Question on ConditionalProperties
Hi!
I was just checking the Wiki page on Conditional Properties, and I think an
example is off by one.
Given:
define-property name=mobile.user.agent values=android, iphone,
not_mobile /
property-provider name=mobile.user.agent![CDATA[
{
var ua = window.navigator.userAgent.toLowerCase();
if (ua.indexOf('android') != -1) { return 'android'; }
if (ua.indexOf('iphone') != -1) { return 'iphone'; }
return 'not_mobile';
}
]]/property-provider
!-- Constrain the value for non-webkit browsers --
set-property name=mobile.user.agent value=not_mobile
none !-- Actually means NOR, in this case not safari --
when-property-is name=user.agent value=safari /
/none
/set-property
the text says instead of having [user.agent] * [mobile.user.agent] = 6 * 3
= 18 permutations, this will produce [user.agent] + [mobile.user.agent] =
9permutations.
As I see it, five of the possible user.agent values (i.e., everything but
Safari) will each produce a combination (for
mobile.user.agent=not_mobile), and when user.agent *is* Safari, it will
produce three combinations, for each mobile.user.agent value -- and that
comes out to 8, not 9. Am I missing anything?

A MVP widget within a View
Hi! I've been playing with the MVP framework, and I'm thinking about designing a widge (in MVP fashion, naturally!) and including it within another MVP form.

Re: New book, ESSENTIAL GWT
Hi! This book is geared towards GWT 2, including all its new features. I cover items such as UiBinder, code generators, deferred binding, MVP, etc. Quoting from the preface of the book: Chapters 1 through 3 deal with the basic setup for working with GWT. After considering the main reasons and objectives for using GWT, we shall study what other tools are required for serious code development, the methodology to use, and the internal aspects of projects. Chapters 4 and 5 are really a backbone for the book, for they deal with the basic design patterns that we shall use for building the User Interface. The code style and idioms that are developed here will be use throughout the rest of the book. Chapters 6 and 7 deal with communications with servers, either through RPC (to connect with servlets) or through direct Ajax (to communicate with remote services). Chapters 8 and 9 study how to add both JavaScript coding and third party APIs to your application. Together with the previous two chapters, everything that’s needed for mashing up services and getting information from different sources will have been covered. Chapters 10 and 11 deal with very common server related problems, such as security aspects, and file upload and download. Chapter 12 has to do with developing GWT applications that will be used worldwide, and covers both internationalization and localization. Finally, chapters 13 through 15 consider general themes such as testing GWT applications, optimizing their performance, and finally deploying them. Hope this helps -- and just ask away if it doesn't!

