Unable to compile code

[Rick]

Hi all

I have just shifted my application to GWT 2.0  from GWT 1.7 as
discussed in http://code.google.com/webtoolkit/doc/latest/ReleaseNotes.html.
But In new development mode window there is no option for compile/
browse to check my code in compile mode. Also I have applied a
Window.alert in onModuleLoad to check whether it is reflecting or not.
By clicking on 'Launch Default Browser' my application get run in
Mozilla but Window.alert is not coming. It is showing previous
compiled version(The version I compilled with GWT 1.7 jars)

Thanks and regards

Rick

That makes sense for the plugin; could you not have the update site
list the current plugin and current-and-previous SDKs, allowing people
the option of installing GPE 1.2 with SDK 1.7.1 after a few checkbox
clicks?

Re: GWT 2.0 Using External Resources

[fmk11]

Thanks everybody, I got it.

If someone encounters the same issue, this is what I did:

1) I'm using @Source as Thomas suggested.

2) Your css file should be in the classpath (I was trying to reference
a css in my normal dir structure for that: /public/stylesheets, that
does not work).

Re: Installing GWT Eclipse plugin, version 1.1.0

[Javier]

Rajeev, thanks for your reply.

> You can use the Google Plugin for Eclipse 1.2 with GWT 1.7 - they are
> compatible.

If this is the case, I don't care at all about which GPE version is
exposed via the update site, so long as it works with GWT 1.7.1.  So
GPE 1.2 will work for me.

> So, you can install the latest plugin from the update side BUT
> exclude the installation of the SDK.

This is my problem.  I want to be able to install the GWT 1.7.1 SDK
via the update site on a brand new Eclipse installation, which doesn't
have any GWT SDKs.  Currently there is no mechanism for selecting the
GWT SDK to be installed: the update site currently forces you to pick
GWT 2.0.0.

Downloading the whole GWT distro just to tell Eclipse to use that
particular SDK sounds pretty silly, specially when I was able to do it
seamlessly via the update site two months ago.

If I understand correctly, there is no real reason for disabling the
GWT 1.7.x SDK in the update site (as it could be used with the latest
GPE, so this combination wouldn't produce an invalid environment).
Could please confirm if this is correct?

Thanks again.

Re: development mode isn't updating

[Bonor]

First I couldn't see the refresh and breakpoint changes either in the
browser. I also never got the Extension prompt either (like it says in
http://code.google.com/intl/nl/webtoolkit/usingeclipse.html).

Try recompiling the project with GWT recompile. Then refresh the
browser and the prompt for the extendion will show. From there on it's
happy hour!!!

Thank you google!

GWT 2.0 - com.google.gwt.user.client.rpc.IsSerializable is mandatory again?

[Dop Sun]

While I upgraded my project settings to 2.0 (via Google Eclipse
Plugin), and have a runtime error while running in development mode:

com.google.gwt.user.client.rpc.SerializationException: Type 'xxx' was
not assignable to 'com.google.gwt.user.client.rpc.IsSerializable' and
did not have a custom field serializer. For security purposes, this
type will not be deserialized.

I believe this is resolved while GWT since 1.5, but it comes back 2.0
again?

Re: development mode isn't updating

[Łukasz Bachman]

Check out a basic project created by webAppCreator, launch it and look
for parameter "gwt.codesvr" in the URL. If Your app doesn't provide
this URL (for instance - it was lost during redirect) the development
mode will not work properly.

Cheers.

Re: StackLayoutPanel stacks not opening on click

FYI. This was only a problem for me with RC2. The problem's gone away

Re: Download GWT Development Mode plugin for Firefox

I used firebug on firefox to find where it was trying to download

I using a browser that is not the one that you will be using the
plugin for, as it might automatically install it.

Yes, I am. OK, that clears up some of the confusion.

I'm not totally sure what you're asking. The URL that I'm given in
Eclipse's Development Mode pane looks like (http://localhost:/
MyApp.html?gwt.codesvr=10.0.1.8:9997); I've included at the end of
this email the console warnings (which include the names of the files
that the browser is requesting and being returned a 404 for).

> Do you know if your browser has the GWT Developer Plugin installed?

Yes, I installed that.

Your help is much appreciated.

