RequestFactory strange issue with embedded proxy
Hi,
I have a very strange problem with RequestFactory. I have a hierarchy of
embedded proxies :
QuoteRequestProxy
|_ PropertyInfoProxy
|_ LocationProxy
Everything was working fine, until I tried to create a new proxy from the
client :
QuoteRequestContext ctx = requestFactory.quoteRequest();
QuoteRequestProxy quoteRequest = ctx.create(QuoteRequestProxy.class);
And here's the error message I get :

Re: RequestFactory strange issue with embedded proxy
OK, I got it, explaining the problem gave me the insight I needed.
My QuoteRequestProxy.setProperty() method got mixed with the method
generated by RequestFactory. I changed the method name, and it worked.

RequestFactory, Multi-threading and GAE pricing
Hi, I have read quite a lot about the new pricing of GAE, and it kind of got me confused. I understood that in order to save money, we should optimize instance time and the best way to do that is to use Java's multi-threaded capabilities. However, for the GWT application I am working on, I feel like I am currently working at higher level of abstraction and that I have no idea of what's happening under the hood. Using RequestFactory or GWT RPC, when I launch a request from the client, does it mean that my GAE instance will be unavailable until the request has been processed ?

Refactored 2.3 RequestFactory creates frozen proxies
I ran into a problem with the new com.google.web.bindery.requestfactory in dev mode, when going back to the deprecated package everything works fine. I got this code : CarRequestFactory requestFactory = GWT.create(CarRequestFactory.class); requestFactory.initialize(eventBus); CarRequestFactory.CarRequestContext ctx = requestFactory.carRequest(); CarProxy car = ctx.create(CarProxy.class); car.setName(name); Surprisingly, this last line of code triggers an exception : java.lang.IllegalStateException: The AutoBean has been frozen at com.google.web.bindery.autobean.shared.impl.AbstractAutoBean.checkFrozen(AbstractAutoBean.java:195) at com.google.web.bindery.autobean.shared.impl.AbstractAutoBean.setProperty(AbstractAutoBean.java:270) And I couldn't unfreeze the proxy with a call to RequestContext.edit() For the moment, I guess I'll stick with the old version of RF, keep us updated on when we should migrate. -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: MVP - model question
A Curse ! ^^
Do you mean you want to share a model between multiple presenters ?
That's the not the MVP described by Ray Ryan way of doing things. A
presenter shoul
d be able to get a model object in two ways only :
- RPC call
- being passed an event by the EventBus
Maybe your models are too big, or your presenters too small.
Anyway, if I wanted to do something like this (god preserve me), I'd
go with a Ginjected @Singleton model object. Or else, a model object
that listens to the Presenters via the EventBus to know when it needs
to update or send itself to the server.
On 22 sep, 16:44, mike b mbaker.t...@gmail.com wrote:
The Google's Contacts example is nice for showing events, history, and
the MVP pattern, but too simplistic to really show complex models.
I have a situation where I would like to use the same model object
between several presenters. Also note that this model object is
created on the client side and passed to the server later. It will
never be retrieved from the server.
What is the best way to accomplish this?
I was thinking that I could use the AppController event framework
(onChangeValue) to handle creation/passing the model to the different
presenters.
Something like this...
public void onValueChange(ValueChangeEventString event) {
MyExampleObject eo = new MyExampleObject();
if (token.equals(list)) {
presenter = new ContactsPresenter(rpcService, eventBus, new
ContactsView(),eo );
} else if (token.equals(add)) {
presenter = new EditContactPresenter(rpcService, eventBus, new
EditContactView(), eo);
}
Thoughts? Ideas? Curses?

Mike

Re: Custom map
I heard some guys did pretty crazy stuff with OpenLayers, like Tetris- style games. So I guess displaying an image in background and some clickable geometries and/or icons on top should be pretty easy. BTW, OpenLayers is a web mapping JS library.

Correction... If you want to know the type of the created object, It's
almost type safe. :P If you are alright by knowing it's a Widget,
it's type-safe. Here's a tidier version of the code:
Almost type-safe:

public static T T createInstance(ClassT theClass) {
if (theClass == TextBox.class)
return (T)new TextBox();
else if (theClass == Button.class)

}
}
Type-safe:
public class Reflector {
public static T extends Widget Widget createInstance(ClassT
theClass) {
if (theClass == TextBox.class)
return new TextBox();
else if (theClass == Button.class)
return new Button();
else
throw new RuntimeException();
}

return new MyClass1();
else if (class == MyClass2.class)
return new MyClass2();

It is type safe, although you can have a
CouldntInstanceClassException() if you forget to add the corresponding
comparison.

You can do that on the client side. Although you don't have

and compare classes using instance.getClass(). Every time you add a
new class you want to use reflections with, you can add a new else if
(instance.getClass() == MyClass.class){ return new MyClass(); }
That was what I did when I needed to use reflections on the client

Re: How to integrate GWT app into an Existing Project ? (Details Inside)
To get a grasp on GWT-RPC, start with a tutorial. This one looks good : http://developerlife.com/tutorials/?p=125 Think of RPC as a communication channel between your client and your server. Your client handles UI logic, the server handles business logic. Your client will need to display business data, but it has no connection with the database. So it has to call the server side to get the data it needs to display. The objects that will be passed between the client and the server will be in the shared package and they need to implement java.io.Serializable. You define the RPC services signatures, so it's up to you to decide what objects your client and server will use to communicate. It can be anything from a simple String to a complicated transfer object. On the server side, you're just like in any Servlet container, so your old java code should work just the way it used to. The only difference is that it will implement the RPC services the client needs. I guess the reason no one else bothers to answer is that it is all pretty basic GWT stuff, and they consider you should be able to find the answers yourself with the first tool any developer : Google Search.

