Re: How does UIBinder attributes map to methods / properties of the Java object ?

[Chris Conroy]

Hi John,

The mapping is from the property name to a corresponding setPropertyName
method. See UiBinderWriter.genPropertySet. In the case of say , that translates to a call to label.setText("oh hai")

In the case of a grid, since there aren't such setProperty calls. You could
extend Grid and create your own relevant setProperty calls or you could mark
it as @UiField(provided=true) and simply initialize it yourself.

Hi,

Its not all files in the build output directory - our HTML files and
any static resources that are kept in 'src/main/webapp' and copied to
'target/' are left alone when starting dev mode.  Our
particular problem is that we had a separate maven resources project
that was being deployed to 'target/' during mvn:package, and
those exploded resources were being deleted when dev mode is starting
up.

I'm working in Windows XP.  The gwt-*.jar dependencies were
automatically added after - to answer your last question - I
configured the 2.1.0 SDK in project properties after upgrading the SDK/
plugin.  I'm fairly certain gwt-dev.jar shouldn't be a compile-time
dependency, right?  In any event, building/GWT-compiling work just
fine, the only problem is starting up dev mode.

I think I can reconfigure maven to explode the resources zip file to
src/main/webapp instead of target/ before compilation so
this likely won't be a long-term problem, but its still a change from
the behavior using the 1.3.3 plugin.

Many thanks,

This is happening to me, too, since I upgraded to GWT 2.1.0 and GPE
1.4.0 - I posted yesterday about the problem:
http://groups.google.com/group/google-web-toolkit/browse_thread/thread/d13a6ed3673baf3f#

As soon as you start dev mode, any resource files in the build output
directory (target/) that are not also present in src/main/
webapp are deleted.

Re: GWT client-side thread or asynchronous call ?

[Chris Conroy]

If you can target just HTML5, then you could use WebWorkers:
http://www.whatwg.org/specs/web-workers/current-work/

At the moment, you'll have to hand roll the JSNI to access them, but GWT
proper will be supporting HTML5 soon-ish.

Because we have 5 GWT apps using the same web resources and the point
was to avoid duplicating them 5 times in source control.

This isn't a GWT compiler issue.  Nothing in this folder is generated
by the compiler - all that goes to a subdirectory of target/.  Plus, this didn't happen with previous versions of GPE.  It
started after upgrading to 1.4.0.

> As a last resort, you can still use -noserver...

As a last resort I can simply copy the resources back into the folder
after GPE deletes them and before I load the app in my browser.  It
just seems broken that GPE is deleting whatever it wants from the
build output directory when starting Jetty.

Starting GWT dev mode within Eclipse causes Maven-managed resources to disappear

[Chris]

Hi,

I'm working on upgrading our development environment from GWT 2.0.4 to
2.1 - this involved upgrading GPE to 1.4 as well as the gwt-maven-
plugin to 2.1.  So far things have gone pretty smoothly except for one
nagging problem.

We have in our code tree a POM module that holds just shared resources
- images & CSS - that we make available to all GWT modules in our
codebase.  This is managed by maven-assembly-plugin that unpacks a zip
file from the repo into our target/ directory.

'mvn package' builds the directory structure correctly, and the
resultant war file can be deployed to an external Tomcat server with
no problem.  But when I try to run the app in developer mode it seems
that GPE is deleting the maven-assemly-plugin managed resources prior
to startup.

I've tried just about everything I can think of, but can't for the
life of me figure out why this resources directory is being removed.
Has anyone ever had a problem like this?

Thanks in advance for any help.

getting size of center in a docklayoutpanel

[Chris]

I have an application running in a DockLayoutPanel. I'm trying to
display an image in the center component (the center contains a
FlowPanel which contains the image) and have that image fill as much
of the center as possible. I'm doing this by setting the image width
to 100%. The problem is that if the browser is very wide the image
will overflow and get cut off at the bottom. In this case I'd like to
set it to 100% height so that this doesn't happen. I can't figure out
how to get the visible height of the center component to make this
change when the browser is resized.
Is there something obvious that I'm missing?