Re: Inconsistency (or a bug?) in application creation for GWT 2.0

[Chris Ramsdale]

In regards to the different artifacts that are produced by the webAppCreator
utility and the Eclipse plugin; at its core the webAppCreator simply creates
a skeleton web app that is not tied to a particular IDE. We do offer build
targets that will allow you to more easily import your project into Eclipse
(ant eclipse.generate), but even then we generate the associated .project
file in such a way as to let the developer choose how he/she wants to launch
the app (Java launch config vs. Web App launch config).

On the flip side, when you create a project with the Eclipse plugin, we *are
* able to make a few assumptions as to which IDE and launch config you would
prefer based on the environment from which you created the project.

Re: GWT 2.0 - Eclipse - Need to Recompile after every change

[Chris Ramsdale]

We'll definitely update the sample project and doc, thanks for the good
find.

The workaround will in fact work, but I might add a check for the existence
of the gwt.codesvr query param and, if present, add it's value to the
redirect URL.

For example:

String gwtCodeSvrParam = Location.getParameter("gwt.codesvr");

if (!"".equals(gwtCodeSvrParam)) {
  signInLink.setHref(loginInfo.getLoginUrl() + "?gwt.codesvr=" +
gwtCdeSvrParam);
}

Where to put server-configuration property files?

[jbdhl]

I have a bunch of settings that are installation specific (e.g.
database connection properties) that I store in a property file. But
where should I put a file like this? I would like it to stay unchanged
between two deployments, so I guess the file should not be part of the
war-file (because it's installation specific and should somehow just
be considered as a static ). The war-file should, at most, contain
some kind of template for the property file. But if it's not part of
the war dir, how do I then refer to it? I need to know where to find
it.
So in general: Where do you put installation specific server-side
config files (property files)?

Re: Deprecation warning in all RPCs dealing with collections on GWT 2.0 RC2

In fact, there is a very easy way to reproduce it:
Just create a RPC method which returns List>. You'll see

Thanks. I guess the answers to c) and d) are

  c) by making the project use "Google Web Toolkit" as explained
above.

  d) I guess I don't: If I make one initial compile using ant, the
jar's will already be placed in WEB-INF/lib and a conventional GWT-
button-compile will (probably) suffice.

I still don't understand the inconsistency of the generated contents
by the two methods described in question a).

Re: Deprecation warning in all RPCs dealing with collections on GWT 2.0 RC2

[Luis Fernando Planella Gonzalez]

Just found the answer, and luckily in my case it was simple to
solve
I have a subtype of List called PageImpl, which had another
List containing the page items, plus the total count.
Then (and I think is a problem in GWT compiler), the compiler resolves
FocusListenerCollection, which extends ArrayList to be
a subclass of List.
As a result, ALL occurrences of Collection of anything in any RPC
method, by having PageImpl as a subclass of collection, had added
those ListenerCollections as possible result types, generated code to
handle them (50k in my case) and issued the warnings.
The solution (in better words: hack) was to change PageImpl to not
have a List of page items, but a LinkedList (it then converts the
receiving list into a LinkedList, which is even a penalty in my case).
As no ListenerCollection extends LinkedList, the problem is gone.

Ah, I also had an RPC which result type was List>. The
same problem. As it was just for testing, I changed it to List.

But I'd really want to hear from a GWT dev if this is not a bug in the
compiler...

Re: Installing GWT Eclipse plugin, version 1.1.0

[Rajeev Dayal]

We did not opt for this approach for simplicity's sake. Since we were
planning on maintaining backwards compatibility with previous SDK versions,
there was no good reason to provide older versions of the plugin for
installation.

If it is ever the case that we release a version of the plugin that breaks
compatibility with an existing SDK, we'll probably make both versions
available for download. Up till now, we have not made such a change.

Re: Installing GWT Eclipse plugin, version 1.1.0

[Rajeev Dayal]

You can use the Google Plugin for Eclipse 1.2 with GWT 1.7 - they are
compatible. So, you can install the latest plugin from the update side BUT
exclude the installation of the SDK. Even if you did install the SDK, it
does not automatically change your project over to use the new one, so you
would not be in a "forced upgrade" situation anyway.

As an FYI, whenever we release a new version of the plugin, we maintain
backwards compatibility with previous versions of the GWT and App Engine
SDKs. So, GPE 1.2 works with App Engine 1.2.0 - 1.2.8 and GWT 1.4 - 2.0. If
we ever decide to drop support for a particular SDK, we'll clearly call that
out in the release notes.

