Issue with ListGrid clearCriteria method
i am using Listgrid of smartgwt api. i have set filter editor on the
list grid using setShowFilterEditor(). On UI, i can filter out the
list data from the particular columns using filter editor which is
shown on top of listgrid. till this, everything works fine. but
problem starts after this. my ListGridRecords are of type
ScreenInstanceGridRecord.
I cleared out the filter criteria before getting the ListGridRecord
from the ListGrid using method clearCriteria(), so that i can save all
the records to database ie. unfiltered records. when i try to get
records from the listgrid using getRecordList(), 1000 Dummy records
are added on the fly on first iteration, all my populated records are
ignored . and i need here is records of ScreenInstanceGridRecord type.
but on second iteration, i am getting my populated records which is of
ScreenInstanceGridRecord type. why this problem is occurring. i should
be getting ScreenInstanceGridRecord on the first iteration itself when
i try to get records from the ListGrid using getRecordList(). i am
getting no idea about this weird thing. any help from your side is
most welcome.. i am giving u piece of code which give u an idea where
i am getting problem
public void onModuleLoad() {
DataSourceIntegerField idSource = new
DataSourceIntegerField(id);
idSource.setPrimaryKey(true);
idSource.setHidden(true);
DataSourceTextField nameSource = new
DataSourceTextField(name);
DataSource ds = new DataSource();
ds.setFields(idSource, nameSource);
ds.setClientOnly(true);
final ListGrid grid = new ListGrid();
grid.setDataSource(ds);
grid.setShowFilterEditor(); // problem lies here
grid.setWidth(600);
grid.setHeight(400);
grid.setAutoFetchData(true);
grid.setAlternateRecordStyles(true);
grid.setShowAllRecords(false);
Button savebutton = new Button(Save);
saveButton.addClickHandler(){
grid.clearCriteria();
RecordList records = grid.getRecordList();
int length = recordList.getLength();
// On First Iteration, this method always giving me 1000 dummy
records. its doesnt matter how many records are populated in the grid.
but on second iteration, it is giving me right records length.
}
i don't know what the heck is happening here. i am very confused for
past 3 days. please give me some light on it.

Point taken, the docs do make it very clear its a pattern and one way of implementing it, and that its best suited for large scale projects and why. Though reading through the User Guide, you could be forgiven for thinking 'This is the way I should go with my app!', especially if you decide to use UiBinder, as the Activity/Places MVP article uses it and is almost like a tutorial on building an app. I guess its just because the other tutorial in the User Guide, the Stock Watcher, doesn't use UiBinder, which is a very attractive feature to anyone new to GWT.

If you value theory and purity more than pragmatism and productivity, then yes, it probably violates the pattern, as it doesn't use the observer pattern.

Performance Tip for IE browsers : Java garbage collection is NOT Javascript garbage Collection
Hi All,
I've been working on GWT for a while now and noticed something important and
peculiar.
In GWT you code in Java and almost automatically assume Java garbage
collection (because that's how you code).
In this code sample:
http://code.google.com/webtoolkit/doc/latest/DevGuideServerCommunication.html#DevGuideRemoteProcedureCalls
you'll see that the callback is created like the code snippet below. I
imagine that every GWT project will implement it like this.
The Use Case: Fill data in the new CellTable widget. The size of the data
varied from 100 to 600 records.
If the onSuccess results in a lot of data and this event/callback is invoked
lots of times (actually 3 to 5 times is enough) , on IE6, IE7,IE8 and IE9
there will be performance degradation. In other browsers
like Chrome, Firefox and Safari there is no performance loss noticed.
After reading Joel Webber's note on Performance, I found out that it's not
the component (like the CellTable) that causes this behavior,
but it was the callback creation. It seems that IE doesn't know how to
garbage collection the callback. So each time this new AsyncCallback is
performed,
a memory leak occurred in IE browsers.
Since the Callback is stateless, we decided to create the callback only once
(*static *variable) and there was no performance loss anymore.
After clicking for a while, the performance was the same (even after
inspecting the results of some measurement tools).
This worked for us and even IE6 is blazingly fast. IE9 is now even faster
that Chrome! No need for Chrome Frame Plugin (some organizations don't allow
Plugins at all, think about that!)
Hopefully this tip works for you.
And Yes we have GWT in production. That company's browser policy is to use
IE (now on 7, moving to 8). So this had to work or otherwise , it was a huge
showstopper!
GWT applications do perform (even in older browsers), just make sure that
critical parts of your code are carefully reviewed (especially on the
new).
AsyncCallback callback = new AsyncCallback() {
public void onSuccess(Void result) {
// do some UI stuff to show success
}
public void onFailure(Throwable caught) {
// do some UI stuff to show failure
}
};
// (3) Make the call...

