I am using GWT 2.0 on eclipse plugin.

I need to test two or more applications simultaneously in eclipse.

However, when I start the second app, the GWT Development notification
window says  ... failed to open port 9997  Should I ignore this
error msg?

How should I test two or more apps simultaneously? Is port 9997 hard-
coded as the gwt-hosted server port, so that GWT, by design, croaks
when testing more than one app simultaneously.

This question, I think, should be related to:

Re: GWT 2.0 port 9997 - testing two apps simultaneously

Go into your project settings and tick the box labelled something like find 
available port or enter a different port for one of your apps.

I don't the answer above applies because ...

This is not about the application context port which I set differently
for all my apps: 8090, 8091, 8092, ...
This question is about the gwt-hosted server port which defaults (or
hard-coded) to 9997.

Re: GWT 2.0 port 9997 - testing two apps simultaneously

Never mind!
I found the answer.

Placing
-codeServerPort 9998

in program arguments text box
in arguments tab
of eclipse run configuration

would set the codeServer Port to 9998,
or whichever port I choose.

Cache file is 3 MB!!

2009-12-27 Thread moejo

Hi,

My team has been developing an application in GWT and we are
constantly having issues with the size of the GWT cache.html file.
Our current file size is at 3.3 MB which is huge!

Compared to some of the file sizes I've seen in the forums (50kb,
500kb, etc), I'm wondering if maybe there is something we've missed
completely which has resulted in bad performance.  Can anyone assist
in this?

I've already read the forums and i know we can reduce the size of the
file to around 500kb using gunzip, however, I feel this should be used
as a final fix.  What I'm trying to find is the source of the huge
size in the first place so as to avoid it in future.

Has anyone had a huge file like this before, any suggestions?

FYI - we are using GWT 1.7, compiling for all browsers and are using
SmartGWT (solely for the calendar component).  I've removed SmartGWT
to test and retried it, we still ended up with the same file size.

Any help would be appreciated.

You might consider to upgrade to GWT 2.0 to take advantage of the
guided code split feature, it might not reduce the size of you code,
in fact it'll probably make the total size larger, but the user won't
have to download your application all at once, so they'll enjoy a much
faster start up time. Also, with GWT2.0's SYOC feature, you'll see
exact what makes up of your 3.3MB, so you can work on them
accordingly.

Also, this might be trivial, but I thought I might also ask, are you
using obfuscated mode?

Hi Joe

Thanks for the info, I'll see what effect upgrading to GWT 2.0 has - I
hadn't heard of the SYOC feature, so that definitely might come in
handy.  Only thing is though, we're very close to go-live so I'm a
little hesitant to upgrade at this time, in case there turns out to be
compatibility issues among other things.

Yeah I've got the flag for obfuscated on for the compiler (even though
i know it's by default).

 -- Joe


I hadn't got much trouble upgrading to GWT 2.0 myself, but then again,
I can't speak for everybody. One strategy you might consider is: still
use GWT 1.7 when you release, but just compile with 2.0 during testing
to see what the heavy-weight components are, and try to optimize
those.

Personally, I think you should consider 2.0, not only the SOYC
feature, the new development also makes developing and testing much
easier.

Re: Use smartgwt or not

2009-12-27 Thread maku

@Yozons Support

GXT is not a wrapper of ExtJs. So you can not compare the current GXT
version with any of the existing extJS versions.

They try to produce an almost identically looking end product (extjs
vs. GXT). But the way how this is achived is technically different
(and also from a functional point of view)

On 26 Dez., 21:47, Yozons Support on Gmail yoz...@gmail.com wrote:
 We'll investigate GXT as well.  I have to say that the licensing is more
 straightforward with GXT because the free/commercial tiers are not related
 to functionality in GXT versus SGWT.  But if you go want OSS in a commercial
 product (cheap?), you'd need to stick with LGPL of SGWT over the GPL of GXT.

 But once you go commercial licensing, GXT looks more straightforward.

 How is GXT in terms of ease of data source integration with Java backends?

 Not sure too that GXT is on version 2 while ExtJS is version 3.  Does the
 latest GXT include the latest of ExtJS under the hood?  I suppose I can
 check on their web forums for such details.

 But as a GWT developer, it makes sense to look at both if you need more
 robust widgets.