Re: GWT and .Net

[Adligo]

Hi,

   I used .net with C# successfully for zoomshare.com's domain
wizard.   C# has a nice Json api that saves some time, but then you
need to write your own Json readers for the GWT client.  I used the
regular GWT Java compiler for the client code, as I would expect
porting the GWT compiler would take MUCH MORE than a person year.

Cheers,
Scott

Re: GWT 2.0 Upgrade Problem

[Rajeev Dayal]

Are you using the Google Plugin for Eclipse? If you are, then it's not
necessary to make any changes to the main class - this is done for you
automatically by the plugin.

What is the URL that you're hitting your application with when you're trying
to debug it? It almost sounds like you're running in Web Mode instead of
Development Mode.

Do you know if your browser has the GWT Developer Plugin installed?

Another approach is annotations.  You can see an approach like this in
my little forms project, http://gxtforms.appspot.com/,
http://gxtforms.googlecode.com/.  Be sure to check out the source tabs
at the bottom.   I could see something like:

@Style(width=100, height ...)
class MyDialog() {
}

or

class MyPanel() {

  @Style(width=100, height ...)
  Dialog myDialog = new Dialog()

Just kind of thinking out loud here.

I know the Eclipse update system is capable of holding past versions
(and hiding them by default) although it doesn't seem like that's
what's being done in this case.  There may be good reasons for that
that i'm not aware of (e.g. the cross-compatibility of different
versions of the GWT SDK and the Google Plugin that could make the user
experience more painful if you chose to go that route), but ideally
I'd like to be able to get the plugin (new or old) with at least the
latest 1.X and 2.X SDKs for quite a while yet -- not everyone's going
to want to upgrade right away.

Is there something preventing this kind of approach?

Re: GWT 2.0 - Eclipse - Need to Recompile after every change

[ziggystardust]

Luis' suggestion offered a clue to what is going on here and I have
managed to figure out what the problem is. The StockWatcher
application is expanded in the example to include a Google Accounts
login (i.e. LoginService). What this does is that when the module is
loaded it checks to see if the users has already logged in. If not it
refers them to the Google Accounts login and in development mode this
is simulated. When you pass the page for the URL which the accounts
login page should return to and it doesn't include the gwt_codesvr=...
reference you loose the ability to debug the application and make
changes on the fly after login. This is why I would have to constantly
recompile the app. When it returned from the login page without the
gwt_codesvr reference it was picking up the app form the war directory
which would have been stale.

I suspect Google needs to update the documentation for the
StockWatcher example. What I had to do is append
"gwt.codesvr=localhost:9997" to the login and logout URLs. See below

private void loadLogin() {
// Assemble login panel.
signInLink.setHref(loginInfo.getLoginUrl() + 
"?gwt.codesvr=localhost:
9997");
loginPanel.add(loginLabel);
loginPanel.add(signInLink);
RootPanel.get().add(loginPanel);
}


and


signOutLink.setHref(loginInfo.getLogoutUrl()  + "?
gwt.codesvr=localhost:9997");

One needs to be careful hard coding these values though as they may
change if the browser is running on a machine tht is different than
where the development server is running or if using a different port
number.

Not sure if this is the best way to address this and if others have a
better suggestion I would appreciate it. I would consider this a
workaround at this point. Thanks Luis.

Installing GWT Eclipse plugin, version 1.1.0

[Javier]

Hello there:

our current project uses GWT 1.7.1 and, for a variety of reasons, we
don't want to upgrade to 2.0.0 yet.

I'd like to setup our current development environment on a new
machine; I'm at the point where I need to install the GWT eclipse
plugin, but when I go to the update site (http://dl.google.com/eclipse/
plugin/3.5) the GWT SDK has been magically upgraded from 1.7.1 to
2.0.0.

How can I install the previous GWT plugin for Eclipse (I believe
version 1.1.0) that uses the 1.7.1 GWT SDK?

Are previous versions of the GWT plugin being archived anywhere?

Ideally I don't want to have to download a separate GWT bundle
distribution on the side and then have to tweak Eclipse to point to it
(given that I was able to seamlessly install it in the past via the
site update).

If it's helpful in anyway, I'm using Galileo 3.5.1.

Thanks in advanced for any help.

