Re: Image element will hang test execution
Greg, thanks for your reply.
I've given a test example above that hangs... I don't understand what
you mean by all those steps :). Just copy-paste the code above and run
it as a gwt testcase.

Right before this object's constructor, try to create the image object

first think your app does. If that does work, you've got something in
your app breaking the image. If that doesn't work, you have a bad
image. If they both work, then you've got a problem somewhere in your
object, so try allocating the Image at different points of the
constructor, until you've found the command that breaks the Image
loading process.
You can also try a different Image, to see if the SPECIFIC Image is
the problem there, or if any image is a problem.
IOW, at this point we have no idea whether or not it's a GWT problem,
and (since you haven't given us the code necessary to replicate the
problem) noway to help you if it IS a GWT problem.

Hi,

}
}
The hang happens on Image:237 =

Now, I'm not trying to test the Image constructor, but I have complex

RequestFactory entity values updated before merge called
Hello everybody! I've got a problem: I'm using Hibernate version 3.6 and RequestFactory together to manage all the database work. Until now i did not run into any problems. But now I've got the case that I want to update an entity (merge), but need access to the old values of the entity in the update method. I realized, surprisingly, that when i do a find(entityToUpdate.getId) within the update method i already get the new values, although i did not call flush, merge, persist or anything like that. Does the RF something when i'm sending a proxy over the wire to explain this behaviour or is it because of my Hibernate settings. I've got to admit that i am not an expert in Hibernate, but until now i could do everything i need to. Thanks for any advice!

Re: Stack Layout Panel - strange layout problem after switching tabs!
Dear Philippe,
yeah this was the reason and the workaround works as hell! Many
thanks! This saved my fascination for building GWT apps! :-)
But some questions remain:
Why does this only affect IE7? I first thought that it was a bug
originated in the browser specific generated code. But I could
reproduce it in hosted and web mode, but only in IE7, not in FF. So,
where exactly is the bug?
It seems that it only affects DockLayoutPanel inside a
StackLayoutPanel. I remember that the bug was not present when I had
other Panels inside my StackLayoutPanel.
For now, I just implemented a forceLayout method in MyStackLayoutPanel
as follows:
-
public class MyStackLayoutPanel extends StackLayoutPanel
{
...
public void forceLayout ()
{
IteratorWidget itr = iterator ();
while (itr.hasNext ())
{
Widget w = itr.next ();
if (w instanceof DockLayoutPanel)
{
((DockLayoutPanel) w).forceLayout();
}
}
}
-
As you can see, I only handle children that are DockLayoutPanels,
because I know that my problems are solved with it. However, how would
a more generic workaround look like?
And last but not least: Will this be fixed in future GWT versions?
(This is not the first IE7-specific piece of code in my project...)
Again, a thousand thanks!

Re: Outofmemory when call findxxx many times Requestfactory+JPA
Just a short note: You can remove the @SuppressWarnings annotation when using em.createQuery(query, Scenario.class) Your server code seems ok. We do not use RequestFactory yet but we are sometimes fetching a lot of entities on our server (Glassfish 3.1 + bundled Eclipselink 2.2) and haven't seen any problems yet. For each request to our server we create a new EntityManager instance and when we are done we call em.clear() and em.close(). Our EntityManagerFactory is pretty much a singleton and will be created once for each new customer doing the first server request. We also deactivated the EntityManagerFactory cache (second level cache). For testing purposes you can clear the second level cache in your code by calling emf.getCache().evictAll(). Maybe you can create a rpc remote service and call your findXXX method via the service to see if its a RequestFactory bug or if its a JPA related problem. -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: Deferred Binding, Gin in library/widget ?
@Brian: I agree, after thinking a little bit more about that problem and taking your comments into account I think that deferred binding might not be really suitable for my use case. I also agree that the best approach is to set the datasource in the constructor thus enabling users to use Dependency injection if they want. But do I have to annotate the constructor with @Inject in order to allow for DI ? (because in that case I would create a dependency to gin and guice in my standalone library which i want to avoid). -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: Deferred Binding, Gin in library/widget ?
Hi Phillipe Thanks for the interesting comments. I am still trying to fully understand dependency injection and sometimes I am not sure that I have ;-) I agree that dependency injection is more powerful and flexible compared to deferred binding. So the three cases you described apply when I want to mix deferred binding with DI? After thinking a little bit about my problem and taking Biran's previous comments into account I decided against deferred binding and for designing the API so it can be used with DI (dependency injection). I haven't really decided whether the url is going to be an application wide resources or if it can be set to different values on an instance base. But does it really make a difference in regards to DI? In both cases I would try to inject the URL as a constructor injection? (I could use annotated dependency injection for different URLs in the app I guess?) The HttpDataSource class is a special implementation of the DataSouce and doesn't necessary mix with different datasource implementations. For example I might add a HTML5 LocalStoreDataSource which doesn't need an URL ressources but might take something else in the constructor. In your opinion what is the best DI setup for this use-case? And do I have to annotate my DataSource constructors with @Inject if I want to enable DI? This would create a dependency to GIN/GUICE in my library which I want to avoid. thanks in advance Uemit -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

