Great work!!! 
One question, with new version of JsInterop, you have intension of migrate 
all library to JsInterop, and all UiBinder and Widget, to HTML pure 
template and native Elements?

Re: Large no of gwt modules

2016-01-31 Thread Cristian Rinaldi

Rajesh, 
  I implemented a large GWT application using turducken pattern, I do not 
think that GWT need something specific to dynamically load modules, 
remember that a GWT app is just a JS file, and can be externally charged by 
a component that is responsible for this, with the particular logic, 
according to your modular design and dependencies.
  You must have a cross event bus that can receive and send messages, then, 
every module, GWT or not, can translate addressing scheme, for example, 
Activities and Places in a GWT module.
  In each module, you can use code splitting, to increase efficiency.

I hope help with this.

Greetings..!!

Re: JsInterop - Collection of native Interfaces

   Most of the native code(JSNI), I used to object instantiation, now, in

   I changed a lot of the Promise.
   And I uploaded a test project called gwt-playground

Hello David:
  I am working on the same thing.
Some time ago, I went to GitHub project, 
 and now I have given support 
to the last update of annotations.
I think that all these projects have the end what will Elemental 2.0, but 
for now, are the projects that move us forward.
You can look some things to see if that's right.

Template Engine?

2015-10-07 Thread Cristian Rinaldi

Hello:

Were there any plans on working with templates (not UiBinder), templates 
related how angular or aurelia work.
I think it would be desirable to have such a project, because it is closer 
to how it works naturally with HTML today, too, I believe that using 
JsInterop would not be difficult to make the databinding using 
Object.observe

Thanks

JsInterop callback function with parameters

2015-09-24 Thread Cristian Rinaldi

Hey:
  
   I'm using JsInterop to map some JS APIs.
What is the best way to map a callback to receive multiple parameters?

For example, a jQuery click handler: function (event, params)

Java could be:
  Function (Event, Object []), but then is complicated to manipulate the 
"Object []", there is a more direct way?

about something similar,
Here the extract:

*"For single-abstract-method classes (SAM) without @JsType (or perhaps only 
the SAMs marked with Java8 @Functional), we are planning to do an auto 
conversion into real javascript function so that you can directly do this:"*

@Functional
public interface PromiseFn {
void f(Resolve resolve, Rejected rejected);
}

final Promise p3 = Browser.newPromise(new PromiseFn() { . . . }

@Functional need Java 8 support.

Hello Jens:

 I have just searched in GWT test and code, and talks of +Goktug Gokdogan

JsInterop advance?

2014-08-20 Thread Cristian Rinaldi

Community: 
 I'm playing with JsInterop , and I have two questions: 

 1) Are you planning to try the static methods of JS objects, such as 
Object, Promise, etc.? 
 2) How do when an instance is mapped to an existing Object, eg 
Promise, has a constructor with parameters? 
  
Currently to resolve this 1) I created the following class Factory: JS 


But the interfaces define a contract at the level instance of a class 
or object, this way of doing things, I do not know if it is semantically 
correct. 

   To solve 2) there are not many options: 

 Create a Factory that returns an instance of the object, because it 
has no meaning, only to make the new, implement the interface, because the 
compiler already does. 
 There is some progress in this? 

 I saw in one of the post a proposal to do something like this: 
 
 Promise Promise.Prototype p = new (new Function ., new Function 
);

Where Promise, is the interface defined with prototype = "Promise". 

@JsType(isNative = true, prototype = "Promise")
public interface Promise {
   
  void then(Function f);

  void cath(Function f);
  }

Here 'access to jsCore project:

I hope the answers ... 

greetings

Re: master/3.0.0 js interop ready to play with?

2014-08-13 Thread Cristian Rinaldi

The GWT maven plugin version 2.6.1 does not support JsInterop, so I made a 
fork of the project and gave support, default is "JS". 
If you want to change, set 

 NONE | JS | CLOSURE

Re: master/3.0.0 js interop ready to play with?

