Re: RPC Issues - Lifespan of Data from a RPC
I was wondering if anyone knows of a way to run a function after the
RPC is complete.
The completion of a RPC call is signaled by the call to the onSuccess
method of the asyncCallback you pass to the RPC as the last argument.
So how does this answer your question ? Let's take a concrete example.
Let's say you call your rpc in the following way:
code
myRPCAsyncInstance.myMethodCall(parameter1, parameter2, ...,
parameterN, myCallback);
/code
This is how you would implement your callback to call a method call
doSomethingWhenRpcIsFinished:
code
AsyncCallbackMyReturnObject myCallback = new
AsyncCallbackMyReturnObject(){
//This is the method called when the RPC call failed
public void onFailure(Throwable t){
GWT.log(RPC failed);
}
//This is the method called when the RPC finished successfully
public void onSuccess(MyReturnObject result){
doSomethingWhenRpcIsFinished();
}
};
/code
Hope that helps,
Salvador

Thank you for your input, what was happening is once the RPC was
complete the data that I was adding to the ArrayList would disappear.
So I decided to do something ugly, but it works. I am writing the data
onto a invisible div on the page then getting it then adding it to the
ArrayList. It seems to work just fine.
I am new to GWT but I am starting to get a basic understanding on how
these things work.

Well, the indexOutOfBoundsException can't possibly be thrown by the
method add of an ArrayList (that's the type of productArrayList, isn't
it?). In fact there's nothing in your snippets that'll throw that
exception. Did you debug the method call on the server side ?
Somewhere in your Eclipse or HostedMode console you'll have a complete
stack trace that'll tell you the exact line of code that's throwing
that exception. I suggest you read it carefully.
As for the lifecycle of your RPCs, it is the normal lifecycle of a
servlet.
Hope that helps,

I tried to find this topic already on the discussions but could not
find it.
Currently using GWT 1.5.3
I am making a RPC to call to read XML and call a function that loads
the data into an ArrayList of classes. I have made a class that
implements RequestCallback(LoadData) and takes in my mainClass
example:
LoadData loadData = new LoadData(this);
String url = xmlString;
RequestBuilder requestBuilder = new RequestBuilder
(RequestBuilder.GET, url);
try {
requestBuilder.sendRequest(null, loadData);
} catch (RequestException ex) {
//Window.alert(exception);
}
Inside the RPC class:
mainClass.addProducts(id, sku, name, catagory) ;
inside my main class:
public addProducts(int id, int sku, String name, String catagory) {
productArrayList.add(new product(id, sku, name, catagory);
}
But when I call a method on my productArray it just says index out of
bound (basically the arrayList is empty) but I know it is calling the
addProduct method
I am guessing the lifespan of the data is tied to the lifespan of the
RPC call.
What sort of things can I do to get around this(assuming my
assumptions are correct)?
I greatly appreciate the help and apologize if this topic is covered
somewhere already.

Re: Failed to import and run gwtrpc-spring example with Google plugin
Hi,

{/,C:\Personal\Project\GwtRpcSpringExample\war}
java.lang.UnsupportedClassVersionError: Bad version number in .class file
This exception can occur when the source is built targeting a JDK that
is not supported by the JDK attempting to run it. In the above
example, if the servlet was built targeting only JDK 1.5, but the web
server runs JDK 1.4, the above exception will occur.
So check that you're using the same jdk to compile and to launch
hosted mode and also try cleaning your project before launching the
hosted mode (Project Clean ...).

Re: @gwt.TypeArgs gwt 1.6 specification documentation
Dear BlessedGeek, The requirements should be quite clear to any java developer (unless said developer is completely unaware of all of the post 1.4 jdk enhancements). When the documentation says: In GWT 1.5, @gwt.typeArgs annotations have been deprecated in favor of parameterized types you should understand that instead of declaring a method this way: code /** * This field is a Set that must always contain Strings. * * @gwt.typeArgs java.lang.String */ public Set setOfStrings; /code You should declare it like this: code /** * This field is a parameterised Set. * */ public SetString setOfStrings; /code unbelievably and unacceptably give examples on how to use @gwt.TypeArgs using the pre-1.5 patterns. Well, it is neither unbelievably nor unacceptable, as sometimes you just can't declare parameterised variable and in those cases it's still helpful to know how to use @gwt.typeargs Cheers, Salvador On May 17, 12:58 am, Blessed Geek blessedg...@gmail.com wrote: Dear GWT team, This may seem trivial but I think even if it is worth just a paragraph or two, you should document the new requirements rather than just referring to unlike pre-gwt1.5, you have to used parameterised types in blogs and discussions.

