Re: How to integrate an open source web app into a GWT application

2010-08-09 Thread abhiram wuntakal

Hi,

  I am really not sure if this might be totally wrong. But u can take this
as a suggestion from where you can start the solution. Embed the JSP code in
html and make that part of a html widget. You can place this html widget in
one of the panels. Then u can build any other GWT sub application in the
other sub-panels.

  Not sure if this is exactly right, but I think this shud work..

HTH,
Abhiram

Re: deserialization error when DTO is nested

2010-08-09 Thread George Georgovassilis

I'd normally ask you to the DTO code, but you really should check that
your deployment worked alright. So please check that:

1. your projects is refreshed after the build
2. old deployment is wiped and overwritten with the new one
3. logging is enabled
4. no errors about serialization policy are displayed in the logs

Hope that helps,
G.

 I can leave the nested structure in the DTO class as long as I don't
 actually populate the child list. but as soon as I populate the child

 again, works find in hosted mode, fails in deployed mode if child list

Re: Please help - GWT application will not load in IE!

2010-08-09 Thread Manuel Carrasco Moñino

On Fri, Aug 6, 2010 at 4:40 PM, Xandel xandelf...@gmail.com wrote:
 Hey guys,

 Thanks for your feedback. Trevor, trying the Window.alert() to see if
 even that gets fired off. When I say the app doesn't load up at all I
 mean literally nothing from my application loads up. When I initially
 had it running from withing a div tag deep in the documents body, the
 surrounding images and text etc would load up but my app wouldn't.
 There would just be a white space where the application should be...
 Now that I am literally attaching it to the root panel (directly to
 the body) the site comes up, the title is there but there is just
 white. Looking at the source doesn't show anything resembling my code.

 On that point tho - I would like to note that the html does have some
 extra stuff added in there that I obviously didn't put myself:

 Before the body tag within two script tags is

 function SymError()

 {

  return true;

 }



 window.onerror = SymError;



 var SymRealWinOpen = window.open;



 function SymWinOpen(url, name, attributes)

 {

  return (new Object());

 }



 window.open = SymWinOpen;

 And within the body tag also between two script tags is:

 var SymRealOnLoad;

 var SymRealOnUnload;



 function SymOnUnload()

 {

  window.open = SymWinOpen;

  if(SymRealOnUnload != null)

     SymRealOnUnload();

 }



 function SymOnLoad()

 {

  if(SymRealOnLoad != null)

     SymRealOnLoad();

  window.open = SymRealWinOpen;

  SymRealOnUnload = window.onunload;

  window.onunload = SymOnUnload;

 }



 SymRealOnLoad = window.onload;

 window.onload = SymOnLoad;

 I'm not sure if this helps... This is taking me a while to get right,
 because I am developing on Linux, the process of testing each change
 (as it works perfectly everytime in firefox) is literally - Make the
 change -  Upload the war to my server - Open on my windows box -
 Find the Exception Not Caught cache.html file line number - Add the
 catch block on my linux machine in that file - upload the file -
 Check again on my windows box.

Developing with GWT in linux and debuging in windows is not a pain since 2.0.x.
I use VirtualBox to start many windows machines with different
browsers. Then, I run the app in linux using the google eclipse plugin
and I can debug simultaneously with different version of browsers just
in seconds. You only need to be aware of two things, run the app with
the -bindAddress 0.0.0.0 parameter and know which is the IP of your
linux box.
GWT helps to develop JS apps fast, but you need to setup the
environment correctly to save time, if not you would hate it.

Cheers
-Manolo


 That syntax error is still there - I thought it had gone away but that
 was a caching refreshing mistake on my side. I need to literally
 change the line:

 function Vn(a,b,c){var d;d=Qn++==0;try{return a.apply(b,c)}
 finally{dio((fo(),eo));--Qn}}

 to

 function Vn(a,b,c){var d;d=Qn++==0;try{return a.apply(b,c)}catch(a){}
 finally{dio((fo(),eo));--Qn}}

 to satisfy IE. Once again, if anyone has any ideas on that error I've
 put more details on StackOverflow (the -PRETTY version of the code),
 the link is in the previous messages.

 Sigh, will come back to you regarding the Window.alert() idea to see
 how much of the code is loading. And to spierce7, I think you're right
 - thats the best idea to find the problem, will try that after a few
 attempts at minor changes ;)

 Thanks guys,

 And when you say the site doesn't load up at all do you mean you just

 reason IE is having issues rendering the page I would suggest using
 the developer tools in IE8 and see if there is a problem with your css
 and the way you create the page. I'm guessing it's your css thats
 thats causing issues. When I have issues where things don't look right
 in IE I usually just play around with the styles using the developer
 tools in IE8 until it looks right.

  What I'd recommend is (although it's time consuming), is to comment

  slowly until you get the issue. Try to get it down and figure out

  loading makes me think it might be one of the outside layers, perhaps
  try some inner layers of the GUI and see what works and what doesn't.

  If I got your code, that's what I'd end up doing any ways. Errors like

  isn't a well this works in all the other browsers,

Hi Abhiram,

Thank you very much for your answering!!! but i'm not sure that i
understand your suggestion :(
The application that already exists has a client side(js) and a server
side(java servlets)... So you're suggesting that i should embed the
client(js) part in html and make a html widget?

Canvas object needed - Which library should be used?

2010-08-09 Thread Magnus

Hi,

I would like to do something with canvases, but I found that there
exist different solutions, e. g. GWTCanvas (also in different variants
and names), GWT-Graphics, and so on.

These different approaches with partly unclear progresses prevented me
to start playing around with canvases at all.

Can you recommend me a library that has some chances to continue for a
longer time?

Incubator - GWTCanvas problems with image loading

2010-08-09 Thread kstokes

  I'm using Eclipse on Windows.

