Re: Maintaining application state
I use an object called ApplicationModel, that is passed to every presenter on creation. It stores application state, as its name might suggest. It also fires off events whenever any of the presenters modifies one of its values, which helps keep the application in sync. Things like user roles and what the user has currently selected are stored in there. I should also mention that the ApplicationModel is actually handed off to the presenter as part of an ApplicationBundle, which is basically just a parameter object. It holds the model, the ApplicationNavigationControl, ApplicationEventBus, ApplicationFactory, etc. Wrapping it all up in the parameter object makes it really easy to add new application-wide bits. -Ben -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: Maintaining application state
The bundle is presenter-agnostic. It only contains application-wide state
and control objects.
I do have two classes of presenters in my application, however. Those that
get passed the ApplicationBundle are page presenters, and control the whole
screen (or at least the central content portion of it anyway). They are
created in response to navigation events. These, in turn, may create
component presenters and pass them specific bits of information, like an
instance of their view that was retrieved from somewhere in the main page
view interface, or a specific implementation of their model interface that
will play well with the rest of the page.
Something like this:
public XxxPagePresenter(ApplicationBundle bundle, XxxPageView view) {
this.bundle = bundle;
this.view = view;
this.model = new XxxPageModelImpl();
this.yyyComponentPresenter1 = new
YyyComponentPresenter(model.getYyyComponentModel(),
view.getYyyComponentView());
...
}

Re: How to unit test case on GWT server side class methods and how mock up the session inside the methods.
I do all of my server side work in little action objects. This allows you to remove your dependency on RemoteServiceServlet, and test only your code. So basically all of your server methods would look like: return new MyAction(getThreadLocalRequest(), clientArgumentBundle).perform(); Then you can mock out the request, session, etc, in your unit test, since they will just be arguments instead of class methods. -Ben -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: Development mode cross site RPC requests
I would think that the servlet would increase the performance of the application by a bit. XML parsing in JS can't be fun, or fast, for that matter. This assumes the latency between wherever you would run your application server and the target C++ backend isn't too high, though. Otherwise you are making a big triangle of a route, as opposed to simply back and forth. Probably still worth it, since then you can leverage awesome java XML parsing libraries. You may see some performance penalty for switching servers, I suppose.

Re: Have each element have its own unique id automatically
While it would cut down on the amount of line noise in the code, I see this as being somewhat fragile and I would avoid it in my code. Introducing a dependency between your code structure and your CSS would make it much more difficult to change things and refactor without breaking. I tend to hate anything that makes refactoring difficult, as I find the maintenance phase of an application is by far the lengthiest part. We actually did something similar to this in our codebase. We had CSS names auto-generating from the class name of the view/widget. While it did reduce some line noise, I found out that it made refactoring break all of the CSS. This made me not want to refactor things, which is evil. I've almost gotten rid of all of it by now, and will never go back. My current way of reducing this overhead is a simple Widget factory object. VerticalPanel mainPanel = new WidgetUtility().createVerticalPanel(cssClassOne); Not really auto-generated or anything, but it cleans up the code, and doesn't rely on any magic. -Ben -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: using SuggestBox with special Oracle and Suggestion - how to keep view humble
I ran into this issue as well - knowledge of the domain in the view. I
ended up getting around it by creating a delegate for the suggest oracle.
public class SuggestOracleDelegator extends SuggestOracle {
private SuggestOracle delegate = null;
public SuggestOracleDelegator() {}
public void requestSuggestions(Request request, Callback callback) {
if(this.delegate != null){
this.delegate.requestSuggestions(request, callback);
}
}
public void setDelegate(SuggestOracle delegate) {
this.delegate = delegate;
}
}
Then I wrap this in a HasSuggestions interface that lets you set the
delegate oracle from outside, and attach listeners and so forth. Seems to
work quite well.

