Re: How to retrieve client's date in Short format as configured on client machine
Thanks Shades, Yes I tried using DateTimeFormat but here problem is that it never picks up changes done on Short format in Windows setting, it always displays short date in -mm-dd format. BTW I used: DateTimeFormat.getFormat(PredefinedFormat.DATE_SHORT).format(today) If there is any other option which I can try, do let me know.

But the point is that when the cell is rendered by the CellTable view, it
encapsulates it inside an other DIV and then put it in the TD. Then my Div
where I have applied a style will not have the max height of the TD so the
background color will not be fully applied to the TD. (The green of the OK
cell does not extend to the TD)
I got two ideas :
1/ Use css to extends the DIV to be the height of the TD. But setting
height: 100% did not work.
2/ Find a way to set manually a style to the TD. But there is nothing
on the CellTable api to access the TD after they have been rendered.
Is anybody have encountered this use case or have a solution please ?
Thanks in advance.

Re: Wishlist - What GWT developers want for Christmas
Just to report back. We were able to fix the issue and vaadin.com is no longer asking access to contacts when you signing in with your Google account. - Joonas On Thursday, December 13, 2012 12:03:47 PM UTC+2, Joonas Lehtinen wrote: Looks like our login form is using wrong scope from OAuth API. We'll fix this asap. We are definitely not using contacts (only stored information is persons own email-address). The wishlist page is quite simple and there is no admin inferface, so there is no be easy way to edit the contents. I think that better than trying to remove duplicates (and for that matter split comments with multiple proposals), you might like to analyze the most important stuff (both by seeing votes and number of similar entries) and publish a blog post about the analysis. This would probably clarify the results. On Wednesday, December 12, 2012 6:53:09 PM UTC+2, V.B. wrote: Hello Joonas, Thanks for your work on the report and for posting the wishlist. While I agree with the previous post that the majority of the 2,600 wishlist items are duplicates, there are several other valid items buried in the middle or near bottom of the list, which were not covered in the report. At the moment, these are not getting much attention because most voters stop looking after the first 50 or so items. For example, I found comments from a number of members about bugs that don't get fixed (e.g. some are even 2-3 years old), and patches that don't get accepted. I also saw some very important comments about how GWT needs to be better marketed/publicized in order to attract more developers. I suspect that issues like these would get much more up-voting if they were more visible. Perhaps a member of the community (me, for example) could volunteer to remove duplicates, or perhaps the list could be randomized every time it's viewed. Anything to make sure *all* the important issues get attention. On a separate note, I think even more members might log in and vote if not for the Access-to-Contacts requirement.

Re: Wishlist - What GWT developers want for Christmas
Hi, I'm the author of the piece of code that allows you logging in via various external services to vaadin.com, so all this is kind of my fault. Let me try to explain the situation. The first time you try to log in with, say, Google, we don't have any records of you. So we ask that service provider (Google in this case) for some information (I'll come back to the Contacts issue in a while). We are interested in the following data: user id, first name, last name, something suitable for a screen name and email. Then the user is redirected back to our server, with a form to give a bit more information about themselves, with as much as the service told about you pre-filled for you. Once the form is submitted, a Liferay user is created with the information given, and we link the user id given by the service Liferay user that was created. So, basically, we actually only use the service provider's user id. Everything else is just gravy; if the service says your name is John, we pre-fill your name as John to the register form. But if you change your name to Jack, you will be known as Jack to us, and no trace of the original John will be saved to our databases. Now, back to the Contacts issue. At the time of implementation, I tried to search a suitable API from Google to give what we needed. Unlike Twitter and Facebook (them being singular services,) Google is a mass of disparate services. I was unable to find anything generic - I needed to pick an OAuth (OpenID was out of the question, unfortunately) service both gave us the information we needed (basically an id - additional personal data would only be for the user's own convenience). But we also needed to be sure that every Google user would have that service enabled. So, the most suitable service that I found was Contacts. The fact that Google warns you that we get access to all your contacts is unfortunate in the sense that we are not interested in your contacts. There is no way for us to communicate to Google that we only need your user id from that service. That being said, I have now found https://developers.google.com/accounts/docs/OAuth2Login and am in the process of converting the login to use that in the future. This is a service specifically built to serve this kind of information: basic profile information. All of the above applies also to Twitter and Facebook - we are only interested in the user id that links a particular person to a user in our databases. Facebook seems to have changed the way their API works, and has started to provide too much information that we do nothing with. Once I'm done converting the Google bit, I'm going to fiddle around the Facebook settings to make sure that we ask for as little as needed.

