Re: IE 8 and status code error 12030 - 12152

[Craig Mitchell]

I get this error in IE if I loose connection to the server during a RPC. 
 So, for me, 12031 ERROR_INTERNET_CONNECTION_RESET, is an somewhat accurate 
description (sort of).

Re: Eclipse Analyzing Sources Slow

[gutto]

Over the weekend my build times have reduced! Perhaps we were having
some network issues which were exacerbating the problem. However, it's
still slow. I have tracked the cause down to repeated requests for the
DTD document http://dl.google.com/gwt/DTD/xhtml.ent that is referenced
by each UI Binder templates. I have 80 XML template files and the DTD
doc is request 178 times during a clean build. The workaround I have
found is to download and store this document locally and add it to the
Eclipse XML Catalog. Doing this reduces my build time from approx. two
minutes to under 15 seconds.

Wouldn't it be sufficient to fetch such things once per build?

Would be interesting to know if the previous GPE and Helios request
this DTD so many times. (I used Wireshark to watch what was going on.)

No source code is available for type com.google.gwt.autobean.shared.AutoBean

[amos]

Hi,
I'm trying to use AutoBean to serialize and deserialize JSON. The
application is failing with the error "No source code is available for
type com.google.gwt.autobean.shared.AutoBean".

Do I need to add some includes or some other configuration in order to
use AutoBean?

Thanks,
Amos

Re: How can I get the "Expenses" sample up and running?

[Warren Tang]

Hi David,

I'm really thankful for your patience for answering this starter's 
question. 

I imported the project into eclipse from according to the readme file. Maven 
had an issue finding the gwt-servlet2.2.jar. I fixed it by changing the GWT 
version to 2.3.0 in pom.xml, and adding GWT SDK and Appengine SDK to the 
classpath. The project was then built successfully. But when I run it in the 
dev mode, the following error appears in eclipse's console view:

Exception in thread "main" java.lang.NoSuchMethodError: 
org.mortbay.thread.Timeout.(Ljava/lang/Object;)V

I've no idea what it means. 

Besides, it should need my appengine credentials in order to fill data into 
appengine, right? How can I configure it?

Re: my biggest problem with gwt

GWT RPC has been particularly offensive when it comes to being slow in

massive improvement in Chrome performance.

Alex, But if your widgets are to be inserted at runtime what you

Re: GWT frameworks?

[Tomasz Gawel]

still nobody mentioned gwt-query - which btw is truely a framework.
while i dont like it's jquery-like naming convention - i stay
impressed with the code itself, especially selector engine ;).
as to gxt and smart gwt - it was not sth i was looking for so i
abandoned using it.

gwt itself is a framework - and while i am not fully convinced to it's
swing-like widget/panel architecture (and gxt or smart gwt made it
even worse), i got used to it.
what i found really missing in gwt was selector engine. moreover, it's
fast growing framework, and thus leaving less area for frameworks.

pure javascript frameworks in much level originated from a necessity
to cover browser differences, and its it's not the case with gwt.

spurious blur event after update to 2.3

[bhomass]

I used the CellEditor.startEdit() feature on a tab header. after
upgrade to GWT 2.3, I am getting unexplained blur events which
continuous stops editing. for example, right after I start edit mode
(by double clicking the header), there is a blur event. I used the
code to ignore that. then after every key stroke, another blur event,
there are others whose origin is not at all clear.

Any one knows what could be causing this and how to prevent it?

The former.

I was looking around in the repository, but didn't see it (them). But I
have to admit I didn't spend more than 5 minutes searching.

Anyway, the maintenance of the FF plugins has exigent nature that isn't
shared by most of the GWT baseline. Can the "relaxed" nature of most
Open Source development work with such a time-constraint? That's why I'm
suggesting a discussion about this topic.

It's not clear yet what'll be required.  It looks like whoever wrote
the current plugin did a pretty decent job of separating concerns.
I'm currently playing with one of the WebKit example NPAPI plugins
(from webkit.org)... and that at least works.

