data or inner widgets dynamically). Also, gwt tutorials/documentation that can help creating/modifying the architecture would be very appreciated. -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: GWT 2.1.1 and DAOs
Further investigation has revealed that SimpleRequestProcessor call's ServiceLayer#isLive() for every non-null domain object to check if it's still there. Otherwise the write operation is set to DELETE. IMO that's terrible: I don't want to do two entity manager/db lookups for every find (even if it's aggressively cached). Using DAOs, I don't even call remove() on my entities but on the DAO (and I call removeById() -- I don't have a domain object in these situations!) So providing a ServiceLayerDecorator with an overridden isLive() method (returning always true) solves this part. But I still need the findXxx method because of the check Henrik mentions (even if it's never called). I really appreciate the possibility to use DAOs and service locators in 2.1.1 -- but unfortunately it's still not usable (for me). I don't want data access methods in my domain models and I don't want unnecessary db operations! And I don't want to provide a totally redundant Locator for *every* domain model either... Is there any way to avoid the check for the findXxx methods? Sebastian -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: Handling sessions in gwt multipage application
One more possible way to accomplish this: 1. User sends login request to the server (with username and pass) 2. The server authenticates using whatever mechanism. On successful auth, it generates a token or session id (not necessarily using HttpSession) and send it back to the GWT client (most probably using GWT-RPC mechanism) 3. The UI now has a valid session id. For next set of application calls from the UI , always sends the sesssion id to the server. So for example after login,lets say u want to retrieve a list of model objects , the async call for that will have a parameter of session id along with other parameters as required by the call. This sessionid has to be validated each time before executing the actual application logic at the server. On session validation failure for any calls, the UI should be able to handle the case and logout the user if required. 4. To implement a remember me scenario, store this sesssion id in the browser cookie along with some expiration date/time. On a new request from the browser, read this cookie value and re-validate it at the server. This session id validation can also be performed by a filter on a J2EE container. http://code.google.com/p/google-web-toolkit-incubator/wiki/LoginSecurityFAQ http://groups.google.com/group/Google-Web-Toolkit/web/security-for-gwt-applications Both these links have a lot of good info about GWT security and how to implement them.

Re: UiBinder or GWT Designer
I use UiBinder and like it a lot because it allows me to do my markup using
UiBinder's HTML like XML tags which, if you like to code in HTML, is a real
benefit over coding your interface using Java. I don't but I could pass off
any one of my UiBinder xml files to a designer and they wouldn't feel like
they are looking at something foreign as it very HTML like.
In GWT 2.1 there are a few issues that developers must bear in mind when
using UiBinder. The most in your face issue is that you cannot dynamically
add widgets directly to an HTMLPanel but instead must have the HTMLPanel
include a native HTML container to which you append widgets to as
demonstrated in the following UiBinder markup:
ui:UiBinder xmlns:ui=urn:ui:com.google.gwt.uibinder
xmlns:g=urn:import:com.google.gwt.user.client.ui
xmlns:dp=urn:import:com.google.gwt.user.datepicker.client
.
.
.
g:HTMLPanel styleName={style.view}
.
.
.
g:HTMLPanel ui:field=salesTaxContainer
div id=addEditIPurchaseTaxContainer/
/g:HTMLPanel
.
.
.
/g:HTMLPanel
/ui:UiBinder
And in the following code snippet where a widget is added to the HTMLPanel :
salesTaxContainer.add(new
AddEditPurchaseTaxView(purchase),addEditIPurchaseTaxContainer);
This is a common coding pattern you will have to get used to when using
UiBinder and it is my understanding that this is being addressed in some
future release.

Re: UiBinder or GWT Designer
GWT Designer is a GUI design tool while UiBinder is an XML-based framework for specifying GWT UIs. GWT Designer can generate GWT code using Java or XML (UiBinder), so you can consider GWT Designer to be a tool for using UiBinder. It would not be appropriate to compare/ contrast them (as has already been pointed out). -Eric On Dec 20, 7:45 am, junaidp juna...@gmail.com wrote: Hi , I would like to know the difference in UiBinder and GWT Designer like which one is better if i'm using GWT Designer for my interface and not using any java code for the interface ,will i still be requiring UiBinder.

