This is where I am rather confused. As when i move it to
a package which isn't named in the .gwt.xml file I receive
an error of cannot be resolved to a type. Which is fair enough,
as I assumed everything in the .gwt.xml was putting the classes
in 'view' of everything in the application? Or perhaps I'm very
muddled up!

Sorry for the continued annoyance! I very much apologise.

 Hi day_trader

 As far as i can think is that you are trying to pass an object with
 the data of the class..

 now to make your class go to the server side all you need to do is to
 move it to a package that is in the package that is *not* mentioned in
 your your_gwt_xml.gwt.xml file as the classes in these
 packages,which are mentioned in the gwt.xml file, get ajaxified and
 sent on to the client.

 Hope this helps.

Re: Problem with Eclipse, Google plugin and WTP

2010-07-07 Thread SimonM

Hey Rajeev,

The WAR folder is set to WebContent.
The box was checked, so I unchecked it, but it didn't change the fact
the libs weren't copied/deployed correctly.


Thanks for helping,

 Hey Simon,

 If you navigate to the smart-ui project properties - Google - Web

  Hello,

  I have troubles with WTP and Google plugin for Eclipse.

  I have one Dynamic Web Application Project, and I use GWT in this
  project. It's smart-ui.

  I have a Java Project which contains all business logic, it's smart-
  business : smart-ui depends on smart-business. All is correctly
  exported in Java EE Module Dependencies.

  Now I use WTP to deploy on a local JBoss, and all is working except
  one thing : the libraries of project-ui are not deployed in WEB-INF/
  lib. The project itself is compiled, packaged and deployed in this
  directory.

  I have found after investigating several hours I can deploy correctly
  if I set in the Java Build Path (in Eclipse)  the Default output
  folder to build/classes (and not WebContent/WEB-INF/classes). All libs
  are present in WEB-INF/lib. I can even set the folder to build/
  classes for example, it works.

  Meanwhile I have a new error in my project :
  The output directory for the project should be set to /smart-ui/
  WebContent/WEB-INF/classes      smart-ui-gxt            Unknown Google Web
  App
  Problem

  If I set the Default output folder back to WebConten/WEB-INF/classes,
  I don't have the error anymore but the libs aren't exported to WEB-INF/
  lib.

  I think there are some incompatibilities between WTP and Google plugin
  there.

  Am I missing something ? Is this a know issue and does a workaround
  exist ?

  Thanks for helping.

Re: onSuccess() return value other than void?

You do not have to move something out of 'client' packages to have it
on your server. This is definitely wrong!

You do have to move classes you want to have on the client or both
client and server into the client packages (or declare those packages
in your *.gwt.xml files).

Since you want your class to be passed from the client to the server
this class definitely needs to be in your 'client' package. I don't
know why you get an error on compiling, maybe you can give more
informations on this one. GWT compiles all Java files (also those in
'client') to .class files in your war/WEB-INF/src/ folder so all
classes will be accessible on the server.

Re: onSuccess() return value other than void?

The inherits tag is for inheriting GWT modules not for inheriting Java
files or similar (afaik).

You add packages to the GWT translatable sources via source tag:

source path='client'  /

This should be enough assuming your GWT module is in 'com.myApp'.

MVP : model and duplicate

2010-07-07 Thread SimonM

Hi,

I have some troubles with MVP : as I have understood, the model should
just be business objects which are present in a shared package, so
client and server can access them from a GWT point of view.

In a three layered application how do you not duplicate these business
objects, while you have beans used in the business layer ? From what I
understand they are the same objects but in two different layers, so
we need two different classes.

Where is my mistake ?

  This should be enough assuming your GWT module is in 'com.myApp'.

 You do have to move classes you want to have on the client or both
 client and server into the client packages (or declare those packages
 in your *.gwt.xml files).

 Since you want your class to be passed from the client to the server
 this class definitely needs to be in your 'client' package. I don't
 know why you get an error on compiling, maybe you can give more
 informations on this one. GWT compiles all Java files (also those in
 'client') to .class files in your war/WEB-INF/src/ folder so all
 classes will be accessible on the server.

   As far as i can think is that you are trying to pass an object

   now to make your class go to the server side all you need to do 
   is to
   move it to a package that is in the package that is *not*

   your your_gwt_xml.gwt.xml file as the classes in these

around my

Hiding module name from curious users

2010-07-07 Thread Aekold

Good day all!

Tell me please what is the best way to hide module name and all
possible branding stuff from users?

The problem is, I am working on application that will be reselled, and
reseller does not want end users to see the name of developer company
at all. At the same time I do not want to cripple java packages and
GWT module name.

