 Hi, im trying to dynamically embed a gwt module into an jquery
 application. In this application i have pages which contain gwt
 modules. In such an page, i simply add the gwt container div, the
 script (nocache.js) and the css tag to the html body code. The problem
 is, when i do that this way, the page gets loaded and disappears after
 the gwt module was loaded.
 Than i just get a blank page, with this script inside:
 script
 defer=deferandorialowlevelanimations.onInjectionDone('andorialowlevelani 
 mations')/
 script

 When i add the script tag and the div id to the main startpage, inside
 the head, (where jquery and other scripts get loaded) everything works
 fine. Can anybody tell me why this happens?

Because GWT generates document.write() calls in the *.nocache.js, and
document.write() on an already-loaded page implies document.open(),
which clears the document and replaces it with an empty one.
This is the default behavior though, you can change it by implementing
your own SelectionScriptLinker (extending IFrameLinker for instance)
generating a slightly different *.nocache.js.
You'll find several discussions on this group's archives about this
issue, and some people already went that road (I don't know if they
succeeded or gave up though)

Re: Gwt 2.1 Activities + Code splitting + Gin



On 8 nov, 21:42, PhilBeaudoin philippe.beaud...@gmail.com wrote:
 Thanks Thomas.

 So the way I understand it, the ActivityManager/ActivityMapper are GWT
 2.1 equivalent's of GWTP's proxy for the purpose of navigation. It's
 just that in GWTP you don't need to create or modify a separate class,
 all is done within your presenter.

 In my apps, I often have some presenters that need to be awoken when a
 given message transit on the bus. Say, for example, a ChatBoxPresenter
 would like to wake up when a NewChatMessageEvent transits on the bus.
 In GWTP it's simply a matter of annotating a method with @ProxyEvent
 in the presenter -- ChatBoxPresenter is still lazily instantiated and
 code split. How would you handle such a case in GWT 2.1 short of
 instantiating the ChatBoxPresenter at app start?

As I understand it, your ChatBoxPresenter isn't related to a place,
i.e. it's awoken based on a business event, not a navigation
event; and in other words, it's not an Activity: case made.
Activities (ActivityManager) is limited in scope to reacting to place
changes and navigation (not that you couldn't use the Activity
contract in other scenarios, such as your chat box, but the
ActivityManager wouldn't be the right tool for the job, you'd have to
find/write another activity manager for your different use case).

In other words: GWT 2.1 Activities won't replace GWTP as a whole (and
I believe, as I already said in the past, that it's not its goal
either).

Deploying GWT project on Tomcat

2010-11-09 Thread Pablo G.F

Hello:

I want to deploy a GWT project on a Tomcat server. As I´ve read, all I
have to do is compile the GWT project (by the option in Eclipse, for
example) and then (the app name is menutemplate):

- Create a directory on webapps (in the Tomcat path) with name, for
example, myapp.
- Copy war/menutemplate directory (output of compilation) into myapp.
- Copy menutemplate.html and menutemplate.css into my app.

Doing this, my app works, but If i add a service with a rpc call it
doesn´t. I suppouse I have to specify the servlets in the web.xml
which is on WEB-INF, but when I copy the WEB-INF into myapp directory,
then I cannot run the application.

Have I made any mistake during the process? or have I forgotten any
step?

Thanks

 I *think* that happens after you have fired a RequestContext. From

 So I think you need to use a new RequestContext.

Remove an Element from a Page

2010-11-09 Thread RRRaney

Hello,

I have an HTML page: HomePage.html
.
body id = ThePage
div id = TheItem
/div
/body

I also have several other HTML pages.

In my onModuleLoad
I would like to remove TheItem from ThePage


package my.client;

import com.google.gwt.core.client.EntryPoint;
import com.google.gwt.user.client.DOM;
import com.google.gwt.user.client.ui.RootPanel;

public class Application implements EntryPoint
{
@Override
public void onModuleLoad()
{
RootPanel x = RootPanel.get(ThePage);
DOM.removeChild(x.getBodyElement(),
DOM.getElementById(TheItem));

}
}

This is not working.

If I have Only one HTML Page the following seems to work.

public class Application implements EntryPoint
{
@Override
public void onModuleLoad()
{
DOM.removeChild(RootPanel.getBodyElement(),
DOM.getElementById(TheItem));

}
}


Any ideas on how to remove a specific item from a specific page would
make my day.

Thanks,

Raney

 On Nov 8, 8:20 pm, David Chandler drfibona...@google.com wrote:







  Hi dparish,

  There are three issues here:

  1. GWT needs a fully populated object graph to send back to the
  client. Lazy fetching will not work across the client / server
  boundary, so you must ensure that your code fetches all relations
  eagerly (via an annotation or a separate call if needed).

  2. JDO and JPA implementations use proxy classes for objects attached
  to a persistence manager. Before they can be sent back to the client,
  you must detach all objects from the PM.

  3. Even then, GWT won't be able to serialize any types for which it
  doesn't know the source (like App Engine's Key class). The open source
  Gilead project and others like Objectify provide GWT wrappers for
  these.

Re: GWT and Google Maps API

Sure, I have already taken a deep look at the API libraries and even

Currently I am able to create a route between two addresses and

This polyline has n vertexes.

Now I am pondering about how to move a graphical object along this
polyline at a given speed.

Any advices?

  The way I imagine it right now is that I want to define a startpoint
  and an endpoint. Either by GPS Coordinates (xx° yy' zz'') or by an
  address (f.e. City, Street, Number) for every car.
  Then I would like Google Maps to calculate the route between the start
  and endpoint. (Preferably the shortes route)
  Last but not least a graphic symbol - at least a colored dot - should
  simulate the driving of a vehicle from the start point to the end
  point. This should occur in realtime and in addition simulated at lets
  say 500% of the normal speed. Some kind of a simulation mode.
  Of course the dot - the car - should move along the streets and not
  directly from start to end.

  Is this possible using GWT and the Google Maps API?
  Can anyone point out best practices, maybe even existing samples?

  Thanks in Advance for both your time and your help!

Re: OpenJPA GWT serialization problem.

2010-11-09 Thread dparish

Thanks David.