Thanks,
-Chris

Re: GWT debugging under Linux is much slower than under Windows - what's wrong with my configuration?

[Chris Conroy]

Your slowness is not a Linux vs. Windows issue: it is a Chrome plugin
vs. Firefox plugin issue.

The Chrome NPAPI based plugin is known to be a lot slower than the
Firefox XPCOM plugin. This is partly due to the out of process nature
of plugins in chrome: each JS<->Java boundary crossing incurs extra
IPC latency. Also, there are some object identity issues in the Chrome
plugin model that require us to do some performance harming
workarounds for the sake of correctness. We hope the object identity
issues will be worked out, and we should get a speedup from that.
There isn't a lot to be done for the out of process problem, and
Firefox will probably head in that direction in future versions (just
a guess).

The Firefox plugin should install just fine on 64 bit ubuntu--I use it
myself all the time. Some other distros have some shared library
conflicts. FWIW, there are some troubleshooting tips in this thread:

Re: GWT Server Side Javascript Interpreter?

[Chris Conroy]

Sean,

There is no javascript interpreter on the server side. Everything on the
server runs in the java VM. On the client side, everything is javascript
when running a compiled app.

In development mode, things get a little confusing. Where possible, your
client side code runs in the Java VM, and any javascript (JSNI, JSO, DOM
access, etc...) gets run in the browser. The bridge that makes this possible
is the devmode plugin.

Re: How do I check out the Samples into Eclipse

[Chris Conroy]

Import the existing projects from the samples directory. I don't understand
your complaint about having separate projects: the samples are distinct and
isolated from each other.

XML from external page

[Chris]

Hi all,

I've a question that is discussed a lot of times, but I couldn't find
a working solution.
Hope you can help me.

I have a gwt project that is currently working with servlets.
But for a new widget I need to request data from a site called
clinicalTrials.gov.
Unfortunately the only way they response data is in xml format.
See  http://clinicaltrials.gov/show/NCT1372?displayxml=true

I wrote a lot of things about cross site scripting but I guess there
isn't a way to get it working.

Then I had the idea to use a php file to get the data. That is working
really good but now I have the problem that it's not working in hosted
mode because of the running tomcat, but it's running on my apache live
server. But on the apache the java servlets aren't running.

Does anyone has an idea how to get this working? Doesn't matter if
it's cross side scripting or maybe a tomcat - apache bridge...

Thanks very much.
Chris

Re: Performance issues with large number of divs

[Chris]

Thanks Jeff. I had thought of that idea, but then I'd somehow need to
tie in to the GWT event model so that I could capture when people
click on this text, firing through all my presenters and event bus. (I
just realised that I missed that bit off the first message).

Perhaps though that is fairly trivial?

Re: Performance issues with large number of divs

[Chris]

Performance is more acceptable when not in Dev mode, but for small
texts, we're looking at the browser hanging for 2-3 seconds while it
renders. Would be keen too, to understand why dev mode is so much
slower!

Performance issues with large number of divs

[Chris]

Hi All

I have this application where I need to display lines of related text
one under the other. For e.g., the English text would be on top, and
then the Greek would be below. The text is split into phrases, so for
example, the Greek is not necessarily in the right word order. All
that matters is that the meaning of the greek word matches the meaning
of the english word.

How would you go about displaying this. I decided to go for a div
containing child divs for each word. Each parent div then floats to
the left, so that the wrapping of the text at the end of the page is
maintained.

The problem I have is 2 fold. For even small texts (~600 words), it
takes a while to generate the correct DOM (600 parent divs at the
minimum + for 2 lines 1200 child divs!). Are there ways of speeding
this up? At the moment, I take each word-set as it comes in and render
the div into the DOM tree. Would it be faster to do everything off the
DOM and then attach the whole lot at the end? I believe I tried that
months ago and it didn't seem to help much.

Secondly, I get the impression it takes a while to deserialise the
response from the server. For e.g. I have a response that is roughly
41Kb from the server, and it seems to take approximately 20 seconds to
deserialise.

All this is in DEV mode. In normal mode things are faster, but still
not fast enough...
Any ideas? I have a few thoughts, but I think that fundamentally this
might just not have a nice solution.