2014-08-11 Thread Cristian Rinaldi

I was playing with JsInterop and perform several examples 
   DataTables Plugin of JQuery (import) 
   Polymer (Path Observer, Object Observer), etc...

Here my exmaples:
   https://github.com/csrinaldi/samples-of-gwt/tree/master/gwt-playground

But I 2 question about JsInterop:

The first question with JsInterop is about the import methodology, when I 
define a interface that maps with a JS core Element, by example: Object or 
JSON, I not sure the best form for maps the static method of the Object, by 
example Object.observe(...), or JSON.stringify().

My understanding of JsInterop is that one defines an interface, which is 
implemented by the compiler. 
And the allocation for now is through a factory in JSNI, talking to 
correlate Object for example, for Polymer ObjectObserver:

public static native  ObjectObserver 
createObjectObserver(T obj)/*-{
 return new $wnd.ObjectObserver(obj);
}-*/;


But the asignations is a instance of Object, and the observe() method is a 
static method.

How to is the best form of map this case?

The second question is about function callback passed to the Javascript 
method

button.addEventListener("click", function(event){
console.log(event);
});

The way I found to the compiler to generate things correctly was:

button.addEventListener("click", EventListenerFactory.createEventListener(
new EventListener() {
 @Override
 public void onEvent(JsObject event) {
   //TODO
 }
}));

where:

public class EventListenerFactory {
public static native gwt_sample.EventListener createEventListener(
EventListener listener)/*-{
 return function(evt){
 listener.onEvent(evt);
 }
 }-*/;
}

and:

@JsType
public interface EventListener {
void onEvent(E event);
}

Thanks!!

Re: Can we use multiple mvp using single Entry point.

2014-08-07 Thread Cristian Rinaldi

This is not correct, commonDisplay is a container. 
The last mapper to resolve the activity will overwrite the container by 
inserting their view. 

If you want two areas, it is the fact of wanting to respond to the same 
state (place) with different behavioral alternatives (Presenter /View).

Re: JsInterop and EventListener

2014-07-23 Thread Cristian Rinaldi

I resolve this problem, 
If not an elegant solution, maybe the compiler should do it automatically, 
but the most instructed to answer this question is +RayCromwell
My solution was to make a small JSNI functions that return the object 
generated by JsType getting the same object as a parameter. 

Here's an example:

@JsType(prototype = "HTMLElement")
public interface HTMLElement extends Element {
  public void setAttribute(String align, String center);
  public void appendChild(HTMLElement element);
  public void addEventListener(String event, EventListener handler);

  @JsProperty
  public void setInnerHTML(String text);

  @JsProperty
  public void setInnerText(String text);
}

@JsType
public interface EventListener {
   void onEvent(E event);
}

public static native EventListener eventListener(EventListener handler) /*-{
 return function(evt){
 handler.onEvent(evt);
 }
}-*/;

@Override
public void onModuleLoad() {
  Document doc = getDocument();

  HTMLElement button = doc.createElement("button");
  HTMLBodyElement body = bodyElement();


  final Person person = new Person();
  PathObserver observer = PathObserverFactory.createObserver(person, "name"
);
  input.bind("value", observer);


  PathObserver observer1 = PathObserverFactory.createObserver(person, "name"
);
  observer1.open(eventListener(new OpenObserverListener() {
 @Override
 public void onOpen(String oldValue, String newValue) {
   window().getConsole().log(oldValue);
 }
   }));
   person.setName("Cristian");

   button.setInnerText("UPDATE - See the console");


   button.addEventListener("click", eventListener(new EventListener() {
  @Override
  public void onEvent(JsObject event) {
window().getConsole().log(person);
  }
   }));
   .
   body.appendChild(button);
 }

The all code in my Github:

JsInterop and EventListener

2014-07-23 Thread Cristian Rinaldi

I'm doing tests with JsInterop (JsType, JsExport, etc), and I encounter a 
problem when adding a listener. 