Undefined attachEvent method in IE 8 using the GWT
We have developed a fairly complex business application using the Google Web Toolkit for the front-end rendering. Our application is working correctly on all modern browsers (Chrome, Firefox, Safari and IE9). In order to use standards mode we have put !DOCTYPE html in the GWT bootstrap. The problems arise when trying to use earlier IE versions and the application stops loading at the initial splash screen. After investigating, it seems that the GWT deferred binding correctly (1http://stackoverflow.com/questions/9769868/addeventlistener-not-working-in-ie8 , 2https://developer.mozilla.org/en-US/docs/DOM/element.addEventListener#Legacy_Internet_Explorer_and_attachEvent) callsattachEvent for IE 9 and addEventListener for IE 9. However, IE 8 throws a TypeErrorexception of type undefined_method for the attachEvent call. Note that this happens whenever GWT calls attachEvent and not just for a specific event. We can confirm because when we override the deferred binding for a specific class the problem appears at the next attachEvent call. Trying to override everything seems like a way to overcome the problem but it isn't optimal, especially keeping in mind that IE 9 is supposed to have the attachEvent method according to the specification. Does anyone know something about getting to the root of this problem? -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: GWT 2.4.0+ RequestFactory EntityProxy Validation
I have found out a few more details relating to this problem.
I have an Editor that implements LeafValueEditorListPhoneProxy.
When a user wants to add a new PhoneProxy to my editor I call
context.create().
Sometimes the user cancels the process.
When the user cancels the process the PhoneProxy created remains in the
list of beans that are sent to the server for constraint validation. This
always fails because the PhoneProxy has been cleared out by the cancel
operation.
It seems like there may be a bug here. The canceled ProxyPhone bean shows
up in the list to be validated but when I override the

Lienzo is now GA and it's Pixel Perfect!
All: Just a quick announcement letting everyone know that Lienzo is now GA! If you are looking to do anything canvas based, games, animations, new unthinkable widgets for either mobile or web based apps, I think you will find that Lienzo covers in this, its 1.0 version the vast majority of the things you will need. We have invested a great deal of time to make sure the library is as solid as it can be. However, nothing beats community feedback and new ideas. There are a handful of things that we plan on adding to the toolkit in the next release, but if you have any suggestions, please feel free to drop us a line. Lienzo is an Apache 2 library and its creation is the result of our own needs so we are not only producers but also consumers of the package. As part of this release we put a lot of effort into creating not only the software itself but also good resources to help you in your journey to create literally anything you can think of. That's how powerful canvas and GWT together we think can be. As usual, none, none of this would have been possible without GWT. We extend our gratitude to those that continue to make GWT better and hope that this latest addition helps others create things that were only possible in our imagination before, at least creating them in a much easier fashion. *Community: * https://plus.google.com/u/0/communities/111441257302891144143 *Lienzo User Guide:* http://wiki.emitrom.com/wiki/index.php/Lienzo_User_Manual *Lienzo Explorer:* http://www.emitrom-lienzo.appspot.com/ *Lienzo Download:* http://www.emitrom.com/lienzo/download The Emitrom Team -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: Multiple GWT sessions possible?
All good points from Jens. But, perhaps I'm missing something, but on most servers (Apache with mod_php, Tomcat) set a session token in the cookie on the first request you make to the server. Once the user logs in, you associate this session with that user by persisting their data data in $_SESSION or a session scoped bean. To that end, if you had your app open in one window, or 10 windows, they should all be on the same session because they are all passing the same session id cookie. Assuming that you're doing that, then a mechanism like Spring Security that would allow you to secure a context like **/secure/* to a given role (i.e. User) would be all you needed to do to protect your services/RPC's The one catch is application timeout. To get around this I return an HTTP error code (i.e. forbidden) and then have that caught in the failure handler for the RPC's. I extended the typical callback handler so all RPC's can handle session termination in a consistent, graceful way, prompting them to login again. With Spring Security you can even setup the request to us remember me cookies (if user selected that on login). In that case the server will cache the request, log the user back in, and forward the request, making the session timeout/relogin invisible to the user. Hope that helps.

