Prototype call failes using JSNI with GWT
Hi all,
I've the following code:
public final native JavaScriptObject addNode(...) {
...
outputPort.createCommand=function(request) {
alert(request);
$wnd.draw2d.OutputPort.prototype.createCommand.call(this,
request);
alert(done);
}
...
}
When the function is called, [Object] will be promted. After that, an
JS-Error occurs: undefined is null or not an object.
It seems to be that the parameter request is not submitted to the
underlaying function. If I uncomment the function
outputPort.createCommand=function(request)... it works very well.
The variable outputPort is an instance of draw2d.OutputPort and
draw2d.OutputPort contains the function createComment(request).
I've done this with oder functions without parameter and it works...
Any ideas?

Any plans for UIBinder to allow custom parsers?
For users of SmartGWT, or any other highly customised GWT framework, you might say that we should let them develop their own xml ui definition strategy. To preempt any possibility that UIBinder architects might remotely have such an attitude - I would say that attitude, if existent, is wrong. Wrong because - that would cause all of us to vacillate across a few ui xml conventions within the same project. - it would miss the opportunity to provide the whole gwt community with a unified convention as jsp and jsf had been for the jee community. Now, that I think I have somewhat successfully preempted anyone from thinking each to his/her own ui xml strategy, comes the actual question. What are any plans for implementing strategies for UIBinder to allow custom widgets? The current situation for UIBinder is untenable, - due to the reliance on individualised element parsers - the inability to stick my own parser into gwt compilation process For example, - I cannot define my own widget hierarchy like menubar or tabbar can, with pseudo-elements like tab, header, directions, etc - I cannot define a custom widget that effectively implements both HasWidgets and HasHTML. If my custom widget implemented HasWidgets with either HasHTML or HasText, the uibinder parsing part of gwt compiler seems to ignore HasHTML and HasWidget and barfs at me for having forbidden html nodes or text. (Is this a bug or a feature?) There should be a plan and strategy, perhaps by programmers supplying a DTD to signify the allowed nodes and the DTD is compiled with the parser java code. i.e., a gwt element-parser compiler. So, any plans for a gwt element-parser compiler? -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: RichTextToolbar in Uibinder
Ok,
taking a look at the RichTextArea in showcase
http://gwt.google.com/samples/Showcase/Showcase.html#!CwRichText
it looks like in order to get the toolbar you need to use
RichTextToolbar and give it the area.
// Create the text area and toolbar
RichTextArea area = new RichTextArea();
area.ensureDebugId(cwRichText-area);
area.setSize(100%, 14em);
RichTextToolbar toolbar = new RichTextToolbar(area);
toolbar.ensureDebugId(cwRichText-toolbar);
toolbar.setWidth(100%);
As one widget will require another one, this will probably help:

Re: new GWT MVP article (part 2)
I'm trying to figure out how to make this parallel composite views / presenter hierarchies. And in my opinion it just break the MVP pattern. One of the goals you pursuit with MVP is to decouple the View object from the logic it contains (the presenter). Making the Presenter unaware of how the view is actually rendered. And also implicitly by using the EventBus decoupling the presenters from the others. In the moment you have a 'parent' presenter, everything screw up: 1. The parent presenter has a knowledge of the children presenters. You may be attempt to move the logic relating the children (before in the event bus) to the parent presenter. Coupling them unnecessarily. 2. Worst. The parent presenter has good knowledge of the view he manages. The view needs to provide hook for the children. So the presenter can attach the views of it child presenters to it. Of course, it may be cases where having a 'Parent presenter' is a good idea. But I think of this cases where actually you make the separation for no conceptual issues (be able to reuse code, like you could do in a table, separating the rows as views). Maybe I misunderstood something here. But I think the 'guy' responsible for the layout can be the AppController. As in the first first part of the article states. 'The AppController is responsible to handle logic that is not specific to any presenter.' But I don't like to much the idea. It makes the AppController aware of the view and layout. But on the other hand it may make sense, he is already aware of the History tokens. And probably if you are also deploying for mobile devices you will end up you need to rewrite the AppController. Other idea I kind of like more. Is using this new concept of Activity (Google IO 2010, Architecture GWT) So each activity will be a page in the application. The AppController is listening the EventBus for events requesting a new Activity. Then the AppController load the new Activity and tells it to display the page. So basically splitting the AppController into Activities. What do you think about this? Are this parent presenters a good idea. Better to move them to other 'entities' like AppController or Activity?

