It may help to try to deploy in a fresh install of Tomcat (downloaded
from apache, the bin distribution) executed with root.

Most Tomcat distributions (specially the one from Debian) are
configured for production mode. It may be really secure, but it's a
nightmare for programmers.

Once you have it running you can try to look for the differences in
the setup and experiment a bit.

 File isn't accessing the file but is the representation of a

  Could this be a GwT running on tomcat and linux issue?

 No. Most likely Tomcat is running as a unprivileged user (like
 nobody) or installed a SecurityManager preventing you from
 accessing parts of the file-system outside the sandbox.

Re: Inheriting a class within a package

Re: Managing of connection to JMS server, listening to JMS Topic

Probably, an even cleaner alternative would be to inject a JMS

 - I assume, it would clean up itself when undeploying, but I'm not

Re: Extracting the year from a Date() object

 I have a Date() object that holds a date of birth and I want to

 that when I try to use a Calendar() object the application doesn't

Sadly, the best method is to use GWT's DateTimeFormat:

private static final DateTimeFormat YEAR_FORMAT =
DateTimeFormat.getFormat();
public static int year(final Date date) {
  return Integer.parseInt(YEAR_FORMAT.format(date));
}

You can put this into a utility class; you might even want to
remove the static modifier on year() and inject the class
where its needed; that might help testing.

Since GWT is being translated to JavaScript, and JS has no
threads, you can leave YEAR_FORMAT static, and you don't
need to synchronize access to it or create one for each
year() call.  Still, since you get the format through a getFormat()
call and not a constructor, I suspect GWT caches DateTimeFormats.
In that case the following is clearer.

public int year(Date date) {
  return
Integer.parseInt(DateTimeFormat.getFormat().format(date));
}

Should we all be using [JG]oda-Time?

Re: seamless rpc during upgrades

2010-06-08 Thread Sripathi Krishnan

*IMHO, once you have deployed new code, you want to tell the users to
refresh the browsers as soon as possible. Trying to get old clients working
with new code can work at times; but since there is no guarantee I prefer to
fail-fast.*
*
*
*re. Old Client, New Server*
I prefer to take a different approach - which is - If the serialization
policy can't be found, *assume* the client is out-of-sync and throw
IncompatibleRemoteServiceException. As a general purpose library, GWT
cannot assume the above statement. For example, developers can forget to
copy the *.rpc files during deployment. But in my case, I know that I will
copy the files and deploy them properly, so at runtime if I can't find the
files, it just means client and server are out of sync.

So, I end up overriding doGetSerializationPolicy() in my RPC Servlet. If
super.doGetSerializationPolicy() returns null, I throw an
IncompatibleRemoteServiceException. The client code handles this exception
and asks the user to reload the browser.

*re. New Client, Old Server*
In this case, client code will get a 404 when trying to load
permutation.cache.html file. It is possible to detect this and take
action. You need to provide an implementation of onLoadErrorFn, and in that
implementation you ask the user to refresh his browser. See this
threadhttp://groups.google.com/group/google-web-toolkit/browse_thread/thread/2dafc6fd50e622a4for
more information on this error function.

Hi,

I've done some research about keeping GWT deployments as seamless as
possible for both new and old clients.

Basically avoiding (when possible) the LegacySerializationPolicy,
IncompatibleRemoteServiceException, type name elision, no RPC
whitelist, etc. errors that I had been seeing while deploying upgrade
to a gwt app.

I had trouble finding an existing writeup that covered everything, so
I wrote up a more detailed description at:

http://www.draconianoverlord.com/2010/07/07/gwt-seamless-upgrades.html

It seems to boil down to:

* Use IsSerializable and no type name elision in the RPC DTOs (can't
rely on serialization policy file being available)
* Handle IncompatibleRemoteServiceException in the RPC AsyncCallbacks
for when the contract has actually changed
* Handle 404’s in the runAsync onFailures
* Minimize/eliminate the window when both old and new servers are
available

I'd appreciate it anyone could verify/correct/add to my list of
suggestions.

When in doubt, I can deploy at night, but I was hoping to gain some
flexibility and just wanted to see what it would take to make it
possible.

Thanks,
Stephen

Re: Extracting the year from a Date() object

2010-06-08 Thread Erik Uzureau

I am curious as to why folks wouldn't just use

date.getYear() + 1900;

There was a post[1] not to long ago that I replied to (inadvertently 3
times) essentially suggesting the above, but nobody followed up so I'm
wondering if I'm not on the right track.