I would like to say that it really stinks that nobody from the GWT
team warned us that Safari 5.1 + OOPHM doesn't work.  It's debatable
whether or not it's my responsibility to keep up with this stuff, but
it's definitely the GWT team's responsibility to at least communicate
such things to their users.

Part of me wants to say f*ck it and use FF, but frankly, I don't like
FF.  Devmode is painfully slow in Chrome, and I'm definitely not
switching to Windows.

Re: GWT Developer Plugin on Safari 5.1 (OS X Lion 10.7) doesn't load

Sure, do you mean the GWT community or some other? Dev mode plugins
are open source, so if someone has interest in keeping them up to
date, we're all ears...

Re: RequestFactory create proxy object serverside

[Ryan McFall]

I don't think this will work, nor do I think it should.  As far as I
understand it, when you send a proxy reference via a Request, the RF
framework attempts to find the server-side entity the proxy is
referencing (using the ID), and then calls the associated method in
your service implementation passing the server-side entity to the
requested method.  Since your object does not exist on the server if
looked up by ID, the call should fail.

If you want this to work, you need to actually persist the object in
createByBarId.

Why do you want to do this?  I've wanted to do it in order to get
default values set on the client-side proxy, but not have the object
persisted.  Unfortunately that's not possible.

Re: GWT Developer Plugin on Safari 5.1 (OS X Lion 10.7) doesn't load

[David Chandler]

Good luck, Eric :-) It likely requires non-trivial changes (which is
why the GWT team hasn't done it yet).

We're currently evaluating how to handle the recent Firefox as well as
Safari changes going forward. The FF change is especially onerous as
it now requires engineering effort every 6 weeks to stay up to date.

Re: Making the Slider Bar included in the Google Web Toolkit Incubator Vertical

[darkflame]

This would be very nice, but I think impossible with the current
implementation.

You could try this one;
http://code.google.com/p/gwt-slider-bar/
But that gave me problems when I used it.

Really GWT needs its own native slider class, seeing as Incubator is
depricated.

After using Context menu, how to trigger the browsers default one? (on, say, an image)

[darkflame]

I was using this bit of code I found to detect a right click action on
a widget;


@Override
 public void onContextMenu(ContextMenuEvent event) {
 event.stopPropagation(); //This will stop the event from being
propagated to parent elements.
 event.preventDefault(); // because cancelBubble(Boolean) is
deprecated
 Window.alert(“replace this line with your popup function “);
 }

The widget implementing "ContextMenuHandler".
This works, only I'd like to only trigger it sometimes, and at others
leave the browsers normal context menu to appear.
I thought this would be as easy as putting the whole thing in a IF
statement;

@Override
public void onContextMenu(ContextMenuEvent event) {

Log.info("context menu event triggered");

//override the menu only in edit mode
if (panelstreamer.EDITMODE){
 event.stopPropagation(); //This will stop the event from being
propagated to parent elements.
 event.preventDefault(); // because cancelBubble(Boolean) is
deprecated
 Window.alert("replace this line with your popup function ");

} else {
Log.info("_context menu event triggered but no 
edit mode");
}
}

But this doesnt actualy seem to work - the second Log file displays,
but the normal right click context menu still doesnt pop up.

Do I have to specificly tell the browser too?
(even though the stopPropation and preventDefault arnt being
triggered).


Thanks for any help,
Thomas

Re: GWT Developer Plugin on Safari 5.1 (OS X Lion 10.7) doesn't load

[Eric Ridge]

So I just found the page on developer.apple.com that definitively says
the WebKit plugin API is no longer supported as of 10.7 (which I
assume also means Safari 5.1, regardless of OS version):

http://developer.apple.com/library/mac/#documentation/InternetWeb/Conceptual/WebKit_PluginProgTopic/WebKitPluginTopics.html

It says:

Note: As of Mac OS X v10.7, the legacy WebKit plug-in architecture is
no longer supported. Going forward, you must convert WebKit plug-ins
to Netscape-style plug-ins or Safari Extensions.

