True - I wonder if there is another solution. Like a special
GWTRuntimeException you can extend into your own exceptions, so GWT
knows only to generate javascript code for them ?

How does that sound ?

Its a feature, not a defect.

You have to *explicitly* declare any methods you want to send to the client.
Without this declaration, GWT would have had to create javascript code for
every RuntimeException in the system - and that would certainly lead to code
bloat.

My problem lies in RPC.java line
377; !RPCServletUtils.isExpectedException(serviceMethod, cause))

The function RPCServletUtils.isExpectedException does not take this into
consideration;

--> if the cause is an unchecked exception
--> if the cuase is an subclass instance of an defined and checked exception

The workaround seems to be to define the explicit exceptions throws in the
service interface.

Does anyone have a reason for why I should not report this a bug in the
issue tracker ?

Re: GWT 2.1M3 Expenses

2010-09-15 Thread Rud

Thomas,

Thanks, that let me make some headway but not there yet. My web.xml
now has:


   requestFactory
   com.google.gwt.requestfactory.server.RequestFactoryServlet
  
userInfoClass
us.k5rud.scaffold.server.GaeUserInformation
  


and it is finding the GaeUser... class because if I munge its name it
gives me a not found error.

What I have now is a 500 error retured with a JSON Exception about not
finding the class definition. The class RequestFactoryServlet is at
line 82:

RequestProcessor requestProcessor = new
JsonRequestProcessor();

Any ideas?

Appreciate the help...

Re: GWT Spring integration - what is the best method in late 2010?

2010-09-15 Thread lalit

Deepak - I have used the following structure
   SpringApplicationContext, SpringGwtRemoteServiceServlet ,
PersonServiceImpl go into the server side code.
  The interfaces PersonService and PersonServiceAsync  become part of
GWT client side code.

Regarding wsdl files consumption see the section on JAX-WS here
http://www.lalitbhatt.com/tiki-index.php?page=JAX-WS especiall JAX-WS
client side section. This approach uses JAX-WS approach.

For data binding you can use JAXB. The details can be seen here
http://www.lalitbhatt.com/tiki-index.php?page=JAXB. JAX-WS anyway uses
it internally.

Also just a disclaimer, the approach I took is as per Spring4GWT
project so it's there idea.

Jason- I looked into your approach and conceptually they look similar
in terms of that you are redirecting the request to Spring MVC
infrastructure. IMHO the aprroach I took as per Sping4GWT is better as
one does not have to carry the SpringMVC baggage.

Otherwise ignore this.

Uninstall Google plugin from Eclipse

Hi

After I uninstall Google App Engine Java SDK 1.3.7 from Eclipse with the
following steps:
Help -> About Eclipse -> Installation Details -> Google App Engine Java SDK
1.3.7 -> Uninstall

I can still see the SDK listed here, Window -> Preferences -> Google -> App
Engine
I think this entry should be removed too?

the event fires, but if I have any code immediately after, that code
does NOT get executed.

For example if I have

Window.alert( "here" );
ChangeEvent.fireNativeEvent( Document.get().createChangeEvent(),
myListBox );
Window.alert( "there" );

I get "here" but not "there".

So when you fire your event, could you please do the same thing (put
in a Window.alert or other code to see if it is executed AFTER the
event firing is called)?

FYI: I've logged the whole sordid story here

Re: GWT Hosted Mode Slow

2010-09-15 Thread Chris Conroy

We're working on making it faster.

If you'd like to find out where it's spending its time (and perhaps provide
us another useful data point): update to trunk and add
-Dgwt.speedtracerlog="/path/to/myproject-speedtracer.html" to your JVM
arguments. Launch your app, maybe do a refresh or two. Install the Speed
Tracer Chrome 
Extension
(and give it access to local file URIs in chrome://extensions). Open the
resulting trace file in chrome, click "Open Monitor" and check out the
visualization. You'll want to expand the initial timeline view. The most
interesting data is going to be the summary pie chart you get from clicking
on the Module Init row. Feel free to share screenshots of those summary pie
charts in this thread.

No, the plugin works OK with -noserver; but it is only "triggered" if
you have a ?gwt.codesvr= in the URL. If you pass -startUrl 
http://myserver/foo.html
to DevMode, it'll ask you to copy/paste the modified URL into your
browser (or directly launch the browser if possible)

The servlet is simply
com.google.gwt.requestfactory.server.RequestFactoryServlet; contrary
to GWT-RPC it works by reflection over the classes (the Record class
name --or is it the request class name?-- is sent over the wire,
loaded from classpath, server-side class extracted from the annotation
on the class)

GWT 2.1M3 Expenses

2010-09-15 Thread Rud

I got the Expenses example from the repository. I stipped it down to
just the Scaffold portiong to try understanding the new architecture.
I got it running so it would put up the web page but with, obviously,
no support for actions.