Re: MVP dialog boxes
I've used approach #1 before (call a method on the view, it creates a
dialog) with good success. As long as it isn't complicated, that
works just fine, and I can't imagine it would be something significant
enough to require testing.
More recently, however, I've taken to Approach #3, whereby you have a
whole separate view/presenter for the dialog boxes. I go one extra
step and hide this behind a simple interface. I think this would work
a bit better for your implementation of the MVP pattern.
Snippet from inside one of my page presenters:
ChooseOneDialogSuggestion dialog =
this.bundle.getApplicationFactory().createChooseOneDialog();
dialog.addSelectionHandler(this.selectionHandler);
dialog.setOptions(ContactSuggestion.translate(result));
dialog.show();
The application factory is part of the resource bundle made available
to all of my presenters. The ChooseOneDialog interface hides the
implementation, but inside it is a fairly standard presenter/view.
The methods on the ChooseOneDialog interface simply delegate to the
presenter.
This allows me to keep this code separate and reusable, while at the
same time allowing me to mock it out for testing purposes, since both
the ApplicationFactory and the ChooseOneDialog are only known through
their interfaces. The bundle itself is actually a concrete class, but
all it does is contain interfaces, so it doesn't need mocking up.

Well I also use the Mvp pattern (custom one) and in the beginning I always
define methods HasXYZHandlers getXYZHandlerProvider() (e.g. HasClickHandler
getSaveClickHandlerProvider() ) and use these in the presenter. So I would
have chosen your second or even third approach.
But today I think it is better to perform simple tasks in the view itself
and use as much code provided by GWT. So as we use UiBinder we are able to
use the @UiHandler annotation which makes code much cleaner. Now our
confirmation boxes for cancel and delete actions/buttons are implemented in
the view itself and if the user wants to do an action the view calls a
corresponding method defined by a delegate interface which is implemented by
the view's presenter.
Example:
public interface MyPresenter extends Presenter {
public interface MyPresentersView extends Display {
public interface Delegate {
public void doCancel();
public void doDelete();
/* basically one method for every user action/event */
}
/* should be the first method to be executed */
public void setDelegate(MyPresentersView.Delegate delegate);
}
}
public class MyPresentersViewImpl extends Composite implements
MyPresentersView {
/* UiBinder stuff */
/* setDelegate method */
private void ensureDelegate() {
assert this.delegate != null : Delegate not set;
}
@UiHandler(cancelButton)
protected void onCancelClicked(ClickEvent e) {
this.ensureDelegate();
if(Window.confirm(Do you really want to cancel?)) {
this.delegate.doCancel();
}
}
/* other ui handler methods */
}
public class MyPresenterImpl implements MyPresenter,
MyPresentersView.Delegate {
/* implement doCancel() etc. */
}
I think this approach can also be done with dialog boxes although you need
a bit more code in the view for handling the dialog box. As we use
Window.confirm it is pretty simple. I like this pattern because the view
knows a delegate interface that contains a method for every user
action/event and can perform simple logic that do not have to be tested
before calling a meaningful delegate method that performs more complicated
logic. It also saves a lot of anonymous handler classes in the presenter.
Maybe you like this fourth approach ;-) But in general I would let the view
perform some confirmation logic that do not have to be tested and let the
presenter concentrate on complicated stuff.

Re: MVP dialog boxes
Yeah, essentially. The one presenter doesn't know the details of what
lives behind that interface, which is the important bit.
I do have some 'child presenters' in the application as well. Those
are concrete presenter classes that a page presenter will instantiate
to handle some subset of functionality on the page. They have a
corresponding 'child view' interface on the page view that they are
assigned to handle. Those presenters aren't shared much, though, so I
don't think the lack of an obscuring interface matters as much.
this.revenueSplitPresenter = new
RevenueSplitComponentPresenter(bundle,
this.model.getRevenueSplitModel(), this.view.getRevenueSplitView());
You could also do something similar to this for the dialogs. The view
is still separate, so testing will still be fairly simple. However,
you do lose out on the ability to mock out that particular subset of
functionality, which may or may not matter.

pattern this way so far, the view cannot delegate to the presenter; only
the
presenter can talk to the view...