So now that I know what's going on for sure (and have documentation
reference), I'm going to attempt to convert the plugin.  Wish me luck.

URGENT: navigation bar menu

Hey guys.

I need one menu where user doesnt need to click to see the menu items.
I didnt find anything for it, so I tried with MenuButtons and insert a
Menu with items in it, and then add two events: MouseMove and
MouseOut.

But it doesnt work well and I think its because of the animation
coding for Menu, like: menu.animateShow(AnimationEffect.FADE);

Can anybody help me please!

of custom widgets.  For frameworks any of them libraries can use different
frameworks.

Re: GWT + Javascript Libraries

[KD]

It totally makes sense to use other libraries (with JSNI approach) to
do something that GWT does not offer out of the box (yet i.e.)
The problem is making a wrapper that is agnostic to the JS library
version and making sure you are not writing your own (pure or not)
javascript that is not cross-browser OK.

Yes, it only caches the data on the current page.  When you go back and
forth between pages (even pages that you've already visited), CellTable will
send a new request to the data store for the rows in range.

This allows you to control the overall caching policy in your data provider.
 You can choose to cache all rows that you receive from the server in your
data provider, or you could, for example, just cache a window for plus or
minus 5 pages.

Re: Cell Table Data Handling & Performance

[BST]

Many Thanks for the input. 

The scenario is that I am not displaying more than 100 rows per page. And 
the pager works through 3 pages. 

Yes the Data load is on Demand, as when the user presses the next button for 
the 4th page I am getting another 300 rows thru an RPC. It is a plain view 
only table. So only after the user has paged thru the 3 pages I go for the 
next batch of 300.

 Also No changes or search within the table, it is view only. The table is a 
result of a server call for search. So I guess so far no worries :-)


CellTable caches the row values within the current page so it can pass the

My understanding: So when I am viewing the 11 th page with 100 rows and go 
to the 12th page  (using an implementation AbstractPager), the rows on the 
11th Page is dumped and no longer in the browser. So only 100 rows are 
managed by the browser even though 1100 rows of data is available with the 
DataProvider List. Have I got it right?

Let's say the User has paged thru about 12 pages, so there is a list of 1200 
in the dataProvider list already of which 100 are being shown in a page. So 
when the user goes back and forth within the range of 12 pages(1200 rows) 
sorting or changing the display per page  to be 50 or 25 (on the client 
side),will the cell table efficiently manage? 

I guess after your reply I will be more confident in delivering the solution 
:-)

Re: GWT frameworks?

[joe kolba]

depends on what you are going to be using your application for... If it's
something within a company and possibly served from a local server I highly
recommend smartgwt.  Something that is going to get a lot of traffic and
needs to be fast and responsive i would just stick with original GWT with
gwt mvc.

Is there no more new big frameworks for gwt?

Smart GWT, GXT, and Vaaldin?



I like gxt the best when I tried it before because of speed and widget
options.

Smart GWT was slow for me I not sure if they improved that.

The maximum page size is heavily dependent on the app and the data being
displayed, but some teams have gotten into the 250-500 rows per page.
 Assuming your backend can provide the data quickly, the limiting
performance factor of CellTable is rendering, and rendering a 500 row table
isn't instantaneous.

All modern browsers should be able to handle an array of a few thousand
Contact objects without a problem, but if you are searching through the
array, that might be slow.  You also have to consider bandwidth constraints.
 Can you load the Contacts on demand and push the processing to the server?

There is no performance lag in CellTable itself.  If your backend can
provide data within a range, paging is a better experience than loading
10,000 objects upfront.

CellTable caches the row values within the current page so it can pass the
row values to Cells, and so it can re-render rows when needed.  When you
switch pages, the row values of the previous page are dumped.