I started working on something like that at work, and we will eventually open source it. For now, I can use Slf4J in my client code. In DevMode, it will use whatever Slf4j implementation it finds in the classpath (which means that it will write to the console, not to the DevMode window), and it compiles out in prod mode. I've been thinking recently about just wrapping java.util.logging (and using jul-to-slf4j.jar to format my logs using logback) instead of my default, emulated NOPLoggerFactory (used in web mode only), but we actually don't use it that much in client code (and overall), so I didn't invest any more time in it for now. There's also a project on GitHub: https://github.com/derjan1982/slf4gwt more like gwt-log than JUL integration in GWT though, IIRC. I would like to be able to use logging.properties file to define formatting, which I believe is not possible with java.util.logging.

Re: RequestFactory entity values updated before merge called
JPA provides two modes of flushing query objects namely AUTO and COMMIT (which are defined in FlushModeType Enumeration). If the AUTO mode is set on the Query object which is the default one, then any changes made to entity objects will be reflected the very next time when a select query is made. That means that the persistence engine must make sure to update all the states of the entity objects which will affect the results of a SELECT query.

Re: CellTable: Unable to combine CSS-selectors
Thank you John, Brian and zakness. All of you were spot on!
I was confusing descendant selectors and multiple selectors. I guess the
reason I was having such a hard time figuring out this one was because the
parent TR had many of the same styles applied. This gave the illusion that
the way I was trying to use the selectors was working in some cases but not
in others.
Removing the space and thus turning it into a multi class selector solved
the problem:

CellTable: Prevent styling of selected rows
Hi awesome people
I'm trying to control which of the columns in a CellTable will trigger a
SelectionChangeEvent by implementing CellPreviewEvent.Handler.
The problem is that even if I cancel the SelectionChangeEvent, the
CSS-styles for *selected rows* are still applied (
.cellTableKeyboardSelectedRow), which means it looks like the row i being
selected to the user. Is there any way to change this behavior, or is there
some other way of controlling which columns trigger selection? I have a
CellTable with several button columns and several text columns, and I want
to disable selection on some of them.
The code below creates a CellTable with to columns. When you click on one of
the columns an alert-box pops up, and when you click other the nothing pops
up, but the row looks like it's being selected.
CellTableMyProxy cellTable = new CellTableMyProxy(50);
final NoSelectionModelMyProxy selectionModel = new
NoSelectionModelMyProxy();
selectionModel.addSelectionChangeHandler(new SelectionChangeEvent.Handler()
{
public void onSelectionChange(SelectionChangeEvent event) {
Object selected = selectionModel.getLastSelectedObject();
if (selected != null) {
Window.alert(Selected something);
}
}
});
CellPreviewEvent.HandlerMyProxy selectionEventManager = new
CellPreviewEvent.HandlerMyProxy() {
@Override
public void onCellPreview(CellPreviewEventMyProxy event) {
if (event.getColumn() == 0) {
event.setCanceled(true);
}
else {

String type = nativeEvent.getType();
if (click.equals(type)) {
if (nativeEvent.getCtrlKey() || nativeEvent.getMetaKey()) {

}

Re: can we print page without open print dialog
Would you want some random web page to be able to start your printer going, printing out whatever the writer of that web page wants, without any warning to you, or any way to stop it? No? Then no, you can't print from a web application running in a properly functioning web browser w/o first putting up a print dialog that lets teh user control what you're doing. :-) Greg On Feb 25, 3:53 am, Neel neel.3.ka...@gmail.com wrote: Hi Is it possible to print page without open Print Dialog. -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Search for EnterButton in this group. At the top is a class

Re: gwt mvp sessions
Hi Thomas, On Fri, Feb 25, 2011 at 8:49 AM, Thomas Broyer t.bro...@gmail.com wrote: Of course! I didn't mean to imply that you shouldn't secure your app, but honestly if someone succeeds in hijacking your session, then he could possibly do it before loading the host page, so that your GWT app will run with the hijacked session, and the auth token in the request payload won't be of any help. First off, the hacker couldn't have access to the local cookie on the user's machine unless the user has been infected with a virus. If the user's computer has been infected with a virus that can some how target local cookies then this user has a lot more to worry about than someone hijacking their session. So let's rule that scenario out. Secondly, if the hacker could somehow manage to hijack your session - meaning they've some how coerced the request to use a different value for the session id) and do it before loading the host page it wouldn't make a difference if every Servlet method that is called does the following: 1) checks each payload for an auth token (a value equal to the sid stored as a cookie on the client) and 2) compares the auth token's value to the HttpSession's session id value. If they aren't the same then throw a custom exception and catch it on the client and authenticate the user (either form-based auth or some other method such as Google Account, OpenId, et. al) Not only does the above protect against session hijacking but it also solves the how do I know if the session is timed out question. So you solve two use cases in one implementation which isn't bad. You can even use filters to do this eliminating the need for every Servlet method to implement this logic. It's a simple, viable solution to an attack that is quite prevalent these days. It's implementation on both the client and server are trivial yet (I would venture to guess) is regrettably ignored by many if not most developers (to which I am not limiting to GWT developers). Of course, having a secure transport protocol (ie SSL) is the ultimate solution but not every site or every page on a site requires SSL yet every page that communicates with the server on every site requires a proactive defense against these kinds of attacks. -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