Window.alert(myme.howMany(0) + /
+ myme.howMany(1) + /

Re: MVP with GWT 2.0/UiBinder could be simplified
Hi! Personally, I do not use the HasX methods. The way I use MVP +UIBinder to create SomeForm is: * SomeFormView creates its widgets through UiBinder, which are in SomeFormView.ui.xml. SomeFormView implements SomeFormDisplay (see below) which is the interface that SomeFormPresenter expects. * SomeFormDisplay is an interface, that is implemented by SomeFormView; this includes getters and setters, but doesn't provide direct access to any widget. This interface also includes methods to define callbacks, which are used by SomeFormView when it wants to return data to SomeFormPresenter, or whenever an event occurs that needs be handled by SomeFormPresenter. Events are linked to these callbacks by using @UiHandler; the corresponding code just invokes the appropriate callback. * SomeFormPresenter receives a SomeFormDisplay object in its constructor; thus, it cannot interact with the SomeFormView except through the SomeFormDisplay interface. Just about the first thing SomeFormPresenter does, is create appropriate callbacks, and set them (through the SomeFormDisplay setSuchAndSuchCallback(...) methods). Is this explanation clear? Is this closer to what you expected? Best regards, F.Kereki -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: MVP + UiBinder, thoughts?
Here goes... I'm doing a simple form that allows you to browse all
cities whose names start with a given string.
The ui.xml file contains a textbox, a couple of buttons, and a grid;
the relevant lines are:
g:HTMLPanel
h1CitiesUpdater/h1
Start of City Name:
g:TextBox u:field=cityNameStart/
g:Button u:field=getCitiesButton text=Get Cities/
g:Button u:field=updateCitiesButton text=Update Cities/
hr /
g:FlexTable u:field=cg/
/g:HTMLPanel
The View includes:
@UiTemplate(CitiesUpdaterView.ui.xml)
interface Binder extends UiBinderHTMLPanel, CitiesUpdaterView {}
private static final Binder binder = GWT.create(Binder.class);
@UiField TextBox cityNameStart;
@UiField Button getCitiesButton;
@UiField Button updateCitiesButton;
@UiField FlexTable cg;
SimpleCallbackObject onGetCitiesClickCallback;
SimpleCallbackObject onUpdateCitiesClickCallback;
SimpleCallbackObject onCityNameStartChangeCallback;
@Override
public void setOnCityNameStartChangeCallback(SimpleCallbackObject
acb) {
onCityNameStartChangeCallback = acb;
}
@Override
public void setOnGetCitiesClickCallback(SimpleCallbackObject acb)
{
onGetCitiesClickCallback = acb;
}
@Override
public void setOnUpdateCitiesClickCallback(SimpleCallbackObject
acb) {
onUpdateCitiesClickCallback = acb;
}
@UiHandler(cityNameStart)
void uiOnChange(ChangeEvent event) {
onCityNameStartChangeCallback.onSuccess(null);
}
@UiHandler(getCitiesButton)
void uiOnGetClick(ClickEvent event) {
onGetCitiesClickCallback.onSuccess(null);
}
@UiHandler(updateCitiesButton)
void uiOnUpdateClick(ClickEvent event) {
onUpdateCitiesClickCallback.onSuccess(null);
}
The Presenter includes:
public CitiesUpdaterPresenter(
final String params, final CitiesUpdaterDisplay
citiesUpdaterDisplay,
final Environment environment) {
// ...
getDisplay().setOnGetCitiesClickCallback(new SimpleCallbackObject
() {
// ...code to run, when the Get Cities button is clicked
});
getDisplay().setOnUpdateCitiesClickCallback(new
SimpleCallbackObject() {
// ...code to run when the Update button is clicked
});
getDisplay().setOnCityNameStartChangeCallback(new
SimpleCallbackObject() {
//...code to run whenever the CityNameStart field changes
}
So...
* the Presenter is injected with the Display (View) to use
* the Presenter injects three callbacks into the View
* the View uses @UiHandler to define three handlers
* the handlers just call the callbacks that were set by the Presenter
Note that SimpleCallback is an extension of AsyncCallback.
I hope this is clearer; I deleted as much code as possible, to make
the example simpler. Please ask again if you have any doubts or
questions.
Best regards,
F.Kereki

Re: RequestBuilder problem
That's the Same Origin Policy in action -- IE8 is more lax than

Re: MVP + UiBinder, thoughts?
I also gave a thought to your method, but in the end opted out... but I guess it's where you are heading. In the same way that the View implements Display, an interface defined in the Presenter class, Presenter could implement Execute, an interface defined in the View class. The View should have a method allowing injection of the Execute object; the Presenter would this self injection in its constructor. Then, whenever any event happened, the View handler would do getExecute ( ).someMethod( ). You would do away with all anonymous classes, and each class (View, Presenter) would implement an interface defined in the other class. The symmetry breaks down a bit because you cannot inject each object in the other through their constructors (obviously!) Is this along the lines you were thinking? -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: MVP + UiBinder, thoughts?
I use @UiHandler to define a handler that will call a callback, which the Presenter injects into the View.

You can getSuggestOracle(...) but you cannot set an oracle unless you do it through its constructor, and this asymmetry poses a problem. In MVP, the View shouldn't deal with the oracle complexity; its logic should be a Presenter responsibility, so the View cannot create the SuggestBox. On the other hand, since the Presenter shouldn't be creating widgets, there's a problem... who creates the widget? I think there should be a setSuggestOracle(...) method; thus, you could create an oracle-less widget (possibly via UiBinder) and later attach a Presenter-provided oracle to it. What do you think? Am I missing anything? -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group. To post to this group, send email to google-web-tool...@googlegroups.com.

Re: Communicating between gwt composites
This sounds like you could use an Event Bus, also called Event Collaboration pattern; see http://martinfowler.com/eaaDev/EventCollaboration.html for more on it. Basically, the idea is that whenever something interesting happens, a Composite raises an event, which all other composites get a chance to process. Most composites will just simply let it pass, but those who find it relevant, can update themselves. -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: SuggestBox MVP problem
If I understand it correctly, that poses a chicken-and-egg problem, because the Presenter constructor requires a View, and the View constructor would require something created by the Presenter? With MVP, I first create a View, and then inject it into the Presenter. If the View requires an oracle, then I must create the Presenter first -- but in that case I cannot inject the View!? I solved this --and am not happy about it-- by (1st) creating the View, WITHOUT the SuggestBox, (2nd) injecting the View into the Presenter, and (3rd) having the Presenter create the oracle and provide it to the View, so the latter can add the missing SuggestBox. While this does work, it goes against UiBinder; the best I can do is to reserve a space for the SuggestBox, and I cannot get to use @UiHandler annotations. -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: SuggestBox MVP problem
Matt Moriarity's idea suggested another possibility: using @UiField (provided=true) and using a Factory method to actually deliver the widget to the view. I'll give it a bit more thinking; I want to make sure testing is still simple. -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