Re: UiBinder or GWT Designer
Totally agree with you comments, Jeff. I evaluated GWTDesigner because, generally speaking, I like RAD tools. However, I found it very slow to start - maybe a bug or something - but, being comparatively happy with XML, HTML and CSS I found that my workflow was smoother using UiBinder and it was much quicker to make changes and see what was happening. Also, I tend to use a lot of my own widgets and programmatically add and removed them from pages, and so the direct UiBinder approach made that easier. I stress that these are my own personal opinions and YMMV. I'm interested in other people's opinions.

Re: GWT 2.1.1 RequestFactory Strange Exception
@ProxyFor(value = Person.class, locator = PersonLocator.class) then having a PersonLocator which implements LocatorPerson would fix this for you. But in order to get your static service methods (besides just the find method), you need a ServiceLocator for your service: @Service(value = PersonService.class, locator = MyServiceLocator.class) I'm not sure if the locator for the service is necessary if it has a default constructor. We use Spring, so we have a service locator that just pulls the bean out of spring. -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: GWT 2.1 CELL TABLE
bradr brad.rydzew...@... writes:
To do this, you have to override the CellTable's default style.
Because CellTable uses a CssResource, which ultimately gets obfuscated
when you compile, you have to create your own implementation and pass
it to the CellTable in the constructor.
Here is how I did it:
Step 1) Create your own implementation of the Resource
import com.google.gwt.core.client.GWT;
import com.google.gwt.user.cellview.client.CellTable;
import com.google.gwt.user.cellview.client.CellTable.Resources;
public interface MyCellTableResources extends Resources {
public MyCellTableResources INSTANCE =
GWT.create(MyCellTableResources.class);
/**
* The styles used in this widget.
*/
@Source(CellTable.css)
CellTable.Style cellTableStyle();
}
Step 2) Copy the CellTable.css file into your project (from gwt trunk)
into the same package as your Resource implementation. Customize the
css until it meets your style needs.
Step 3) When you create an instance of the CellTable, give it your
your custom CssResource:
myTable = new
CellTableResource(Integer.MAX_VALUE,CellTableResources.INSTANCE);
Hope that helps!

RequestFactory entity proxies can't be cloned.
I posted this in gwt-contributors but I feel this might be the more appropriate group. I'm attempting to switch to using RequestFactory instead of GWT-RPC and manually creating DTOs. It's been going pretty well, except I've hit one use-case that is just a brick wall. I have a panel that is an EditorDocumentProxy which uses a RequestFactoryEditorDriver to handle the editing. One of the properties of DocumentProxy is another proxy, which I want to edit in a dialog box that shows when a button is clicked in the panel. The dialog is another Editor. The problem is that anytime something changes in this dialog, I want to flush the editor, send the current values to the server for validation, and report any errors right away. This works fine, but the dialog box has a cancel button, which should revert any changes made in the dialog box. I was able to do this before by storing the original value when it's set, and editing a clone while in the dialog box. But entity proxies can't be usefully cloned in any way that I currently see, so I'm at a loss as to how to get this behavior. Any suggestions? I'm currently on GWT 2.1.1rc1, should be upgrading to 2.1.1 soon. -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

UiBinder and event bubbling
Prior to UIBinder in gwt, I wrapped elements in a HTMPanel which basically handled all the events for its child elements. So instead of attaching an eventlistener to multiple widgets, I just attached it to the parent container and used event bubbling. Can I do this in UIBinder? I know in the backing class for the yourclass.ui.xml, you can use UiHandler to handle event delegation but is this optimal? Am I still adding multiple listeners or is GWT doing something behind the scenes and attaching only 1 event handler. -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