Re: Cleaning GWT project with Google plugin
The myproject\war\WEB-INF\classes directory is in fact deleted by Eclipse. When you clean a project with Eclipse, it has to be recompiled, so Eclipse immediately recreates that directory and puts freshly compiled classes in it. As for the myproject\war\myproject, Eclipse doesn't know it has to be cleaned so it doesn't touch it. Normally you can delete it manually, as it is created by the GWT Hosted Mode each time you launch it.

Re: Failed to import and run gwtrpc-spring example with Google plugin
Hi
The problem still exist after I manually deleted both
myproject/war/myproject and
myproject/war/WEB-INF/classes directories.
I have JDK 1.5 and JRE 1.5 and 1.6 installed on my Windows:
C:\Program Files\Java\jdk1.5.0_18 (JAVA_HOME)
C:\Program Files\Java\jre1.5.0_18
C:\Program Files\Java\jre6
I'm using JDK 1.5 for development, and jre1.5.0_18 is the only Installed JRE
configured in Eclipse.
The JRE 1.6 is merely used for Google Chrome.
Can I safely tell that all Eclipse, GWT and Jetty are running on Java 1.5?

How to replace MouserListener in GWT 1.6
I imported an GWT 1.5 app for transforming it to a GWT 1.6 app. Every
listener is now marked as deprecated, so i'm currently replacing all
these. Anyway i do not know how to replace my MouseListener
implementations. Concretly speaking i use the folling implementations
public void onMouseEnter(Widget sender) {
//..do s.th. here
}
public void onMouseLeave(Widget sender) {
//..do s.th. here
}
that are demanded by the MouseListener interface. But i have not
figured out yet how to replace these with the new handler interfaces.
Does somebody know how to accomplish this?

Simple Example using event handlers, Google App Engine, Integrated Google Analytics
This is a simple GWT application using addClickHandler,
addChangeHandler and Integrated Google Analytics.
Demo - http://gwtexample.appspot.com/ - This application demo is
deployed on the Google App Engine.
SVN Source -
http://code.google.com/p/gwt-examples/source/browse/#svn/trunk/gwt_handler_example/src/com/gawkat/gwt/example_handler/client%3Fstate%3Dclosed
Notes: (check out the svn source for more code)
I really like the new event system. This simple example only uses a
small potential of the event system. Its much easier to observe
events. It was harder to understand at first, but its much easier to
understand once learned. Its well worth the change from listeners!
Something to note if you want to fire a change event.
private void fireChange() {
NativeEvent nativeEvent = Document.get().createChangeEvent();
ChangeEvent.fireNativeEvent(nativeEvent, this);
}
Instead of adding listeners you register handlers.
/**
* when firing a change event, this handler is used
*/
public HandlerRegistration addChangeHandler(ChangeHandler handler) {
return addDomHandler(handler, ChangeEvent.getType());
}
/**
* allows for observing click events on the entire widget
*/
public HandlerRegistration addClickHandler(ClickHandler handler) {
return addDomHandler(handler, ClickEvent.getType());
}

onMouseEnter (I don't know which so you'll have to try them out):
http://google-web-toolkit.googlecode.com/svn/javadoc/1.6/com/google/gwt/event/dom/client/MouseOverHandler.html
or
http://google-web-toolkit.googlecode.com/svn/javadoc/1.6/com/google/gwt/event/dom/client/MouseUpEvent.html
Hope that helps,

I imported an GWT 1.5 app for transforming it to a GWT 1.6 app. Every
listener is now marked as deprecated, so i'm currently replacing all
these. Anyway i do not know how to replace my MouseListener
implementations. Concretly speaking i use the folling implementations
public void onMouseEnter(Widget sender) {
//..do s.th. here
}
public void onMouseLeave(Widget sender) {
//..do s.th. here
}
that are demanded by the MouseListener interface. But i have not
figured out yet how to replace these with the new handler interfaces.
Does somebody know how to accomplish this?

