Re: How to update a CellTree after the model changes?
The problem is if the node is open, the open state is preserved (in
the code I showed below) and then it displays "no data". There
appears to be nothing in the code that will make the open icon go
away; isLeaf is never consulted again. I think that's a bug too,
right?

Re: GWT 2.1.0 maven asks for com.google.gwt:gwt-dev:jar:windows:2.1.0??
I run into the same problem.
After changing from 2.0.4 to GWT 2.1.0 I can't execute the tests
anymore.
The tests fail with error:

Re: Fixing Internet Explorer specific memory leaks (circular references, etc)
I'd suggest running Microsoft's memory leak tool and working out which elements, exactly, are leaking in your app and why. Once you know that you can purge them by hand -- this is how I started. I only went into this Widget hack because the list of items I needed to deal with was... really long. :) That said - QA has a different use-case that still leaks in our app as well, so... the story is evolving. I'll update the thread if we find out more in case it's helpful for others. Best of luck! Regards, Paul On Nov 8, 4:31 pm, chrisr wrote: > Thanks jay, got that sorted out.

Re: How to diagnose IE8 javascript error "stack overflow at line: 0"? ends up in Impl.entry0
Hi Brian, I don't have exact figures but what I know is that some structures (Java collections) needs tons of Javascript stack entries to get serialized / deserialized: knowing that , our strategy is to carry single objects or arrays (even of hetegeneous objects) on the wire and reconstruct the more complex structures either on client or server side. regards didier On Nov 8, 8:14 pm, BrianP wrote: > It looks like this is the case - a large/complex object over RPC > causing the problem.

Re: GWT 2.1 MVP Framework Vs MVP4G
I think Mvp4g or GWT 2.1 MVP framework can implement any requirement you have, it's just the way you will have to do it that will be different. Using GWT 2.1 MVP will probably give you more flexbility as it isn't a real framework (it just provides utility classes) but on the other hand, it is more complex and you will have to write more boiler plate code and rewrite functionalities provided by Mvp4g (like code splitting, lazy loading...). As often, the best is to give a try to both and see which one fits you need the best. I would be interested to hear what framework you decide to pick. Any feedback is always great to improve Mvp4g.

HelloMVP suggestion
looking at HellpMVP sample:
@UiHandler("goodbyeLink")
void onClickGoodbye(ClickEvent e) {
presenter.goTo(new GoodbyePlace(name));
}
is it a good idea for the View Implementation to have knowledge about
navigation ?
using goTo and places ?
wouldnt it have been better if Presenter interface in HelloView
interface declared a method like:
void onGoodbyeLinkClicked(name)
and
in HelloActivity
public void onGoodbyeLinkClicked(String name) {
clientFactory.getPlaceController().goTo(new Place(name));
}
this way view is more passive, as it doesnt have knowledge about
navigation and places.
or i am wrong ?

Re: OpenJPA GWT serialization problem.
Hi dparish,
There are three issues here:
1. GWT needs a fully populated object graph to send back to the
client. Lazy fetching will not work across the client / server
boundary, so you must ensure that your code fetches all relations
eagerly (via an annotation or a separate call if needed).
2. JDO and JPA implementations use proxy classes for objects attached
to a persistence manager. Before they can be sent back to the client,
you must detach all objects from the PM.
3. Even then, GWT won't be able to serialize any types for which it
doesn't know the source (like App Engine's Key class). The open source
Gilead project and others like Objectify provide GWT wrappers for
these.
HTH,