 So, after populating I try to use it, but it is empty. But, If I use
 Window.alert(something) before, I'll receive in this variable what I
 want.

 For example, this part of code write to GWT.log:

 int statusesSize = statuses.size();
 GWT.log(statusesSize:  + statusesSize, null);
 Window.alert( + statusesSize);
 int statusesSize2 = statuses.size();
 GWT.log(statusesSize2:  + statusesSize2, null);

 12:58:49.864 [INFO] [mythirdgwt2] statusesSize2: 4

 Why it happens? How can I fix it?

Re: Why History.newItem() always calls the onModuleLoad?

2009-12-27 Thread Thomas Broyer



On 24 déc, 06:32, compuroad wilson.ferreira...@gmail.com wrote:
 I thought History.newItem() would only build the history stack.
 However in my App it fires the EntryPoint onModuleLoad, restarting the
 application.

 What am I missing?

Are you only experiencing this behavior in IE? or in other browsers
too?

There's a workaround for some weird behavior in IE that sometimes
reloads the app, and I suspect your call to
History.fireCurrentHistoryState() just after History.newItem(...) to
trigger it.

And actually, I don't understand those two lines: newItem() will fire
the event (unless you already are on the given token, obviously, as it
would then not result in a ValueChange), so why do you need
fireCurrentHistoryState? Can't you, either:
 - call newItem(page, false) to only fire the event from
fireCurrentHistoryState
 - or (I like this better and it is known to work): compare the
current token (History.getToken()) with the value you want to set and
choose whether to call newItem() or fireCurrentHistoryState based on
it?

Well, actually, having built an app this way, I now believe using
history change events as the navigation mean within the app isn't the
best approach. Our new app now fires internal events
(PlaceChangeEvent, to follow the convention settled by Ray Ryan's
talk at Google I/O 2009) which in the end cal newItem(..., false) to
synch the history token with the application's state (and when an
history state change event fires, due to an external action, we
synthesize a PlaceChangeEvent too, so the app can then synch with
the token; it'll result in a newItem(..., false) call in the end,
which will then be a no-op, and all is fine). My 2 c€nts.

Thanks.  I just read about that, which means it should be even easier to

admittedly very little.  I'm most interested in the DTO issue and if there
are good ways to send HashMaps and the like to avoid creating so many of
them, or whether the benefits of DTOs outweigh it with the stronger and
simpler typing.

What size the images are meant to be

To me it is not obvious from the Docs. But of course I am new at this
and am probably not looking in the right places.

I really liked the example of the tab bar on Ian's website (as shown
below) but I could not find any CSS code of the how the images were
used to make it look different.

Any help would be greatly appreciated.

Thanks Team.
Merry Christmas.

Re: Use smartgwt or not

There are a few strategies for DTO and GXT. Here are two

http://www.extjs.com/helpcenter/index.jsp?topic=/com.extjs.gxt.help/html/tutorials/beanmodel.html

I also did some using Commons::BeanUtils to autopopulate a DTO since I
use Cayenne on the backend and it was not serializing very cleanly.

So far I've found GXT to be pretty good to use although DataGrids have
been, and continue to be, somewhat of a nightmare for me but I'll find
my way through. GXT + Instantions WindowBuilder or GXT have made
things mostly great on my current project.

Hosted mode stops working for a specific package

Odd problem. I've been working on an app for a few weeks and recently
had some disk space issues that caused random eclipse crashing etc.

Now that those are fix my project no longer will launch in Hosted
mode, but only if I am specifically using the package com.pgi.gwt with
an entrypoint of PrintGate.html (my application package and entry
point that worked before I started having trouble).

Any -new- or existing GWT app I create with those parameters gives me
this warning:
[WARN] Confirmation was required to visit untrusted URL:
'http://gwt.google.com/missing-plugin

Any new or existing app -without- these parameters loads up fine.

Any tips? What painfully obvious thing am I missing here and why does
it only exhibit this behavior for this specific package/entry point
combination? Is there a cache somewhere its picking up?

FW: problem compiling gwt 2.0 using ant

I'm facing a curious problem when compiling my gwt projects to javascript

Re: Use smartgwt or not

2009-12-27 Thread Tom Schindl

Just to mention that there are other Widget-Projects besides SmartGWT
and GXT. I'm working
on a library called QxWT [1] which works similar to SmartGWT by
wrapping an JavaScript-Library.