Chris, I was wondering if you can share any code samples, or if possible ask google team to write a tutorial on more complex layouts and navigation. (parent/ child, composite views). I've visited many forums, and this has been an area where many are struggling. TheMVPtutorial is great for introducing the concepts, but for real world applications with complex layout, i think more examples/ resources are definitely helpful for those who want to follow best practices. almost all GWT books are written prior to 2009, mainly dealing with widgets, and very little on architecture, especiallyMVP.

Re: Problems releated to javaMail in GWT application
One of the biggest concepts to get your mind around with GWT is that while you develop everything in Java, in the end the GWT compiler converts your Java into Javascript (mostly, but some CSS HTML too). So when you create a Java class called foo.java, what will result is something like foo.js. So if in foo.java, you use java.lang.String, you think you're using the one in the standard Java JRE. But you're not. What GWT has is a large set of JRE emulated classes, written in Javascript. So the compiler knows how to convert java.lang.String into something appropriate to run in a browser. So in foo.java, you do what every good Java developer does and import something like javax.mail.Message and so on, and crank out some beautiful code. And you then ask the GWT compiler to convert that into Javascriptand it can't. It has no idea how to do javax.mail type of things in a web browsermostly because it can't. The browser is a heavily constrained runtime environment and things like filesystem access, port/packet operations (which I believe javamail does down in the bowels), data access, and whole bunch of other Java stuff can't be done in Javascript, in a web browser and therefore GWT can't do them on client. The only way to achieve this is to build a GWT client that communicates with a GWT server (preferably with GWT-RPC, but that's your call) where you can run full fledged Java and are not bound by the issues inside a web browser. I write this a lot, but it's worth mentioning again: this is not a limitation per se of GWT...all web browser based clients that run natively in Javascript are bound by the same security rules. Plugins like Flash, Silverlight and Java Applets are outside of this control umbrella. The amount of Java that is emulated in Javascript by the GWT compiler is staggering, but not infinite... Hope this helps. Later, Shaffer On Jun 4, 11:57 am, samounas elmokhtari.as...@gmail.com wrote: Please can you tell me how to use javaMail in gwt application.