If you change the domain you are making the HTTP request to, from localhost

Re: What is "main class"?

[Jaroslav Záruba]

I apologize if I confused you, I'm only reading through the GWT 2.0
stuff. I haven't faced this error myself as I'm yet to upgrade to 2.0.
(I have two days to a minor deadline, so I don't want to mess with my
dev.env.)
My understanding is that setting the main class is fundamental part of
the upgrade process, but I can't find it anywhere.
Or does it apply only when compiling without the Eclipse plug-in?

Re: UI Binder, really a good approach?

[Yozons Support on Gmail]

A GUI builder would be a huge advance over UiBinder alone, by my vote!  But
then again, a GUI builder would be best if there were a big widget library
so there would be more to use and layout.

SmartGWT has some nice widgets, but their GUI builder doesn't do GWT, just
JS.

GWT module 'XYZ' may need to be (re)compiled

[graffle...@gmail.com]

I have upgraded to GWT 2.0 - all works fine in DevMode

When I build a .war file and deploy it to my tomcat6 server, the
browser displays an alert "GWT module 'XYZ' may need to be (re)
compiled" when I bang the url.

Is it possible that one of my sub-modules needs to be recompiled under
V2.0?  I'm using GXT and Gilead (aka hibernate4gwt).

Many thanks on any input.

  - Bob

Re: UI Binder, really a good approach?

[Jonas Huckestein]

Its interesting that you mentioned how multiple "personalitites"
having to deal with css, html, java etc are harmful to the development
process. I think that while it does make sense to develop all program
logic in one language (particularly server and client code), neither
the GWT 1.7 style UI Java nor declarative java are really suited for
web development. In our team we have a designer who builds mockups in
Dreamweaver and to us it was a huge relief to finally be able to
simply copy and paste from his templates into our program. :D

And as has already been mentioned building an actual GUI editor on
UiBinder is not a huge problem (perhaps we can even integrate it in
Dreamweaver, dear Google?). It is much more dificult to do that on top
of declarative Java :)

Cheers, Jonas

GWT 2.0 Upgrade Problem

[Chris]

Hi

I've set up a brand new Mac with GWT 2.0 running under Eclipse
according to the instructions at (http://code.google.com/webtoolkit/
usingeclipse.html), and the template app runs fine. However, when I
checked my own GWT project that ran fine under GWT 1.7, and followed
the steps in (http://code.google.com/webtoolkit/doc/latest/
ReleaseNotes.html#Upgrading), the GWT portion of the app doesn't
display at all (the static HTML is displayed, just not the GWT part).
(Note: I have replaced the old style div-based method of including the
GWT app with the new script-based method; neither works, though.)

I'm noticing a couple of 404 warnings on the console (indicating that
"/myprojname/CA786633770B20A7881AAE6CBEB6.cache.html", for
example, can't be found—and indeed it doesn't exist). I guess this
might have something to do with the problem, but I'm not sure what to
do about it.

(One part of the upgrade instructions (link above) that I didn't
understand was about changing from com.google.gwt.dev.HostedMode to
com.google.gwt.dev.DevMode. It's not clear where this should be done
and I'm not seeing the warning about the former being deprecated,
anyway.)

Lastly, I'm using GWTCanvas (I'm using the 1.7 jar), if this makes any
difference, although no part of my app gets displayed (except for the
static HTML surrounding the app).

I'd be really grateful if someone could suggest a way forward.

Thanks in advance

—Chris

As pointed out by Jonas, there is a way to restart the server from the
Development Mode View. When you mention that you prefer the tabbing, do you
mean the organization of the tabs? Or do you just prefer the navigation
style of using tabs as opposed to the breadcrumb layout? Keep in mind that
you can switch the layout of the Development Mode View by clicking on the
arrow in the upper-right hand corner of the view.

That is the case in the Development Mode View as well - the Server messages
are logged to stdout. However, we only log HTTP requests that result in an
error. If you want to see the HTTP log messages in the Development Mode
View, turn the log level up to TRACE in your launch configuration.

Re: Eclipse Plugin for GWT 2.0 release

[Rajeev Dayal]

Actually, there is no way to go back to the GWT 1.7-style Hosted Browser.
The workaround I gave disables the use of the Development View in Eclipse,
but it will still bring up GWT's own Development Mode UI, which requires the
GWT Developer Plugin to be installed in your browser.

