Re: [gwt-contrib] Java to WebAssembly Compiler
Would not a bytecode to WebAssembly compiler make more sense instead? There are many great JVM languages and Java is a major one but still there are many other great languages that have bytecode as a compilation target. Would it not make more sense to a have a bytecode to WebAssembly compiler once GC is support by WebAssembly? -- ._. -- You received this message because you are subscribed to the Google Groups "GWT Contributors" group.

Showing and Editor's errors
If an Editor doesn't satisfy an Entity's constraints, it calls
driverCtx.fire(new ReceiverVoid() {
@Override
public void onConstraintViolation(SetConstraintViolation?
violations) {
dialog.setText(Errors detected);
Driver.DRIVER.setConstraintViolations(violations);
ListEditorError editorErrors = Driver.DRIVER.getErrors();
for (EditorError editorError : editorErrors) {
Logger.getLogger(editorError.getMessage(): ).log(Level.INFO,
editorError.getMessage() + ); // prints two constraint violations
}
}
Are the constraint violations visualized in some way? Because I don't see
any visualizations
Before firing the Receiver I do
final RequestContext driverCtx = Driver.DRIVER.flush();
if (Driver.DRIVER.hasErrors()) {
dialog.setText(Invalid input);
return;
}
but *Driver.DRIVER.hasErrors()* remains always *false* although *
onConstraintViolation* is executed when some fields are missing.

SuperDevMode and server-side code
I want to run my RequestFactory using GWT' SuperDevMode. The client-side code compilesruns fine but as soon as I make any RF-using server call I get an exception because server-side code isn't supported in SuperDevMode yet. The reason is: Currently, Super Dev Mode doesn't support running Java web apps (war files) like classic Dev Mode. The workaround is to run them on a separate server.https://developers.google.com/web-toolkit/articles/superdevmode But how should I run two separate servers (GWT compilation server my app server) on the same port? And the same port is required because how else should I redirect my RF calls to another port of the same server? -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Delegate an Editor's edit() save() functionality via Activities Places' Presenter to an Activity class?
I have an architectural question. I've introduced
EntityWorkflowhttps://developers.google.com/web-toolkit/doc/latest/DevGuideUiEditors#Quickstart
to
my Activities
Placeshttps://developers.google.com/web-toolkit/doc/latest/DevGuideMvpActivitiesAndPlacesenabled
app. In GWT's
*Activities Places* there are the *Presenter* interfaces which is used by
a view to delegate the implementation of certain action (like edit()
save()) to the *Activities* class. So does it make sense to treat an *
EntityWorkflow* as a AP view and to apply AP's action delegation feature
here? Or to speak code-wise:
public class EntityEditorWorkflow {
// Empty interface declaration, similar to UiBinder
interface Driver extends RequestFactoryEditorDriverEmployeeProxy,
EmployeeEditor {
}
private static final Driver driver = GWT.create(Driver.class);
@UiHandler(save)
public void onSave(ClickEvent event) {
* // implementing the actual SaveEntity code*
Person edited = driver.flush();
if (driver.hasErrors()) {
// A sub-editor reported errors
}
doSomethingWithEditedPerson(edited);
* vs. *
* // ...*
* presenter.save(entity);*
}

Support for custom time zones in GWT
GWT's Date object operates just like its JavaScript counterpart in a user's
system time zone. Is there a way to override GWT's Date object time zone?
Creating something like
public class FakeDate extends Date {
public FakeDate(String timeZoneConstantJson) {
FakeDate.timeZoneConstantJson = timeZoneConstantJson;
TimeZoneInfo timeZoneInfo =
TimeZoneInfo.buildTimeZoneData(FakeDate.timeZoneConstantJson);
TimeZone timeZone = TimeZone.createTimeZone(timeZoneInfo);
int currentDateOffsetInMin = timeZone.getOffset(this);
FakeDate.currentDateOffsetInMs = currentDateOffsetInMin * 60 *
1000;
super.setTime(super.getTime() - FakeDate.currentDateOffsetInMs);
}
}
...doesn't work with RequestFactory proxy classes because they expect the
Date super class instead of the *FakeDate* subclass just like the model
classes that have a Date field (which has to stay for reasons that would
take a while to explain :).