How AsyncCallback works? - RPC services
Hi, Not sure how the AsyncCallback works in GWT. Could somebody share please? 1) Will it create a thread and polls the server ? or 2) Will servers register's client IP and when result is available makes a fresh TCP/IP connection to client and calls client. Within this call back, will server calls a method on skeleton (server side stubs) for remote call ? or It just makes a tcp call and client handles calling the Async method ? -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Hi, PARAG,
Whether 0 is the correct result or not is debatable. After all, an
empty string is not a number at all, therefore for number zero, the
zero symbol itself is not a leading zero.
Perhaps the documentation should clarify that only leading zeros of
the whole portion and trailing zeros of the fraction portion of the
number will show as absent, not just any zero symbol.
As for solution for your problem, just put an if statement:
if (num == 0) {
return ;} else {
return formatter.format(num);

Re: is it possible to use an SLF4J adapter in GWT to wrap java.util.logging ?
May I ask why do you need something like that? Basically everything what you need is inside of gwt-user package. Let's look what is actually SLF4J. It's just an interface for many logging frameworks [java.lang, apache.logger , etc]. So when you have plenty of libraries using different logging frameworks and want to collect all these logs, you will use SLF4J for agregating these logs to same format. Now let's look what is inside gwt. There is pack with loggers to firebug, jsconsole, system.out for dev mode, logger with remoteservice to send logs to server. When you instantiate logger and make a log, enabled frameworks are used. I agree thet format of log is horrible, but inheriting this loggers and setting up own log formatter solve this problem. SO you just need familiar use of gwt logging. Make a class LoggerFactory.getLogger ane one Logger class , make a mapping from java.lang levels to SLF4J logger . - 2 classes and 1 class per log channel. Make it yourself.

I started working on something like that at work, and we will eventually open source it. For now, I can use Slf4J in my client code. In DevMode, it will use whatever Slf4j implementation it finds in the classpath (which means that it will write to the console, not to the DevMode window), and it compiles out in prod mode. I've been thinking recently about just wrapping java.util.logging (and using jul-to-slf4j.jar to format my logs using logback) instead of my default, emulated NOPLoggerFactory (used in web mode only), but we actually don't use it that much in client code (and overall), so I didn't invest any more time in it for now. There's also a project on GitHub:https://github.com/derjan1982/slf4gwtmore like gwt-log than JUL integration in GWT though, IIRC. I would like to be able to use logging.properties file to define formatting, which I believe is not possible with java.util.logging. I believe you can (at least in DevMode I mean, or when using a RemoteLogHandler), though you might have to make your own Formatter class (or pick a third-party one). -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

However after adding the 90 days milisecs to it, the result works out as 1297831991894 (less than before the addition).

Redirecting to jsp
Hi,
In my celltable, i have one button column.
In the fieldAdapter(), i am opening a new window using Window.open( url,
_blank, );
It opens a new window withe the url using the http get() method. I want to
open this window with http post() method. How can i acheive this ?
I think it is not possible at the client side using java script, so i though
it to redirect to a jsp as follows
HttpServletRequest req = getThreadLocalRequest();
HttpServletResponse res = getThreadLocalResponse();
res.addHeader(Referer, http://www.domain.com;);
try {
res.sendRedirect(param);
} catch (IOException e) {
e.printStackTrace();
}
but this does not work. Nothing happens when i click the button.
How it is possible to redirect to a jsp page from gwt?
Thanks

Own GWT library without web.xml

I get the error message The web.xml file does not exist in the master project. Right, I don't have a web.xml file in the master project because it is in the specialised project.

How to implement custom find methods in GWT+roo scaffolding app
Hellow everyone, I started to deal with GWT+roo scaffolding ap and
found the idea very cool. Thank you guys!
But I found it hard for me to understanf how to implement custom
find methods like for example - findAllEmployeesByName.
I looked all the documentations and it's written there that I can add
this method to Entity object itself like this:
@RooJavaBean
@RooToString
@RooEntity
public class Employee {
.
@NotNull
private String displayName;
@SuppressWarnings(unchecked)
public static ListEmployee findAllEmployeesByName(String name){
return entityManager().createQuery(select ... from Employee
o).getResultList();
}
}
I added it but nothing happend. No code generation started.
I see all finder methods are in Aspects which are generated by Roo
itself and I can't put my code there.
Can you guys give me some hint please.
With respect

Re: Spring GWT Integration
I think it is flexible enough to be used without an official support. Still depends on how you want to use it. As a rule of thumb, I normally see it like this: - If your architecture is built around SpringMVC such that your view is handled by Spring, then use Spring - If your architecture is towards the MVP approach (view is handled by GWT), then use GWT. - Obviously, you can use both in a project, your view determines whether you should use Spring or GWT. - Use GWTController for GWT view and SpringRoo controller for JSP(x) view. This is because GWT can handle view on it's own due to its Layout Panels, DOM Manipulation features, event management, Drag and drop features, fantastic cross-browser CSS support and data presentation model. When you create a controller using SpringRoo, it's best you make use of SpringRoo controller. Why? It does every thing for you. Creates the jsp(x) files for each of the controller overrides that requires a view.