  I have added a GWTCanvas to the demo app and am trying to load an
image and display it with code which is
omething like this:

http://code.google.com/p/google-web-toolkit-incubator/wiki/ImageLoader


My problem is that the image only loads and displays if I have a
complete URL like


//  String[] imageUrls = new String[] 
{http://www.knivesplus.com/
media/SC-104OT.jpg};  /* This works fine */
String[] imageUrls = new String[] 
{images/GoogleCode.png};  /*
This does not work. */

However, I have created an 'images' folder in my  war folder in
Eclipse, and the following image in the HTML displays just fine:
   img src=images/GoogleCode.pngimg


  I don't understand why the app has no problem reading the image from
the relative path when displaying the HTML, but cannot find the image
using the ImageLoader class.

  What can I do so that I can add images to my eclipse project which I
can then use with GWTCanvas?

Re: How to build a rules-based form controller for a dyn. form in GWT

2010-08-09 Thread salk31

Hmmm. The Tohu thing any use? Sounds like they are taking a sensible
approach...

Incase not:
 Before GWT consideration, the plan was to store the custom form specs
 in XML or JSON. Now, with GWT-RPC there would be a 3rd option,
 (de)serialized JS objects, right??? -- But XML or the less-verbose
 JSON would also be good for me, e.g. to remain GWT-independent.
 Which serialization tech would you choose for this?
I don't think GWT-RPC would/should change how you transport the data.
XML has better tool support but JSON is very convenient with GWT
(overlay types) and makes
testing easy. Your Java/GWT objects could then be for the client only
so have some behaviour
inside them (good OO?)

 There should be *no* external tools in place; instead, a usual online

 matching, registered presentation rules and triggers their action(s)
 section which again results in *state change(s)* on the available
 form widgets, and which by themselves may again trigger more
 presentation rules, and so on...
This sounds like a sensible approach. I think the big choice is if you
have
lots of classes like EmptyValidator or a XPath or JavaScript based
language.
Same for logic about when a field is shown...
e.g. formItem name=willNotEat
showIf=implicitFormObject.hasAllergies.checked /

 Briefly, what arch would you put in place???  Especially for the
 client-side???
I think what you describe sounds about right for the end user code and
should be doable.
The form designer seems like the complicated bit. Is this for end
users too? You doing
something like a SaaS form designer? So the form designers are end
user/customers too?

 I sincerely hope you've already made some experiences with such a
 scenario and can help me further outlining a practical architecture.
 As stated above, the main problems are (a) the client-side form logic
 instantiation, and (b) how to provide an edit-and-preview mode ui
 for admins (the preview result is the one later recycled/presented
 to the non-admin endusers (customers)). What would an arch for this
 look like???
I have done this before, and at current day job. If you are careful
then the end user part is not too
bad, I think the worry is the admin CRUD. A rough idea of how many man
months you have
to do this would help. Is a big job, so even more reason to look at
tohu.

Hello!

The documentation of HtmlUnit says: The class
com.gargoylesoftware.htmlunit.WebClient is the main starting point.

How can I access it in a GwtTestCase-based test?

Hi,

I am really not sure if this might be totally wrong. But u can take

as a suggestion from where you can start the solution. Embed the JSP code
in
html and make that part of a html widget. You can place this html widget
in
one of the panels. Then u can build any other GWT sub application in the

Not sure if this is exactly right, but I think this shud work..

Re: Date Serialization issues

2010-08-09 Thread Paul Robinson

You can't change the timezone. You can't even create a date on the
client and tell it what timezone it should be in - Javascript does not
provide a way to do this.

If you want dates on the client to appear to be the same time of day and
date as it is on the server, regardless of the client's timezone, and
you are using GWT serialization, then you have two options:
(1) Avoid Date objects in your DTOs, and use some encoding of your own
instead
(2) Modify GWT itself so that its custom serializers for java.util.Date,
java.sql.Date and java.sql.Timestamp serialize the
day/month/year/hour/minute separately instead of storing the time since
1970.

See here for more details:

Re: uibinder and css

You can use the external keyword to say gwt that the class should not be

ui:style

@external myClass;

.myClass {
/* Adds extra css here */
}

/ui:style

2010/8/9 Thomas Van Driessche thomas.van.driessch...@gmail.com

Hi,

I could use this: ui:style field='otherStyle'
src=MyUiOtherStyle.css

But the problem is that the css file is on another server...
We deploy the gwt app on an OC4J server, but the javascript is called
from another html page on another server...
And that html page has a link to a css file that my gwt app should use
to.

So is this possible?

Problem running StockWatcher application given in tutorial

2010-08-09 Thread Heshan Perera

Hi, I'm extremely new to GWT development. When following the the
Google tutorial in starting GWT development, I entered all the code as
given in their example and tried running in development mode to test
if it works. I use Eclipse Galileo.

When I take the URL and paste and run it on the address bar of my web
browser (Google Chrome) I get an error saying Plugin Failed to
Connect to Hosted Mode Server at 127.0.0.1:9997 and it is only that
GWT app that loads when you run for the first time that partially
appears on the screen (The text box to enter the name was missing).

Any help on this matter would be greatly appreciated.

[UIBinder] - Nested Panels

2010-08-09 Thread BenJD

Hi all,

I have recently jumped on the GWT bandwagon and have to say I am a big
fan. It makes developing javascript applications fun again.

I have produced many Flex based projects in the past and have come
accustomed to using MXML markup to declare user interface elements. I
can see that GWT's UIBinder functionality is to GWT what MXML is to
Flex so am very keen on getting my head around how it works.

I am currently working my way through the UIBinder tutorial (http://
code.google.com/webtoolkit/doc/latest/
DevGuideUiBinder.html#Hello_Widget_World) and have a query regarding
using Widgets and nested Panels.

I have implemented the 'Hello Widget World' section of the tutorial
and it works perfectly. However if I modify the
'HelloWidgetWorld.ui.xml' to include a nested vertical panel I find
that the app no longer displays any content. Can anyone see why this
may be the case? Details below:

Step To Reproduce

Replace HelloWidgetWorld.ui.xml with the following XML

ui:UiBinder xmlns:ui='urn:ui:com.google.gwt.uibinder'
xmlns:g='urn:import:com.google.gwt.user.client.ui'

  g:HTMLPanel
g:VerticalPanel
Hello, g:ListBox ui:field='listBox' visibleItemCount='1'/.
/g:VerticalPanel
  /g:HTMLPanel

/ui:UiBinder

Results

After compilation our host page displays a blank screen.