An example Place Service(Activity Manager) implementation maintains complex dependency between presenters in MVP
When I looked at MVP related articles, demos and so many
implementations, I keep ask myself following questions.
(1) How to make Place definition simple yet flexible?
(2) How to elegantly decouple presenters and decouple a presenter and
it's container and it's children presenters?
(3) What is the responsibility of Place Service (or Activity Manager
in GWT2.1)? and what does the API look like?
Since I struggled so long to try to find the answers, I'd like to
share what I got so far (I've written a Place Service implementation).
My own humble opinion regarding these questions are:
(1).
Most of time, place can be just a string but some times it need to
carry parameters or even extend from other places. Therefore, a Place
should be an interface instead of concrete class so enum can be used
to define simple static places.
public enum Pages implements PagePlace, GenericPlace {
HOME, HELP, SECURITY_PERMISSION, SECURITY_ROLE // ...
@override
public String getHistoryToken() {
return name().toLowerCase();
}
}
There are places which carry history tokens but some are not, for
example, header and footer of application are places but does not
require history token.
public enum CommonComponents implements ComponentPlace {
ROOT, HEADER, FOOTER, TOPMENU, SUBMENU, HELPCENTER, MAIN
}
For the places need to carry a parameter, it'll need to be defined as
a class instead of enum.
public class IdentifiablePlaceExample extends IdentifiablePlace
implements PagePlace, GenericPlace {
// Runtime place instance will use this constructor to create
place with identifier
public IdentifiablePlaceExample(String identifier) {
this.identifier = identifier;
}
// Return history token for Browser - #!(token):(identifier) will
be displayed in browser url
@Override
public String getHistoryToken() {
return history-token-you-want;
}
}
(2).
In my opinion, a presenter should NOT attach the corresponding view to
DOM or a container presenter itself.
public interface Presenter {
public Viewable bind(Place place);
public void unbind(Place place);
}
public interface Container extends Presenter {
public void showChild(Place place, Viewable childView);
public void closeChild(Place place, Viewable childView);
}
In my Place Service implementation, Place Service knows the dependency
between presenters but not presenter themselves. Therefore, when a
view been required, Place Service will call the Presenter.bind(Place
place) function to ask the corresponding Presenter to provide a View
instance.
After that, Place Service will find out which Container (a special
type of Presenter) is responsible for displaying that type of Place
and call Container.showChild(Place place, Viewable view) function to
let the Container handle displaying the view in the container view.
E.g. display a particular tab page (The View returned by the
Presenter) in a tab container (The Container presenter).
This way, in my main presenter which handles multiple children pages
will no longer need to know any of other presenters but a generic
Place type.
public class MainPresenter implements Container {
@Override
public void closeChild(Place place, Viewable childView) {
view.getPageContainer().remove(childView.asWidget());
}
@Override
public void showChild(Place place, Widget childView) {
if (place instanceof PagePlace) {
view.getPageContainer().add(childView.asWidget());
}
}
}
(3).
Besides controller simple presenters, a Place Service should provide
automatic (invisible to Presenters) bind/unbind support to complex
dependency graph. E.g.
Root (C)
- Header (P)
- PageContainer (C)
- Login (P)
- Main (C)
- Page1 (P)
- Page2 (P)
- Page3 (P)
- ...
- Footer (P)
To build this kind of complex graph, I've created a Place Binder to
simplify configuration and used a GIN module to centralize them.
// setToRoot is a special function to let place service know when to
stop scanning.
bind(root).serve(Places.ROOT).setToRoot().contains(Places.Header,
Places.PageContainer, Places.Footer);
bind(header).serve(Places.HEADER);
bind(pageContainer).serve(Places.PAGE_CONTAINER).contains(Places.Login,
Places.Main);
// setToDefault make the current presenter default entry of
application (If history token is not specified by user)
bind(login).serve(Places.LOGIN).setToDefault();
// contains function can take a Place class type instead of specific
instance, this way any Place extends PagePlace will be handled by
MainPresenter.
bind(main).serve(Places.MAIN).contains(PagePlace.class);
bind(page1).serve(Pages.PAGE1);
bind(page2).serve(Pages.PAGE2);
bind(page3).serve(Pages.PAGE3);
bind(footer).serve(Places.FOOTER);
After configuring the graph, we can navigate to any HistoryPlace
through Place Service API or
GWT2.1 M1- Issues with KeyPressEvent and registering the Enter key pressed
Hi
I just updated to GWT 2.1 Milestone 1 build and after that I am having
problems with registering the Enter key pressed in a text box.
If I have the following block , it never enters it.
if (event.getCharCode() == KeyCodes.KEY_ENTER) {
// DO SOMETHING IN HER
}
I tried printing out the event.getCharCode() when the ENTER KEY is
pressed and all I get is a blank String.
Was this changed on purpose or is this a bug ?

Hello, I am facing pretty much the same problem and I thought of using the g:Image tag but the thing is that I don't knot how many pictures I will receive (It's a gallery), and AFAIK there is no iteration mechanism in UI:Binder, so the only option is to manually manage this in Java code, right?

Prevent Selection of Image
Hi, I've got several Image Widgets on my Site. Is there a way to prevent the selection with the mouse? Selection of an image means its getting a blue background and being draggable to other windows. Can you think of an HTML or GWT solution? I read that one option was to add an mouseMove event handler and let it return false;. This was a pure JavaScript solution, not related to GWT.

Re: Root Panel
You should not use RootPanel in the UiBinder. You need to use any of the types extending SimplePanel or LayoutPanel. RootPanel and his equivalent RootLayoutPanel represents the BODY in the HTML page. At some point in the onModuleLoad() you need to have RootPanel.get().add(new MyWidget()); Take a look at: http://code.google.com/webtoolkit/doc/latest/DevGuideUiBinder.html for a guideline of how to use UiBinder.

