Take a look here for source code for the basic HelloWorld example:

I used that as an example to follow while building my application.

Re: Can't deploy my project anymore

2013-05-22 Thread Jeff Smith

I ran into the same problem and could not figure out which configuration
setting got hosed. Fortunately for me, I had a backup on another computer
and just reverted back to that project and GWT 2.5.

That is one of the drawbacks of GWT--there is too much magic going on
behind the scenes spread out in many directories and files. I will never
try upgrading to a new version of GWT without backing up everything first.

Sorry this probably won't help you--I feel your pain.

Best,
Jeff

Re: Can't deploy my project anymore

2013-05-22 Thread Jack Gage

Has anyone pinpointed the cause of this?

I have tried to fix this with fresh installations of Eclipse Juno and 
Indigo with the GWT SDK and Designer plugins, have deleted the gwt-cache 
dirs, am using jre6, and yet the problem persists, very weird.  What else 
bothers me about this is that I can't figure out what I did that made this 
start happening; from my perspective this functionality was working just 
fine and then started failing one day when I did not make any substantial 
(from my perspective) changes to my environment.

Maybe next I should try to print out all my code on paper, buy a new 
computer, install and setup everything, and type in the code again.

Thanks!

show selected items after filter

2013-05-22 Thread Rauel

the 2 items selected before the filtering are not shown (as selected) in 
the ListGrid. So the user gets confused because he doesn't know that they 
are saved externally, so I would like to check them again for him. So that 
his view is consistent to what he already checked.

I found the forum a way, I write "addDataArrivedHandler" but how could I do 
this? has anyone ever done this and could help me?

Follow my code

private static ListGrid criaGradeAuxiliares() {
final ListGrid gridAuxiliares = new ListGrid();

gridAuxiliares.setDataSource(DataSource.get(Constantes.DS_USUARIO));
//gridAuxiliares.setAutoFetchData(true);
gridAuxiliares.setFetchOperation("usuariosFiscalizacao");
ListGridField colunaNome = 
FabricaComponentes.criaListGridField(new ConfigListGridField().setNome("nome"));
ListGridField colunaPerfil = 
FabricaComponentes.criaListGridField(new 
ConfigListGridField().setNome("perfil"));
ListGridField colunaUF = 
FabricaComponentes.criaListGridField(new 
ConfigListGridField().setNome("siglaEstado"));
ListGridField colunaEmpresa = 
FabricaComponentes.criaListGridField(new 
ConfigListGridField().setNome("empresaFiscalizadora"));
gridAuxiliares.setWidth100();
gridAuxiliares.setHeight(300);
gridAuxiliares.setFields(colunaNome, colunaPerfil, colunaUF, 
colunaEmpresa);
gridAuxiliares.setSelectionType(SelectionStyle.SIMPLE);

Re: Exception reporting is broken in GWT: would you support a kickstarter project to fix it?

2013-05-22 Thread Alex Epshteyn

Correction: when I said that a browser needs to support sourcemaps to
generate accurate stack traces, that wasn't entirely accurate.  What a
browser needs to support is the "stack" property of exception objects,
which provides a JavaScript stack trace with both line and column numbers.
 It's the GWT compiler that uses a sourcemap to derive original Java line
numbers and filenames from the browser-provided line and column numbers.
 This functionality is currently broken in GWT, however, and Chrome is
currently the only browser that provides column numbers.  And even if more
browsers add column info in the future, it's almost certain that their
stack trace formats will all be different, so we'll have to patch GWT every
time a new browser adds the support.  My proposed project will leave us in
good shape to be able to do that easily.

2013-05-22 Thread Alex Epshteyn

Thanks for your comment.  Let me respond to your points:

1) I've seen this point discussed before, and the standard counter-argument
is that the spirit of OSS is free as in "freedom," not "beer."  Lots of
developers get paid to work on OSS projects.

2) This is actually one of the reasons I'm thinking about raising funds.  I
am already on the verge of using my patch inside my own GWT-based app, but
if I get some funding I'd be able to justify taking the extra time to make
sure the patch will pass the review process.

3) I must point out that your third argument is not in the spirit of GWT,
which aims to support as many browsers as possible.

As of today, you will not get good stack traces with GWT on any modern
browser, including WebKit.  By "relevant information", I assume you mean
sourcemaps support.  Well, Chrome is the only browser that currently
supports sourcemaps but GWT's existing support for generating stack traces
with that information is very buggy, and this is one of the things I'm
working on improving.  I'm also not optimistic that sourcemaps will achieve
universal support any time soon, if ever.

Re: Exception reporting is broken in GWT: would you support a kickstarter project to fix it?

2013-05-22 Thread Jens

I dont think you will get paid for it, because:

1.) Its somewhat not in the spirit of open source software
2.) Your patch must go through review and there is no guarantee that it 
will be committed
3.) GWT will remove IE6/7 support soon and probably in 2014 also IE8 
support. Also Opera moves to WebKit. That means that there is probably no 
need for StackTrace emulation anymore in the near future as modern browsers 
provide the relevant information.

Exception reporting is broken in GWT: would you support a kickstarter project to fix it?

2013-05-22 Thread Alex Epshteyn

One of the big problems with deployed GWT apps has always been the
impossibility of tracing JavaScript exceptions back to the Java source
code.  What we need is a true equivalent of Java stack traces.