"Autobean frozen" problem when reusing editors
Hello, I came across another problem. I have a page setup with various Editors, including a subclass ListEditor (for dealing with a CellTable). They accumulate changes into a RequestContext and it works fine now. I have a "Save Changes" button that fires the request, and now I would like to enable editing again, after the request has been successfully processed. I think I need to create a new RequestContext for that? Here is what I do in the onSuccess-Callback: context = requests.recipeRequest(); this.recipe = context.edit(recipe); context.persist().using(this.recipe).with(driver.getPaths()); driver.edit(this.recipe, context); The last one fails however, because setting a new List causes the ListEditor to detach from the old list, which causes a "flush", which in turn causes a value being written to one of the frozen AutoBeans from the original request. Is that a bug, or am I doing something wrong? Thanks, Tobias java.lang.IllegalStateException: The AutoBean has been frozen at com.google.gwt.editor.client.impl.AbstractAutoBean.checkFrozen(AbstractAutoBean.java: 176) at com.google.code.lunchpad.client.proxy.IngredientProxyAutoBean.access $6(IngredientProxyAutoBean.java:1) at com.google.code.lunchpad.client.proxy.IngredientProxyAutoBean $1.setText(IngredientProxyAutoBean.java:19) at com.google.code.lunchpad.client.recipes.IngredientEditor_RequestFactoryEditorDelegate.flushSubEditors(IngredientEditor_RequestFactoryEditorDelegate.java: 18) at com.google.gwt.editor.client.impl.AbstractEditorDelegate.flush(AbstractEditorDelegate.java: 144) at com.google.gwt.editor.client.impl.AbstractEditorDelegate $Chain.detach(AbstractEditorDelegate.java:75) at com.google.gwt.editor.client.adapters.ListEditorWrapper.detach(ListEditorWrapper.java: 101) at com.google.gwt.editor.client.adapters.ListEditor.setValue(ListEditor.java: 129) at com.google.code.lunchpad.client.recipes.IngredientListEditor.setValue(IngredientListEditor.java: 50) at com.google.gwt.editor.client.adapters.ListEditor.setValue(ListEditor.java: 1) at com.google.gwt.editor.client.impl.AbstractEditorDelegate.initialize(AbstractEditorDelegate.java: 257) at com.google.gwt.requestfactory.client.impl.RequestFactoryEditorDelegate.initialize(RequestFactoryEditorDelegate.java: 83) at com.google.code.lunchpad.client.recipes.edit.EditRecipeView_RequestFactoryEditorDelegate.attachSubEditors(EditRecipeView_RequestFactoryEditorDelegate.java: 15) at com.google.gwt.editor.client.impl.AbstractEditorDelegate.initialize(AbstractEditorDelegate.java: 261) at com.google.gwt.requestfactory.client.impl.RequestFactoryEditorDelegate.initialize(RequestFactoryEditorDelegate.java: 83) at com.google.gwt.requestfactory.client.impl.AbstractRequestFactoryEditorDriver.edit(AbstractRequestFactoryEditorDriver.java: 67) at com.google.code.lunchpad.client.recipes.edit.EditRecipeActivity.edit(EditRecipeActivity.java: 79) at com.google.code.lunchpad.client.recipes.edit.EditRecipeActivity.access $0(EditRecipeActivity.java:75) at com.google.code.lunchpad.client.recipes.edit.EditRecipeActivity $2.onSuccess(EditRecipeActivity.java:110) at com.google.code.lunchpad.client.recipes.edit.EditRecipeActivity $2.onSuccess(EditRecipeActivity.java:1) at com.google.gwt.requestfactory.client.impl.AbstractRequestContext $4.onTransportSuccess(AbstractRequestContext.java:394) at com.google.gwt.requestfactory.client.DefaultRequestTransport $1.onResponseReceived(DefaultRequestTransport.java:155) at com.google.gwt.http.client.Request.fireOnResponseReceived(Request.java: 287) at com.google.gwt.http.client.RequestBuilder $1.onReadyStateChange(RequestBuilder.java:395) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java: 39) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java: 25) at java.lang.reflect.Method.invoke(Method.java:597) at com.google.gwt.dev.shell.MethodAdaptor.invoke(MethodAdaptor.java:103) at com.google.gwt.dev.shell.MethodDispatch.invoke(MethodDispatch.java:71) at com.google.gwt.dev.shell.OophmSessionHandler.invoke(OophmSessionHandler.java: 157) at com.google.gwt.dev.shell.BrowserChannelServer.reactToMessagesWhileWaitingForReturn(BrowserChannelServer.java: 326) at com.google.gwt.dev.shell.BrowserChannelServer.invokeJavascript(BrowserChannelServer.java: 207) at com.google.gwt.dev.shell.ModuleSpaceOOPHM.doInvoke(ModuleSpaceOOPHM.java: 126) at com.google.gwt.dev.shell.ModuleSpace.invokeNative(ModuleSpace.java: 561) at com.google.gwt.dev.shell.ModuleSpace.invokeNativeObject(ModuleSpace.java: 269) at com.google.gwt.dev.shell.JavaScriptHost.invokeNativeObject(JavaScriptHost.java: 91) at com.google.gwt.core.client.impl.Impl.apply(Impl.java) at com.google.gwt.core.client.impl.