Re: CellList row data - possible bug?

[Chris Conroy]

setRowData deals with the visible display of data. What you really want to
do in this case is use a ListDataProvider. You can call setList on your
ListDataProvider and it will handle the updating for you. Somewhat
counter-intuitively, you add the display to the list provider--not the other
way around.

So...

ListDataProvder provider = new ListDataProvider();
provider.addDataDisplay(myCellList);
provider.setList(list_with_5_elements);

provider.setList(list_with_2_elements);

Re: Setting specific slice color in PieChart

[Chris Conroy]

It should work out of the box. One gotcha is that if you have a value that
is 0, the it won't take up a color slice.

See the SpeedTracer LatencyDashboard as an example:

Re: Collection.sort in Linux Chrome 7, negative zero bug

This is a known bug in V8. It was fixed here:
http://code.google.com/p/v8/source/detail?r=5631. Which made its way into V8
trunk in version 2.5.1. Chrome DevChannel is still affected AFAIK, though I
would expect an update to 2.5.1 in the next week or two.

Re: Change default browser in dev mode

[Chris Conroy]

I'm not sure what GWT DevMode gizmo you are referring to. Perhaps this is a
netbeans issue? GWT itself doesn't launch the browser except from GPE
(eclipse) or GWTShell, and GWTShell will only launch it if you hit the
'Launch Browser' button.

Could you post a screenshot of what you're talking about?

Even the old school GWTShell Swing GUI has a "Copy URL" button. So I really

Re: Strange compilation errors on linux platform

[Chris Conroy]

It looks like something about your images/system is causing ImageIO.write to
fail. My best guess is that it's returning that there are no available
ImageWriters, but the compiler incorrectly does not read the return value.

Any time the compiler dies with an NPE, we consider that a compiler bug. I
should have a patch later today to fail on this condition a bit more
gracefully. That said, the root cause will still mean your build won't
complete.

Re: 2.1 Documentation

GWT 1.6.4 question

[Chris]

I am working on an app that uses GWT 1.6.4 - I need to override the
RemoteServiceProxy stub that gets dynamically created when I call
GWT.create(Service) to set a custom header before it fires off the
request to the server.

I have found a way to do this using BindUI, however, upgrading GWT to
2.0 is not an option in this case.

Can anyone think of a *clean* way to do this across a large number of
services, without manually making changes to each service or how the
services are called?

Just to clarify, I donated my time to submit a few chapters and to
review some of the other content that is going into the book. And yes,
you read that right...I donated my time. We don't accept royalties at
Google. I can't comment on the amount of 2.1 content in the book, but
I can say definitively that the GWT team is in the process of wrapping
up documentation on:

- Cell-based widgets
- RequestFactory
- Activities and Places

Nested Layout Issues

[Chris Boldon]

I'm creating an application with a view based upon the
DockLayoutPanel.

I initialize a DockLayoutPanel and add SimplePanels to the north,
south, west, and center docks so I can pass them to the Presenters.

The presenter then adds a custom widget to the to the SimplePanel. The
custom widget contains a StackLayoutPanel (think left stackpanel
navigation like gmail). The issue is the stack isn't displaying
correctly, I'm only seeing the first stack in the panel.

If I add the custom widget directly to the DockLayoutPanel without
first adding a SimplePanel, it works fine. But this would mess up my
MVP coupling.

Any help is appreciated.

Re: Cannot create new web applications.

[Chris Conroy]

Justin, we'd all love to not have to deal with the hassle of moderation, but
sadly there are a lot of spammers out there. Only new members are
automatically moderated, and once a member makes some legitimate posts, we
flip the bit that allows them to post without being stuck in the moderation
queue.

Aptana doesn't support GWT directly AFAIK.

The Eclipse UI for the new project dialog is a bit confusing. You'll
probably need to select File->New Project->Google->Web Application Project.
The plugin should also add a few buttons to your toolbar including one for
just this action.

Re: GWT Complier OutOfMemory issue

[Chris Conroy]

This doesn't address code-splitting per-se, but r8921 and r8850 reduce both
DevMode and compiler memory footprint.

