DateTimeFormat is not showing the locales specific formatting.
Hi,
I am using the DateTimeFormat and it's working fine for English, however,
in Arabic it's showing the exact value as shown for the English locale!
Here's the code:
public static String getFormattedDate(String date) {
final DateTimeFormat formatter =
DateTimeFormat.getFormat(-MM-dd'T'HH:mm:ss);
try {
final Date parsedDate = formatter.parse(date);
return
DateTimeFormat.getFormat(DateTimeFormat.PredefinedFormat.DATE_MEDIUM).format(parsedDate);
} catch (IllegalArgumentException e) {
e.printStackTrace();
return date;
}
}

How to use/force the default locale under certain conditions on runtime?
I have this requirement that for certain pages I want to show them in English locale for some given locales, because not all translations are available. If I didn't do so, some pages will have some items translated but not all, plus the styling of the non-English locale. Is there a good way to force English for certain condition, for instance, if a given url parameter was provided (even when the locale in the url is not English)? -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Hi Jens, Thanks for your replay but I don't think this helps me.

When the Image setResource is called does the image style get removed?
I am using the GWT Image widget then I am setting the image resource dynamically. When I do so the style class name of the image gets removed. I used UiBinder also tested on the java code as: image.setStyleName(styles.topLogo()); image.setResource(logo); This would also removed the style name, however, the following would not: image.setResource(logo); image.setStyleName(styles.topLogo()); So, my guess is that setResource foe some reason removes the previously defined style name.

The Frame class adds to the history tokens every time I change the URL, how can I stop that?
I noticed that a certain page would appear many times in the 'go back'
history tokens. After some digging I found out that the cause is the class
'Frame', specifically every time I change the URL like this:
videoFrame.setUrl(url);
the tokens would increase with the same current page! Which is very
annoying. I tried to stop the LoadEvent like this:
private HandlerRegistration handler;
handler = videoFrame.addLoadHandler(new LoadHandler() {
@Override
public void onLoad(LoadEvent event) {
handler.removeHandler();
}
});
With no luck what so ever. I tried other things but I got no where.
Any help?

How come the ScrollEvent is never fired in this code?
I'm playing around with some code, but I couldn't figure out how come
the ScrollEvent is never fired, I put a breakpoint on onScroll and it never
breaks!
Here is the code:
public class InfiniteScrollPanel implements ScrollHandler {
String text = Lorem ipsum dolor sit amet, consectetuer...;
ScrollPanel panel;
String height = 1200px;
String width = 200px;
public InfiniteScrollPanel() {
panel = new ScrollPanel(new HTML(text));
panel.setSize(width, height);
panel.addScrollHandler(this);
panel.getElement().getStyle().setBackgroundColor(rgb(216, 216, 216));
}
@Override
public void onScroll(ScrollEvent event) {
if (panel.getVerticalScrollPosition() == 1100) {
panel.add(new HTML(text));
}
}
}
Then I add it like this:
InfiniteScrollPanel demo = new InfiniteScrollPanel();
RootPanel.get().add(demo.panel);
Any ideas?

How can I integrate things like the twitter 'tweet button'?
Basically, I want to use something like this:
https://twitter.com/about/resources/buttons#tweet
I found this page which suggests loading the script at the beginning, then
using jquery to look for certain elements and then renders relevant
elements:
http://thegregstier.blogspot.com/2011/05/facebook-and-twitter-buttons-in.html
I also found this code:
.
final String scriptStr = !function(d,s,id){ + var
js,fjs=d.getElementsByTagName(s)[0];
+ if(!d.getElementById(id)){ +
js=d.createElement(s);
+
js.id=id;js.src='//platform.twitter.com/widgets.js';
+ fjs.parentNode.insertBefore(js,fjs);
+ }}(document,'script','twitter-wjs');;
final ScriptElement scriptElement = Document.get().createScriptElement(
scriptStr);
// we place the script just after the body tag
bodyElement.appendChild(scriptElement);
Any suggestions? I want something simple and clean. Thanks.

Re: right-to-left
Have you tested that by adding a locale into your .xml module file? You can add the Arabic locale like this: extend-property name=locale values=ar / Then when you change the locale you would find that GWT does rearrange the widgets as a mirror-image, so if you have a horizontal panel with a label on the left then a text box on the right, after switching to a RTL locale the label would be on the right and the text box on the left, all done magically for you by GWT.