gwt-dnd
Hi Everybody I need some drag and drop's in my application. Searching GWT group I found gwt-dnd. I tried some examples and works fine. But I need to be able to drag and drop a widget that will contain some textboxes, buttons, hyperlinks, etc... I am a little confuse. Is possible to make this with gwt-dnd? The way I did following some examples when I click in a textbox, or a button, etc...inside the dragable widget, the textbox does note get the focus. Any advice?

Re: design pattern for common functionality between Activities
I can give you what I did in my application. Maybe that you will prefer this
method :
* When the application loads, the server store a login/logout status of the
user in a json format (just for optimization like this :
http://code.google.com/intl/fr/webtoolkit/articles/dynamic_host_page.html. You
can make an init query to the server to get the status instead of the
previous method, but it is a bit slower)
* My login/logout link is inside its own activity and it has its own
activity manager too.
* I send a new LoginStatusEvent(boolean login) when my status is updated and
it is handled by my Login/Logout activity.
* When user successfully login or logout, I send a new LoginStatusEvent.
* On server side, I use a security framework that check permission on rpc
call. If user is not logged in (session has expired) but want to access to a
"secured method" -> I throw a special remote exception. This exceptions is
handled by a custom AsyncCallback that will redirects the user to a login
page + sends a new LoginStatusEvent(false)
Tell me if this is not clear.
Nicolas.

Re: Accessing GWT app deployed on Jetty fails
What mvn command are you using? In this POM, gwt-maven-plugin is
executing gwt:compile during the prepare-package phase, so you should
run "mvn package" to trigger it.

Re: CompositeCell
It's the latter, though for what we're wanting to do I don't think
AbstractEditableCell is what we want.
What we want to do is bring a name per line in one cell that's
clickable similar to ClickableTextCell for every object of a sub-list
from the model object.
For instance if we had the following two classes:
public class Foo {
private List bars;
private String something;
public List getBars() {
return bars;
}
public String getSomething() {
return something;
}
}
public class Bar {
private String name;
public String getName() {
return name;
}
}
Then we define a cellTable / Column as so:
...
CellTable table = new CellTable();
Column somethingColumn = new Column(new
TextCell()) {
public String getValue(Foo object) {
return object.getSomething();
}
};
table.addColumn(somethingColumn);
// Here's the ideal part + some pseudo code
Column barNames = new Column(new
CompositeCell(HasCell()) {
public String getValue(Foo object) {
for (Bar b: object.getBars()) {
return b.getName();
}
}
};
table.addColumn(barNames);
And finally the output would be something like:
| Something Header | Bar Header |
-
| Cool Stuff | Bar 1 |
| | Bar 2 |
| | Bar 3 |
-
| More stuff | Bar 7 |
...

Controlling the focus in a CellTable

design pattern for common functionality between Activities
Hi GWT gurus,
Learning the new GWT 2.1 framework and I got security up&running on my
GAE application.
Now working with the new Activities/Places.
My applicaiton will have a login/logout link in the top right of the
website/app.
How do I keep this link in sync with the security status of the
current visitor/user.
Will every activity have to check for the status of the of current
user ?
Do I create a super class AbstractMyApplicationActivity that
implements this functionality and then call this in start() for each
child activity ?
like this
public AbstractMyApplicationActivity extends AbstractActivity {
public void updateLoginLogoutLink() {
// set the login/logout link correctly
}
}
public SomeActivity extends AbstractMyApplicationActivity {
public void start(AcceptsOneWidget containerWidget, EventBus
eventBus) {
updateLoginLogoutLink()
... some other activity specific stuff.
}
}
Is there a more elegant pattern for implementing this? Now the
responsibility of making this calling is present in every activity
feels uncomfortable;
thx,
koen

