Thanks to all your help: german census results online
Hi there, https://ergebnisse.zensus2011.de/?locale=en shows not only germany's census results but it is also a gwt in life example. For me it was my first big public web project. The best of all choices i did was to take gwt. It was a steep learning curve but you all helped much especially with all new patterns for us like: mvp, activities places, di (with guice/gin) -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: In page (html) anchors don't work - they interfere with history tokens
can you explain how to use the html5 feature you mentioned? On Friday, 21 September 2012 16:55:51 UTC+2, Jens wrote: Have you tried to attach an event listener (DOM.addEventListener()) to these anchors and call ClickEvent.preventDefault() when you click on them? That could suppress the history change and you can scroll your html document yourself by reading the href attribute and searching the anchor you need to scroll to. But don't forget to remove the event listener if you don't need the html anymore. If ClickEvent.preventDefault() does not work you need to modify your anchors to a data-scrollTo=chapter1 class=linkStyleChapter 1/a or use div instead of a because you can't use href anyways. So remove the href attribute and put the information in a custom attribute. Your click handler would use the custom attribute to get the information where to scroll to. Obviously you have to do the scrolling yourself (Element.scrollIntoView()). In modern browsers you could maybe use HTML5 pushState instead of hash tokens for history management. In that case you probably don't have to change anything in your html document. But if you want IE compatibility this is not an option. -- J. -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

In page (html) anchors don't work - they interfere with history tokens
This question could also be answered herehttp://stackoverflow.com/questions/12509969/gwt-and-in-page-hyperlinks-chapter3-interfere-with-history-tokens :-). I want to add a html-document to a view. the html page contains an toc with anchors a href=#Chapter1Chapter 1/a and a name=Chapter1Chapter 1/a (very oldschool html). The problem is that on click on an item in toc gwt interprets this as goTo(Place with token chapter1) - the link is interpreted as adress to webapp/#chapter1 and this obviously fails. So how to add such html to a gwt widget and make the anchors work as expected (probably all anchors must be modified in some way?)? in meantime i tried wrapping the html in a frame - with no avail. -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

On server side i have a lib (can be modified) that produces png images and corresponding imagemap for mouse hover titles. But how to use them with gwt?

If your lib creates raw HTML for the image map then you probably only need the imageUrl and the raw HTML in your DTO and render the raw HTML directly using GWT's HTML widget. But you have to do some sanity checks on the raw HTML to prevent cross site scripting attacks. So if you can, build the HTML on the client side and only transfer the needed data from server to client. -- J. -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Development Mode in Eclipse stopped working - no errors, nothing on console
On integrating a library on server side of my gwt app (maven, gwt 2.4) the development/hosted mode stopped working. The app works fine if deployed and all unit tests and integration tests pass as before. If i start development mode (run/debug as web application) the develpoment mode view pops up but nothing else happens. normally the console should show some output but console keeps empty. So i don't even have a hint whats going wrong. Can you give some advice where to look / what to do to get at least a hint what's wrong? (if i check out the revision before the development mode works! - so some code changes should be the cause?!) Background about library i added (don't know if my problem relates to this):I had some problem on integrating the library. the library uses eclipse birt charting engine. This engine has a dependency to apachy derby db, this conflicted with another library. i solved this by excluding the derby dependency via maven. the second problem was a command line too long error on unit test - this was solved by updating the maven-surefire-plugin. -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: Development Mode in Eclipse stopped working - no errors, nothing on console
i did some researches: the hosted mode stops working if i only add the dependency - without using it. as mentioned above i checked out the revision before adding and using this lib. based on that revision i only added the dependency to pom and the hosted mode stops working. on deleting the dependency it is working again. -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

NullPointerException in generated PlaceHistoryMapperImpl (with factory)- how/when to setFactory (Problem only in hosted mode)
I am using PlaceHistoryMapperWithFactory as suggested
herehttp://stackoverflow.com/questions/10089964/places-that-share-all-but-prefix-or-how-to-use-placehistorymapperwithfactory.
The factory is set within my ClientModule (gin):
@Provides
@Singleton
@Inject
public final PlaceHistoryMapperWithFactoryTokenizerFactory
getPlaceHistoryMapper(AppPlaceHistoryMapper hm,
TokenizerFactory tf) {
hm.setFactory(tf);
return hm;
}
I watched the code with debugger (Breakpoints on two lines above and on
NullPointerException):
1. The factory is set within AbstractPlaceHistoryMapperF and hm with
set factory is returned
2. AppPlaceHistoryMapperImpl throws NPEx at return new
PrefixAndToken(ContentMenu, factory.contentMenuPlace().getToken(place));
because factory is null
What is going wrong here?
One probably important thing: This problem is only (re)producible in hosted
mode. If app is deployed it works fine!