The first solution that comes in mind - to separate all my stuff in
library, create project with entry point and simple name that will
inherit from library. But what to do with RPCs then if they have to be
declared in web.xml? Maybe use Guice to use single Guice servlet and
annotation-based mappings for servlets, but not sure if it will
work...

The other solution that comes in mind - to use some fancy obfuscator
that will be smart enough to change modulename.gwt.xml and main.html,
but I find it hard to believe obfuscators can be that smart...

Any way, any suggestions and ideas are appreciated.

Re: I18N and dynamic texts

2010-07-07 Thread arjanDOTTYbroerATgmailDOTTYcom

Thanks for the answer Andre.

I'll try to describe the way i have chosen to solve this.

I have created a TextBundle that is pretty much a simple MapString,
String. I have also created a TextPresenter interface that defines
two methods.

SetString getTextKey()
void setTextBundle(TextBundle texts)

There is also a clientside TextManager that takes a TextPresenter and
does a async call to the server to get the bundle for the keys. When
it gets the bundle the TextManager will call the setTextBundle on the
TextPresenter and leaves it to the TextPresenter to update the view
with new texts.

  Arjan

 Well,

 You can create a class that wraps a JavaScriptObject which contains a
 Dictionary with your keys and values.

 And before starting your application you can make a HTTP Request to
 fetch the JSON data (or part of it).

 Than in the server-side your write some code that send the values from
 the database in the JSON format.

 Of course you should not download all the keys from the DB at the same
 time, but you can download part of it when you need.

 Since you will use the MVP, you can write custom events when the
 download of the JSON strings success or fail.

Re: Problem with code which works in compiled mode and fails in hosted mode

Hi Alan,

I think I misled you with my answer. It turns out that the GWT-G3D had
a very similar problem, but not quite the same.

I started using the GWT-GL wrapper, and now I'm having the same
problem as you are!

For some reason, the method
glContext.getUniformLocation(shaderProgram, perspectiveMatrix);

expects an fails because, as you pointed it out, the OOPHM object

RequestFactory Considered Mostly Harmless

2010-07-07 Thread Jeff

I've spent a bit of time over last five days reviewing the
RequestFactory and I have to say it rocks.  I started with the
STS-2.3.3-M1 roo generated projects and just kept digging into what
was driving them.  I found a few waves and have been reading through
the code reviews and commits, but perhaps you could answer a few
questions to help my research?

How much is different between what's in the bikeshed project in
gwt-2.1.0-M1 and the M2 classes (small, medium, large)?  I do see a
few interfaces have been removed (ServerOperation and ServerType) - I
just haven't had time to do a deep comparison.  I would suppose it is
safe to just use M2 for playing with this new API?

The best overview I've found was on this wave:
https://wave.google.com/wave/?pli=1#restored:wave:googlewave.com!w%2BWU4iAICkI

Of course I'm eager to see this all come together.

hello all:

   i have a button and a label on a panel, the button has been
registered a listener:

  Button searchButton = new Button( Search );
searchButton.addClickHandler( new ClickHandler()
{
@Override
public void onClick( ClickEvent event )
{
infoLabel.setText(Beginning);
//do a search operation here which will take more than
5 seconds...
infoLabel.setText(Completed...);
}
} );

that's all, but i never see the Beginning“ on the label, but only
see the completed..., seem the label will not refresh it's text
until onClick is  finished? how can i achieved the function that
display beginning... first and Completed... when the operation
completed?

Who does the bikeshed expense report get populated?

2010-07-07 Thread nalf

I've checked out bikeshed from branch and followed the instructions in
eclipse.README and everything appears to be working. When I go to Run
As -- Web Application -- Expenses.html.it loads fine but
with no data pre-populated..my question is how do I populate this
sample application?

How does Run As -- Web Application --loadExpensesDB.html work?

When run this app, a screen with 5 buttons appears...the last button
is to generate data, but when I click it, I get the following error

Data generation failed
0 Employees
0 Reports
0 Expenses

Bottom line, can anyone point me in the right direction on how to
populate the bikeshed expense report?

If bikeshed is incomplete, is there a hack I can use to populate the
data?

thanks in advance

Write GWT books - Packt Publishing.

2010-07-07 Thread Kshipra Singh

Hi All,

I represent Packt Publishing, the publishers of computer related
books.

We are planning to extend our range of Open Source books based on Java
technology (including GWT) and are currently inviting authors
interested in writing them. This doesn't require any past writing
experience. All that we expect from our authors is a good subject
knowlegde, a passion to share it with others and an ability to
communicate clearly in English.