We are (yet) not at the point where GXT and SmartGWT are but we are
working hard on to get there. For me
and probably others the main interesting things the license all this
work is available which is in this case LGPL and EPL.

In the next few days we are going to release a small bugfix release
and the next release will hold support for
optimizing the native library code by leveraging the tooling support
we get from our upstream library
(scheduled for first 1-2 months 2010).

In alignment with QxWT release in Q1 there's going to be an release of
an MVP-Library which has highlevel support for Databinding
(to fairly any Domain-Technology you can think of by leveraging the
Eclipse-Databinding-Framework) and other well known
Eclipse Technologies like JFace-Viewers.

close event

2009-12-27 Thread Pablo Martin Gore

Hi
 I have a situation , the cookie is created when the user is login into the
application and we want to remove the cookie when the user press the logout
button or close the browser.

I register the close event like this :

Window.addCloseHandler(new CloseHandlerWindow() {
@Override
public void onClose(CloseEventWindow arg0) {
//clear history token before close the browser
History.newItem();
}
});


But here , the problem is when we press the reload button or F5 , gwt enter
in the event close.
That behaviour is ok ??

Re: Use smartgwt or not

2009-12-27 Thread Martin Kraus

Great - Yozons is already a confused person incapable of making any decision
by himself for *his* project and now you throw in another variable. I
suspect this might throw him in a further endless loop. Oh, btw there's also
gwt-mosaic and Vaadin. Make sure you evaluate those too and good luck trying
to understand Vaadin's server side GWT rendering - not that I'm suggesting
its good / bad.

Anyone who thinks GXT license / commercial model is straightforward is
either uninformed or disillusioned. I'll just repeat what I've said earlier.

Ext / GXT / Ext GWT have and continue to have a very deceptive licensing
scheme. It's licensed under GPL so you cannot use it commercially unless you
are will to open source you client source code *and* your server side source
code according to their very terms of use - which is very bizarre. Secondly
even if you do end up buying a commercial license at $329 / license, you
still do not have access to the bug fix releases.

The $329 / license really doesn't get you much. Version 2.0 final of ExtGWT
was pretty much demoware with over 100 critical bugs. 4 - 6 months later
several bugs have been fixed but license holders are not
entitled to the latest bug fix release of 2.0.3. You not only need a license
but you need a support subscription to download the latest stable version.

See http://www.extjs.com/products/gxt/download.php
http://www.extjs.com/forum/showthread.php?p=393316#post393316

So the real cost of the license is $629 / license / year. In addition to
this be prepared to pay frequent upgrade fees for no good reason. Users were
required to buy upgrade licenses within less than a year of
the ExtGWT 1.0 release because they did an *internal* refactoring to clean
up the code and not because new features were added to justify the 2.0
release. Ext GWT 2.1 is just out and they are already talking about Ext GWT
3.0 which is essentially clean up of their internal code to support the new
GWT listener API's. What should customers pay an upgrade fee again for
something like this?

A final word of caution - read the terms of their commercial license very
carefully and run it by your legal. It's not your typical commercial license
that you'd expect with a commercial product. They have some really severe
restrictions that might even require you end user / customer to buy a
commercial license of ExtGWT. If after reading their license you still think
its straightforward, then good luck to you.

Re: GWT 2.0: Plugin failed to connect to hosted mode server

I suspect when you were using the ip address rather than localhost, the GWT
Dev Plugin was unable to connect to the GWT code server. As a result it was
not able to load (actually inject) the dynamic portions of your project
(e.g. all of the GWT Java code). This is typically a result of some security
restriction(s) set on your machine.

Hello everybody,

I am new to GWT and need some help. I have recently downloaded GWT 2.0
as an Ecplise plugin + SDK.
Following the Getting started tutorial I have created a new GWT
application project in Eclipse, StockWatcher. I have made no changes
to the generated application.

The application was created successfully, so I tried to run it locally
using Run As - Web Application (with the Google icon). Then I
copied the suggested URL from Development Mode tab and pasted into the
browser (Chrome 4 with GWT extension):
http://localhost:/StockWatcher.html?gwt.codesvr=10.0.0.1:9997

I was expecting to view the default page normally, but it turned out
that only the static elements of the web page (the headline Web
Application Starter Project and label Please enter your name:) were
displayed. After a while, a message box pops up: Plugin failed to
connect to hosted mode server at 10.0.0.1:9997. When I close it I get
a blackened screen with:
GWT Code Server Disconnected
Most likely, you closed GWT development mode. Or you might have lost
network connectivity. To fix this, try restarting GWT Development Mode
and REFRESH this page.