thx thomas for fast reply,
the problem is indeed that two instances are created one
PlaceHistoryMapperWithFactoryTokenizerFactory instance and one
instances where constructors inject AppPlaceHistoryMapper (this one has
null factory).
But how to fix this? Your suggested provides-Code shouldn't change
anything, should it?
It depends.
If you have code that depends on AppPlaceHistoryMapper, then change the
return type of the provider-method to that.
And if some code depends on
PlaceHistoryMapperWithFactoryTokenizerFactory, and/or PlaceHistoryMapper,
then bind those types to AppPlaceHistoryMapper (see below).
So I tried your 2nd suggestion:
plus this in module:
bind(new
TypeLiteralPlaceHistoryMapperWithFactoryTokenizerFactory() {
}).to(AppPlaceHistoryMapper.class).in(Singleton.class);
*It is working! *
But with this every user of AppPlaceHistoryMapper get a different
instance - (i guess this is not really a problem) - is it possible to
get/bind a singleton.
Is it possible to bind AppPlaceHistoryMapper
and PlaceHistoryMapperWithFactoryTokenizerFactory to the same instance
of generated AppPlaceHistoryMapper Impl?
Yes:
bind(new TypeLiteralPlaceHistoryMapperWithFactoryTokenizerFactory() {
}).to(AppPlaceHistoryMapper.class);
bind(AppPlaceHistoryMapper.class).in(Singleton.class); // either that, or
a @Provides @Singleton method.
i.e.: when you need a PlaceHistoryMapperWithFactoryTokenizerFactory,
then use an AppPlaceHistoryMapper; and when you need an
AppPlaceHistoryMapper, then bind it as a singleton.

Re: best/good practices to keep Model in sync with Activity/Place and a view.
for example a showUserPlace and a EditUserPlace. Or in general there are often more than one usecase per model. And if i want a distinct url per use case i need different places. This cases could probably solved by let one userActivity manage two presenters (edit and show user). But then i have the same issue- how to inject the synchronized model from activity in presenter. But at the moment the problem is not that two activities. Now i have a very complicated logic on the model so i decided to put this logic out of activity/presenter (ui handling logic). here is the same problem how to let the activity interact with a model. (i linked the concrete problem above - for short: if used events i have the problem to register for an event and trigger an event(asking the model) all in start method seem to fail) On Tuesday, 24 April 2012 20:26:41 UTC+2, Jens wrote: Do you have a concrete example? So far I never stumbled upon a case where I was thinking hmm thats the same as in the other activity.

Re: Activity how to react on event that is triggered in start-method
i think this is not the problem. first i register for event then i fetch
the data that triggers the event. here is the code of start method:
@Override
public final void start(final AcceptsOneWidget panel, final
com.google.gwt.event.shared.EventBus eventBus) {
this.eb = new ResettableEventBus(eventBus);
view.setPresenter(this);
this.eb.addHandler(DynamicTableHashResolvedEvent.TYPE,
this);//handler registration
stateResolver.resolveState(((DynamicTablePlace)
pc.getWhere()).getTablehash(), eb);//triggers event
panel.setWidget(view);
}
the event triggered in start method will be received when next event is
triggered - so after the start method i am one event too late.

Re: Activity how to react on event that is triggered in start-method
you are right jens my first solution was a local eventbus - as you see my
stateresolver takes an EventBus as argument - but this didn't work either.
The current solution was copied from a gwt-example.
i used the solution with callback in two of my other activities. but my
feeling isn't very good with it - i never use the eventbus given in start -
why is there an eventbus?. because of this uncertainty i opened the other
threadhttps://groups.google.com/forum/?fromgroups#!topic/google-web-toolkit/ktF5b1jLxtY.
I thought resolving a string /token to a model(that needs more than just
call one service - probably i should refactor the services :-|) is a more
usual use case.
So i guess i will refactor it and use a delegate to handle the callback.
On Wednesday, 25 April 2012 10:49:52 UTC+2, Jens wrote:
Instead of using the EventBus you could also use a Callback in your
StateResolver. Seems to me that only the class that calls
stateResolver.resolve() is interested in the result, so there isn't a real
need for using an application wide event bus.
stateResolver.resolveState(, new Callback() {
void onSuccess() {
//call method that handles the state
}
});
Or you implement the Callback interface directly in your Activity (but
then I would rename it to StateResolverPeer.stateResolved(T state) or
something like that) and then simply call stateResolver.resolveState(,
this).
If there is a 1:1 relation I would not use event bus in most cases.