So, if you love GWT and fancy writing a book, here's an opportunity
for you! Send us your book ideas at aut...@packtpub.com and our
editorial team will be happy to evaluate them. Even if you don't have
a book idea and are simply interested in writing a book, we are still
keen to hear from you.

Packt runs an Open Source royalty scheme so by writing for Packt you
will be giving back to the Open Source Community.

More details about this opportunity are available at:

Re: the button and its infoLabel problem...

Hey Shelley,

a bit of further information is missing but may it be that you issue
an RPC between infoLabel.setText(Beginning); and
infoLabel.setText(Completed);?

If so you simply forgot the async nature of GWT RPC. Your code in
onClick(...) will not sort of stop or wait until the RPC finishes and
continue afterwards. That's why infoLabel.setText(Completed);
will be immediately executed after infoLabel.setText(Beginning);
and you're simply way to slow to see it.

What you could do instead is call infoLabel.setText(Completed);
in your onSuccess(...) in case I'm right with RPC or in the callback
of whatever request you do for your search operation.

Re: MVP : model and duplicate

2010-07-07 Thread Gal Dolber

I think you should avoid duplicate the model objects. Find the way to share
them between all you application or cut off one layer :P

2010/7/7 SimonM simon.manqu...@gmail.com

Hi,

I have some troubles with MVP : as I have understood, the model should
just be business objects which are present in a shared package, so
client and server can access them from a GWT point of view.

In a three layered application how do you not duplicate these business
objects, while you have beans used in the business layer ? From what I
understand they are the same objects but in two different layers, so
we need two different classes.

Where is my mistake ?

Re: Google Plugin for Eclipse 1.4 M2

2010-07-07 Thread Jason Parekh

Hi Jaroslav,

I'm pretty sure it's required for some minor changes needed to get Speed
Tracer to open automatically when launched from GPE. Have you looked into
(or opened a bug about) the profile issues you're having with the dev
channel?

Yes, the clean installation is recommended for milestones only -- mainly
because the code may have a few issues due to its milestone status, so we
wouldn't want your existing stable Eclipse environment to become unusable.
If this doesn't concern you, feel free to install it over your existing GPE

Sounds great. :)

Will (is?) it be possible to use Speed Tracer with stable channel Chrome?
Last time I checked (week ago) development channel Chrome was required;
unfortunately it does not seem to support profiles. (Ctrl+M did not work
with --enable-udd-profiles.)

Also does the clean-Eclipse-installation recommendation apply to the
milestone only?
It is kinda weird to d/l and re-install Eclipse because of plugin update.
:(

There's also a new Google Plugin for Eclipse 1.4 M2 to go along with it.
Check out the new Speed
Tracerhttp://code.google.com/webtoolkit/speedtracer/integration -- a
simple toolbar button will launch Chrome and Speed Tracer
to help you identify and fix performance problems in your web apps. Once
you find an issue, you can click on a link in Speed Tracer to jump directly
to that line of code in Eclipse. There are also many bug fixes, and smaller
features like the ability to double-click URLs in the Development Mode view
or the ability to halt an in-progress Deploy to App Engine or GWT compile.

We recommend you install this on a clean Eclipse installation. Here are
the update sites:

- Eclipse Helios (3.6):
http://google-web-toolkit.googlecode.com/svn/2.1.0.M2/eclipse/plugin/3.6

DockLayoutPanel and MVP

2010-07-07 Thread xworker

Hi

I want to create a simple app with a DockLayoutPanel with a tree for
navigation west and a content panel center which switches when
selection a node in the tree. I'm using the MVP pattern with
Presenters,Views and ui bindings. All my components work by them selfs
but when I try to load the Dock nothing besides the top is shown.
(north)

this is my ui.xml:

ui:style
.header {
background-color: #00;
}

/ui:style


g:DockLayoutPanel unit='EM'
g:north size='15'
g:Label styleName={style.header}Header/g:Label
/g:north


g:center
g:SplitLayoutPanel
g:west size='15'
contacts:MyTree ui:field=treeView /
/g:west

g:center
contacts:ContactsView 
ui:field='contactsView' /
/g:center
/g:SplitLayoutPanel
/g:center
/g:DockLayoutPanel

What could be wrong?

Re: MVP : model and duplicate

2010-07-07 Thread Stefan Bachert

Hi Simon,

One question is what do you mean with duplicate?

In a client-server environment there is an absolute need to duplicate
the value of an object.
Because you need it on server and client side. The process is called
serialization.
However, you can use the same class on both sides.

 When you client just need a smaller set of attributes than your
domain object offers, you need different classes.
The latter happens when multiple applications are working on the same
domain objects.

There are a lot of object/classes which are some how similar but used
in different technical context( e.g with/without lazy loading from
database)
- objects representing database entities (ENTITES)
- objects representing domain objects/model objects (DomainObject,
Business Objects)
- objects representing a snapshot of domain objects
(DataTransferObjects, ValueObject)

the problem has nothing to do with GWT at all, since all the

Your description indicates that your server side code is leaking

RPC method will be called multiple times instead of one time in development mode????

2010-07-07 Thread crojay78

Hi,

I am observing a strange behaviour in the development mode of my
application. I have a RPC call which will store my data in the
background. But this method will be called 5 times on my server??? I
dont get it why this happens, I checked if I make this call anywhere
else in my code, it should be processed only one time.

Does anyone know why this happens and how I can fix it?

Here is the RPC call, which I am doing in the Appcontroller

eventBus.addHandler(StoreConfigurationEvent.TYPE, new
StoreConfigurationEventHandler() {

public void 
onStoreConfiguration(StoreConfigurationEvent event) {

InstanceMailAgentConfig config =
ConfigDataManager.getInstance().getImaConfig();

rpcService.storeConfigForForm(config, new 
AsyncCallbackBoolean()
{

public void onFailure(Throwable caught) 
{
GWT.log(storing of config 
failed, reason was  +
caught.getMessage());

}

public void onSuccess(Boolean result) {
if (result){
GWT.log(config for 
form  +
ConfigDataManager.getInstance().getImaConfig().getFormid() +
successully stored to database);
eventBus.fireEvent(new 
StatusChangedEvent(true));
}
else{
GWT.log(config form  +
ConfigDataManager.getInstance().getImaConfig().getFormid() +  not
stored to database, check logs... something went wrong);
eventBus.fireEvent(new

}

}
});

}
});

 How much is different between what's in the bikeshed project in

The major change is r8309

 I would suppose it is
 safe to just use M2 for playing with this new API?

 The best overview I've found was on this wave:
 https://wave.google.com/wave/?pli=1#restored:wave:googlewave.com!w%2B...

There are still some show-blockers (for us) in M2, mainly the fact
that each server-side object must have a static findXxx() and instance
persist() and remove() methods.

 Of course I'm eager to see this all come together.

So am I!

Shared CSS

2010-07-07 Thread Hethcox

Hello,
I have a GUI library that is used by several GWT apps. I would like
the widgets in the library to use a standard sets of CSS classes from
the library so that they don't have to be copied and maintained in the
apps that  use the library. The library is deployed as a jar
currently, but that can change.

I've read a lot of posts on this topic, but none of them seems to do
the trick. My target platform is JBoss and the closest solution I've
found so far is to put the library CSS file in ROOT.war/css at deploy-
time. Is there a build-time trick to get the GWT apps to deploy the
CSS file when it cross-compiles the library widgets?

Cheers,
John

Manual RPC using RPC.invokeAndEncodeResponse()

2010-07-07 Thread Bálint Kriván

Hiho!

I'm using Atmosphere and I would like to do streaming with GWT-RPC,
currently I'm having a working example, something like this:

My remoteService:
public interface EventService extends RemoteService {
MyEvent getEvent();
}

So on the server side, I'm doing this:
Method method = this.getClass().getMethod(getEvent, null);
String encoded = RPC.invokeAndEncodeResponse(this, method, null);

Now I can broadcast this encoded string as payload and on the client side,
using this I can get the broadcasted object:
(MyEvent) ssf.createStreamReader(message).readObject();
where message is the payload which was broadcasted and ssf is defined like
this: protected static final SerializationStreamFactory ssf =
GWT.create(EventService.class);

This is great, it works like a charm. Then I've discovered this stuff:
com.google.gwt.user.RemoteServiceObfuscateTypeNames. Which would be great
for production. So I've tested it, and of course it breaks my working stuff,
I've modified like this, but still not working:
Method method = this.getClass().getMethod(getEvent, null);
Stringencoded = RPC.invokeAndEncodeResponse(this, method, null,
getSerializationPolicy(
 http://127.0.0.1:/kfc/;, DD98F5EAEFEC65CD76A0D7BC1E3C8E8D));
where getSerializationPolicy() looks like this:

public SerializationPolicy getSerializationPolicy(String moduleBaseURL,
String strongName) {
String modulePath = null;
if (moduleBaseURL != null) {
try {
modulePath = new URL(moduleBaseURL).getPath();
} catch (MalformedURLException ex) {
System.err.println(Malformed moduleBaseURL:  +
moduleBaseURL);
}
}

SerializationPolicy serializationPolicy = null;

String contextPath = servletRequest.getContextPath();
String contextRelativePath =
modulePath.substring(contextPath.length());
String serializationPolicyFilePath = SerializationPolicyLoader
.getSerializationPolicyFileName(contextRelativePath +
strongName);

InputStream is =
context.getResourceAsStream(serializationPolicyFilePath);
if (is != null) {
try {
serializationPolicy =
SerializationPolicyLoader.loadFromStream(is, null);
} catch (ParseException e) {
e.printStackTrace(System.err);
} catch (IOException e) {
e.printStackTrace(System.err);
}
}

return serializationPolicy;
}
It's merely copied from RemoteServiceServlet IIRC. I have 2 problems: what
can I do to not hardcode strongName for gwt.rpc file and the moduleBaseURL?
And finally, why isn't it working? It still makes payload as I would do
without inheriting com.google.gwt.user.RemoteServiceObfuscateTypeNames module,
which is bad, because the client can't deserialize it and throwing
SerializationException.

If you could help me to solve my problem, I would be grateful, thanks!

FlexTables - store invisible database key in row?

2010-07-07 Thread Magnus

Hi,

I would like to use a FlexTable as a list of users and I need to
attach a user id to each row somehow, in order to identify the user
when a row is selected.

I tried to use a column of width 0px, but this column is visible...

How would you do that?

Thanks
Magnus

Re: Error using my own widgets with UIBinder

2010-07-07 Thread Blessed Geek

There is a design deficiency in UiBinder which I am desperately hoping
GWT architects are putting top priorities at rectifying it - you
cannot, for most and practical cases, use your custom-extended
UiBinderable classes with Uibinder, unless you are willing to kludgify
your use of uibinder.

These are the apparent rules that you need to stick to when making a
class uibinderable:
* A class to be used as a parent node of GWT Widgets must implement
HasWidget,
* and any class that is its candidate child node must be an extension
of GWT Widget class.
* A class to be used as parent node of HTML contents must implement
HasHTML.
* A class to be used as a node for encapsulating text content must
implement HasText?.

These are the problems/issues:
* The GWT compiler ignores HasHTML or HasText when HasWidget is
implemented.
* Therefore, a custom UiBinder node cannot have a mix of Widget nodes
with HTML and Text node.
* Most uibinder classes that came off-the-shelf with GWT engage in
insider-trading - they are allowed to skirt around the above rules by
having their own respective parsers.
* That is why insider-traded uibinderable classes can have nodes like
north, south, top, bottom, ..., etc.
* When you extend an insider-traded class, for the most part, the GWT
compiler would consequently create a temporary java source file that
at some point performs the equivalent of.
ExtendedClass uiname = new instance of OriginalClass.
Now, in Java, you can assign variable of an original class to an
instance of its extended class but not vice versa. I do not know if
this is hard-coded in the GWT compiler or in every individual parser.
* For hierarchically related classes like TabBar - Tab or MenuBar -
Menu, the GWT compiler/uibinder parser attempts to look for the child
class from under the same package, disregarding what you declare as
the package namespace in your extension class.

These are the entry-barriers towards investing efforts to customise
your use of uibinder:
* At current state of affairs, we cannot attain the same level of
karma as the insider-traded uibinderable classes because GWT compiler
does not provide a means for us to insert our own parsers.
* More accurately, we can insert our own parsers if we are willing to
make some minor modification to the GWT compiler source and rebuild
GWT from source.

There are the kludgifications that could mitigate the current state of
affairs with uibinder. For example, you could hijack the namespace
com.google.gwt.user.client.ui when extending classes that have a
hierarchical relationship, which I demonstrate here:
http://h2g2java.blessedgeek.com/2010/04/patch-extending-insider-traded-uibinder.html.
Or hijack the original classes altogether by replacing and appending
the original source with code of your personally preferred behaviour.

However, the elegant solution is of course to rectify the behaviour
and characteristics of the GWT compiler rather than having us resort
to such neck-breaking kludgifications.

I believe the gwt-mosaic uses its own patch for the gwt compiler to
allow it to insert is own parsers: project http://code.google.com/p/gwt-mosaic/

Perhaps, and if I could beg y'all for a pardon, we should come
together and agree on a way to patch gwt compiler and set up a google
code project for this patching, while we let the gwt architects to
peacefully mull over what the best way should be to treat these
uibinder deficiencies. Which means, we would need to mirror every GWT
release with this patched GWT.

Re: FlexTables - store invisible database key in row?

2010-07-07 Thread Subhrajyoti Moitra

one way might be to use a ListUser userList private variable in the
widget..
the state of the flextable is same as the state of the userList.

when a row is selected.. depending on what event selects the row (mouse
over, mouseclick..).. update a private User currentUser object.

public class MyUserListView extends Composite {
private FlexTable userListTable;
private ArrayListUser userList=new ArrayListUser();
private User currentSelection;
public MyUserListView() {
userListTable=new FlexTable();
userListTable.setBorderWidth(1);
DOM.setStyleAttribute(userListTable.getElement(), cursor,
pointer);

initWidget(userListTable);
userListTable.addClickHandler(new ClickHandler() {

@Override
public void onClick(ClickEvent event) {
Cell cellClicked= userListTable.getCellForEvent(event);
int rowIndex=cellClicked.getRowIndex();
currentSelection=userList.get(rowIndex);
Window.alert(U have choosen User:
+currentSelection.getFirstname());

}
});
}
/**
 * This will mostly be defined in the Presenter view interface.
 * @param u
 */
public void addUserToUserTable(User u){
userList.add(u);
int row=userListTable.getRowCount();
userListTable.setWidget(row, 0, new HTML(u.getFirstname()));
userListTable.setWidget(row, 1, new HTML(u.getLastname()));

}

public User getCurrentSelection() {
return currentSelection;
}



}

in the client class that uses this widget,

MyUserListView mul=new MyUserListView();
mul.addUserToUserTable(new User(Firstname1,lastname1));
mul.addUserToUserTable(new User(Firstname2,lastname2));
mul.addUserToUserTable(new User(Firstname3,lastname3));
mul.addUserToUserTable(new User(Firstname4,lastname4));
mul.addUserToUserTable(new User(Firstname5,lastname5));
outerPanel.add(mul);

There are a lot of limitations to this as, u can point out. but it sorts the
basic issue of maintaining the current state of selected row. there should
be better ways to handle this. Experts please comment.

Thanks,
Subhro.

With the latest versions of GWT you don't have to use any other

GWT now comes with something known as Javascript Overlays that you can
utilise to convert JSON into Objects.

See here:

problems aligning widgets in DockLayoutPanel

2010-07-07 Thread Thad

I've just completed substituting a DockLayoutPanel for a DockPanel in
one of my application's widgets.  This has *not* been easy, primarily
because of what appear to me to be bugs with the alignment of widgets
along the north, south, east, and west of the DockLayoutPanel.  I have
managed work-arounds.  Let me explain:

In my old code, I could say

DockPanel panel = new DockPanel();
panel.setHorizontalAlignment(HasHorizontalAlignment.ALIGN_CENTER);
panel.setVerticalAlignment(HasVerticalAlignment.ALIGN_MIDDLE);

Now when I use panel.add(upArrowBtn, DockPanel.NORTH) etc. each
button centers.

In the new code, alignment in the cardinal subpanels works differently
between IE7 and Mozilla 3.6.6.  I have found what I believe are bugs
with each.

First, with the north and south directions, this technique works to
center my buttons (which are 16x16 PushButtons):

DockLayoutPanel panel = new DockLayoutPanel(Style.Unit.PX);
panel.addNorth(upArrowBtn, 18.0);
panel.getWidgetContainerElement(upArrowBtn).setAttribute(width,
100%);
panel.getWidgetContainerElement(upArrowBtn).setAttribute(align,
center);

However, this does NOT work with east and west. When I use

panel.addWest(leftArrowBtn, 18.0);
panel.getWidgetContainerElement(leftArrowBtn).setAttribute(height,
100%);
panel.getWidgetContainerElement(leftArrowBtn).setAttribute(verticalAlign,
middle);

the leftArrowBtn is not centered vertically. Looking with Firebug, I
see why:  In the north and south panels, only style height is other
than zero (style=position: absolute; overflow: hidden; left: 0px;
right: 0px; bottom: 0px; height: 18px;), whereas in the east and west
panels, only right is zero (position: absolute; overflow: hidden;
top: 18px; right: 0px; bottom: 18px; width: 18px;).  Moreover,
verticalAlign has NOT been translated from camelcase to hyphenated
vertical-align.  (This also seems the case with IE7 and Safari 4,
but in IE my Developer Toolbar is broke--it won't display.)

I've managed to get east and west to align using a LayoutPanel:

LayoutPanel lpW = new LayoutPanel();
lpW.add(leftArrowBtn);
lpW.setWidgetTopHeight(leftArrowBtn, 50.0, Style.Unit.PCT, 100.0,
Style.Unit.PCT);
panel.addWest(lpW, 18.0);

LayoutPanels also work for north and south in Firefox and Safari, but
are broke in IE7.  When I use

LayoutPanel lpN = new LayoutPanel();
lpN.add(upArrowBtn);
lpN.setWidgetLeftWidth(upArrowBtn, 50.0, Style.Unit.PCT, 100.0,
Style.Unit.PCT);
panel.addNorth(lpN, 18.0);

I get centered buttons in Firefox and Safari, but in IE7, the buttons
are shoved to the far right, as if the left edge of 50% is being
ignored.

So, getWidgetContainerElement for north and south, LayoutPanels for
east and west.  This does not seem right.

GWT 2.0.4 caused Class Not Found, TransformerFactoryImpl

2010-07-07 Thread emurmur

I have an Java App Engine project using SDK 1.3.5 and the latest
Restlet GAE 2.0rc4 to implement some restful services.  Everything
worked well (this has been in production for 6 months) until I added
GWT 2.0.4 to the project.  As soon as I check use GWT on in the
control panel in Eclipse (without even adding a module) my services
start to fail in the development server with the following class not
found exception:

Couldn't write the XML representation: Provider
org.apache.xalan.processor.TransformerFactoryImpl not found

This exception happens on the way out of my Restlet, after a GET of a
lists of entities, as it tries to turn my DomRepresentation into the
response payload.  I've found that if I remove the gwt-dev.jar, the
exception does not happen.  Of course, I can't use the development
server if I do that.   Again, this all works fine without GWT.

Here is the relevant parts of the trace:

Re: cookies and expiry

2010-07-07 Thread dominic jansen

Hey Nataraj,

i have the same problem.

First of all, your code seems to be correct.
I did it in the same way following the class despriction. When you set
the expiring date to one week (Date expires = new Date(new
Date().getTime() + (1000 * 60 * 60 * 24 * 7));) it will work and you
get a cookie.
I tried it for two and three weeks and it works. For four weeks it fails.

It looks like there is a problem with longer expiring dates
Does anyone have a solution?

Cheers!



2010/6/4 Nataraj M Basappa natara...@gmail.com:
 Hi all,
  Just been pondering my head over this piece of code.

 Date expires = new Date(new Date().getTime() + (1000 * 60 * 60 * 24 *
 30));
 Cookies.setCookie(token, token, expires);
 Cookies.setCookie(secret, secret, expires, localhost, /,
 true);
 Cookies.setCookie(uname, ram, null);

  Can anyone correct me. First two calls completely fail to set
 cookies, last one does set it but expiry time is set to
 current browser session. (looking at googles test code for last call
 should have set to never expire)

 Cheers!

Another feature for 2.1

2010-07-07 Thread Pavel Lahoda

Congrats to the new M2 of 2.1 release of the GWT framework.
Is there any chance that we'll see some progress in the area of making
GWT Java API subset more complete to the original libraries ?
To be specific : is there any chance, that Reflection API gets
implemented ? There are some projects that do just that, so it is
proof it can be done, just none of them is complete (I haven't seen a
project that would allow reflection of annotations in the runtime)
plus it would be great if such a standard feature of the language
makes it into standard distribution. Please, make this happen. Thanks.

HowTo maintain a dynamic list of widgets to be shown on page

2010-07-07 Thread Nirmal

HI,
I am designing an application with GWT2.1 which is comprised of a page
full of widgets.
The widgets to be shown on the page are based on the values in URL
parameters.

How to go about implementing this?
Primary motives:
1) Only code for the widgets to be displayed should be downloaded.
2) The applicable widget list should be maintained dynamically. So
that the list of widgets to be shown for given set of URL parameters
can be altered without having to redeploy the application.

Regards,
Nirmal

 With the latest versions of GWT you don't have to use any other
 libraries.

 GWT now comes with something known as Javascript Overlays that you can
 utilise to convert JSON into Objects.

 See here:

Re: Best way to style every other item?

2010-07-07 Thread Sean

I would extend Grid or Vertical Panel and on add or insert, update the

Removing would cause you to remove the widget, then update all the CSS
of the ones below the removed question.

 class to items; that seems better. Another option is to add a class like
 this manually when you add an item to the list, but then removing an item
 becomes a pain. Maybe there is a better way to do this automatically that I

Re: HowTo maintain a dynamic list of widgets to be shown on page

2010-07-07 Thread Thad

I'm not sure what you mean by #1.  GWT widgets are not server-side
objects.  They are created on the client side by client code.

That said, my I'm doing something similar to what you're looking at.
My application can add, edit, delete, and query for database records.
A table accessible by the client has a form definition which is kept
in XML on the server.  My approach is to ask the server (via an RPC
call) for a list of the forms.  Display the list.  When a user picks
one, I make an RPC request for the form.  When it's returned (as
text), I walk though the text and build GUI on the fly:  determine
form height and width and create an AbsolutePanel of that size; for a
text field, create a TextBox; for a label, a Label; for popup
selector, a ListBox; etc.  As each widget is created, place it on the
AbsolutePanel.

GWT 2.1 MVP Tutorial

2010-07-07 Thread Marco De Angelis

Hi all.

While GWT team is clearly working hard to promote 2.1 to more mature
releases, some documentation would had been of help in evaluating the
impact of the new design (MVP, Activity, cell-based components) on
existing projects. While experimenting with GWT's recent branches, I
decided to write down a few notes of what I (think I) may have
understood from existing examples.

You may find this first part of the tutorial on the Model/DTO at:

http://www.over-look.com/site/index.php/documentation/techblog/item/gwt-2-1-tutorial-1-mvp-the-model

I hope this introduction may help you, at least until more official
documentation is ready.

Re: gson module problem

2010-07-07 Thread lineman78

The easiest way to convert between JSON and GWT objects is to use
overlay objects.  Unfortunately, there is no type checking by doing
this, but you get the best performance.  Now, if you need to support
older versions of IE you will need to include json2.js in your
project, but you can use the JSON.parse and JSON.stringify functions
to convert between javascript objects and a JSON string.

Re: MVP Framework in GWT 2.1 M1 ?

2010-07-07 Thread Marco De Angelis

In M2, things have been cleaned up a bit. The framework has been moved
out of bikeshed into user folder, thus promoted into gwt.jar and out
of bikeshed.jar file (Bikeshed contains only the example apps now). If
you're using Roo, you have to fix the POM manually or wait for Roo M2
to be released (should happen this week).

I agree that Expenses contains a lot of hard-coded stuff. I believe
they wanted to show something impressive at Google I/O, focusing on
the core design separations (Activities, Places, RequestFactory,
Records), knowing that the API definition was not 100% clean nor
clear.

Just as an example, the left-side tree View is somewhat crumpled, as
it does not separate RequestFactory queries (which should take place
in an Activity) from the View. Also, Expanses Details views are fired
via direct calls instead of Places events, and so on.
But I am confident that the example will improve alongside with the
framework. Personally, I'm diving into what's available today. It's
better than nothing and gives me a good heads up on the changes.

On Jun 22, 9:33 am, Chris Boertien chris.boert...@gmail.com wrote:
 The one half of Expenses isnt even MVP. The one you access via
 Expenses.html is a hard-wired app. That is the one they were showing
 at Google I/O.

 The other part, the Scaffold app I believe is what Roo spits out found
 under Scaffold.html. I'm not sure as to just how much of that has been
 hand tweaked and how much is straight up codegen. Of course, all of
 that stuff is still under heavy development.

  I'm certainly not the best developer/architect going round, but I like

  This expenses example is a nightmare to follow.  The bindings/wiring

  I sure hope Spring Roo can generate an excellent CRUD starter
  application for me based off my domain objects and their
  relationships, cause there is no way in the world I could have come up

   You can see the code for activities and places here:

I just downloaded the M1 release ofGWT2.1and was wondering where I
can find more information on the MVP framework that will be part 
ofGWT2.1.
I looked around the Javadocs but did not find anything like it. Is the
MVP framework already part of the M1 release ?

how to solve it ?

 The easiest way to convert between JSON and GWT objects is to use
 overlay objects.  Unfortunately, there is no type checking by doing
 this, but you get the best performance.  Now, if you need to support
 older versions of IE you will need to include json2.js in your
 project, but you can use the JSON.parse and JSON.stringify functions
 to convert between javascript objects and a JSON string.

   Hi all,

   With the latest versions of GWT you don't have to use any other
   libraries.

   GWT now comes with something known as Javascript Overlays that you can
   utilise to convert JSON into Objects.

   See here:

  http://code.google.com/webtoolkit/doc/latest/DevGuideCodingBasicsOver...

   Also I have made a bit of a discussion on my blog here:

  http://eggsylife.co.uk/2010/04/22/gwt-2-jsonp-and-javascript-overlays...

   Hope this helps,

   Eggsy