GWT 2.1 RequestFactory and complex properties on my DTO (Entity proxies)
Hi, My entities are persisted via JDO in the Datastore (GAE). I can transfer DTOs to the client by creating EntityProxy objects that match the entity's properties (getters/setters). But how do I transfer the more complex values like com.google.appengine.api.datastore.Email with my DTO object to the client ? these classes com.google.appengine.api.datastore.* are not on the classpath for the client and result in ClassNotFoundExceptions; thx, koen -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

Could anyone please post a pom file to create a war and compile the

Re: Entire Site in GWT?
In my opinion, a full website can be built with GWT (uiBinder is a great helper for this). This is the way that we chose in our company. it is really fantastic to code with gwt and it allows to use so many optimizations for the client side (client bundle, conditional css, ...). Every pages of the website is behind a code split so it does not overload the inital loading of the gwt client side. For Search engine, we implemented this mechanism : http://code.google.com/intl/fr/web/ajaxcrawling/docs/getting-started.html with htmlunit in the backend.,But it is only compatible with google. We are looking for a better solution to handle this problem for all search engine. Nicolas. 2010/11/8 Jambi > Hej Mike, > > GWT Rocks :D! A lot has changed since 2008. And i mean, A LOT.

Re: best way to use chart in GWT
I'm using a combination of http://raphaeljs.com and http://g.raphaeljs.com. It's a SVG based framework, so you'll need a modern browser. There is a GWT port available (http://code.google.com/p/raphaelgwt/), but I don't know whether it's up to date. So I decided to use JSNI.

Re: GWT Modules
I found my problem, my RemoteCommandProxy class which is
used as a wrapper around a HashMap also defined some instance
variables and it appears that GWT had a problem serializing the
class.
I also moved my framework code outside of the main app package
and created a Module xml file for it, that is included as an Inherit
in the main application module. It all works fine except for this
one annoying thing when I go to compile, the module xml file
shows up as an EntryPoint that I need to delete so it will successfully
compile. Is there any Ignore me for an EntryPoint attribute that
needs to be set ???

I have implemented the framework as a child of my main App so it
goes..
app

and I have added framework/client and framework/shared to my source

The App compiles and sort of runs, but I am having two problems..
1) the App compiles fine, but in my main app client classes, the
classes I refer to
from my framework package are reported as unreachable in the editor.

path problems...
2) when I run the app, my click event successfully invokes my client
side handler,
but I never get a response, actually I don't think it sends a request
as my server impl.
The serverImpl servlet is never loaded or goes thru init()
My questions are:
Given the code below does anything look out of line ?
Is this the way to implement a module ?
How do you debug into the RPC call to see what GWT is calling ?
Thank you
John Gentilin
the client side handler is
public void performAction( RemoteCommandProxy cmd )
{
final RemoteCommandProxy _cmd = cmd;
YAVCFService.performAction(_cmd.getName(), _cmd, new
AsyncCallback>() {
public void onFailure(Throwable caught) {
_cmd.executionCompleteFailure(caught);
}
public void onSuccess(Map result) {
_cmd.executionCompleteSuccess(result);
}
});
}
where RemoteCommandProxy extends HashMap and represents the parameters
passed to the server impl.
The idea is I am invoking one servlet interface that takes as
parameters a command name and a map of
named value pairs as parameters. This function returns a Map of named
value pairs in response.
My interfaces are defined as follows
@RemoteServiceRelativePath("yavcf")
public interface YAVCFClient extends RemoteService {
Map performAction(String name, Map
parameters)
throws IllegalArgumentException, InvalidCommandException,
NoSessionException;;
}
public interface YAVCFClientAsync {
void performAction(String name, Map parameters,
AsyncCallback> callback);
}
and my web.xml has the following servlet mapping.