Re: best/good practices to keep Model in sync with Activity/Place and a view.
Thx The Problem about Scheduled command is that i loose test ability - one main reason i use MVP (want to test the P without GWTTestCase). But the Question is how to design such DAO's - i guess that's where i am failing at the moment. My current DAO is firing events - not usable in activities start method without ScheduledCommand.

Re: best/good practices to keep Model in sync with Activity/Place and a view.
Thanks - great idea, so i inject the abstract class com.google.gwt.core.client.Scheduler.

Re: how to make a clickable image cell?
Should be possible with ActionCell or ButtonCell. The image could be easily
added via render method. look at examples on gwt showcase like
thishttp://gwt.google.com/samples/Showcase/Showcase.html#!CwCellList
.
An image could be added to every kind of cell i think (from example):
String imageHtml = AbstractImagePrototype.create(image).getHTML();
...
@Override
public void render(Context context, ContactInfo value, SafeHtmlBuilder sb) {
// Value can be null, so do a null check..
if (value == null) {
return;
}
// Add the contact image.
sb.appendHtmlConstant(trtd rowspan='3');
sb.appendHtmlConstant(imageHtml);
sb.appendHtmlConstant(/td);
...

Re: Shortest way to get a List of widgets with text and a button (VerticalPanel, CellList..?)

with flow panel it was very easy to implement. the problem was to get the

stuff, with its selection model i can easily do what i want. ('til now i

Or use display:block in CSS (or a block element –such as a div– as the

I'm sorry but GWT doesn't save you from learning HTML, JS, DOM and CSS. If
you don't want to learn those, then maybe you shouldn't have chosen GWT to
begin with: Flex or similar might have been a better choice (for you as a
developer; I absolutely hate Flash and Flex as a user, so from my point of
view this is absolutely not a better choice, but this is just my opinion)
now i began with cell-stuff. at the moment i try to extend ActionCell and
overwrite it's render (just calls sb.append some text before calling
super.render). I also tried (for 10min) composite cell but i didn't
realized what i should do about hasCells. (i guess there is no in deep
documentation of cell-stuff)
A CompositeCell is similar to a CellTable except it renders things side by
side, not in columns (and there are no headers/footers). Instead of
defining Columns for a CellTable, you define HasCells for a CompositeCell,
and instead of rendering each cell in a table column (as CellTable),
CompositeCell renders them side by side as a single cell.

Shortest way to get a List of widgets with text and a button (VerticalPanel, CellList..?)
i need a list of label plus button entries (the button says delete line). The List won't become very long (100 entries). So the first question is: Is CellList a good approach?

Resolving state provided by place in a central class
in my application most activities rely on infos provided by current place. all infos of such place define the state of activity. the problem is that all infos are provided as strings and must be resolved to objects (i.e. userID=0815 must be resolved to a user object). In my case many activities share such a state (ShowUserActivity, SelectUserActivity both need current(Selected)User). At the moment the code to resolve a state is redundant across those activities -- very bad. So i want to centralize each kind of state. In many cases async. services are needed to resolve the infos. So how is a good way to centralize this asynchronous process? One Idea i have in mind is to let this class hear PlaceChangeEvents to update itself. Because of the asynchronous nature of the update i probably need a UpdateStateEvent and each activity must register to it. But is there a way to defer the loading of an activity 'til state is resolved (there is no need to start the activity). Or in general is there a way to make asynchronous calls synchronous by deferring until onSuccess/onFailure? Or this all is probably bullshit and you have a better idea to solve this kind of problem? -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Implementing Places that share all but have different prefix
Sometimes i have two places that differ only in thier prefix. For example a SelectionPlace and a ResultOfSelectionPlace. So both places share all code but differ in @Prefix(value...). At the moment i implemented this by using an abstract class but i have to copy the code of the tokenizer to get tokenizers with different prefixes. Is there a way to let the concrete class only set the prefix of a shared tokenizer class?