Re: Monitor GWT 2.x application traffic using packet analyzer

[Chris Conroy]

you can pass -bindAddress to bind to a different interface (0.0.0.0 to bind
to *). Also, Wireshark is perfectly capable of capturing traffic on on
127.0.0.1. You just need to set the interface to lo (loopback) rather than
your actual NIC.

Re: Uibinder, @sprite and ui:with ClientBundle ImageResource, HOW?

[Chris Conroy]

Andrew,

Sorry for my originally hasty reply. Turns out that the docs aren't clear
about this at all, but this is a current limitation of 

You will have to use something like this, at least for now:


  @sprite .x {
gwt-image: 'someImage';
  }


We'll be updating the docs on this and looking to enable this use case at
some point in the future.

Re: Development Mode not connecting

[Chris Conroy]

Sounds like perhaps you have an existing DevMode session active, and perhaps
you launched it with "Run as..." rather than "Debug as...". It's easy to
accidentally keep an old DevMode session around in Eclipse because the UI
for it is a bit non-obvious. Though, if you are using the same run
configuration then it should complain in the console about not being able to
bind to the code server port since another session is active.

Re: Singleton Class in Development Mode

[Chris Conroy]

Assuming this is on the client side, each refresh gets its own ClassLoader.
So, you won't be able to persist state on the client across a refresh this
way. The VM is not spun up again, but the effect is similar for this use
case.

Re: GWT Complier OutOfMemory issue

[Chris Conroy]

That should be more than enough memory to run your compile. Do you have a
stack trace for the OOME?

FWIW, I have a pending change that should decrease the amount of memory
needed to run a compile or DevMode.

Re: GWT Hosted Mode Slow

[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.

Re: display slanting X-axis in gwt visualization column chart using gwt-visualization-1.1.0.zip

You should direct questions about the Google API Libraries for GWT to the
forum dedicated to that purpose:
http://groups.google.com/group/GWT-Google-Apis

I'll take a stab at your
question: you don't list calling the draw method. Make sure you call
.draw(yourData, yourOptions) on the visualization for the options to take.

P.S. that flag needs to get passed in the JVM arguments. Also note you'll

Re: Any news on when super dev mode will be released?

[Chris Conroy]

Paul,

We're actively working on it. Note that 'super dev mode' isn't quite in
existence yet, it's more of a goal than a concrete thing at the moment.
Though there was a short lived branch with that name--most of those
particular changes have already gone in.

If you like, you can profile DevMode by running GWT from trunk and passing
-Dgwt.speedtracerlog="/path/to/myproject-st.html" which will cause DevMode
to output a SpeedTracer log to that file. You can then use the Chrome
Extension SpeedTracer to inspect the generated log to see where DevMode is
spending time for your app. If you'd like to share, you can feel free to
post screenshots of the SpeedTracer detail view for your Module Init.

Re: Memory Leak IE7 & GWT 2.0.4

[Chris Conroy]

Okay, well if it's *in* hosted mode (read: the JVM), then it's a known issue
that I'm working on at the moment.

You need to set the "GWT Nature" on the project. Right Click -> Google ->
Web Toolkit settings -> Use Google Web Toolkit (and select the SDK you want

server side code not rebuilding

[Chris Broglie]

I'm developing using the eclipse plugin, and a lot of the time when I
make changes local to the server code, the changes aren't visible when
I reload the page. Client side changes are always reflected (as
expected). Is there something I need to do to force the server code to
be rebuilt by eclipse?

Re: How to run my DETAILED/PRETTY compiled GWT application locally / on app engine?

[Chris Conroy]

When you run from eclipse, you are running in DevMode which does not cause a
recompile.

If you compile your app as you like (with DETAILED or PRETTY), run from
Eclipse, and then strip the ?gwt.codesvr fragment from your URL, you'll be
served up the DETAILED or PRETTY compiled version that you just created. For
the vast majority of your issues though, debugging via DevMode (read: in
Java) is going to be what you want.

Re: PasswordTextBox Security

[Chris Conroy]

The PasswordTextBox results in an  element on the
page which is handled by the browser in the same way all other such password
boxes.