For the ssue that you're experiencing, it might be best to start a new
thread about it.

Re: GWT 2/Eclipse Project References

[Rajeev Dayal]

This is a general problem with having your GWT or App Engine project depend
on another project that ultimately contributes artifacts to the
war/WEB-INF/lib folder. We're going to address this in a future version of
the plugin.

Even though this appears to work in GWT, you'll still have to revert to the
clunky technique (exporting the files from the parent project and copying
them into the war/WEB-INF/lib folder of the child project) when you perform
a deployment; the Google Plugin for Eclipse will not automatically do this
for you.

Reading the *.rpc.log and understanding why classes are included in the serialization policy file.

[Alex]

I'm looking at the *.rpc.log for one of my RPC calls and don't
understand why some classes are included in the policy file. As an
example consider the PopupListenerCollection. The line below appears
in the x.gwt.rpc file.

com.google.gwt.user.client.ui.PopupListenerCollection, true, true,
false, false, com.google.gwt.user.client.ui.PopupListenerCollection/
3060919138, 3060919138

In the *.rpc.log I see this

com.google.gwt.user.client.ui.PopupListenerCollection
   Serialization status
  Instantiable
   Path
  'com.google.gwt.user.client.ui.PopupListenerCollection' is
reachable as a subtype of type 'interface java.util.List'
  'java.util.List' is reachable from field 'values' of type
'com.lombardi.online.model.client.ClientPropertyValueList'
 
'com.lombardi.online.model.client.ClientPropertyValueList'
is reachable as a supertype of type 'class
com.lombardi.online.model.client.ClientLiteralValueList'
  'com.lombardi.online.model.client.ClientLiteralValueList' is
reachable as a supertype of type 'class
com.lombardi.online.model.client.ClientConcatenatedLiteralValueList'
  ...

The piece I don't understand is

'java.util.List' is reachable from field 'values' of type
'com.lombardi.online.model.client.ClientPropertyValueList'

The definition of ClientPropertyValueList starts with

public abstract class ClientPropertyValueList
implements IsSerializable, Serializable, PropertyValueList {
/**
 * The list of property values in this list.
 */
private List values = new ArrayList();

So the type of P must be a subclass of PropertyValue and I don't
understand why the serialization code thinks a PopupListenerCollection
could be assigned to values.

Someone please tell me what I'm doing wrong here.

Re: how to resize a DockLayoutPanel pane using gwt 2.0 and uibinder

[morte...@gmail.com]

I just tried this (in 2.0GA), and I get errors in the generated code:

ui.xml looks something like this:





...

it complains about a type mismatch, when looking at the generated code
it is obvious why but not how to fix it:

 public Widget createAndBindUi(final Trinity owner) {

bam.trinity.client.Trinity_BinderImpl_GenBundle
clientBundleFieldNameUnlikelyToCollideWithUserSpecifiedFieldOkay =
(bam.trinity.client.Trinity_BinderImpl_GenBundle) GWT.create
(bam.trinity.client.Trinity_BinderImpl_GenBundle.class);
bam.trinity.client.Trinity_BinderImpl_GenCss_style style =
clientBundleFieldNameUnlikelyToCollideWithUserSpecifiedFieldOkay.style
();
bam.trinity.client.ui.ContentPanel bottomPanel =
(bam.trinity.client.ui.ContentPanel) GWT.create
(bam.trinity.client.ui.ContentPanel.class);
com.google.gwt.user.client.ui.HTML left =
(com.google.gwt.user.client.ui.HTML) GWT.create
(com.google.gwt.user.client.ui.HTML.class);
com.google.gwt.user.client.ui.HTML right =
(com.google.gwt.user.client.ui.HTML) GWT.create
(com.google.gwt.user.client.ui.HTML.class);
com.google.gwt.dom.client.SpanElement headerspan = null;
java.lang.String domId0 = com.google.gwt.dom.client.Document.get

bam.trinity.client.ui.ResizableDockLayoutPanel rootPanel = new
com.google.gwt.user.client.ui.DockLayoutPanel
(com.google.gwt.dom.client.Style.Unit.PX);


On the last line here, the ResizableDockLayoutPanel is for some reason
set to "new DockLayoutPanel" and not ResizableDockLayoutPanel..