There was an effort made by the GWT team a couple years ago to solve
this problem ( 
https://code.google.com/p/google-web-toolkit/wiki/WebModeExceptions
), and it was a good start, but unfortunately they gave up without
producing an adequate solution. If you've ever tried to use the
compiler.emulatedStack.recordLineNumbers setting, you know that it is
badly broken: the line numbers and file names reported in the stack
traces are incorrect most of the time, while the the resulting
compiled JavaScript is 70-90% larger than the original.  The way this
feature is currently implemented, the compiler puts instrumentations
in the wrong places most of the time, doesn't do enough to optimize
for code size, and does not provide enough information via symbol maps
for StackTraceDeobfuscator.  On Chrome, theoretically we could use
compiler.useSourceMaps instead, but that feature is badly broken too.

I have spent the last 2 months working on this problem full time, and
I almost have the perfect solution ready.  But I'm an indie developer,
and I can't really afford to go unpaid much longer, because I've
already put business aside for two months to work on this (originally
I thought it would take a week, but I kept finding more and more bugs
and tricky problems to solve, which is why I'm guessing the original
developers gave up on seeing this project through to fruition).

If I started a crowdfunding campaign to help me fund this work to
completion, would you or your employer be willing to contribute?  The
original Google Atlanta team did an amazing job developing GWT for 10+
years, but those guys are all gone, and Google has not had a dedicated
team working on GWT since last summer, so I think it will be up to the
user community to fund its future development from now on.

My goal is perfect JavaScript stack traces with exact Java line
numbers, with only a 50-60% output size increase and similar
performance metrics.  For browsers that support sourcemaps (only
Chrome for now), there will be no output size increase at all, because
I intend to fix all the bugs associated with the
compiler.useSourceMaps feature as well.

Re: drag and drop group

2013-05-22 Thread bhomass

conceptually, of course that is what you want to do. I tried disallow the 
drop from inside the onDragEnter and onDragOver events, but don't see any 
api to set the drag icon to disabled mode. I played 
with event.getDataTransfer().setDragImage(...), but it has no effect.

Re: Creating clickable links within text

2013-05-22 Thread Joel

Thanks for the response. I made some progress, like you say the trick is 
mostly in processing the DOM in the onBrowserEvent. I also had the issue of 
the pointer/selection trying to be handled by the CellList, this requires 
un-styling it appropriately and turning off selection mode:

cellList.setSelectionModel(new NoSelectionModel(),

DefaultSelectionEventManager.createWhitelistManager());

Propagating the click events will be a little interesting as well as 
conditionally constructing these links in the cell renderer, but the end 
state is in sight.

Thanks!,
J

primer for mobile development

2013-05-22 Thread mike b

The company I work for just got a secure mobile app that has browser 
integration for the specific platform (iOS,android). 

We have an existing GWT app (several actually) that could have some 
convenient mobile features. 

Can someone provide direction on resources (articles, books, blogs, forum 
posts) that I should read in order to get started on the right track.  

So, I've been using GWT for 2.5 years now and am very familiar with that. 
 I've read about phonegap and the associated GWT projects around it.  

https://code.google.com/p/gwt-phonegap/
http://www.m-gwt.com/

What else??

My biggest question is:  
How to setup a browser environment to test chrome and safari (iOS) ?  

I will most likely never have the ability to actually have a Mac or iPad 
and will have to test on my personal iPhone. (argh)


Thanks in advance!

Build tree table with GWT CellTableBuilder

2013-05-22 Thread jaga

Hi, I managed this. I followed the example given on the latest GWT showcase for 
the custom data grid 
http://gwt.googleusercontent.com/samples/Showcase/Showcase.html#!CwCellTable

Key is new TableRowBuilder. You can inject rows into the table. Use a Click 
event on a cell to trigger the injection. I used an asynchronous callback to 
get the data and found it easier to redraw the entire table. In the example the 
objects already contain the data. He iterates through a list building a new row 
for each item.

Build tree table with GWT CellTableBuilder

2013-05-22 Thread Ben



Is it possible to build a tree table like 
thiswith the new 
CellTableBuilder of "vanilla" GWT?

The GWT Showcase 
example
 only 
allows to expand the "top level" rows. My use case requires expansion of 
multiple row levels.

How can I achieve this with pure GWT?

This is strange 'cause I tested it as I was replying, with a freshly 
created "modular-webapp" project. I had an error about 
test-client/target/test-client-1.0.0-SNAPSHOT not existing, but that was 
because I hadn't previously "mvn package" (or even run "mvn tomcat7:run"). 
I deleted the launch config and started again (Debug As…) and it just 
worked.

That's generally what I do, as I like to have control.

With this "Debug As… → Web Application (running on an external server)" on

 You're not reaching the appropriate group ;-)

 I suppose you're using AppEngine (form what I know of JPA, I can't see 
 a reason for that kind of message, unless you're using JPA on AppEngine), 
 in which case you can ask for support on StackOverflow: https://**
 developers.google.com/**appengine/community

Make a custom Cell: 
http://www.gwtproject.org/doc/latest/DevGuideUiCustomCells.html
 and 
http://google-web-toolkit.googlecode.com/svn/javadoc/latest/com/google/gwt/cell/client/AbstractCell.html
Your "links" will be s with specific class names, and in 
onBrowserEvent you'll check whether the event target is on of those spans 
and take action accordingly. Using UiRenderer will make it easier if you 
can use it: 
http://www.gwtproject.org/doc/latest/DevGuideUiBinder.html#Rendering_HTML_for_Cells

2) Is InlineLabel really the appropriate widget to use (I just want to take

No, just like any widget. You use Cells, so you can't use widgets (within 
them).