In a nutshell:

1) The GWT date object is based on the js date object
2) The js Date object's getDate(), getYear(), etc  are not deprecated.
3) Official GWT widgets (namely the DatePicker) are using those deprecated
methods

Happy to be proven incorrect, but seems more straightforward to me to use
those methods than to go through a formatter.

Erik

Using jqPlot library (javascript chart) with the MVP pattern

2010-06-08 Thread Rizen

Hello,

I'm creating a chart thanks to the jqplot plugin, which depends of the
JQuery library.
From the jqPlot website I try to implement the simple following
example :

public native void createChart() /*-{
line1 = [1,4,9, 16];
line2 = [25, 12.5, 6.25, 3.125];

plot1 = $.jqplot('chart1', [line1, line2], {
legend:{show:true, location:'ne'},title:'Bar Chart',
series:[
{label:'Profits', renderer:$.jqplot.BarRenderer},
{label:'Expenses', renderer:$.jqplot.BarRenderer}
],
axes:{
xaxis:{renderer:$.jqplot.CategoryAxisRenderer},
yaxis:{min:0}
}
});
}-*/;

Using the MVP pattern, I need to attach this chart in my view. So I
can't use $wnd.$, I have to find another solution.
Maybe I can use the JavaScriptObject class but it's not compatible
with the Widget that I must use with the view.
Do you have an idea about how have I to proceed ?

Thanks a lot for your help.
Regards.

Hook before History changes

Hi, I think that question has been posted before but don't find any
answer for it. I want to have a behavior like this forum, Whenever the
user press back or forward buttons being able to alert the user that
he is going to loose the changes.

The problem come while navigating inside my page. If I hook in the
History.onValueChange the History has already change before I have
some control. So the only way I find is either I let the History in an
inconsistent state. Or I fix the state but loose the future History
(the forward History get resets due the change).

So is there a way I can hook my code before the actual change occurs?

Thanks

GWT and Spring - with Spring Web MVC or without it?

2010-06-08 Thread ezamur

Hi all...

I am new to GWT - had some contact with it earlier but not enough to
say I am confident with it.

My task is to investigate this technology and pair it with Spring
framework. There are a lot of tutorials explaining how this can be
done, but what is bothering me is I can't decide which approach to
choose. For example, I've seen one using Spring's MVC (like this one:
http://technophiliac.wordpress.com/2008/08/24/giving-gwt-a-spring-in-its-step/),
but also other where integration is done without it (e.g.
http://code.google.com/p/gwt-spring-starter-app/)

I am afraid to miss something important by choosing one of these
approaches and possibly lose some of Web MVC functionalities that
might be needed later or end up in dead end street using it.

I would be grateful if anyone explained me what are the pros and cons
of these approaches from practical point of view - is there a need for
DispatcherServlet and Controllers while having GWT and its RPC
mechanism.

Thanks in advance.

1 layout - 3 browsers - 3 results?

Hello,

after struggeling with the positioning of layout panels without a real
solution (thread layout problems with positioning or aligning
content) I found out that things are even worse: There are totally
different results with different browsers:

- Linux + Firefox 3.6.3
- Windows + Firefox 3.5.2
- Windows + IE 7

Look at the screenshots:
http://h1403230.stratoserver.net/apache2-default/tmp/LayoutTest/Screenshots/

The different Firefox versions show the chess board positioned and
aligned differently. And in IE the whole layout is totally broken.

I believe that either
- I made some serious mistakes (I hope so), or
- predictable layouts are not realizable with GWT

I have reduced the code to a minimum. If you like, you can view the
main source files or download the whole eclipse project:

http://h1403230.stratoserver.net/apache2-default/tmp/LayoutTest/

What do you think?

Sorry, I did not realize the fmod's posting at the time of mine.

However, today I found that things are even worse:
The result looks totally different on different browsers (see thread:

If this is true (and I didn't make another mistake) then GWT is not
suitable for doing predictable layouts in my opinion...

 I believe that either
 - I made some serious mistakes (I hope so), or
 - predictable layouts are not realizable with GWT

 I have reduced the code to a minimum. If you like, you can view the
 main source files or download the whole eclipse project:

 What do you think?