Part of my code:

@JsType(prototype = "HTMLElement")
public interface HTMLElement extends Element {
   public void setAttribute(String align, String center);
   public void appendChild(HTMLElement element);
   public void addEventListener(String event, EventListener handler);
   @JsProperty
   public void setInnerHTML(String text);
   @JsProperty
   public void setInnerText(String text);
}

HTMLElement button = doc.createElement("button");
HTMLBodyElement body = bodyElement();

button.setInnerText("UPDATE - See the console");

button.addEventListener("click", new EventListener() {
@Override
public void onEvent(JsObject event) {
window().getConsole().log(event);
}
});

The handler is never executed...

The code generated for copiler is:

_.onModuleLoad = function() {
  var body_0, button, div, input_0, observer, p, person;
  body_0 = $wnd.document;
  div = body_0.createElement("DIV");
  p = body_0.createElement("P");
  input_0 = body_0.createElement("input");
  button = body_0.createElement("button");
  body_0 = $wnd.document.body;
  person = new clgscm$Person;
  observer = new $wnd.PathObserver(person, "name");
  input_0.bind("value", observer);
  (new $wnd.PathObserver(person, "name")).open(new clgsc$gwt_sample$01(this
));
  person.name = "Cristian";
  person.name = "Cristiaa";
  button.innerText = "UPDATE - See the console";
*  button.addEventListener("click", new clgsc$gwt_sample$02(this));*
  $wnd.console.log("%cWelcome to JSInterop!%c", initValues(
jl$getClassLiteralForArray_0(cggl$Ljava_lang_String_2_classLit, 1),
 $intern_2, 2, 4, ["font-size:1.5em;color:#4558c9;", 
"color:#d61a7f;font-size:1em;"]));
  div.appendChild(p);
  div.appendChild(input_0);
  body_0.appendChild(div);
  body_0.appendChild(button);
};
.
.
createForClass(62, cggl$Ljava_lang_Object_2_classLit);
*function clgsc$gwt_sample$02(this$0) {*
*  this.this$01 = this$0;*
*  jl$$0init__V__devirtual$0(this);*
*}*

---


The generated code should be 

button.addEventListener("click", function(e){...});

I think so ... :)

Any Idea?
Thanks...

Re: GWT JS Interopt

2014-07-23 Thread Cristian Rinaldi

HTMLElement implementation is done by the GWT compiler, so the code you say 
I would not know how to incorporate it. 

For example, I am using Polymer PathObserver:

public interface OpenObserverListener {
  void onOpen(String oldValue, String newValue);
}




@JsType(prototype = "PathObserver")
public interface PathObserver {
  void open(OpenObserverListener handler);
}




PathObserver observer1 = PathObserverFactory.createObserver(person, "name");
observer1.open(new OpenObserverListener() {
  @Override
  public void onOpen(String oldValue, String newValue) {
window().getConsole().log(oldValue);
window().getConsole().log(newValue);

  }
});


And I have the same problem, 
sorry if I have not understood what you have told me. 

Any idea?

Thanks.

Re: GWT JS Interopt

2014-07-22 Thread Cristian Rinaldi

I have the same problem with addEventListener, the generated code is not 
exactly as you mention: 

This is my code:

public interface EventListener {
void onEvent(E event);
}

@JsType(prototype = "HTMLElement")
public interface HTMLElement extends Element {

public void setAttribute(String align, String center);

public void appendChild(HTMLElement element);

public void addEventListener(String event, EventListener handler);

@JsProperty
public void setInnerHTML(String text);

@JsProperty
public void setInnerText(String text);
}

.
HTMLElement button = doc.createElement("button");
.
.
button.setInnerText("UPDATE - See the console");

button.addEventListener("click", new EventListener() {
@Override
public void onEvent(JsObject event) {
window().getConsole().log(event);
}
});




body.appendChild(button);
.