Re: Prevent Selection of Image
Hi
Use div style='background: url(image.png); GWT can help you
writing this code.
http://code.google.com/webtoolkit/doc/latest/DevGuideClientBundle.html#Image_Sprites
Other option is to try to prevent the browser for taking the default
action. (I did not try myself)
image.addClickHandler(new ClickHandler() {
public void onClick(ClickEvent event) {
event.preventDefault();
}
});

can not set breakpoint (2)
Hi Everybody,
In GWT 2 Dev Mode, I can't make the breakpoints work in eclipse :
client app doesn't stop on any breakpoint.
My config is: GWT 2.0.3, Eclipse 3.4.2 + GWT Plugin 1.3.2, JDK
1.6.0_20. Firefox 3.6.3 (+ FF GWT Plugin)
As I suspected something wrong in the structure of my project in
eclipse, I tried with the GWT sample Hello.
Thus, after running ant eclipse.generate on Hello, I imported Hello
into Eclipse.
Here is an extract of the client code:
public void onModuleLoad() {
Button b = new Button(Click me, new ClickHandler() {
public void onClick(ClickEvent event) {
Window.alert(Hello, AJAX);
}
});
I put 2 breakpoints on lines Button b = ... and Window.alert...
I tried 2 ways to run the dev mode.
First way: select the file Hello.launch and then Run (Ctrl+F11). This
opens the GWT Development Mode shell.
Second way: In Properties window check the option Use Google Web
Toolkit, then select menu Run As Web Application. This opens the
Development Mode eclipse tab.
During both trials I could play with the application running into the
browser, and the breakpoints didn't worked in eclipse.
Does anybody could help me find what is wrong ?
Thanks
Yves

Authenticating User for GWT-Data (Contacts) in GWT App
Hello: I'm using the latest gwt-gdata package to allow users of my app (written in GWT) to access their Google contacts. But the problem I'm having is that when I check for a valid login using the User.login() method the package takes the user to a new page to authenticate/login and then I lose all state of my GWT application. So my question is this: Is there a way to do an in-app authentication that does not force the browser to go to a new site? If someone has some sample code illustrating this I would appreciate it.

RootPanel vs RootLayoutPanel
I'm new to GWT and trying to put together a simple login screen that
displays an alert window when the user presses the Login button. The
layout is done using UIBinder in a g:DockLayoutPanel. Which means
that my LoginWindow class has to be added to the RootLayoutPanel in
the onModuleLoad() function of my EntryPoint class:
public void onModuleLoad() {
DockLayoutPanel root = uiBinder.createAndBindUi(this);
RootLayoutPanel.get().add(root);
}
However, none of the @UIHandler functions get triggered. If I instead
add the LoginWindow to the RootPanel, nothing gets shown, but from
what I've read events should then work:
DockLayoutPanel root = uiBinder.createAndBindUi(this);
DockLayoutPanel root = uiBinder.createAndBindUi(this);
RootPanel.get().add(root);
}
Now, I may be missing something very simple, but I haven't been able
to find anything online that describes how to fix this problem. My
question basically boils down to, how do you enable event triggering
of UIBinder layouts with nothing in the RootPanel?
Thanks!
John

Re: Asynchronous callback
It's a servlet request, just like any other request. I don't think there is a tremendous amount of overhead ... the gwt framework just has to dispatch the request to the proper method and deserialize whatever you passed. Making a request is expensive in general, but I don't think rpc calls are substantially more expensive than any other request. What you do to compose the response could be expensive, though.