Re: Performance Tip for IE browsers : Java garbage collection is NOT Javascript garbage Collection
Thanks for share!!!
2011/9/26 Rokesh rjan...@gmail.com
Hi All,
I've been working on GWT for a while now and noticed something important
and peculiar.
In GWT you code in Java and almost automatically assume Java garbage
collection (because that's how you code).
In this code sample:
http://code.google.com/webtoolkit/doc/latest/DevGuideServerCommunication.html#DevGuideRemoteProcedureCalls
you'll see that the callback is created like the code snippet below. I
imagine that every GWT project will implement it like this.
The Use Case: Fill data in the new CellTable widget. The size of the data
varied from 100 to 600 records.
If the onSuccess results in a lot of data and this event/callback is
invoked lots of times (actually 3 to 5 times is enough) , on IE6, IE7,IE8
and IE9 there will be performance degradation. In other browsers
like Chrome, Firefox and Safari there is no performance loss noticed.
After reading Joel Webber's note on Performance, I found out that it's not
the component (like the CellTable) that causes this behavior,
but it was the callback creation. It seems that IE doesn't know how to
garbage collection the callback. So each time this new AsyncCallback is
performed,
a memory leak occurred in IE browsers.
Since the Callback is stateless, we decided to create the callback only
once (*static *variable) and there was no performance loss anymore.
After clicking for a while, the performance was the same (even after
inspecting the results of some measurement tools).
This worked for us and even IE6 is blazingly fast. IE9 is now even faster
that Chrome! No need for Chrome Frame Plugin (some organizations don't allow
Plugins at all, think about that!)
Hopefully this tip works for you.
And Yes we have GWT in production. That company's browser policy is to use
IE (now on 7, moving to 8). So this had to work or otherwise , it was a huge
showstopper!
GWT applications do perform (even in older browsers), just make sure that
critical parts of your code are carefully reviewed (especially on the
new).
AsyncCallback callback = new AsyncCallback() {
public void onSuccess(Void result) {
// do some UI stuff to show success
}
public void onFailure(Throwable caught) {
// do some UI stuff to show failure
}
};
// (3) Make the call...

Re: Custom cell, not responding to mouse clicks
Override the getConsumedEvents() in AbstractCellC, and specify
event type as click. You might also set preventDefault(),
stopPropagation() property in NativeEvent.
@Override
public Set getConsumedEvents()
{
printNative( getConsumedEvents() called );
return Collections.singleton(click);
}
public void onBrowserEvent(Cell.Context context, Element parent,
Object value, NativeEvent event)
{
event.preventDefault();
event.stopPropagation();
printNative(click NativeEvent + event);

Re: Performance Tip for IE browsers : Java garbage collection is NOT Javascript garbage Collection
interesting,
Would it be possible to implement this optimization at the compiler level,
so that programmers don't have to care about this? I mean, only on the IE
permutations, or for all permutations if it doesn't have negative effects on
other browsers
Not something specific to callback, but for anonymous classes in general