RequestFactoryEditorDriver remains dirty
I followed the Editor
examplehttps://developers.google.com/web-toolkit/doc/latest/DevGuideUiEditors
using RequestFactoryEditorDriver
for RF-driven persistence. But it doesn't work for me.
When I call
*
*
*public class EmployeeEditor extends Composite implements
EditorEmployeeProxy *
the model data is transfered into the *Composite* and all UiBinder fields
get their values.
I use this code
void edit(EmployeeProxy employee) {
driver.initialize(cf.getRF(), employeeEditor);
final EmployeeReqCtx reqCtx = cf.getRF().employeeReqCtx();
driver.edit(employee, reqCtx);
cf.getLogger().log(Level.INFO, driver.isDirty: +
driver.isDirty());
}
to achieve this.The *driver*
interface Driver extends RequestFactoryEditorDriverEmployeeProxy,
EmployeeEditor
*is clean at this point*. As soon as I call
*void save() {*
*cf.getLogger().log(Level.INFO, driver.isDirty: +
driver.isDirty());*
*final RequestContext reqCtx = driver.flush();*
*if (driver.hasErrors()) {*
*cf.getLogger().log(Level.INFO, DRIVER HAS ERRORS.);*
*}*
*cf.getLogger().log(Level.INFO, driver.isDirty: +
driver.isDirty());*
*
*
*
*
*// Send the request*
*reqCtx.fire(new ReceiverVoid() {*
*@Override*
*public void onConstraintViolation(SetConstraintViolation?
errors) {*
*cf.getLogger().log(Level.SEVERE, ERRORS DETECTED ON THE
SERVER + errors.size());*
*}*
*
*
*@Override*
*public void onSuccess(Void response) {*
*cf.getLogger().log(Level.SEVERE, SUCCESS!);*
*cf.getLogger().log(Level.INFO, driver.isDirty: +
driver.isDirty());*
*}*
*});*
*cf.getLogger().log(Level.INFO, driver.isDirty: +
driver.isDirty());*
*}*
the *driver becomes dirty *and the *SUCCESS! *message appears. So the
entity has been persisted at this point? However the subsequent log message
in *onSuccess() reports* that *the driver is still dirty*. And when I call *
save()* again, the
*Caused by: java.lang.IllegalStateException: A request is already in
progress*
*
*
exception is thrown*.*
My persistence framework is Objectify and the corresponding RequestFactory
using JUnit tests are working and modify the entities as expected.

It's works very well... provided you previously queued a call to your
put() method in the RequestContext !
The example does this just before calling edit() on the EditorDriver.

You should rewrite your test to:
- call delayTestFinish()
- pass some callback to your check() method to be notified when the
response comes back
- call finishTest() from that callback
I suspect the error comes from the fact the test is actually finished when
the response comes back, and that code running outside the tests is causing
the whole thing to fail.

RequestFactory: How to retrieve an EntityProxy within another EntityProxy?
I've got sth. like:
@ProxyFor(value = Report.class, locator = CommonLocator.class)
public interface ReportProxy extends EntityProxy {
// ...
Integer getUserId(); *// works*
void setUserId(Integer userId);
UserProxy getUser(); *// doesn't work*
void setUser(UserProxy user);
}
@Service(value = ReportDAOService.class, locator = DAOServiceLocator.class)
public interface ReportRequest extends RequestContext {
// ...
RequestListReportProxy getReports(Integer sessionId);
}
Calling getReports(sessionId) retrieves the reports where *getUserId()
returns the proper userId* whereby *getUser()* returns *null. *On the *
server* side *calling getUser() on result.get(0) * returns the proper
entity/object value as well.
*
*
Any idea, *how I can get getUser()'s UserProxy representation?*

Best practice for working with separate GWT modules and their inheritance
Assumed I've a Customer.gwt.xml and a Manager.gwt.xml module. Manager inherits Customer because I want to use Customer's functionality and RF's proxy classes in Manager. Ok, those proxy classes could be also put into a Common.gwt.xml but let's omit this option for the moment. Now the problem is when I call the Manager view/module, I also see the Customer widget in the same view. However I just want to see the Manager widget when I call the Manager view and not the Customer widget which I want to call separately.