Social Collaboration Through Application State Reference
My beginning thoughts about Collaboration through links: http://codintips.blogspot.com/2009/05/social-collaboration-through.html The question is, whats the best way to reference the entire applications current state through a link? Of course, putting all the parameters into the link is the answer, but is that really the best way? An application has so many widgets and widgets that have widgets with different parameters that make the view of entire application, which wouldn't be pragmatic to set every parameter into a the link. I'd like to think there is a better way to link into the applications current state. Why do I ask this. Because, I like to send a link of the current applications state/view, to someone else so we can start from that point and collaborate on what we are seeing. I thought I would mention this to create conversation on this topic. I haven't actually thought to deeply into how I would implement this over an entire application. I will have to get adjusted into the new event system before I approach this. Something to chew on.

Re: Cleaning GWT project with Google plugin
Hi Salvador On Sun, May 17, 2009 at 9:14 PM, Salvador Diaz diaz.salva...@gmail.comwrote: The myproject\war\WEB-INF\classes directory is in fact deleted by Eclipse. When you clean a project with Eclipse, it has to be recompiled, so Eclipse immediately recreates that directory and puts freshly compiled classes in it. You're right, the myproject\war\WEB-INF\classes is indeed re-created by Eclipse. This is observed in Windows Explorer, but the new classes folder is never be shown in Eclipse anymore. As for the myproject\war\myproject, Eclipse doesn't know it has to be cleaned so it doesn't touch it. Normally you can delete it manually, as it is created by the GWT Hosted Mode each time you launch it. It would be very nice if Google plugin can clean these directories too :D Thanks for your advice! -- Hez --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

[gwt-contrib] Re: gwt TRUNK seems to be to restrictive for what GWT.create can return
I am checking out the new gwt query code now. I was using a custom patched version of gwtquery 0.3 http://code.google.com/p/gwtquery/issues/detail?id=5can=4 So I will just have to re-do this patch before I can continue. Kind Regards Cameron 2009/5/17 Ray Cromwell cromwell...@gmail.com Cameron, Did you check out a recent version of GQuery? I've been checking in a lot of changes recently because I've revamped it for Google I/O re-release. It now implements about 98% of all jQuery functions. I've haven't looked at the older rebind rules, but there should be a fall-thru for non-matched browers to SelectorEngineImplJS. But John could be right, it could be that the fall-thru isn't working and IE8 is resolving to no binding. -Ray On Sat, May 16, 2009 at 7:41 PM, Cameron Braid came...@braid.com.au wrote: I am tryng gwt trunk r5406 and have run into issues with GWT's rebinding. here are some errors from my different modules : [java][ERROR] Errors in 'jar:file:/media/home/cameronbraid/.m2/repository/gwtquery/gwtquery/0.3-a/gwtquery-0.3-a.jar!/gwtquery/client/SelectorEngine.java' [java] [ERROR] Line 20: Rebind result 'gwtquery.client.impl.SelectorEngineImpl' cannot be abstract [java][ERROR] Errors in 'jar:file:/media/home/cameronbraid/.m2/repository/com/google/gwt/incubator/gwt-incubator/r1539/gwt-incubator-r1539.jar!/com/google/gwt/gen2/logging/impl/client/ClientConsoleLogHandlerImpl.java' [java] [ERROR] Line 206: Rebind result 'com.google.gwt.gen2.logging.impl.client.ClientConsoleLogHandlerImpl.Impl' must be a class [java][ERROR] Errors in 'jar:file:/media/home/cameronbraid/.m2/repository/com/extjs/gxt/1.2.2-r1236/gxt-1.2.2-r1236.jar!/com/extjs/gxt/ui/client/widget/form/NumberPropertyEditor.java' [java] [ERROR] Line 29: Rebind result 'com.google.gwt.i18n.client.constants.NumberConstants' must be a class These errors didn't occur using an older GWT trunk version r4619 Cheers Cameron --~--~-~--~~~---~--~~ http://groups.google.com/group/Google-Web-Toolkit-Contributors -~--~~~~--~~--~--~---

The NumberConstants change was due to adding runtime locales support, and you should no longer be GWT.create'ing it, but instead use LocaleInfo.getCurrentLocale().getNumberConstants(). If you really must do GWT.create, you can use NumberConstantsImpl but that is an implementation class and may change, and you will lose the ability to use runtime locales. -- John A.