Re: hard time to get GWTTestCase to work
thx, the problem is how to fix it. i have a maven project generated by webappcreator from google. i thought unit tests with gwttestcase should work out of the box? with sources not in classpath do you mean the eclipse way of sources (knowing were to look in debugging session, debugging normal tests is working fine)? Or do you mean the gwt-sources (declared in gwt.xml)? (i put all tests in same packages as the OUTs - that should be enough for gwt to find the sources?!) -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

hard time to get GWTTestCase to work
i just tried my first GWTTestCase but it fails. My setup is Eclipse/Maven
(not the happiest couple on the planet) - the pom was initially generated
by gwt-tool (webappcreator?). I use MVP,gin, guice (testing views is not
#1 priority but i want it to work).
Normal Unit-Tests work just fine.
But with GWTTestCase i got different kinds of trouble:
if i try it with Eclipse' run as GWT Test i got:
com.google.gwt.junit.JUnitFatalLaunchException: The test class
'client.view.DynamicLayoutViewImplTest' was not found in module
'...integration'; no compilation unit for that type was seen

(The Test is in same package as the view, the module used inherits the
normal module but it includes all permutations)
If i run mvn test i got a much bigger exception: for some reasen the app
is deployed on jetty together with all server side stuff and i get an
guice-error!? mvn gwt:test does absolutly nothing. The first question is:
is this a source-code problem or a configuration problem or both? Here is
the source:
public class DynamicLayoutViewImplTestGWT extends GWTTestCase {
@Override
public String getModuleName() {
return ...Integration;
}
private DynamicLayoutViewImpl testObject;
@Before
public final void init() {
AdbResources resources = GWT.create(AdbResources.class);
testObject = new DynamicLayoutViewImpl(Unit.EM, resources);
}
@Test
public final void testIt() {
System.out.println(here);
}
}
as you see i just tried to get an instance of my testobject.
thx in advance
(i also tried gwt-test-utils is also failed)

List or ArrayList/concrete type
at the beginning of my gwt adventure i read somewhere that it is better to use concrete classes for interfaces like lists, because the gwt compiler must generate java script for every kind of list. Is this (still) true? I asked because by using arraylist/concrete types everywhere on client side yields a lot of loose coupling warnings from sonar and beside this it is the absolute opposite of the make-(gwt)-code-more-testable-by-using-interfaces-as-much-as-possible-philosophy. thx in advance -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

loading an image
i try to get an image displayed that is retrieved from an url. my first
(false) attempt was not respecting the asynchronous behavior so it only
worked in hosted mode:
Image image = new Image(someURL);
view.setImage(image);
but this failed in real mode. so i googled around (besides wrong
exampleshttp://examples.roughian.com/index.htm#Listeners~LoadListener and
this http://code.google.com/p/gwt-image-loader/ ) i found the problem: a
have to listen to load event. So i changed my code to this:
image = new Image(url);
image.addLoadHandler(new LoadHandler() {
@Override
public void onLoad(LoadEvent event) {
view.setImage(image);
image.setVisible(true);
}
});
the problem is that the event is never been fired or at least onLoad is
never executed. I also tried to addHandler before setting url. The url it
self works fine (browser is displaying the image) and log shows positive
image response:
response : HTTP/1.1 200
Content-Type: image/png
graphdata : [B@12505f5
so how to correctly load/display an image in gwt?
thx in advance

ie8 browser compatibility - big issue
i just installed ie8 to check compatibility of my gwt application. user.agent property is set as follows: set-property name=user.agent value=gecko1_8, safari, ie6, ie8, ie9, opera / the app works fine on chrome and ff but fails on ie8: - on left side of the app a tree (some hundred items) should be displayed but in ie8 this region keeps empty. Other views are displayed on west side (by changing to another place) but if i go back to the activity with tree the old view remains on west side. so i am unsure if this issue is related to activities/places or to the tree or to both. - the second issue relates to a tab-bar with 2 tabs - it isn't displayed So why the app doesn't work on ie8 (why i have to ask such a question for a gwt app?)

what happens on deployment of gwt app (using guice) - what lines of code are executed
on deploying my gwt web app i noticed that some code of server side is executed. But i have no idea what code is executed or how to control the code that is being executed on deployment. So how does the bootstrapping/deployment work in general and in the special case of a gwt app that uses guice (i don't know if this is a general web-app question or a gwt question or both)? (probably all classes bound to singletons are instantiated?) At the end i want to write a class/ o couple of methods that check server configuration and external data sources and log their results - some (bad) results should cause an abort of deployment. thx in advance -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: What is current state/fix of/for deprecated PlaceController constructor
since the beginning of using activities i asked myself why some dependency injection examples injected an eventbus and don't use the one that start() delivers. i thought that the pattern - inject all stuff you need.