Re: Fixing Internet Explorer specific memory leaks (circular references, etc)
Hi Paul, I'm really interested to see if this works for a project I've been working on, which has a significant memory leak in IE. I haven't worked with deferred bindings in GWT before, and I don't think I'm doing it right, as breakpoints i put in my NoLeaksDOMImpl class never get hit. I'm assuming that you aren't supposed to open up the gwt-user jar and edit the Emulation.gwt.xml file inside, so I added com.google.gwt.emul.Emulation.gwt.xml to my source w/ And I also added com.google.gwt.user.client.impl.NoMemLeaksDOMImpljava to my source..

Re: Gwt 2.1 Activities + Code splitting + Gin
Thanks Thomas. So the way I understand it, the ActivityManager/ActivityMapper are GWT 2.1 equivalent's of GWTP's proxy for the purpose of navigation. It's just that in GWTP you don't need to create or modify a separate class, all is done within your presenter. In my apps, I often have some presenters that need to be awoken when a given message transit on the bus. Say, for example, a ChatBoxPresenter would like to wake up when a NewChatMessageEvent transits on the bus. In GWTP it's simply a matter of annotating a method with @ProxyEvent in the presenter -- ChatBoxPresenter is still lazily instantiated and code split. How would you handle such a case in GWT 2.1 short of instantiating the ChatBoxPresenter at app start? In the GWTP samples we use singleton presenters, which makes it easy to retain state during the app lifetime, a frequent use case. Also, it cuts down on the cost of instantiating and garbage collecting the presenters all the time. Finally, singleton presenters ensure that you don't mistakenly attach two instances of the presenter to the same singleton view. However, nothing prevents you from using non-singleton presenters. GWTP presenters have the equivalent of a resettable event bus, and every handlers are unregistered upon an unbind(). In fact, GWTP offers reusable components separating logic from (non-singleton) views -- which we call PresenterWidget. These are quickly becoming one of the most popular feature of the framework and I don't find their equivalent in GWT. @Nicolas, Re: the need for a proxy interface I believe it is a limitation of GWT generators that they have to be attached to classes/interfaces. If anybody has a better idea I'm a buyer. But isn't it better than manually writing/editing ActivityManagers?

Re: Entire Site in GWT?
Hej Mike, GWT Rocks :D! A lot has changed since 2008. And i mean, A LOT. I know that there is a way now to allow web crawlers to scan your app but I don´t know how, since i´ve never used it so far. By default all of the JS script is loaded at start, but you can use "code split" to split your JS code where you want. I recommend that you check out the GWT talks from Google I/O 2010 and 2009. Most of the talks aren´t that newbie friendly, but you get an idea of the capabilities GWT has. On Nov 8, 5:49 pm, "mike.cann" wrote: > Hi Guys, > > First post on this list.

Creating Editor interfaces needs a little more documentation.

I eventually figured out I needed to use LeafValueEditor.
interface PersonEditor extends Editor{

}
My implementation did return a LeafValueEditor. It just wasn't
readily apparent that my interface method needed to declare the more
specific return type.

Re: gwt 2.1, maven, eclipse 3.5
Hi Frank, Have a look at http://www.google.com/codesearch/p?hl=en#A1edwVHBClQ/samples/expenses/README-MAVEN.txt In a nutshell, make sure you have all the required plugins from the README, copy the Expenses POM to your project, and eliminate unneeded dependencies. If not using App Engine, you should be able to use gwt-maven-plugin version 2.1.0 from Maven Central instead of the 1.3.2.google version in the POM.

Re: widget celltable how clear before re-populate
Using one of the concrete classes AsyncDataProvider or ListDataProvider whose base class is AbstractDataProvider provides a very efficient mechanism for accessing your widget's underlying data source as well as for manipulating the display of the data itself. Once a ListDataProvider is setup you can do similar to below: dataProvider.getList().add(someObjectsList); // add a new SomeObject to the list sortSomeObjectsList(dataProvider.getList()); // call a method to sort the list dataProvider.refresh(); // tell all widgets using the data provider to refresh themselves because the data has changed You can also add & replace lists in a ListDataProvider with: dataProvider.setList(someObjectsList); To set up a ListDataProvider: ListDataProvider dataProvider = new ListDataProvider(); // strongly typed declaration - notice the use of type T in the declaration which is the type specifier for the type of objects in the list dataProvider.setList(someObjectsList); // the list of objects to be provided by the ListDataProvider dataProvider.addDataDisplay(myCellWidget); // the widget the ListDataProvider is providing the data to Jeff On Mon, Nov 8, 2010 at 1:22 PM, John LaBanca wrote: > You can push new data into the widget using CellTable#setRowData() in > conjunction with CellTable#setRowCount().