This is the generated code:

 _.onModuleLoad = function() {
  var body_0, button, div, input_0, observer, p, person;
  body_0 = $wnd.document;
  div = body_0.createElement("DIV");
  p = body_0.createElement("P");
  input_0 = body_0.createElement("input");
  button = body_0.createElement("button");
  body_0 = $wnd.document.body;
  person = new clgscm$Person;
  observer = new $wnd.PathObserver(person, "name");
  input_0.bind("value", observer);
  person.name = "Cristian";
  button.innerText = "UPDATE - See the console";
*  button.addEventListener("click", new clgsc$gwt_sample$01(this));*
  $wnd.console.log("%cWelcome to JSInterop!%c", 
initValues(jl$getClassLiteralForArray_0(cggl$Ljava_lang_String_2_classLit, 
1), $intern_2, 2, 4, ["font-size:1.5em;color:#4558c9;", 
"color:#d61a7f;font-size:1em;"]));
  div.appendChild(p);
  div.appendChild(input_0);
  body_0.appendChild(div);
  body_0.appendChild(button);
};

*function clgsc$gwt_sample$01(this$0) {*
*  this.this$01 = this$0;*

Any Suggestion?

Re: MVP with multiple EntryPoints

2012-11-12 Thread Cristian Rinaldi

Joseph, thanks a lot for your predisposition
Another question but no less important:

You are using injection of dependency in the projects, e.g: peaberry with 
Guice or Weld?

Greetings!!

Hi Joseph:

Thanks a lot, it was an interesting answer. Beyond GWT, I'm courious about 
how are you managing dinamyc ORM extensions, i.e. if you are using JPA, how 
are you merging domain classes from several OSGi bundles.

Best regards.

Re: Indexed DB support

2012-09-20 Thread Cristian Rinaldi

1) I am using IndexedDB with Elemental API, but is implemented the 
old specification of IndexedDB and I can't find the way to assign the 
version, therefore, the VersionChange is never launched.

2) Try updating WebCore with all IDL, but when running the build script,

Re: MVP with multiple EntryPoints

2012-09-12 Thread Cristian Rinaldi

Andrei, thanks for response.
In our architecture we have a MainModule that manages all aspects from 
Layout visualization, e.g. to request for maximization in the central 
region, or to request for display another region in the general layout. 
Also defines common places that are used by other modules, e.g. 
ConfigurePlace, FindGloblaPlace. In that case, the main module reacts by 
setting the layout.

This MainModule define some handlers to response a request from the other 
modules (entry points) over localization in the Layout.
Our MainModule registers all modules in the aplication, exists modules that 
are entry points and others that are inside distribution (same 
compilation). The MainModule in itself is an module.

Your proposed solution is ok, but, the fact of reload pages for each link 
of module, disables the posibility to manage external Layout from a 
MainModule.
We want to make each module to have their own stack of places, 
placehistorymapper, placecontroller and placehistoryhandler, event 
MainModule.

Re: MVP with multiple EntryPoints

Hi Thomas, thanks for your clarifications. Our scenery is a server side 
OSGI application, where application modules are hot deployed and contains 
their own GWT views and EntryPoints. 
Our main client GWT application has a dynamic side menu, with hyperlinks 
pointing to tokens associated with the external EntryPoints having views 
rendered in a main region.

MVP with multiple EntryPoints

2012-09-11 Thread Cristian Rinaldi

We have an application with multiple EntryPoints. Each EntryPoint contains 
an MVP configuration with their own PlaceHistoryHandler, PlaceHistoryMapper 
and PlaceController. Depending on the order that the history handlers were 
configured, the place treatment is overlapped. I think the problem is 
raised because the implementation of PlaceHistoryHandler invokes 
PlaceController.goTo(NOWHERE) when the PlaceHistoryMapper do not find the 
place, because this place is associated with the PlaceHistoryMapper of 
another EntryPoint. How I can solve this problem? It is right to use MVP 
with multiple EntryPoints?

Thanks in advance.

RequestFacory Validation issues

2012-08-08 Thread Cristian Rinaldi

Validation in the RequestFactory API is done only over Default group, and 
it is performed at the RF ServiceLayer level. It is not possible to map 
ConstraintViolationExceptions raised at the application level.
I have been analysing the SimpleRequestProcessor.process() method and I 
have concluded that it could be rewritten to support mapping of 
ConstraintViolationExceptions from the application level, and/or non 
default groups.
It is such feature in the GWT roadmap, or there is currently a way to solve 
this?

