ORM or JDBC?
Hi everybody, I would like your opinion regarding the use of ORM in web applications built with GWT.

Hi,
I have the following problem. I have a celltable with 2 columns. These
columns contain Filenames and their size.
Due to the fact that i have many files that i want to display I want
to use Paging. In my last project i used gwt 2.1 and the paging worked
there. The simplePager in GWT 2.2 does not work in my new project but
its still the same code that should work.
Can anyone show me where it goes wrong? Thanks.
Here´s my code reduced to the SimplePager things:
public class CellTableTestClass {
private VerticalPanel applicationPanel = new VerticalPanel();
private CellTableLogData cellTable = new CellTableLogData();
private SingleSelectionModelLogData selectionModel = new
SingleSelectionModelLogData();
public VerticalPanel createContent() {
LogFileServiceAsync initData = (LogFileServiceAsync)
GWT.create(LogFileService.class);
initData.getLogs(new AsyncCallbackList LogData() {
public void onFailure(Throwable caught) {
Window.alert(caught.getLocalizedMessage());
}
public void onSuccess(ListLogData result) {
cellTable.setRowData(result);
}
});
cellTable.setSelectionModel(selectionModel);
{
cellTable.addColumn(new TextColumnLogData() {
@Override
public String getValue(LogData object) {
return object.getLogName();
}
}, Log Name);
cellTable.addColumn(new TextColumnLogData() {
@Override
public String getValue(LogData object) {
return object.getSize();
}
}, Size);
}
// create a pager, giving it a handle to the CellTable
SimplePager.Resources pagerResources =
GWT.create(SimplePager.Resources.class);
SimplePager pager = new SimplePager(TextLocation.CENTER,
pagerResources, false, 0, true);
pager.setDisplay(cellTable);
pager.setPageSize(10);
// add the Pager to the dialog
applicationPanel.add(pager);
applicationPanel.add(new HTML(hr /));
applicationPanel.add(cellTable);
return applicationPanel;
}

Re: ORM or JDBC?
note, that you can mix JPA and JDBC - there's no need to decide for only one of them. I try to use JPA 2.0 as much as possible with Hibernate as persistence provider. For special cases , I fall back to native SQL commands or even plain JDBC. what I like with JPA/Hibernate: * it's easier to use objects than mess with the basic data types * you get a lot of type checking out of the box * JPA 2.0 has type-safe queries * Hibernate can generate the DB-create scripts for you (and also update scripts to a certain degree) another note: you cannot use Entities directly on the GWT client side, but there are different ways to handle this: e.g. DTOs or GWT-Request Factory, or tools like GILEAD, etc.. see: * http://code.google.com/webtoolkit/articles/using_gwt_with_hibernate.html * http://code.google.com/webtoolkit/doc/latest/DevGuideRequestFactory.html On Mar 24, 10:13 am, Subhrajyoti Moitra subhrajyo...@gmail.com wrote: JDBC rocks. so does hand written finely tuned sql statements. presence of a DBA helps a lot. my 2 cents.

RPC Serializable = invalid objects graph?
Hi,
I have the following setup:
import java.io.Serializable;
class A implements Serializable {
SetB bs;
SetC cs;
}
class B implements Serializable {
SetC cs;
}
class C implements Serializable {
SetB bs;
}
I send an instance of A from client to server using GWT RPC. After
deserialization the objects graph is no longer intact. Multiple
instances of what was earlier one instance have been created and
referenced to respectively.
Example:
Before serialization: instance x of A.bs == instance x of C.bs.
After deserialization: instance x of A.bs != instance x of C.bs.
As I understand it, this should not happen as the serialization of all
the above instances is written to the same stream.
I know that GWT RPC only implements parts of java.io.Serializable.
Does this explain this behavior or does anyone have an idea?
Thanks,
Carl

Re: MVP placeController History back activity mayStop
Maybe setting a static field to a specific value which could be read in the mayStop() method. If it's set to the parameter, do not ask the questions.

Re: RPC Serializable = invalid objects graph?
GWT-RPC serialize objets graphs by POST and isn't do exact JVM
serialization. You must implement equals and hashcode and then if you
compare with equals then:
Before serialization: instance x of A.bs equals instance x of C.bs.
After deserialization: instance x of A.bs equals instance x of C.bs.

ProxyAutoBean server-side cache
Hi, it appears that for every EntityProxy instance that a client requests via RequestFactory, a ProxyAutoBean object is created on the server. Is this correct? If so, what is the lifecycle of the ProxyAutoBean, at what point does it get deleted? I can see (in jvisualvm) that it lives in a WeakMapping, so maybe it is intended to be removed when the GC needs the memory it occupies. However, a few initial tests seem to show that the ProxyAutoBeans survive low memory conditions and keep accumulating.

Dialog box that doesnt grey out background and allows me interact with background

My users will need to be able to copy and paste text from the background into the dialogue box... and things like that. I see that there is only one type of dialogue box with GWT. Its great that its dragable, however it greys out the background :( Also I was hoping for a dialog that is collabsible. Our team has to use GWT and cant use any other toolkit (ajax/jquery). Im not even sure we can use third parties. Id love to hear someones opinion on how I could acheive what I want with the core GWT toolkit. If not a suggestion for a third party GWT extnesion might do.

Re: Doc reference perhaps?
All you need to do is to create a jar file with: - your .class files as you would for a regular java program - your .java source files -- these are required so your users can use GWT to translate to javascript - whatever gwt.xml files are appropriate (at least one) Then, a user of your library would put your jar file on their classpath at compile time, and add an inherits ... line into their gwt.xml to inherit your module(s).

Re: Is gwt serialization backward compatible ?
I would not recommend either use GWT serialization or JVM serialization to store in a file, it isn't the main purpose. First, don't trust that GWT never change Serialization method in the future. Second, JVM serialization use serialversionuid to check if the .class is compatible and the version of JVM (a class serializate with 1.5 is not compatible with 1.6). I recomend use XML o JSON to store class. There are a lots of frameworks around to do this job. Juan 2011/3/24 Kroc vincent.legen...@gmail.com any ideas or advises ?

Re: RPC Serializable = invalid objects graph?
GWT RPC does normally preserve object graphs properly, so an instance is only
ever written out once. If the same object is referenced multiple times in an
object graph, the first time it writes out the full object, and subsequent
times it writes a reference back to the thing it wrote out before.
You need to be careful with circular references held in sets/maps, but it
doesn't sound like this is your issue:

deserialization the objects graph is no longer intact. Multiple
instances of what was earlier one instance have been created and
referenced to respectively.
Example:
Before serialization: instance x of A.bs == instance x of C.bs.
After deserialization: instance x of A.bs != instance x of C.bs.
As I understand it, this should not happen as the serialization of all
the above instances is written to the same stream.
I know that GWT RPC only implements parts of java.io.Serializable.
Does this explain this behavior or does anyone have an idea?
Thanks,
Carl

complex example GWT Activity and Place
Hello,
Is there any complex example on how to nest Views when using the GWT
Activity and Place. For example, I have a MainWidget which acts as a parent
View for all other Views that have got a Place. My question is, how can I
place other Views in the MainWidget? If this is not possible, does this mean
every View can outrightly be its own widget? My reason for wanting the
MainWidget to house other Views is because I want the MainWidget to control
the entire layout of the application, so that other Views (URL based
widgets) can just go ahead and do their own specific things.
From the HelloMVP, there's this line:
private Place defaultPlace = new HelloPlace(World!);
private SimplePanel appWidget = new SimplePanel();
// Start ActivityManager for the main widget with our ActivityMapper
ActivityMapper activityMapper = new AppActivityMapper(clientFactory);
ActivityManager activityManager = new ActivityManager(activityMapper,
eventBus);
activityManager.setDisplay(appWidget);
Taking this one level up, does this mean that the GoodbyeView and HelloView
Views are attached to appWidget and are both visible at Place World? What
about if I have widgets and not Views, can these widgets be attached to for
example appWidget? Also, assuming I have another Place at Heaven, with its
own Views, how can I discard the widgets already showing in appWidget? Is
this something the ActivityManager takes care of automatically?
One other question, I have an Hyperlink that's got a #profile token. From my
understanding of Place, if I click on the Hyperlink which appends #profile
to the URL, the ActivityManager should call the corresponding Place which is
set at profile. Right now this is not working for me. I have this:
registerHandler(display.showAgentProfileView().addClickHandler(new
ClickHandler() {
@Override
public void onClick(ClickEvent event) {
//eventBus.fireEvent(new MainSignupEvent());
getAgentProfileActivity();
}
public void getAgentProfileActivity() {
Window.alert(getAgentProfileActivity Request is called);
History.newItem(profile);
History.addValueChangeHandler(this);
History.fireCurrentHistoryState();
// Start ActivityManager for the main widget with our
ActivityMapper
ActivityMapper activityMapper = new AppActivityMapper(mainp);
ActivityManager activityManager = new
ActivityManager(activityMapper, geventBus);
activityManager.setDisplay((AcceptsOneWidget)mainp.getDisplay().getAgentProfileView().asWidget());
Place agentprofile = new AgentProfilePlace(profile);
PlaceController agentprofilePlaceController =
mainp.getPlaceController();
AgentProfilePlaceHistoryMapper agentprofilehistoryMapper=
GWT.create(AgentProfilePlaceHistoryMapper.class);
PlaceHistoryHandler historyHandler = new
PlaceHistoryHandler(agentprofilehistoryMapper);
historyHandler.register(placecontroller, geventBus,
agentprofile);
}
I will also like to know, can the ActivityManager be called anywhere else
other than in onModuleLoad. My reason is because, since the issue of
decoupling is a big factor in MVP, I tend to have my events handled in the
Presenter implementing class. Please correct me if I'm wrong with the
interpretation.

How to get mouse position from NativeEvent
Hello, everybody!
I'm implementing custom cell, extending AbstractCell. One problem I
have is related to event handling.
My cell has image, and I need to know the mouse position related to
this image.
In method
public void onBrowserEvent(Context context, Element parent, Integer
value,
NativeEvent event, ValueUpdaterInteger valueUpdater) {
}
I have NativeEvent which has methods
getClientX()/getClientY() which is position in the browser window's
client area.
How to convert them to my image coordinate?
Thank you ,

in onModuleLoad? Also, the concept of Place itself, as described above.

@AlternateMessage and null values
Hey All,
I'm trying to use the new @AlternateMessage annotation in my
message interface to control messages when some values are null and
some are not. The javadoc for the AlternateMessage says it accepts
Strings but it doesn't seem to handle a null value whether I try to
mark it with none or null. Any suggestions on how I can get this to
work?

class=''label''Alt ID:/span {1}, span class=''label''CIS #:/
span {2}, span class=''label''Name:/span {3})
@AlternateMessage({
other|none|none, span class=''label''User ID:/span {0},

GWT For Usability Testing. Do I need to know Java? Can I use a HTML template?

Problem with Gilead Integration in GWT, Spring and JPA
hey, I'm a newbie with these frameworks. Firstly i want to write a small web app with gwt for the frontend, spring for backend and jpa for the persistence operations. I use Hibernate as JPA implementation. I started with a simple construction (2 simply entities, 2 DAO,1 remote service). I have no problems with this example. After i had extended the entities with lists, i got some problems with the lazy loading and serialization. Therefore i searched for solution and found the Gilead Framework. Now i have following problem: org.hibernate.LazyInitializationException: failed to lazily initialize a collection of role: list attribute of my class, no session or session was closed at org.hibernate.collection.AbstractPersistentCollection.throwLazyInitializationException(AbstractPersistentCollection.java: 383) at org.hibernate.collection.AbstractPersistentCollection.throwLazyInitializationExceptionIfNotConnected(AbstractPersistentCollection.java: 375) I don't understand the problem, because i marked the service method with @Transactional(propagation=Propagation.NESTED, readOnly=true).

Re: MVP pattern for Tabbed UI (Each Tab = Unique Module e.g. Orders)
I concur with Y2i regarding the use of a top TabBar, I'm using a similar approach. Other things you may want to add: - Loose coupling between TabBar and content presenters (they are not injected in one another). The TabBar sends an event on the bus to discover and collect all the content presenters it should handle. The TabBar sends an event when a tab is clicked to display the corresponding presenter. - History support You may want each tab to corresponds to a different history token. This one is trickier to do as it requires two way communication between the content presenters and the TabBar presenter: when a presenter is displayed, it needs to tell the TabBar which tab to highlight. - Nested tabs It gets slightly trickier if you want to support TabBars within TabBars, à-la Google Code You can have a look at GWTP for inspiration on how to do all of the above.

A DialogBox can be *modal* or *modeless*: http://google-web-toolkit.googlecode.com/svn/javadoc/latest/com/google/gwt/user/client/ui/DialogBox.html#DialogBox(boolean, boolean) In the Showcase, it's created using the default (no-arg) constructor, which makes it a modal dialog box that does *not* auto-hide. Moreover, it's setup with *glass enabledhttp://google-web-toolkit.googlecode.com/svn/javadoc/latest/com/google/gwt/user/client/ui/PopupPanel.html#isGlassEnabled() *, with a style that makes it gray-out the rest of the page; but again that's just one option. There's no collapsible dialog box in GWT, but you might be able to do it by adding a clickhandler to the caption and playing with the dialog content in response to click events. -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: complex example GWT Activity and Place
Hi Odeyemi,
See slides 32-47 here:
http://www.slideshare.net/turbomanage/whats-new-in-gwt-22
Also, this sample project has two ActivityManagers showing how the same
Place can be mapped in both (albeit one is null).

Hello,
Is there any complex example on how to nest Views when using the GWT
Activity and Place. For example, I have a MainWidget which acts as a parent
View for all other Views that have got a Place. My question is, how can I
place other Views in the MainWidget? If this is not possible, does this mean
every View can outrightly be its own widget? My reason for wanting the
MainWidget to house other Views is because I want the MainWidget to control
the entire layout of the application, so that other Views (URL based
widgets) can just go ahead and do their own specific things.
From the HelloMVP, there's this line:
private Place defaultPlace = new HelloPlace(World!);
private SimplePanel appWidget = new SimplePanel();
// Start ActivityManager for the main widget with our ActivityMapper
ActivityMapper activityMapper = new AppActivityMapper(clientFactory);
ActivityManager activityManager = new ActivityManager(activityMapper,
eventBus);
activityManager.setDisplay(appWidget);
Taking this one level up, does this mean that the GoodbyeView and HelloView
Views are attached to appWidget and are both visible at Place World?
Each ActivityManager is responsible for its own area of the screen. Each
ActivityManager has its own ActivityMapper, and each can map the same Place
to a different Activity.
What about if I have widgets and not Views, can these widgets be attached
to for example appWidget? Also, assuming I have another Place at Heaven,
with its own Views, how can I discard the widgets already showing in
appWidget? Is this something the ActivityManager takes care of
automatically?
When you change Place, the new Activity(ies) start() method(s) should call
panel.setWidget() to replace the current contents of the panel.
ActivityManager does not discard widgets automatically unless the new
Activity is null.
One other question, I have an Hyperlink that's got a #profile token. From
my understanding of Place, if I click on the Hyperlink which appends
#profile to the URL, the ActivityManager should call the corresponding Place
which is set at profile. Right now this is not working for me. I have
this:
registerHandler(display.showAgentProfileView().addClickHandler(new
ClickHandler() {
@Override
public void onClick(ClickEvent event) {
//eventBus.fireEvent(new MainSignupEvent());
getAgentProfileActivity();
}
public void getAgentProfileActivity() {
Window.alert(getAgentProfileActivity Request is called);
History.newItem(profile);
History.addValueChangeHandler(this);
History.fireCurrentHistoryState();
// Start ActivityManager for the main widget with our
ActivityMapper
ActivityMapper activityMapper = new AppActivityMapper(mainp);
ActivityManager activityManager = new
ActivityManager(activityMapper, geventBus);
activityManager.setDisplay((AcceptsOneWidget)mainp.getDisplay().getAgentProfileView().asWidget());
Place agentprofile = new AgentProfilePlace(profile);
PlaceController agentprofilePlaceController =
mainp.getPlaceController();
AgentProfilePlaceHistoryMapper agentprofilehistoryMapper=
GWT.create(AgentProfilePlaceHistoryMapper.class);
PlaceHistoryHandler historyHandler = new
PlaceHistoryHandler(agentprofilehistoryMapper);
historyHandler.register(placecontroller, geventBus,
agentprofile);
}
When using Activities Places, you don't need to call any methods on
History directly. Instead use historyHandler.handleCurrentHistory(). The
rest of the code in your getAgentProfileActivity() method should be run
during application setup (called from onModuleLoad, not a ClickHandler as
shown here). Finally, the ClickHandler should call placeController.goTo(new
AgentProfilePlace());
I will also like to know, can the ActivityManager be called anywhere else
other than in onModuleLoad. My reason is because, since the issue of
decoupling is a big factor in MVP, I tend to have my events handled in the
Presenter implementing class. Please correct me if I'm wrong with the
interpretation.

Re: Creating a reusable DialogBox with UiBinder?
Your class using custom widget should be able to make calls related to
styling as you do for any other widget. And add styling to it as you
would do for widgets. Do you mean you want to have only one uniform
style accross the application? If yes then you can add styling inside
the uibinder or in factory m,ethod you have in your custom widget.
Hope that helps.

Hi,
I'm trying to create a number of reusable dialog boxes using

}
... but I want to define the Dialog in its Own MyDialogBox.ui.xml
MyDialogBox.java files and the above code could be called in a number
of places.
So far I have:

public MyDialogBox()
{
uiBinder.createAndBindUi(this);
}
@UiFactory
DialogBox thatsJustMe()
{
return this;
}
}
This seems... wrong? Is there a better way?? I can't control the
dialog size with setWidth/Height.. it screws up royally.
Is there a tutorial?
And I DO NOT want to embed the dialog box in another UiBinder file as
I see all over the place.. its not reusable. (as
in:http://h2g2java.blessedgeek.com/2010/02/tutorial-gwt-rpc-stub-modifie...)

Re: Creating a reusable DialogBox with UiBinder?
Hrm, perhaps I'm not understanding you or I may not be explaining the issue right... I want to create a UiBinder that represents a DialogBox.. this DialogBox will be passed a bean that describes the data it should use to build itself (perhaps it is an editor, or a viewer). The point of creating it as its own entity is that I can then call it from anywhere, as opposed to it being embedded into another UiBinder, and me having to replicate the UiBinder DialogBox there as well. I'm basically making a custom DialogBox widget. Am I making any sense? I just can't find a good example of anyone doing this. Everyone seems to embed the g:DialogBox .../ ui in other UiBinder components. -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: Problem with Gilead Integration in GWT, Spring and JPA
Your collection is mapped as lazy, which means hibernate will load data on demand rather than up-front. However, you then try and access the collection outside a hibernate session, so it cannot do the load. You should either load what you need inside the hibernate session, or make your collection be non-lazy. On 24/03/11 14:50, marky8264 wrote: hey, I'm a newbie with these frameworks.

Re: Creating a reusable DialogBox with UiBinder?
I guess it *seems* wrong because I don't fully understand it, and that there is no official example. GWT is pretty light on the documentation, especially in regards to the UiBinder. Some components (DatePicker/DateBox) don't even have UiBinder Docs. I had to do a google search to confirm that yes, importing com.google.gwt.user.datepicker.clientas another xmlns is required (why isn't it in the UI package???). I also have minor issues in that I cannot set the width and height via the g:DialogBox .../ tag. It either does not work or renders out of sorts... ?? Perhaps I did something wrong elsewhere. Calling .center() also seems to not quite work. (it is certainly NOT centred). I just want to make sure I'm doing it right before I get too far down the development path. *Off Topic: The GWT is fantastic, don't get me wrong. I hardily recommend it over Ext.js, Dojo, etc. However there isn't a clear indication of any right way. There is The MVP, MVC, then RPC or RequestFactory... UiBinder or Java abased UI definition... GAE (which we can't use) or 2-3 year old examples of JPA/Hibernate... Spring/Spring Roo/GINGUICE. And just about every tutorial has a mixture of these frameworks. There are half a dozen different custom frameworks that implement the EventBus and some form of MVP/Action/Presentation/etc... And nowhere is there a central repository of knowledge where the merits of all the different options are debated, where the winners are presented as a cohesive solution. As a newcomer to GWT, I am left feeling lost half the time.

interface TabbedDialogViewUiBinder extends UiBinderWidget,
TabbedDialogView {

The UiBinder file should just contain say a HTMLPanel or say a FlowPanel
containing the dialog contents.

Need some help on Editors
Hi everyone
I'm having trouble understanding Editors introduced in GWT 2.1. It
sounds like a nice feature to reduce boilerplate code. The Dev Guide
is very very useful, but I couldn't get all the answers _
==
my first question is about validation and error reporting.
take the Dev Guide example,
public class PersonEditor extends Dialog implements EditorPerson {
Label nameEditor;
...
}
I wish to detect bad names, create a visual feedback upon error, and
bubble this information up so the caller knows not to proceed further.
I see there is recordError in EditorDelegate. Is it the right method
to tackle this? Can I get an example please? I have a lot fields to
edit. I hope I don't have to create bunch delegates. The less code the
better =)
==
second question is about Q: How can I edit objects with a large
number of properties? from the FAQ section
It has the following example
class BagOfStateBiographicalEditor implements EditorBagOfState {
AddressEditor address;
Label name;
}
class BagOfStateUserPreferencesEditor implements EditorBagOfState {
CheckBox likesCats;
CheckBox likesDogs;
}
How do I chain up the two editors? Should I use a CompositeEditor? or
a list of drivers?
=
many thanks

CellTree Resources too general?
The CellTree's Resources seem a bit too prohibitive for what I'm trying to do. My tree is a table of contents for a set of topics for online documentation. We have a scope setting where a user can choose to filter out any topics that don't pertain to them. In the TOC, these topics appear gray. You can see the current version here: http://dcx.sybase.com/index.html#1200en/sqlanywhere_en12/help_top_index.htm I'm trying to change the tree implementation to a CellTree, but I'm having difficulties styling it to look the same. First off, I'd like to have an image specific for leaf nodes. I can probably get around this one inside the cell rendering. My model is pretty robust, so information about whether child nodes exist (even if they haven't been loaded) is available. The more difficult issue I'm having is figuring out what to do about styling branches of the tree with different images. Basically, I want to be able to change the open/closed images for only specific branches of the tree. The Resources class doesn't seem extensible in this way, however. Any suggestions on how I should go about this would be greatly appreciated!

Yes, have a look at the DynatableRf sample and its ZipPlusFourBox widget.

from GWT.

The delegate is provided to you by the editor framework, you have to

What do you mean by chaining them? à la wizard? then either you use them
as they do in the example and just adjust their visibility (use a DeckPanel
or TabPanel/TabLayoutPanel?), or you use 2 drivers. I think you don't
generally need 2 drivers; and you don't need a CompositeEditor here,
CompositeEditor is for editing an object that's composed of zero or more
other objects (zero or one = OptionalEditor, a List of objects =
ListEditor)

Re: When is an object passed over RPC safe to modify?
Javascript is single threaded, so you can just mark them as clean just before you send them. IOW. It won't be possible for them to be updated between when they are marked as clean, and when the call to save starts. If the save fails, just mark them back to being modified. Note: During the save process on the server, they can be modified. On Mar 24, 4:19 am, Martin Larsson martin.liste.lars...@gmail.com wrote: We're experimenting with background saving in our GWT-app. IOW. we mark objects as 'modified', and then at regular intervals, find all modified objects and pass them to the database for storage. The question is when is it safe to mark the object as 'clean'. The on- success-handler of the save()-method is too late, obviously. That can happen any time later and the user might have modified the object(s) again. As the status also can be 'new' or 'deleted', I need to pass the status to the server so it knows what to do. IOW. I can't mark the object clean too early. What I'd like is to mark them 'clean' when they're safely serialized, and have the on-failure-handler set them back to 'modified' if the save() failed. So ... is there any point in the code where I can be certain that the objects are serialized and on their way to the server so I can start modifying them in the client without interfering? Figure 4 here:http://eclipse.dzone.com/news/making-gwt-remote-procedure-ca indicates that the objects are safe once the method in *Async returns. Is that safe?

Re: image.getWidth() does not work in GWT. Any workarounds?
Make sure you add the load handler before attached to the root panel. If
the image is cached, IE will fire the load event synchronously, before your
handler is attached.