Maybe I did something dumb, but I can't really find it :)

Re: UI Binder, really a good approach?

[Sekhar]

UiBinder is actually quite similar to the approach Flex takes
(splitting into MXML and ActionScript). It seems like overkill
initially, but really pays off for larger projects (separating the
design/logic and adding flexibility).

Re: Development Mode Firefox 64bit Linux Issue

Hi all,

I found that if (using Firefox) I went directly to the link rather
than clicking the 'Install' options on the page the 'Add on' installed

Specifically I right clicked the link and checked what href it

I'm sorry I didn't make note of the link.

Chrome loading indicator

[Andrey]

Hello!

I am using comet (server push) in my application. When user logs in a
secondary connection being created. It is an ordinary GWT RPC call
with 50 sec timeout and retry.

Everything is OK except that Chrome and the Chrome only shows loading
indicator as if the page is loading.
How can I get rid of it?

Thanks in advance!

Re: Download GWT Development Mode plugin for Firefox

[Rajeev Dayal]

I'd recommend that you initially have your system connected to the Internet,
and when you first access your GWT Application in development mode via the
browser, you'll be prompted to install the GWT Development Mode plugin.
After that point, you can debug your GWT Apps without having to be connected
to the Internet (for that browser).

Running in "no server" mode has nothing to do with being connected to the
Internet - you only need to use that option if you don't want to make use of
GWT's embedded web server (i.e. you have a back-end with a specific
configuration set up already that you'd like to use).

If the browser is not triggering the download, you may be getting bit by the
issue of having a stale hosted.html file after switching SDK versions. This
is a bug that we definitely need to fix.

Delete the generated directory in your war folder, and then try hitting your
GWT App again. If the download is not triggered, hold down the SHIFT key and
hit Reload in your browser. That should force your browser to request the
new version of hosted.html, ignoring any files in its cache.

If you have any other questions about GWT 2.0's integration with Eclipse,
please do ask. We definitely do not want people to be confused about it :).

[Jason Parekh]

Hey,

Thanks for reporting this, definitely seems like a bug in the plugin.

First, could you try forcing a clean build of your project?  (Project
> Clean)  This will force a re-indexing of the UiBinder indices.

Also, could you check your Eclipse log for any errors?  The log file
lives at your workspace/.metadata/.log .

A few more questions:
- Which package does your Pjat class live in?
- What version of Eclipse are you using?
- What operating system are you running?

Thanks!

Re: UI Binder, really a good approach?

[Nicanor Cristian]

UI Binder is the step before that. On top of UI Binder it's easier to
write a WYSIWYG GUI editor, than on top of plain java. Also it's very
easy to mantain the MVC structure.

Re: GWT and .Net

[Olivier Gérardin]

Do you still have a reference to the posts that linked .Net with GWT?
I have serious doubts that this was ever considered.
Besides, if all you want to do is be able to code in C#, I think Java
is close enough that it won't be a huge gap... In addition to porting
the GWT compiler, fully supporting C# would mean porting some
core .Net libraries so that they can translate to JavaScript (just
like GWT's JRE emulation lib), rewriting widget libraries and all
translatable GWT code, and also porting the development mode shell.
Not likely.

You can of course run GWT with a .Net backend, but you'll have to take
care of serialization/deserialization, because only the native RPC
mechanism does so transparently. You may use JSON or XML or any other
format, but you'll have to do the parsing yourself (there might be
tools around to make that easier ..)

Re: UI Binder, really a good approach?

[Arthur Kalmenson]

I think you just have to try it and see. We're doing that here to
determine if UiBinder is a better way of building user interfaces, or
if we prefer building UI in a Swing like fashion. There are arguments
both ways, but it comes down to taste and preference. UiBinder allows
for web designers to be more involved in the creation of GWT
applications and in many organizations that's a huge benefit. Another
benefit of UiBinder, is that you can use standard HTML elements inside
an HTMLPanel to get higher performance as per Kelly Norton's Google
I/O talk. Now you can do it in a syntax highlighted, code completion
way instead of a Java strings.

Re: Window on top

[Jesper]

The "newWindow" parameter is that browser window identifier as seen
from JavaScript.

