Immutable object from the business layer
My current project has been struggling lately with the use of immutable objects and/or properties of objects from the business layer. I wonder how common this is and interested in any recommendations. The project is divided between our group, which makes the UI with GWT (and Ext GWT, aka GXT), and a remotely located group that develops the business layer. The business layer defines domain classes such as entities etc. that we generally refer to as DTOs (not the best name, I think, but that's another story). So, for example there is a DTO called OrderDTO which has a list of LineItemDTO. You get the idea. These DTOs are generally not GWT-serializable so the UI has to create parallel objects which are (GXT ModelData types we call MDOs), and translate between the DTOs and MDOs. The whole need to have translated objects is a pain, but that too is another story, so let me get to the point. The DTOs lately have been modified to have immutable properties. For example, the OrderDTO's ID and dateOrdered properties might be immutable. This seems like a good idea to the business layer developers but causes the UI headaches since it makes it harder to do the MDO-to-DTO translation. Still, that's not too bad since it tends to be a constructor call with arguments for immutable properties. But it gets worse, IMHO. The business layer now also wants to put properties in the DTOs that must still be in the DTO when sent back to the business layer. That is, the DTO must be held and sent back as the same instance. This creates a real problem because the UI must hold the DTO on the server and then be sure to use the same instance for updates (etc.) instead of simply making a new instance based on properties from the MDO. This kind of use of immutability is forcing us to bring server-side caching into the UI design, not for performance, but for storing DTOs. I'd much prefer to have state in the UI only be in the browser while keeping the server-side essentially stateless. But I'm not sure if I'm in the norm or if the business layer folks are. What to you think? Many thanks in advance, boz ps: I'm not against immutability. Generally I think it's a good thing. But is it right in this context? -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Using DialogBox with UIBinder
Hi everybody, referencing to http://groups.google.com/group/google-web-toolkit/browse_thread/thread/28e24ea25dd8e3a2/3c6fcec9e65049d3?#3c6fcec9e65049d3 I'm encountering the same issue with the subclassing solution. I found out that it's based on the way the different parsers are used by the UiBinderGenerator. For subclasses of DialogBox the DialogBoxParser sets the initializer to new DialogBox() and later on the BeanParser scans the owner bean, finds the @UIFactory method and tries to set it as the initializer. Did anybody find a solution beside writing a wrapper around the DialogBox as suggested in solution 2? -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: AsyncCalls
The async interface usually has a void return type, but it can optionally
return a Request object, like this -
import com.google.gwt.http.client.Request;
interface MyServiceAsync {
public Request myMethod(String s, AsyncCallbackString callback);
}
So, after you make your Async call, hold on to the Request object. When you
wish to cancel the calls, invoke the request.cancel() method.

RPC Endpoints and threads
Hi All I've been thinking a lot about the GWT RPC mechanism and from the tests that I've done it appears that the same endpoint instance is used for every RPC call. So presumably if you've got a hundred users all making the same RPC call all at the same time there are 100 different threads trying to access the same object. Is that correct? Just having written that, another thought occurs that I haven't checked for, is it just that the same endpoint object is used for a session? So different users, who obviously have different sessions, get their own endpoint object? Anyway, assuming I was right the first time and an RPC endpoint is shared by all sessions, has anyone considered pooling endpoints and serving them up per session like I believe EJB does? -- Thanks Paul Paul Grenyer e: paul.gren...@gmail.com b: paulgrenyer.blogspot.com -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: UIBinder and CSS resources obfuscation
Yep, I know the @external does the trick, but I was wondering if it
exists some kind of global '@external' annotation to tell UIBinder not
to obfuscate all classes.
@Jeff Chimene : I think you right.
My fear is that the UIBinder has to keep this kind of obfuscation/
renaming rules to garantee the non collision in css class name.
But, what can't we imagine an option to not obfuscate css classes and
raise an error when a collision occured ?