I tried LAZY and EAGER. Both caused the problem.

For #2, that seems promising. There's an EntityManager clear method,
but that would affect all threads using the entity manager.  Any
thoughts on how to do that detach?

On Nov 8, 8:20 pm, David Chandler drfibona...@google.com wrote:
 Hi dparish,

 There are three issues here:

 1. GWT needs a fully populated object graph to send back to the
 client. Lazy fetching will not work across the client / server
 boundary, so you must ensure that your code fetches all relations
 eagerly (via an annotation or a separate call if needed).

 2. JDO and JPA implementations use proxy classes for objects attached
 to a persistence manager. Before they can be sent back to the client,
 you must detach all objects from the PM.

 3. Even then, GWT won't be able to serialize any types for which it
 doesn't know the source (like App Engine's Key class). The open source
 Gilead project and others like Objectify provide GWT wrappers for
 these.

Re: Entire Site in GWT?

2010-11-09 Thread mike.cann

Hi Guys,

Thanks for all the tips, im certainty going to take them on board when
I make my choice.

Im pretty sure im going to go with GWT now. The next step is to choose
my server architecture.

I really would like to have gone with GAE however I have done some
research and read it cant handle files  1mb in size. As I need to do
some image manipulation involving merging several 1mb PNGs into larger
ones I think im going to be stuck if I use GAE.

So my next question is does GWT play nice with other technologies and
if so which do people recommend?

I hope I haven't outstayed my welcome on this list!

Cheers,

  As a Flash / Flex developer new to web-dev im loving the extra

  exclusively for a new project.

  So my questions are:

  Is GWT suitable for writing an entire website? Specifically im looking
  to write a site that may sit within a Facebook iframe.

  Has the GWT isnt web-crawlable issue been solved now?

  Is the script for every page on your site downloaded at the start or
  is it downloaded as you click a link (as in a traditional site)?

  Are there any other barriers to making an entire site in GWT?

 In a nutshell, make sure you have all the required plugins from the
 README, copy the Expenses POM to your project, and eliminate unneeded
 dependencies. If not using App Engine, you should be able to use
 gwt-maven-plugin version 2.1.0 from Maven Central instead of the
 1.3.2.google version in the POM. And you can remove all the Spring
 deps if you're not using Spring.

 Does that help?

Re: Deploying GWT project on Tomcat

2010-11-09 Thread Chad

After you compile your project, go into the war folder and zip up the
contents of that folder. Name the zip file something.war where
something will be what you want your url to be. So, if you are
deploying to www.milamade.com, and named your war file dtrac.war, your
app would be available at www.milamade.com/dtrac. Now, copy your war
file to the webapps folder of your Tomcat server. The first time you
do that, Tomcat will automatically extract it and create the necessary
folder for you. When redeploying, you will still copy the new war file
to the same location (overwriting the old one), but then you will need
to run Tomcat manager and choose to reload the app.

HTH,

 Hello:

 I want to deploy a GWT project on a Tomcat server. As I´ve read, all I
 have to do is compile the GWT project (by the option in Eclipse, for

 - Create a directory on webapps (in the Tomcat path) with name, for
 example, myapp.
 - Copy war/menutemplate directory (output of compilation) into myapp.
 - Copy menutemplate.html and menutemplate.css into my app.

 Doing this, my app works, but If i add a service with a rpc call it
 doesn´t. I suppouse I have to specify the servlets in the web.xml
 which is on WEB-INF, but when I copy the WEB-INF into myapp directory,
 then I cannot run the application.

 Have I made any mistake during the process? or have I forgotten any
 step?

Re: RequestFactory - A request is already in progress

2010-11-09 Thread Tobias

I *think* that happens after you have fired a RequestContext. From
looking at the code, which is a bit hard because of the
DeferredBinding that's going on there, the locked variable in a
RequestContext gets only reset to false, if the fired Request fails.
So I think you need to use a new RequestContext.

Tobias

If you want to use the Google Plugin for Eclipse to run DevMode

http://code.google.com/eclipse/docs/faq.html#gwt_with_maven
We use a special devmode profile in our (multi-module) project so
that mvn package -Pdevmode actually means mvn war:exploded -
Dmaven.test.skip=true -Dgwt.compiler.skip=true on the web app module,
to speed things up (don't compile and run tests, don't compile client

For our project we use Tomcat / Postgresql on server side. It works great.
The hardest part is to be able to configure maven (if you use it) with gwt +
wtp (eclipse tomcat plugin). But with the latest version of all the eclipse
plugins, it should work fine.

+site#4b1d9c08a91e25ab) so I thought I would ask it again in case
anything has changed.

As a Flash / Flex developer new to web-dev im loving the extra
structure and type safety offered by GWT so im really keen to use it
exclusively for a new project.

So my questions are:

Is GWT suitable for writing an entire website? Specifically im looking
to write a site that may sit within a Facebook iframe.

Has the GWT isnt web-crawlable issue been solved now?

Is the script for every page on your site downloaded at the start or
is it downloaded as you click a link (as in a traditional site)?

Are there any other barriers to making an entire site in GWT?

Cheers,
Mike

Re: can't import into eclipse using mojo.codehaus.org gwt-maven-plugin 2.1.0

2010-11-09 Thread cri

Upon further experimentation, I'm under the impression that version
2.1 of the gwt-maven-plugin described at 
http://mojo.codehaus.org/gwt-maven-plugin/
is not really ready for general use. I found at least two
configuration defects in it. My recollection is a little vague
regarding the specific problems. One had to do with an incorrect
package specification having to do with Message class generation. The
other was a missing classpath entry for some generated classes, one of
which was Messages.java I think. I don't think that there has been a
general announcement that this plugin is really ready for use. I'll be
holding off using it for a while and just stick with standard gwt
generated projects. I did get quite a way with the plugin and it is
looking pretty promising.

 So, I suspect this is problem with the repository.

Simple XML Reader Problem

2010-11-09 Thread EK88

Hello there, first post here.

I've been trying to get my head around how to load an XML file from
file (ill deal later with actually uploading it to the server via the
interface) and here's what I've got from reading different posts on
the net, as well as the Simple XML Reader sample.

package com.moodlequizeditor.project.domparser;

import com.google.gwt.user.client.HTTPRequest;
import com.google.gwt.user.client.ResponseTextHandler;
import com.google.gwt.xml.client.Document;
import com.google.gwt.xml.client.XMLParser;


package com.moodlequizeditor.project.domparser;

import com.google.gwt.user.client.HTTPRequest;
import com.google.gwt.user.client.ResponseTextHandler;
import com.google.gwt.xml.client.Document;
import com.google.gwt.xml.client.XMLParser;



public class DomMain {

public static void main() {

HTTPRequest.asyncGet(myxml.xml, new ResponseTextHandler() {
public void onCompletion(String responseText) {
try {
Document document = 
XMLParser.parse(responseText);
new XMLLoad(document);

} catch (Exception e) {
e.printStackTrace(System.err);
}

}
});
}
}


For some reason though, it's not reading 'myxml.xml' (I've put it
literally everywhere in my structure) but I get the following in
console:

[WARN] 404 - GET /com.moodlequizeditor.project.MoodleQuizEditor/

Evaluating GWT 2.1 - Dynamic Module Loading

2010-11-09 Thread mesx

Hello Community!

im just evaluating GWT for our new projects and im currently planing
to re-write a huge project that is originaly written in pure
javascript (with some Javascript Frameworks) and a Java Servlet.

To do that in GWT i need the possibility to dynamically load GWT
modules.
I know, it is not a new idea and there are many threads about this
topic arround this forum group, but some of them are very old and some
of them are more about YAGNI-principle  (You ain't gonna need it)

I would like to know how to do this in the current GWT 2.1 version -
or is it even possible?
I read some articles which said that its not possible in 2.0 any more
- is this correct?

Some background information about our project:
At the top, there is a management application, that has the
possibility to start several sub-applications and provides useful
posibilities to these sub-applications.
A sub-application is installed to the management application by an
XML file that was read by a Servlet.
The XML contains many meta informations about the sub-apps and the
URLs to the js files.
For security reasons, not every user is able to start all sub-
applications, so the Servlet also checks permissions and so on...

With GWT we want to do a little re-design:
A default boot-module is loading the sub-Application files dynamically
(as needed) via AJAX and executes their defined boot-methods (defined
in interfaces) to start the sub-apps.

Is this possible in GWT?

Thanks in advance!!!

regards
Manuel

Re: Reload CellTable data

2010-11-09 Thread Pol-Za

 Is there an easy way to do something likecellTable.reload() 
 orcellTable.refresh() ?
cellTable.redraw() call the method cellTable.setRowData(int
startIndex, ListT ListValues)
when you update your data, next simply call cellTable.setDataRow(0,
ListValues) where 0 is first value in ListValues

enum for proxy in mvp framework

2010-11-09 Thread Gabriel

I need to expose an enum java type in the client side, is this
possible to do without a proxy?

I tried with:

package com.foo.client.managed.activity;

public class DeviceEditActivityWrapper implements Activity{

  public interface ViewV extends ProxyEditViewDeviceProxy, V
extends ProxyEditViewDeviceProxy, V {
  void setTypePickerValues(CollectionType values);
  }
...
  public void start(AcceptsOneWidget display, EventBus eventBus) {
view.setTypePickerValues(Arrays.asList(Type.values()));
wrapped.start(display, eventBus);
  }

}

But this throw a error because the Type class is located server
package inside.

CheckboxCell as SelectionModel provider

2010-11-09 Thread Baloe

Hi all,

I'm trying to get a CheckboxCell working as a selector for the row,
but it doesn't work. And there is no getValue() on the CheckboxCell as
well, so any weird saving of added checkboxes is no alternative as
well.

The code is as follows:
...
cellTable = new CellTableDtoContactList();
cellTable.setSelectionModel(new
MultiSelectionModelDtoContactList());

flowPanel.add(cellTable);

cellTable.addColumn(new ColumnDtoContactList, Boolean(
new CheckboxCell(true)) {
@Override
public Boolean getValue(DtoContactList object) {
return false;
}
}, new TextHeader(Select));
...
Because it says 'true' in the CheckboxCell, it should function as a
selection controller, right? Well, it doesn't:

@Override
public ListDtoContactList getSelected() {
MultiSelectionModel? super DtoContactList model =
(MultiSelectionModel? super
DtoContactList) cellTable.getSelectionModel();
LOG.log(Level.INFO, selected size= +
model.getSelectedSet().size());

Thanks for any hints!

Baloe

The maven eclipse plugin should include the GWT SDK which is set as
default in your project this way. One minor obstacle remains though:
when running the debugger (developer mode) in eclipse it looks for

generic service interfaces

2010-11-09 Thread heiko

Hello,

i'm trying to implement a 'Command Pattern' in my application, as
suggested in  'Best Practices For Architecting Your GWT App' (http://
www.google.com/intl/de-DE/events/io/2009/sessions/GoogleWebToolkitBestPractices.html).

I've been looking at gwt-dispatch and have taken some inspirations
from it, but i want to make my own for educational reasons.
Now i'm having a problem with the service interfaces for what shall be
my 'Command Service' (where all the different types of actions are
assigned to specific handlers / responses for that action).

The project builds fine in eclipse, but as soon as i access my
application (i run it in development mode) i get the following errors
(via the Development Mode Tab in eclipse; similar errors occur when i
try to gwt-compile):


16:18:20.498 [ERROR] [spi_gwt] Line 11: The type CommandService_Proxy
must implement the inherited abstract method
CommandServiceAsync.execute(A, AsyncCallbackT)

16:18:20.529 [ERROR] [spi_gwt] Line 23: Name clash: The method
execute(Action, AsyncCallback) of type CommandService_Proxy has the
same erasure as execute(A, AsyncCallbackT) of type
CommandServiceAsync but does not override it

and thus

16:18:20.607 [ERROR] [spi_gwt] Deferred binding failed for
'de.leo.spi.client.services.CommandService'; expect subsequent
failures

now my question is, what am i doing wrong here? i've defined and
implemented other services (that were not generic) earlier, and never
had no such problems.



heres how my service interfaces look like:

/
*---
*/
package de.leo.spi.client.services;

import com.google.gwt.user.client.rpc.RemoteService;
import com.google.gwt.user.client.rpc.RemoteServiceRelativePath;

import de.leo.spi.shared.action.Action;
import de.leo.spi.shared.response.Response;


@RemoteServiceRelativePath(command)
public interface CommandService extends RemoteService{

T extends Response, A extends ActionT T execute(A action);
}



/
*---
*/
package de.leo.spi.client.services;

import com.google.gwt.user.client.rpc.AsyncCallback;

import de.leo.spi.shared.action.Action;
import de.leo.spi.shared.response.Response;

public interface CommandServiceAsync {

T extends Response, A extends ActionT void execute(A action,
AsyncCallbackT callback);
}

GWT 1.5.3 + Liferay 5.1.2 : Internationalisation Issue

2010-11-09 Thread pn

Hi,

I am unable to get GWT 1.5.3 internationalisation working for a GWT
app running inside a portlet inside Liferay 5.1.2. and I am hoping
someone can help me. I am using German as a test language for some of
my strings. I have everything setup what I think is correctly but all
I see is the default (English) language on my application, even though
GWT generates the german version of the *.cache.html files and I can
see the checking for the german locale in the *.nocache.js file.

I have made the following changes to my application to support
Internationalisation:

1. Added an AppMessages_de.properties file containing the german
strings. This is in the same client package as the AppMessages.java
class which is defined as:

public interface AppMessages extends Messages {

The messages are instantiated as:

messages = (AppMessages) GWT.create(AppMessages.class);


2.  Updated my App.gwt.xml:

 Added:
inherits name=com.google.gwt.i18n.I18N/
extend-property name=locale values=de/

Complete File:
module
inherits name='com.google.gwt.user.User'/
inherits name='org.gwtwidgets.WidgetLibrary'/
inherits name=com.google.gwt.i18n.I18N/
extend-property name=locale values=de/
inherits name=com.thapar.gwt.user.ui.SimpleDatePicker/
entry-point class='mycompany.myproduct.portlet.rvui.client.App'/

servlet path='/download'
class='mycompany.myproduct.portlet.rvui.server.servlet.FileDownloadServlet'/

servlet path='/upload'
class='mycompany.myproduct.portlet.rvui.server.servlet.FileUploadServlet'/

servlet path='/logout'
class='mycompany.myproduct.portlet.rvui.server.servlet.LogoutServlet'/

servlet path=/servlet/streamServiceServlet
class=mycompany.myproduct.portlet.rvui.server.rpc.StreamServiceImpl /

stylesheet src='App.css'/
/module

3. Updated my App.html file to add the meta tag for the locale in
between the head/ tags:

meta name=gwt:property content=locale=de


So, as mentioned, GWT successfully creates the German *.cache.html
files and I can see the German strings defined in these files but for
some reason, the locale setting is not getting through the app to
cause it to use the correct German version.

Any help would be very much appreciated.

Thanks a lot.

Re: Reload CellTable data

when you need refresh data from cellTable simply call
cellTable.setRowData(0, ListValues) where ListValues contains your
changed data

Below code fragment of implementation redraw()
// package com.google.gwt.user.cellview.client

The data from an external URL should be displayed in a GWT tab widget.

2010-11-09 Thread skippy

The data from an external URL should be displayed in a GWT tab widget.
The parameters to the external URL, varies depending upon user
preferences.
This  URL  returns javascript code, that has to be embedded in
script tag on GWT side so that the browser executes it  to display
the appropriate data.

Embedding the javascript response in GWT, using a script tag,
within the existing tab widget,  is not rendering the script properly
in Mozilla, whereas IE does not execute the script at all.


Any ideas would be great!

Thanks for all the tips, im certainty going to take them on board when
I make my choice.

Im pretty sure im going to go with GWT now. The next step is to choose
my server architecture.

So my next question is does GWT play nice with other technologies and
if so which do people recommend?

I hope I haven't outstayed my welcome on this list!

So my questions are:

Is GWT suitable for writing an entire website? Specifically im looking
to write a site that may sit within a Facebook iframe.

Has the GWT isnt web-crawlable issue been solved now?

Is the script for every page on your site downloaded at the start or
is it downloaded as you click a link (as in a traditional site)?

Are there any other barriers to making an entire site in GWT?

Re: CheckboxCell as SelectionModel provider

 Hi all,

 I'm trying to get a CheckboxCell working as a selector for the row,
 but it doesn't work. And there is no getValue() on the CheckboxCell as
 well, so any weird saving of added checkboxes is no alternative as
 well.

 The code is as follows:
 ...
                 cellTable = new CellTableDtoContactList();
                 cellTable.setSelectionModel(new
 MultiSelectionModelDtoContactList());

                 flowPanel.add(cellTable);

                 cellTable.addColumn(new ColumnDtoContactList, Boolean(
                                 new CheckboxCell(true)) {
                         @Override
                         public Boolean getValue(DtoContactList object) {
                                 return false;
                         }
                 }, new TextHeader(Select));
 ...
 Because it says 'true' in the CheckboxCell, it should function as a
 selection controller, right?

No.

 Thanks for any hints!

See http://gwt.google.com/samples/Showcase/Showcase.html#!CwCellTable
// Checkbox column. This table will uses a checkbox column for
selection.
// Alternatively, you can call cellTable.setSelectionEnabled(true)
to enable
// mouse selection.
ColumnContactInfo, Boolean checkColumn = new ColumnContactInfo,
Boolean(
new CheckboxCell(true)) {
  @Override
  public Boolean getValue(ContactInfo object) {
// Get the value from the selection model.
return selectionModel.isSelected(object);
  }
};
checkColumn.setFieldUpdater(new FieldUpdaterContactInfo,
Boolean() {
  public void update(int index, ContactInfo object, Boolean value)
{
// Called when the user clicks on a checkbox.
selectionModel.setSelected(object, value);
  }

Re: gwt-dnd

2010-11-09 Thread ciosbel

Of course it is possible.
See live demos 
http://allen-sauer.com/com.allen_sauer.gwt.dnd.demo.DragAndDropDemo/DragAndDropDemo.html
The demo 8 should tell you how (see java sources).

I think you have to tell the drag controller to make a given panel
draggable by a given child.
i.e.

// make the panel draggable by its header
dragController.makeDraggable(verticalPanel, header);

Hope that helps.

 I am a little confuse.
 Is possible to make this with gwt-dnd?

 The way I did following some examples when I click in a textbox, or a

 Any advice?

Yes, you need:

 2. this gwt.xml to include the enum in the source path, e.g. source

Retrying requests in case of Multiple requests to RPC servlet

2010-11-09 Thread swingm

Can help me how to write Retry logic for requests in order avoid 500
server if there are simultaneous requests.

I'm thinking of implementing a workaround with a custom
RequestBuilder. RequestBuilder.send() would start a Timer timing out
after 300ms. On timeout it would abort the request and send a new
request. Hopefully this will cancel IE's behaviour of resending the
request with a missing body.

uibinder and nested layout

2010-11-09 Thread Sachin Dole

Hello,

I have a requirement for an HTML page with a top horizontal header bar, a
large middle panel that will itself contain the left navigation column, a
middle content panel and a right side margin for showing Associated
content. At the bottom is a footer with its own content. To lay this out, I
want to use UiBinder. How do I nest UiBinder fields? In other words, how to
refer to @UiFields that are declared not in the main outer page class but in
classes that are @UiFields of the main page class? Is it even possible to
nest UI classes into one layout?

Thank you list!

Re: GWT 2.1 RequestFactory and complex properties on my DTO (Entity proxies)

2010-11-09 Thread koma

I guess this is the relevant part :

A new Proxy interface will be added as a superclass of ValueProxy
and EntityProxy to allow RequestFactory.create to operate on both
value and entity types.
Because ValueProxy doesn't have a stableId() method, there's no way to
use a VP with a call to find() or with any other service method that
has an EntityProxyId argument.
If you think about a Date object, there's no real meaning in giving a
Date an id.
If an EntityProxy has a value property, all of the properties of the
VP are checked for mutations and sent to the server.
The value in the domain object will be replaced if anything in the
VP's state has changed.

Deferred Binding with interfaces

2010-11-09 Thread Thalles

Hello group,

I've just got a quick question. Is it possible to do deferred binding
with interfaces?
Background: I would like to change the client bundle or constants
interfaces, depending on the user.
The problem is, that the client bundle or constants implementation has
to be an interface itself.

I've tried to implement it, but it always says Deferred binding
result type classname should not be abstract

This is my general class, that should be replaced:
public interface MyResources
{
  public static final MyResources INSTANCE =
GWT.create(MyResources.class);

  CssResource css();
  TextResource getSynchronousTextResource();
  ExternalTextResource getAsynchronousTextResource();
  ImageResource getDLRLogo();
}

Here is one of implementations
public interface GoodByeResources extends ClientBundle, MyResources {
  public static final GoodByeResources INSTANCE =
GWT.create(GoodByeResources.class);

  @Source(files/test.css)
  CssResource css();

  @Source(files/test1.txt)
  TextResource getSynchronousTextResource();

  @Source(files/test2.txt)
  ExternalTextResource getAsynchronousTextResource();

  @Source(files/dlk.jpeg)
  ImageResource getDLKLogo();
}

Here is a usage example:
ImageWindow cmdw = new ImageWindow(myConstants.caption(),
MyResources.INSTANCE.getDLKLogo());

And this is my configuration:
   replace-with class=gwt.map.client.constantstest.HelloResources
when-type-is class=gwt.map.client.constantstest.MyResources/
when-property-is name=alerter value=hello/
  /replace-with

  replace-with class=gwt.map.client.constantstest.GoodByeResources
when-type-is class=gwt.map.client.constantstest.MyResources/
when-property-is name=alerter value=goodbye/
  /replace-with


Is there any way, I could do this? Maybe a concrete class with an
inner interface?
Can I inject interfaces with GIN?

Thanks in advance!

Bye Thalles

Re: CellTree reordering nodes?

Right now I'm really happy because it is just that little bit less

 The really strange thing is that if I do .add(0, Object), then

Re: Deferred Binding with interfaces

2010-11-09 Thread Jeff Larsen

The easiest way would be to do this with GIN and a provider method.

I'm not sure what the when-property-is name=alerter
value=goodbye, so I could be off base here, but here is a way to do
it.

@Inject
@Provides
public MyResources getMyResources(MyResources hello, GoodByeResources
goodBye,  Alerter alerter){
if(alerter.equals(hello)){
 return hello;
}else if(alerter.equals(goodbye)){
 return goodBye;
}
}

Also, MyResources needs to extend ClientBundle, and then by extendsion
GoodByResources automatically does.

Then you can just @Inject MyResources and it will make the decsion as
to which resource bundle to return.

Hi Jeff

I can't be authoritative on best practice, however I've got a few
widgets that wrap GWT widgets (TextBox and ListBox) which edit simple
values such as Strings and Integers.
I just make them implement LeafValueEditorT and they work in the
same way as a GWT widget does with the editor framework.

For example :

public class CharField extends FormRow implements
LeafValueEditorString {
..
@Override
public String getValue() {
return tb.getValue();
}

@Override
public void setValue(String value) {
setValue(value, false);
}
}


Cheers

Will

Re: OpenJPA GWT serialization problem.

2010-11-09 Thread David Chandler

In JDO, there are pm.detachX() methods you can use to do this. In JPA,
it appears detachment is automatically done via an annotation, but the
detached objects will still contain non-serializable stuff. Details
here:

 I tried LAZY and EAGER. Both caused the problem.

 For #2, that seems promising. There's an EntityManager clear method,
 but that would affect all threads using the entity manager.  Any
 thoughts on how to do that detach?

 Hi dparish,

 There are three issues here:

 1. GWT needs a fully populated object graph to send back to the
 client. Lazy fetching will not work across the client / server
 boundary, so you must ensure that your code fetches all relations
 eagerly (via an annotation or a separate call if needed).

 2. JDO and JPA implementations use proxy classes for objects attached
 to a persistence manager. Before they can be sent back to the client,
 you must detach all objects from the PM.

 3. Even then, GWT won't be able to serialize any types for which it
 doesn't know the source (like App Engine's Key class). The open source
 Gilead project and others like Objectify provide GWT wrappers for
 these.

 On Oct 29, 6:57 am, David Chandler drfibona...@google.com wrote:
 Gene,

 Thank you for your thoughtful questions. As you have observed,
 Activities and Places do not directly support nesting, but there are a
 couple different ways you can implement compositeviews:

 1) An ActivityManager is responsible for swapping activities within
 one container widget; however, you can have multiple ActivityManagers,
 each with its own ActivityMapper and container widget. Suppose your
 application's main widget is a DockPanel with a westPanel and
 eastPanel. You would then have something like this:

 DockLayoutPanel dockLayoutPanel = new DockLayoutPanel(Unit.PCT);
 SimplePanel westWidget = new SimplePanel();
 SimplePanel eastWidget = new SimplePanel();

 WestActivityMapper westActivityMapper = new WestActivityMapper();
 WestActivityManager westActivityManager = new
 WestActivityManager(westActivityMapper, eventBus);
 westActivityManager.setDisplay(westPanel);

 EastActivityMapper EastActivityMapper = new EastActivityMapper();
 EastActivityManager eastActivityManager = new
 EastActivityManager(eastActivityMapper, eventBus);
 EastActivityManager.setDisplay(eastPanel);

 dockLayoutPanel.addWest(westWidget, 50);
 dockLayoutPanel.addEast(eastWidget, 50);
 RootLayoutPanel.get().add(dockLayoutPanel);

 PlaceMapper and PlaceHistoryHandler would be initialized the same as
 in the HelloMVP example.

 In this design, the WestActivity could call
 placeController.goTo(detailPlace), where DetailPlace is mapped only in
 the EastActivityMapper so the westPanel won't change. Alternatively,
 the EastActivityMapper and WestActivityMapper can each map the same
 Place to a different Activity, in which case the Activities in both
 panels will change. This is one way to implement a composite Place.

 2) There is not necessarily a 1:1 correspondence between Activities
 and presenters. Your Activity might instantiate multiple presenters
 and correspondingviews. When the Place changes, the whole composite
 Activity will be swapped out, and, as you pointed out, this will
 result in setWidget() being called on the ActivityManager's container
 widget. However, if activities and presenters obtain theirviewsfrom
 a factory as in the HelloMVP example, this should not be noticeable,
 asviewsobtained from the factory would not be reconstructed.

 Does that help? We welcome community feedback on what works best.

  Hi,

  I have been reading the excellent article at:
 http://code.google.com/webtoolkit/doc/latest/DevGuideMvpActivitiesAnd...

  And love the new built in objects that facilitate the MVP design
  paradigm.  My initial thought is great but how does this system cope
  withNestedViewsor Dock Panel style layouts where various elements
  can be clicked and the widget that changes isn't necessarily always
  the center one?

  Looking at the example code given for HelloMVP it looks like when you
  go to a new Place when the Activity is started by calling the start
  method a widget is passed in that is the containerWidget or host for
  that presenter:

        �...@override
         public void start(AcceptsOneWidget containerWidget, EventBus
  eventBus) {
                 GoodbyeView goodbyeView = clientFactory.getGoodbyeView();
                 goodbyeView.setName(name);
                 containerWidget.setWidget(goodbyeView.asWidget());
         }

  Looking at the setup code from the onModuleLoad, a root SimplePanel is
  added to the activity manager:

  activityManager.setDisplay(appWidget);

  This widget is then passed to the start method each time a new place
  is revealed.  Thus causing a screen refresh?  each time a new place is
  revealed.

  How would you handle a scenario that has a Left hand menu (like gmail)
  and a main container.  Where clicking options in the LHS initiates a
  new widget to be displayed in the center.  Using the current logic it
  looks like the whole screen is refreshed to show the newly selected
  menu option and the center widget.  Perhaps it does, and perhaps this
  is ok, but it sounds hacky.

  For example it would be nice if clicking a center widget not only
  indicated what place to reveal but where that place/widget should be
  revealed?

  I am sure this scenario is very common and it may have a lot to do
  with my naivety with this new methodology.  If anyone has any
  pointers, opinions or examples on this it would be greatly
  appreciated.

Setting Specific PieChart Color Slices

2010-11-09 Thread Killian

Hi lads,

First of all apologies if this isn't the correct discussion group to
answer this query. I have been looking for the gwt visualization api
group to no avail.

My query is quite simple. I am trying to find a way to set the color
of specific slices inside a PieChart object. It seems to be possible
to do in js.
http://code.google.com/apis/visualization/documentation/gallery/piechart.html
pieSliceTextStyle |  {color: string, fontName: string, fontSize:
number}

Hence I'm wondering if the same thing is possible with the gwt version
of the piechart?

The only way I found to do this in the gwt version of PieChart is by
doing the following:
options.setColors( #3399FF,#80C080,#008000,#80);
But unfortunately this assigns colors randomly to slices. Hence I
can't control the color of particular slices

Is there any way of doing this?

Thanks for your help in advance

FormPanel: why it extends SimplePanel?

2010-11-09 Thread pash7ka

Is there a good reason for FormPanel to extend SimplePanel and not
some other panel (like HTMLPanel)?
The problem with SimplePanel is the restriction to only one child,
while most forms contain much more fields. So one shoud use some other
Panel whithin the Form and this leads to unnecessary markup.

When using a MultiSelectionModel on a CellList should I be able to deselect an item in the CellList?

I've created a CellListString with a MultiSelectionModelString and
it seems to work correctlty in that it allows the user to select
multiple items and I can programmatically retrieve the selected items.

But, when trying to deselect an item the item does not deselect.

Is there something that I'm missing to get this behavior?

Currently, you can only selected rows, you can't deselect them.  User

How to use JSONObject with common code shared between client and server

2010-11-09 Thread Kashif

Hi everyone,

I have a class that I want to share both with client and server code,
in my particular case it's the JSONObject.

It has different implementations on client
(com.google.gwt.json.client.JSONObject) and server
(org.json.JSONObject), but same interface.

So I have a DTO class like this shared between client and server, so I
can use JSON to pass objects around and wrap them in JSONObjects for
easy API access:

class Person {

String firstName;
String lastName;

public JSONObject toJson()
{
   // code to convert firstname + lastname to JSON
}

public fromJSON (JSONObject x)
{
   // code to read from JSONObject and set firstName and lastName
}
}

There is no way for me to tell GWT to use
com.google.gwt.json.client.JSONObject when compiling this class on
client, and likewise use org.json.JSONObject on server. I would have
to resort to Java String.

Now I could do the following, but I would have to re-write the toJson/
fromJson methods for each implementation -  not acceptable to me!

class PersonBase
{
  String firstname;
  String lastname;
}

class Person_Client extends PersonBase
{
public fromJSON (om.google.gwt.json.client.JSONObject x)
{
   // code to read from JSONObject and set firstName and lastName
}

public com.google.gwt.json.client.JSONObject toJson()
{
   // code to convert firstname + lastname to JSON
}
}

class Person_Server extends PersonBase
{
public fromJSON (org.json.JSONObject x)
{
   // code to read from JSONObject and set firstName and lastName
}

public org.json.JSONObject toJson()
{
   // code to convert firstname + lastname to JSON
}
}

There must be an easier way!

Re: RPC version mismatch on client server

2010-11-09 Thread notcourage

Thx for the reply  your blog post taught me more about gwt. Here's
another idea: assign the app a version#. Assign this value to a
variable in the client  server. Every rpc passes the client's
variable. When there is a mismatch, the server throws
AppVersionException. To minimize the chance the user submits a big
form only to be asked to reload the app: if the app hasn't been used
in awhile, the app calls an rpc which checks for a version mismatch.

On Nov 8, 1:06 pm, Stephen Haberman stephen.haber...@gmail.com
wrote:
  Scenario: A user is running version n-1 of a gwt app. Meanwhile,

  What's the best way to address this?

 If you use IsSerializable (and no type name elision), and don't have
 any actual API changes, you'll be okay, you user shouldn't notice.

 Otherwise you'll have to catch IncompatibleRemoteServiceException and
 ask your user to reload the app.

 I was mulling over this scenario awhile ago and wrote a blog post about
 it:

Re: Including jQuery in GWT

2010-11-09 Thread ciosbel

I don't know if it's helpful or (given your already coded js) usable,
but there is a clone of jquery for gwt. It's called GQuery.
Take a look http://code.google.com/p/gwtquery/

On 9 Nov, 21:58, Yaakov yaakov.chai...@gmail.com wrote:
 Hi,

 I have a page that a web designer produced and now I need to add GWT
 into it.

 I placed the contents of the HTML between body (not including it)
 into a uiBinder g:HTMLPanel/g:HTMLPanel.

 In the host page, I have some headers that refer to jQuery and
 javascript that the designer wrote, like this:
   head
     link rel=stylesheet type=text/css href=resources/css/
 styles.css /
     script type=text/javascript src=resources/js/
 jquery.tools.min.js/script
     script type=text/javascript src=resources/js/application.js/
 script
     script type=text/javascript language=javascript
 src=keyImportActivity/keyImportActivity.nocache.js/script
     /head

 Some of the visual affects that the designer used are from jQuery and
 the way these get bound to some HTML elements are through a jQuery-
 specific window.onLoad function $(function(){ some bindings here});

 Here is the code from that application.js referred to above in the
 head:
 $(function() {

     setButtonClasses(buttonPlus);
     setButtonClasses(buttonMinus);
     setButtonClasses(buttonRefresh);
     setButtonClasses(buttonAdmin);
         setButtonClasses(buttonImports);
     setButtonClasses(buttonInventory);
     setButtonClasses(buttonSignOut);
         setButtonClasses(buttonNewer);
         setButtonClasses(buttonOlder);
         setButtonClasses(sortAscending);
         setButtonClasses(sortDescending);

     $(div.buttonPlus).click(leftNavigationHandler);
         $(a.lightbox).click(doPopup);

 });

 So, this doesn't work. My guess, this is because it gets called BEFORE
 GWT even builds those buttons, etc., so at the time it supposedly gets
 called, these elements don't exist yet or at least are not guaranteed
 to exist yet.

 So, I changed this onLoad function and made it a regular function
 like this:
 function bindjQuery() {
         alert(Inside JS bindjQuery);
     setButtonClasses(buttonPlus);
     setButtonClasses(buttonMinus);
     setButtonClasses(buttonRefresh);
     setButtonClasses(buttonAdmin);
         setButtonClasses(buttonImports);
     setButtonClasses(buttonInventory);
     setButtonClasses(buttonSignOut);
         setButtonClasses(buttonNewer);
         setButtonClasses(buttonOlder);
         setButtonClasses(sortAscending);
         setButtonClasses(sortDescending);

     $(div.buttonPlus).click(leftNavigationHandler);
         $(a.lightbox).click(doPopup);

 }

 Now, in my EntryPoint, I have this:
 public class KeyImportActivityEntryPoint implements EntryPoint {

         public void onModuleLoad() {
                 KeyImportWidget keyImportWidget = new KeyImportWidget();
                 RootLayoutPanel.get().add(keyImportWidget);

                 bindjQuery();
         }

         public native void bindjQuery() /*-{
             alert(Inside GWT bindjQuery);
                 $wnd.bindjQuery();
         }-*/;

 }

 So, this works... The problem is... I don't like it. :-) Is this the
 recommended way of importing things like that? I am uncomfortable with
 this as I have no clue what else JQuery might be doing in its other
 functions... For all I know, it uses its onLoad function somewhere
 else as well and it never gets called. So, just because this worked
 for whatever I am doing, it doesn't seem like this is the cleanest
 approach.

 Can someone please give me some tips on this?

 Much appreciated!

 to resort to Java String.

 Now I could do the following, but I would have to re-write the toJson/
 fromJson methods for each implementation -  not acceptable to me!

 class PersonBase
 {
  String firstname;
  String lastname;
 }

 class Person_Client extends PersonBase
 {
public fromJSON (om.google.gwt.json.client.JSONObject x)
{
   // code to read from JSONObject and set firstName and lastName
}

public com.google.gwt.json.client.JSONObject toJson()
{
   // code to convert firstname + lastname to JSON
}
 }

 class Person_Server extends PersonBase
 {
public fromJSON (org.json.JSONObject x)
{
   // code to read from JSONObject and set firstName and lastName
}

public org.json.JSONObject toJson()
{
   // code to convert firstname + lastname to JSON
}
 }

 There must be an easier way!

Re: uibinder and nested layout

2010-11-09 Thread Prashant Hegde

In our application, we have a top level UiBinder which sets the layout, with
the content as a LayoutPanel which has a ui:field assigned to it. This
ui:field is used as a container for another ui:binder xml for the content..
(and the same thing can apply to other areas of the layout as well). We use
classic MVP which passes the container to the appropriate presenters when it
is time for display. The presenter sets the view to the container. So in
essence, there is no nesting, but a definition of the container, which is
set at a different place in the application.

Hello,

I have a requirement for an HTML page with a top horizontal header bar, a
large middle panel that will itself contain the left navigation column, a
middle content panel and a right side margin for showing Associated
content. At the bottom is a footer with its own content. To lay this out, I
want to use UiBinder. How do I nest UiBinder fields? In other words, how to
refer to @UiFields that are declared not in the main outer page class but in
classes that are @UiFields of the main page class? Is it even possible to
nest UI classes into one layout?

Thank you list!

Re: How to use JSONObject with common code shared between client and server

2010-11-09 Thread Kashif

No, I don't want to use Overlays - because that forces me to have a
DTO class that has separate implementation on client and server.

The whole point of using JSONObject is that I have a java API that I
can use to marshall/unmarshall DTO objects regardless if I'm sending
them from client to server or vice versa.

why is com.google.gwt.user.client.ui.Widget.addHandler(H, TypeH)
protected? in case I want to fire a custom event on a widget so that
the widget is not aware of custom event handler, it makes it difficult

[gwt-contrib] UiBinder. Using negative values in LayoutPane layer.

2010-11-09 Thread Konstantin.Scheglov

One of the users of GWT Designer found that code like this causes
rendering failure.

g:layer left=-34px width=109px top=70px height=20px
g:CheckBox text=New CheckBox/
/g:layer

  As you can see, left attribute contains negative value.
  In Java version such value is not problem for left, right, top
and bottom.

  As I can see, problem is in LengthAttributeParser which does not
recognize negative values.
  I'm not sure what to do - we could add minus support, but is this
correct ideologically? Negative _length_ is not valid, but negative
_position_ is fine.

Re: [gwt-contrib] UiBinder. Using negative values in LayoutPane layer.

2010-11-09 Thread Ray Ryan

We shouldn't get hung up on the fact that LengthAttributeParser is misnamed
(ScalarAttributeParser?). Negative support sounds like the right thing to
do. Element parsers that are concerned about negative values could do their
own check for that, although it could be tricky to do correctly.

Did you just volunteer?

I think the refactoring has a positive effect even if we didn't need to
add this method.
The current code was a hack IMHO. This refactoring makes it clear that
synthetic modules are subclass with different behaviors. Since all
changed references (all under junit) actually expect a synthetic module
instead of a plain module, now the contract is enforced by static
typing.

GWTTestCase is also excluded.

super.maybeStartProxy() will start the proxy filter if the '-proxyTo'
option is set. This is an easy way to reuse code.
I can also reuse the code by creating
  protected final void startProxy()
and call it conditionally in GWTTestCase and always call it here. Does
this sound better?

I'm not sure about it -- E2E tests run for the whole application, so (to
my limited experience) there's only one module which contains entry
point.
OTOH, I'm experimenting with initializing Module Under Test in test
methods, so this will be addressed in next pass.

2010-11-09 Thread amitmanjhi


Reviewers: jat,

Description:
This patch makes three changes:
1. Excludes the client-side validation from being analyzed by api
checker. Will
remove this unnecessary exclusion once
http://code.google.com/p/google-web-toolkit/issues/detail?id=5566 is
resolved.
Currently, because of this bug there is a lot of console spew from
typeOracle
unable to find sources.

2. Removes the unnecessary entry from the white-list. The entry is
removed
because even prior to the addition of HTML(SafeHtml ..) call to the HTML
class
in 2.1, the class had two constructors, so a call like new HTML(null)
wouldn't
have compiled before. There is no API breakage because of this new
constructor.

3. Adds a unit test to exercise the case above.

I think this came up in the past as well. My vote is still for listing them
explicitly since the impl thing is a GWT convention, and ideally, we should
try to avoid api breakages in any public api even if it is in the impl
package. However, if someone does want to exclude particular impl packages,
adding an entry is easy.

2010-11-09 Thread Konstantin.Scheglov


 We shouldn't get hung up on the fact that LengthAttributeParser is misnamed
 (ScalarAttributeParser?). Negative support sounds like the right thing to
 do. Element parsers that are concerned about negative values could do their
 own check for that, although it could be tricky to do correctly.

 Did you just volunteer?

  Yes, this looks as easy change.

   As you can see, left attribute contains negative value.
   In Java version such value is not problem for left, right, top

   As I can see, problem is in LengthAttributeParser which does not

   I'm not sure what to do - we could add minus support, but is this
  correct ideologically? Negative _length_ is not valid, but negative

[gwt-contrib] Re: Public: GWT version of the JSR 303 Bean Validation TCK (issue1085801)

2010-11-09 Thread rchandia


This probably needs a README file to help users run the tests.

I was not able to generate a gwt-x.y.z.zip containing the validationtck
sample is that intended?


http://gwt-code-reviews.appspot.com/1085801/diff/3001/4001
File samples/build.xml (right):

http://gwt-code-reviews.appspot.com/1085801/diff/3001/4001#newcode46
samples/build.xml:46: gwt.ant dir=validation /
This should be gwt.ant dir=validationtck / if we want the
ValidationTck sample to appear in the generated gwt-x.y.z.zip
distribution.

But with that the ant build fails because there is no war folder under
samples/validationtck.

http://gwt-code-reviews.appspot.com/1085801/diff/3001/4002
File samples/common.ant.xml (right):

Do we really need to disable Checkstyle from all samples? Checkstyle is
supposed to be able to deal with super source.