Around line 80 of Scaffold.jave I enabled the line which requests user
information. It stopped working so I split the line into:

UserInformationRequest uir =
requestFactory.userInformationRequest();
String href = Location.getHref();
RecordRequest  rr =
uir.getCurrentUserInformation(href);
rr.fire(receiver);

They all execute but at the call to 'fire' it dies with an error that
the "gwtRequest" cannot be found. This is a servlet request but I
cannot find a servlet in the code. The GaeUserInformation class would
appear to be what is needed but it isn't a servlet. Nothing else in a
'server' direcotry references user information.

Is there something new in the way of getting user information under
2.1M3 or AppEngine 1.3.6?

Any suggestions on how to proceed? This shouldn't be critical since it
isn't part of the new architecture but frustrating not to understand
what is a happening.

Manual Serialization

I'm trying to use the built-in functions of GWT to serialize something

RPC.streamResponseForSuccess to write it to a ByteArrayOutputStream.
However, I get an exception part way through serialization:

GWT Hosted Mode Slow

2010-09-15 Thread Niels

I have a bit of a problem with GWT Hosted mode taking an awful long
time to launch my app - even just reloading the page (with the server
running and no code changes) takes forever.

The CPU is at 100% for a couple of minutes and as far as I can tell
none of my code executes (it's deep in the belly of some GWT code).
The few times I've managed to hit pause in the debugger, the offending
thread shows the stack trace below (the finer details may vary, but
it's always in getRootPanel):

My HTML is dead simple - a single table with two cells, so it's not
like there is a million IDs to look up, and I only call getRootPanel
once at the very beginning. I have never had this issue with other GWT
projects I've worked on, and can't for the life of me figure out
what's different this time (in fact I have another entry point in the
same project that works just fine).

Anyone have any ideas?

Re: GWT with Hibernate - Gilead vs. Beanlib

2010-09-15 Thread kjordan

Only reason I can think of to use Gilead is if you want to send an
object across the wire, update it, and send it back.  Using its
various state stuff it's able to turn it into a detached entity which
can be merged in.

DockLayoutPanel inside a TabLayoutPanel

2010-09-15 Thread Per

We are trying to insert a Component that uses a DockLayoutPanel into
one of our Tabs of a TabLayoutPanel. It seems as if the
DockLayoutPanel simply ignores where it is put into and lies over the
TabLayoutPanel. Its "north" is acually above the TabBar, on a
different layer or so.

Is this simply not possible, or is there a trick to it?

Best Regards

Per

Why does GWT seem to ignore my overridden doGetSerializationPolicy()?

2010-09-15 Thread theosophe74

Gilead 1.3.2's PersistentRemoteService, which extends GWT's
RemoteServiceServlet, has a protected doGetSerializationPolicy() that
calls super.doGetSerializationPolicy().

My own CustomPersistentRemoteService, which extends
PersistentRemoteService, is being created so I can deal with conflicts
between GWT RPC and Apache mod_rewrite by tweaking the moduleBaseURL
parameter [1].  This custom class also has a protected
doGetSerializationPolicy() that calls super.doGetSerializationPolicy()
after it just echoes out for now the parameters it is passed (I'm
logging them at the WARN level so I can see them).

So if I update a service implementation to extend
CustomPersistentRemoteService instead of PersistentRemoteService,
shouldn't I see the logging statements I inserted echoed to my
configured Log4j appender (in this case, the console)?

What is it about the following stack trace that just seems to skip
over both PersistentRemoteService and CustomPersistentRemoteService?

IE 9 Beta exception in IE9Standards mode on button creation

2010-09-15 Thread Brian

Just downloaded the IE9 beta, and ran my site through it, but I'm
getting exceptions.  They only occur in "Document Mode: IE9 Standards"
-- everything seems to work in the other Document Modes (IE8
Standards, etc).

The easiest way to see an exception is having a button made in a
UIBuilder class.  The pretty javascript is:

function com_google_gwt_user_client_ui_Button_Button__V(){
// Exception here:
  this.com_google_gwt_user_client_ui_UIObject_element =
$doc.createElement($intern_295);
  this.com_google_gwt_user_client_ui_UIObject_element[$intern_296] =
$intern_297;
}

Maybe I don't have something set right on this IE9 beta... ?

HTML Widget and Firefox

2010-09-15 Thread Nestor

I have a need to provide a TextArea in my application for a user to
enter text, but the text needs to be converted to HTML format when
using it. For example, I need the following text "foo\n\nbar" to
convert to "foobar".