VerticalPanel differently rendered on FireFox and Chrome
if i add some stuff to a verticalPanel nested in a SimplLayoutPanel(100%h,100%w) the result is very different on different browsers: chrome don't use the 100% and sticks all stuff in VP together. Firefox(6) and IE(6) use all the space to layout the stuff inside VP. Why does this happen? The main reason to chose gwt was to get rid of such problems. So if a table with 100%(i think that is the html translation of my VP) is rendered differntly, gwt should use a different translation to get same results, shouldn't it? the other question is how to get the same result on all browsers - i want the result of chrome: all stuff should stick together vertically arranged. thx in advance -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: What is current state/fix of/for deprecated PlaceController constructor
thx for clarification jens. my problem is that i use the event bus within some activities outside of start(..) and there i always should use the bindary-One. So in such activities i have two different EventBuses. the bindary-One is imported the other one is explicitly set in start method. And to be sure that an activity never uses /imports the wrong EventBus i did it in all activities. (someone could add some code to an activity that uses/needs an eventbus and if at this point in time the wrong import is present (because the start -method needs it) it won't work - some injector error will occur) -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

What is current state/fix of/for deprecated PlaceController constructor
I just updated to gwt 2.4 - to get the data grid (very nice). but no my PlaceController construction is deprecated. I read around here but can't find a good solution for this issuehttp://code.google.com/p/google-web-toolkit/issues/detail?id=6653. (is it even an issue?): if i update my PlaceController construction (in GinModule), all Activity's start()-methods start to cry (they wan't the old EventBus). They get their EventBus via ActivityManager, but the ActivityManagers are also constructed with new EventBus. So it seems it's a Problem of AbstractActivity isn't it? For he Moment i have decided to keep the deprecated constructor (good idea?). But what would be the long term solution for this? Will there be a fix? Or is there already a fix? thx in advance -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: What is current state/fix of/for deprecated PlaceController constructor
my problem is (the same problem as the others have/has?) if i change the event bus in GinModule all other instance get the new event bus. But now nobody (for example the activity manager) could call start(..., OldEventBus) because AbstractActivity's (com.google.gwt.activity.shared.AbstractActivity) start-method needs the eventbus from the old package. (to make it short if i switch to new event bus in ginModule the compile fails - i'don't want this :-)) the question is what to do (in http://code.google.com/p/google-web-toolkit/issues/detail?id=6653) they talked about editing activity source code or providing an own activity. but i guess thats not the official solution to lift an gwt app (2.3 using activities) to 2.4?! so how to implement an Activity in gwt 2.4 (i guess com.google.gwt.activity.shared.AbstractActivity should not be used?)? -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: What is current state/fix of/for deprecated PlaceController constructor
Thx Thomas,
The activity has no dependency on the singleton/global event bus, and the
one passed to its start() method doesn't come from GIN; so what's the
problem?
I think that's wrong in my case. ActivityManagers are provides this way in
my code:
@Provides
@Singleton
@Named(ContentArea)
public final ActivityManager getContentActivityManager(final
ContentMapper activityMapper, final EventBus eventBus) {
return new ActivityManager(activityMapper, eventBus);
}
The eventBus is provided
via bind(EventBus.class).to(SimpleEventBus.class).in(Singleton.class); At
the Moment i change the package the compilation fails for my activities
(another question is why new ActivityManager is accepting eventBus from
both packages).
Correct me if i am wrong: you suggest to give activity's start method the
old eventbus (but this one shouldn't be used). but because the activity
managers are calling the start method with their eventbus i have to provide
activitymanagers constructed with the old eventBus? (i don't really
understand the code you provided, is injector.eventBus() the old or the
new EventBus)

Re: What is current state/fix of/for deprecated PlaceController constructor
OK, let's start from the beginning: what do you mean exactly by the
compilation fails ? Java compilation ? GWT compilation ? where exactly and
with which error ?
Good Idea (an Thx for your patience - again):
If i change the binding of EventBus (
bind(EventBus.class).to(SimpleEventBus.class).in(Singleton.class);) from
old to new package in my clientModule (Gin) the deprecated warning in
@Provides
@Singleton
public final PlaceController getPlaceController(final EventBus
eventBus) {
return new PlaceController(eventBus);
}
will disappear but on gwt-compilation i'll get following error (maven
build):
[INFO] Compiling module de.stalabw.zensus2011.adb.AuswertungsDB
[INFO][ERROR] Errors in
'C:\WorkspaceADB\AuswertungsDB\target\.generated\de\stalabw\zensus2011\adb\client\gin\ClientInjectorImpl.java'

so what's the problem?