Desired Results

The above code takes the example in the 'Hello Widget World' tutorial
and wraps the components in a nested vertical panel. Ideally both the
HTML Text node and Listbox should now display vertically instead of
horizontally (the default behaviour).

regards
Ben

how to use gwt as an alternative to templates?

2010-08-09 Thread amishera

Hi,

In any Web MVC framework like spring, struts etc where, when a servlet
receives an http request and generate the response by forwarding it to
a template passing a model object, how would I replace the template
thing with the gwt classes. That means say in a spring controller

ModelAndView handleRequestInternal() {
  return new ModelAndView(someJsp);
}

The GWT client class works on a base html and then other things are
filled from onModuleLoad method. Now say I am in my controller's
handleRequestInternal and want to delegate the task of rendering to
gwt. How to combine gwt and spring or any web mvc per se?

Thanks.

GWT Developer Plugin problem: Mandriva 64-bit, Firefox

2010-08-09 Thread Paul Gestwicki

I followed the discussion at
http://groups.google.com/group/google-web-toolkit/browse_thread/thread/9e0c72621846bb45/6be4f19213378cf6,
but making symlinks to libnspr4.so did not work for me on Mandriva 64-
bit, with Firefox.

One difference on Mandriva is that libnspr4.so was in /lib64, not /usr/
lib64. I tried making links to it as libnspr4.so and libnspr4.so.0d
in /lib, /lib64, /usr/lib, and /usr/lib64, but nothing changed the
observed behavior: firefox keeps claiming that it needs the plugin
each time I try to visit 
http://127.0.0.1:/MyApp.html?gwt.codesvr=127.0.0.1:9997.

Anyone have any luck getting a Mandriva set-up working? I'm using
2010.1, in case that is significant. I have tried Firefox both from
rpm and downloaded directly from Mozilla, with no observable
difference.

RegEx

2010-08-09 Thread Dunlord

For a Open Source project I'm working on I needed the
java.util.regex.Matcher (and so the java.util.regex.Pattern) classes,
in the client side. They are not in the GWT JRE emulation library, but
the source code for both classes are published by SUN (I'm not sure if
under the GPL).

So I copy-pasted the source code of both clases (and a bunch of clases
they needed), cleaned them to work in gwt's client side and it all
worked wonderfully.

The question is: SUN's JRE source code licensing allows me to do this
and publish it? And under which license? And as a bonus: What I'm
allowed to do with it (or not allowed to do)?

Thankyou

Re: Making GWT look good...

2010-08-09 Thread martino

While I appreciate the richness of widgets and behaviours offered by
framework like SmartGWT or GXT, I don't particularly like their
windowish look and feel, also I don't think it's a particularly good
idea promoting GWT powerfulness or web application in general by
mimicking desktop application widgets aspect (how many useless web
desktops simulating a windows desktop inside your browser have you
seen?).

I think GWT/Roo should support at least two basic skin: a light theme
with few/no images/resources (http://gwt-bikeshed.appspot.com/
Scaffold.html  isn't a bad start to me!) and maybe an heavier more
appealing one but I think some effort should be done to distinguish
GWT/web applications from desktop app. I would use more/nicer effects
(slide, fade ecc.) to have smoother transitions and/or communicate to
the user that something is happening/has happened (think of mobile
apps also...).

Just my 2 cents

 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.

All the instances of Firefox share a common process area which causes to

for IE too.

Adding Event Handlers on the body element...

2010-08-09 Thread seth.ho...@gmail.com

Hello,

I'm using GWT for 2 years now and i did many great things with it.
However, i'm still looking for how to implements KeyboardHandlers on
the BodyElement.
The only way i found is writing something like this in the HTML file :

  body onkeypress=return keyPress(event); onkeydown=return
keyDown(event); onkeyup=return keyUp(event);

And something like that in the EntryPoint

public void onModuleLoad() {
// publish();
}
private native final void publish() /*-{
$wnd[keyPress] = function(event) {
@webapp.client.Application::keyPress(Lcom/google/gwt/dom/client/
NativeEvent;)(event);
}
$wnd[keyUp] = function(event) {
@webapp.client.Application::keyUp(Lcom/google/gwt/dom/client/
NativeEvent;)(event);
}
$wnd[keyDown] = function(event) {
@webapp.client.Application::keyDown(Lcom/google/gwt/dom/client/
NativeEvent;)(event);
}
}-*/;

But i'm really not satisfied with that solution.
Any ideas please ?

Cell click events for incubator's FixedWidthGrid

2010-08-09 Thread Strannik

Hello,

Does anyone know how to figure out which cell was clicked on in the
FixedWidthGrid from the gwt incubator?

Using grid.addTableListener(...) seems to be deprecated a while ago
and does nothing (it probably worked in pre gwt-1.6).

The GWT API reccomends to use:
HTMLTable.getCellForEvent(com.google.gwt.event.dom.client.ClickEvent)

however the incubator FixedWidthGrid extends it's own HTMLTable which
does not even support adding click handlers.

It is still possible to use .addRowSelectionHandler(..) though that
does not appear to tell you which cell on a row was clicked.

Thank you

and navigation - 
http://code.google.com/webtoolkit/articles/mvp-architecture.html#history

This link gives more detail on the History concept -
http://code.google.com/webtoolkit/doc/latest/DevGuideCodingBasicsHistory.html

This link describes how GWT-Presenter manages Place -
http://code.google.com/p/gwt-presenter/wiki/GettingStarted#The_Presenter


My question...

Does anyone know if and how the 2 concepts (History and Place) will
come together? With the existence of Place, is anyone even using the
History concept anymore?

I ask because I plane on using the AppController concept described in
the first link, but I'd like merge this with the Place implementation
I see in GWT-Presenter.

Wondering what the general consensus on this is, if one exists.

bug in Animation class

2010-08-09 Thread Michael

Hi,

I didn't see a place to post bugs, so I am submitting it to the group.

I've been working with GWT for a one off project on our website,
www.studyisland.com. I was attempting to use the Animation class (in
package com.google.gwt.animation.client) and could not figure out a
way to get an animation of an Image object to replay when I clicked on
it. I tried both rerunning the original Animation instance recreating
the instance and attempting to run it. My code is identical to the
example in the GWT showcase, with the exception that I create 3 unique
animations, one for each image on the page.

The showcase animation can be replayed, but in my case, where 3
animations existed the animations could not.

Digging into the Animation class, it is obvious why this is by the
line of code in the method run(int duration, double startTime):

// Restart the timer if there is the only animation
if (animations.size() == 1) {
  animationTimer.schedule(DEFAULT_FRAME_DELAY);
}

So, you can't re-run an animation if you create more than one
animation instance on your page. Thats fine, there may be some
limitation that I'm unaware of to prevent this. I'll just reset the
Animation class back to its initial state and start over... but I
can't because the animations are driven by an array called
animations that is a private static member of the class, and there
are no accessible methods to reset it.

Fortunately the easy solution for me is to just copy all of the code
in the Animation class into a new class, and add a method
resetAnimations to take care of this.

public static void resetAnimations() {
  animations.clear();
  animations = null;
}

I just call this before re-running any animations, and everything
works fine.

Now, I consider myself pretty good with Java, but I'm not a javascript
expert so I can't say for sure whether doing this is safe or why the
original programmers didnt include this functionality initially.
However, I think it very likely that there will be other GWT users in
the future who might encounter this issue, hence I think it should be
addressed.

If you have any questions about my writeup here, or would like some
code or something like that, feel free to email me:
michael.vill...@gmail.com.

I'm loving GWT by the way. Thanks to everyone who has contributed!
-Michael

Script tag dynamic loading

2010-08-09 Thread Vincent COROLLEUR

Hello,

I'am trying to load dynamically with GWT some scripts in order to use
google map API V2.

By the static way it works (script tag in the index.jsp page) :

script src=http://maps.google.com/maps?
file=apiamp;v=2amp;sensor=true_or_falseamp;key=ABQIpOR5tulUc5y1R6lOKFkbpRTwM0brOpm-
All5BF6PoaKBxRWWERTqbaRJ6lpQdSlaltvv3tD-fLXwvQ type=text/
javascript/script


I tried this to do it dynamically (from the EntryPoint) but it doesn't
work :

Element script1 = DOM.createElement(script);
script1.setAttribute(type, text/javascript);
script1.setAttribute(src, http://maps.google.com/maps?
file=apiv=2sensor=falsekey=ABQIpOR5tulUc5y1R6lOKFkbpRTwM0brOpm-
All5BF6PoaKBxRWWERTqbaRJ6lpQdSlaltvv3tD-fLXwvQ);
RootPanel.getBodyElement().appendChild(script1);

This code leads to an error when it's loaded (Unloading module) :
its unload my application module.

I am still looking for a way to load dynamically google map.

Regards,

Vincent COROLLEUR

Re: Date Serialization issues

2010-08-09 Thread AaroeiraA

Hi,

You can do something like this:
Write custom Date/Time serializers and put them in the root of your
project. Like this:

Project
| - your.package.com
| - com.google.gwt.user.client.rpc.core.java.sql
| - com.google.gwt.user.client.rpc.core.java.util

The custom serializers NEED to be named:

Date_CustomFieldSerializer.java
Timestamp_CustomFieldSerializer.java

When writing the serializers, import the right types (java.sql.Date,
java.util.Date, java.sql.Timestamp)

Sorry for my english.

 You can't change the timezone. You can't even create a date on the
 client and tell it what timezone it should be in - Javascript does not
 provide a way to do this.

 If you want dates on the client to appear to be the same time of day and
 date as it is on the server, regardless of the client's timezone, and
 you are using GWT serialization, then you have two options:
 (1) Avoid Date objects in your DTOs, and use some encoding of your own
 instead
 (2) Modify GWT itself so that its custom serializers for java.util.Date,
 java.sql.Date and java.sql.Timestamp serialize the
 day/month/year/hour/minute separately instead of storing the time since
 1970.

Re: [UIBinder] - Nested Panels

2010-08-09 Thread Christian Goudreau

It's because Vertical panel can only append Widgets. Your Hello, should be
nested inside a: g:HTML or g:Label

Don't forget that the same html rules are as plain old HTML are effective
inside UiBinder (That's why it's such a nice tool).

So you could achieve the same thing only by knowing if your widgets are
Inline or not.

so:

g:HTMLPanel

g:VerticalPanel

Hello, g:ListBox ui:field='listBox' visibleItemCount='1'/.

/g:VerticalPanel

/g:HTMLPanel

could become:

g:HTMLPanel
Hello, br/
g:ListBox ui:field='listBox' visibleItemCount='1'/.
/g:HTMLPanel

Try to use as much normal HTML and CSS as you can !

Cheers,

Hi all,

I have recently jumped on the GWT bandwagon and have to say I am a big
fan. It makes developing javascript applications fun again.

I have produced many Flex based projects in the past and have come
accustomed to using MXML markup to declare user interface elements. I
can see that GWT's UIBinder functionality is to GWT what MXML is to
Flex so am very keen on getting my head around how it works.

I am currently working my way through the UIBinder tutorial (http://
code.google.com/webtoolkit/doc/latest/
DevGuideUiBinder.html#Hello_Widget_World) and have a query regarding
using Widgets and nested Panels.

I have implemented the 'Hello Widget World' section of the tutorial
and it works perfectly. However if I modify the
'HelloWidgetWorld.ui.xml' to include a nested vertical panel I find
that the app no longer displays any content. Can anyone see why this
may be the case? Details below:

Step To Reproduce

Replace HelloWidgetWorld.ui.xml with the following XML

ui:UiBinder xmlns:ui='urn:ui:com.google.gwt.uibinder'
xmlns:g='urn:import:com.google.gwt.user.client.ui'

g:HTMLPanel
g:VerticalPanel
Hello, g:ListBox ui:field='listBox' visibleItemCount='1'/.
/g:VerticalPanel
/g:HTMLPanel

/ui:UiBinder

Results

After compilation our host page displays a blank screen.

Desired Results

The above code takes the example in the 'Hello Widget World' tutorial
and wraps the components in a nested vertical panel. Ideally both the
HTML Text node and Listbox should now display vertically instead of
horizontally (the default behaviour).

regards
Ben

Exception while dispatching incoming RPC call Object Manager has been closed (repost)

Hey, I've been trying to get my RPC Call to AppEngine to work since
last Wed, with no luck. My issue now seems to be with my query. I'm
willing to post any code needed, but I just want to get this working,
as this has completely halted me on any further progress on my app.
Everything looks like it should be working. Here is my
TestServiceImpl.java :


package com.spierce7.gwt.test.server;

import java.util.ArrayList;
import java.util.Date;
import java.util.List;
import java.util.logging.Logger;

import javax.jdo.JDOHelper;
import javax.jdo.PersistenceManager;
import javax.jdo.PersistenceManagerFactory;
import javax.jdo.Query;

import com.google.gwt.user.server.rpc.RemoteServiceServlet;
import com.spierce7.gwt.test.client.TestService;
import com.spierce7.gwt.test.shared.PersistentShift;

public class TestServiceImpl extends RemoteServiceServlet implements
TestService{
private static final Logger LOG =
Logger.getLogger(TestServiceImpl.class.getName());
private static final PersistenceManagerFactory PMF =
JDOHelper.getPersistenceManagerFactory(transactions-optional);

public void addShift(Date startDate, Date endDate) {
PersistenceManager pm = getPersistenceManager();
try {
pm.makePersistent(new
PersistentShift(startDate, endDate));
} finally {
pm.close();
}
}

public ListPersistentShift getShifts() {
PersistenceManager pm = getPersistenceManager();
ListPersistentShift results = new
ArrayListPersistentShift();

Query query = pm.newQuery(PersistentShift.class);
query.setFilter(search == 1);

try {
results = (ListPersistentShift)
query.execute();
} finally {
pm.close();
}
return results;
}

private PersistenceManager getPersistenceManager() {
return PMF.getPersistenceManager();
}
}

___

My addShift function works fine, and I can add objects to the database
just fine. I just can't retrieve them. I finally changed the objects
in the database to all have an int variable called search, and it's
always set to 1. When I call the getShifts() method though, it gives
me this error:

... (it goes on)

___

I saw some examples where queries are ended with query.closeAll(), and
I tried that also, but I get a different error telling me something
couldn't be serialized from the datanucleus. At this point I just want
it to work. Any help, or any ideas would be great. Let me know if
you'd like some other code posted.

I think GWT/Roo should support at least two basic skin: a light theme
with few/no images/resources (http://gwt-bikeshed.appspot.com/
Scaffold.html isn't a bad start to me!) and maybe an heavier more
appealing one but I think some effort should be done to distinguish
GWT/web applications from desktop app. I would use more/nicer effects
(slide, fade ecc.) to have smoother transitions and/or communicate to
the user that something is happening/has happened (think of mobile
apps also...).

Just my 2 cents

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: onModuleLoad() Before Page Load

I'm not familiar with a lot of the things that you are using, however
GWT has a method that it calls after the widget that the method is
attached to is loaded. It's called onLoad(). Typically, when I've used
it in the past, it's because I was extending a widget, say a Grid, and
then I would override the onLoad() method. I'm not sure how you would
implement it into a completely custom widget though. You might be able
to put the iframe in a HTMLPanel or something, and call the onLoad()
method. Either way, I think this may be what your looking for. Hope
this helps!

On Aug 6, 9:54 pm, Ryan McDonald ryan.mcdona...@gmail.com wrote:
 To my understanding, the compiled GWT file module-name.nocache.js
 blocks page evaluation when it is loading. When it finishes, it
 creates a hidden iframe that begins to load the module-name.cache.js
 file but it does NOT block page evaluation and loads asynchronously.

 In my GWT module I define a native Javascript function using JSNI that
 adds a widget to the page.

 I use a Velocity Template that dynamically generates divs with unique
 ids, then call my Javascript method that I defined using JSNI to
 attach the widget to the specific div.

 The problem is that when my page is loading, and the Velocity Template
 calls my Javascript method, the hidden iframe has not finished loading
 the module-name.cache.js that defines the method.

 Is there a way to make the module-name.cache.js file load
 synchronously so that it will block page evaluation until it finishes
 loading? Or make onModuleLoad() run before the page loads completely?
 Something along these lines?

Re: bug in Animation class

I'm going to be delving into the animation world in the next few
weeks. Thanks very much for this. I'll try to keep this in mind if I
have any issues.

On Aug 6, 11:24 am, Michael michael.vill...@gmail.com wrote:
 Hi,

 I didn't see a place to post bugs, so I am submitting it to the group.

 I've been working with GWT for a one off project on our 
 website,www.studyisland.com. I was attempting to use the Animation class (in
 package com.google.gwt.animation.client) and could not figure out a
 way to get an animation of an Image object to replay when I clicked on
 it. I tried both rerunning the original Animation instance recreating
 the instance and attempting to run it. My code is identical to the
 example in the GWT showcase, with the exception that I create 3 unique
 animations, one for each image on the page.

 The showcase animation can be replayed, but in my case, where 3
 animations existed the animations could not.

 Digging into the Animation class, it is obvious why this is by the
 line of code in the method run(int duration, double startTime):

 // Restart the timer if there is the only animation
     if (animations.size() == 1) {
       animationTimer.schedule(DEFAULT_FRAME_DELAY);
     }

 So, you can't re-run an animation if you create more than one
 animation instance on your page. Thats fine, there may be some
 limitation that I'm unaware of to prevent this. I'll just reset the
 Animation class back to its initial state and start over... but I
 can't because the animations are driven by an array called
 animations that is a private static member of the class, and there
 are no accessible methods to reset it.

 Fortunately the easy solution for me is to just copy all of the code
 in the Animation class into a new class, and add a method
 resetAnimations to take care of this.

 public static void resetAnimations() {
   animations.clear();
   animations = null;

 }

 I just call this before re-running any animations, and everything
 works fine.

 Now, I consider myself pretty good with Java, but I'm not a javascript
 expert so I can't say for sure whether doing this is safe or why the
 original programmers didnt include this functionality initially.
 However, I think it very likely that there will be other GWT users in
 the future who might encounter this issue, hence I think it should be
 addressed.

 If you have any questions about my writeup here, or would like some
 code or something like that, feel free to email me:
 michael.vill...@gmail.com.

 I'm loving GWT by the way. Thanks to everyone who has contributed!
 -Michael

Re: Using piriti 0.4.1

2010-08-09 Thread Harald Pehl

Piriti relies on Totoe. Totoe is an alternative XML parser with
namespace support. So please make sure you have the relevant JAR file
in the classpath / eclipse project. Totoe is available under
http://code.google.com/p/totoe/.

Having your POJO in the shared folder is no problem. Just make sure
the folder is included in your module definition. Having the XML in
the shared folder seems a little bit weired to me. Normally you
receive the XML in response to some request you made. Anyway if you
just want to test Piritis XML mappings, you can load the XML using a
ClientBundle:


public interface FooResources extends ClientBundle
{
FooResources INSTANCE = GWT.create(FooResources.class);

@Source(foo.xml)
public TextResource fooXml();

...
}


Make sure foo.xml is in the same package as FooResources. Then you can
get the XML using
FooResources.INSTANCE.fooXml().getText()

- Harald

Re: Problems extending CalendarView

2010-08-09 Thread ctasada

As long as you update your patched code with the newer version every
time you upgrade you GWT version, it should be no problem.

The main issue is that you cannot extend the DefaultCalendarView
directly and the we need to use this kind of hack.

 Are you sure that the behaviour of the GWT compiler is well-defined

Re: Cell click events for incubator's FixedWidthGrid

Are you only wanting to tell if a cell was clicked, or are you wanting
to use specifics, such as the MouseUpHandler, MouseOverHandler, etc.?

If you are using the Grid and all you want to do is tell which cell
was clicked, Grid has a function called addClickHandler() (only works
with the click handler to tell if it was clicked), and you can use the
getCellForEvent() method to retrieve the actual cell object, and from
there call the methods (I think getRow(), and getIndex()), to get the
row and column that it's in.

If you want to do MouseUp handlers etc, shoot me an e-mail and I can
help you with that. That's a bit more convoluted.

On Aug 7, 7:55 pm, Strannik outofvo...@gmail.com wrote:
 Hello,

 Does anyone know how to figure out which cell was clicked on in the
 FixedWidthGrid from the gwt incubator?

 Using grid.addTableListener(...) seems to be deprecated a while ago
 and does nothing (it probably worked in pre gwt-1.6).

 The GWT API reccomends to use:
 HTMLTable.getCellForEvent(com.google.gwt.event.dom.client.ClickEvent)

 however the incubator FixedWidthGrid extends it's own HTMLTable which
 does not even support adding click handlers.

 It is still possible to use .addRowSelectionHandler(..) though that
 does not appear to tell you which cell on a row was clicked.

 Thank you

Is this possible?
Because our javascript that was compiled is called from other html

Also, I missed the previous entry about the Consulting Services
category... I've added that as well.  Thanks for the support of GWT

As far as using GWT Platform, that is exactly why we need a

Oh, and by the way, the previous link will still work but I've mapped

Re: GWT Popup Menu - Close on losing focus

Are you wanting it to close when you lose focus, or simply when your
mouse exits the panel? In my mind, the popup would lose focus when
you actually click outside of the popup, rather than just moving the
mouse out of it. I'm going to address the question in regards to your
mouse exiting the panel as it would be the more difficult thing to do.

I'm not sure what you are using for a pop-up method, but I would
recommend taking a look at the MouseOutHandler, and the
MouseOverHandler. I would add a MouseOutHandler to the popup, so if
they moved the mouse out, it would call a method where you could close
the popup. Another way to do this is if when the popup comes up, you
could create an invisible panel that is in front of your entire
program, but still is behind your popup popup, and give it a
MouseOverHandler so that whenever it is moused over (meaning whenever
you mouseover any part of your program that is not your popup) it will
call a method, that you can have close the popup. Something I'd
consider beforehand is, what if their mouse is not in the popup when
it's created, then it will close really really fast before they have
time to read it. You would have to make sure they mouse over the popup
prior to it being able to close.

If you wanted to do it the focus way, I'd do the latter method listed
above, but rather than using a mouse over handler for the invisible
panel, I'd use a mouse click handler, or MouseDownHandler.

If you are new to GWT Events, I'd recommend taking a look at the
following links:

knowing module inheritance

Hi folks,

I have a bit of a peculiar need.  I work on a site with a number of
disparate GWT modules:

moduleA
moduleB
moduleC

They all attach to different spans and enhance site functionality.

To load them all when the page loads, I have a loader module
(loaderModule) which inherits from all modules.

That's all well and good when a page is loaded normally.  However, I'm
now looking at having the page loaded via XMLHttpRequest aka
RequestBuilder.  In this case, loaderModule.onModuleLoad() method is
never called automatically.  When I try to call it, nothing happens.

Here's example code:
---

RequestBuilder rb = new RequestBuilder(RequestBuilder.GET,myurl);

rb.setCallback(new RequestCallback() {
@Override
public void onResponseReceived(Request request, Response 
response) {

DOM.getElementById(container).setInnerHTML(response.getText());
new LoaderModule().onModuleLoad();
}

@Override
public void onError(Request request, Throwable exception) {
// TODO Auto-generated method stub
}
});

try {
rb.send();
} catch (RequestException e) {
}
---

Now, if I call moduleA.onModuleLoad() things seem to work fine.  So I
suppose I could just maintain the module list in two places (in the
LoaderModule xml file and in the code).  But I was wondering if
* there was a way to automatically chain the onModuleLoad methods, or,
barring that,
* find out what modules the module I'm currently executing has
inherited from.

I did some searching on the google web toolkit group, but didn't find
anything that seemed applicable.

Any ideas?

Thanks,
Dan

Re: HTML Table

Hi,

The name of that method is a bit misleading.  HTMLTable inherits
setTitle from the UIObject class, and from the javadoc:
http://google-web-toolkit.googlecode.com/svn/javadoc/2.0/com/google/gwt/user/client/ui/UIObject.html#setTitle(java.lang.String)

this method:
Sets the title associated with this object. The title is the 'tool-
tip' displayed to users when they hover over the object.

Are you seeing that?

Thanks,
Dan

Re: Script tag dynamic loading

Hi Vincent,

You might want to look at this project:

http://code.google.com/p/gwt-google-apis/wiki/MapsGettingStarted

This not only has gwt bindings for google maps, but also has a way to
load the API dynamically (using the ajax loader):
http://gwt-google-apis.googlecode.com/svn/javadoc/maps/1.1/com/google/gwt/maps/client/Maps.html#loadMapsApi(java.lang.String,%20java.lang.String,%20boolean,%20java.lang.Runnable)

Re: onModuleLoad() Before Page Load

Hi Ryan,

This doesn't answer your question, but I was wondering why you had the
velocity template initiate attaching your widgets to your spans?

Another possibility is to have velocity write a list of span ids to a
hidden span, and then have your GWT component (in a startup module)
read that span and attach widgets to each span in turn.  That's the
way I do things.

Thanks,
Dan

GWT, web service and reverse ajax/Comet

2010-08-09 Thread noosy

I'm after some advice regarding having a web service inside my GWT
project. The web service is an event consumer and I would like to
update my client side GWT code everytime it consumes a new event. Is
there a reverse ajax/comet approach that I could use here? Is it
possible for my web service to call my GWT server side code on the
event firing, and in turn have the GWT server side code return the
results back to the client side code? I'm trying to avoid a polling
approach. All ideas are welcome, thanks.

I have found StreamHub, GWT-Comet (and more) online but I'm not sure
if I can use these libaries in the manner I am proposing...

Thx for your help mooreds, but i need to run google map without JAR, i
have to load it with a script.

This script is reachable with an URL. Before, i used to do it with a

Now the user of my application can choose his type of map (google map,

to the map API choosed.

Re: onModuleLoad() Before Page Load

2010-08-09 Thread Ryan McDonald

Calling an onLoad() method for the widget would be called after the
widget has loaded though. My problem is that I can't call my method
from the script to tell it to create the widget in the first place. I
need a way to make my HTML page know that it shouldn't do anything
else until my script has finished loading so it can recognize my
method. Also, the hidden iframe that is generated is all done behind
the scenes by GWT, isn't it? So I can't really manipulate that in any
way, I'm assuming.

On Aug 9, 6:28 am, spierce7 spier...@gmail.com wrote:
 I'm not familiar with a lot of the things that you are using, however
 GWT has a method that it calls after the widget that the method is
 attached to is loaded. It's called onLoad(). Typically, when I've used
 it in the past, it's because I was extending a widget, say a Grid, and
 then I would override the onLoad() method. I'm not sure how you would
 implement it into a completely custom widget though. You might be able
 to put the iframe in a HTMLPanel or something, and call the onLoad()
 method. Either way, I think this may be what your looking for. Hope
 this helps!

Re: onModuleLoad() Before Page Load

2010-08-09 Thread Ryan McDonald

My velocity template is in charge of dynamically creating my page.
Basically I have a Velocity macro to create two DateBox widgets so
that a date range may be input by a user. My macro is called whenever
I am generating a page that requires a date range input.

For the list of span ids, that would require all my widgets to be
added in the same span, so be in the same place in the page. My page
needs my widgets to be able to be embedded wherever I choose. The only
way I could think of accomplishing this was creating a GWT JSNI method
that takes a div id string as a parameter so it knows where to attach
my widget.

Re: onModuleLoad() Before Page Load

Hi Ryan,

I guess I wasn't clear about the span solution.

What I mean is for the velocity template to build a span like this:
span id=component-config
style=display:nonecomp-111,comp-112,comp-113/span

And then in the gwt component startup method, read the component-
config span, split on commas, and attach components to each id found
there (if it exists).

Does that make a bit more sense?

 For the list of span ids, that would require all my widgets to be
 added in the same span, so be in the same place in the page. My page
 needs my widgets to be able to be embedded wherever I choose. The only
 way I could think of accomplishing this was creating a GWT JSNI method
 that takes a div id string as a parameter so it knows where to attach
 my widget.

  Hi Ryan,

  This doesn't answer your question, but I was wondering why you had the

  Another possibility is to have velocity write a list of span ids to a
  hidden span, and then have your GWT component (in a startup module)
  read that span and attach widgets to each span in turn.  That's the
  way I do things.

Re: Script tag dynamic loading

I don't understand?

The gwt maps project is GWT.  Do you want to load the map via GWT, or
before GWT loads?  If after GWT loads, you could definitely load or
not load based on some user input.

Re: onModuleLoad() Before Page Load

2010-08-09 Thread Ryan McDonald

Ah, that makes more sense now, thanks. While that would work, I am
trying to avoid having to hard-code a list of id's to attach my widget
to. I would like my widget to be able to be reusable and not limited
in the way it's used. My module contains a modified DateBox widget,
and my Velocity Template creates two of them to create a date range
input field. If I hard-code the list of span id's to attach my widget
to, I would have to attach both DateBox widgets inside the Java code
and eliminate the possibility of using only one DateBox widget in a
field for just a plain date picker. If I do it in the Velocity
Template, that can deal with how I lay my widget out which is the
purpose of Velocity.

GWT 2.1 Documention

Does anyone know when there will be some documentation available for
GWT 2.1 even if its preliminary?  We are beginning a revamp of a
project and would like to go ahead and start out with 2.1 because the
new Data presentation widgets would be very very helpful to us.

Adding a GWT page to a frame

2010-08-09 Thread gwtnewbie

Hi,

I'm really new to GWT (and front-end in general) and am trying to
integrate a GWT page into an existing application done in JSP  Struts
1.  I have tried searching around but have not been able to find much
info about what I want to do.  Basically, I want to load my GWT
application/page into a frame instead of filling up the whole browser
window.  The current application has a menu tree frame on the left
hand side (menu.jsp) that loads contents into the frame on the right.
I tried creating an action that forwards to my GWT entrypoint html
using the following:

div class=leafhtml:link action=/myAction.actionLink to my GWT/
html:link/div

Clicking on the link shows a blank page, but when I look at the page
source, I do see the entrypoint html code there.  Perhaps this is not
the right direction.

It is not possible to completely rewrite the existing application in
GWT at this point, so I need to find a way to do this.  Any help is
greatly appreciated!

Thanks!
PN

Re: Using piriti 0.4.1

2010-08-09 Thread Deepak Singh

Hi Harald,

Thanks for your guidance.

I did all these things as stated by you. I included the jar file of totoe.
Reads xml through clientBundle. But while compiling i get the following
error

Loading inherited module 'name.pehl.piriti.Piriti'
   Loading inherited module 'com.google.gwt.inject.Inject'
  [ERROR] Unable to find 'com/google/gwt/inject/Inject.gwt.xml' on your
classpath; could be a typo, or maybe you forgot to include a classpath entry
for source?
   [ERROR] Line 8: Unexpected exception while processing element 'inherits'

So the compilation failed.

I have injected these two in .gwt.xml
inherits name=name.pehl.totoe.Totoe /
inherits name=name.pehl.piriti.Piriti /

Do i need to include anything else in the project ?

Thanks
Deepak

 Piriti relies on Totoe. Totoe is an alternative XML parser with
 namespace support. So please make sure you have the relevant JAR file
 in the classpath / eclipse project. Totoe is available under
 http://code.google.com/p/totoe/.

 Having your POJO in the shared folder is no problem. Just make sure
 the folder is included in your module definition. Having the XML in
 the shared folder seems a little bit weired to me. Normally you
 receive the XML in response to some request you made. Anyway if you
 just want to test Piritis XML mappings, you can load the XML using a
 ClientBundle:

 
 public interface FooResources extends ClientBundle
 {
FooResources INSTANCE = GWT.create(FooResources.class);

@Source(foo.xml)
public TextResource fooXml();

...
 }
 

 Make sure foo.xml is in the same package as FooResources. Then you can
 get the XML using
 FooResources.INSTANCE.fooXml().getText()

   Hi All,
 
   I am using piriti 0.4.1 for mapping XML to POJO's with gwt 2.1 m2.
   For learning purpose, i added on sample xml file to shared folder and
   created the java classes in shared folder only. But these java classes
 show
   the following error
*The type name.pehl.totoe.client.Element cannot be resolved. It is
   indirectly referenced from required .class *
   * files*
   *
   *
   I am using eclipse 3.5 and have added jar files in build path through
   eclipse.
   I don't actually know what mistake in setting up the project i am
 doing.
   I am not using maven.
 
   Pls let me know how to use piriti and is there any way to do mapping of
 xml
   to pojo.
   Is Piriti a better solution for fast result ?
 
   Thanks

Re: Making GWT look good...

2010-08-09 Thread Chi H

On the topic of the widget set.
 * One thing we do internally is use deferred binding on some of our
custom widgets to deal with different browsers having different levels
of functionality.  For example, in our custom styled button widget, we
use CSS3 properties (e.g.: border-radius) to render buttons on CSS3
browsers, and the CSS2 sliding doors technique (which use images for
rounded corners) to render identical looking buttons on less capable
browsers.   One advantage of using border-radius on the browsers which
support it is that you avoid aliasing when zooming in on the page.
This has been very successful for us, it should be something to
consider for new widgets where appropriate.
 * Performance is important.  Sluggish sites are not fun to use.  I
love how the GWT team is already so focused on performance, please do
not lose sight of it while you are in the process of making it look
good.



On the topic of the scaffolding app:
 * Pagination is the standard solution to the 'large number of
entities' problem.  However, there is a usability cost to pagination.
It would be really nice to get rid of the pagination and just use a
scrollbar.   If you used the approach of SlickGrid (http://
wiki.github.com/mleibman/SlickGrid/), where you only rendered what was
visible on the screen, you can render large numbers entities without
the need for pagination.
 * Alternatively, you can just provide developers with the choice
between using a scrollbar and with using pagination.  This is what we
have done internally - in practice, 80% of our crud pages are 'low
cardinality' (e.g.: 300 entities) - and we show low cardinality pages
by displaying all elements inside a standard ScrollPanel.   For extra
usability points, if you have a table, the headers should stay on
screen as you scroll the data down.
 * Assuming we stick with pagination, why are there only 8 entities on
a page?  That wastes a lot of screen real estate, there is a big blank
below.  Ideally, the list would fill all available space on the page.
That would be more difficult, but either way, but 8 is far too low if
it is going to be set to a static number.
 * When you click 'create employee' the 4 input fields for employee
creation appear below the search list.   That works well enough if
there are only 4 input fields, and 8 items on a page, as is in the
demo.  However, we had CRUD screens with 50 input fields.  We also
want to put a lot more than 8 items on a page.   So, the input fields
would need to be on their own page, replacing or overlaying the 8
entities in the list.   This is one of those things where there is no
one-size-fits all solution, but our experience is that a large number
of input fields is more common than a small number.


One last 'wishlist' point:
 * We've actually developed our own GWT-based CRUD infrastructure
recently - versioning/duditing is one of the biggest reasons we ended
up creating our own infrastructure instead of reusing an existing
one.  When an entity is created, it is created as 'v1'.   When it is
edited, we just create 'v2', mark it as current, and leave 'v1'
alone.  When the entity is deleted, we just mark it as deleted.
Because of this, in addition to just CRUD screens, we also have an
audit trail screen that lets users see all previous versions of an
entity, when each change was made, and who made each change.  And
users can then select an older version of the entity and 'revert' back
to that version.
 * Undo/redo fall nicely out of versioning as well - undoing an edit
is just reverting back to the prior version
 * We haven't yet implemented it ourselves, but 'future dated
changes' (changes that only take effect on a date in the future) and
'approved changes' (changes that must be approved by another user
before they take effect) fall nicely into that pattern as well
 * I know we aren't the only company to have to deal with this, if
GWT's built-in infrastructure had this, and did it really well, I
believe it would be a huge win in the enterprise market.
 * Even if GWT's built in infrastructure didn't have this built in,
this type of thing shows how important it is for the framework to be
easily extendable, so that developers can add this to the framework if
needed.