sevaral bugs with cssresource (try not to repeat known issues)
Hi,
@if user.agent
I try to make conditional if with user.agent in cssresources, i make
this example and it doesn' work in ie7 :
@if user.agent ie7{
.cssname{
font-style: bold;
}
}
however when I write ie6 before ie7 (as in this example code), it
works properly for ie7:
@if user.agent ie6 ie7{
.cssname{
font-style: bold;
}
}
I was trying with other user.agent too like firefox, chrome... And it
only works with user.agent safari gecko1_8 but not for others. There
is no repported problem, so I don't know what's happened.
any idea?
Another cuestion:
to solve this problem I use a class that correctly detect the
user.agent of my browser and i use this code:
@if (com.banana.client.resources.css.CssAgentDetector.isIE6_7()){
.cssname{
font-style: bold;
}
}
but the code above doesn't work: the error says there are two
parenthesis which are expected to be closed. And i do a workaround:
@if (com.banana.client.resources.css.CssAgentDetector.isIE6_7())){
.cssname{
font-style: bold;
}
}
the extra parentheses is necesary to make it works properly, i dont
know why, the css parser is buggy?
thx in advice!

append the second module name?
neither of both of the following works:
1. java -cp gwt-dev.jar com.google.gwt.dev.Compiler
com.bla.foo.Module1 com.bla.bar.Module2
2. java -cp gwt-dev.jar com.google.gwt.dev.Compiler
{com.bla.foo.Module1,com.bla.bar.Module2}

And Yes we have GWT in production. That company's browser policy is to use
IE (now on 7, moving to 8). So this had to work or otherwise , it was a huge
showstopper!
GWT applications do perform (even in older browsers), just make sure that
critical parts of your code are carefully reviewed (especially on the
new).
AsyncCallback callback = new AsyncCallback() {
public void onSuccess(Void result) {
// do some UI stuff to show success
}
public void onFailure(Throwable caught) {
// do some UI stuff to show failure
}
};
// (3) Make the call...

RequestFactory error management
Hi all, the scenario is: - I have an ententy with its requestfatory, which manages correctly constraints violations. - I want also to catch an SQLException for a duplicate key and send an error message to the client. From documentation is specified that onFailure callback receives general failure notifications. So I tought that the solution could be to use onSuccess callback putting the entity inside a wrapper RequestResult object. But Requests can be parameterized with the following types: - Built-in value types: BigDecimal, BigInteger, Boolean, Byte, Enum, Character, Date, Double, Float, Integer, Long, Short, String, Void - Custom value types: any subclass of ValueProxy - Entity types: any subclass of EntityProxy - Collections: ListT or SetT, where T is one of the above value or entity types So my RequestResult should have a proxy interface which extends ValueProxy. At this point I lost some piece because it seems to be too complicated. Any ideas? -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: Performance Tip for IE browsers : Java garbage collection is NOT Javascript garbage Collection
Almost there...
method doSomething (){
callback c = createCallback();
}
static AsyncCallback? callback = null;
AsyncCallback? createCallBack(){
if (callback==null){
callback = new AsyncCallbackObject() {
// implement onSuccess
// implement onFailure
}
}
return callback;
}
Since we are keeping the callbacks stateless, this really improved
performance on IE!

Use JPA2 if you can, it has native support to enums. See Mapping simple
propertieshttp://docs.jboss.org/hibernate/annotations/3.5/reference/en/html/entity.html#entity-mapping-property
in
hibernate manual reference, the *Enumerated *annotation.

1) I have included a hyphen example in the files

3) Uibinder doesn't modify ClientBundle in any way. If the file

I've been playing around with this for a couple of days, to great
frustration. Can't get it to work.
I followed the example here:
http://code.google.com/p/google-web-toolkit/wiki/ClientBundle#Examples
That doesn't work either. The call to Window.Alert to print out the
css shows no text.
I also noticed a few other things.
1) I took to naming my styles with hyphens, just like in all the GWT
examples. Hyphens are not allowed.
2) The app won't start. An error message appears and the fix was to
add @external to the front of my styles. But WHY? Nothing I did
was any different from the GWT samples and none of them used
@external. So, I just did something for which I have no understanding
(the documentation is not helpful). I'd like to know, when is
@external not needed?
3) I am using uibinder and removed my css file from the war directory
and moved it someplace where the CssResource can access it (in the
class hierarchy). Now those styles are not being picked up. Probably
because the enjureInjected() isn't working. Or maybe ensureInjected()
doesn't work with uibinder. Haven't been able to get far enough to
determine.
I would like to see some decent documentation. It is nice to have
step by step just-do-it-this-way instructions. But when that doesn't
work, I have no idea why I am doing what I am doing. Seems like the
docs are written for those who already understand GWT, which kind of
defeats the purpose.