[gwt-contrib] Re: Fix issue 4423 - RPC ProxyCreator doesn't support methods with Type Parameters (issue575801)
With that new found information you have presented it certainly seems as
though it is a problem with the JDT as opposed to the proxy generator.
It seems to me the best solution would be to fix the JDT rather than fix
up my band-aid solution (which is not entirely correct).
Playing around further I have managed to narrow it down the the
following that produces the problem. The cause of the problem appears to
be in that the I type parameter references the O type parameter.
public class Broken implements EntryPoint {
static class InO {
}
static interface Interface {
I extends InO, O void method(I in);
}
public void onModuleLoad() {
final Interface impl = new Interface() {
public void method(final In in) {
}
};
}
}

Maybe we aren't really using 3.4.2, or maybe the fix really isn't in
there, or
maybe this is a new instance of that JDT bug. Further investigation is
needed to
see which.
Alternatively, we could generate type parameters. However, it requires
more
development of the patch. One thing is that the bounds on the type
parameters
need to be added. Also, what about type parameters of the enclosing
class? Those
would need to be handled as well. Using erased types means that all
these
questions go away, so it would be great if we can simply upgrade our
version of
the JDT to solve the problem.

Re: [gwt-contrib] Command pattern and GWT.runAsync
Does it really make sense to give all serivices the same intf. Im sure
because everything comes back to a big switch of some sort to dispatch the

does not exist.
If you really must batch pick the ones that actually belong to each other,
as they are a logical unit and sharing an intf makes sense.
The command pattern is for operations that are related its not intended for
each and every type of operation no matter how unrelated they are. GWT buys
you great type safety something one loses with Javascript and this uber

There are plenty of solutions to avoid a big switch statement. I'm
using a combination of inheritance and the visitor pattern to group
things.
By using annotations I can even build a repository of CommandHandlers

So why not ? Every application has the right for their design choices,
no ? Or can you give the ultimate approach that we all should be using

The initial problem only exists because of the introduction of a uber

groups. You alreAdy know there a always tradeoffs. In this case uber
cmd pat means code splitting can't work perfectly because of
reachability due to the command intf.

no ? Or can you give the ultimate approach that we all should be using
?
Yes and discussed above sometimes things don't alwyas work out
perfectly - that's life

Does it really make sense to give all serivices the same intf. Im

because everything comes back to a big switch of some sort to
dispatch the
different types of command results. With different end points this
problem
does not exist.
If you really must batch pick the ones that actually belong to each
other,
as they are a logical unit and sharing an intf makes sense.
The command pattern is for operations that are related its not
intended for
each and every type of operation no matter how unrelated they are.
GWT buys
you great type safety something one loses with Javascript and this
uber
command pattern throws all that out.

That way the exact problem described below is also avoided as an
added
benefit. Command pattern for browser apps is so struts and imho not
needed
for GWT RPC. After all what do you gain ?

Hi,
I am trying to split a GWT app that uses the command (action)
pattern.
The problem is that GWT.create(ActionService.class) causes
every
subclass of the return and parameter types to be included in the
initial fragment.
For instance, my action interface is:
public interface ActionService extends RemoteService {
T extends Response, V extends Request T execute(V req)
throws
ActionFailedException;
}
the problem is that module1.SomeRequest and
module2.OtherRequest
gets included in the initial fragment.
Do you see a way around this?
Thanks,
Julio Faerman

[gwt-contrib] FileUpload.setEnabled(false) causing invalid access of stack red zone 0x141055ff8 rip=0x101098a05
I'm seeing something fairly funky occur if I disable a FormUpload widget in a FormPanel.onSubmit() handler (here's the code: http://pastebin.com/SSSqGtB1). Basically the Dev server and browser crashes with the following console message: Invalid access of stack red zone 0x141055ff8 rip=0x101098a05 Running it with log=SPAM prints the following output over and over and over again until the crash: Invoke native method @com.google.gwt.dom.client.Element::setPropertyBoolean(Ljava/lang/String;Z) - this=JavaScript object(12) - arg[0]=string: 'disabled' - arg[1]=bool: true - return void Invoke native method @com.google.gwt.dom.client.Element::setPropertyBoolean(Ljava/lang/String;Z) - this=JavaScript object(7) - arg[0]=string: 'disabled' - arg[1]=bool: true - return void What's the expected behavior if a FormUpload is disabled in the FormPanel.onSubmit() handler (if disabling a FormUpload is kind of a stupid thing to do, uh, FHMP)? -- http://groups.google.com/group/Google-Web-Toolkit-Contributors