This of course happening each time no matter what I do.

Then I tried to compile the project and go directly to
http://localhost:/StockWatcher.html, without the gwt.codesvr
parameter. It did work, but that means that I can only work by
compiling the code each time I want to test it (and probably can't
debug).

At first I thought this might be a firewall issue (although i'm not
sure that accessing localhost should be a firewall concern), but to be
on the safe side I have opened the ports and 9997. It didn't
help.

Any ideas?

Thanks,

Re: Use smartgwt or not

While the information on this thread has become a bit passionate, it is all
good and relevant information. When building large scale GWT-based apps,
developers typically sketch out the foundation and then immediately start
looking for a good widget add-on. Threads like this can be extremely useful
when deciding which route to go.

That said, I would suggest we take this conversation offline as it has
become a bit personal.

Thanks,

Extending existing classes with UIBuilder

2009-12-27 Thread Barney

If I want to extend the functionality of an existing widget using
code, I have the following two options:

1. Extend the class directly.
2. Extend Composite, include an instance of the base class using
initWidget, and forward any required methods.

Each method has its own merits, depending on the exact requirements.

However, using the UIBuilder approach, I can only seem to do the
second method. The problem with the first appears to be that
createAndBindUi requires an existing class to be passed in, but
returns a new Widget, and the only way to incorporate this is by
method 2.

For example, to create a decorator panel with a caption using the
UIBuilder, I can do the following (method 2):

ui:UiBinder xmlns... 
  g:DecoratorPanel
g:HTMLPanel
  divCaption Here/div
/g:HTMLPanel
  /g:DecoratorPanel
/ui:UiBinder

public class MyPanel extends Composite {
  interface Binder extends UiBinderDecoratorPanel, MyPanel {}
  private static final Binder binder = GWT.create(Binder.class);

  public MyPanel() {
initWidget(binder.createAndBindUi(this));
  }
}

But not by extending the class directly.

Actually, this is not strictly true. Given the same ui.xml file, the
following code does exactly what I want:

public class MyPanel extends DecoratorPanel {
  interface Binder extends UiBinderDecoratorPanel, MyPanel {}
  private static final Binder binder = GWT.create(Binder.class);

  public MyPanel() {
replaceElement(binder.createAndBindUi(this).getElement());
  }
}

But to call replaceElement I have to put my class in the
com.google.gwt.user.client.ui package to access the method (which is
declared with package visibility) and ignore the javadoc warning:

This method exists only to support a specific use-case in Image, and
should not be used by other classes.

Which is obviously not an ideal solution.

Is there any reason replaceElement is restricted? Or any other way
to achieve the same result?

Cheers,

Barney

Re: RemoteDeathError in GWT 2.0 Developer Mode

RemoteDeathError is thrown when the connection to the browser is
closed.  Are you changing the URL in your app?  If you change anything
but the hash portion, it will reload the app which will drop the
devmode connection.

You can try increasing the log level with -logLevel SPAM and see what
the last call was before the connection is lost.l

Re: Why History.newItem() always calls the onModuleLoad?

A couple of points:
 - you don't need to call History.fireCurrentState() after newItem().
 - you are calling newItem() from within the history change handler

A typical history-enabled app will call fireCurrentState in
onModuleLoad, actions that change history state simply call newItem
with the new state and do nothing else.  The onValueChanged handler
then does the work of actuallly changing to respond to the event, that
way it just works when the user users forward/back, bookmarks a
history state, etc.

Building an Embed API with GWT

2009-12-27 Thread Andrew J

I'm asking this question as something of a GWT n00b, hoping this will
be easy to solve.

I'm on a project trying to use GWT 2.0 to build an embed API, similar
to Google Maps or wave. The idea is for the API to be used in a
context similar to the following:

code
html
head
  script src=http://greatapi.com/great_api_1-0.js/ !-- ie. the
bootloader widget.noscript.js file from gwt... --
  script
 var widget;
 function loadit() {
 widget = new Widget(Some init params);
 widget.bind(herewego);
 }
 function showit() {
 widget.show();
 }
  /script
/head
body onload=loadit

We'll embed our widget in this div...
div id=herewego/

button onclick=showit()/Show it/button

/body
/html
/code

So far, we've been able to create the relevant objects and methods and
expose them via the org.timepedia.exporter.client.Exporter library to
achieve the effect we want.