A static EventBus / SimpleEventBus: Pro Contra
EventBus is a really nice mechanism to *decouple methods from callbacks* by adding corresponding event handlers to an EventBus. By nature EventBus is something that should be known to both classes, the calling and the called class.

Create custom callbacks to achieve synchronous code execution
It seems that Dev Mode code runs synchronously... Otherwise I can't explain a bug that occurs only in production mode where the results are already there before a table has been cleaned to receive those new results and still has its outdated results. So both are mixed, although I call cleanView() before getResults(). But this doesn't matter because JS runs asynchronously. So *getResults()* is executed before *cleanView(). *What I need is synchronous code execution, *I need a callback*. How can achieve that *getResults()* will be only executed once *clearView()*has done its job?

Generating module.cache.js instead of module.nocache.js
The default behavior of GWT is to generate the *module.nocache.js* versions. But how can I generate a *module.cache.js* version of a module?

Really useful insights! If you enable caching for the *.nocache.js file, then you explicitly allow intermediate servers/proxies, and browsers, to serve/use a possibly obsolete version of you app, without necessarily checking for a fresher on at your server. That means your servlets have to be prepared receiving requests from such versions even after you pushed an update to your server. That's also what I had in mind. I just wondered why so many Google apps use the *.cache.js version.

I mean GWT's GWTTestCase extending JUnit that's not redering any UI. Therefore the dev mode re-compilation time could be shortened (must not but could). Unit-testing is about software quality. The most important gains are in the long run, because a set of automated tests that can be replayed at any time will ensure you don't have regressions. For me JUnit is also about TDD. Avoiding regressions is another thing... With GWT, you should try as hard as possible to use plain JUnit (or TestNG or whatever) tests vs. GWTTestCase, because the former are much faster; and that's one of the main goals of using MVP (by mocking your view, you no longer need a GWTTestCase to test your presenter logic). I've hoped for this kind of tips. This is also where you'll have the most important productivity gains: writing unit tests for your presenters allows you to develop in short iterations, without the need to even start up the DevMode.

Re: 2.4: Is gwt-servlet still necessary when using RF instead of RPC?
Thx a lot for uploading the JARs to Maven Central!
Unfortunately I've got your message just now. In the meantime I came to the
same result which background you've described. The absolute minium to get RF
+ GWT working is:
dependency
groupIdcom.google.gwt/groupId
artifactIdgwt-user/artifactId
version${gwt.ver}/version
scopeprovided/scope
/dependency
dependency
groupIdcom.google.web.bindery/groupId
artifactIdrequestfactory-apt/artifactId
version${gwt.ver}/version
scopeprovided/scope
/dependency
dependency
groupIdcom.google.web.bindery/groupId
artifactIdrequestfactory-server/artifactId
version${gwt.ver}/version
/dependency
Also the scopes are set as small as possible. requestfactory-server has to
be in the *compile* scope as it contains the validation-api (which was a
separate JAR in previous versions).

Hi Alexander,
If using RF only, you no longer need gwt-servlet, just
requestfactory-server, which is now available in Maven Central. The POM for
requestfactory-server also declares the javax.validation and json
dependencies so you no longer need them explicitly in your project POM;
however, you do need requestfactory-apt as shown in the wiki page below. You
can pull in requestfactory-server as follows:
dependency

artifactIdrequestfactory-server/artifactId

RequestFactory: Advantages of using the ServiceLocator pattern
I think using ServiceLocator boils down to Methods that return a Request object in the client interface are implemented as static methods in the service class. Alternatively, they may be implemented as instance methods in a service object returned by a ServiceLocator. what pretty much describes how SL works. An obvious advantage of using SL is that you don't clutter your data model classes with any related methods.