Regards, Chirayu On Aug 6, 1:11 pm, Mikael Couzic mikaelcou...@gmail.com wrote: Hi, First, consider you developed the client side of the application, which means your code will be compiled in JavaScript and provide the UI. The GWT compiler needs to know which classes need to be compiled in JS. You'll find in your Module.gwt.xml file the following line : source path='client' / This line tells the compiler to translate in JS all the classes in the client package. Most probably the old project's code is not in this package. However, compiling all the project in JS is definitely not the way to go. You need to think about what part of the application should be in the client and which part should be in the server. The client calls the server via RPC. You'll find many tutorials on the subject with a Google search. So your project should look like this : - client (package) - server (package) - shared (package) - Module.gwt.xml (file) The shared package stores the classes that will be used to communicate between client and server (those classes must be serializable). Don't forget to add in your Module.gwt.xml : source path='shared' / In your case, it would be best to put all the old code you want to reuse in the server package. You'll then need to define and implement the RPC services your client side will call. Consider applying the RPC- Oriented Command Pattern and its implementation, GWT-Dispatch. Good luck !

In Eclipse you specified the dependency on another project, which is enough for Dev mode, but is not sufficient for compilation. If you use Ant or Maven, you need to specify the dependencies in your build scripts.

Re: How to integrate GWT app into an Existing Project ? (Details Inside)
Hi, First, consider you developed the client side of the application, which means your code will be compiled in JavaScript and provide the UI. The GWT compiler needs to know which classes need to be compiled in JS. You'll find in your Module.gwt.xml file the following line : source path='client' / This line tells the compiler to translate in JS all the classes in the client package. Most probably the old project's code is not in this package. However, compiling all the project in JS is definitely not the way to go. You need to think about what part of the application should be in the client and which part should be in the server. The client calls the server via RPC. You'll find many tutorials on the subject with a Google search. So your project should look like this : - client (package) - server (package) - shared (package) - Module.gwt.xml (file) The shared package stores the classes that will be used to communicate between client and server (those classes must be serializable). Don't forget to add in your Module.gwt.xml : source path='shared' / In your case, it would be best to put all the old code you want to reuse in the server package. You'll then need to define and implement the RPC services your client side will call. Consider applying the RPC- Oriented Command Pattern and its implementation, GWT-Dispatch. Good luck !

I was asked as my internship assignment to make with GWT, the client- side of this huge project they have for internal usage. This project's client-side had been in 'HTML+JSP' till now. Now, I have successfully made the client-side, but face a bad-bad problem in integrating my app with the project. I had no knowledge and included the old project's code through SVN in my GWT app project, imported the packages and made calls to methods their and was able to write the client-side code without any errors. But on final compilation, it says 'No Source Code found' for the imports I made from the old project. I learnt that my approach is wrong, and a possible solution is to maybe use the concept of GWT-RPC, but can somebody explain it to me step-wise and in clarity. I'll be happy to provide more details if asked. Please help me, I'm like in a sad situation, and success of my work at the start of my career is very imporant.

Re: Instantiate composite on the server side
Sounds like you violated the SRP principle... If I got it right, Composite depends on the DOM, which doesn't exist server-side, so I don't think it is possible. A solution would be to encapsulate the functionnality you want to use server-side in a POJO. Your composite would then delegate to the POJO, which could be reused server-side. And if you wish to push further towards great design, embrace MVP !

Re: Share user input data within MVP + Lady_Gaga
Well, I pretty much agree with Eric. I believe the event should'nt depend on the listeners, rather it should be defined in consideration of the presenter that fires it. The attributes stored in the event are the ones that make sense in its own context (that helps a lot I know ^^). In your registration example, I'd fire a RegistrationSubmittedEvent that holds all the details of the registration. No need to create a data object, your event is your data object. However, you can instantiate model objects in the presenter and hold these objects in the event instead of duplicating instantiation code all over the listeners. But in that case, be careful, your model objects are shared and shouldn't be edited (consider making them immutable). I hope that helps !

Than in future, we have to add that specific information in the event thrown by presenter 1 .. right ? I mean information passed in the event is limited by what is required by listening presenters?. For eg a registration view may have different textboxes for first name, address etc and the intial event may only be thrown with the information that submit button is clicked. And later on for future presenter 3q we may have to add first name in the event thrown by presenter 1. Do you create event in the first place with all the information available to accomodate all future presenters? Do you create a Value object to pass this heavy weight information from one presenter to another?

In fact, you shouldn't be thinking about presenters 2a, 2b, or 2c when writing presenter 1. Presenter 1 should just fire change events when its data changes. Presenters 2a, 2b, 2c, and future presenters 3q and 7f should simply add event handlers to presenter 1 and pick out the information they need.

Re: GeoMap alternative?
Well, I know exactly how to do that with GWT-OpenLayers, but except GeoMap I'm not familiar with the alternatives so I can't compare. Anyway if you want to implement these features in a GWT application, I highly recommend using a GWT-integrated API if you want to avoid the overhead and maintenance issues.

Re: GWT 2.0.4 is now available
I'm pretty sure the GWT group is not providing them because very few, if any, projects internally utilize maven. I do not agree.