Re: instance or class?
I thinks it would be better if you included snippets of your code so it's
clearer for anyone wants to help you. You seem to be concerned with
creating and maintaining classes, however, GWT does a lot of clean up for
you, so when you call rootPanel.clear() GWT will detach all of it's widgets
and clear the memory for you AFAIK.
Don't think too much about performance and optomisation at the moment.

The first screen (class) is an instance object because that is the way
GWT spawns it (probably for good reason to support other models). For
my remaining screens I just use class methods and class variables
instead of creating an instance. I do this for two reasons. The main
reason is that I don't have to keep track of which instance when I do
things with the screen. I would only have one copy of the screen.
I presume that if I opened the same app in another browser tab it
would be entirely unrelated to the first tab. It would be like
starting up two copies of the same program. One has nothing to do
with the other. And, of course, one machine would have utterly
nothing to do with the other.
This all makes sense in theory and seems to work fine while debugging
under eclipse. However, when I started it up under glassfish in a
production environment, my app is flaky. Sometimes I enter data,
click a button, and nothing happens. Other times a new screen is run
and no data (from the server) shows up. When I retry it it works. I
don't know what is causing this but I thought perhaps my unorthodox way
of switching screens might be the problem.
So, I have two issues. The first issue is whether I can do things with
classes and resetting the root each time or not. The second is - what
is causing the flakiness when operating in a production environment?
Any pointers would really be appreciated.
Thanks.

Re: Serialization help
Any object that is sent/received via RPC has to adhere to the serialization policy: https://developers.google.com/web-toolkit/doc/1.6/DevGuideServerCommunication#DevGuideSerializableTypes So, Subtype has to be Serializable. On ther other hand, if you only want to get Subtype, then just declare that in your service and forget about the Type if you never going to receive it. -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: Facebook login button
I don't think that Scribe is gwt safe, so what I did is handle most of the login process on the server side. Unfortunately, I couldn't find easy tutes for that. Most importantly you have to understand how OAuth works (which is easy especially v.2). Then try to implemented yourself, here are a few pages that may help you: https://code.google.com/p/gwt-examples/wiki/DemoGwtGData http://stackoverflow.com/questions/8991955/doing-oauth-with-scribe-for-gwt There's a complete sample project for OAuth with GWT: https://code.google.com/p/gwtoauthlogindemo/ But the code is bad and confusing, I found out that the process is easier than portrayed by this project. -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

User login and session management.
I'm implementing a simple app which require users to be logged in for some pages/actions. I get the idea about sessions and cookies, and after some reading I deduced that the best way is to only save the session id on the client side as a cookie. Then all communication with the server (that requires users validation) will be done by this session id. The issue here is that sessions expire, some noted to user a timer on the client side to rest the sessions duration. But what if the user is inactive for a long time, *does that mean that the user has to login if the session has expired*? I know that sessions duration can be extended, but I don't reckon this is a good idea, or is it?

Re: Facebook login button
You can check this page on facebook: https://developers.facebook.com/docs/facebook-login/getting-started-web/ You probably have to use OAuth protocol for that.

java.lang.RuntimeException: Unexpected failure when returning from an RPC call.
I'm having this sudden and strange issue, when my RPC call tries to return
the value, this exception is thrown:
java.lang.RuntimeException: Unexpected failure
It happens at this code of the GWT library:
/**
* Creates a new instance of {@code klass}. The class must have a no-arg
* constructor. The constructor may have any access modifier (for example,
* private).
*/
@SuppressWarnings(unchecked)
public static T T newInstance(ClassT klass) {
ConstructorT c = (ConstructorT) constructorCache.get(klass);
try {
if (c == null) {
c = klass.getDeclaredConstructor();
c.setAccessible(true);
constructorCache.put(klass, c);
}
return c.newInstance();
} catch (Exception ex) {
throw new RuntimeException(Unexpected failure, ex);
}
}
I emptied all and every cache I can think of, I also started using JDK 6
instead of 7, but with no luck yet.
I'm using GWT 2.5.1 and App Engine 1.7.7.1.