To get more browser windows, you have to change that token each time
you call Window.open()

Re: Deprecation warning in all RPCs dealing with collections on GWT 2.0 RC2

[Ashar Lohmar]

Hi I'm having the same kind of problem.
in my app i use some libraries/object written in Java 1.4 style
the objects implement Serializable but contain Lists or Maps which are
declare without parameters
 i mean List instead of List, as the Java 1.4 requires
and some RPC classes return this kind of objects but on Gwt-compiling
I endup with a lot of code referencing all kinds of Listeners and
stuffs that are unrelated to the RPC service.

Basically the messages appear because the Listeners are deprecated,but
what are they doing there in the first place ?

hope someone will clear this up

Re: Development Mode Firefox 64bit Linux Issue

What is "main class"?

[Jaroslav Záruba]

http://code.google.com/webtoolkit/doc/latest/ReleaseNotes.html#Upgrading
--
After upgrading to the GWT 2.0 jars, you will see the following
message when running development mode using HostedMode:

[WARN] The class com.google.gwt.dev.HostedMode is deprecated and
will be removed --
use com.google.gwt.dev.DevMode instead.

In order to eliminate this warning, change your main class from
com.google.gwt.dev.HostedMode to com.google.gwt.dev.DevMode.
--

This is the first time I hear/read about that class. (I can't find
anything like "main class" anywhere in the Eclipse or project
settings.)
Is it something that is available for change only after upgrading to
GWT 2.0?

No, but the GEP will make things *VERY* *easy* and *fast*. So everyone will

I guess you ask that because you do not want to use eclipse?, but believe me
it is worthed.

Window on top

[Mike]

Hi all,

My application frequently needs to open a new browser window to
display some information to the user that cannot be displayed within
the main application window.

The first time I open that window (using Window.open(newWindowURL,
"newWindow", ""); ) the new window is raised to top. However, on
subsequent openings, the contents of the new window is just replaced
(which is exactly what I want) without the new window being raised to
top. How can I get the window raised in such cases?

Thanks, Mike

External Javascript method call

[JavaDoc]

Hello,

Ive associated a certain FooBar.js to my module.
The javascript has a method Foo(), which I need to invoke.

I am trying to do this through JSNI, however, its failing. Heres my
code:


public native void doSomething() /*-{
var bar = new Foo();
//some other stuff
}-*/;

This method is being called through an onClick event of a GWT button.

I am however, getting this exception in my console:


[ERROR] Uncaught exception escaped
com.google.gwt.core.client.JavaScriptException: (TypeError): 'Foo' is
undefined
 number: -2146823279

Please help me out :(

API Translate

[Dominik Franek - CZE]

Hello,
I have a little problem, I wanted to create a GWT application using
Translating API: http://code.google.com/p/google-api-translate-java/
and when I click Run as Web Application (Eclipse with GWT) I get these
error:
[TRACE] Loading inherited module 'com.google'
[ERROR] Unable to find 'com/google/api/translate/Language.gwt.xml' on
your classpath; could be a typo, or maybe you forgot to include a
classpath entry for source?
[ERROR] Line 15: Unexpected exception while processing element
'inherits'
[ERROR] Failure while parsing XML

I added to APTranslator.gwt.xml this line:

it looks like this:

http://google-web-toolkit.googlecode.com/svn/tags/1.7.1/distro-
source/core/src/gwt-module.dtd">

  
  

  
  
  
  
  
  

  
  
  
  


I clicked right-mouse on Project, selected Properties - Java Build
Path - Libraries
and there I added JAR: google-api-translate-java-0.91.jar which is in
lib/ folder in project folder.

Do you have any idea, where can be a problem? I tried to add the JAR
many times in different ways, but nothing helped me :)

Thanks

Unicode

I want to implement a module able to open an Unicode Arabic file and

I think this is very easy for expert GWT designers.

I'm running gwt-2.0.0 on ubuntu with ff 3.5.5. I've reinstalled the ff
plugin several times (I had been using an older trunk one) but now I
have 1.0.7263 installed.

I really have no idea how to proceed here.

I set a debug point for HostedModeException--in SchedulerImpl:163, for
t.isRepeating() (in the 2nd stack trace), t was actually showing up as
null in the debugger. Which I'm guessing is just an artifact of it
being a js object because it wasn't NPEing but instead doing this
invokeNativeBoolean call.

Does this look like a ff plugin problem? A gwt problem? Any hints of
what I should look at/try next?