Re: Upadate Data of CellList
If you're only adding to the end of the list, then keep track of how many items you've already added, and call updateRowData (prevNumAdded - 1, newData); Unfortunately this works only on initial filling. The second time I call this I've got nullPointers in my cell.render method for the first items added. This is another thing I dont understand: why is the render method call for my whole list and not only for the one that I've added in the updateRowData method and why the first 10 are null. Also I dont understand which method forces the list to re render? If you're changing things / adding things in the middle, you can do all sorts of complicated things to figure out where the changes are, and only give your CellList the changes, but you're probably better off simply replacing everything and letting CellList worry about it. Draw the whole list is not that good cause you have a short delay where the list disappears.

Selectively preserving CSS class references in *.ui.xml
I have a UiBinder managed Composite widget with a SplitLayoutPanel
at top. I'm trying to style the .gwt-SplitLayoutPanel-HDragger like
so...
ui:style type='com.example.ContentPanel.MyStyle'
.gwt-SplitLayoutPanel-HDragger {
background-color: #FFA65E;
cursor: e-resize;
}
/ui:style
but GWT renames the style during compilation thinking it is an
'internal' style.
Similarly, I might declare a style class to expose for external
reference, yet still provide a default style. I wouldn't want class
in that default style to be renamed.
How do I prevent GWT from renaming some of these class references in
the style sheet?

Re: Can I set some piece of code to be ignored by GWT compiler
Any code that is only run server-side should be outside the packages declare for compilation in your .gwt.xml file. For example, if you have data structure classes shared by both client and server, you can put them in a .shared package (and update your .gwt.xml to compile this package). However, your database methods to store and retrieve these classes should be located elsewhere, outside your .client and .shared packages.

First off, the hacker couldn't have access to the local cookie on the user's machine unless the user has been infected with a virus. If the user's computer has been infected with a virus that can some how target local cookies then this user has a lot more to worry about than someone hijacking their session. So let's rule that scenario out. I can setup an web page at attacker.appspot.com that sets a cookie with Domain=.appspot.com, and it'll target every appspot.com app out there. If victim.appspot.com uses its own authentication mechanism and its own cookies, I can then easily set a cookie to a user's browser visiting attacker.appspot.com and redirect it to victim.appspot.com, and he would then be automatically authenticated with my own session (session fixation attack). Secondly, if the hacker could somehow manage to hijack your session - meaning they've some how coerced the request to use a different value for the session id) and do it before loading the host page it wouldn't make a difference if every Servlet method that is called does the following: 1) checks each payload for an auth token (a value equal to the sid stored as a cookie on the client) and 2) compares the auth token's value to the HttpSession's session id value. If they aren't the same then throw a custom exception and catch it on the client and authenticate the user (either form-based auth or some other method such as Google Account, OpenId, et. al) But if the auth token is initialized from the cookie (or somehow attached to the authenticated user) and the attacker managed to set the cookie value on behalf of the webapp (or at least do a session fixation attack), then those two checks won't detect it. -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: Deferred Binding, Gin in library/widget ?
I haven't really decided whether the url is going to be an application wide resources or if it can be set to different values on an instance base. But does it really make a difference in regards to DI? The difference is that if you provide the url on an instance basis than your creation mechanism has to be aware of that url. In other words, all your DataSource-derived classes need to take a URL at creation time. (They could ignore it if they don't need it, but it's a code smell.) If the URL is an app-wide resource, then you can create both StandardDataSource and HttpDataSource without specifying a URL so they are effectively the same. If you have a limited number of URLs to different resources, an option might be to extend HttpDataSource with, say: TwitterDataSource FlickrDataSource ... These DataSource can then have a parameter-less constructor. Cheers, Philippe -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: gwt mvp sessions
You are talking about using request cookies so of course the scenario you describe might be possible. Everyone knows they are vulnerable and hence their ease of hijacking. The right way to do it is not using request cookies at all on the server because they cannot be trusted - the auth token must be delivered to the server as part of the payload and it must never be read from a request cookie.