So far, so good. However the problem we run into is that the
bootloader (widget.nocache.js) file, which is called and executed
before loadit() method, calls the MD5.cache file, which contains the
'Exportable' annotations, asynchronously, and as such may be loaded
and parsed AFTER the onload event has fired. This means that often the
widget = new Widget() call, initated by the onLoad event, will fail.

Is there any easy way to ensure that objects available are once the
bootstrap has been downloaded and parsed, OR have some kind of
callback provided so that once the MD5.cache file has been
downloaded, we can continue using the API?

Any suggestions appreciated.

Java Server-side responses to GWT

2009-12-27 Thread ben

Hello there

I'm programming an GWT app on a Apache Tomcat Server, which means that
I use Java for server-side programming. So far so good.

Now I'm wondering how I can transfer the data I gained on the server-
side with Java to the GWT.

For example, I have got a list of image paths like
www.example.com/test.jpg
www.example.com/test2.jpg
...

I want to use these images in the application, as in I have to
transfer the data (urls) from server-side to client-side.

But in what format can I return the data? I mean an ArrayList would be
convenient, or a JSON String. I tried both, but both didn't work out
for me...

Have you got some advice how I can make that happen?
Or how more specifically how I can solve my problem above?

Problem:
I tried to get the hang of JSON.. I couldn't figure out how one can
actually form a JSON String (tried to do so with gson).

My situation in pseudo-code looks like this:
for() {
toMyJSONString.add(url[i]);
}
return MyJSONString;

Goal would be to have MyJSONString in the JSON format like:
{
url1: www.example.com/test.jpg,
...
}

Would be great if you could shed some light... I'm not used to Java
yet... but I'm raring to learn! :)

In case im not clear enough, please let me know!
Thanks a bunch!

Best regards,
Benjamin

Re: Grid cell formatting

2009-12-27 Thread Prakash

Hi,
you can use CSS selectors for applying styles for all cells in a
table.


define a style for your table in css

.myStyleForTable{

// Your table specific style.
}

.myStyleForTable td
{
  align: left;
  valign : top;
}

in your GWT code, apply above defined style to your table.

Grid testGrid = new Grid(rows,cols);
testGrid.setStylePrimaryName(myStyleForTable);

In this way you need not to iterate every cell to apply style.
Hope this helps.

Regards,
Prakash M.

Re: Errors/Typos in GWT Docs

Marty,

Thanks for the suggestions. We'll incorporate them into our next doc
review/update.

Keep 'em coming.

- Chris

On Wed, Dec 23, 2009 at 5:27 PM, Marty Hall javahac...@gmail.com wrote:

I have been in Asia the last month doing training, so this is my first
look at the new (yay!) GWT 2.0 docs. GWT 2.0 looks great, but I did
notice a few small errors in the docs:

http://code.google.com/webtoolkit/gettingstarted.html
=

A) Under Create your first Web application:
create a new application called MyApplication should be create a
new application called MyWebApp. Also, I would suggest also saying
something like if you use the Eclipse plugin described later in this
document, you can also do File New Web Application Project and
then interactively specify a package name.

B) Under Run locally in development mode:
The sentence Since this is your first time hitting the development
mode server... is slightly inaccurate since the real issue is if it
is the first time PER BROWSER. I would suggest something like The
first time you use a browser with the development mode server, it will
prompt... Also, I again suggest that you list the Eclipse Plugin
command for running in development mode (R-click project, Debug As
Web Application).

C) Under Make a few changes:
In the first paragraph, java files should be Java files. Also, the
last part of that same sentence (in the case of this Quick Start...)
does not parse and needs to be reworded. Finally, in the last
sentence, change the colon after Send to a period.