On Sep 8, 1:23 pm, Ernesto Oltra ernestoka...@gmail.com wrote:
Sorry, I meant if you use the CssResource to bundle your stylesheets
together with your app, it has a method ensureInjected(). The load
process
would be something like that:
Host page - GWT code - standard.css - Your code - Your CSS file
injected
So it's easier to overwrite styles in this way.
Sample code:
public interface Resources extends ClientBundle {
public static final Resources INSTANCE = GWT.create(Resources.class);
public interface Style extends CssResource {
String myCssClassHere();
String myCssClassHere2();
}
@ClientBundle.Source(Style.css)
@CssResource.NotStrict // If a class is present in the css file,
Style css(); //but not in the interface, don't

Re: Performance Tip for IE browsers : Java garbage collection is NOT Javascript garbage Collection
Interresting. But in this case, is not it the same problem for all anonymous
classes ?
Do not you have this problem with event handler ?
myButton.addClickHanler(new ClickHandler() {
public void onClick(ClickEvent e) {...}
}
2011/9/26 Rokesh Jankie rjan...@gmail.com
Almost there...
method doSomething (){
callback c = createCallback();
}
static AsyncCallback? callback = null;
AsyncCallback? createCallBack(){
if (callback==null){
callback = new AsyncCallbackObject() {
// implement onSuccess
// implement onFailure
}
}
return callback;
}
Since we are keeping the callbacks stateless, this really improved
performance on IE!

UiBinder
Hi fellas,
I have a ui.xml file:
!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
ui:style
.important {
font-weight: bold;
}
/ui:style
table
tr
tdTexto/td
tdImagem/td
/tr
tr
tdbutton ui:field=button //td
tdimg ui:field=image//td
/tr
/table
/ui:UiBinder
I'm trying to use HTMl instead of GWT components. I have this code on Java
class
@UiField
Button button;
String firstName = undefined;
@UiField
Image image;
public SampleBinderWidget(String firstName) {
initWidget(uiBinder.createAndBindUi(this));
button.setText(firstName);
this.firstName = firstName;
}
@UiHandler(button)
void onClick(ClickEvent e) {
Window.alert(Hello: +this.firstName);
image.setUrl(http://www.google.com/intl/en_ALL/images/logo.gif;);
}
When I run the code I get a error: Field 'button' does not have an
'addClickHandler' method associated, isn't the onClick() for that?
How do I fix this?
Thanks in advance for any help.

Re: Performance Tip for IE browsers : Java garbage collection is NOT Javascript garbage Collection
No definitely not: This is only with the callback Class (and in combination with a lot of data). Somehow the callback is not garbage collected properly in IE. The GWT team covered this part (of (new ClickHandler)...) See this link https://groups.google.com/forum/#!searchin/google-web-toolkit/clear$20memory$20IE7/google-web-toolkit/jPOhtj5vZT4/cOnK6MS_EQwJ And the last post of Joel Webber was definitely worth the read! So in short: Only the callback ( AsyncCallback()) class we changed to a static class variable and that was it...No other code changes... Again: java garbage collection is (apparently) NOT the same as Javascript garbage collection. -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Yet another obfuscation question, but related with Java Source Code Obfuscation
There are many topics about obfuscation, but they are about js obfuscation. I'm sure my question was asked before. But I didn't find. We have a java library which is closed source. With some effort, we modified the library as gwt-safe. The problem here is that this library should be closed source. I have tried the decompile the obfuscated code approach. But it fails. The remaining solution is to use java source code obfuscators? Is there anyone having same needs? Have you ever tried one of these java source code obfuscators? What are the results? -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group. To post to this group, send email to google-web-toolkit@googlegroups.com.