Re: What is current state/fix of/for deprecated PlaceController constructor
i guess i got it and saved my day -again. i just eliminated all old(and changed where necessary) imports and put com.google.gwt.event.shared.EventBus in each startMethod. but i have some bad feelings about that - some tests call the start methods. at the moment start(panel, new com.google.gwt.event.shared.SimpleEventBus()) works (because i know that the methods don't use the event bus - all are using the eventBus injected on construction-time) - but this could fail. so either i use only the old eventBus in Tests (where possible) or wrap it like the managers do in a resttableEventBus? - this solution feels like a workaround?! i think in future there must be an new AbstractActivity with correct start-Method (probably a 1.4AndUpActivity ;-?) -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: Gwt-App totally blocks Browser-UI
thx for the info jens, do you say there is no way to keep the browser responsive but to do less work/ transfer less data on/to client? is there at least a way to keep browser responsive if browser has to do much work/logic? if i understood it right: transfer much data is worse than to do much work on client side? so all efforts should go into reducing data amounts transfered to client? but lets assume for a moment that the rpc-call isn't the problem but the logic that handles the data received. could this cause a freeze of the browser? if yes how to avoid it? probably by using schedulInterupted? how to use it? or how to optimize the view in the way you suggested? At the moment the view shows the filtered tree and keeps an unfiltered tree to provide the tree faster if user clears the filter/resets the tree. the tree rendeing and realtime filtering is very fast - i think no incremental command is necessary. the only problem is the first loading/rendering of the tree - the tree is submitted in an very special data structure (arrayList, composite pattern) that makes live filter as fast as it is. i could try to create this structure on client side (more logic less data)... -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: problems with loading stuff/bootstrapping onModuleLoad triggered by an event
ok, thx thomas it begins to become clearer,
my code attached don't use scheduler, thats right. meanwhile (thx to you
thomas) i played with Scheduler and Timer. The current code looks like:
public void start() {
Timer timer = new Timer() {
@Override
public void run() {
if (ttReady auReady) {
continueStart();
this.cancel();
}
else {
System.out.println(waiting: + ttReady + +
auReady);
}
}
};
timer.scheduleRepeating(1000);
}
but the feeling about this code is not better than the feeling with my
infinite loop. i think the problem is, that i don't really understand the
backgrounds - especially the scheduler. could you please show me some
sample code for my special problem (how should start() look like?) or give
some reference to docs explaining the scheduler/the model behind it?

Gwt-App totally blocks Browser-UI
At the start of my App the Browser has to load some stuff and create some data objects (Trees). The Problem is, that this blocks the the whole browser (no tab switching no reaction on user interactions, even my animated loading.gif is not loaded/animated). In swing applications the is a SwingWorker to keep the ui running - for example to display a progress bar. But how to achieve this with GWT? My guess is to use Scheduler some how?! I want to get the loading more in background and keep the browser more responsive. But how to do this? thx in advance -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: problems with loading stuff/bootstrapping onModuleLoad triggered by an event
i found a bit of info about scheduler
herehttp://stackoverflow.com/questions/5131086/using-the-gwt-scheduler.
now i got:
private boolean tryToContinue() {
if (ttReady auReady) {
continueStart();
return false;
} else
return true;
}
public void start() {
Scheduler.get().scheduleEntry(new RepeatingCommand() {
@Override
public boolean execute() {
return tryToContinue();
}
});
i used scheduleEntry because of Javadoc: This type of command is
appropriate for instrumentation or code that needs to know when something
happens.
But i am unsure about my implementation/ my understanding about scheduler -
is the code above correct?

Re: problems with loading stuff/bootstrapping onModuleLoad triggered by an event
THX for this explanation Jens! the problem i have with the code you suggested is: how to implement //wait as stated before my first implementation with an (infinite) while loop could block the whole browser. So whats about the other kinds of scheduleXXX? Whats about the code i showed above - using scheduleEntry? According do Javadoc scheduleEntry is exactly what i need, but i am unsure how to use it. -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: Gwt-App totally blocks Browser-UI
thx, are there any examples how to use scheduleIncremental? I don't want/can't to split the work that has to be done manually but i want to give the browser a chance to do other stuff - is it possible to interrupt a task for some time? In my case the main work has two parts: loading of data (one ArrayList containing the tree structure) and creating a tree widget with it. but splitting the work in this two parts wouldn't be enough - the second part alone could block a browser on a slow machine for up to 10seconds - very bad.