D) Under Setting up an IDE:
Since there is support only for Eclipse, I would change the title to
Using the Eclipse Plugin or Eclipse Support or some such. Also,
there should be a comma after IDE in the first sentence. Also, I'd
insert here a very short summary of what the Eclipse plugin does for
you. I would think the majority of users would use the plugin, but
this document somewhat implies that the command line is the normal
approach and the Eclipse plugin is an afterthought.

http://code.google.com/webtoolkit/doc/latest/ReleaseNotes.html
=

A) Under Bug Fixes:
Issue 1574: #remoteCookie should be #removeCookie. Issue 3102:
#removeHandelr should be #removeHandler, and has be should be has
been. Issue 3903: pages no contain should be something like pages
no longer contain or pages do not contain.

B) Under HtmlUnit and Test Cases:
In second bullet, change continous to continuous.

C) Under Problems?:
Add comma after GWT Developer Forum.

http://code.google.com/eclipse/docs/using_sdks.html
=

A) I would be a bit more clear that you should select Web Toolkit
and point at the new GWT 2.0 installation. For those upgrading from
GWT 1.7, that is the part you have to change. The current screen shots
show only the App Engine part, which does not need to change.

http://code.google.com/webtoolkit/usingeclipse.html
=

A) For those upgrading from GWT 1.x, I would make it a bit more clear
that you have to download GWT 2.0 separately. Previously, downloading
the Eclipse plugin also gave you GWT, with no separate download
required.

B) Under Create a Web Application, change java package to Java
package.

C) Under Run locally in Development Mode, this description of when
you will be prompted for the browser plugin is what I would like to
see under the same heading in
http://code.google.com/webtoolkit/gettingstarted.html.

D) Under Make a Few Changes, change java files to Java files.

I am very pleased to see GWT 2.0 out. Keep up the great work!

GWT Noob: Click Handlers and Grid/Flex Table

2009-12-27 Thread spierce7

Alright, so I am trying for the life of me to understand how to do
this. I'm a GWT noob at the moment, and I'm really struggling to
understand how to fully implement clickhandlers in a grid or flex
table to figure out where they are clicking within the grid.
Apparently from what I can see so far is that individual click
handlers for each location in the grid were not meant to be
implemented. Instead it seems that I can implement a single click
handler for the entire grid, and then somehow using getCellForEvent
(ClickHandler handler) I can figure out where was clicked and then
have it react, but I can't seem to figure out how to implement
getCellForEvent() into my code. Here's what I'm using:

private Grid calendarGrid = new Grid(4,4);
private int cellNum;

public void onModuleLoad() {
// Put some values in the grid cells.
for (int row = 0; row  4; ++row) {
  for (int col = 0; col  4; ++col)
calendarGrid.setText(row, col, ( + row + ,  + col + ));
}
calendarGrid.addClickHandler(new ClickHandler() {
public void onClick(ClickEvent event) {
getCellForEvent(event);
}
});

RootPanel.get().add(calendarGrid);

}

What I'm ultimately trying to do:
I'm trying to make something very similar to what's here:
http://google.latest.gwt-web-calendar.appspot.com/
I need to make a calendar-ish program but have some unique
functionality. Everything will be easy enough, but I need to have an
in-depth understanding of how to manipulate the events on such a
calendar once I have it made. The reason I bring this up, is because I
currently intend to have the calendar aspect just be one big grid, and
act according to clicks and drags. I'm not sure if this is a very
efficient way though, and I can't figure how I would display multiple
events, but once I get that figured out I need to have the events
dragable. That seems manageable on a grid (I think), I'm just not sure
how I would limit events to parts of a grid space.

So my questions:
1. How would I implement getCellForEvent into my above code?

2. Do you think my current idea of how to implement my program idea is
going to be effective? Is there perhaps another way you feel I should
do it?

3. What way would you recommend I handle events within the calendar?
That seems to be the part that I'm having the most difficulty
conceptualizing at the moment.

Thanks in advance!

~Scott

Re: Use smartgwt or not

2009-12-27 Thread Yozons Support on Gmail

@Martin - Why would you want to attack me just because I'm evaluating
toolkits?  I understand our application domain just fine, and we've built
multiple applications in JSP technologies that are in our area of expertise
and have been running a profitable software business for 10 years now.
Apparently you have an innate ability to review toolkits and understand all
of their complexity, options and licensing terms quickly and easily.  You
are very blessed indeed.  The fact that it takes me time to review them
shouldn't mean I'm confused.  It is your attitude that has led me to
reconsider sgwt because why buy a product from people who seem to think its
users are not worthy?