Well I also use the Mvp pattern (custom one) and in the beginning I
always
define methods HasXYZHandlers getXYZHandlerProvider() (e.g.
HasClickHandler
getSaveClickHandlerProvider() ) and use these in the presenter. So I
would
have chosen your second or even third approach.
But today I think it is better to perform simple tasks in the view
itself
and use as much code provided by GWT. So as we use UiBinder we are able
to
use the @UiHandler annotation which makes code much cleaner. Now our
confirmation boxes for cancel and delete actions/buttons are
implemented in
the view itself and if the user wants to do an action the view calls a
corresponding method defined by a delegate interface which is
implemented by
the view's presenter.
Example:
public interface MyPresenter extends Presenter {
public interface MyPresentersView extends Display {
public interface Delegate {
public void doCancel();
public void doDelete();
/* basically one method for every user action/event */
}
/* should be the first method to be executed */
public void setDelegate(MyPresentersView.Delegate delegate);
}
}
public class MyPresentersViewImpl extends Composite implements
MyPresentersView {
/* UiBinder stuff */
/* setDelegate method */
private void ensureDelegate() {
assert this.delegate != null : Delegate not set;
}
@UiHandler(cancelButton)
protected void onCancelClicked(ClickEvent e) {
this.ensureDelegate();
if(Window.confirm(Do you really want to cancel?)) {
this.delegate.doCancel();
}
}

Re: Overriding panel's iterator() prevents clickHandler from being called.
Ah, I finally see what you are doing with that iterator. You are
using that to find and remove the item elements from the view.
What you are doing wrong is just abusing an existing method. You
generally try to not change the contracts of methods by overriding
them and assigning them different functionality, as it tends to break
existing code, and just be confusing.
There are many ways to do this kind of thing. The simplest would
probably be to define a new method getItemElementsIterator or
whatever else you want to call it, and return the flow panels iterator
that you want with that new method.

Re: Overriding panel's iterator() prevents clickHandler from being called.
Correct. You weren't abusing the iterator itself, you were abusing
the iterator method, which other things used.
You can still extend ScrollPanel, but just add your own bit of
interface on top of it. Like this bit of pseudocode.
class MyScrollPanel extends ScrollPanel {
private FlowPanel mySecretFlowPanel;
public void addThing(Thing x) { //add things to secret flow panel
here }
public void removeThing(Thing x) { //you get the idea }
public IteratorThing getThingIterator() { return
mySecretFlowPanel.iterator(); }
}
This is all a very view-centric way of doing it, however. I might
suggest reading up on the MVP pattern, which would help abstract away
the details of the panels entirely.

I meant it doesn't work when I override iterator().
Now, from what I understand, GWT relies on being to walk through the
panel tree using iterators() and that means I can't hide a panel
like that
(hence why it fails).
If I'm correct, then what are my options? Obviously, I can't use
ScrollPanel
because it implements the HasOneWidget interface. But then, if I
don't
extend ScrollPanel, how can I implement HasScrollHandlers: to do that,
I must implement addScrollHandler() which returns a
HandlerRegistration.
The problem is that, as far as I know, HandlerRegistration can only be
returned by
HandlerManager and its subclasses (DefaultHandlerManager) yet these
are deprecated
with no replacement :s .

Re: Best practice for to maintain Big project
If I am understanding you correctly, you worry about having to deploy the whole war for small changes, like a quick bugfix or the like. As far as I am aware, there isn't really a way to partially deploy a GWT application, like only those parts that changed. In theory, I suppose, you might be able to get away with just updating one of the JS fragments, assuming you knew which one held your changes, but that assumes a lot. Personally, I'd much rather deploy the whole thing for every change anyway. I wouldn't trust my fallible human brain to remember all of the individual code changes that need to go out. -Ben On Mar 4, 12:31 am, Jiunarayan jiunara...@gmail.com wrote: What I meant was when the project is compiled and you are project is ready.

Re: User roles in GWT applications
Depends on the situation, but in general its much easier on users if things they can't do/edit aren't shown to them. Or, alternatively, if they are shown, be shown with some visual indicator of restricted access. A panel full of blank values with no UI feedback is somewhat unintuitive. A panel with a shadowbox over it that says ADMINS ONLY, for example, makes a bit more sense, and will get you many fewer support calls.

Re: Method Reference Delegate or so
You could create a composite async request object. Its constructor
would take a list of special async requests, and it would execute them
in order. They would have to be special as you would need some way to
attach listeners to them to know when each is done (the base interface
doesn't provide for such a thing). As it was notified of each
success, it could kick off the next. Alternatively, you might try
kicking them all off, and whenever you get a pokeback from one of your
children you could see if they are all done.

Re: best practice for callbacks
Use unique click handlers. Then each clickhandler knows where it came from, so to speak, and can use a unique callback to update the appropriate widgets.