UiBinder Composite problem?
I want to include a composite object (a pair --Country and State-- of
related listboxes: whenever the user selects a country, the second
listbox is populated with that country's regions) in a UiBinder
created form.
The internal composite logic takes care of dealing with the Country
value change events. Whenever the country or the state changes, I want
to fire an event, so the UiBinder form will process it.
(Rationale: dealing with the two listboxes is an internal matter of
the composite object. The UiBinder form should not have to work with
either of the listboxes. But, the UiBinder form needs to be aware
whenever there's a change in the composite, for its own logic.)
FIRST PROBLEM:
@UiHandler(countryStateView)
void uiOnChange(ValueChangeEventObject event) {
onCountryStateChangeCallback.onSuccess(null);
}
produces a runtime error:
23:17:56.450 [DEBUG] [mvpproject] Rebinding
com.fkereki.mvpproject.client.citiesBrowser2.CitiesBrowserView.Binde
23:17:56.456 [DEBUG] [mvpproject] Invoking

23:17:56.463 [ERROR] [mvpproject] Field 'countryStateView' does not
have an 'addValueChangeHandler' method associated.
How do I associate a value change event handler to the composite?
SECOND PROBLEM:
What code do I have to write in order to fire the needed event?

Re: UiBinder Composite problem?
In full validation of Murphy's Law, a few minutes after posting my
questions, everything clicked and my code works.
Now, just in case I'm doing something wrong --or at least, in a not-
too-good way-- here's what I did:
In the definition of my Country-and-State view, I added
public class CountryStateView extends Composite implements
HasValueChangeHandlersObject
and I implemented the required method with:
@Override
public HandlerRegistration addValueChangeHandler(
ValueChangeHandlerObject handler) {
return addHandler(handler, ValueChangeEvent.getType());
}
Whenever the country or state listboxes changes, I do:
ValueChangeEvent.fire(...the.composite.object..., null);
and finally, in the UiBinder created form, I wrote
@UiHandler(countryStateView)
void uiOnChange(ValueChangeEventObject event) {
// ...do whatever needs be done...
}
This is working perfectly (at least to my eyes!) but I'd like to know
if it could/should be done in a better way.

One class, several UiBinder templates
Hi!
Say you want to have two templates for a single class.
You can have
@UiTemplate(firstTemplate.ui.xml)
interface Binder1 extends UiBinderHTMLPanel, yourClass {}
private static final Binder binder1= GWT.create(Binder1.class);
@UiTemplate(secondTemplate.ui.xml)
interface Binder2 extends UiBinderHTMLPanel, yourClass {}
private static final Binder binder2= GWT.create(Binder2.class);
but how do you specify to which template does each @UiField belong? If
you just write
@UiField SomeWidgetClass someWidget
UiBinder will object unless someWidget is found on BOTH templates.
Can this be done, or need I create separate classes for each template?

Re: UiBinder and FlexTable or Grid
The idea was that FlexTable and Grid hide the HTML code, and avoid any possible cross browser problems. If you go back to using HTML directly, you may have to deal with browser quirks on your own. Of course, with pretty simple HTML, that won't probably be a problem, but what I like about GWT is being able of forgetting HTML and JavaScript -- most of the time, at least.

In order to test UIBinder, I simply created a new uibindererror project (which ran perfectly well) but after just adding the single line inherits name='com.google.gwt.uibinder.UiBinder'/ to its gwt.xml file (and touching absolutely nothing more) it never ran again, and instead the development mode console showed: 00:01:00.605 [ERROR] Failed to load module 'uibindererror' from user agent 'Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.9.1.5) Gecko/ 20091103 SUSE/3.5.5-3.1 Firefox/3.5.5' at fkereki.desktop:44111 while the application console showed: 00:01:35.252 [ERROR] Unable to find 'uibindererror.gwt.xml' on your classpath; could be a typo, or maybe you forgot to include a classpath entry for source?

Re: super-source used to complete java.lang.Math?
Point 1 (create an issue on the GWT issue tracker) is done: see http://code.google.com/p/google-web-toolkit/issues/detail?id=4308 I'm not sure whether locally patching Math.java (and all other packages with missing static methods) would be a good solution; I understand it can work for specific cases, but it seems not to good. Of course, submitting the patch and having it accepted would be good, but could imply long delays, which wouldn't be acceptable if you have to solve the problem right now.