In our case, we expect to license both under AGPL and commercial, so GPL
should be fine as all of our code would be similarly available.  When
selling a commercial license of our product, we can do so assuming we've
also purchased a commercial license of the library for our developers.  So
it should not be a huge issue, but we will review it closely (our lawyers
also must be clueless because they also take time to evaluate, and it's
just words).  As to GXT product capabilities, that is something we'll have
to evaluate, fortunately not worrying about your concern for how long it
takes us to do so.

@Tom, I'll take a look.  I've not heard of even qooxdoo before, but a quick
check shows it's got a lot of stuff in there for a 1.0 release.

Re: Use smartgwt or not

@Martin
Regarding the below, can you point to the section that you read this
from @ http://www.extjs.com/store/extjs/license.php ?

Our reading of the license is that its a standard, straightforward,
developer seat + support model + 'no royalty/source release
requirement' which meshes with how most toolkits are licensed (Qt
etc).

Tx
J

 They have some really severe
 restrictions that might even require you end user / customer to buy a
 commercial license of ExtGWT. If after reading their license you still think
 its straightforward, then good luck to you.

Error running JUnit with GWT and App Engine

2009-12-27 Thread Sekhar

I'm running a JUnit test that causes a persistent write (JPA) with GWT
and App Engine, and the test is failing with the below error. The No
API environment is registered for this thread' error led me to the GAE
JUnit guidelines (http://code.google.com/appengine/docs/java/howto/
unittesting.html), but they apply for a pure GAE situation. How should
we run test cases with GWT when it involves persistent writes on the
local GAE? The tests that only read from the store are working fine,
as are direct access through the GWT front-end.

Re: Stockwatcher -UIBinder

While we'll continue to update all code tutorials to use the latest GWT
features, is there a particular UI section within the Stock Watcher tutorial
that you have questions about?

Re: GWT Noob: Click Handlers and Grid/Flex Table

2009-12-27 Thread spierce7

I finally figured out my own answer to question 1. I had to make an
HTMLTable.Cell object and set it equal to the results of the
getCellForEvent(event), then from there call some functions to get the
cell indexes. I had tried that but forgot to capitalize the C in Cell.
Anyways, I'd still really love input on questions 2 and 3. :-)

 Alright, so I am trying for the life of me to understand how to do
 this. I'm a GWT noob at the moment, and I'm really struggling to
 understand how to fully implement clickhandlers in a grid or flex
 table to figure out where they are clicking within the grid.
 Apparently from what I can see so far is that individual click
 handlers for each location in the grid were not meant to be
 implemented. Instead it seems that I can implement a single click
 handler for the entire grid, and then somehow using getCellForEvent
 (ClickHandler handler) I can figure out where was clicked and then
 have it react, but I can't seem to figure out how to implement
 getCellForEvent() into my code. Here's what I'm using:

 private Grid calendarGrid = new Grid(4,4);
         private int cellNum;

         public void onModuleLoad() {
                 // Put some values in the grid cells.
             for (int row = 0; row  4; ++row) {
               for (int col = 0; col  4; ++col)
                 calendarGrid.setText(row, col, ( + row + ,  + col + ));
             }
             calendarGrid.addClickHandler(new ClickHandler() {
                 public void onClick(ClickEvent event) {
                         getCellForEvent(event);
                 }
             });

             RootPanel.get().add(calendarGrid);

         }

 What I'm ultimately trying to do:
 I'm trying to make something very similar to what's 
 here:http://google.latest.gwt-web-calendar.appspot.com/
 I need to make a calendar-ish program but have some unique
 functionality. Everything will be easy enough, but I need to have an
 in-depth understanding of how to manipulate the events on such a
 calendar once I have it made. The reason I bring this up, is because I
 currently intend to have the calendar aspect just be one big grid, and
 act according to clicks and drags. I'm not sure if this is a very
 efficient way though, and I can't figure how I would display multiple
 events, but once I get that figured out I need to have the events
 dragable. That seems manageable on a grid (I think), I'm just not sure
 how I would limit events to parts of a grid space.

 So my questions:
 1. How would I implement getCellForEvent into my above code?

 2. Do you think my current idea of how to implement my program idea is
 going to be effective? Is there perhaps another way you feel I should
 do it?

 3. What way would you recommend I handle events within the calendar?
 That seems to be the part that I'm having the most difficulty
 conceptualizing at the moment.

 Thanks in advance!