Re: UIBinder with code in earlier versions of GWT

Re: RPC Endpoints and threads
Servlet containers typically make only one object of your Servlet. This object is shared across several threads. Several threads is a configurable property on most servers, but usually varies between 15 to 30. If you have 100 users connecting simultaneously, the server will not start 100 threads - the remaining requests will be queued. But multiple threads sharing the same Servlet (or end-point, as you put it) object does not *usually* matter. That is, if you follow servlet best practices. The GWT RPC Servlet is Stateless. Even if 1000 users access it at the same time, it is OKAY - they will not interfere with each other. When you write a RPC Servlet extending RemoteServiceServlet, you should also ensure that it is stateless. There are several ways to do it, but the easiest is to *NOT use member variables in your ServiceImpl*. Users in different sessions are also serviced by the same Servlet object. It is up to you to handle them differently by reading from the Session object and taking a different action for each user. And, just to go a step further, the recommended approach is to not use sessions. That gives you opportunities to scale later. EJB's are a complicated beast and meant to solve an entirely different class of problems. Even if you already use EJBs in your project, you should still write a RPC Servlet that delegates the heavy-processing to EJB. --Sri On 15 April 2010 13:19, Paul Grenyer paul.gren...@gmail.com wrote: Hi All I've been thinking a lot about the GWT RPC mechanism and from the tests that I've done it appears that the same endpoint instance is used for every RPC call.

markup and i18n/Messages
What is the best plan for allowing/disallowing markup in i18n messages? I'd be tempted to say no but one day the pointy haired boss is going to say he wants a word in italics and I'd feel a bit silly saying no. Sorry if I've missed something but does GWT offer a solution to this? The best I can think of is that by default messages won't have markup (so will be escaped) but if the message starts with a valid tag e.g. span then I will turn off escaping for at least strong, em etc... So not very good at all. Thanks Sam -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

In other words, I thought that: g:VerticalPanel g:HorizontalPanelg:LabelLine 1/g:Label/g:HorizontalPanel g:HorizontalPanelg:LabelLine 2/g:Label/g:HorizontalPanel /g:VerticalPanel would give the same result as: g:HTMLPanel table tr tdLine1/td tdLine2/td /tr /table /g:HTMLPanel But in the first case, it generates this Java code: com.google.gwt.user.client.ui.Label f_Label3 = (com.google.gwt.user.client.ui.Label) GWT.create(com.google.gwt.user.client.ui.Label.class); com.google.gwt.user.client.ui.HorizontalPanel f_HorizontalPanel2 = (com.google.gwt.user.client.ui.HorizontalPanel) GWT.create(com.google.gwt.user.client.ui.HorizontalPanel.class); com.google.gwt.user.client.ui.Label f_Label5 = (com.google.gwt.user.client.ui.Label) GWT.create(com.google.gwt.user.client.ui.Label.class); com.google.gwt.user.client.ui.HorizontalPanel f_HorizontalPanel4 = (com.google.gwt.user.client.ui.HorizontalPanel) GWT.create(com.google.gwt.user.client.ui.HorizontalPanel.class); com.google.gwt.user.client.ui.VerticalPanel f_VerticalPanel1 = (com.google.gwt.user.client.ui.VerticalPanel) GWT.create(com.google.gwt.user.client.ui.VerticalPanel.class); f_Label3.setText(Line 1); f_HorizontalPanel2.add(f_Label3); f_VerticalPanel1.add(f_HorizontalPanel2); f_Label5.setText(Line 2); f_HorizontalPanel4.add(f_Label5); f_VerticalPanel1.add(f_HorizontalPanel4); and the second case, it generates: com.google.gwt.user.client.ui.HTMLPanel f_HTMLPanel1 = new com.google.gwt.user.client.ui.HTMLPanel(table tr tdLine1/td tdLine2/td /tr /table); So am I right to think that I should never use widget inside UiBinder xml except if I have the attribute ui:field (in other words, except if I need it in the Java code)?

Re: UiBinder performances: widgets without ui:field still instantiate?
I don't know if you're right about thinking that there's still situation where an HTMLPanel or layout panel, without uifield is the best way to go, but I do know that we should use as often as possible html code instead of widget for the very reason you exposed. BUT I'm still wondering if once compiled to JS those instanciations are translated to plain html. It's not clear in what you're saying if it's in production or in development mode.

Re: Making a simple 3 column layout?

You can find the tutorial here: http://blog.discovr.net/post/516021390/layout-your-app-using-gwt-2-0-the-way-you-want-it We built this tutorial using UiBinder, so it should be straightforward for you.

Gwt 2.0 with Symfony php framework
I must implement a web application using Symfony php framework (with doctrine) with a javascript framework in order to use and create rich UI components. First of all, I have to realize a study of existing javascript framework and I must choose one. GWT provides many UI components and has many advantages compared to other traditional JS Framework (designer, developped view in java, ...). However, I don't find complete tutorial about the use of GWT with php or Symfony (except http://examples.roughian.com). I would like your opinion, Is a Symfony project using GWT is viable?