Re: problems with loading stuff/bootstrapping onModuleLoad triggered by an event
Thank YOU Thomas, i guess now i got it - i don't have to schedule the data-loading but all the other stuff that need to be properly initialized, right? Thanks for your patience (i is probably not the first time i say thx for your patience :-)). i just wanted jens to ask what happens if dataReady is not ready - i guess nothing? but for interest: my code above (using scheduleEntry) would work, wouldn't it? i'll will refactor my code -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: problems with loading stuff/bootstrapping onModuleLoad triggered by an event
At the moment i read your last post/ understood the problem i knew that you
tried it several times - i saw all your vehement efforts to get it into my
brain (but some times brains don't want to see :-) ).
i just refactored my code - in fact i haven't changed much (i already had
some scheduler stuff in my code). Because all my tasks are done on
construction time (gin injected stuff, ApplicationManager registers himself
to onTaskDoneEvents in constructor) i got rid of the public start()
method. Now i only have a private start called in the way you suggested it:
...
@Override
public void onTopicTreeLoadedEvent(TopicTreeLoadedEvent event) {
ttReady = true;
start();
}
..
@Override
public void onAdminUnitsLoaded(AdminUnitsLoadedEvent event) {
auReady = true;
start();
}
...
private void start() {
if (ttReady auReady) {
Scheduler.get().scheduleFinally(new ScheduledCommand() {
@Override
public void execute() {
// set up activity managers
sidePanelAreaManager.setDisplay(contentArea.getWestSideArea());
breadCrumbAreaManager.setDisplay(contentArea.getBreadcrumArea());
contentMenuAreaManager.setDisplay(contentArea.getContentMenuArea());
contentAreaManager.setDisplay(contentArea.getContentArea());
// insert dynamic layout in static layout
staticView.getContentArea().setWidget(contentArea);
contentArea.setDefaultLayout();
historyHandler.register(placeController, eventBus,
startPlace);
historyHandler.handleCurrentHistory();
currentPlace = placeController.getWhere();
}
});
}

Re: problems with loading stuff/bootstrapping onModuleLoad triggered by an event
so at the moment i delay it (the whole continueStart()) untill some events
occur. And you propose not to delay it with scheduleDeferred (until 2
events occurred) but with scheduleFinally? Or how the code shoul look like?
at the moment it is:
...
new SchedulerImpl().scheduleDeferred(new ScheduledCommand() {
@Override
public void execute() {
while (!(ttReady auReady)) {
//bad i know
}
continueStart();
}
...
private void continueStart() {
// set up activity managers
sidePanelAreaManager.setDisplay(contentArea.getWestSideArea());
breadCrumbAreaManager.setDisplay(contentArea.getBreadcrumArea());
contentMenuAreaManager.setDisplay(contentArea.getContentMenuArea());
contentAreaManager.setDisplay(contentArea.getContentArea());
// insert dynamic layout in static layout
staticView.getContentArea().setWidget(contentArea);
contentArea.setDefaultLayout();
currentPlace = placeController.getWhere();
eventBus.addHandler(PlaceChangeEvent.TYPE, this);
historyHandler.register(placeController, eventBus, startPlace);
historyHandler.handleCurrentHistory();
// currentPlace = placeController.getWhere();
// eventBus.addHandler(PlaceChangeEvent.TYPE, this);
}
so please tell me what lines to move where or what lines to change
thx in advance

Re: problems with loading stuff/bootstrapping onModuleLoad triggered by an event
i made an (nearly)minimal example showing this problem. it is a simple
sandbox app where i made some experiments with RequestFactory and
Activities and Places (no DI, no Gin). The crux is now, that onModuleLoad
is starting an AppManager.start(). The AppManager shows only wait until
data is received and event is fired. I f event is received all the
activities/places machinery is started - but here is the problem: no
activity is started but PlaceChangeEvent is fired. But all later
PalceChangeEvents are handled correctly. So what to do to reproduce:
Start the app see wait, wait see received data (the data sending
service waits 10seconds) - no activities started.
Change id in url from 1 to 2 or vice versa - activities are started
correctly.
or change start() in AppManager and run continueStart() directly:
public void start() {
//if (dataReady) {
continueStart();
//} else {
//appLayout.add(new Label(wait!));
//}
}
So why the activities are not started on first load? what happens here?

Re: problems with loading stuff/bootstrapping onModuleLoad triggered by an event
that was my first guess but i debugged into ActivityManager's- register event code. all activity managers are instatiated and have themselve registered on placechange events before the deferred handleCurrentHistory() occurs. Or the other way around: if i do not defer the start all is working fine. it seem only to work if all stuff happens inside onModuleLoad(). and it seem that problem only occur if handleCurrentHistory() happens after onModuleLoad and all the binding and instantiation in onModuleLoad.