We give permissions,

1. SharePoint groups with individual users

2. SharePoint groups with AD groups

3. SharePoing groups with AD groups and Indivdual users

4. For some site which have unique permissions individual users are
given permissions directly.

The two options would be to use GWT

SharePoint Permissions Issue - Users moved from Domain A to Domain B

[Srilakshmi Chilukuri]

We have an Windows Server 2003 AD DS forest, under which we have two
domains trusted
Domain A and Domain B

We are moving users from Domain A to Domain B

We have  MOSS 2007 intranet and internet SharePoint site which have
several site collections with sites ranging from 10-500 in each site
collection.
Till now the users were given permissions using DomainA\userid to all
these sites.

After the users are moved to the new domain, I have to give
permissions to the individual users once again by adding them to the
sites using  the DomainB\userid account.
We have 5000+ users what is the best way to replace or change the
users permissions to use the  DomainB\Userid accounts.

Are there any tools available for doing this?

{
Request createByBarId(String barId);//create new Foo object 
(dose not persist it)
Request calculate(FooProxy foo);
} 

createByBarId works fine but when I call calculate I get: Server Error: The 
requested entity is not available on the server.

I think I understand the reason for this error. But is there any way to tell 
RequestFactory that this object has not been persisted jet and force it to 
send the whole object, not just the diff? Just as if it had been created 
using requestContext.create(FooProxy.class) .

The Expenses sample is designed to be used with Maven. See

Re: GWT animation and effect library with CSS3 support

I added some documentation and code example. I am not sure what is

Please tell me if you need anything more. Perhaps some more sexy demo?

= I can use some help editing the doc =

As you can tell my english isn't perfect so if some kind native

Re: GWT MAVEN PLUGIN Loading Images

[David Chandler]

In a Maven project, images and other Web artifacts (html, css) belong
under src/main/webapp. If you're using GWT's image bundling (see
ClientBundle in docs), the images will go in src/main/resources
instead.

Please post any follow-up questions specific to gwt-maven-plugin to
the appropriate mailing list.

SimpleEventBus : why such a non-predictive behavior implementation ?

[david.herv...@gmail.com]

Hi,

I'm facing a problem when using the simple implementation of the
EventBus.

// register widget B to be notified when WidgetA trigger an event
register handler of WidgetB on WidgetA.EventType

// dispatch (firingDepth is incremented)
WidgetA.fireEvent

// my widget is really called !!! that's good news
WidgetB.onWidgetAEvent

// on the WidgetA.EventType reception is decided to create a widget C
create widgetC

// this widget register himself to be notified on widgetB events ->
here the widget is registered in the deferredDeltas map (enqueueing)
register handler of widgetC on WidgetB.EventType

// widget B fired an event which is never trapped by the widget C
because the handler of Widget C is in the deferredDeltas AND
firingDepth is not 0
WidgetB.fireEvent

I'm doubtful because I was expected Widget C to receive event from
Widget B. A work around is to encapsulate the WidgetB.fireEvent into a
DeferredCommand but it's not really a solution.

An other solution is to reconsider the usage of firingDepth, I don't
really know why it is used (actually I know, but avoid concurrency
modification that way leads to the upper that strange behavior).
In simple implementation (thread safe) will be to get rid of the usage
of this firingDepth/deferredDeltas and that getHandlerList return a
copy of the handlers to go through and that's it:
We insert directly the handler when they request for registration and
we fire on the current map of handlers

Below is a possible implementation of what I think is a better
implementation (behaviorally speaking) :

GWT MAVEN PLUGIN Loading Images

[vzm]

Hi guys

Could you please tell me where is the best folder to put photos??

I am a beginner en gwt with maven, but I worked with both separately.

I am trying to build a project with GWT MAVEN MYBATIS SPRING. So
difficult for the third time??

The question is... where could I put the images folder? What do I have
to do to build this folder? Or Maven recognise it

I'll put it in WEB-INF folder but maven doesn't propagate it, or, I
did it so bad...

Could you please help me?