Re: Split points for method having return type other than void
You cannot return something from an async call like that. The work
will be done asynchronously, and the main program has presumably gone

If some object needs that result, a simple solution would be to pass
the object into the async method, and call a method on it with the

Re: Serious Bug or some Type Erasure I don't understand ???
After re-reading your post, I think I see the issue. While you didn't
post code for the three derived entities, I assume you are using
different type parameters for your SelectEntitiesEvent, and relying on
that to keep the events distinct. I do not believe that works either
in Java or in the translated JavaScript. As you mention, generics in
Java work on erasure, which means they don't really exist at runtime.
You would have to make them separate classes in order for the event
bus to treat them as distinct.

Don't get me wrong, CSS is kind of clunky, but I find it hard to imagine that this new solution would be significantly more elegant. -Ben On Feb 16, 8:31 pm, Kurtt kurtt@gmail.com wrote: GWT 2.2 introduces the Canvas, which is actually a 2D-API. This is exactly what Java Swing is based on. And we can create a LooknFeel class for GWT, which wraps a set of painting Canvas method. If we set the app a certain LooknFeel, when a widget is showing , the widget asks the LooknFeel to draw the UI for it according to its own state. This is similar to how the Java Swing pluggable LooknFeel works. benefits are that, 1) apps don't need CSS to define the look. For pure desktop-app developers like me, i find trouble in writing perfect CSSs. 2) Further, this guarantees the unified look across platform, while sometimes you have to write different CSS styles for different browsers. 3) Canvas supports drawing in the vector way. Nimbus in Swing is a LooknFeel based on vector-rendering. What do you think, guys? And, allow me to complain that the Canvas class under GWT 2.2.0 removed the support for IE 6/7/8. Even though some few effects are not displayed perfectly in IE and are 30x slower because the canvas tag is actually simulated, I need the Canvas in IE 6/7/8. Cause in china, the IE6/7/8 occupies a worth-noting market share (Microsoft executives: China is IE6 die biggest obstacle:http://www.amieindia.net/ viewtopic.php?f=244t=15183). -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: Production bugs that don't exist in development mode
So ... curious ... runAsync provides a callback to let you know when its done doing its thing. Why aren't you just using that to know when you can mess with the objects you have created?

Re: GWT runasync
Ewww. Icky. I'm not actually even sure if that works in GWT ...
If you really need them in a list, you could probably write a fairly
thin wrapper for your views. Im not sure what their interface is
like, but if they are in a list, they can't be specific types anyway.
Something like:
public interface ViewWrapper {
public void getView(callback);
}
Then you could fill your list with instances of that wrapper. So:
list.add( new ViewWrapper() {
public void getView(callback) {
//run async here
}
});
Your presenters could then go:
this.viewList.get(id).getView(new HeyMyViewIsReadyCallback(this));
Or something like that. I'd still voice a preference for a simple
factory object instead of a list, though. Then you could actually
have a specific type associated with the view. I suppose 200 methods
is a lot. 200 views is a lot too ... what evilness are you bringing
into the world?

Re: Formatting data - best on the server, or client?
My Right Thing is as follows. I will generally do some transformation work on the server side. Not to HTML, mind you, since that, to me, is purely presentation layer work. Rather, I will take the raw data and package it into lean records objects, and send the collection of those to the client. This work may mostly be done in SQL, or might mostly be done in code, depending on how your DAO layer is set up, and how much crunching is required. The collection of record objects is then shipped off to the client, where the display is taken care of. All of the values should already be pre-calculated in the record objects, so it just has to go about making them all pretty. So in this wall all work related to the contents of the report (the data itself, and its logical organization) are handled server side. But the server stays out of the pretty display business - thats purely client.

I've mocked up the result page in an HTML page with CSS and the formatting is fine for all browsers, but now I'm at something of an impasse in how to implement it. In a JSP world I'd just be populating the jsp file on the server and displaying the results in the browser. As it is, I'm using GWT (obviously... :) ) and I'm at a loss as to how to properly do this. I looked into the UIBinder class, which would give me the HTML template, but that means that the result set would have to be transmitted to the client and all the work done in the browser. I could use something like FreeMarker to format the results on the server, and then send back the generated HTML, which is the method I'm leaning towards, but that too seems sub-optimal. Any assistance on the right thing would be appreciated. -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: GWT Web Application testing...
I've only used Selenium for GWT client testing. It worked as we expected it to. The learning curve has a bit of a bump at first, due to the somewhat confusing way they name things and have you configure a test suite. Nothing to do specifically with GWT, mind you. I must mention that we have done a very limited amount of full on integration testing, however. Most of our testing is in the form of unit tests. -Ben On Jan 28, 10:32 am, SBParks scott.b.pa...@gmail.com wrote: Folks, Hello.