Re: Yet another obfuscation question, but related with Java Source Code Obfuscation
you could use the unobfuscated version of the project to create the javascript, then post javascript compile you could make sure sources are not included and your obfuscation scheme is implemented. You will probably want to implement a -noserver implementation to really get this going. -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

I updated to version 3.6.7 final version and it looks that the same
happens :(
Caused by: java.sql.BatchUpdateException: Batch entry 0 insert into
boundtype (type, name) values ('0', 'name') was aborted. Call
getNextException to see the cause.
I saw the cause and it is trying to insert integer 0... i think that if
some gwt library was making conflict with hibernate library it would send
an
error so i dont know why this happens...
2011/9/26 Juan Pablo Gardella gardellajuanpa...@gmail.com
Sure, hibernate 3.2.5 not support jpa2 :), yes you must update your
hibernate version, for example to 3.6.x. Version 4 I'm not sure if is
stable.
2011/9/26 Marko Borges markoborge...@gmail.com
Guess I have to update my Hibernate. I am using version 3.2.5 and
maybe need at least 3.5 to use JPA2.
Am I correct?
Thanks Juan, really!!!
2011/9/26 Juan Pablo Gardella gardellajuanpa...@gmail.com
What jpa providers (and version) are you use?
2011/9/26 Marko Borges markoborge...@gmail.com
Well, thanks...
I tried it and now says it tries to insert integer but i dont know
why:
public enum BoundType {
UPPER, LOWER, REF;
}
Im my class i have the attribute:
@Enumerated(EnumType.STRING)
public BoundType getType() {
return this.type;
}
and then i call it
Boundtype bt = new Boundtype(name, BoundType.UPPER);
hibernateTemplate.save(bt);
and says that i try to insert type as Integer ...
Thanks for trying to help me

Use JPA2 if you can, it has native support to enums. See Mapping
simple
propertieshttp://docs.jboss.org/hibernate/annotations/3.5/reference/en/html/entity.html#entity-mapping-property
in
hibernate manual reference, the *Enumerated *annotation.

Says that the column is of type XXX (my postgres enum) and I am
trying to insert varchar...
I know its an hibernate problem but i cant make some solutions
showed in web cause client side does not support UserType class, for
example.
I am trying to use Type annotation btw, and it doesnt work...

Hey everyone!
I am having a problem in persisting a postgres enum using
hibernate and GWT.
When i follow some instructions that i found around Web, it says
that client module does not support one class used to trick for
persistence.
Does anyone know how to do it?
Thanks,

RF/Backend Code not working after Compiling
Hi Everyone, Probably an easy fix but for some reason my project is not working properly after i have compiled it to my application server. Specifically, when i run the project in hosed mode my pages will pull data from a database using request factory and update the text on the screen, everything works great. After i compile and run the compiled code the text does not update on the screen.not sure if it's request factory not working or something else. I do not get any errors when running the compiled version. My code is compiled to a WebContent folder which is mapped in a Glassfish server running under Windows. Maybe there is a setting i need to tweak? Any help would be greatly appreciated. Cheers, -Mark -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

UIBinder, HTMLPanel, and style interactions
I'm noticing something weird. It is my first attempt at using HTMLPanel. The app is laid out with a DockLayoutPanel. The south panel is a footer panel and simply has a piece of text in it, which is always there. I want the text to be right justified with a bit of padding. g:HTMLPanel width=100% height=100% styleName=my-footer-panel- style div ui:msgSome Text Here/ui:msg /div /g:HTMLPanel The style, my-footer-panel, has a font, color, and padding. The padding doesn't appear to work. When I look at the page in Firebug I seem some strange things (see below). The style is in there (as a class), but the style attribute looks to be overriding the class with some inline styles. div style=position: absolute; overflow: hidden; left: 0px; right: 0px; bottom: 0px; height: 24px; div class=my-footer-panel-style style=height: 100%; width: 100%; position: absolute; left: 0px; top: 0px; right: 0px; bottom: 0px; divSome Text Here/div /div /div Why does the DIV have both a class and a style?