The solution I've implemented is to use a HTML widget as an
intermediary, using the following code:

  TextArea textArea;
  HTML translator;

  ...

  translator.setText(textArea.getText().trim());
  String htmlString = translator.getHTML();

The code works fine on IE, but totally fails to do the conversion in
Firefox.

Help?

For the record, I'm using GWT 1.7.1 running in both IE8 and FF 3.

Re: GWT Spring integration - what is the best method in late 2010?

2010-09-15 Thread Jason Hatton

I would highly suggest going back to my recommendation, lalit's idea is good
but, my example is more complete, takes less effort to implement and is
easier to extend.   Especially with the use of gwt-dispatch and
implementation of a GWT architecture pattern implementation from the Google
I/O talk on GWT from the last session.

Then you probably should use something like ClickableTextCell, rather
than relying on selection.

How to handle celltable selection events?

2010-09-15 Thread chiappone

I am using M3 and want to be able to click on a row of my table and be
able to listen for that event.

I have the following which works fine:

private SingleSelectionModel setSelectionModel(
CellTable cellTable) {
final SingleSelectionModel selectionModel = new
SingleSelectionModel();

Handler selectionHandler = new SelectionChangeEvent.Handler() {

@Override
public void onSelectionChange(

com.google.gwt.view.client.SelectionChangeEvent event) {
// User user = 
selectionModel.getSelectedObject();
dispatcher.execute(

getRealtimeAction(DEVICE_CHANNEL, selectionModel

.getSelectedObject().getDeviceId()),
new 
ActionCallback() {

@Override
public void 
onFailure(Throwable caught) {
// do nothing
}

@Override
public void 
onSuccess(RealtimeResult result) {
// 
GWT.log("POSTED REALTIME");
}

});

DisplayMessageEvent.fireMessage(eventBus, 
"Loading...");

}

};


selectionModel.addSelectionChangeHandler(selectionHandler);
// cellTable.setSelectionEnabled(true);
cellTable.setSelectionModel(selectionModel);

return selectionModel;
}

The problem with this is that if the row is already selected you
cannot select it again.  I want to fire the event not only
onSelectionChange but just Selection.  Thanks.

Re: AJAX call doesn't ever seem to get made

2010-09-15 Thread Brett Thomas

Yeah that's what I meant - the server log on a deployed app. I can't
remember why I was looking at errors there rather than the development
server, probably was just using it wrong.

Post a followup if you figure it out.

Re: Development Mode performance with Chrome

2010-09-15 Thread e...@2010

I would like to echo the sentiment of this request and in a similar
vein (and maybe this deserves a separate post) there is also an issue
with the performance of Chrome in compiled mode in the following
scenario:

I am using WebGL and when creating very large Float32Arrays (of maybe
90,000 elements) it takes an exceptionally long time. I am creating
only a few of these large arrays and it is instantaneous in Firefox
(less than two seconds as I would expect) but takes 8 minutes(!) in
the latest version of Chrome (and all previous versions). One thing
that I observe during these 8 minutes is that the page fault rate
(Windows XP) is about 160,000 page faults per second (for the entire 8
minutes) for the Chrome process and the VMSize is going up and down
all the time (varying from say 40MB to 50MB) instead of growing
monotonically. It certainly seems to be some kind of O(n*n) problem
and maybe even the garbage collector could be running as each element
of the array is allocated? I don't know.

Any ideas?

Thanks, Ed

CssResources and inheritance

2010-09-15 Thread stuckagain

Hi,

I wanted to post this to GWT contribs, but lets try this newsgroup
first.

I have create my own button widget (based on a A href='#' tag) that
allows me to specify the styles through a CssResource called
ButtonCss.

I needed many different type of buttons in one application so I
thought, well simple I just define the button styles multiple times in
different .css files and such through different entries in the
ClientBundle.

For example I have the following:

interface ButtonCss {
 String button();
 String disabled();
}

Resources extends ClientBundle {

}

Re: GWT 2.x/Jboss/Seam gen

2010-09-15 Thread Karel Piwko

Hi Flavio,

if I got your question right, you can use following maven snippet to run
hosted mode with your configuration after deploying *exploded* WAR to
JBoss AS with ${context.path}:


  
 ...
 
package

   
  org.codehaus.mojo
  gwt-maven-plugin
  1.3-SNAPSHOT
  
 
run-devmode
package

   run


http://localhost:8080/${context.path}/devmode.html

true
0.0.0.0   

/jboss-as-home/server/default/${context.path}

 
  
   

 
  
 
If you're not using Maven, but Ant, which is probable if you used
Seam-gen ;), there will be similar arguments as in plugin configuration
you can pass.