Re: Switch RootPanel with RootLayoutPanel
I'm having a similar issue. I have widgets added to elements using RootLayout.get(foo).add(widget) but then want to add a Panel on top using RootLayoutPanel.get().add(layout). that's all fine, but removign the LayoutPanel leaves somethign behind that means the widgets on the page cannot be clicked.

Re: UiBinder performances: widgets without ui:field still instantiate?
So am I right to think that I should never use widget inside UiBinder xml except if I have the attribute ui:field (in other words, except if I need it in the Java code)? Its best to minimize usage of widgets when you can; there is always a cost associated with them. Specifically, VerticalPanel and HorizontalPanel almost always should be replaced with divs (or tables if you don't like semantic markup). BUT I'm still wondering if once compiled to JS those instanciations are translated to plain html. It's not clear in what you're saying if it's in production or in development mode. The code pasted was the intermediate, unoptimized java code that uibinder generates prior to java - js compilation. It will undergo optimizations once the compiler acts on it, and the code will for sure be a lot more performant. However, in general, innerHTML is much better performance wise than creating objects and adding them to DOM. So, even after the compiler finishes all optimizations, performance wise it will still lag behind inline html. --Sri On 15 April 2010 19:30, Christian Goudreau goudreau.christ...@gmail.comwrote: I don't know if you're right about thinking that there's still situation where an HTMLPanel or layout panel, without uifield is the best way to go, but I do know that we should use as often as possible html code instead of widget for the very reason you exposed.

Re: markup and i18n/Messages
Hi, There is a big risk in using markups in properties files. They are likely to go to a translation office were the people don't know about markups. May be they translate strong to stark. You could never be sure, that these markups apply at all. Depending were you insert it, your markup is taken literally. Both approaches will produce earlier or later massive testing costs. When application is display a longer text where some words are marked, I would consider to use ClientBundle TextResource or ExternalTextResource.

Re: UiBinder performances: widgets without ui:field still instantiate?
Thanks for your help. I guess, even after java - javascript compilation, the first example will still instantiate a javascript object for each widget, right? So am I right to think that I should never use widget inside UiBinder xml except if I have the attribute ui:field (in other words, except if I need it in the Java code)? Its best to minimize usage of widgets when you can; there is always a cost associated with them. Specifically, VerticalPanel and HorizontalPanel almost always should be replaced with divs (or tables if you don't like semantic markup). BUT I'm still wondering if once compiled to JS those instanciations are translated to plain html. It's not clear in what you're saying if it's in production or in development mode. The code pasted was the intermediate, unoptimized java code that uibinder generates prior to java - js compilation. It will undergo optimizations once the compiler acts on it, and the code will for sure be a lot more performant. However, in general, innerHTML is much better performance wise than creating objects and adding them to DOM. So, even after the compiler finishes all optimizations, performance wise it will still lag behind inline html. --Sri On 15 April 2010 19:30, Christian Goudreau goudreau.christ...@gmail.comwrote: I don't know if you're right about thinking that there's still situation where an HTMLPanel or layout panel, without uifield is the best way to go, but I do know that we should use as often as possible html code instead of widget for the very reason you exposed.

Re: Switch RootPanel with RootLayoutPanel
Hi, I've figured out that you need to remove the RootLayoutPanel from the RootPanel. You can do this with RootPanel.get().remove(RootLayoutPanel.get()), or RootLayoutPanel.get().removeFromParent(). Note that this means that the singlton RootLayoutPanel returned from RootLayoutPanel.get() will no longer function as it does not get reattached. You can work around this by reattaching it to RootPanel with RootPanel.add(RootLayoutPanel.get()); It would be better if RootLayoutPanel.get() always ensured that it was attached to RootPanel.get() before returning. It is also nto very obvious to a newbie (like me) that simply having RootLayoutPanel attached will block clicking on anything attached to the RootPanel. While it is perhaps uncommon for this to occur simply by calling RootLayoutPanel.get(), a moer common scenario would be adding a LayoutPanel to the RootLayoutPanel and then removing it. This leaves the RootLayoutPanel still attached, bu the underlying RootPanel inactive. Wouldn't it be a good idea to automatically detach the RootLayoutPanel if all of it's children are detached?