And, to be a bit pedantic..If you assume an attacker has access to the
address space of your program, then what would stop him from reading said
characters at the time of password entry? The security issues you should be
worried about are things like cross-site scripting attacks.

Re: app engine with hosted mode

[Chris Conroy]

Make sure you see a ?gwt.codesvr fragment in the URL you are using. It
sounds like you might just be hitting the embedded server--not DevMode. You
need that fragment to tell the plugin in your browser to use DevMode.

Difficulty with GWT Developer Plugin Chrome & Firefox

[Chris Rowland]

I'm doing some work with the most recent version of GWT (have been
working using the old hosted mode for quite a while) and I'm having
issues getting the developer addin installed in Chrome and Firefox.
When pasting the URL provided by the eclipse plugin, IE prompted to
install the addin and it worked ok.

However, when doing the same thing in Chrome and Firefox, it failed.

In Chrome, it simply said the addin was missing.  With Firefox it said
it was missing, but couldn't find it.

I wasn't able to find anywhere to download the installer manually,
either.

Any advice?

Re: GWT 2.1 M3 is now available

That's a great point, and we'll be there with M4. There's a Google snapshot

It's a single repo where we'll upload 2.1-BUILD-SNAPSHOT jars. Once we get
to GA, we'll be in Maven central.

GWT 2.1 M3 is now available

[Chris Ramsdale]

Back in May, at Google IO, we announced an integration between
VMware’s popular Spring framework for server-side development and GWT
for the client-side. Since then we have been excited by the feedback
and comments from customers building real world apps with this
technology. In response to their feedback, and pushing towards
delivering on our our promises form IO, we are very happy to announce
release M3. Looking forward we expect our production quality, GA
(general availability), drop to land in a few months.

Some key features included in this release are built-in history
support in Activities and Places, relationship management within
RequestFactory, and the ability to call instance methods on entities
themselves. The overarching goal was to nail down the API and deliver
on features and functionality that are vital to creating industry-
grade business apps.

For the Spring Roo community, we're continuing to build-out the
integrated stacks that we announced back at Google I/O. GWT 2.1 M3
includes a parallel Roo 1.1 M3 that will allow you to take advantage
of all the features mentioned above. Also, in the spirit of co-
operative and transparent development, you can find a full list of
features and functionality over at Roo's issue tracker.

https://jira.springsource.org/secure/IssueNavigator.jspa?mode=hide&requestId=12001

GWT 2.1 M3 is available on our Google Code download site. We’d love to
hear your feedback and thoughts on the release, and this forum would
be the best place to post this information.

Re: same code -> different compile plattforms -> different results???

[Chris Conroy]

Well, until http://code.google.com/p/google-web-toolkit/source/detail?r=8605
the
compiler could use different line endings which would result in a different
hash for your .cache.html files.

Though, this would not change the appearance of your code. Most likely, you
have your caching mis-configured and in one browser you are seeing a stale
version.

Re: Dev plugin for firefox 3.7

[Chris Conroy]

The short answer is that after preliminary support went in, the supporting
libraries changed upstream. Also, when the prelim support went in Windows
dev libraries weren't even available. I think John has a change in the works
to get this updated but is blocked on something.

I suggest for the time being that you just use production mode for anything
you specifically have to test on 3.7. If that won't work, consider using a
slightly older version of 3.7 (from Jun 16 or so) to build the plugin.

Re: Bug with UI Handler when using Selection Event

[Chris Conroy]

Repeatedly bumping threads like this is rude and is considered spam. Please
do not do it again.

Everyone, please take note that this is not acceptable behavior. If you find
that someone is bumping threads repeatedly, please notify the group
moderators.

Re: Making GWT look good...

Thanks for all of the great feedback (and please, keep it coming). With
these suggestions and some internal guidance, we're going to move on to
fleshing out mocks. Once I have something tangible, I'll share it here.

Making GWT look good...

