Re: GWT 2.3 composite editor // setValue called twice
Hi Patrick, that's true, but it was an example only. You surely should do what you said but it's still unnecessary (and potentially harmful for the performance) to do this call twice (by the framework!), so I think it's a bug in GWT's editor code that should be fixed there and not be worked around by (application) developers.

GWT 2.3 composite editor // setValue called twice
Hi, unfortunately there seems to be no love for the issue I reported a while ago concerning the revamped editor code (starting w/ GWT 2.3) using Refresher & Initializer. http://code.google.com/p/google-web-toolkit/issues/detail?id=6336 Sub-editors' setValue() methods get called twice, which can be a very bad thing if you do something fancy/heavy in you setValue() method. But even for non-visible use-cases (like my trivial example w/ TextBoxes) it's unnecessary and a can harm performance.

Re: Eclipse plugin problem with OSX Java update 4?
Maybe you have to install the latest Java developer package from Apple

Hi, I'm playing around with CSS3's @font-face. It doesn't work with GWT 2.2's CssResource unfortunately.

Re: GWT 2.1 and Place with token
Hi Nicolas, often your places are "parameterized", think of a detail/edit screen for example that needs the model's id. The token is a generic way to provide additional information (via the URL) to the place (i.e. the activity/-ies), i.e. "#editFoo:42". You can of course re-use one place to dispatch to several activities based on the token. See the (currently not used) for ProxyPlace and ProxyListPlace in the Expenses sample for an example.

Of course you are right -- I wasn't precise (and thus wrong :) What I meant (and "hate" :) is that you're not allowed to override methods and that there is a "one interface to one JSO" constraint (since GWT 2.0). I like to have my domain models implement something like EntityModel (a custom interface declaring Integer getId() and String getrLabel() for example). That way, I can really simple build/populate things like ListBoxes etc. GWT 2.1's ProvidesKey et al. gives us another (and more flexible) solution for these problems though. > That's why I created JsCollections a while ago with a set of > JsArrays.toArray() methods that copies the JsArray into an array in > DevMode but just "casts" it in prod mode (i.e. no single overhead once > compiled to JS). I used to do something similar. For dates and date-times as well (as these types are Strings in the JSON requests -- this works best for me at least). But I must admit, I'm lazy and I just (would) prefer to not think about these conversions and "just use" Lists, Dates etc. as I do on the server side.

I used to use overlay type heavily (returning JSON from a Spring
MVC/Jackson backend) and it worked quite well. Although I found it
quite limiting to be unable to model "real" class hierarchies (JSOs
must not be subclassed). I really do this a lot on the server side. I
also really like to use the enhanced for loop for Lists and just do a
new Foo() instead of some tedious Foo.create(). Last but not least I
don't have a "Generate getters/setters" in Eclipse for my JSOs :)
All this led me to write a Generator which inspects my models ("real"
beans) and emits JSON mapping code handling simple properties, object
graphs and collections. That way I can work with real beans and
collections of beans in my (business) code and do the mapping from/to
JSON in my service/DAO layer (still sending/retrieving JSON to/from my
backend).

GWT 2.1 cell table paging bug?
AbstractPager uses HasRows#getVisibleRange()#getLength() to obtain the page size. This doesn't seem to be a good idea as you can see in the Showcase exmpale (Cell Widgets/Cell Table [1]). This table gets populated with 250 entries and shows 15 per page. Now click on the "next page" button. You go (correctly) all the way to showing "226 - 240". But the next click switches to "236 - 250". I expect the table to go to "241 - 250" (and thus showing only 10 rows). But it gets worse: If you now start to navigate back, the display range is moved by this offset. So you reach "11 - 25" and then "1 - 15"?! I don't think this behaviour is intentional. At least the "go to last page" and "go to first page" buttons work properly (showing "1 - 15" and "241 - 250"). Bug?

Flashing/collapsing CellTable
Hi, I'm looking at the new data presentation widgets in GWT 2.1 and I mostly like what I see :) I have one problem with the "workflow" updating/paging a cell table though. I'm using a (heavily) customized version of AbstractProxyListActivity from the Expenses example and I just don't understand why HasDataPresenter is clearing the table content while loading the next/previous page. Instead of the current rows, a loading indicator is displayed (with different a height resulting in a collapsing/expanding table). I already filed a bug (5487) to make this customizable (at least via sub-classing). For the moment, I deactivated this loading indicator (I show a application-wide indicator in my app and don't want to show inline indicators). This deactivation makes the "flashing" even more obvious. I want my "old" rows to be there until they are replaced by the "new" ones, maybe overlayed by some "glass" and a loading indicator -- but not replaced! That way the table doesn't collapse and no "flashing" is visible in the ui. What's the reason for HasDataPresenter to clear the row data in setVisibleRange? I try very hard to not show flashing and resizing elements my apps' UIs but set up everything correctly *before* adding it to the display list.