First off, the hacker couldn't have access to the local cookie on the user's machine unless the user has been infected with a virus. If the user's computer has been infected with a virus that can some how target local cookies then this user has a lot more to worry about than someone hijacking their session. So let's rule that scenario out. I can setup an web page at attacker.appspot.com that sets a cookie with Domain=.appspot.com, and it'll target every appspot.com app out there. If victim.appspot.com uses its own authentication mechanism and its own cookies, I can then easily set a cookie to a user's browser visiting attacker.appspot.com and redirect it to victim.appspot.com, and he would then be automatically authenticated with my own session (session fixation attack). Secondly, if the hacker could somehow manage to hijack your session - meaning they've some how coerced the request to use a different value for the session id) and do it before loading the host page it wouldn't make a difference if every Servlet method that is called does the following: 1) checks each payload for an auth token (a value equal to the sid stored as a cookie on the client) and 2) compares the auth token's value to the HttpSession's session id value. If they aren't the same then throw a custom exception and catch it on the client and authenticate the user (either form-based auth or some other method such as Google Account, OpenId, et. al) But if the auth token is initialized from the cookie (or somehow attached to the authenticated user) and the attacker managed to set the cookie value on behalf of the webapp (or at least do a session fixation attack), then those two checks won't detect it. -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: gwt mvp sessions
You contradict yourself (compare the HttpSession's ID with the auth token –the HttpSession is maintained by a cookie, whose value generally is the session's ID– vs. do not send the auth token in a cookie), but that's not the problem. The problem is: how are you initializing the auth token on the client side, and how you associate it with the user on the server-side? The client and server have to share some knowledge at some point, and if you have use form based authentication on another web page (i.e. your app's host page is protected and cannot be accessed without being authenticated), then the only way (not accurate, but that's how 99.999% of auth is done, because the alternative comes with a UX penalty) to transfer the authentication from the login page to the app's page is to use either a cookie or pass a unique token in the URL, both of which can be hijacked. -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

GWT 2.2 /Eclipse 3.6 Pugin Development Mode Trouble
Hi!, I am working for my client to explore the possibility to upgrade from GWT 2.0 to GWT 2.2. My first step was install a bran new Eclipes 3.6 and then installed GWT 3.6 plugin. I ran into troubles when downloading ( many times of timeout), so I simply downloaded the plugin and installed it manually. Simply created first project ExampleWebApp following the what described in the website. When creating the web app project, I selected Use Google Web Tookit but not select Use Google App Engine. When I ran it, it did not give any error info from the console nor in the Development Mode window. When I tried to connect from browser http://127.0.0.1:/StockWatcher.html?gwt.codesvr=127.0.0.1:9997 I got Unable to connect popup from the browser. I have tried to change the 127... to the formal host name or ips, it gave me the same. The example works for my GWT 2.0 installation. I appreciate any help or hint. Thanks! BTW, here is the output from the console, when I turned on the trace when running: == hecking for updates First launch was 12d576e05b9 Checking for new version at http://tools.google.com/webtoolkit/currentversion.xml?v=2.2.0id=12d576e05b9r=tags/2.2.0@9724e=DevMode Started code server on port 9997 Parsing file:/C:/Documents%20and%20Settings/C123690/workspace2/ ExampleWebApp/war/WEB-INF/web.xml startElement: web-app startElement: servlet startElement: servlet-name characters: greetServlet endElement: servlet-name startElement: servlet-class characters: com.example.server.GreetingServiceImpl endElement: servlet-class endElement: servlet startElement: servlet-mapping startElement: servlet-name characters: greetServlet endElement: servlet-name startElement: url-pattern characters: /examplewebapp/greet endElement: url-pattern endElement: servlet-mapping startElement: welcome-file-list startElement: welcome-file characters: ExampleWebApp.html endElement: welcome-file endElement: welcome-file-list endElement: web-app Loading modules com.example.ExampleWebApp Module location: file:/C:/Documents%20and%20Settings/C123690/ workspace2/ExampleWebApp/src/com/example/ExampleWebApp.gwt.xml Loading inherited module 'com.google.gwt.user.User' Module location: jar:file:/C:/eclipse-new/plugins/ com.google.gwt.eclipse.sdkbundle.2.2.0_2.2.0.v201102111811/gwt-2.2.0/ gwt-user.jar!/com/google/gwt/user/User.gwt.xml Loading inherited module 'com.google.gwt.canvas.Canvas' Module location: jar:file:/C:/eclipse-new/plugins/ com.google.gwt.eclipse.sdkbundle.2.2.0_2.2.0.v201102111811/gwt-2.2.0/ gwt-user.jar!/com/google/gwt/canvas/Canvas.gwt.xml Loading inherited module 'com.google.gwt.user.User' Module 'com.google.gwt.user.User' has already been loaded and will be skipped Loading inherited module 'com.google.gwt.canvas.dom.DOM' Module location: jar:file:/C:/eclipse-new/plugins/ com.google.gwt.eclipse.sdkbundle.2.2.0_2.2.0.v201102111811/gwt-2.2.0/ gwt-user.jar!/com/google/gwt/canvas/dom/DOM.gwt.xml Loading inherited module 'com.google.gwt.dom.DOM' Module location: jar:file:/C:/eclipse-new/plugins/ com.google.gwt.eclipse.sdkbundle.2.2.0_2.2.0.v201102111811/gwt-2.2.0/ gwt-user.jar!/com/google/gwt/dom/DOM.gwt.xml Loading inherited module 'com.google.gwt.core.Core' Module location: jar:file:/C:/eclipse-new/plugins/ com.google.gwt.eclipse.sdkbundle.2.2.0_2.2.0.v201102111811/gwt-2.2.0/ gwt-user.jar!/com/google/gwt/core/Core.gwt.xml Loading inherited module 'com.google.gwt.dev.jjs.intrinsic.Intrinsic' Module location: jar:file:/C:/eclipse-new/ plugins/com.google.gwt.eclipse.sdkbundle.2.2.0_2.2.0.v201102111811/ gwt-2.2.0/gwt-dev.jar!/com/google/gwt/dev/jjs/intrinsic/ Intrinsic.gwt.xml Loading inherited module 'com.google.gwt.lang.LongLib' Module location: jar:file:/C:/eclipse-new/ plugins/com.google.gwt.eclipse.sdkbundle.2.2.0_2.2.0.v201102111811/ gwt-2.2.0/gwt-dev.jar!/com/google/gwt/lang/LongLib.gwt.xml Loading inherited module 'com.google.gwt.emul.Emulation' Module location: jar:file:/C:/eclipse-new/ plugins/com.google.gwt.eclipse.sdkbundle.2.2.0_2.2.0.v201102111811/ gwt-2.2.0/gwt-user.jar!/com/google/gwt/emul/Emulation.gwt.xml Loading inherited module 'com.google.gwt.logging.LogImpl' Module location: jar:file:/C:/eclipse-new/ plugins/com.google.gwt.eclipse.sdkbundle.2.2.0_2.2.0.v201102111811/ gwt-2.2.0/gwt-user.jar!/com/google/gwt/logging/LogImpl.gwt.xml Loading inherited module 'com.google.gwt.xhr.XMLHttpRequest' Module location:

Re: gwt mvp sessions
I am not dismissing your scenarios outright as I never said that the method was foolproof and I also said that only SSL will give you something close to that. Also lets not forget that if the user manages to be lured to an attackers site via a link in an email for instance and then doesn't notice that they are then redirected to another site then they have bigger problems than having their session hijacked lol. However, there are ways to mitigate even the cross-subdomain attack that you use as an example... On Fri, Feb 25, 2011 at 2:20 PM, Thomas Broyer t.bro...@gmail.com wrote: This is where you fail to understand me: you make the assumption that the authentication process takes place, while I'm talking about bypassing it with a session-fixation attack. I understood perfectly, Thomas. To reiterate, the attacker will have had to authenticate in order to acquire a valid sid which he then stores and waits in prey for the user to respond to his email with a link to his site. When the user takes the bait and visits the attacker's site the attacker redirects the user to another site including the sid as a query parameter. One possible scenario (easily mitigated through the use of your own domain name): *Attacker*: authenticates to victim.example.com, grabs the cookies in use, store them at attacker.example.com (note: same domain, different subdomains, much like appspot.com hosted apps) At this point the request hits the server and the session id is set the query parameter, the same one as the attackers. This attack can be mitigated by changing the session ID when users logs in and to additionally require the user to authenticate on every important request. A pain in the rear for the user of course but it will largely work. The fact that it does work is due to the reluctance to require users to log in for every important request. Sure enough, even if you used SSL it would require that every request uses it in order to be close to 100% protected from this kind of attack. The only sites I know that do that are some banks. I believe Citibank does for instance. Interestingly I believe Facebook announced that they will be rolling this out to all their members. It will be interesting to see how it affects the performance of their site. Perhaps requiring every one to use SSL for every request is the right approach. Maybe we should all be going in that direction but service providers might be loathe to provide this service as it adds additional demands on their servers that they might not be able to handle and the users might complain because of the increased latency. Perhaps using HttpOnly headers would also mitigate this kind of attack. I don't think App Engine supports it though but I wish it did. The bottom line is this, it really comes down to a multi-faceted approach to security. One big wall isn't going to cut it and the more obstacles put up the less chances are that some malcontent will be successful. -- *Jeff Schwartz* http://jefftschwartz.appspot.com/ http://www.linkedin.com/in/jefftschwartz follow me on twitter: @jefftschwartz -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Multiple warnings in GWT 2.2
Hello all, I've searched and haven't found anything. I'm surprised that this hasn't been discussed (or I can't find it). After upgrading to GWT 2.2, I'm getting the warnings below both in dev mode and compiled. Is there anything I can do about it? Is it a known issue.