Hi,

there is no need to poll.
Use techniques like comet, server push. It is rather simple to

I think your best bet is to use the onResize and just calculate it. CSS

No source code is available error when using resources

2010-06-08 Thread AkiRoss

Hello,
I'm trying to use ClientBundle for icons and Constants for text in my
application, but I get these errors:

[ERROR] Line 133: No source code is available for type
resources.images.IconsBundle; did you forget to inherit a required
module?
[ERROR] Line 134: No source code is available for type
resources.strings.IconsStrings; did you forget to inherit a required
module?

But I included both Resource module and I18N module in my gwt.xml

module rename-to='narrative_ke'
  inherits name='com.google.gwt.user.User'/
  inherits name=com.google.gwt.resources.Resources /
  inherits name=com.google.gwt.i18n.I18N/
  !-- ... Other stuff --
/module

My project has this structure:

myproject package contains client code and so on, in detail
myproject.client.common.widgets contains the lines 133 and 134 that
give the errors above, here the lines:

private IconsBundle images = IconsBundle.RES;
private IconsStrings strings = IconsStrings.RES;

they just use the IconsBundle and IconsString resource instance, that
is:

resources.images.IconsBundle interface is like:

public interface IconsBundle extends ClientBundle {
public static final IconsBundle RES = GWT.create(IconsBundle.class);

@Source(resources/images/someImage.png)
public ImageResource someImage();
}

and
resources.strings.IconsStrings interface is like:

public interface IconsStrings extends Constants {
public static final IconsStrings RES =
GWT.create(IconsStrings.class);
public String someString();
}

Actually I've only one locale, placed in the file
resources/strings/IconStrings.properties

Can somone please tell me why I get these errors? Did I forgot other
modules?
In case it may help, I'm developing with Eclipse on GNU/Linux x86_64.

Thanks

Get all markers added by GeoXmlOverlay.load()

2010-06-08 Thread Jesse Fulton

I'm planning on loading a bunch of markers using the
GeoXmlOverlay.load() method, but I also need to be able to
programmatically access the generated markers after the fact. Is there
any sort of map.getAllMarkers() method that I can call to retrieve the
markers? I haven't been able to find anything yet and I've been
searching for quite a while now...

I'm using the Java libraries: GWT Maps 1.1.0  GWT 2.0.3

GWT, servlet, JSP and datastore

2010-06-08 Thread laurentleb

To the GWT community,

I am pretty new to GWT but familiar with n-tiers application
development. I find GWT fascinating to develop rich web applications
and went through the tutorial. This is amazingly simple to achieve.

On the other side, I tested also Google app Engine to develop and
deploy a JSP/servlet + datastore testing app. Once again, it is really
efficient.

My question is : how can I combine these two approaches to build nice
applications on the client side with efficient business java code on
the server side and data storing in Google datastore ?

Are there some guidelines ? Is there a policy ?

Thank you in advance for your help.

Using GWT in an existing Java Project

2010-06-08 Thread Mike

Hi-

I am trying to create a GWT application that will be stored in a much
larger project (it is the project that contains all the code my
company has developed, so its pretty big). However, eclipse will not
allow me to create a Web Application Project within the existing
project, and all my attempts to move a functional project into our
file structure have failed. Do you have any ideas on how to get GWT to
work within an external project, short of creating my project, and
then trying to import my company's entire code base (~120,000 files)?
Thanks.

I apologize in advance if there has already been a thread pertaining
to this (I looked as best I could).

Thanks

-Mike

GWT-Roo Issue : ClassNotFound Exception while trying mvn gwt:run

Hi All,

I am a newbie in Roo and GWT.

STS Version : 2.3.3.M1-e3.5.2 Win32

I had successfully created the First Project (Roo Standalone) as

generated without any issues.

But as soon as I fire 'mvn gwt:run', I get the

Even after adding the following in pom.xml
--- 'dependency

Setting cell widthheight, while dynamically changing color

2010-06-08 Thread M.qrius

I'm trying to create a table with square cells, which are always the
same size. I'm having some trouble with doing just this.
I've created a
Grid editG = new Grid(5,5);
and I tried to set the width/height of the cells in the css with:
td {
width:50px;
height:50px;
}
But this doesn't actually increase the size much. It definitely
doesn't reach 50x50 px.