Re: Can I use DI in widget cells,because it doesn't seem to be working with me?
Good question, I don't even know how they are instantiated!
I just got a CellList declared as:
private final CellListPresentable cellList = new CellListPresentable(new
TileCell());
and call this method to update the list:
public void setTilesStartingAt(int start, ListPresentable tiles) {
cellList.setRowData(start, tiles);
}
How are they instaniated, sorry I just started learning about cells.

You can use DI everywhere object creation can be done by the DI container (for
instance, it means using @UiField(provided=true) or @UiFactory for UiBinder).
So the question is: how are your cells instantiated?

Thumbnail interface with infinite scrolling, are cell widgets the best choice?
Hi, I'm writing an app which has a thumbnail interface and in which users may want to browser hundreds if not thousands of custom widgets (images + other). Are data presentation widgets my best choice?

Re: Is there a set of best practices for implementing nested presenters/view?
Yeah, I don't have any intentions in using any more frameworks. Let me ask you this, let's say that you have a page which has multiple panels and in each panel there are multiple widgets. How would you go about implementing that yourself? I'm especially interested in the case that you wanted for some of these widget to communicate with each other. In my design, I made a 'father' presenter that has a few 'children' presenters, the idea here is that these presenters can communicate with each other directly (father to children and vice versa), with the father having the overall control. Of course, each presenter controls its own view and nobody knows about this view. Isn't that a good way of handling things or is it complicated?

Re: Is there a set of best practices for implementing nested presenters/view?
Wow, that's a lot to digest, I need some time for that. Thank you very much. Just a quick Q, controllers, views, presenters and facades are all different things? Also, wouldn't you consider facades a form of presenters? If not then what is the difference? I really like your input and hope more people contribute to this discussion.

The component has a Controller, View, if required a Presenter and always a Facade. The facade hide's all internal things and is the class that others use to communicate with the component. This setup has many advantages like clear, pushing events instead of pulling to overcome a Handler web that results in memory leaks, good unit testable as all required things like presenter, controller, view, widgets... etc.. are created through the facade and the facade is mocked through the GWTBridge during unit testing. + All controllers are lazy loaded through code splitting and hold in a central controller storage. + The View composes widget, not more, not less and take care that it keeps this responsibility during development as developers often put too much widget things in a view such that the view's become messy and hard to test. + In the View you use hardcore OO design and use things like HeaderPanel, ProductContainer, Product, StatusButton, etc... I can't stress enough the OO design, as if you do, you will see that flow's and coding becomes logic and stays maintenable such that it's easy and natural to add functionality. Yes, you probably complain that you get a lot of small objects, and the code often takes longer to understand, but that's OO, but the advantage of optimal reuse of small pieces of functionality. + Use standard patterns like factory, singleton, visitor, service, builder patterns, such that others can more easily understand the code. + Use lightweight widget (builders) that extend from IsWidget (ProductContainer extends from IsWidget), that contains logical and can easily be tested. + If these widget (builders) need to communicate with eachother I use a Communicate interface (or Informer interface) that is public but contained in the Widget itself. I't s usualy injected throug the constructor and required. + The Composer (father in your story) implements mostly all Communicator interfaces and delegates it to others, like: bubble it up to the controller, or let another widget do something. It all depends on the responsibility of every widget/component. For example: in my case, only the controller is allowed to communicate to the backend, such that only the controller contains Async callbacks. + Use a lot of Characteristic interfaces like HasId, HasEmpty, HasSize (just like GWT does), as this makes coding a lot easier as the Communicators are basically composed of these smaller interfaces... + The number of if conditions and static methods is a measurement for your OO coding. The more if statement, and static method usage, the less your are coding OO (this comes from the OO books). Anyway: I often use Singleton classes instead of static utility classes. The nice things of these singleton classes is that you can change their implementation through deferred binding. Example: CmsKeyNames that contains all cms keys, or CmsFactory (factory pattern). Too often I started with static methods and then needed other return value's under certain conditions (other app), which is hard when using static method as you can't do anything with it.. Changing them can be a pain. + etc Yes, it all results in more coding... but that's why people often complain that Java is a very verbose language ;) Especially when you want to correctly code OO. Above setup is especially friendly for long running app's that need to be changed in such a way that it stays maintenable and changes don't become too expensive. Above just came up, which I think contains some things you can use. Good luck.