how to get speedtracer to work with eclipse/tptp
some weeks ago i tried speed tracer in chrome for my gwt app (eclipse/maven). but only sseing the javascript/html side of the coin doesn't really help. now i installed TPTP for Eclipse (my idea was i just click profile as MyWebApp) but i found profile as speedtracer. So clicked it and set up chrome browser in eclipse (including --enable-extension-timeline-api). Eclipse compiles it, eclipse showed up the url and launches chrome with it, chrome displays Loading Speed Tracer for:http://localhost:/MyWebApp.html; but nothing else happens! if i enter the url directly my app is loaded but not completely - it stucks somewhere. So how to set up Eclipse/(Maven)/Speedtracer/Chrome to get profiling to work? thx in advance -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: problems with loading stuff/bootstrapping onModuleLoad triggered by an event
at the moment the whole continueStart is deferred at the end of this
continueStart handleCurrentHistory() is called, after instantiating
activity mappers and managers. Before that (on construction time of
AppManager) EventBus and PlaceController are instantiated.
you could look in the code i attached in 2nd post. which lines of code
should be moved where?
(i still don't understand why it works with out the delay but fails with
delay)
in my real code i tried also to delay the start with a Timer - no matter
how long the start is deferred it works fine. but as soon as continueStart
is run after onModuleLoad() - eventBased delay it fails. in meantime
deferred it synchronously by implementing start() like this:
new SchedulerImpl().scheduleDeferred(new ScheduledCommand() {
@Override
public void execute() {
while (!(ttReady auReady)) {
System.out.println(waiting);
}
continueStart();
}
});
This is working fine. The time of delaying is the same as before: as soon
as tt and are become ready. but for interest i want to know/understand what
is happening here.

strange JSNI Exception Something other than a Java object was returned from JSNI method ...: JS value of type boolean, expected java.lang.Object
our gwt produces every few seconds a strange exception: java.lang.IllegalArgumentException: Something other than a Java object was returned from JSNI method i googled around and find that this could be related to autoboxing (in this case probably boolean-Boolean: JS value of type boolean, expected java.lang.Object).

problems with loading stuff/bootstrapping onModuleLoad triggered by an event
the scenario is as follows (i use gin): - onModuleLoad instantiates a ApplicationManager and runs start() on it. - ApplicationManager sets up all activitymanagers and the layout, gives every manager some display area, sets up history handler and start history (historyHandler.handleCurrentHistory();) all is running fine but i want the application manager to defer the loading until an event (data-loaded-event). so i make the manager listen to it and all the setup-stuff is done in a new method continueStart(); called on this event. the former start() (called in onModuleLoad) just displays a loading widget. but now no activity is started. i debugged into the code. it seems that with this deferred loading the ActivityManagers don't hear the PlaceChangeEvent fired by historyHandler.handleCurrentHistory(); (The Eventbus emitting this event is the same the ActivityManager registered on) So what's going on here? my only explanation at the moment is, that this could be related to the fact that all the application setup stuff happens after onModuleLoad has finished (it only calls start(), and in background applicationManager is waiting for an event and does the reals setup after onModulLoad()) so what to do - thx in advance -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

How to get @Prefix value from an Place.Tokenizer? or how to set via clientbundle constants?
My app uses activities and places. All my places' tokenizers have prefixes to make bookmarks more readable. instead of calling PlaceController.goTo(new Place) i often use (inline)hyperlinks that point to another place or state - i think it is more readable and transparent for the user. The problem is: on generating /building those links i need the prefix of the respective place, at the moment those classes have a string constant with the prefix' value - a bad thing, will break as soon as someone changes the prefix. at the moment i see two ways to get rid of the magic string constants in the link-building class: - let the place implement a getInlineLink() - Method(probably specified within an interface), the prefix is to be set as an static constant within the place - get the prefix somehow - is there a way to get the value of prefix of a place'tokenizer class? - provide the strings via client bundle constants interface - another way or is this all bullshit ? so what do you suggest? thx in advance -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

how to test presenter that is activity
On of the main advantages of MVP-patrtern propagated is testability because if implemented correctly there is no need for GWTTestCase. But if i use MVP in conjunction with activities places - meaning presenters become activities - this advantage seem to gone?! Beeing a presenter and activity at the same time means knowing something about PlaceController - to go to other places or to deserialize the state of current place. (If PlaceController is involved the need for GWTTestCase arose.) At the moment i see some alternatives: - testing the old way with GWTTestCase - separating activity and presenter (separating navigation logic from business-logic, the pattern is know MVPA) - make activity more testable (how? give a null-PlaceController in constructor?) My Question is: Is there a best or at least good practice to test/implement such presenters? (the first 2 alternative are the worst in imho) -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: how to test presenter that is activity
thx i already use gin. but how to get a testable PlaceController - Placecontroller is a class not an interface? my only idea is to give null? -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.