[Chris Ramsdale]

Hey GWT(ers),

I've heard from many of you that GWT apps simply don't look that good out of
the box, and styling the default app would go a long way. We couldn't agree
more. As some of you know, GWT 2.1 (with the help of Spring Roo 1.1) will
generate a full-fledged scaffolding app that users can then go customize,
and build on top of. The current incarnation looks like this:

http://gwt-bikeshed.appspot.com/Scaffold.html

And while it's a start, it's long from being...well...good looking. I'm
working with some UI/UX people back at Google, but in the spirit of openness
I wanted to get feedback from the real users -- you. Specifically we're
looking for "business" apps that are a good example of UI and/or UX. Apps
that allow you to track tasks, expenses, travel, projects, etc.

If you have ideas, simply post a link in a follow-up to this thread.

Cheers,
-- Chris

Re: Wave Demise.........sad day for GWT

[Chris Ramsdale]

Thanks for all of the responses, even the criticism is highly
beneficial. In regard to the Wave announcement, we're certainly sad,
but do realize that many features (Code Splitting, SOYC, another spin
on MVP+GWT) were born out of the experiment. Where possible, we're
definitely interested in pulling in some of the Wave functionality
into GWT (widgets obviously being top of mind).

Re: Instantiations, we're extremely excited to have the team joining.
Right now, we're heads down integrating the team and the products, but
we'll keep the GWT community posted when we have more information.

Re: Server support for speed traces in GWT 2.1

[Chris Conroy]

Steve,

SpeedTracer and GWT continue to be fully open. For those that use
SpringSource TC, this feature is useful.

Some enterprising folks have started porting this work to other servers:

Re: Possible problem with GWT URL mechanism and cache

[Chris Conroy]

Ittai,

The server bundled with the Eclipse plugin is Jetty, and it should
work correctly out of the box (read: no extra configuration on your
part). Re-reading your original post, it looks like you might think
you are using development mode ("stop the debug") but your URL
indicates you are actually using production mode. Make sure you launch
your development mode session with the ?gwt.codesvr fragment. If you
want to refresh your code without using development mode, you want to
make sure you run a full GWT compile.

Re: Possible problem with GWT URL mechanism and cache

If you use Apache, the following .htaccess should work:


  ExpiresDefault "access"



        ExpiresDefault "now plus 1 year"

Re: Possible problem with GWT URL mechanism and cache

This sounds like you misconfigured your webserver to serve up the
.nocache files as cached.

Re: JAXB & GWT How I can use JAXB generated classes on client side

[chris]

I would love to use gwt-rpc for this application but the server side
is an embedded device with only apache and gsoap. I have done this
once for another embedded system using rocket-gwt json serialization
and wrote a backend cgi exec that would unmarshall using json-c to c
structs. But this has a soap service with over 150 separate soap
calls. I guess I am looking for a way to do xml serialization client
side and that is not going to be possible without writing my own
library. It would probably be possible though with some custom
annotations and deferred binding simlilar to what rocket-gwt does but
I have not found such a library. Maybe I will take a stab at it when I
get some time.

Thanks for the advice,
Chris

There have been some known issues recently with webkit properly reporting
items as coming from cache which in turn affects SpeedTracer. Note that just
because the file is in the cache doesn't mean the browser used the cached
copy. (Cache invalidation != Cache eviction)

If you happen to observe SpeedTracer reporting cache status badly, please
provide your Chrome version and, if possible, a way to reproduce at
http://code.google.com/p/speedtracer/issues/detail?id=19

Re: JAXB & GWT How I can use JAXB generated classes on client side

[chris]

Thank you for the advice and it appears that this would work for
server but not for client marshalling. I have been investigating a way
to use JAXB to marshall soap requests on the client side but have not
found a way as of yet. I would love to get rid of soap all together
but unfortunately that will not be possible. Has anyone found a way to
marshall the POJO to XML on the client?

Thanks,

The regular embedded web server in DevMode is Jetty, and it serves up your
resources (html, css, images, etc..) and handles servlet requests. The code
server is what the dev mode plugin talks to in order to run your GWT code in
the Java VM.

Re: Timeline for support of Firefox (Minefield) 4.0b2pre?

More generally, please run a search on your question before asking it. If