Re: Help with DockPanelLayout and UIBinder - Not able to bind field names
When you call uibinder.createAndBindUi(this), it creates HTMLPanel
instances as defined in your template and assigns them to your fields.
This overwrites the instances you created manually. There are 2 ways
to fix this:
1. Use the HTMLPanel instances that UiBinder creates and add your
content to them after calling createAndBindUi.
2. If you really want to create the HTMLPanel instances yourself (or
inject them via constructor arguments), you can mark the fields with
@UiField(provided=true). I'm not sure if it matters whether the fields
are set before or after calling createAndBindUi.
Given the choice between the two, I would generally favor #1, and I
think that's closer to what you're trying for anyway by calling them
containers. Let UiBinder create the containers that you can then
fill with anything you want.

Hi,
Am trying to create a simple DockPanelLayout for my applicaiton.

This is the Owner class:
public class Application extends Composite {
@UiField
public HTMLPanel headerContainer;
@UiField
public HTMLPanel centerContainer;
@UiField
public HTMLPanel footerContainer;
interface ApplicationUiBinder extends UiBinderWidget, Application {
};
private static ApplicationUiBinder uibinder = GWT
.create(ApplicationUiBinder.class);
public Application() {
headerContainer = new HTMLPanel(bHeader/b);
centerContainer = new HTMLPanel(Center);
footerContainer = new HTMLPanel(Footer);
initWidget(uibinder.createAndBindUi(this));
}
}
And this is what I do in EntryPoint:
Application app = new Application();
RootLayoutPanel.get().add(app);
I dont get the labels - center, header and footer in the page.
On debugging I found that output generated by createAndBindUI contains
empty divs (while the inner html is expected).
Any help in this regard will be appreciated.

So, after you make your Async call, hold on to the Request object. When you

You'd better issue the first request after a short delay (150ms for

Re: How to put same widget under multiple tabs in TabLayoutPanel?
thanks, this sound like an idea.

Rounded Corners with UIBinder
Despite all my searching (and mostly because of the limited
information available regarding proper use of UIBinder) I cannot find
a simple, elegant way to use UIBinder with rounded corners. The
Google I have a vary simple, one page business card site with the with
the outline of the page as a rounded corner pod. There are a few pods
within that, one of which I want to use as the new TabLayoutPanel
(requiring strict browser support). I considered using the older
DecoratorPanel but that requires quirks mode. Is there an equivalent
for the new layout structures? My original code just laid out css
in the default html page and I anchored all my widgets using the
RootPanel.get('id') operation but that does not work with
RootLayoutPanel.get(), thereby limiting my ability to use the new
TabLayoutPanel.
I'm considering avoiding the new UIBinder features altogether, at
least until more tutorials are available but I have to say I'm am very
tempted
I hope this all makes some sense. I'd be happy to clarify as this
simple webpage project in GWT has turned into much more of a design
barrier than anything else.

Re: GWT Problem
I'm not sure I follow why you have to get it from the div. If you don't, could you just use myTextBox.getText()?

Re: Rounded Corners with UIBinder
It's not the best, because it only works on Mozilla and Firefox, but the

Re: Rounded Corners with UIBinder
If gwt has a failing it's making the app look well rounded. Ok bad
pun. The uibinder makes you think you are sculpting a ui. You really
aren't. You are writing a skeleton that needs CSS for the flesh.
The client side generated HTML is complex which makes the task harder.

Although I can't wait for css3 to be widespread, too many people still

Re: Rounded Corners with UIBinder
So given that CSS is used for the flesh what to you anchor it to?
The layout panels? With images as backgrounds (so you'd need 4
different anchors for 4 rounded corners?)? Or do you use something
like an HTMLPanel with several divs to outline around layout panels?
I feel more and more like my code is becoming a hodge-podge of
different markups and losing some of the benefits of the simplicity
of UIBinder. It seems like I'm missing a more elegant solution.
Anyone?

[gwt-contrib] PopupPanel.show() can enter an invalid state if attached (issue298804)
Reviewers: Lex,
Description:
If a PopupPanel is attached to a Panel, calling show() will put it into
an invalid state where it is physically and logical attached, but its
isShowing boolean is set to false. Once in this state, it cannot be
hidden.
Fix:
When show() is called, we now check if the PopupPanel is attached (and
not showing) and remove it from its parent if it is.
Testing:
