Re: Developers, please don't ignore reported GWT issues.
I have been frustrated with this as well and voiced my concern before. But all they keep on doing is adding features that most of us don't need. GWT is great, but there is a lot of old stuff in there that is half baked and nobody in the GWT team seems to be concerned with actually fixing bugs. When I complained about it the only answer (if any) I get is: you are free to send us a patch. Most of us don't have the time, or even the right to spend our time on working on code for google during our day jobs. And in the evening we need to take care of our family so fixing anything taking more than a few lines of code is totally impossible. I managed to patch one of the issues I reported, but some things are hard to fix unless you really know the GWT internals very well. There is a bug in the Event dispatching after opening a popup in IE and I really don't know how to fix this one since it goes really deep into the root event handling implementation. There is no developer docs available that explains the architecture and the devs that created the code in the first place are doing other things. I filed the bug report, I wrote in GWT and GWT contrib newsgroups and got 0 responses... This is the one: http://code.google.com/p/google-web-toolkit/issues/detail?id=4938 From what I read on google culture it seems like you only get rewarded for writing new stuff, not fixing old stuff (unless it affects a google product launch). -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: I need suggestions for compositeCell selection
My bad. The description might have been insufficient.
I have an overwritten multiselection model because I want to select
multiple items. I'm not sure if this makes any difference but I
mentioned it just in case.
My problem is how to tick check box when I click on the imageCell when
the item is already selected.
So once again. I know how to select an item and tick the checkBox by
clicking on the image cell - I use custom eventTranslator and make the
hasCell with a single checkBox depending on selection and not handle
selection on it's own.
Now I replaced the hasCell with single checkBoxCell with hasCell
containing a cell made of 3 custom checkBoxes ( I added a name
attribute describing resolution so that I know which one was selected
when change event is fired).
I added lastChanged property to the underlying object to remember what
fired the event. I set the property in eventTranslator.
I want the item to be selected and backgroud color changed if at least
one of the checkBoxes is ticked= unticking single checkbox doesn't
necessarily lead to deselecting an item.
I also want it to be selected when the imageCell is clicked. In that
case the default checkBox should be ticked.
Clicking on checkBoxes to select image is simple. I can click on the
imageCell and tick the default resolution this way but only if the
item hasn't been selected yet.
If it's already selected the cell is not rerendered
.
I thought that the problem was in selectionModel.resolveChanges
if (selected) {
if (oldValue == null || !oldValue.equals(object)) {
..
It only fired event if there was no selection or other item had been selected.
I needed it to fire a changeEvent if other checkBox in the same item
was ticked. In other words when property not the object changed.
So I replaced that code with if (oldValue == null ||
object.lastChange()!= null)
So my model is firing the event now but it gets lost somewhere. The
cellList isn't calling renderRowValues = the cell isn't re-rendered=
box isn't ticked
To sum up hacking things is never good idea and my solution doesn't work.
How should I implement this properly?

Re: Using Multiple Panels
i dont know if this is important but you also have a typo:
you are saying in your html page you have:
mainData1 and mainData2
and you are trying to get elements with ids: mailData1, mailData2
RootPanel.get(mailData1).add(mainPanel1);
RootPanel.get(mailData2).add(mainPanel2);

Continuous editing of a proxy with the Editor framework
Hi there,
It seems that the Editor framework implies one-time editing of a
proxy, and once you call flush() of the driver you can't get the edited
proxy back with updated values until it's persisted. Or am I wrong?
I need such feature to make a persistent UI. The idea is to have a proxy object
for UI state and persist it each time the user changes UI state. The thing is
when the editor request is in process the UI state still can be changed and
these changes will be lost. Is it GWT-style solution or is my design completely
wrong?
Hope this snippet will make sense:
1: *class* UIStateProxy *extends* EntityProxy *{* 2: *boolean*
getShowToolbar*(**)**;* 3: *void* setShowToolbar*(**)**;* 4: *}* 5: 6:
*class* UIStateWorkflow *implements* EditorUIStateProxy *{* 7: 8: @UIField
9: CheckBox showToolBarEditor*;*10: 11: */* driver initialization and other
things */*12: 13: @UiHandler*(*showToolBarEditor*)*14: *void*
onSetShowToolbar*(*ValueChangeEventBoolean event*)* *{*15:
driver*.*flush*(**)**.*fire*(**)**;*16: */* Now UI state is sent to the
server, but what to do next?17: /* It is neither possible to get edited
proxy and restart the editor nor abort the request */*18: *}*19: 20: *}*
Thank you in advance!

Re: iframe with GWT
So I found this
link http://bealetech.com/blogs/sean/2010/01/embedding-html-document-iframe-gwt
and I got it to work using these functions:
final IFrameElement iframe = Document.get().createIFrameElement();
FlowPanel innerBox = new FlowPanel() {
@Override
protected void onLoad() {
super.onLoad();
// Fill the IFrame with the content html
fillIframe(iframe, contentHtml);
// Add a HEAD element to the IFrame with the appropriate CSS
addHeadElement(iframe, cssUrl);
}};
innerBox.getElement().appendChild(iframe);
*and *
private final native void fillIframe(IFrameElement iframe, String content) /*-{
var doc = iframe.document;
if(iframe.contentDocument)
doc = iframe.contentDocument; // For NS6
else if(iframe.contentWindow)
doc = iframe.contentWindow.document; // For IE5.5 and IE6
// Put the content in the iframe
doc.open();
doc.writeln(content);
doc.close();
}-*/;
I tried to get the head function on that page to work, but wasn't sure how to
pass in the HTML and write it to the head element. Right now I'm just using
div style=background-color:red; font-size: 18px;Hello World/div to get
the styles to work with the divs I need them to.
I end up with this in the dom:
diviframehtmlhead/headbodydiv
style=position:fixed;top:0px;left:0px;color:red;background-color: blue;
font-size:44px;Hello World/div/body/html/iframe/div
It works but I would imagine there's a better way.

Trouble with GWT 2.0.4, RPC and non root account
Hi. I've the following scenario: - NetBeans IDE 7.0 with GWT4NB - Mid sized application running GWT 2.0.4 with some extensions (like GWT Math, for BigDecimals) - Apache Tomcat 7.0.11 and Apache Tomcat 7.0.20 Exactly same setup running on Windows works great. When running in Linux, if I run as root, works great. As my limited user, throws the following server side exception: GRAVE: Exception while dispatching incoming RPC call com.google.gwt.user.client.rpc.SerializationException: java.lang.reflect.InvocationTargetException at com.google.gwt.user.server.rpc.impl.ServerSerializationStreamWriter.serializeWithCustomSerializer(ServerSerializationStreamWriter.java: 760) at com.google.gwt.user.server.rpc.impl.ServerSerializationStreamWriter.serializeImpl(ServerSerializationStreamWriter.java: 723) at com.google.gwt.user.server.rpc.impl.ServerSerializationStreamWriter.serialize(ServerSerializationStreamWriter.java: 612)... I've tracked it down to a BigDecimal data type. Why does this happen only with non root accounts? I have already checked permissions on Tomcat, Tomcat Base, and NetBeans, and they are all fine. I really suspect that is something related to permissions, but I have no clue where to look for. I've been searching for 2 days without success.

CellList navigation

Fundamental MVP Problem
I've got my MVP Project more or less running. But now I more and more and more get into problems with Browser Event Handling (Click, MouseOut/Over, etc.). And connected with that some other things too. I could be that my structure is no true MVP, and maybe that's the cause for my problems?! But have a look yourself: I have a News section. It consists of - NewsPresenter + Display - NewsItemPresenter + Display + Model The first little question: Where in the MVP structure I should fetch the data from the server? Inside the presenter or should I write some kind of controller that handles ONLY the server connection for news? (For instance I could say: 'give me all news' or 'give me the next 5 news after id 5' and 'update id 3 with the following model'). Actually it's all inside the NewsPresenter, it works, but it's bad for the overview... Now my real problems: First all news I'd like to display a fetched from the server (or cache). Then the NewsPresenter has a HashMapNewsItemId, NewsItemPresenter. It takes each NewsItemModel and calls 'new NewsItemPresenter(model)' and puts it into the HashMap. So I have a cache which is pretty handy. Afterwards the NewsPresenter attaches those NewsItemPresenters to the content area of the NewsDisplay. I think that's pretty straight forward. Now each NewsItemDisplay has Click/MouseOver/MouseOut Handlers. And as Google told us, it's better to have a single Handler than one Handler for each item. Right now every NewsItemDisplay has it's own Handlers and tells it's presenter (via well designed Interface) which button was clicked. But I'd like to have the NewsPresenter (or NewsDisplay) to handle such things with a single EventHandler. Sure I could add the ClickHandler to the NewsDisplay but then I don't know which of my items was clicked and even harder: Which button inside of an item was clicked. It would be pretty cool, if someone could give me some advise (or example Code) on how to achieve this. :) -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

GWT Mail Example- StackLayoutPanel Selection Event (The Shortcuts)
Hi all, I'm new to GWT and trying to modify the example GWT Mail application (http://gwt.google.com/samples/Mail/Mail.html) to when I click on one of the shortcut tabs on the left (ie Contacts, Mail etc), it will change the MailList part of the application (basically the maillist table) to be populated with different data. Eg when I click on the Tasks 'box' not only will it animate the left stack layout panel but i would like it so the table (MailList) that has 'subject', 'Email', and 'subject' as table headings to change and table cleared and have eg tasks information in the table instead. I have figured out how to change the table headers and the contents but I cant seem to figure out how to do it on an event when one of those buttons on the left are clicked/selected. Any help would be greatly appreciated. Thanks. -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: Permutation, code splitting and deferred property
Thanks David for the follow-up.
Could this be a result of the new PersistentUnitCache / generator caching
stuff?
I tried having a different generator class for each value but I still
had the same issue.
Also, Soft Permutations would cause this, so make sure those are not on.
I don't use the collapse-property tag so if I'm correct, they aren't
soft permutations.
I was able to reproduce the issue using replace-with tag in a simple
case. I had the following code:
public class Widget1 … {}
public class Widget11 extends Widget1 {
public void oneMethod(){
GWT.runAsync(new RunAsyncCallback {
@Override
public void onSuccess() {
Widget w2 = new Widget2();
...
}
...
}
….
}
public class Widget12 extends Widget1 {
public void oneMethod(){
GWT.runAsync(new RunAsyncCallback {
@Override
public void onSuccess() {
Widget w2 = new Widget2();
...
}
...
}
….
}
and have the following configuration:
replace-with class=com.test.client.Widget11
when-type-is class=com.test.client.Widget1/
/replace-with
replace-with class=com.test.client.Widget12
when-type-is class=com.test.client.Widget1/
when-property-is name=user.agent value=gecko1_8 /
/replace-with
and then I just create a widget1 in my entry point:
public void onModuleLoad() {
w1 = GWT.create( Widget1.class );
...
}
When I look at the soyc report, for any permutation, GWT detects 2
split points and all the code of Widget2 is in the left-over fragment.
I'm not sure why GWT detects 2 split points because when you look at
the full code size report, only one of the 2 classes is here (which is
the expected behavior).
If it can help, you can find the code here:
http://mvp4g.googlecode.com/svn/temp/gwt-example2.zip
Also this happens only with gwt-2.4.0 but it works fine with
gwt-2.3.0. Could it be a bug with gwt-2.4.0 (but I have to admit it is
a pretty rare case)?
I found one workaround in my case by creating an extra class that
contains the split point:
public class SplitWidget2(){
public void split(RunAsyncCallback callback){
GWT.runAsync(callback);
}
}
and then in Widget11 and Widget12:
public class Widget11 extends Widget1 {
public void oneMethod(){
newSplitWidget2().split(new RunAsyncCallback {
@Override
public void onSuccess() {
Widget w2 = new Widget2();
...
}
...
}
….
}
Thanks for your help,
Pierre

Vertical Scroll bar on the page in GWT
HI All, I am pretty new to the GWT world.I am trying to get the vertical scrollable pages. I am using GWT 2.4 and UiBinder to achieve my page layouts. Throughout my application I have a header section, main content area section and footer section. I have created a separate composite for header , footer. I am using the DockLayoutPanel. To the north of the dock panel and I am adding my header , to south of dock panel my footer and to the center of dock panel all my pages created using UiBinder. UiBinder pages make use of the HTML panel . My problem is as my main content area grows, I am not able to get the vertical scroll on the page. One solution for this is using ScrollPanel as parent of HTMLPanel in in my UiBinder pages. But then only my main content area gets the vertical scroll page, not the hole web page itself. Please help me to get the vertical scroll bar. Regards, Vikram -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: Using window.open(), Chrome and extensions in GWT project..
I can only PARTLY answer my own question: in a Chrome window opened
via open.window() you can right-click on the title bar and select
open in tab. this returns the window to traditional form and exposes
the extensions bar. This is an extra step and we'd still love to see
if extensions bar can be made visible by default from window.open().

Re: Using window.open(), Chrome and extensions in GWT project..
Adding another question to this: How can i get the handler for this opened
window?
Javascript's window.open() returns a reference to opened window.
However, GWT's Window.open() doesn't, so you'll have to use JSNI here

GWT Designer - Support to reference CSS from ui.xml as well as CSSResource

Upgrade issues: Eclipse plugin to 2.4
I encountered a couple of unexpected problems when I upgraded my plugin for Eclipse (Helios) to v2.4 -- I finally got everything resolved, but I thought it might be worth sharing my experience. 1) The new plugin includes the ability to develop in GWT for Android native apps, but this introduces a new and unexpected dependency during the install: you have to also install the ADT plugin from http://developer.android.com/sdk/eclipse-adt.html (and then, in order to use the ADT plugin if you so desire, you need to install and link an Android SDK...). However, the ADK Plugin site is not on the standard software sources list for Eclipse, so you need to add it. Well, actually, you can either add the ADK plugin software site (and thus download and install the ADK plugin) or uncheck the Android GWT package when you upgrade the GWT plugin (but then you can't compile to native Android). I tried both ways, and they both work. 2) I had several projects which I had written using the GWT 2.3 plugin, and when I upgraded, they all started showing an error in the .../war/WEB-INF/lib/ directory. Oddly, I could still compile and run everything, but there was always this nagging error flag. It turns out that the appengine JAR files in those directories weren't updated as part of the upgrade. The newer, v1.5.4 JAR files need to replace the older, v1.5.2 JAR files. I had to do this by hand. I discovered the problem by starting a new project and comparing the contents of the directory with that in an older project. I hope this helps other people deal with upgrade issues. -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Indexed DB/WebStorage in GWT?
Howdy, all, Is anyone using webstorage or indexedDB client side data storage with GWT? Pointers to projects appreciated... Aside: I note that the WebStorage group reached an impasse and stopped supporting the spec last fall. I note further that http://www.w3.org/TR/IndexedDB/ seems to be alive and kicking, but a brief reading seemed to indicate that this is a great system for key-object mappings, but not so great for the generic sql case of select rows from foo where name is blah group by this order by that kind of queries. ( might be wrong - section 3.1.3 keys can be DOMStrings. Since can supply a keyrange to an index, you may be able to generate the kind of selects I am used to, as long as you can generate an index such that the result of that query would be expressable as either indexkey==foo or low indexkey hig. Aside aside, does anyone have real world experience? I do not mind if the results only work on Chrome/FF/Safari, but IE would also be cool.

Re: Indexed DB/WebStorage in GWT?
As Jeff points out, Storage is supported in GWT today. Storage is the HTML5 key/value pair datastore and has a 5mb limit (unless you are installed via the Chrome Web Store). John LaBanca has a good overview (that is pretty entertaining) here: http://www.youtube.com/watch?v=KEkR1ox_K10 We don't currently have an IndexedDb wrapper. IndexedDb (http:// www.w3.org/TR/IndexedDB/) is a successor to the defunct WebSQL and is a much more powerful datastore than Storage, supporting queries and such. GWT support for IndexedDb will require some serious work and I don't know of anyone looking into it at the moment.

java.text.MessageFormat working on client?
Hello all,
I'm relatively new to GWT. I'm actually developing a web application
using SmartGWT, don't know if you've heard of it.
Anyway, I'm trying to format some internationalized messages. In the
server, I'm using the Java built-in support, through
java.text.MessageFormat class. But after doing some research, I
understood that this would not work on the client side. But when I run
the following code in a client-side class:
-
String message = Number: {0};
Log.debug( [Is Client: + GWT.isClient() + ] Before formatting: +
message );
MessageFormat formatter = new MessageFormat( message );
message = formatter.format( new Object[] { 2.5 } );
Log.debug( [Is Client: + GWT.isClient() + ] After formatting: +
message );
-
I get the following output:
-
(WebApplicationContext.java:51) 2011-10-05 15:07:19,662 [DEBUG] [Is
Client: true] Before formatting: Number: {0}
(WebApplicationContext.java:56) 2011-10-05 15:07:19,690 [DEBUG] [Is
Client: true] After formatting: Number: 2,5
-
This is using my default locale, 'pt_BR'. But I can even change it
with:
-
Locale locale = new Locale( en, US );

Re: java.text.MessageFormat working on client?
Is the class and the method do you need are

yes.
2011/10/5 Thiago Coraini tcora...@gmail.com
Hello all,
I'm relatively new to GWT. I'm actually developing a web application
using SmartGWT, don't know if you've heard of it.
Anyway, I'm trying to format some internationalized messages. In the
server, I'm using the Java built-in support, through
java.text.MessageFormat class. But after doing some research, I
understood that this would not work on the client side. But when I run
the following code in a client-side class:
-
String message = Number: {0};
Log.debug( [Is Client: + GWT.isClient() + ] Before formatting: +
message );
MessageFormat formatter = new MessageFormat( message );
message = formatter.format( new Object[] { 2.5 } );
Log.debug( [Is Client: + GWT.isClient() + ] After formatting: +
message );
-
I get the following output:
-
(WebApplicationContext.java:51) 2011-10-05 15:07:19,662 [DEBUG] [Is
Client: true] Before formatting: Number: {0}
(WebApplicationContext.java:56) 2011-10-05 15:07:19,690 [DEBUG] [Is
Client: true] After formatting: Number: 2,5
-
This is using my default locale, 'pt_BR'. But I can even change it
with:
-
Locale locale = new Locale( en, US );
formatter.setLocale( locale );
-
and then I would get the output:
-
(WebApplicationContext.java:52) 2011-10-05 15:12:08,592 [DEBUG] [Is
Client: true] Before formatting: Number: {0}

Declarative UI + Google Maps
Hi I'm trying to use Google Maps in my project so I add
inherits name='com.google.gwt.maps.GoogleMaps' /
in the gwt.xml file. I use deferred binding for create the UI and the
View.ui.xml file's code is:
!DOCTYPE ui:UiBinder SYSTEM http://dl.google.com/gwt/DTD/
xhtml.ent
ui:UiBinder xmlns:ui=urn:ui:com.google.gwt.uibinder
xmlns:g=urn:import:com.google.gwt.user.client.ui
xmlns:p1=urn:import:com.google.gwt.user.cellview.client
xmlns:p2=urn:import:com.google.gwt.maps.client
ui:style
.important {
font-weight: bold;
}
/ui:style
g:VerticalPanel ui:field=rootPanel width=100% height=100%
p2:MapWidget ui:field='map' /
/g:VerticalPanel
/ui:UiBinder
The View.java file's code is:
import com.google.gwt.core.client.GWT;
import com.google.gwt.maps.client.MapWidget;
import com.google.gwt.uibinder.client.UiBinder;
import com.google.gwt.uibinder.client.UiField;
import com.google.gwt.user.client.ui.Composite;

import com.google.gwt.user.client.ui.Label;
import com.google.gwt.user.client.ui.MenuBar;
import com.google.gwt.user.cellview.client.CellTable;
public class View extends Composite {
private static ViewUiBinder uiBinder = GWT
.create(ViewUiBinder.class);
@UiField VerticalPanel rootPanel;
@UiField MapWidget map;
interface ViewUiBinder extends UiBinderWidget, View {
}
public View() {
initWidget(uiBinder.createAndBindUi(this));
}
}
The problem is when i switch from the code view to the design view
elipse show me this error:

GWT localization(i18n): make possible read on server side com.google.gwt.i18n.client.Messages (using spring on server side)
*Problem: *
Required ability to have access to GWT client
com.google.gwt.i18n.client.Messages files on server side(e.g. inside
Servlet).
*Problem reason: *
In my case I needed to generate the PDF representation of the web page +
save some string values in DB(when someone posts comment).
*Desired behaviour*:
Have a single MessageResource provider that can be executed from both server
side and from client side:
*Solution:
*
1. First of all *make sure that all GWT message resources are generated
from *.properties file via com.google.gwt.i18n.tools.I18NSync tool*(or
you have to synchronise i18n .properties files with GWT message interfaces
all the times). Otherwise, if you just using interfaces without using
*.properties files, this approach will not work.
2. Now, let's *educate the server how to read GWT i18n *.properties*:
1. I am using spring framework as server side, so in this example we
will educate Spring where the GWT's i18n *.properties are stored in the
app:
bean id=messageSource
class=org.springframework.context.support.ReloadableResourceBundleMessageSource
property name=basenames
list
valueclasspath:messages/value
valueclasspath:error_messages/value
valueclasspath:/blabla/project/client/resources/i18n/messages/GlobalRes/value
/list
/property
property name=defaultEncoding value=UTF-8/
/bean
the classpath:/blabla/project/client/resources/i18n/messages/GlobalRes
is full path to GlobalRes.properties file. Make sure you include this
file
in classpath when yo compile your project.
2. Basically, after telling spring
ReloadableResourceBundleMessageSource where to take the resources is
pretty
enough to have GWT messages being accessed on server side, by just
injecting
messageSource into any place on server and using
messagesCourse.getMessage(messageCode,args[],locale). But this is not
what
we want to achieve. The aim is to have the same message resource provider
that can be executed on server and on client side the same way.
3. So next, let's just create this Messages Provider that can be
executed on both client and on server side:
public class MessageResourceProvider {
public static GlobalRes GLOBAL_RES;
public static GlobalRes SERVER_GLOBAL_RES;
static {
try {
GLOBAL_RES = GWT.create(GlobalRes.class);
} catch (Exception e) {
}
}
public static GlobalRes getGlobalRes() {
if (GLOBAL_RES != null) {
return GLOBAL_RES;
} else {
return SERVER_GLOBAL_RES;
}
}
}
First of all, make sure that MessageResourceProvider is stored under *.*
client.** package, so GWT client side will be able to access it. So here
we have two instances for providing resources: one for server part, the
other one for client side. With client side everything is clear: we just try
to call GWT.create(GlobalRes.class) in static block and if it's successfully
executed(which actually means it executed on client side) then the
getGlobalResources will return client version of GlobalRes.
But what about SERVER_GLOBAL_RES? Where should it come from? Obviously -
it should come from server.
4. Ok, let's *tell server part to how inject SERVER_GLOBAL_RES into
MessageResourceProvider wher the server starts*.
in order to do that I just added listener in my* web.xml*
listener
listener-class
org.kuali.lum.cmi.server.util.CmiServletListener
/listener-class
/listener
so application will call this listener at startup time.
the listener code is very simple:
public class CmiServletListener implements ServletContextListener {
@Override
public void contextInitialized(ServletContextEvent sce) {
ServerMessageResourceFactory serverMessageResourceFactory =
(ServerMessageResourceFactory)
WebApplicationContextUtils.getWebApplicationContext(sce.getServletContext()).getBean(serverMessageResourceFactory);
MessageResourceProvider.SERVER_GLOBAL_RES =
serverMessageResourceFactory.getGlobalRes();
}
@Override
public void contextDestroyed(ServletContextEvent sce) {
}
}
As you see at startup time I just set MessageResourceProvider's
SERVER_GLOBAL_RES which I take from
serverMessageResourceFactory.getGlobalRes().
5. So this is almost it, except I haven't described the most tricky and
interesting part: *how the serverMessageResourceFactory.getGlobalRes()
will return the com.google.gwt.i18n.client.Messages resources instance that
can de executed from server side and why hadn't we
Development Mode Hangs

In the Development Mode tab, I get the message Development mode is loading... and Waiting for launch URLs. This remains indefinitely until I finally shut down the process. When I change the logging level to DEBUG I see that it goes to Loading modules and then sticks on the lone module in my project. It is a very small project, literally just 3 small panels. When I build the WAR and deploy it within JBoss, it runs fine. But when I try to debug, it just hangs. Anybody have any idea of where I can try to look to figure out what's happening?