Apart from this, I want to dynamically change the background color of
a cell. I did this with:
editG.getCellFormatter().setStyleName(0, 0, alive);
and in the css
.alive {
background-color: #00;
}

This seems to be working.

How do I set the cell size? I feel like I'm missing something obvious.
Could someone point me in the right direction?




NB:The content will not exceed the size, so overflow can be
disregarded.

Returning values from RPC-Call

2010-06-08 Thread uwi_u

Hi there,

I'm currently writing an application which fetches Data from an DB2
Database. I've got a very basic question opn returning values from
RPC


Here's the method, which calls the RPC:
public int loginUser(String user, String passwd, boolean override){
  loginFeedback = -1;
  XGENgwt.loginUser(user, passwd, override, new AsyncCallback(){
public void onSuccess(Object result){
  loginFeedback = Integer.parseInt(result.toString());
}
public void onFailure (Throwable caught){
Window.alert(Unable to login: +caught.toString());
}
  });
  logToServer(Bei der Zuweisung: +loginFeedback);
  return loginFeedback;

Returning values, next try. Sending was too fast for me

2010-06-08 Thread uwi_u

Hi there,

I'm currently writing an Application with GWT, and am Stuck at one
position:

When I call my RPC, the value which is to be returned, will be passed
to an global variable. Unfortunately, the returning of this global
variable out of the method happens before the onSuccess comes
back.

the only way to block which I see is to do a while until 
loginFeedback  0


Heres some Code (loginFeedback shall get a value from 0 to 2):

public int loginUser(String user, String passwd, boolean override){
  loginFeedback = -1;
  XGENgwt.loginUser(user, passwd, override, new AsyncCallback(){
public void onSuccess(Object result){
  loginFeedback = Integer.parseInt(result.toString());
}
public void onFailure (Throwable caught){
  Window.alert(Unable to login: +caught.toString());
}
  });
  logToServer(Bei der Zuweisung: +loginFeedback);
  return loginFeedback;
}

Is there a better way? I hope so

Downloading a document while some RPC call is still running

2010-06-08 Thread Darkman97i

Hi,

Well when I execute some Window.open and there's some RPC still live
always is firing some error
Window.open(http://someweb.com/somedocumentPath, _self, );

I think the problem is that, the browser url is temporary broken by
new url, reason why rpc is closed and error is fired meanwhile browser
not detects that is a file to be downloaded.

Really it's a stupid problem, but I don't find a good and simply idea
to solve it.

1- One solution could be open in a _blank window, but it's really an
horrible usability user interface option ( I think ).
2- Other in the same way than the first could be open some new small
window, and when document is yet started to downloading close it
( I've seen in some webs ).
3- In some cases I can not ensure ( synhronize ) that there's no RPC
call before downloading. That could be a good option, but is not
possible in my case.

Any idea it'll be wellcome.

HttpSession session = getThreadLocalRequest().getSession() Null Pointer Exception

Hello every body,

I can't figure out why there is a Null Pointer Exception here.

I am trying to share informations through sessions within my
application. I have a regular servlet that sets the session and insert
a login. then I wanted to retrieve that login into a
RemoteServiceServlet with that instruction :
HttpSession session = getThreadLocalRequest().getSession();

but as I said it gives me a NPE.  What is wrong?
Also I can't find any good documentation on working with sessions with

Server Side Socket Connection in GWT

2010-06-08 Thread Jay Bruno

Hello All,

I'm trying to set up a GWT Web App that will give a User a certain
Permission in the Web Application based on their Active Directory
Roles.  I'm currently trying to connect to an AD server via LDAP.
This part works perfectly unless I add it to the GWT application.
Then I get a socket error saying that it can't connect.

I have read that you are not able to open Sockets in the App Engine.
Does this still hold true?  If it does that's fine I can run the Web
App on Tomcat.  I just need to know for sure that there is no way to
do the LDAP authentication with App Engine and GWT.  It will be an
effort to change the project over to Tomcat.

Any hints/tips/tricks would be greatly appreciated.

Cheers,
Jay Bruno

Re: 1 layout - 3 browsers - 3 results?

does this mean that I have to do all the layout in absolute

In addition, the layout under IE 7 is totally broken. What is the

predictable results?

However, you did not show us the full code.