Re: GWT Activities, Places with Event Bus ??????
I solve this issue by having a single application wide event bus that is passed to all of the presenters in my application. I bundle it up with other application resources, such as a navigation control and an application wide model, and simply hand it to them in the constructor. So, if I wanted to do the same thing you describe in my application, I would simply have the controller that is listening to your updates push data into the application model, which would then fire off change events in the application event bus, and the other controllers would all be listening to those events. I haven't used the place/activity thing yet, so I don't know how those work exactly, but I would imagine there should be a way to hand them an application resource bundle on creation. -Ben On Jan 19, 7:59 am, SergeZ comp1...@gmail.com wrote: Hello everybody!

Re: Client en Server side validation
The correct thing to do, in my mind anyway (admittedly an odd place), is never trust a client and do your own validation of the data and operation requested. This contrasts with my professional experience, which has been that pretty much everyone just trusts the client and mindlessly follows its directions. I should mention that most of the applications I have dealt with are internal to an organization, so a rogue client isn't as big of a risk there. -Ben On Jan 19, 2:06 pm, Jeroen Wolff jeroen.wo...@gmail.com wrote: Hi, there has been a lot of discussion already in this group about validation and the frameworks that can help with it.

Re: GWT best practices and GUI libraries
Revenge of the Zombie Thread ... I am currently the owner/maintainer/code monkey behind a fairly complex GWT application. It is primarily data driven, but there is plenty of logic in the UI for role-based editing permissions, visibility, and coordinating different components of the application. It utilizes a centralized event bus and application model to keep everything on the same page. My experience with the widgets has been a pretty good one. The only thing that was lacking, but has been improved to a significant degree, was grids. With the new cell widgets, this is _almost_ no longer an issue. Static headers and sorting are really the only remaining things desired in these components. One minor caveat was the inability to directly re-use our business objects, as that project references DAOs (a horrible design decision, mind you, but I am stuck with it) and those don't work so well in JavaScript. We ended up writing a new business layer and translator objects. Not a small undertaking, but not difficult either. Also, client side calendar support sucks balls (to use a technical term) right now. Workable, but not nice. Overall, I've been pleasantly surprised with GWT. I normally despise web development, so that statement has a bit of weight behind it. I was able to apply more traditional Software Engineering principles and design patterns to the application (to the dismay of the web guy I was working with) and the environment felt very similar to developing a standard java swing application. As long as Google supports it (which, admittedly, is a bit of a worry), I will be happy to use it. Probably. Well, I might be angry, but that likely wont be GWTs fault. -Ben On Jan 18, 4:55 am, Kristjan kristjan.ko...@gmail.com wrote: Hi... I am also interested in questions below...

First a little background... I've used prior versions of GWT in a couple of applications, versions 1.5 and 1.7 I believe. In both cases what we found most lacking in GWT was an extensive UI widget library so in one case Mosaic was used and in another ExtGWT. The applications are not your standard web- site application, they are more like desktop apps redesigned for the web. I see that GWT 2.1 has built-in support via Roo for very easily creating a database app that has the basic UI for seeing and editing some database tables/etc. However what if one is creating an application that is not a simple database view/edit application but rather has lots of business logic that changes what is in the UI? I.e. the UI is not driven directly by what is in the database but is driven by business logic that is driven by both the user's choices and database data? So I guess my question is how does Roo help if its not the simple use case? Regarding UI widgets, has this improved in 2.1? I can't recall exactly what I was missing but it seemed GWT's UI library was a small subset of ExtGWT for instance. However I am worried about starting a new application using ExtGWT as I suspect that is being developed in a separate track from GWT 2.1 and lots of things won't work together so I'd not be able to follow a GWT 2.1 design approach. Please let me know your experiences using 2.1 for non-trivial applications and your thoughts on using ExtGWT. Is there an extension GWT UI widget library(s) that does follow the 2.1 design approach? -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.