[gwt-contrib] More control over split point fragments
Hi,
I'm finding it too difficult to keep code out of the left overs fragment. I
have a single application which has a split point for every html page. Some
of my pages use Widgets and other don't but the left overs fragment contains
all the code to support Widgets which is a huge drag.
Imagine I have three split points for three pages:
Initial - A
- B
- C
A and B use Widgets and so I want all the Widget related stuff to go in a
common fragment. C does not use Widgets at all (perhaps GQuery) so it
should not have to download the tons of java.util classes and other cruft it
doesn't need.
I first tried to make a WidgetFactory class using the Async Provider
pattern outlined in the docs. e.g.
WidgetFactory.access(new Callback() {
public void widgets(WidgetFactory widgets) {
// build ui with widgets
Label label = widgets.label(hi);
}
});
But this does not work because *all *the code that uses the widgets ends up
in the factory's split point. The callbacks are all called directly from
the same split point as the widget factory.
I've tried this too:
WidgetFactory.access(new Callback() {
public void widgets(WidgetFactory widgets) {
build(widgets);
}
});
// try to force the building code to stay in this fragment
build(null);
But then all the Widget plumbing code goes in the left overs fragment
(because its used in A and B). I want all the widget constructor code (and
other methods common to A and B) to go in its own fragment.
So my question is, is there any good way to put Widget code into a common
fragment?
I just can't think of any good way to do this currently. Is the left overs
fragment doomed to grow forever?
The only approach I can think of is not good for many classes. I could
define a new fragment W that loads A and B and preloads all widget code
that will be used later:
Label l = new Label();
l.setText(null);
l.setTitle(null);
l.addClickListener(null);
But this is not practical to do for every method in every class that will be
used.
There must be a better way!

[gwt-contrib] Re: More control over split point fragments
I think currently the left over fragment will grow forever if you introduce new commonly used classes (used in more than one split point). Maybe a potential solution will make it into one of the next GWT releases.

Re: [gwt-contrib] More control over split point fragments
You could try making a split point which contains other split points,
something like this:
I = Initial Fragment
W - Split point from which all Widget using splitpoints exist
W1 - Widget using split point 1
W2 - Widget using split point 2
G - Split point from which all GQuery using code exists
G1 - GQuery split point page 1
I don't remember if this is so, but if all Widget using code ends up
exclusive to W, then it won't be in the leftovers fragment.

public void widgets(WidgetFactory widgets) {
build(widgets);
}
});
// try to force the building code to stay in this fragment
build(null);
But then all the Widget plumbing code goes in the left overs fragment
(because its used in A and B). I want all the widget constructor code (and
other methods common to A and B) to go in its own fragment.
So my question is, is there any good way to put Widget code into a common
fragment?
I just can't think of any good way to do this currently. Is the left overs
fragment doomed to grow forever?
The only approach I can think of is not good for many classes. I could
define a new fragment W that loads A and B and preloads all widget code
that will be used later:
Label l = new Label();
l.setText(null);
l.setTitle(null);
l.addClickListener(null);
But this is not practical to do for every method in every class that will be
used.
There must be a better way!

Re: [gwt-contrib] Re: More control over split point fragments
The problem of detecting common code and putting them into shared fragments of certain size is related to the Graph Partitioning Problem, like many compiler problems, which is NP-Complete. That doesn't mean it can't be done, Alan Leung is working on this for the next release, it just means it has to be done with heuristics, and it takes time to get those right. Basically, you can make a graph, where each vertex is a split point, and each edge between vertices represents a shared fragment of code that is alive in both. This graph is quite tangled up for real code bases, but the general idea is to try and find split points that share lots of common code, and merge them, or move some shared code to the initial fragment, or the leftovers fragment as to permit merging to proceed, so that a whole bunch of other code can be made exclusive to the merged fragment that would otherwise be forced into leftovers. I've probably bungled the explanation, Alan can probably describe it in more detail. -Ray On Wed, Oct 5, 2011 at 11:02 AM, John Tamplin j...@google.com wrote: On Wed, Oct 5, 2011 at 12:52 PM, John Patterson jdpatter...@gmail.com wrote: That seems likes a step in the right direction - but ideally there would be some algorithm that can put common code into new shared fragments.

Re: [gwt-contrib] Re: More control over split point fragments
I think Ray described it perfectly. I am current in process of make the change he described. While I have the basic idea implemented (minus some bugs I am current fixing), the trick is to know what are the right parameters for doing these kinda of things. Example 1) How many Async point do we merge? You can imagine if you merge all N spit points, you'd end up with a zero size leftover. 2) How big should a fragment be before we stop merging? You don't want to merge too much so your exclusive fragment become bigger than the leftover. I have studied Lex Spoon's writeup extensively a few weeks back. While I do believe it is beneficial to leftover code size, when I bought it up with some of the internal projects, they believe the cache-ability lost with multiple leftover fragments is not something they'd trade off. That's why I went down the fragment merging route. -Alan On Wed, Oct 5, 2011 at 11:36 AM, Ray Cromwell cromwell...@google.comwrote: The problem of detecting common code and putting them into shared fragments of certain size is related to the Graph Partitioning Problem, like many compiler problems, which is NP-Complete.
