Re: GWT and Web Cam
May bad. I should have quoted to Christopher. Sorry. Webrtc it's nice, but, what we do with the down fall back on other browsers. 2012/12/7 Alberto Mancini ab.manc...@gmail.com Thanks, actually I do not want a dependency on flash but in case your project will be our first test :) My target, in the post I cited ,was doing 'capture' in javascript only so the real interest was on WebRTC, but I suppose Christopher will certainly like the project. Looking at the code adding webrtc support to the lib may be not so terrible just in case one want to use 'native' support when available and flash as a fallback, don't know if may be useful.

Best regards 2012/12/7 Alberto Mancini ab.manc...@gmail.com Hi Christopher, accessing the webcam is something the browser may be unable to do: recent browsers (just chrome afaik) that implement WebRTC's getUserMedia (http://www.webrtc.org/) may provide access to the stream coming from the webcam, else you're forced to use a plugin, for instance flash. If you want to use WebRTC, moving to GWT 2.5 and Elemental is in my opinion a good choice. If you want, you can find some info here http://jooink.blogspot.it/2012/11/gwt-augmented-reality-howto-step-2.html (just the first few lines, up to the copy into a canvas, then canvas's toDataURL() will give you the snapshot).

Re: Activities and places with MVP approach question
Hi Joseph i am not trying to move the backend things on AP i meant the actions of the user. Some user could bookmark the place of edit, create or read Products, for example. The place and activity per action. /#Addproduct: /#Editproduct:1312 /#Readproduct: or just one place different activities. /#Product:Read /#Product:New /#Product:Edit-1312 2012/11/26 Jesse Hutton jesse.hut...@gmail.com I have previously used one activity for C and U, and another for R (and D). It basically came down to the fact that the views were mostly the same between those pairs, so they could be reused and the activity (and presenter) could figure out the details and which controls to show based the action information the place (which you can get away with having one of). In addition, I also had a list activity for a total of 3 activities for each entity type.

Re: SuperDevMode not so super

Now, I'm a bit disappointed about the coolest new feature of 2.5 and I wonder if I have missed something. - Compilation is slow. It takes between 1 and 2 minutes plus the bootstrap time of my server app. The app has sth above 20k LOC and heavily uses RequestFactory and GIN code generators, maybe that's the reason? So overall startup performance is worse than with standard DevMode. - Code changes require a recompile. In DevMode non-structural changes are applied automatically by the Eclipse Debugger. - Debugging the code in the Browser is ... hm, it works. But honestly, nothing compare to a IDE debugger. Browsing through the source tree in Chrome is a pain with thousands of classes. - GWT CodeServer is very resource intensive. During compilation, I cannot use my machine for anything else. If it's running it takes more than 1GB of RAM.

GWT JSR 303 and setConstraintViolations() wrong Path name bug ?
Hello there today i am almost finish with a medium complex EntityProxy
editor module.
But now seems that i found a new hole or don't know why this happens.
This the proxy scenario:
in ProductoProxy i have:
@Valid
public ImpuestoProxy getImpuesto();
@Valid
public ImpuestoProxy getIeps();
whose are @Embedded pojos.
Then on the ImpuestoProxy i have properties that need be validated
differently when it is Impuesto or Ieps so i created a ImpuestoGroup and
ImpuestoIepsTasaGroup marker interfaces to validate differently using the
same Editor (see below why):
@NotNull(message=notNull, groups = {ImpuestoGroup.class,
ImpuestoIepsTasaGroup.class}) /*so be validated when it;s Impuesto or Ieps
*/
@DecimalMin(value=0.0, message=decimalMin:0.0, groups =
{ImpuestoGroup.class, ImpuestoIepsMontoGroup.class})
public Double getTasaImpuesto();
@NotNull(message=notNull, groups = {ImpuestoIepsMontoGroup.class}) /*
so be validated when it's type is Impuesto only */
@DecimalMin(value=0.0, message=decimalMin:0.0, groups =
{ImpuestoIepsMontoGroup.class})
public BigDecimal getMontoImpuesto();
...
Plus i need let user choose predefined valueproxy so i used a:
public class UiOptionalValueListBoxImplT, E extends EditorT extends
UiBaseBox implements IsEditorOptionalFieldEditorT, E{
...
}
So when the user edits a getImpuesto() and then want to save it i check for
constraints in this manner:
driver.flush();
ImpuestoProxy proxy = productoProxy.getIeps();
/* Here i cannot validate the whole ProductoProxy because some
constraints fails due my custom groups.
* so i need validate only the @Embedded proxy
*/
Set constraints = AddProductViewImpl.this.validator.validate(proxy,
proxy.getTipoIeps().equals(TipoIeps.MONTO) ? ImpuestoIepsMontoGroup.class :
ImpuestoIepsTasaGroup.class);
if(!constraints.isEmpty()){
driver.setConstraintViolations(constraints);
}
logger.log(Level.INFO, After the flush we got
+driver.getErrors().size());
In my Editor of ImpuestoProxy view i have my own validation ui framework
(user ui messages, etc ...) and to identify a property who us failing i use
their path then i compare with the path reported by ListEditorError
reported by the main driver.
The problem becomes here. The next behavior happens:
IsEditorValueBoxEditorT report path ok
foo.bar.client.view.Products.ImpuestoEditorImpl INFO: On the sub view we
got: ieps.unidadImpuesto notNull
but IsEditorTakesValueEditorT and IsEditorLeafValueEditorT don't
foo.bar.client.view.Products.ImpuestoEditorImpl INFO: On the sub view we
got: iepstipoIeps notNull
foo.bar.client.view.Products.ImpuestoEditorImpl INFO: On the sub view we
got: iepsnombreImpuesto notNull
As you can see there is missing . on the path name. ( iepsnombreImpuesto
should be ieps.nombreImpuesto )
Plase note if i validate the whole ProductoProxy the paths are reported
fine
Don't know it the conversion from
driver.setConstraintViolations(constraints); to ListEditorError fails or
it's the validation who reports badly the path. Will try atm.
Please help me.
Thanks.

Re: GWT JSR 303 and setConstraintViolations() wrong Path name bug ?
I just confirm that seems to be a bug ? on the conversion of
driver.setConstraintViolations(constraints) to ListEditorError in the
Editor framework
the jsr 303 reports like this:
Mon Nov 12 21:29:55 GMT-600 2012 foo.bar.client.view.BaseViewImpl INFO:
tipoIeps
Mon Nov 12 21:29:55 GMT-600 2012 foo.bar.client.view.BaseViewImpl INFO:
unidadImpuesto
Just to complement the information i have my subeditors in this manner in
my Top editor :
public class AddProductViewImpl extends BaseViewImpl implements
AddProductView, EditorProductoProxy{
@UiField(provided=true)
UiOptionalValueListBoxImplImpuestoProxy,ImpuestoEditorImpl impuesto = new
UiOptionalValueListBoxImplImpuestoProxy,ImpuestoEditorImpl(new
RendererImpuestoProxy() {
@Override
public String render(ImpuestoProxy object) {
return object != null ? (object.getNombreImpuesto() != null ?
object.getNombreImpuesto() : n/d) : Seleccione un impuesto;
}
@Override
public void render(ImpuestoProxy object, Appendable appendable) throws
IOException {
render(object);
}
}, new ImpuestoEditorImpl(true));
...
}
public class UiOptionalValueListBoxImplT, E extends EditorT extends
UiBaseBox implements IsEditorOptionalFieldEditorT, E {
...
}
Thank you.

Re: DoubleBox and Editor framework bug?
Seems that edioto framework is trying to get the Double.doubleValue()
without check if the object is null.
Any one ?
2012/11/11 Daniel Mauricio Patino León ceo.lion@gmail.com
Its normal when i use a DoubleBox in a Editor to edit a double property
(RequestFactoryEditorDriver)
if i clear the value of the box i get a null pointer exception?
If so how can i validate a DoubleBox with the JSR 303 Validation?
My code looks something like this:
@DecimalMin(value=0.0, message=decimalMin:0.0, groups =
{ImpuestoGroup.class, ImpuestoIepsGroup.class})
public double getTasaImpuesto();
g:DoubleBox ui:field=tasaImpuesto/g:DoubleBox
@UiField DoubleBox tasaImpuesto;
When i call the driver.flush() need to check the constraints i have this
results:
if i put a value diferent than number i get the on the ListEditorError
the bad value
if i put a lower than 0.0 value i can set the constraints to the
EditorDriver with driver.setConstraintViolations(constraints);
When i leave blank the field i expect a ListEditorError with a bad value
or the constraint but not a null pointer exception.
The line i get my atention is this one:
Caused by: com.google.gwt.core.client.JavaScriptException: (TypeError) :
Cannot read property 'value_0' of null
at Unknown.$doubleValue(
http://localhost:9876/proj/C6E66C9FC3DCB1FC08DFFFC07FE049E0.cache.js@21:38447
)
Seems that DoubleBox cannot handle the null value.
Please help me. Thank you.

Re: DoubleBox and Editor framework bug?
Hello Thomas, thank you for your answer. I understand how the ValueBox with their Render and Parser works. And i understand the difference using Double and double, so a work arround would be use Double wrapper instead primitive types? I think would be nice if the editor generate some code to handle this case and report like when the user use some bad input and then this can be reported in to the getErrors() so the NPE wont be raised. Like when you use bad values (1a) Bad value(1a) (empty) bad value(null) I will put a issue. 2012/11/11 Thomas Broyer t.bro...@gmail.com On Sunday, November 11, 2012 7:47:11 PM UTC+1, Daniel Mauricio Patino León wrote: Seems that edioto framework is trying to get the Double.doubleValue() without check if the object is null. Any one ? DoubleBox uses DoubleParser. DoubleParser returns 'null' if the value is the empty string, and otherwise uses a NumberFormat, and throws a ParserException if it cannot parse. Your edited object's property is of type 'double', not 'java.lang.Double', so when the field is empty, getValue() returns 'null', and the Editor framework tries to unbox the 'null' to put it into your 'double' property, hence the NullPointerException. With any illegal value, DoubleParser throws; in that case, the ValueBoxEditor returns the last known value, which explains why it doesn't throw in that case. I think you can file an issue, but I wonder what the fix should be (if any): what value should be put into your property when the field is empty (i.e. the value is 'null')? or should the Editor framework generate specific code for primitive values to handle nulls and report errors without trying to change the value (to avoid NPEs)? -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

DoubleBox and Editor framework bug?
Its normal when i use a DoubleBox in a Editor to edit a double property
(RequestFactoryEditorDriver)
if i clear the value of the box i get a null pointer exception?
If so how can i validate a DoubleBox with the JSR 303 Validation?
My code looks something like this:
@DecimalMin(value=0.0, message=decimalMin:0.0, groups =
{ImpuestoGroup.class, ImpuestoIepsGroup.class})
public double getTasaImpuesto();
g:DoubleBox ui:field=tasaImpuesto/g:DoubleBox
@UiField DoubleBox tasaImpuesto;
When i call the driver.flush() need to check the constraints i have this
results:
if i put a value diferent than number i get the on the ListEditorError
the bad value
if i put a lower than 0.0 value i can set the constraints to the
EditorDriver with driver.setConstraintViolations(constraints);
When i leave blank the field i expect a ListEditorError with a bad value
or the constraint but not a null pointer exception.
The line i get my atention is this one:
Caused by: com.google.gwt.core.client.JavaScriptException: (TypeError) :
Cannot read property 'value_0' of null
at
Unknown.$doubleValue(http://localhost:9876/proj/C6E66C9FC3DCB1FC08DFFFC07FE049E0.cache.js@21:38447)
Seems that DoubleBox cannot handle the null value.
Please help me. Thank you.

GWT 2.5 Validation problem
I want to validate a child Proxy (@Embeddable) on an EntityProxy with the
new Validation frame work but i have a problem
The code looks some thing like this:
@ProxyFor(locator=BaseEntityLocator.class, value=Producto.class)
public interface ProductoProxy extends EntityProxy {
public void setInformacionAduanera(InformacionAduaneraProxy
informacionAduanera);
@Valid
public InformacionAduaneraProxy getInformacionAduanera();
...
}
@ProxyFor(value=InformacionAduanera.class)
public interface InformacionAduaneraProxy extends ValueProxy {
@NotNull(message=notNull)
public Date getFecha();
}
On other part of the App
this.productoProxy = request.create(ProductoProxy.class);
informacionAduaneraProxy = request.create(InformacionAduaneraProxy.class);
this.productoProxy.setInformacionAduanera(informacionAduaneraProxy);
Then finally
RequestContext r = driver.flush();
Set contraints =
Validation.buildDefaultValidatorFactory().getValidator().validate(productoProxy);
I expect the @Valid annotation on the Entity proxy cascade the @NotNull on
my InformacionAduaneraProxy but it dosn't
happen.
The validator only returns the constraints for the EntityProxy
I have both classes on the :
@GwtValidation(value={ CredencialesUsuario.class, ProductoProxy.class,
InformacionAduaneraProxy.class })
Why?
Thank you.

Elemental missing getWindow().newFormData()
Iam trying to implement a html5 file api + xmlhttrequest level 2 upload on
my project.
But sems that Elemental is missing things of FormData and i can't send
over XMLHttpRequest object.
How to construct a object of FormData ?
FormData formData = /*getWindow().newFormData() - doesn't exist */null;
from http://dvcs.w3.org/hg/xhr/raw-file/tip/Overview.html#interface-formdata
interface FormData {
void append
http://dvcs.w3.org/hg/xhr/raw-file/tip/Overview.html#dom-formdata-append(DOMString
name, Blob http://dev.w3.org/2006/webapi/FileAPI/#blob value, optional
DOMString filename);
void append
http://dvcs.w3.org/hg/xhr/raw-file/tip/Overview.html#dom-formdata-append(DOMString
name, DOMString value);
};
in the elemental one just
formData.append(name, value, filename)
Where all parameters are strings.

GWT 2.5 RC2 EntityProxy Validation
Hello there.
I have a question of wich is the best option to validate my domain objects
on the client side with RequestFactory.
It's posible to validate a Proxy with the new Validation of 2.5 RC2 ?
If i do a validation of my proxy don't get any constraints violations.
What i did to get a work arround of this was move the anoations to my proxy:
@ProxyFor(value=Employee.class, locator=EntityLocator.class)
public interface EmployeeProxy extends EntityProxy {
@NotNull(message=Cannot be empty.)
@Size(min = 4, message = Name must be at least 4 characters long.)
public String getFirstName();
/* .. */
}
Then i implemented that interface on my domain object.
@Entity
public class Employee extends EntityBase implements EmployeeProxy {
@Column(nullable = false)
private String firstName;
@Override
public String getFirstName() {
return firstName;
}
/* .. */
@Override
public EntityProxyId? stableId() {
return null;
}
}
Now i get validation on the client side with:
EmployeeRequest request = requestFactory.employeeRequest();
EmployeeProxy employeeProxy = request.create(EmployeeProxy.class);
request.addNewEmployee(employeeProxy);
driver.edit(employeeProxy, request);
SetConstraintViolationEmployeeProxy violations =
validator.validate(employeeProxy);
System.out.println(violations);
and also on the server side when i click on save button with this:
driver.flush().fire(new ReceiverVoid() {
@Override
public void onSuccess(Void response) {
Window.alert(Succeed);
}
@Override
public void onConstraintViolation(SetConstraintViolation? violations) {
//ConstraintViolation? violation = violations.iterator().next();
//Window.alert(violation.getMessage() +
+violation.getPropertyPath().toString());
for(ConstraintViolation? violation: violations){
if(violation.getPropertyPath().toString().equals(age)){
ageError.setText(violation.getMessage());
}else if(violation.getPropertyPath().toString().equals(firstName)){
firstNameError.setText(violation.getMessage());
}else if(violation.getPropertyPath().toString().equals(lastName)){
lastNameError.setText(violation.getMessage());
}
}
// ... others
}
});
I this correct?
This can cause problems ?
thank you.

RequestFactory and Editor Frame Work Question
Hello there RequestFactory and EditorFramework gurus and all the comunity.
I have the following structure
public class CitaWidget{
//here i load a complex graph with request factory
// in some place of this class i create a Editor of each proxy on a list
for(UnidadProxy unidadProxy: response.getUnidades()){
// i create editors here ...
final UnidadCitaEditor unidadCitaEditor = new
UnidadCitaEditor(unidadProxy);
//
}
}
public class UnidadCitaEditor implements EditorUnidadProxy{
// this class is a editor for the UnidadProxy obtained by the previous class
// here each UnidadProxy has many CitaProxy so i created a ListEditor
@UiField(provided=true) CitaListEditor citas;
protected DefaultRequestFactory factory = DefaultRequestFactory.instance;
protected interface Driver extends RequestFactoryEditorDriverUnidadProxy,
UnidadCitaEditor{}
protected Driver driver = GWT.create(Driver.class);
public UnidadCitaEditor (){
driver.initialize(this);
factory.initialize(new SimpleEventBus());
// then i create the top driver and the request context
final UnidadRequest unidadRequest = factory.unidadRequest();
unidadRequest.citaUnidadChange(unidadProxy).with(citas,citas.alumno,citas.doctor,citas.responsable).to(new
ReceiverUnidadProxy() {
@Override
public void onSuccess(UnidadProxy response) {
UnidadRequest unidadRequest = factory.unidadRequest();
unidadRequest.citaUnidadChange(response).with(driver.getPaths()).to(this);
// iam trying to reuse the editor with a new RequestContext, for better
ui experience for the final user
driver.edit(response, unidadRequest);
}
});
driver.edit(unidadProxy, unidadRequest);
}
}
public class CitaListEditor extends FlexTable implements
IsEditorListEditorCitaProxy, CitaEditor,
HasRequestContextListCitaProxy{
protected class CitaEditorSource extends EditorSourceCitaEditor{
// business logic for the cita editor source
}
private void onNewProxy(){
final CitaProxy citaProxy = ctx.create(CitaProxy.class);
// the cita proxy is atached to the list
// the the CitaEditor can handle the binding ...
// on save of the CitaEditor i fire the main RequestContext that one on
the UnidadCitaEditor to persist the data
}
}
Well as you friends can see i have a widget that retrive a list of Unidades
then each unidad has a List of Citas then i create a editor for each Unidad.
Then the user call the onNewProxy() the new cita proxy its atached to the
list correctly.
The thing here is i want when a user creted a new CitaProxy and when the
editor of this Cita hides () call save fire the requestcontext
This because iam using a extensive UI layout (FlexTable DND some visual
validation, etc..) to represent the Cita's proxys.
I want to maintain the Client side ui but save the CitaProxy on the server.
I know the RequestFactory is per request only, so i have a problem here.
I tryed to getback the same Unidad proxy and then reatach to the driver as
the follow lines of the class UnidadCitaEditor :
unidadRequest.citaUnidadChange(unidadProxy).with(citas,citas.alumno,citas.doctor,citas.responsable).to(new
ReceiverUnidadProxy() {
@Override
public void onSuccess(UnidadProxy response) {
UnidadRequest unidadRequest = factory.unidadRequest();
unidadRequest.citaUnidadChange(response).with(driver.getPaths()).to(this);
driver.edit(response, unidadRequest);
}
});
Iam trying to reuse the editor and create a new RequestContext to be fired
when a new CitaProxy is added to the list of the ListEditor
so my ListEditor CitaListEditor can maitain the UI and add the new ones
only.
The problem is that iam getting an exception here...

Use RequestFactoryProxy on UiBinder Template.
Should be great if we can use a proxy on a UiBinder template with

public VerPresupuestos(final PacienteProxy pacienteProxy) {

Re: Use RequestFactoryProxy on UiBinder Template.
Yhea! this rocks!
I missed the @UiField(provided=true)
Nice, its better to do at this way than change in code.
Thank you thomas.
2012/7/19 Thomas Broyer t.bro...@gmail.com
I don't see the @UiField(provided=true) on the pacienteProxy field on your
code.

Re: Simple GWT Dual list
Thank you for your sharing. 2012/7/10 Alain Ekambi jazzmatad...@gmail.com Nice job Juan. Works great. Maybe you should also think and Drag and Drop ? Cheers, Alain 2012/7/10 Juan Pablo Gardella gardellajuanpa...@gmail.com Hi Thanks for the suggestions. I will include this features soon. Juan 2012/7/9 Ian Mayo i...@planetmayo.com Hi there, nice clean implementation - well done. A couple of minor suggestions, if you don't mind ;-) There's a UI precedent in controls like this whereby double-clicking on an item moves it to the other list. This lets the user to continue to focus their gaze on the list in question. The second, more minor suggestion is that it's also quite common to have move all buttons ( ) that move the whole list from one side to the other - though I believe this has more infrequent value. -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: changing an entity proxy within request in GWT editor framework
In this scenario i think you are using a ListEditor
What i do is this:
From your editor when you create your new EntityProxy pass it to the
ListEditor of Bar implementing TakesValueV
then when you create a new EntityProxy of Bar set it as if you are working
on the server side with bar.setFoo(foo);
The RF on the server side will populate the relationship for you.
That's all a client only side approach for this scenario.
2012/6/26 Human izatara izat...@gmail.com
I try to build an application based on spring-roo generated GWT code. now
I want to do this scenario.
class Foo{
ListBar barList;
}
class Bar{
Foo foo;
}
and barList is owned entity collection for Foo, that means Bars will be
saved in Foo crud scenario. but foo link in Bar is not set automatically
and I got a constraint violation.
I want to find best place for setting foo link in each newly created Bar.
where can I create such link in an application with spring roo gwt
application architecture like or generally in an mvp gwt application which
used editor framework and request factory?

Re: How to wire multiple editor to same bean.
Use a main view
PatientRegistrationFormEditor implements EditorBeanProxy{
}
then use separated views
PersonalDetailsView implements EditorBeanProxy /*
ValueAwareEditorBeanProxy if you need the proxy for some reason*/{
}
Then anonate you partial views on your main view with
@Path() /* this make the subeditor (partial view) edit the same beanproxy
*/
@UiField PersonalDetailsView personalDetailsView;
Done.
El 18 de abril de 2012 10:49, saurabh saurabh saurabh.bl...@gmail.comescribió:
Hi all,
I don't have much experience with Editor frameworks so this question
may appear naive or dumb.
So suppose we have a big bean or proxy having a many fields. A good
idea in view part could be having group them under TabLayoutPanel
otherwise a big form on a page may not appear user friendly.
Example:
Patient Registration Form
---
||Personal Details || Patient Habbits || Family History || Medical
History || Insurance || |
---
|
|
|
|
|
---
Here I feel comfortable to have five different UI like detailsView,
habbitsView and so on and having them under one composite but all of
'em are concerned to one Class Patient.
So my question is how I can wire multiple Editors to same bean, each
for different set of properties.
I don't find much on net for Editors, I guess it could be
CompositeEditors, but I need some help for how to do it.
Thanks in advance

ListEditor question.
Hello Every one.
I have a problem with ListEditor. The case is this:
I have a main editor for AProxy then AProxy has a list of BProxy 's
so in the main view i have this:
@UiField RespositorioUsuario archivos;
Then i have a sub view with something like this:
public class RespositorioUsuario extends Composite implements
IsEditorListEditorArchivoProxy, RepositoryItem ,
HasRequestContextListArchivoProxy {
// i manage a list of RepositoryItem editors
private class RepositorioEditorSource extends
EditorSourceRepositoryItem {
@Override
public RepositoryItem create(int index) {
RepositoryItem item = new RepositoryItem();
container.insert(item, index);
return item;
}
@Override
public void dispose(RepositoryItem subEditor) {
subEditor.removeFromParent();
}
@Override
public void setIndex(RepositoryItem subEditor, int index) {
container.insert(subEditor, index);
}
}
private ListEditorArchivoProxy, RepositoryItem subeditors =
ListEditor.of(new RepositorioEditorSource());
@Override
public ListEditorArchivoProxy, RepositoryItem asEditor() {
return subeditors;
}
private AlumnoRequest request;
@Override
public void setRequestContext(RequestContext ctx) {
request = (AlumnoRequest) ctx;
}
}
Then the BProxy editor is RepositoryItem
public class RepositoryItem extends Composite implements
EditorArchivoProxy {
// iam the editor of BProxy
}
So finally i want to add one Item the the list with something like this:
ArchivoProxy a = request.create(ArchivoProxy.class);
subeditors.getList().add(a);
But i cant, and dont know why... i got a NullPointerException.

Re: ListEditor question.
My bad.
Of course i need to initialize the ArrayList on the main Proxy when create
a new one. So proxy.setArchivos(new ArrayListArchivoProxy());
solved this issue.

Re: Client/Server communication. GWT-RPC ? GIlead ? Dozer ? RequestFactory ?
RF awkward ? I dont think so, finally the rpc aproach with dto's and other stuff are sent to the client side in some like JSON (GWT Serialization), RequestFactory uses JSON to pass from server to the client and it just works well. In my opinion (i did two projects with the DTO thing) the RequestFactory its the best way to build Enterprise Applications with JPA (Hibernate). I recommend to you read careful the documentation about the RF. Just my opinion. El 7 de abril de 2012 17:20, Jeff Schnitzer j...@infohazard.org escribió: Just to clarify: Objectify isn't a serialization framework. It's a persistence API - Hibernate for the GAE datastore makes me cringe but it gives you the right idea. Using Objectify you still have to decide whether to use your entity domain objects or DTOs for the GWT-RPC boundaries. I tend to use DTOs, although I'll use the entity objects themselves if they are simple enough. They usually aren't. Jeff (creator of Objectify) On Sat, Apr 7, 2012 at 1:09 PM, Joseph Lust lifeofl...@gmail.com wrote: fabio, While mechanisms like Objectify exist to pass the same entity to the UI from Hibernate, I have found that DTO objects are still the most robust solution. Obviously you don't want to send the secret Hibernate goodness to the UI, you don't want LazyLoading exceptions, and chances are the entity has way more information than you need in the UI. Since we often have to move a lot of information to the UI (i.e. 10K plus records) it makes sense to use the Entity in the DAO layer and pack up the data into the DTO's in the service layer in an efficient manner. Keep in mind too that if you pass your entity bean to the UI, you're telling prying eyes a lot about your DB design. Also, we usually use a DtoContainer object for many pages. For example, if WidgetX needs 10 fooDTO's and 3 barDTO's, then you pack them up in a WidgetXContainer. This is especially useful because if you decide later that WidgetX needs 4 wombatDTO's, you whole RPC setup from interfaces, to services, to async handlers don't need to be touched. You just add another property to the container and then just put in and take out the new object. Others might push for a framework like Objectify, but my experience with such frameworks is that you lose in the long term if you plan to do anything beyond the purview of their limited use cases.

Re: DataGrid right click
Hey Sachin thank you.
Do you know if this property has cross browser support?
2012/3/6 Sachin Shekhar R sachin@gmail.com
In the application html file ensure you have set up body tag like - body
*oncontextmenu=return false;*
This suppresses the *default *browser context menu.

Re: DataGrid right click
event.preventDefault();
event.stopPropagation();
Why these lines doesnt work?
In DataGrid you can overdrive the onBrowserEvent2(){} but it is fired after
the onBrowserEvent(){}
and i think is why my code doesnt work.
Is there another w3c validation pass way to do this?
Thank you.

Re: ValueListBox in GWT editor with one-to-one relationship creating a new entry in related table
I have some kind of problem lke yours.
I am creating a new Proxy:
LayoutExampleRequest r = requestFactory.employeeRequest();
DepartmentProxy d = r.create(DepartmentProxy.class);
r.save(d);
departmentEditor.editProxy(d, r);
Then pass the Proxy and the Request(LayoutExampleRequest ) to my editor
driver.edit(proxy, request);
Ultil here ! everything works as espected. Now iam getting with a suggest
box Proxys of EmployeeProxy.
search = new SuggestBox(new SuggestOracle() {
@Override
public void requestSuggestions(final Request request,final Callback
callback) {
System.out.println(request.getQuery());
//ignore less than 3
if(request.getQuery().length() 3){
requestFactory.employeeRequest().search(request.getQuery()).fire(new
ReceiverListEmployeeProxy(){
@Override
public void onSuccess(ListEmployeeProxy response) {
ListMySuggestionEmployeeProxy suggestions = new
ArrayListMySuggestionEmployeeProxy();
for(EmployeeProxy e:response){
MySuggestionEmployeeProxy suggestion = new MySuggestionEmployeeProxy();
suggestion.setModel(e,e.getFirstName(),e.getFirstName()+
+e.getLastName());
suggestions.add(suggestion);
}
callback.onSuggestionsReady(request, new Response(suggestions));
}
});
}
}
});
MySuggestion is a wrapper class to handle the EmployeeProxy.
Now i want to add this EmployeeProxy to my DeparmentProxy since i have a
@OneToOne on JPA.
search.addSelectionHandler(new SelectionHandlerSuggestOracle.Suggestion()
{
@Override
public void onSelection(SelectionEventSuggestion event) {
MySuggestionEmployeeProxy s =
(MySuggestionEmployeeProxy)event.getSelectedItem();
proxy.setSupervisor(s.getModel());
}
});
proxy is a EntityProxy for Deparment
then i fire the driver:
departmentEditor.getDriver().flush().fire(new ReceiverVoid() {
@Override
public void onSuccess(Void response) {
Window.alert(Success);
// refresh the datagrid
Range range = dataGrid.getVisibleRange();
dataGrid.setVisibleRangeAndClearData(range, true); //1st way
// create a new DepartmentProxy to bind to
the Editor.
createProxy();
// change button text
updateButton.setText(Save);
}
@Override
public void onConstraintViolation(SetConstraintViolation? violations) {
for(ConstraintViolation v :violations){
Window.alert(v.getMessage()+ +v.getPropertyPath());
}
}
@Override
public void onFailure(ServerFailure error) {
Window.alert(error.getMessage());
}
});
The problem is iam getting ConstraintViolations from the EmployeeProxy, is
like the driver atach the EmployeeProxy but with null values.
(Take a look iam validating my Entityes with *JSR*-*330* )
Dont know how to make a relationship with a new Proxy with other taked from
the server.
Any help would be nice!
Thank you
2012/2/25 Thomas Broyer t.bro...@gmail.com
Without seeing more code, I'd say it's your server-side code fault: when
sending the Address back to the server, you're not retrieving the entity
back from the database but creating a new one, *or* you don't attach the
entity correctly to your session when persisting, which then persists a
new row instead of updating an existing one.

Hi
I am using the sample code example for ListDataProvider column sorting
(http://code.google.com/webtoolkit/doc/latest/
DevGuideUiCellTable.html#columnSorting)
to sort on a column in my application. Debugging the application I
can see the column is being sorted after I click on column header but
the display is never refreshed in the view.
Things to note is I am using paging for displaying my data as the data
can be quite huge.
Thanks

Re: RequestFactoryEditorDriver example?
Buen ejemplo de GXT 3.0 y GWT 2.4. Sin duda usar GXT resuelve mucho de lo que con GWT tendrías que codear por ti mismo. Espero que la versión completa este lista pronto.

Re: save data to database with hibernate and rpc
I think the best way is use RequestFactory. Forguet DTO's or third party
librarys
2012/1/27 Sebastian Gurin sgu...@softpoint.org
I agree with you about gilead intrusiveness. Also I see the project is not
mantained any more. In my case I didn't get it to work, but google's
using_gwt_with_hibernate.html document refer to it as a sollution. That is
why I recommended it.
I will keep investigating Hibernate filter for future gwt+hibernate
projects. Thanks for the info.
Regards.

Hi I developed my web apps gwt and persist the model with hibernate.
You
have lot of articles about it
http://code.google.com/intl/es-ES/webtoolkit/articles/using_gwt_with_hibernate.html
my advice:
The main problem you will encounter is compatibility issues between
model
object managed by hibernate and gwt rpc java object serialization.
Hibernate poblate your bean classes using datatypes unsupported by gwt
rpc. Gwt rpc only understand common java type implementations ( like
HashMap, HashSet ) . In particular, in many-relationships, if you
configure
hibernate with lazy=false for automatically loading collection
properties, hibernate will use java.lang.Set implementation
unsupported by
gwt rpc serialization.
I recommend you tu use data transfer objects (DTO) object to wrap your
real model classes.
If you really wnt to use your existing java model directly with
hibernate
and gwt rpc, you have choices:
1) use a library like http://noon.gilead.free.fr/gilead/.
2) do not let hibernate manage collections:
- Use lazy=true in hiberate
- Make your DAO or BL classes API to provide with methods for
retrieving many-relations - like ListApple getApples(long treeId);
make
sure those methods return objects compatible with gwt rpc (like
LinkedList,
HashSet, etc)
good look

Ok! i created this:
@ProxyFor(SortConfig.class)
public interface SortConfigProxy extends ValueProxy {

public void setOrder(String order);

So my problem is how to create a instance of that proxy on the client side.
PersonRequest r = requestFactory.personRequest();
SortConfigProxy p = r.create(SortConfigProxy.class);

Re: How to transfer ColumnSortList info to the server side.
r.test(p).fire();
sorts.add(p);
test() method in my RequestContext
RequestSortConfigProxy test(SortConfigProxy sortConfigProxy);
call my DAO!
public SortConfig test(SortConfig config){
return new SortConfig(config.getColumn(), config.getOrder());
}
Then i can use the proxy to send it again to the server.
Can i only create a ValueProxy from the Server Side?
From the Getting Started
A proxy type will be available on the client if it is:
- Referenced from a RequestContext as a Request parameter or return type.

Re: GWT + CellTable + Paging with Hibernate
Any one can show me the direction of how to use Paging? Thank yopu
2012/1/23 Daniel Mauricio Patino León ceo.lion@gmail.com
Hello everyone.
I dont understan how paging works, and i cant get a SimplePaging get
work with my example.
I have a CellTable whit my own AsyncDataProvider:
public class PersonDataProvider extends
AsyncDataProviderPersonProxy {
private final PersonRequestFactory requestFactory;
public PersonDataProvider(PersonRequestFactory requestFactory) {
super(null);
this.requestFactory = requestFactory;
}
@Override
protected void onRangeChanged(final HasDataPersonProxy display) {
final Range range = display.getVisibleRange();
final int start = range.getStart();
/* not used insted use
display.getVisibleRange().getLength() as MAX
values*/
final int end = start + range.getLength();
requestFactory.personRequest().getAllPersons(start,display.getVisibleRange().getLength()).with(pet).fire(new
ReceiverListPersonProxy(){
@Override
public void onSuccess(ListPersonProxy response) {
/* what should i have here? */
updateRowData(start, response);
}
});
}
@Override
public void addDataDisplay(HasDataPersonProxy display) {
super.addDataDisplay(display);
// Request the count anytime a view is added.
requestFactory.personRequest().countPersons().fire(new
ReceiverLong(){
public void onSuccess(Long response) {
// the total count from server
updateRowCount(response.intValue(), true);
}
});
}
}
Then i got in my DataAccesObject:
public ListPerson getAllPersons(int start,int max){
Session session =
HibernateUtil.getSessionFactory().openSession();
Transaction tx = null;
try {
tx = session.beginTransaction();
System.out.println( limit +start+,5);
@SuppressWarnings(unchecked)
ListPerson persons =
session.createCriteria(Person.class).addOrder(Order.desc(myAge)).setFirstResult(start).setMaxResults(max).list();
System.out.println(List size +persons.size());
tx.commit();
return persons;
} catch (RuntimeException e) {
if (tx != null)
tx.rollback();
throw e;
} finally {
session.close();
}
}
But i cant it work the paging isn't show me the right berhaivor.
How can i use SimplePager with Hibernate on the server Side.
Thank you.

Validation on client side whit Editors
Im traying to use Validation.
my module xml has:
inherits name=org.hibernate.validator.HibernateValidator /
replace-with
class=mx.com.liondev.UIBinder.client.SampleValidatorFactory
when-type-is class=javax.validation.ValidatorFactory /
/replace-with
My SampleValidatorFactory Class:
public final class SampleValidatorFactory extends
AbstractGwtValidatorFactory {
@GwtValidation(value = Person.class, groups = {})
public interface GwtValidator extends Validator {
}
@Override
public AbstractGwtValidator createValidator() {
return GWT.create(GwtValidator.class);
}
}
My pojo:
public class Person implements Serializable{
private static final long serialVersionUID = -120449367149704989L;
@Size(min = 10)
private String firstName;
private String lastName;
etc...
}
And my Editor:
@UiHandler(myButton)
void handleClick(ClickEvent e){
Person p = myDriver.flush();
Validator validator =
Validation.buildDefaultValidatorFactory().getValidator();
@SuppressWarnings(unused)
SetConstraintViolationPerson violations =
validator.validate(p);
if(myDriver.hasErrors()){
Window.alert(myDriver.getErrors()+);
return;
}
Window.alert(Binding +p.getFirstName()+ +p.getLastName()+
has a
pet whit name +p.getMyPet().getName());
}
I should expect get violations if the @Size(min = 10) of the String
firstName is violated
but i cant get it work

Best way to prevent dual login in gwt.
Some one can give me a idea of how to manage this? i dont want let users log in in my GWT app (pure GWT dom manipulation) in two places at the same time, including the same browser (different tabs) any help be apreciated -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: Best way to prevent dual login in gwt.
We use our own security implementation (implement shiro or spring will delay our development), i just want a idea of how to implement this whit GWT only, no external fw, a simple way.

Re: Best way to prevent dual login in gwt.
I think Juan Pablo Gardella just give me a idead, I will check every Action of the user instead. i mean when the user open a new module or do some CRUD operation and yes the server side with help of the user table (db), and some kind of Callback wrapper. 2011/8/17 Juan Pablo Gardella gardellajuanpa...@gmail.com You must check every request with a filter, and in the case the request is not valid, show the log.

GWT Modules
Since i read the FAQ and features of GWT and i dindt see info about
this, can someone please tell me how the modules works?
I mean if i dev a Module Login whit a few clasess (Fast download just
a few kb's)
then i dev a Module A w/ arround 40 clasess (huge kb's)
then i dev a Module B w/ arround 40 clasess too
then i put a inherent to A and B on my Login Module xml file
the final ...XXX.cache.hmtl of my Login Module will load all
the code from the A and B Modules?
or it will load if i use them? when i say use, i mean create objects
from that Modules
ModuleAObject obj = new
or just for import a class from a Module A or B my app will load all
the js generated
Can i work here whit code spliting ? i mean:
GWT.runAsync(new RunAsyncCallback() {
public void onFailure(Throwable caught) {
Window.alert(Code download failed);
}
public void onSuccess() {
/* the code will be loaded async */
ModuleAObject obj = new ModuleAObject ();
}
});
Thank you. =)

Re: GWT Modules
Nice answer, Thank you Ryan.
I will do some refactor since i think its better dev into Modules than One
BIG Module
What do you think about Modules in GWT, you desing your apps in Modules?
2011/6/30 Ryan McFall mcfall.r...@gmail.com
I am pretty sure that part of the optimization the compiler does is to
only include code in the generated .js file that is actually in use.
Therefore, only implementations of the methods in modules A B that
are used by your Login module will be downloaded by the client.

Re: Problem with GWT Service results
RootPanel.get(mainContainer).add(new Label(Array lista 2:
+lista.toString()));
RootPanel.get().add(new Label(String.valueOf(Array lista 2:
+lista.size(;
for(int i = 0; i lista.size(); i++){
RootPanel.get().add(new Label(BOTON +i));
}
esto esta fuera del contexto de asíncrono
public void onSuccess(ArrayListString result) {
}
ese contrato del AsyncCallback es el que se ejecuta cuando el servidor
regresa el resultado
si ahi tu result esta vacio entonces checa el lado del servidor.
no debes tener problema con lista.addAll(result); // no addAll(0,x)
ya que esa lista se va a sobreescribir cada llamada al servidor
2011/6/21 Jose Luis Hernandez jose.hernande...@gmail.com
Hello!
I have a problem. I am calling to server side on GWT. The results of
call is an ArrayList (result). Inside onSuccess method another
ArrayList is wrapped with the result. However, if I want to use
ArrayList lista outside of onSuccess method it contains 0 elements,
but inside is like result ArrayList. How can I solve it? I have tried
to use lista as class attribute, static attribute,... but it doesn't
run.
Thanks!
public void addContainers() throws Exception {
final ArrayListString lista = new ArrayListString();
gwtService.obtainAttributesDevice(1, new
AsyncCallbackArrayListString(){
@Override
public void onFailure(Throwable caught) {
System.out.println(ERROR);
Window.alert(caught.getMessage());
}
@Override
public void onSuccess(ArrayListString result) {
RootPanel.get(mainContainer).add(new
Label(Array result:
+result.toString()));
RootPanel.get().add(new
Label(String.valueOf(Array result:
+result.size(;
lista.addAll(0, result);
RootPanel.get(mainContainer).add(new
Label(Array lista 1:
+lista.toString()));
RootPanel.get().add(new
Label(String.valueOf(Array lista 1:
+lista.size(;
}
});
RootPanel.get(mainContainer).add(new Label(Array lista 2:
+lista.toString()));
RootPanel.get().add(new Label(String.valueOf(Array lista 2:
+lista.size(;
for(int i = 0; i lista.size(); i++){
RootPanel.get().add(new Label(BOTON +i));
}
}