Re: RequestFactory: Advantages of using the ServiceLocator pattern
But what's about this case: This method is from a server-side entity class
that has to associate it's *user* field with a given user (retrieved by its
userId).
public void setUser(final Integer userId) {
this.user = User.find(userId); // this is what I need to do using
the static way
// below is what I have to do when I'm using SL
// MainServiceLocator mainServiceLocator = new
MainServiceLocator();
// UserDAOService userService = (UserDAOService)
mainServiceLocator.getInstance(UserDAOService.class);
// userService.find(User.class, userId)
}
Ok, the SL could be simpler but the point is: I've to instantiate the SL in
order to use the find method which could be declared static.

Best practice for using values returned in callbacks (RequestFactory)
In GWT and particularly the RequestFactory framework many callbacks are used
to retrieve certain values
void callBack(final Integer userId) {
final MainRequestFactory.ResourceRequest reqFactory =
mainRequestFactory.resourceRequest();
final com.google.web.bindery.requestfactory.shared.RequestInteger
req = reqFactory.getUserResourceId(userId);
req.fire(new ReceiverInteger() {
@Override
public void onSuccess(final Integer response) {
System.out.println(My VALUE I want to return or assign to
globally accessible variable = + response); // *MyValue*
}
});
}
However I cannot neither return MyValue or assign it to a (even static)
field because the callBack is asynchronous.
What is the best (a good one is fine enough too :) practice to process *
MyValue*?

Just omit this and it should work. Yep, that's basically what I've done too but I could not imagine assigning a value to a (global) field could be advisable. If you want to be complete you could write it the long way RealClass.this.variablename. I do this all the time in my async callbacks. But its only useful if you want to remember some information obtained by an async call. That's almost always the case. If you really need to process the response you have to do it in the onSuccess method either directly or by calling a separate method (or by firing an event which is basically the same as calling a separate method). So If I have a callback that requires a value from another callback, I have to chain these callbacks?

On Friday, August 5, 2011 1:06:14 PM UTC+2, Jens wrote: Yes you have to use chaining or you introduce a new service method that does all the work in just one server request. If you have code flows like finding an ID_b for a given ID_a and then immediately use ID_b to fetch the final object you could create a specialized method that takes ID_a and directly fetches and returns the final object. Finding ID_b would then only happen on server side. I prefer the last option as I want to reduce server requests as much as possible. Plausible. If you have to chain then you should call good named methods in your callbacks onSuccess methods to start the next server request. I think this will increase readability at least a bit. Might increase it but I'm afraid chaining produces badly readable code by its nature. Working with methods which are independent from each other would simplify many things. OTOH you can do everything server-side which encourages to write very performant code. Thx for the enlightenment!

GWT is for apps — right? But what's about static pages? (GWT's Future Plans...)
GWT is a framework for building Ajax apps that act as clients and (optionally) communicate with a kinda RESTful backend via RPC or using RequestFactory (both are JSON based). That's my to the point understanding of GWT. But what's about static pages? To deliver static content, especially for search engines and other crawlers GWT might be not the best choice (yet?) because the whole GWT app is located in a single JS file and other subsequently fetched files. Those crawlers need static snapshots of a certain page state. In fact there are approaches and proposals to make Ajax apps crawlable. This is a a general proposal from Google of how to make an Ajax page crawlable http://code.google.com/web/ajaxcrawling/. And Acris is a GWT-based framework that implements Google's proposalhttp://code.google.com/p/acris/wiki/AcrisSEO (haven't tried it, don't know how good it is). However both approaches are everything else but straightforward or even fasteasy to apply to already existing Ajax/GWT apps. So my question is primarily directed to *GWT core devs*: *Are there plans to implement an easy-to-use static snapshot of a certain Ajax state feature into GWT? *Or is this a problem domain that will never be addressed by GWT? * * The problem arises from the fact that a company cannot rely on GWT only if it wants to maintain a SEO-friendly and crawlable content-driven page. For this purpose Wicket, Tapestry and other Java frameworks have to be used. -Alex -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.