[Basic] GWT and Google Maps API
Hello Group, I am currently doing some basic research for an upcoming project of mine. Basically I want to simulate a large number of driving cars on Google Maps. The way I imagine it right now is that I want to define a startpoint and an endpoint. Either by GPS Coordinates (xx° yy' zz'') or by an address (f.e. City, Street, Number) for every car. Then I would like Google Maps to calculate the route between the start and endpoint. (Preferably the shortes route) Last but not least a graphic symbol - at least a colored dot - should simulate the driving of a vehicle from the start point to the end point. This should occur in realtime and in addition simulated at lets say 500% of the normal speed. Some kind of a simulation mode. Of course the dot - the car - should move along the streets and not directly from start to end. Is this possible using GWT and the Google Maps API? Can anyone point out best practices, maybe even existing samples? Thanks in Advance for both your time and your help!

Re: CompositeCell
Is it dynamic based on the row value, or dynamic in that it can change? If its the former, you can extend CompositeCell and override the render() method to hide spans that aren't needed. If its the latter, you will probably want to extend AbstractEditableCell and copy the examples in TextInputCell or CheckboxCell.

Re: How to update a CellTree after the model changes?
You should be able to call AbstractDataProvider.updateRowData() with just
the one updated row value, which will only cause that row to refresh.
However, there is a bug in CellTree (will be fixed in GWT 2.1.1) which
always causes it to update the 0th item.
Is there any way of making a node go from having children to having
> no children again in a CellTree?
You can set the row count in the child DataProvider to 0. The node won't be
a leaf node, but it won't have any children. If you really want it to be a
leaf node, you have to refresh the node using the same method above.
Thanks,

Re: widget celltable how clear before re-populate
You can push new data into the widget using CellTable#setRowData() in conjunction with CellTable#setRowCount(). If you want to clear the data first, do the following: myCellTable.setRowCount(0); // Clears all data myCellTable.setRowCount(20, true); // Set the size of the new data myCellTable.setRowData(0, myData); // Set the new data In GWT 2.1.1, there is a new method CellTable#setRowData(List) that clears all existing data and replaces it with the specified list.

Dynamic Gwt Module embed leads to blank page (onInjectionDone)
Hi, im trying to dynamically embed a gwt module into an jquery
application. In this application i have pages which contain gwt
modules. In such an page, i simply add the gwt container div, the
script (nocache.js) and the css tag to the html body code. The problem
is, when i do that this way, the page gets loaded and disappears after
the gwt module was loaded.
Than i just get a blank page, with this script inside:
andorialowlevelanimations.onInjectionDone('andorialowlevelanimations')
When i add the script tag and the div id to the main startpage, inside
the head, (where jquery and other scripts get loaded) everything works
fine. Can anybody tell me why this happens?
Greets and thanks, ah and sorry for my english :)

Doubt about Places and Activities
Hi, i would like to implement the new GWT 2.1 MVP Framework, but i have a few doubts. In my gui i have a TabPanel and inside each tab i have few links that display another view in the tab panel container.

"Add User" and "List Users" actions are Activities don't?