Regards.

Widget with Elemental support

2012-07-03 Thread Cristian Rinaldi

I understand that Elemental is esperimental, but is robust and really is an 
excellent frame.
My question is: In the future, Widgets are written using Elemental? Is it 
planned?

Re: GWT UI Layout

2012-06-12 Thread Cristian Rinaldi

I have built complex structures using LayoutPanel, gives much flexibility.
Also as Thomas said, you can animate transitions.

By example:
public void setDefaultLayout () {
  ...
  ...
  mainLayout.setWidgetLeftWidth (logo, 0, TCP 100, TCP);
  mainLayout.setWidgetTopHeight (logo, 0, PCT, NORTH_HEIGHT, PX);

  mainLayout.setWidgetLeftWidth (navigation, 0, TCP 100, TCP);
 mainLayout.setWidgetTopHeight (navigation, NORTH_HEIGHT, PX 38, PX);
  ...
  ...
  mainLayout.animate (500);
}

You are responsible for positioning the internal widget or panels.

Re: RequestFactory and query by example with a Proxy

2012-02-22 Thread Cristian Rinaldi

Thanks Brandon.

I'm using ValueProxy to send to the server.
Look at the code and the entities (EntityProxy) always validated regardless
of the method is called on the server (select or persist).
Perhaps the validation should performed only in methods that require it,
not always.

RequestFactory and query by example with a Proxy

2012-02-17 Thread Cristian Rinaldi

I am developing a filter to search for an entity.
The filter creates a proxy for the entity to seek, and then use this proxy 
with RequestFactory.
The problem is that the entity being validated do not know why.

The request is:
*Request > findByProxy (EntityBaseProxy proxy);*

Their counterpart on the server is:
*public List  findByProxy (EntityBase proxy) {
   Query query = em.get (). CreateQuery ("from EntityBase and WHERE 
e.namelike: arg1");
   query.setParameter ("arg1" proxy.getName ());
   List list = query.getResultList  ();
   return list;
}*

The error I am getting is as follows:

*Caused by: java.lang.RuntimeException: The call failed on the server due 
to aConstraintViolation 
atcom.google.web.bindery.requestfactory.shared.Receiver.onFailure 
(Receiver.java: 44) at com.google.web.bindery .

Place change dynamically

2012-01-29 Thread Cristian Rinaldi

I have a place that change dynamically but these changes are not reflected 
in the URL.

In the activity, a place with information is launched, but the mapper 
(CachingActivityMapper) needs to put other information, then I tried this 
code in the Mapper:

this.eventBus.addHandler( PlaceChangeEvent.TYPE, new 
PlaceChangeEvent.Handler() {
@Override
public void onPlaceChange( PlaceChangeEvent event ) {
Place newPlace = event.getNewPlace();
if ( newPlace instanceof PlaceTrace ) {
((PlaceTrace)newPlace).setPosition( 
CachingCenterActivityMapper.getKeyPosition() );
}
}
} );

but the handler is called after writing the URL.

Any suggestions?

Re: Editors with 2 forms

2012-01-26 Thread Cristian Rinaldi

Any idea over the problem?, all examples that I view, the sub-editors are 
just Widgets *without one Activity*, and the principal widget is also a 
Editor that is managed by your Activity or Presenter.

My principal problem is that my two Widgets are managed by your Activities, 
but the Widgets are dependent.

EntityBaseWidget is the principal widgets that have a logical list of 
Address, not a widget which represents a AddressList as a CellWidget or 
AddressEditor in the same page to to charge the list , only have a link to 
the new place ( NewAddressPlace ).
This place resulting in starting of Activity for Address and the 
initializations of AddressView respectively, that is a Editor in itself.
The Address entity need the EntityBase entity to be stored, but EntityBase 
not yet been saved, the idea is to link addresses charged in AddressView 
with the logical list in EntityBaseWidget
ie, that in some way by Editors can link each address charged with 
EntityBaseWidget logical address list.