Karel

GWT with Hibernate - Gilead vs. Beanlib

2010-09-15 Thread Flori

Hey all,

To use my hibernate entities with Beanlib i need two lines of codes:
HibernateBeanReplicator replicator = new
Hibernate3BeanReplicator(null, null, myVetoer);
MyHibernateServiceObject serviceObject =
replicator.copy(myHibernateServiceObject);

Why Gilead makes the whole so complex, why should I use Gilead instead
Beanlib?

Can someone explain that to me?

cheers!

Re: Custom map

2010-09-15 Thread Mikael Couzic

I heard some guys did pretty crazy stuff with OpenLayers, like Tetris-
style games. So I guess displaying an image in background and some
clickable geometries and/or icons on top should be pretty easy.
BTW, OpenLayers is a web mapping JS library. Check out its GWT wrapper
(GWT-OpenLayers) if you plan on using it in a GWT project.

Re: AJAX call doesn't ever seem to get made

2010-09-15 Thread Johannes Lehmann

Well, the method is called on the client side is called just fine (the
breakpoint where the method is called gets hit), but of course from
then on I can't trace calls any further since it's automatically
generated code (the service proxy). However I am certain that nothing
ever reaches the server for two reasons:
 -The breakpoint on the ServiceImpl method is never reched
 -The Firebug console, which shows all requests which are made,
indicated that no request is ever made. Since that should sit right
between the generated JavaScript and the server, it should definitely
show up if anything at all is sent to the server.

Incase I am wrong in my reasoning somewhere, where is the appengine
error log? I can't find it, embarrisingly... You don't mean the
messages that are normally logged in the Console / the web interface
to the actual appengine (rather than the development server), do you?

Thanks,

Johannes

Development Mode performance with Chrome

2010-09-15 Thread Brian

Can Chrome be made faster in development mode?

I use Chrome as my default browser as I really like the development
tools, but it's slow with gwt development mode.  On a table cell,
there's a click handler.  The click handler displays a popup built
with UIBinder.  In development mode with Chrome (v 7.0.517.5), it
takes approx 3 seconds from click to seeing the popup.  With Firefox
(3.5.11) it's 'almost' instant -- fast enough anyway that it's not a
performance issue.

In Web Mode with everything compiled, Chrome is super fast again, no
issues at all.  The perf loss is only in Dev mode.

Any ideas?  Should I switch over to the production branch of chrome
(and thus lose speed tracer)?

i have a great problem in my application. I have integrated a map with

Re: AJAX call doesn't ever seem to get made

2010-09-15 Thread Johannes Lehmann

OK, I fixed the problem now: One of the arguments of the service call
was a class called Item (which I defined). If I pass a Long instead
which happens to be possible but inconvenient, it works. This is still
incredibly puzzling since another service call returns a List
and that works fine, hence the problem can't be that GWT can't
serialize my Item class properly

Re: Rapid development of desktop-like web applications

2010-09-15 Thread csaffi

Thank you for your answer Kasper.

> What about Eclipse with GWT Designer, GWT and GAE ? That's what I use...
I'd like to try GWT Designer but now Instantiations was acquired by
Google and GWT Designer is not available on 
http://www.instantiations.com/gwtdesigner...

Perhaps it's now replaced by http://code.google.com/eclipse ?

Does GWT Designer let you visually design UI and bind data ?


Thank you very much for your help

Native Event either skips my code or doesn't call my event handler

2010-09-15 Thread Bernmeister

Using GWT 2.1.0 M3 with the following code snippet:

@UiField ListBox myListBox;

. . .

Window.alert( "here" );
ChangeEvent.fireNativeEvent( Document.get().createChangeEvent(),
myListBox );
Window.alert( "there" );

I get "here" but not "there".  Further, the event handler is also
subsequently called...

@UiHandler( "myListBox" )
void handleSelection( ChangeEvent changeEvent )
{
Window.alert( "everywhere" );
}

and I get "everywhere".  This is strange as it seems as if the event
is fired and calls other code, but does not return to continue
execution (as "there" is not pumped out).

If I alter the event call to be

ChangeEvent.fireNativeEvent( Document.get().createChangeEvent(),
this );

where 'this' is an object which extends Composite, I get "here" AND
"there" but not "everywhere".  That is the event handling code is not
triggered.

So what is the correct way to trigger an event such as a list box's
value being changed?


Thanks in advance,

Bernmeister.

Re: Re: function as parameter

2010-09-15 Thread Gal Dolber

Command is a simple java interface.
You can define your own.

public interface YourFunction {
void execute(String value);
}

public void processFunction(YourFunction f) {
f.execute("yeah");
}

To call:
processFunction(new YourFunction() {
public void execute(String value) {
 // Do something
}
});