RequestFactory + ListEditor: empty record during first save
Hi All...
I have ListEditor of editable widgets. Each widget is a simple
TextBox.
Workflow:
- clicking add, populating new empty editor in the list;
- filling the TextBox;
- saving
The problem is that for the first 'save' I have a new record in DB
with version=0 all other fields=null. After that it's saving ok...
Here is some code:
public interface Driver extends
SimpleBeanEditorDriverListPhoneNumProxy, ListEditorPhoneNumProxy,
PhoneNumEditView {}
ListEditor editor = ListEditor.of(new FieldEditorSource());
ListEditor listEditor=editor;
List displayedList=listEditor.getList();
Driver driver = GWT.Driver create(Driver.class);
driver.initialize(listEditor);
driver.edit(new ArrayListPhoneNumProxy());
Here is how I'm creating a new editor:
PhoneNumProxy
proxy=requests.phoneNumRequest().create(PhoneNumProxy.class);
displayedList.add(proxy);
Also, I'm doing listEditor.flush()
Any ideas what's wrong? Thx!

Re: gwt mvp sessions
With RPC I define all my RPC synchronous methods taking a string parameter
whose value will be assigned from the cooke storing the sid. On the server,
the handler will compare this string value to the value returned from the
Session.getId() method. If they aren't the same I throw a custom exception
which is caught on the client in the overloaded OnFailure method of the RPC
call.
Here's the typical code for a server-side handler:
@Override
public SingleRPCPayloadSomeTyoe someMethod(String clientSid, ...)
throws MyCapabilityDisabledException {
HttpSession session = getThreadLocalRequest().getSession(true);
String sid = session.getId();
if (clientSid.equals(sid)) {
.
.

return payload;
} else {
throw new MyInvalidSessionException();

Re: gwt mvp sessions
Thanks Jeff, With RPC, this way is understood. Similarily, I have some idea with RequestFactory also like requestFactory.serviceRequest().getAllEntities(clientSid); and on the server side, in getAllEntities(String clientSid) i can verify the same way you did. But this way is forcing me to put an extra parameter in all my business methods. I am sure there are other ways. Any Ideas?

Re: gwt mvp sessions
You could use the Command pattern as with GWT-RPC using a ValueProxy as the command object, but I'm not sure what you'd gain by it as you'd lose all the RF functionality related to entities. As it currently stands, you would need to modify the RF transport protocol, perhaps with a ServiceLayerDecorator. Are you convinced that the token needs to be part of the payload vs. request header? It's much easier to modify the header by extending DefaultRequestTransport as Thomas has pointed out elsewhere. /dmc On Fri, Feb 25, 2011 at 7:34 PM, veenatic praveen.bit...@gmail.com wrote: Thanks Jeff, With RPC, this way is understood.

OK, maybe the ButtonCell is not the best example, as its appearance and behavior are quite… limited, but still. Or could, in this case, the Appearance have hasHoverBehavior or similar that the Cell would use to decide which events it's interested in? (so if you want your onHover method to be called, you'd first have to override hasHoverBehavior to return true). As an alternative, a few such behaviours could come in mixin interfaces, and the Cell would advertise (in the javadoc) which ones it supports (the ButtonCell would then only say it handles mouseover events if the Appearance is an instanceof HasHover). You wrote: Finally, note that Appearance is an abstract class. This allows us to add more state logic in the future without breaking existing Appearances. For example, we could add new methods setRightFlush() and setLeftFlush() which would make the right and left edges of the button flat, such that they could be lined up next to each other.

It would be nice to get rid of the FooListeners/SourcesFoo stuff that is just clutter now and has been deprecated since 1.6 I have no problem with ButtonWidget naming style however. In eclipse you can just type BW and control-space and eclipse will find all classes with B...W... in their name.

I added the following code to CompilationTest around line 566:
assertTrue(origRef instanceof DirectRef);
assertTrue(newRef instanceof SerializedRef);
(I had to make SerializedRef default access.) This code passed.
Basically, at some point I was reading in cached units, but they were
being invalidated when running the Dependencies.validate() method. I
traced it back to null values for CompiledClass. The examples I was
looking at had writeReplace as a protected method so I changed the
protection.
I read over the documentation for Serialization and what you are saying
makes sense to me. I changed protected back to private and caching
still works. The fix must have been another change I made, but I can't
imagine what.
I added your suggested lines to the unit test.
Do you think I should back out this change? I agree it must not have
been what solved the problem, but it seems reasonable to expect that a
subclass would need similar logic.

Nah, there's no reason to revert it. I just wanted to be sure I
understood it correctly.