Re: too much code: GWT Development with Activities and Places
I am personally happy with a strong gwt core, and that just keep getting better with each release. I couldn't agree more Gal. It is the bugs in the GWT core that I feel need to be strongly prioritized. That is where any development resources that Google assigns to GWT are most profitably deployed. My worry is that I see those valuable resources being applied to new high level architectural concepts which may or may not be useful to users, while nasty reported bugs remain for months or even years in the core functionality.

Deferred locale selection/re-selection?
Hi, I need to write a multi-locale app that allows the user to change their locale at runtime. I would like to design the app so that I get the maximum benefits of GWT's deferred binding functionality with respect to locale. I must allow the user to log in to the app in one locale (say de-DE), and then later allow them to switch their locale setting to something else (say es-ES) without logging out. Ideally I would initially only load code and localization resources for the de-DE locale, and for most users that would be sufficient. Other users may wish to spontaneously change their locale, and at that point I would like to only load the code and localization resources for the new locale (es- ES or whatever). My problem is that the nocache.js script does its locale-specific code- swapping magic at boot time, and I would like to put that off until a bit later in the app. Can anyone recommend a strategy for achieving this design?

Though reading through the User Guide, you could be forgiven for thinking 'This is the way I should go with my app!', especially if you decide to use UiBinder, as the Activity/Places MVP article uses it and is almost like a tutorial on building an app. I guess its just because the other tutorial in the User Guide, the Stock Watcher, doesn't use UiBinder, which is a very attractive feature to anyone new to GWT.

Re: Isn't the Activities and Places model violating the MVP pattern?
Thanks for the response. I shall have a look at those links later tonight. If you value theory and purity more than pragmatism and productivity, then yes, it probably violates the pattern, as it doesn't use the observer pattern. My concern is not that passing the presenter to the view is a bad thing per se, but that when doing so we can not say we have implemented the MVP pattern anymore, as in each design pattern the collaborators, their responsibilities, and the relationships between them are set in stone so that when I say that Foo is Singleton it is universally clear what Foo is. In other words, design patterns make it possible to communicate ideas clearly as long as they have a clear and universal definition. So maybe we should call this design pattern something else. However looks like there's not a clear definition of MVP available anyway, as for example in Dolphin Smalltalk it means something different to ASP.NET. Now back to passing the Presenter to the View, what methods of the presenter should be exposed to the view? Should the view still be ignorant about the model? or should we expose PresenterImpl.getContacts(): ArrayListContact to the view as well? -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Permutation, code splitting and deferred property
Hi,
I got an issue with deferred property and code splitting.
In my GWT configuration file, I have defined the following property:
define-property name=myProperty values=value1,value2 /
set-property name=myProperty value=value1
when-property-is name=user.agent value=gecko1_8 /
/set-property
set-property name=myProperty value=value1
none
when-property-is name=user.agent value=gecko1_8 /
/none
/set-property
and I have a generator with the following code that generates one
implementation depending on this deferred property value:
public String generate( TreeLogger logger, GeneratorContext context,
String typeName ) throws UnableToCompleteException {
String value = propertyOracle.getSelectionProperty( logger,
myProperty );
if(value1.equals(value)){
return generateImpl1();
} else {
return generateImpl2();
}
}
According to my settings for each browser, you can have only one
value, ie for each permutation my generator should generate either
Impl1 or Impl2 but not both. However in my soyc report, I noticed that
for each browser/permutation, both implementations are generated.
The issue I have is that my generator generates the same GWT.runAsync
call for both implementation and since the 2 implementations are
generated for each permutation (even if only one can be used for each
permutation), GWT believes there are 2 split points and since it's the
same code inside the 2 split points, all the code is added to the left
fragment code.
My question is how come my generator is called twice for each
permutation? Since only one value is possible for each permutation
shouldn't it be called only once? Am I doing something wrong in my
configuration which could explain why my generator is called twice?
Thanks for your help,
Pierre

I have another approach to try - I may replace all RPC code with a Command executor and restrict access to it behind a runAsync() so all RPC code is in the single split point (and thus not in the left overs) The problem with using RPC directly is that the actual plumbing code is auto-generated so I can't restrict its access to behind a split point. Would this work: create all RPC services in a factory class that can only be instantiated behind a runAsync().