[gwt-contrib] Re: Move com.google.gwt.requestfactory to com.google.requestfactory (issue1383808)
I spent a few days attempting this -- it's not so simple. For example: 1) Enums can't extend Enums. Several public types contain nested Enums. 2) If a type oldA extends newA, and a method in it returns an instance of oldA, you cant simply delegate to the implementation in newA since that will return a newA, which is not an instanceof oldA. So you need to write wrappers for everything. 3) It's unclear to me how inheritance works on annotations 4) Generators will have to be modified to work off the different annotation types I think there were other problems as well that I can't recall at the moment. My belief is that continuing with this approach would have polluted the new code base with special cases to handle parallel enums and annotations. I spoke to Ray about it and he agreed to the plan of leaving a snapshot in the old location and trying to remove it in the next release.

Hi All, This would be real good feature which is pending from long time. We should incorporate this in GWT 2.3 release. It should go in Milestone trunk.

[gwt-contrib] Memory leak in ResettableEventBus
Not sure how this contributing thing works. I was assuming that things get pushed here automatically if I created an issue at the review site. I uploaded some code to deal with memory leak in ResettableEventBus. Mainly with nested ResettableEventBus and passing ResettableEventBus into ActivityManager. http://code.google.com/p/google-web-toolkit/issues/detail?id=5700 http://gwt-code-reviews.appspot.com/1388804/ Really simple fix and would really love to get this included in the next release as I keep having to patch/include my own ResettableEventBus in my code. As I was working on this code I noticed that CountingEventBus has the same bug but I'm guessing that only gets used in tests? Also I wasn't sure how to write a test that check the internal state. Mainly to test for the memory leak the current ResettableEventBus has. Akito -- http://groups.google.com/group/Google-Web-Toolkit-Contributors

Re: [gwt-contrib] Memory leak in ResettableEventBus
Thanks, I'll look at this today. On Mar 24, 2011 9:08 AM, Akito Nozaki akito.noz...@gmail.com wrote: Not sure how this contributing thing works. I was assuming that things get pushed here automatically if I created an issue at the review site. I uploaded some code to deal with memory leak in ResettableEventBus. Mainly with nested ResettableEventBus and passing ResettableEventBus into ActivityManager. http://code.google.com/p/google-web-toolkit/issues/detail?id=5700 http://gwt-code-reviews.appspot.com/1388804/ Really simple fix and would really love to get this included in the next release as I keep having to patch/include my own ResettableEventBus in my code. As I was working on this code I noticed that CountingEventBus has the same bug but I'm guessing that only gets used in tests? Also I wasn't sure how to write a test that check the internal state. Mainly to test for the memory leak the current ResettableEventBus has.

Re: [gwt-contrib] Re: Move com.google.gwt.requestfactory to com.google.requestfactory (issue1383808)
Yeah, Dan made the valiant effort here but I don't think it's practical. I don't feel bad asking users to change import statements to pick up bug fixes. It would be great if we can get this into the 2.3 rc. On Mar 24, 2011 7:05 AM, Daniel Rice (דניאל רייס) r...@google.com wrote: I spent a few days attempting this -- it's not so simple. For example: 1) Enums can't extend Enums. Several public types contain nested Enums. 2) If a type oldA extends newA, and a method in it returns an instance of oldA, you cant simply delegate to the implementation in newA since that will return a newA, which is not an instanceof oldA. So you need to write wrappers for everything. 3) It's unclear to me how inheritance works on annotations 4) Generators will have to be modified to work off the different annotation types I think there were other problems as well that I can't recall at the moment. My belief is that continuing with this approach would have polluted the new code base with special cases to handle parallel enums and annotations. I spoke to Ray about it and he agreed to the plan of leaving a snapshot in the old location and trying to remove it in the next release.

The old types should extend the new types and where that isn't possible, the old type should be rewritten as a delegate. Anything in the rebind or **/impl packages can be a straight move. They're not public types. http://gwt-code-reviews.appspot.com/1383808/ -- http://groups.google.com/group/Google-Web-Toolkit-Contributors -- http://groups.google.com/group/Google-Web-Toolkit-Contributors

I'm not 100% sure what time you're trying to save in here by putting this in a thread; could you add a comment in the body of the thread as to what is expensive? I guess its the calculation of contentId. Warning - I think you're in thread unsafeness land in ResourceCompilationUnitBuilder when the compiler tries to lazily compute contentId, waiting until the source is read. Did you measure the amount of time saved?