 Hi,

 I want to perform a size calculation on a composite generated by
 UiBinder, using UIObject.getOffsetWidth(). The composite's ui.xml
 (simplified) looks like this:

          ui:style
                 .test {
                         width: 80px;
                         height: 50px;
                 }
         /ui:style
         g:HTMLPanel styleName={style.test}
         /g:HTMLPanel

 When I execute getOffsetWidth() during onModuleLoad(), the result is
 987 (the same as the body's width in my case). That's quite
 understandable: I assume, the CSS from the ui.xml isn't applied yet.

 So I put getOffsetWidth() in a DeferredCommand, and now it returns 80,
 which is correct.

 But I'm a bit worried, that this may actually be a race condition: Can
 I be sure, that the CSS will be fully loaded, before the
 DeferredCommand gets its turn? Or is there a better place to put that
 code?

 Thanks
 Chris

Re: Compilation NullPointerException

2010-06-08 Thread Stefan Bachert

Hi Daniel,

we need much more information.
Probably you have a uncommon complex type case.
I run into such a problem when I used foreign code which has
extensively used inner classes and generics.
The solution was, to make some inner classes static which should be
done anyway when possible

Re: layout problems with positioning or aligning content

I would like a menubar, and whenever a menu item is selected, I would
like to show a panel.

The screen should have a north, west, east and south section, and in
the center the current panel should be shown.

For example, if the user selects create account, a form should be
shown to enter the data for a new account.

And I would like the form to be centered within the middle space...

Re: 1 layout - 3 browsers - 3 results?

I'm sure someone will correct me if I'm wrong, but layout panels are more
for using the whole of an area of the screen - header, footer, menu on the
left, all the rest used for page display, that kind of thing rather than
allowing you to float things at various places on the screen.

For that, it seems to work OK in my limited experience.

You can use 'margin:0 auto;' to centre the inner panel horizontally, listen
for resize events, and just set 'top' to half of what is left of the height
after you take away the height of the inner panel.

If you don't want to do that (and don't care what happens if the window is
smaller than the inner panel) then you can use 'top:50%;margin:top:-300px;'
(changing '-300px' to half the height of inner panel + border). It's an old
hack, but it still works.

Re: Calculation of widget size during onModuleLoad() = move to DeferredCommand?

2010-06-08 Thread Chris Lercher

Hi Stefan,

not sure, if it's only the CSS, or the entire UiBinder - but I had
assumed, that it's only the CSS, because the div has the same width as
the body (which makes sense, if the CSS selector of the div doesn't
find its CSS class).

Oh, the code I posted is all there is for this little test project!
(The only thing that was lost somehow on copypaste is the source code
line RootPanel rootPanel = RootPanel.get();) The HTML file is just
the basic template from StockWatcher, with the unnecessary example
content removed from the body tag.

 I usally put elements in a certain environment to measure its real
 size (inclunding border, padding, margin).

Sounds interesting - how do I get that environment?

Cheers
Chris

Re: DialogBox is already shown right after gadget is loaded

2010-06-08 Thread Alex

i get it to work, my previous post i miss out a /ui:UiBinder at the
bottom
!DOCTYPE ui:UiBinder SYSTEM http://dl.google.com/gwt/DTD/xhtml.ent;
ui:UiBinder xmlns:ui=urn:ui:com.google.gwt.uibinder

modal=true
g:captionbCaption/b/g:caption
/g:DialogBox
g:Button ui:field=clickBtnClick Me/g:Button
/g:HTMLPanel
/ui:UiBinder

the fix is to call these right after
initWidget(uiBinder.createAndBindUi(this));
myDialogBox.show();
myDialogBox.hide();
so it wont show right after the gadget is loaded

Can deferred binding do this?

2010-06-08 Thread Kevin Qiu

I'm thinking about using annotation to mark a method that has certain
aspects, and then be processed by the deferred binding, adding necessary
pieces as needed (kinda like a python's method decorator). Here's a example:

class Foo {

  @Logged
  public void bar() {
// do something
  }

}

and when the generator sees @Logged, it adds a call to log the entrance and
exit of the method. I'm wondering if that's possible.

Re: 1 layout - 3 browsers - 3 results?

Thanks, but it doesn't work, at least in one of the three
environments: Linux + Firefox
The inner panel (chess board) is always stretched vertically to fill
the total height of the parent (see screenshot). Your CSS style
changes something, but it's still stretched. I believe that it works
for the other environments...