Re: GWT 2.1 hellomvp using GIN
Thank you Thomas, that's what I was thinking -- and I'm playing with a custom code generator already :) Just wondering what "they" mean with the GIN comments in the doc/code... In my pre-2.1 homegrown framework I use a code-generated presenter config based on a Ginjector (declaring all the getFooPresenter() methods annotated with location (place) and security informations). My presenters were singletons and were "started" with the actual Place. That way I could use GIN to (constructor) inject all my dependencies. I'm not sure if I like this 2.1-design (constructing activities with the actual place) which means I cannot use GIN to construct them. Maybe I make my activities extends some AbstractBaseActivity containing a setPlace(P place) method which is called in the ActivityMapper...

GWT 2.1 hellomvp using GIN
Hi, I'm looking at 2.1 (RC1) for the first time right now and I try to refactor the hellomvp sample to use GIN. Unfortunately, I have some problems with the places -> activities mapping.

ValueChangeEvent in DatePicker
Hi, I wrapped a DatePicker in a (custom) Popup and I like to hide the popup when a value is selected in the DatePicker. That's working great for "new" values, but if I don't change the value but click at the same, highlighted (and thus already selected) date, no ValueChangeEvent is fired. I guess that's desirable most of the time, but not for me :) To solve this, I had tried to override DatePicker#setValue -- but it's declared final :( So I tried to subclass DefaultCalendarView and override onSelected in its inner class DataCell. But again no luck as DefaultCalendarView is final... Ok, last resort, I copied the code of DefaultCalendarView into MyCalendarView (arrg) -- and it's even worse... Since CellGridImpl is package-private, I had to move MyCalendarView to com.google.gwt.user.datepicker.client :((( I can't tell you how dirty I feel by this "solution" :) Do you have any idea how to do this w/out duplicating code *and* polluting the framework's namespace? Of course I could implement my own date picker (or take any of the open source ones) -- but the existing one is perfectly fine -- expect for this part...

Re: Injected CSS rules are evaluated after onModuleLoad/Widget#onLoad
Replacing globalResources.fooCss().ensureInjected(); with StyleInjector.inject(globalResources.fooCss().getText(), true); solves the problem as well! Thanks Dave. In the meanwhile, I wrapped my onModuleLoad code in a DeferredCommand() (mainly for an UncaughtExceptionHandler) and removed the DeferredCommand wrap in Widget#onLoad (as described in my previous post). That also works. Anyway, I use both modifications, deferring the onModuleLoad (mainly for the logger) and ensuring immediate CSS injection -- explicit is better than implicit :) Or do you see any (performance) issues with this approach?

Injected CSS rules are evaluated after onModuleLoad/Widget#onLoad
Hi, I tried to follow the best practices and moved my static CSS files from style-tags in the HTML-page to CssResources in a ClientBundle declared in my EntryPoint and injected in a static initializer. Unfortunately, this doesn't work for me because I do some element positioning in an onLoad-method of a Widget (which is contained in the UIBinder template of my EntryPoint). The calculations of the (relative) positions are wrong and I found out that the injected CSS rules are not evaluated until my positioning code runs. Profiling the generated JS code shows the following timing: - entering onModuleLoad - entering Widget#onLoad - leaving onLoad - leading onModuleLoad - injecting CSS Tested in Webkit and Firefox 3.5 on a Mac with Snow Leopard. If I defer the positioning (by triggering it manually via a Button click in the UI) everything works as expected. Is this a bug? Is there a work-around? I really don't want to move my CSS back to static files and lose all the great advantages from using ClientBundles. But I need my CSS rules parsed and evaluated *before* my code runs.

Re: Injected CSS rules are evaluated after onModuleLoad/Widget#onLoad
I found a "work around", I wrapped the positioning code in my onLoad() method in a DeferredCommand and it works. Is this the preferred solution for this "problem"?