Thank you

Cell Table Data Handling & Performance

[BST]

Hi,

I have successfully managed to use a Cell table & an abstract pager to
fetch the new set of data from an RPC and display them on the cell
table. Many thanks to the developer discussions and Developer Guide.

But I do have a few concerns, as I plan to use it for large data sets,
maybe like 10k objects. The Developer Guide does mention Cell table
can handle large data sets, but I wanna know how large is large, any
approximate number of objects in a list? Also a few other questions
below,


Will my browser performance become sluggish if I load too many objects
simultaneously ? For E.g lets say I store a list of Contact objects,
with a pic of the contact and other textual information such as name,
address and mail. The image might be a blob or a Base64 string.

Is there a performance lag while using the pager on a really large
data set?

If you are not sure, maybe you can tell me this, how the object
handling in a list w.r.t Cell Table is done , and do the objects exist
once objects are converted to html in the Cell Table on the client
Side?

Regards,
BST

i18n, properties and SafteHtml

[Johannes]

Hello,

I'am using the I18NSync to generate Messages interfaces from
properties file. I've read in the documentation that Messages support
SafeHtml. Is it possible with the I18N-tools to generate safehtml
Messages?

I had a look at AbstractLocalizableInterfaceCreator. Am I right that
only the type String is supported?

Multiple dialog boxes

[Ric -]

Hi,
i have a problem with the dialog boxes from the gwt. It is no problem
to use one dialog box,
but i need multiple of them. If one dialog box pops up, the other one
gets locked and you can use the first dialog box until you close the
new one. Is there a way to solve this problem ? For example a
parameter which deactivate this "locking feature" ?

Re: Frustrated with GWT

[JC]

I spent one week trying to connect my GWT Client application to my
Servlet throug RPC and I got a similar problem.
I gave up testing from Eclipse/GWT plugin against my servlet handling
the JDBC connection. It looks like GWT is forcing you to use Jetty and
GWT database.

I solved the problem with the following solution:
I created a Java package (.jar) to handle all JDBC statements only.
The Servlet invokes the classes in that .jar files.
I deployed the Servlet and the package in Tomcat
I wrote a JSP to test the Servlet. It works great.
I generated a jar file with my GWT Client application which implements
RPC to call the Servlet.
I deployed the GWT Client application in Tomcat.
I tested the whole thing successfully.
You can spent about one hours splitting your application in three
pieces, but it'll work.
After that I'm very happy using GWT just for UI.

I hope this can help you.

Greetings,

JC

Re: Regarding menu navigation (page to page) in GWT

[Justin T]

Here's what I usually do to transition between "pages" in GWT. It may or may
not be what your looking for.

I first clear the Rootpanel, then add to the panel another class which acts
like another page.

Here's a example:

public class Example implements EntryPoint {
  public void onModuleLoad() {
  final Button nextButton = new Button("Go to another page");
  //Activates if the button is clicked.
nextButton.addClickHandler(new ClickHandler() {
public void onClick(ClickEvent event) {
  RootPanel.get().clear();
  RootPanel.get().add((IsWidget) new Page());
}
});
  }
}

public class Page{
public Page(){
//Heres your new page. Anything you add to the RootPanel will show
up on the screen.
   //In your case you will probably want to re-add the menu here first.
 }

}

I've got your example working... kind of, thanks. But I still can't

Re: How to package a gwt project into a jar so that it can be included into other projects

[Nandha]

Hi..

I ll explain upto my knolege

You can use the server side classes directly but not the client..
The server side classes you can find out from
projectname\war\web-inf\classes folder in your workplace of eclipse

Client side Code:
These code are complied as html and java scripts You cannot use it
externally ..
In this you should resuse the client side classes in the editor itself with
the source code by copying your old project package into the new project
packages

Re: Frustrated with GWT

[Kevin Jordan]

Yeah, definitely looks like a case-sensitive error.  It's got
uppercase letters in the mapping of where it's listening on, but all
lowercase in the request.