But what about the differences in the browsers? I thought that GWT
manages them?

Re: Get all markers added by GeoXmlOverlay.load()

2010-06-08 Thread Jesse Fulton

Well, MarkerManager only works if you add the markers to the map
through the MarkerManager class. GeoXmlOverlay.load() adds the markers
directly to the map, so if I want to use MarkerManager, then I'll need
to write my own KML/GeoRSS parser in order to add the markers using
MarkerManager...

Is there any way to get all of the markers *without* using Marker
Manager? Or maybe some way to get the GeoXmlOverlay class to use
MarkerManager...?

Thanks,

Re: Returning values, next try. Sending was too fast for me

2010-06-08 Thread Chad

You don't want to block the UI with a while loop. Instead, consider
creating an interface with a single method:

public interface LoginCallback {
  void onLogin(int feedback);
}

Then, alter your loginUser method to return void and take as an
addition parameter a LoginCallback:

public void loginUser(String user, String passwd, boolean override,
final LoginCallback cb) {
  XGENgwt.loginUser(user, passwd, override, new AsyncCallback() {
public void onSuccess(Object result) {
  cb.onLogin(Integer.parseInt(result.toString()));
}

public void onFailure (Throwable caught) {
  Window.alert(Unable to login: +caught.toString());
}
  });

  logToServer(Bei der Zuweisung: +loginFeedback);
}

You could also call the onLogin from the onFailure if you wanted to.
Or create an addition method in your LoginCallback to call from the
onFailure.

Take the code that currently follows the call to your loginUser method
and move it into the onLogin method of an instance of LoginCallback
that gets passed to the new loginUser method. Think Async! ;-)

HTH,
Chad

 Hi there,

 I'm currently writing an Application with GWT, and am Stuck at one
 position:

 When I call my RPC, the value which is to be returned, will be passed
 to an global variable. Unfortunately, the returning of this global
 variable out of the method happens before the onSuccess comes
 back.

 the only way to block which I see is to do a while until 
 loginFeedback  0

 Heres some Code (loginFeedback shall get a value from 0 to 2):

 public int loginUser(String user, String passwd, boolean override){
           loginFeedback = -1;
           XGENgwt.loginUser(user, passwd, override, new AsyncCallback(){
                 public void onSuccess(Object result){
                   loginFeedback = Integer.parseInt(result.toString());
                 }
                 public void onFailure (Throwable caught){
                   Window.alert(Unable to login: +caught.toString());
                 }
           });
           logToServer(Bei der Zuweisung: +loginFeedback);
           return loginFeedback;
         }

 Is there a better way? I hope so

Re: 1 layout - 3 browsers - 3 results?


 But what about the differences in the browsers? I thought that GWT
 manages them?


If you add your own CSS, it doesn't go around trying to correct it. It's
just what you do in GWT (using the widgets as they are meant to be used - or
rather, as Google use them and not just how you want to use them, not that
you always get told what that is) and then it's pretty much OK.

So this (http://roughian.com/magnus/) looks wrong in Linux/FF? Shame. It
works in Windows IE/Chrome/FF/Safari/Opera - I don't have the ability right
now to test anything else.

BTW, didn't get the screenshot.

Re: Compilation NullPointerException

Yep changing to static solved the problem...thanks!

Hi Daniel,

we need much more information.
Probably you have a uncommon complex type case.
I run into such a problem when I used foreign code which has
extensively used inner classes and generics.
The solution was, to make some inner classes static which should be
done anyway when possible

Re: Downloading a document while some RPC call is still running

2010-06-08 Thread André Moraes

If you don't really need to open a new window to start the download,
you could make a call to the server and fetch the url to de document.
Then simply put this inside a hyperlink on the application or inside a
dialogbox.

Then the user just need to click on the link to download the file.
This don't make the user navigate to another window, if the HTTP
headers defining the mime-type of the document are correct.
There are also another HTTP header which forces the browser to
download the contents of the url instead of display it, but i can't
remember it...

 Hi,

 Well when I execute some Window.open and there's some RPC still live
 always is firing some error
 Window.open(http://someweb.com/somedocumentPath, _self, );

 I think the problem is that, the browser url is temporary broken by
 new url, reason why rpc is closed and error is fired meanwhile browser
 not detects that is a file to be downloaded.