If you use IsSerializable (and no type name elision), and don't have any actual API changes, you'll be okay, you user shouldn't notice. Otherwise you'll have to catch IncompatibleRemoteServiceException and ask your user to reload the app. I was mulling over this scenario awhile ago and wrote a blog post about it: http://www.draconianoverlord.com/2010/07/07/gwt-seamless-upgrades.html - Stephen -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

How to update a CellTree after the model changes?
I'm having a hard time understanding how I can update things like the
label of a node in the cell tree when I know its value has changed in
the model being viewed. Right now I have a rather brute force
approach: I update the entire set of children for the parent by
calling AbstractDataProvider.updateRowData. At least it works, but
it's like a sledge hammer. I have yet to figure out how to update
just the one child; maybe I just ran into bugs in the older pre-
release versions and have to try again. Also, I have to do similar
things if children are added, i.e., if a node y has a child z added,
and originally y had no children, I have to tell the parent node x of
y to update all its children so that it updates the expansion icon to
reflect that y is no longer a leaf. But, now matter how hard I wrack
my brain, I cannot find a way to make a node go from having children
back to being a leaf again. The only way I can get this to work is to
hack the code:
// Create a set of currently open nodes.
Set openNodes = new HashSet();
int childCount = nodeView.getChildCount();
int end = start + values.size();
for (int i = start; i < end && i < childCount; i++) {
CellTreeNodeView child = nodeView.getChildNode(i);
// Ignore child nodes that are closed.
if (child.isOpen() && !child.isLeaf()) { ///
<-- add the test to not save the open state if it's a leaf.
openNodes.add(child.getValueKey());
}
}
Is there any way of making a node go from having children to having no
children again in a CellTree?

Session Managment for more than one GWT-Project
Hi there, I'm writing an GWT-App containing several sub-projects. To keep the App lightweight and easy I created different projects for each subproject linking to each other. I deployed the projects on my Tomcat and it works fine, BUT: As every subprojects has its own server-classes and therefore creates its own session, i cannot recognize an user who logged in on a different page. so my question is: is there any way to tell the apps to share the session managment? or do i have to restructure my whole project again? thanks a lot! tom -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

best way to use chart in GWT
Hi I'm having problem to decide what is the base way to implement chart in gwt. i taught about gwt library (i.e. gchart of gflot) - but they are insufficient by look, interaction and components. Also looked at gwt visualization but it requires open link to the web, (i need it in intranet). And also look at some javascript library - but then i need to write wrappers and take care of the cross browser issue. P.s. i cannot use flash component as well. currently it seems that wrapping the javascript library is the best solution, but i'll be happy to hear other suggestions, or experiences before diving in.

GWT Modules
I am trying to create a framework for a GWT app I am writing. This
framework will want to implement and handle all the Service,
ServiceAsync and ServiceImpl classes. The main application classes
will extend the framework view class, and the application serverImpl
class will extend the frameworkImpl class.
I have implemented the framework as a child of my main App so it
goes..
app
client
server
shared
framework
client
server
shared
and I have added framework/client and framework/shared to my source
definition..
The App compiles and sort of runs, but I am having two problems..
1) the App compiles fine, but in my main app client classes, the
classes I refer to
from my framework package are reported as unreachable in the editor.
Source
path problems...
2) when I run the app, my click event successfully invokes my client
side handler,
but I never get a response, actually I don't think it sends a request
as my server impl.
The serverImpl servlet is never loaded or goes thru init()
My questions are:
Given the code below does anything look out of line ?
Is this the way to implement a module ?
How do you debug into the RPC call to see what GWT is calling ?
Thank you
John Gentilin
the client side handler is
public void performAction( RemoteCommandProxy cmd )
{
final RemoteCommandProxy _cmd = cmd;
YAVCFService.performAction(_cmd.getName(), _cmd, new
AsyncCallback>() {
public void onFailure(Throwable caught) {
_cmd.executionCompleteFailure(caught);
}
public void onSuccess(Map result) {
_cmd.executionCompleteSuccess(result);
}
});
}
where RemoteCommandProxy extends HashMap and represents the parameters
passed to the server impl.
The idea is I am invoking one servlet interface that takes as
parameters a command name and a map of
named value pairs as parameters. This function returns a Map of named
value pairs in response.
My interfaces are defined as follows
@RemoteServiceRelativePath("yavcf")
public interface YAVCFClient extends RemoteService {
Map performAction(String name, Map
parameters)
throws IllegalArgumentException, InvalidCommandException,
NoSessionException;;
}
public interface YAVCFClientAsync {
void performAction(String name, Map parameters,
AsyncCallback> callback);
}
and my web.xml has the following servlet mapping.
yavcfServlet
com.ecs.toodlejirado.server.ToodleJiraDoServer
yavcfServlet
/toodlejirado/yavcf

Re: GWT designer and problem with smartGWT
The "Configure for using SmartGWT" command is provided as a convenience. All it does is follow the same instructions for setting up SmartGWT that are provided on the SmartGWT web site. GWT Designer does not add or remove any requirements for using SmartGWT. That command will only appear if the project is not already using SmartGWT. That info is usually recorded to your module xml file. If you have general problems using SmartGWT, I would recommend asking them in the SmartGWT forum.