1) I do not know whether to put a AddressWidget as sub-editor in 
EntityBaseWidget, but the beginning of AddressWidget is not the classic, is 
with the start method of an activity.

2) or in any way possible, share the editor context between views, and the 
worflow in EntityBaseWidget in combination with EntityCaseActivity handle 
the saving of everything (Address and EntityBase).

Re: Editors with 2 forms

2012-01-26 Thread Cristian Rinaldi

I explain more my previous question, 
I have a EntityBaseView and your UiBinder EntityBaseWidget implementation.
Your presenter is one Activity called EntityBaseActivity and exist one 
proxy called EntityBaseproxy where show the few methods:


EntityBaseproxy
---
String getName();
void setName(String);
.
.
List getAddressList();
void setAddressList(List);


--
The EntityBaseWidget implements EntityBaseView, Editor{


} 

--
Next I have a AddressView and your UiBinder implementation AddressWidget, 
with Activity and Proxys respectively.

The AddressWidget implements AddressView, Editor{


} 
--
Some methods of my AddressProxy are:
 
String getStreet();
void setStreet();

EntityBaseProxy getEntityBase();
void setEntityBase(EntityBaseProxy entityBase);
-


Some few explanations of the workflow:
In the EntityBaseWidget exist one button that call the NewAddressProxy, 
then the AddressActivity is started. In the AddressWidget I insert all 
Address in your property respectively.

If EntityBaseWidget have your list of Address(property), how link this 
property with list loaded in the AddressWidget?

I do not know how to model the composition of editors.

Editors with 2 forms

2012-01-25 Thread Cristian Rinaldi

I have a registration form for a person with addresses, but the directions 
will open in another form.
For each form I have an associated activity.
When I load an address (FormB), I need the person (FormA).
And in the form of the person, I need to go carrying the list of addresses.
As a link with editors, the data from this forms?.

Thanks.

Re: Editor Frame work and MVP

2012-01-20 Thread Cristian Rinaldi

According to a report by Martin Fowler, MVP has been withdrawn as a pattern
in July 2006, and has been divided into two variants: Passive View and
Supervising Controller.

*Passive View:* In this pattern, the view update is exclusively managed by
the presenter to reflect the changes in the model. The view never
interacts with the model. As we can see, this definition of the behavior is
not different from what was explained in the previous paragraphs. This
involves the benefits already stated, such as centering tests in the
controller (presenter), given that the view is a light component with
almost null logic content.

*Supervising Controller:* Many frameworks allow for the possibility of
making a mapping between the view and the model, called data
binding (Framework Editor). This is a very efficient approach which makes
it possible to
relate the model’s elements with the view’s elements through some sort
of declarative form. However, there are complex relations that require a
more complicated logic for the view.
In this pattern, the view interacts directly with the model to make a simple
data binding, which is declaratively defined without intervention of the
presenter. The presenter updates the model and handles the view state
only if the logic is complex and it cannot be expressed declaratively.

You can see this: http://martinfowler.com/eaaDev/uiArchs.html

Re: LayoutPanel and Custom Widget

2012-01-16 Thread Cristian Rinaldi

Hello:

The real question is: I have a widget to inherits of ComplexWidget with the
following declarations:

private Element root = Document.get().createDivElement();
private LayoutPanel header = new LayoutPanel();
private Image imgUp = new Image(getDefaultResources().imageUp());

header.add(label);
.
.
root.appendChild(header.getElement());
.
.
setElement(root);
sinkEvents(Event.ONCLICK);

Now I add a domHadler for image (the only event that interests me), but,
sinkEvents(Event.ONCLICK) register the event at level of element root, I
don't know how propagate the event at image, so that only the image, treats
you, and not the other elements of the widget.