To that end, if you had your app open in one window, or 10 windows, they should all be on the same session because they are all passing the same session id cookie. Thats exactly what I mean with one active session on the client. Only a single user is authenticated in all browser windows/tabs because you only have a single cookie with a single session id. You must log out or delete cookies if a second user should see the login screen again on the same browser (or you need a session timeout on server). The one catch is application timeout. To get around this I return an HTTP error code (i.e. forbidden) and then have that caught in the failure handler for the RPC's. I extended the typical callback handler so all RPC's can handle session termination in a consistent, graceful way, prompting them to login again. Its always a good idea to use a custom base class for RPC callbacks and/or use a custom RequestTransport/RpcRequestBuilder to handle these server responses. Its not only common HTTP error codes but also common exceptions like SerializationException/IncompatibleRemoteServiceException (GWT-RPC) that would indicate an application update that occurred while the user was idle in the app. -- J. -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Errors passing javascript variables to GWT
I'm following the example given here
https://developers.google.com/web-toolkit/articles/dynamic_host_page of
passing a global info javascript variable back to the GWT app when it
loads. E.g.
// In GwtHostingServlet's doGet() method...
writer.append(htmlhead);
writer.append(script type=\text/javascript\
src=\sample/sample.nocache.js\/script);
// Open a second script tag where we will define some extra data
writer.append(script type=\text/javascript\);
// Define a global JSON object called info which can contain some simple
key/value pairs
writer.append(var info = { );
// Include the user's email with the key email
writer.append(\email\ : \ + userService.getCurrentUser().getEmail() +
\);
// End the JSON object definition
writer.append( };);
// End the script tag
writer.append(/script);
writer.append(/headbodyHello, world!/body/html);
Then in my GWT app's EntryPoint class I have:
public static native String getEmail() /*-{
return $wnd.info['email'];
}-*/;
However when the app runs I get an exception saying:
$wnd.info is undefined
I've tried $doc but got the same error. I also tried window and document
but then it says document.info is undefined. What am I doing wrong?

[gwt-contrib] Re: Another approach to DevMode: taking advantage of browsers' remote debugging protocol
On Thursday, December 13, 2012 5:31:28 AM UTC+1, Ray Cromwell wrote:
How would you deal with re-entrancy though, e.g.
Java - JS - Java - JS
If you simulate a synchronous call from JS to Java by breaking, what
happens when Java calls back into JS? Everytime I thought about doing
this, it basically boils down to emulating continuations with CPS
transform, and that is quite onerous.
IIRC, ('cause I haven't looked at the code recently), it'd work the same as
today.
The idea is:
- implement a DevMode client in Java, equivalent to the C++ browser
plugins; this is easy, you just have to implement ClientBrowserChannel et
al.
- sending messages from the browser is done by setting a couple
variables and reaching a breakpoint, where the Java code then reads the
variables and sends the corresponding message to the DevMode server.
- sending a message to the browser is always done as a response, so
we're already stopped at the breakpoint, we can then set the variables and
resume execution, and the JS code will read the variables and do what's
appropriate (eval() code to load jsni methods, call a named function on an
identified object, etc.) Unless the message is a return, the JS code
loops over and reaches back to the breakpoint. See
https://code.google.com/p/gwt-in-the-air/source/browse/branches/oophm/src/net/ltgt/gwt/air/tools/shell/Oophm.as
That was almost 3 years ago though, so I might have missed something
obvious at that time, and I must say I haven't wrapped my head back around
it nowadays. The Chrome on Windows 8 doesn't support NPAPI issue reminded
me about it recently.
It seems much simpler to get the IDEs to support SourceMaps. For
example, IntelliJ already supports attaching to Firefox and Chrome JS
debuggers, once it supports SourceMaps, you should be able to have a
Java-debugger like experience with SDM.
Some things don't behave the same though (inspecting variables to begin
with, IIRC). SuperDevMode is great when you have a lot of JSNI because you
can step into JSNI methods, but it won't ever give you the same experience
as debugging Java code running in a JVM. One big advantage of SuperDevMode
is that you run the code in JS so you're sure that's how it'll behave in
production and nothing will be lost in translation (as it's *already*
translated),
but sometimes you might prefer to trade this off for a more integrated
debugging (at least that's what the initial reactions to SuperDevMode
implied); and there's also the issue with GWT-RPC serialization policies
that make using SuperDevMode tricky (apparently, I don't use RPC).
I'm all for continuing investing in SuperDevMode *as a priority*. I just
wanted to know a) if you thought about that alternative and b) suggest it
as an alternative that someone could volunteer to pursue (as a side
project).