Re: GWT Timer with IE
Fortunately, the new version of GWT (2.1.0) has dealt with this
problem.
It seems to be fine for almost browser :)

Re: GWT 2.1.0 maven asks for com.google.gwt:gwt-dev:jar:windows:2.1.0??
worst decision ever to get on the maven/spring-roo boat. after 25 mins of waiting while maven is downloading after issuing "perform eclipse" for a basic spring-roo, maven stumbles with an error because JAVA_HOME is not properly set. after fixing that, "perform eclipse" works but the resulting project is in conflict with the Google Plugin and running the apps fails due to missing dependencies that maven apparently overlooked and maven is supposed to make life easier, well, not mine for sure. -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

Do anyone know of any good guide for creating a gwt 2.1 project in maven, and fully integrating it with eclipse?

Re: can't import into eclipse using mojo.codehaus.org gwt-maven-plugin 2.1.0
Actually, it was my mistake (I'm a maven rookie). I was accidentally using version 1.2 of the plugin. This version doesn't seem to automatically generate all of the misc eclipse files that version 2.1.0 creates. However, now I have another problem... Now when I import the resulting project into eclipse, I get lots of compile errors, plus the following error in my maven console: Error: Could not find the resource '[omit package]Messages.properties matching '[omit package].Messages' did you remember to add it to your classpath? A few of the compile errors are appended below. This is probably another newbie mistake. Any help is appreciated.

Re: Gwt 2.1 Activities + Code splitting + Gin

But if you > really want to write proxys yourself, GWTP's allows it. > Yes, I agree that I was a bit unfair with GWTP. In my opinion, it would be a geater tool (for me) if the code in front of generators were more concise (just annotation, no empty interfaces to add), and maybe more "optional". bindPresenter() needs view, proxyplace, presenter. But if I prefer to not use ProxyPlace as you suggest, I can't. > Out of curiosity, which version of GWTP did you try? > 0.4.

I'm not sure but I think you should (as in "it's intended that you") use a FieldUpdater (in CellTable) or ValueUpdated (in CellList) to handle the "commit" of the value and do your RPC. -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

Re: Gwt 2.1 Activities + Code splitting + Gin

I think the overall idea of activities is that they are short-lived instances, so they're effectively "lazily created" (actually, a new instance is created each time one is needed) and they don't need to be "awoken" because if they're not currently in use they're already "dead" and garbage collected. The ActivityManager (actually its associated ActivityMapper) will decide whether a particular activity is needed (and then instantiate it, possibly going through a GWT.runAsync for code splitting); the activity will listen to events its interested in *during its lifetime* (e.g. whether some object has changed or has been added or deleted, so it can update its view); but when it's done (stopped or cancelled), it's simply thrown away (the event bus passed to the start() method is a ResettableEventBus so all handlers have been automatically unregistered for you, which as a side effect allows the activity to be garbage collected). This is the (AIUI) intended use, but nothing forces you to write such short-lived instances: you can very well use singletons, but then you'll have the additional task of maintaining state between "runs" (start/stop or start/cancel), in which case your activity can listen to events from the event bus after being stopped/cancelled (just use the "real" event bus instead of the ResettableEventBus passed to the start() method); but it won't "ask to be revealed": navigation is handled at another layer, triggered on the PlaceController and handled by ActivityManagers. -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

Re: SelectionModel and ListDataProvider are out of synch
On a related subject why is there no 'reset'/'clear' method on the selection model. I find myself in the situation where I would need to reset the selection model (affecting a new one is not an option as I have handlers registered on the former).