I made this:

imgUp.addDomHandler(new ClickHandler() {

@Override
public void onClick(ClickEvent event) {
header.setWidgetTopHeight(imgUp, 0, PX, 0, PX);
header.setWidgetTopHeight(imgDown, 0, PX, 30, PX);
collapsed = !collapsed;
collapseBody(collapsed);
}
}, ClickEvent.getType());

But entire the widget  treats the event.

Any idea?

LayoutPanel and Custom Widget

2012-01-16 Thread Cristian Rinaldi

I am the following doubt:
I made a custom widget that use a LayoutPanel as container of elements:

  private Element root = Document.get().createDivElement();
  private LayoutPanel layoutBody = new LayoutPanel();
  private VerticalPanel body = new VerticalPanel();
  
  

 public MenuAccordionWidget() {
layoutBody.add(body);

layoutBody.setWidgetLeftWidth(body, 0, PCT, 100, PCT);  
layoutBody.setWidgetTopHeight(body, 30, PX, 90, PCT); 

.
.

root.appendChild(header.getElement());
root.appendChild(layoutBody.getElement());

setElement(root);

sinkEvents(Event.ONCLICK);
 }

The problem is heigth, but the layoutBody is hiden, need to know the pixels 
to get the percentage. But, I not want express the height in pixel because 
the height can change.

Any idea?

Other thing, is correct make a widget in this way, because it's like mixed 
the composite form with the low level way.

Thanks.

Hyperlink with PlaceHistoryMapper

2012-01-13 Thread Cristian Rinaldi

I have a problem with Hyperlink, this code is part of my View:

*New 
Task*

When I made a click over link, the URL change to: 

http://127.0.0.1:/main.html?gwt.codesvr=127.0.0.1:9997*#newTask*

But PlaceHistoryMapper never is called, therefore, my ActivityMapper never 
know the change of place *(#newtask)* and I can never start the activity.

Other places that do not use hyperlink going well.

Some code:

*AppPlaceHistoryMapper*
@WithTokenizers({DefaultPlace.Tokenizer.class, 
NewTaskPlace.Tokenizer.class}) 
public interface AppPlaceHistoryMapper extends PlaceHistoryMapper {
}


*NewTaskPlace*
public class NewTaskPlace extends Place {

public static class Tokenizer implements PlaceTokenizer {

@Override
public NewTaskPlace getPlace(String token) {
return new NewTaskPlace();
}

@Override
public String getToken(NewTaskPlace place) {
return "newTask";
}
}
}

*Part of CenterActivityMapper*

@Override
public Activity getActivity(Place place) {

if (place instanceof DefaultPlace){
HomeActivity activity = homeActivity.get();
return activity;
} else if (place instanceof NewTaskPlace ){
TaskActivity activity = taskActivity.get();
return activity;

}
return null;
}

Re: MVP understanding with Editor Framework

2012-01-12 Thread Cristian Rinaldi

It's easy to get confused when you think the MVP in the form of "Passive
View", but there is another version called Supervising Controller,
where the view interacts with the model to perform data binding,
the presenter, is relegated to attend more complexlogic, and we can
not express declaratively.

You can see this: http://martinfowler.com/eaaDev/uiArchs.html

2012-01-12 Thread Cristian Rinaldi

Hello:
  By example: if you work with RequestFactory the model in MVP means a
proxy, ie the DTO to be transmitted from the client to the server
according to your entities in the model.
  This proxy is mapped to the properties view. (binding).

Regards.!!

Re: Activities and Place design wizard

I need maintain the state between stages of wizard, therefore i need
caching the Activity. I read over CachingActivityMapper, I just wanted
to know if it was the appropriate solution.

Thanks for reply

Activities and Place design wizard

2012-01-10 Thread Cristian Rinaldi

Hello:

I have a question about the design using Activities and Places.
I have a set of activities that render their views in a section. 
The behavior I want is that each activity, after an event (by example: 
click in next button, click in activity represented in breadcrumbs)  go to 
the next activity, hiding the previous view.
Top of the section, I have a breadcrumbs with the activities that happened.
Now, if I click on one of the parts of the breadcrumbs, must be return to 
the activity related and show the view with all his state.
The question is:  I make a map of activities that are cached? or do not use 
cache, and management behavior in the start method of activity, starting 
all over again.
The view is singleton, and managed by GIN.
The general behavior is like the behavior of a wizard.