RPC Serialization Format
Hi, I'm looking for details (references to code are fine) about how the rpc messages are formatted. I'm doing penetration testing for a client's GWT rpc servlets but cannot access their source or discuss with their developers (black/grey box testing). Looking at an rpc request it appears to be formated the following way: #|#|#|URL|StrongHash|Class_Name|Method_Name|ARG1_Class_name| ARG1_member1|...|ARG1_memberN|ARG2_Class_Name|ARG2_member1|...| ARG2_memberN|#|#|#|#.|#|#|# The first three #'s appear to be related to the request and number of args, not %100 sure on this relation. The last set of #s I'm very confused on what they do and mean. I have the following use case that will probably result in a successful penetration test for my client. A request to method M1 sends and object with all the fields set to NULL. A request to method M2 sends the same object and some additional objects, but with all the fields set to valid values. I need to create a request to M1 with the same object sent to M2. Since M2 also has additional arguments the RPC requests are rather different and it isn't straight forward for me. Of course through a hundred hours of reading GWT source I could figure this out, but hopefully there is something simpler. I can request a copy of the class file for the class I need to serialize and send to M1, if that will allow me to make the request to M1 using GWT interfaces. -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

how to debug service calls, which do not come through
Hi, i am using the newest version of GWT. I have a service with a bunch of methods. Some work, some don't. The one, that does not work, seems simply not being called on the server side. If i put a breakpoint in the method of the service implementation on the server side, it doesn't get called. But the AsyncCallback is created on the client side. Unfortunately there is no exception or anything being thrown. Do you have any tips, how i could debug this?

CellTable: Style cells differently wihtin a column
Hi,
I have been searching through this forum and other places on the
internet to find examples of how to style cells differently within a
column - but without luck. I hope you can help me.
Here is my problem:
I have a CellTable showing a list of objects. A simplified example of
this object looks like this:
class MyQuote {
public String getQuoteName();
public String getQuoteType();
}
My problem is that I want to apply style A to the cell if quoteType is
X and apply style B to the cell if quoteType is Y. How can I do that?
I have tried by creating a custom column class (extends Column) and a
custom cell class (extends ClickableTextCell) but without luck. The
column class is aware of the MyQuote object and thereby both quoteName
and quoteType but if I apply the styling in the column class getValue
method - for example div class=AquoteName/div - the HTML gets
escaped. I have also tried to apply styling in the cells render method
but here I have only knowledge to the value being displayed, which is
quoteName, and not quoteType so I cannot determine the style class.
Regards,
Thomas.

2.1.1 fails in SimpleRequestProcessor.processInvocationMessages when nothing to invoke
Hi,
I believe I've uncovered an error in version 2.1.1 of SimpleRequestProcessor
when there are no invocations and only operations in a RequestMessage from the
client (stacktrack at end of email).
I'm checking here before creating an issue.
I am using an editor on the client to modify a property, then flushing and
firing.
So the RequestMessage from the client is:
---
{Operations=[{PropertyMap={title=150349-0 Title CHANGED},
ServerId=IjY1Zjg4ZjVlLWFlNDItNDcxYi04NGNkLWE2MWJmOGUxNzBjZCI=,
Operation=UPDATE, Version=MQ==,
TypeToken=au.projectx.gwt.request.ArticleProxy}]}
---
With the following stacktrace:
---
[#|2010-12-21T15:05:48.626+1100|SEVERE|glassfish3.0.1|com.google.gwt.requestfactory.server.RequestFactoryServlet|_ThreadID=28;_ThreadName=Thread-1;|Unexpected

at
com.google.gwt.requestfactory.server.RequestFactoryServlet.doPost(RequestFactoryServlet.java:118)
at javax.servlet.http.HttpServlet.service(HttpServlet.java:754)
---
It seems to me that either SimpleRequestProcessor.processInvocationMessages()
needs to cater for a null ListInvocationMessage or
RequestMessage.getInvocations() should return an empty list instead of a null.

Re: DockLayoutPanel and StackLayoutPanel problems in IE7
So, I spent yesterday getting it to work in IE7 with unpredictable results. Basically, I used DockPanel in my Layer 4 (from above). This morning, re-re-reading the cryptic documentation on the website, I found that I had not inherited from ResizeComposite. This was actually plainly put, but I missed it somehow. Note noted above is that all of my Layers are my classes with the various LayoutPanels in the initWidget(). Now I'm having predictable success with implementing in FF. However, I'm back to the same issue in IE7 nothing below Layer 4 will display. I'm also having to basically remove any VeritcalPanel or HorizontalPanels from the app if they use any widget w/ implemented in a div tag (like the ToggleButton) as the results are completely un- predictable.

Re: GWT 2.1.1 and DAOs
On Tuesday, December 21, 2010 1:25:18 PM UTC+1, Sebastian wrote: Further investigation has revealed that SimpleRequestProcessor call's ServiceLayer#isLive() for every non-null domain object to check if it's still there. Otherwise the write operation is set to DELETE. IMO that's terrible: I don't want to do two entity manager/db lookups for every find (even if it's aggressively cached). Using DAOs, I don't even call remove() on my entities but on the DAO (and I call removeById() -- I don't have a domain object in these situations!) So providing a ServiceLayerDecorator with an overridden isLive() method (returning always true) solves this part. But I still need the findXxx method because of the check Henrik mentions (even if it's never called). I really appreciate the possibility to use DAOs and service locators in 2.1.1 -- but unfortunately it's still not usable (for me). I don't want data access methods in my domain models and I don't want unnecessary db operations! And I don't want to provide a totally redundant Locator for *every* domain model either... Is there any way to avoid the check for the findXxx methods? If you really want it, yes: override all the resolveXxx on a ServiceLayerDecorator to totally by-pass the stock ResolverServiceLayer (which calls the RequestFactoryInterfaceValidator).

Re: Plugin fails to connect to hosted mode server
There isn't any. In the development mode, I dont see anything in red. In the console of the started application there is nothing printed either. This is while running the sample project. I have another project that I had developed which suffers from the same problem. This project works fine on the PC that is running XP (32 bit). But when I move to the 64 bit win 7 machine, the server starts up (i have a start up servlet that inialises stuff and logs to the console). But when I go to the browser and try to connect, it throws the failed to connect to the hosted mode error. Actually, it fails to connect to any of the other servlets I had written as well.

Re: Plugin fails to connect to hosted mode server
Hmm... Have you checked that port (if that's what you are using) is blocked in the Windows firewall? The times I've seen this there has been a networking problem such that the client can't reach the server. That would explain why it works on one m/c and not the other. I think the 32 bit vs 64 bit is a red herring - I use Win 7 X64 with a 64 bit JVM all the time and have no problems. HTH Alan On 12/21/2010 8:37 AM, Sethu wrote: There isn't any.

Re: Trying to split deserialization process after RPC call
Thank you for your advices.
I think I will linearize the tree as a List by replacing the strong
reference link between an Option and its childs to a String meaning the id
(the id is an attribute) of the child options.
Then, I will serialize the option list to a json String with flexjson and
send it to the client over GWT-RPC.
On the client, I think that the json String deserialization will be done
quickly ; I've seen on StreamReader source code that the String
deserialisation does not lead to a lot of compute time because the HTTP
response is String itself. Then, I will deserialize this json String with
the eval() method, and I will try to map it to my Option type with a
JavaScript Overlay Types.
And, if there is a need to split deserialization into multiple deferred
command, I will split my json String into multiple json string before
evaluating this with eval(), and do the eval() on each sub-sequence json
string in a deferred command. Even if this split is not simple...
What do you think about this solution ?
2010/12/20 David Chandler drfibona...@google.com
Following up on George's post, here's the DeRPC doc. You can find a
little additional info by searching for DeRPC on the public issue
tracker. DeRPC was created to help with large object graph
serialization; however, DeRPC (NOT GWT-RPC) will likely be deprecated
eventually in favor of RequestFactory.

Hi,
In a few words, I've got a problem with big object deserialization after
an

On Internet Explorer, the browser ask me to interrupt the script because
the
deserialization process is too long.
In fact, my RPC service returns a deep recursive tree, and some other
data,
where the Item is called Option :
The generated FieldSerializer looks like :
public static void
deserialize(com.google.gwt.user.client.rpc.SerializationStreamReader
streamReader, Option instance) throws
com.google.gwt.user.client.rpc.SerializationException{

}
In my mind, the invocation of setChildren() involves that the childs
Options
are deserialized too. And, because of my tree is too deep, this
deserialization process leeds to have a Would you like to interrupt the
script ? in IE6/7.
I think I could resolve this problem by adding a deferred command in this
process :
public static void
deserialize(com.google.gwt.user.client.rpc.SerializationStreamReader
streamReader, Option instance) throws
com.google.gwt.user.client.rpc.SerializationException{
//The childs of this Option node, defining the tree

streamReader.readObject());
}
}
DeferredCommand.addPause();
DeferredCommand.addCommand(c);
//Some other atomic data
(...)
}
But, to do that, I have to modify the generator of this serializer, and
i've
not found where I can do that. So my questions are :
Is it a good idea ?
How can I modify /implement my own serializer generator for this tree ?
P.S. : Furthermore, I will have to deal with asynchronism because of my
deserialize method will returns before my tree will be totaly
deserialized ;
but I will work on this in a second step.
Thank you.

Re: Plugin fails to connect to hosted mode server
Following my previous comment - you can easily check by using a windows command prompt and telnet , e.g. telnet 127.0.0.1 if the firewall is blocking it, you'll get a 'can't connect to server' error, otherwise the screen will go blank and you'll get a weird prompt (the gwt rpc connection doesn't print any kind of message.)

I need to create a request to M1 with the same object sent to M2. Since M2 also has additional arguments the RPC requests are rather different and it isn't straight forward for me. Of course through a hundred hours of reading GWT source I could figure this out, but hopefully there is something simpler. I can request a copy of the class file for the class I need to serialize and send to M1, if that will allow me to make the request to M1 using GWT interfaces. -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Sorry for jumping in, but you could use:

everything in your method.

}
The complier should then ignore everything inside the conditional.
However, it seems a bit of a kludge to exclude the whole method. Another option is sub-classing and
have a server-side version which is a sub-class of your shared class - I've done that before and

Wow Damien - I like it. Thanks for the tips.

Thank you for your advices.
I think I will linearize the tree as a List by replacing the strong
reference link between an Option and its childs to a String meaning the id
(the id is an attribute) of the child options.
Then, I will serialize the option list to a json String with flexjson and
send it to the client over GWT-RPC.
On the client, I think that the json String deserialization will be done
quickly ; I've seen on StreamReader source code that the String
deserialisation does not lead to a lot of compute time because the HTTP
response is String itself. Then, I will deserialize this json String with
the eval() method, and I will try to map it to my Option type with a
JavaScript Overlay Types.
And, if there is a need to split deserialization into multiple deferred
command, I will split my json String into multiple json string before
evaluating this with eval(), and do the eval() on each sub-sequence json
string in a deferred command. Even if this split is not simple...
What do you think about this solution ?

Following up on George's post, here's the DeRPC doc. You can find a
little additional info by searching for DeRPC on the public issue
tracker. DeRPC was created to help with large object graph
serialization; however, DeRPC (NOT GWT-RPC) will likely be deprecated
eventually in favor of RequestFactory.

Hi,
In a few words, I've got a problem with big object deserialization after

On Internet Explorer, the browser ask me to interrupt the script because

In fact, my RPC service returns a deep recursive tree, and some other
data,
where the Item is called Option :
The generated FieldSerializer looks like :

In my mind, the invocation of setChildren() involves that the childs

are deserialized too. And, because of my tree is too deep, this
deserialization process leeds to have a Would you like to interrupt the

I think I could resolve this problem by adding a deferred command in

But, to do that, I have to modify the generator of this serializer, and
i've
not found where I can do that. So my questions are :
Is it a good idea ?
How can I modify /implement my own serializer generator for this tree ?
P.S. : Furthermore, I will have to deal with asynchronism because of my
deserialize method will returns before my tree will be totaly
deserialized ;
but I will work on this in a second step.

Re: Is there a way to get have GWT not compile a method into JS?
The GWT compiler performs dead code elimination, so if you never call the
code from the client, it will not be compiled into javascript. You can
create your own annotation if you want to annotate the method so other
people on your team know not to use it.
If you want the API to be technically correct, you could create a common
base class in your shared package and subclass it in your client and/or
server packages.
com.myapp.shared.CommonUtils
com.myapp.client.CommonClientUtils extends CommonUtils
com.myapp.server.CommonServerUtils extends CommonUtils

Re: RequestFactory entity proxies can't be cloned.
IIUC, you should use 2 distinct RequestContext, creating a new RequestContext each time you open the dialog box. That way, when the use clicks cancel, you simply let the RequestContext be garbage collected, and any changes made to the object being scoped to a RequestContext would go away with it. And of course, to make sure your object isn't already edited by your main editor (which would cause a crossing streams error if you try to edit it again in another RequestContext), if you display it here, make sure you annotate the editor with @Ignore and use a specific EditorDriver for the sub-editor where you'd do a display() instead of edit(). -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: De-selecting a CellTable or CellView
The logic changed slightly from 2.1.0 to 2.1.1 to try to make it respond more naturally to use input, but there are a lot of special use cases. Just to make sure I understand correctly, this only happens when the KeyboardSelectionPolicy is set to BOUND_TO_SELECTION and you remove the selected item? If you replace the data, but include the originally selected item, it should remain selected. It makes sense that if the selected item is lost, we should not reselect a new item.

We use Spring, so we have a service locator that just pulls the bean out of spring. I am planning to use it with Spring too. in your case (spring), you need all 4 attributes ? on PersonProxy we use @ProxyFor(EntityObject, EntityLocator) on PersonService we use @Service(ServiceObject, ServiceObjectLocator) so the EntityLocator is the DAO ? and ServiceLocator queries spring context to find the Service method to handle the EntityLocator ? yet, all of these methods have to be static ?

Re: Is there a way to get have GWT not compile a method into JS?
Then you have to go the 'subclass' route - create a common (shared) interface and have
implementations for server and client
You can superclass the common parts into a 'shared' (probably abstract) class. Solves the service
side import issues.
I've done that several times and it works just fine. It may even simplify your

Yes. I agree it will be optimized out but the problem is I need to use
a class thats only on the server. So the compiler says the class is
not in a module.

Sorry for jumping in, but you could use:
public void yourMethod(...) {
if (!GWT.isClient()) {
everything in your method.
}
}
The complier should then ignore everything inside the conditional.
However, it seems a bit of a kludge to exclude the whole method. Another option
is sub-classing and
have a server-side version which is a sub-class of your shared class - I've
done that before and
IMHO its a bit more elegant.

I was hoping to do it within a class.
For instance, say have method a() only available on the server.

In thesourcetag of the module XML file you can specify the
subpackage associated with the classes you want GWT to compile.
You can even exclude some particular classes using a pattern based
filter:http://code.google.com/intl/it-IT/webtoolkit/doc/latest/DevGuideOrgan...

Re: RequestFactory entity proxies can't be cloned.
I can kind of see how your proposed solution would work, and I guess that could be done if necessary. I was trying to use separate request contexts, and got the aforementioned crossing streams error, but I was editing the whole document. The solution you suggest is hardly ideal though, so I'm wondering if someone has another idea. -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.