[gwt-contrib] Severe regressions with editor overhaul at r9666
Hi G-Men, hi Bob, hi Ray, On Monday, I switched our app (I mean everyone in the team, not only on a local branch) to GWT trunk@9753 with a few patches that are still in review, in the hope that my team stop harass me with bug reports about editors and RequestFactory (my first idea was to switch to 2.2 and live with the remaining bugs, but we'll soon show the (far from finished) app to our clients and, even worse, make them test it for a couple of days, so it has to work better than what 2.2 gives us). It unfortunately turned out to have been a bad idea, as we discovered 3 major regressions introduced by the overhaul at r9666 (that 666 in the rev. number must be a sign): 1. RequestFactoryEditorDriver failing to collect path when a dotted path is given to the @Path annotation (issue 6066http://code.google.com/p/google-web-toolkit/issues/detail?id=6066, OMG a hidden 666 once more!) 2. EditorDelegate's getPath is wrong when the subeditor is referenced with a dotted path in a @Path annotation (issue 6076http://code.google.com/p/google-web-toolkit/issues/detail?id=6076 ) 3. ListEditor subeditors' value is not flushed when used with a RequestFactoryEditorDriver (issue 6081http://code.google.com/p/google-web-toolkit/issues/detail?id=6081 ) I have fixes for the first 2, but that last one is a bit trickier to fix * correctly* (I'll apply a dirty fix to our copy, running the visitor twice and living with the performance penalty; it should be OK as we're fortunately only targeting modern browsers, our main target being Firefox 4). FWIW, here's the list of patches I also apply to make our 2.3-SNAPSHOT version: - Issue 5599http://code.google.com/p/google-web-toolkit/issues/detail?id=5599: HasDataEditor doesn't handle removes from the list (never calls HasData#setRowCount) - Issue 5952http://code.google.com/p/google-web-toolkit/issues/detail?id=5952: RequestContext.isChanged returns true just after an edit() whenever there's a List or Set - Issue 6015http://code.google.com/p/google-web-toolkit/issues/detail?id=6015: Editor generator can generate filenames too long for almost all filesystems - Issue 6016http://code.google.com/p/google-web-toolkit/issues/detail?id=6016: EditorContext generated class name should take parameterization into account - Issue 6040http://code.google.com/p/google-web-toolkit/issues/detail?id=6040: Editor framework does not support is / has methods (we can easily live without it, I believe we're no *yet* taking advantage of the fix) - Issue 6059http://code.google.com/p/google-web-toolkit/issues/detail?id=6059: ClassCastException in AbstractRequestContext.isChanged if you create()d a ValueProxy - http://gwt-code-reviews.appspot.com/1338807/ Introduces SkipInterfaceValidation annotation (I planned to remove a few of our ServiceLayerDecorator hacks and use the annotation, until the team reported me the bug I logged under issue 6081) All issues have however been verified against a fresh trunk checkout (that's when I can say I don't regret my switch to git-svn!) -- http://groups.google.com/group/Google-Web-Toolkit-Contributors

Re: [gwt-contrib] [RFC] GWT Widgets that ROCK!
Please take a look at the design doc and let me know what you think: The introduction mentions this: The assumptions that current widgets make regarding their structure prevent us from modernizing existing widgets without breaking applications that rely on the existing DOM structures. Which is true, but I don't think the Appearance pattern will alleviate this? E.g. if ButtonCell's default appearance outputs a certain DOM structure (whether by SafeHtml/otherwise), aren't users' apps going to couple themselves to the resulting DOM structure, either via custom Element-based hacks, or CSS rules that use selectors based on the DOM output? Seems like you'll still end up with DefaultAppearances that can never change? (Not that this sinks the whole proposal, but I thought I'd point it out. Though perhaps I'm missing something?) - Stephen -- http://groups.google.com/group/Google-Web-Toolkit-Contributors
Re: [gwt-contrib] [RFC] GWT Widgets that ROCK!
Please take a look at the design doc and let me know what you think: Out of curiosity, would this allow Panels (all the way up to RootPanel) to render their initial contents/major changes as one giant SafeHtml + set innerHTML operation, CellTable-style? If so, that seems pretty slick. - Stephen -- http://groups.google.com/group/Google-Web-Toolkit-Contributors
[gwt-contrib] Re: GWT Widgets that ROCK!
the idea seems fine but please keep an eye on the resulting size of JS :) On 24. Feb, 23:28 h., John LaBanca jlaba...@google.com wrote: GWT Contributors - I drafted a proposal for a new pattern that the GWT team will use to replace existing GWT widgets with newer, shinier widgets. The proposal hits on the major pain points that users have with existing widgets: - Replace the styles of a widget instance - Replace the DOM structure of a widget instance - Reskin an entire GWT app (DOM and/or styles) - Allow third parties to provide skins - Isolate CSS code for each widget - Dead strip CSS code that is not used within the app - Separate presenter logic from DOM view - Offer an identical Cell equivalent of every (most) new widgets - Shared code between Cell and Widget - Expand Cell library Please take a look at the design doc and let me know what you think:http://code.google.com/p/google-web-toolkit/wiki/CellBackedWIdgets Thanks, John LaBanca jlaba...@google.com -- http://groups.google.com/group/Google-Web-Toolkit-Contributors

We're working toward that. We could add support for Cells in HtmlPanel, such that a UiBinder backed HtmlPanel containing only HTML and Cells would render as a sstring.

Seems like you'll still end up with DefaultAppearances that can never change? We can add a new appearance and maintain (or deprecate) the existing DefaultAppearance. The behavior would depend on the constructor that the user uses.