Regarding menu navigation (page to page) in GWT

[Nandha]

Hi,
Requirement : More pages . navigation using menu

am using menu for navigating from a page to page..
In this I created a rootpanel with a content panel .
i added  two pages inside the content panel.. one with visible and
another with hidden..
On click of the menu both are interchanging by show() and hide()
functions...
but the sub components are not showing with the proper height and
width
Doubt is : Is the correct way for creating more pages with menu..

or is there any way for creating more pages in a single GWT project
..
Note : In my project there is only one html file and only one
entrypoint

Is there any other way...

Am feeling we can make more html files..
Can anyone help me for that and guide me a way to work with menu for
navigation

Yes, you're right. It's a mistake. I copied your method signature and
forgot to remove void after adding FocusPanel as a return type.

Re: Declare an array of panels in UiBinder

[Tomasz Gawel]

Sorry i haven't noticed vp is panel not list ;)
so in java you have sth like that:

List slots;
@UiField FlowPanel slotTargetPanel;

@UiFactory FocusPanel void addSlot() {
   FocusPanel slot = new FocusPanel();
   slots.add(slot);
   return slot;
}

in ui.xml:




Some sample html ...








Some sample widget




in fact slotTargetPanel is not needed for that - you could stick
Focuspanels anywhere in your ui file - as you have an uifactory method
for creatign FlowPanels.

Re: Declare an array of panels in UiBinder

[Tomasz Gawel]

Assuming you do not use FocusPanel in other cases in this Widget just
anototate addSlot with @UiFactory and return newly created slot from
it:

@UiFactory FocusPanel void addSlot() {
final FocusPanel fp = new FocusPanel();
vp.add(fp);
return fp;
}


this will cause uibinder to call this method instead of FocusPanel's
constructor.

Re: Changed handling of quotes in GWT localizable resources?

[googelybear]

just found out that this only affects properties loaded via the
Constants interface. When using  in uibinder files the old
trick still works (I guess this goes via MessageFormat). But when
loading the property programmatically using Constants interface it
does NOT work (meinaing 2 '' in the source file will also be outputted
as 2 '').

Re: Changed handling of quotes in GWT localizable resources?

[googelybear]

Hi,

I am a bit puzzled about this, is no one else facing this issue? How
did you guys solve it?

According to the official Message Format javadoc from Oracle (http://
download.oracle.com/javase/6/docs/api/java/text/MessageFormat.html)
the old trick with doubling the quotes should still work (quote):
"Within a String, "''" represents a single quote. "

but when I write the following property in my properties file:
"foo = you can''t do this"

the output will be "you can''t do this" - with 2 single quotes still
present - instead of one according to the javadoc.

Is this a gwt bug?

thanks for any feedback,
Dennis

Declare an array of panels in UiBinder

[Alexander Orlov]

Currently I do

@UiField
VerticalPanel vp;

void addSlot() {
final FocusPanel fp = new FocusPanel();
vp.add(fp);
}

...so, vp contains a variable number of fps at runtime. However I try
to use UiBinder wherever it's possible.

Is it possible to declare Widget Arrays resp. ArrayLists in UiBinder
that might have a different size at runtime and (if not) are there
plans to implement it?

Re: Aw: Re: MVP best practices, how to expose a view to a presenter?

[Thomas Broyer]

You'd have to either juggle with binding annotations (and possibly private 
modules), or have the same dependencies in your provider as in your provided 
class (to be able to 'new' the class yourself in the provider) and keep them 
in sync.
IMO, unless you're in a hurry, if this is absolutely necessary (i.e. you 
cannot live with either a singleton or the default behavior) then you'd 
better contribute the support for custom scopes to GIN.

Re: Battery Percentage

[Ashwin Desikan]

have two images one for battery red and battery green. you can define 
them as sprites in your CSS under different style names like batteryRed, 
BatteryGreen. Your logic can fire an event when the battery% has reached 
above or below 40% and accordingly change the image by applying the 
appropriate style (Red or green)