Thanks,
Stephen

GWT 2 DevMode not working against an external server

[Robert Schultz]

I'm having trouble getting DevMode working in GWT 2.0 with an external
server

I've upgraded from GWT 1.7 to GWT 2.0

It compiles my GWT module correctly when I run
com.google.gwt.dev.Compiler with arguments:
-war /path/to/web/gwt com.my.path.mymodule.mymodule

I have my own tomcat server and web.xml configuration.

I serve up HTML code myself in which I include in the :


I can then visit my server http://localhost:7100/myapp/MyPage
This loads up the web based GWT code and everything works great.


DevMode however is not working.


I am launching com.google.gwt.dev.DevMode as a Debug Configuration
with arguments:
-noserver -startupUrl http://localhost:7100/myapp/MyPage
com.my.path.mymodule.mymodule

I also have on the 'Classpath' my /src directories for my projects
that contain GWT code.

It correctly opens the "GWT Development Mode" window.

I hit 'Launch Default Browser' button and it opens in Firefox:
http://localhost:7100/myapp/MyPage?gwt.codesvr=127.0.0.1:9997

I correctly see under netstat that it's listening on 9997.

I never hit any of my GWT breakpoints.
The page still works, clearly still using the web compiled JavaScript
instead of establishing a dev connection.


As a test I used the Google Eclipse plugin to create a test GWT
project.
I was able to launch a debug configuration for the test 'Web
Application' and hit breakpoints, step through code, etc.
So all my jars and browser plugins appear to be installed correctly.

Any ideas as to where I went wrong?

Add GWT to server side generated pages

[Borje Johnsson]

Hello all,

I have used GWT to build a couple of small apps from scratch and it
works great. But now I am trying to use GWT in some part of a bigger
application with mostly generated pages. Just a small part of the
application (outer head and body tags) uses a static html file.
Is there a way to add GWT support to part of the application (some
buttons will call on GWT functions and others will user ordinary form
submit)?

unable to specify war directory when running web app

[haole]

i'm using google plugin for eclipse 3.5 (galileo) with GWT 2.0.0 (and
app engine 1.2.8).

when i compile my GWT modules, i set the additional compiler arguments
to "-war war/foo." the behavior is as expected: the compiler creates
directories for each module under "war/foo." i get the following
directories when i compile only:

war/foo/mymodule1
war/foo/mymodule2
and so on...

when i run a web application, the compiler goes back to using the
default directory ("war") to create directories for each module. under
Run Configurations, there is no option to add additional compiler
arguments under the GWT tab. i get the following directories when i
run:

/war/mymodule1
/war/mymodule2
and so on...

clicking the refresh button in the hosted browser window seems to have
the same effect as running the web app: it uses directories in the
default location. even though the actual web page points to to the
"war/foo" location, the app reflects the new changes immediately. the
web page includes the following script:



i checked the actual output files to see which ones were modified and,
sure enough, war/foo/mymodule1/mymodule1.nocache.js was NOT touched.
war/mymodule1/mymodule1.nocache.js was modified. again: the web app
seems to reflect the changes, even though the script src points to the
non-default directory. i'm assuming that the client-side code is just
running in the same VM as the server in hosted browser mode.

i'm hoping that the option to specify additional GWT compiler
arguments can be added to the GWT tab under Run Configurations, just
as it is available under the GWT compile dialog.

Whenever I try to explore to possibilities with the new UiBinder,
Eclipse tells me that e.g.:
"Field button has no corresponding field in template file
Mail.ui.xml".

Even when I use the Eclipse Wizard "New UiBinder" the web app wont
build or run in dev-mode.

I have tried to import the Mail sample into Eclipse - no problem. But
when I try to add a new UiField, I get the error again.

It's probably a very fundamental error - and I apologize for any
inconvenience this post may cause - but I give it a try anyway.

Here's the wizard generated file Pjat

public class Pjat extends Composite {
private static PjatUiBinder uiBinder = GWT.create
(PjatUiBinder.class);
interface PjatUiBinder extends UiBinder {}
@UiField Button button;   // <-- This line gets a red underline
public Pjat(String firstName) {
initWidget(uiBinder.createAndBindUi(this));
button.setText(firstName);
}
@UiHandler("button") // <-- This line gets a red underline
void onClick(ClickEvent e) {
Window.alert("Hello!");
}
}