 Really it's a stupid problem, but I don't find a good and simply idea
 to solve it.

 1- One solution could be open in a _blank window, but it's really an
 horrible usability user interface option ( I think ).
 2- Other in the same way than the first could be open some new small
 window, and when document is yet started to downloading close it
 ( I've seen in some webs ).
 3- In some cases I can not ensure ( synhronize ) that there's no RPC
 call before downloading. That could be a good option, but is not
 possible in my case.

 Any idea it'll be wellcome.

CSS theming

2010-06-08 Thread David Grant

Any suggestions on how to do theming, ie. to allow a new theme to be created
in the future as a separate css file that can be switched on/off at runtime.
I also don't want just global CSS though, I want CSS scope as local as
possible but I want to be able to expose some CSS to be themable. Here's my
idea about how to organize our CSS to do this:

1) Shared CSS file - contain some styles that are shared across all widgets
like fonts
2) Local CSS stuff - stuff that applies only to 1 widget or so, this will be
inside the widget's ui.xml file, or in a separate css file and referened
from the ui.xml file
3) Theme CSS file - there will be several, all of which extend from some
interface that defines classes that can be then modified by a theme's css
file

So within any one ui.xml file I might be referring to some local css, the
shared css, or the theme's css.

Any comments?

GWT api for access of calendar data

2010-06-08 Thread Robo

Hi,
Is anyone else having problems with the GWT  API for accessing
Calendar data. I have been getting
An error occurred while retrieving the Event feed: response timed
out error message
and the
http://gwt-gdata.appspot.com/samples/v2.2.1/HelloGData.html
example is getting the same errors.

Customer support says it is an engineering problem, but it is
definitely a problem for me too.

It looks like this has been going on for approximately 4 weeks? If
anyone has work around idea, please let me know. This killing our
business plan and we had hoped to be helping damaged soldiers and
civilians by now. ouc.

Extending a Widget subclass or Composite?

Adding event handler to the document

2010-06-08 Thread Raziel

What's the best way to add an event handler (for example for keyboard
events) to the entire document?

I need something more general than the FocusPanel; specially because
I cannot attach a FocusPanel to my application's body.

I've seen some solutions sinking events and using
addNativePreviewHandler but it seems kinda overly complicated for
something that should probably be no more than a line of code. Then
there's also warnings like Please note that nondeterministic behavior
will result if more than one GWT application registers preview
handlers. See issue 3892 for details. that tell me I should be extra
careful with this.

Thanks

Get today's date, and the first day of this week's date?

2010-06-08 Thread spierce7

Hey guys, I just found out that the Java Calendar class isn't
compatible with GWT (Assumed it was since Date was). I'm a Java newb
and spent a few hours figuring out how to do what I wanted to do with
the Calendar class, and I'm clueless how to do this with GWT, so any
help would be appreciated.

1. Get today's date.
2. Using the current date, get the date of the first day of the week
(Sunday), and I think I might need to know how to get the end date
also.
3. How to Add and subtract a number of days to a date.
4. I need to know how to parse all the above questions information
into a string.

Off the top of my head, that's what I'm trying to do. 1 More question:
5. Would it improve performance while handling a start date and an end
date for an event, instead of keeping an end date, calculating the
duration that the event would last, rather than calculating the date?
Would it even be worth it? (A friend recommended this)

6. Are we seeing any updates coming for working with dates? I'm
currently using GWT 2.03.

Re: Extending a Widget subclass or Composite?

No.

Ask yourself if you want to expose all the top-level widget's methods. If
you don't, then use a composite. For example, if you are making a labelled
textbox by adding a label and a text box to a VerticalPanel, do you really
want the user able to add more things to the VP, to be able to clear the
widgets out of it etc? If you are making a NumbersOnlyTextBox out of a
textbox, you probably *do* want to expose all the normal methods.

[Development mode] script tag not in top level frame

2010-06-08 Thread Thiago F. G. Albuquerque

Hi,

Development mode does not work if the script tag is not in the top
level frame:

script type=text/javascript language=javascript
src=xxx.nocache.js/script

This is a problem for me, because I maintain an application that uses
a framework (Echo 1) that doesn't allow modifying the top-level frame.
(Believe me, I tried. There's no way unless I modify the framework
itself). Does anybody know how could I work around this?

TIA,
Thiago