Any ideas?

Re: Editor not flush values of subeditors

Thanks thomas,

I see it clearly now.

It's a shame, I wanted the container interface does not depend on the 
particular implementation of Address. If this changes, I just wanted to 
change the bind in GIN.

Thanks.!

Re: Editor not flush values of subeditors

2011-10-27 Thread Cristian Rinaldi

The error is when I declare an interface instead of a particular class 
implementation.
By example:

@UiField(provided = true)
AddressView address;  //Interface (not a concrete class)

Note that into file ui.xml the inclusion of widget also is a interface

by example:



Now, when inject AddressView by constructor in the container view 
(TerceroNewEditor), and I asign the variable before that uibinder make a 
interface, aren't because Editor do not send values contained inside the 
AddressView.

Now, if I only change the declaration:

@UiField(provided = true)
AddressView address;

by

@UiField(provided = true)
AddressEditor address;  //implementation of AddressView
 
and either way that I assign (injection or direct  creation), Editor works 
well.

This is an error or is not covered?

Thanks and please, sorry for my english!!

Re: Editor not flush values of subeditors

2011-10-26 Thread Cristian Rinaldi

To test I created a new view for Address without presenter injected into
constructor.
And the Address View is not injected into the TerceroEditor view.

And things are just fine.

This works well:

   @UiField
  AddressEditor2 address;  *//AddressEditor is a concrete class.*

  private final TerceroNewView.Presenter presenter;

  @Inject
  public TerceroEditor(  *//Note: not inject sub-view AddressView, UiBinder
make a implementation*
  @Named(Constans.TerceroNewPresenter) TerceroNewView.Presenter
presenter) {

this.presenter = presenter;
ini();
  }

  private void ini(){
root = uiBinder.createAndBindUi(this);
res.erpLgkStyle().ensureInjected();
presenter.onCreate(this);
  }


TerceroNewEditor.ui.xml part:
   ...
   ...
   
   ...
   ...

//AddressView implements Editor

public class AddressEditor2 extends Composite implements AddressView {

  private static AddressEditor2UiBinder uiBinder =
GWT.create(AddressEditor2UiBinder.class);

  interface AddressEditor2UiBinder extends UiBinder
{
  }

  private HTMLPanel root;

  private AddressView.Presenter presenter;

  @UiField
  ValueBoxEditorDecorator address;

  @UiField
  ValueBoxEditorDecorator number;

  @UiField
  ValueBoxEditorDecorator code;

  public AddressEditor2() {
initWidget(uiBinder.createAndBindUi(this));
  }
}

If you inject the View with a Provider or AsyncProvider or directly not send
the information of Address.
This does not work:

   @ UiField (provided = true)
   AddressView address *//AddressView is a interface that
Implements Editor*

   private final TerceroNewView.Presenter presenter;

@Inject
public TerceroEditor(
  *Provider addressView,*
  @Named(Constans.TerceroNewPresenter) TerceroNewView.Presenter
presenter) {

   * this.address = addressView.get();*
this.presenter = presenter;
ini();
 }

private void ini(){
root = uiBinder.createAndBindUi(this);
res.erpLgkStyle().ensureInjected();
presenter.onCreate(this);
}


  TerceroNewEditor.ui.xml part:
   ...
   ...

//AddressView implemens Editor
public class AddressEditor implements AddressView {

  interface AddressWidgetUiBinder extends UiBinder {

Re: Editor not flush values of subeditors

2011-10-25 Thread Cristian Rinaldi

Thomas, thanks for the fast responce. I will see if this is causing the
error.

AddressWidget implements AddressView and Editor for AddressProxy, you say
that the AddressView must be extend Editor?


Now, one design question.

I love MVP, this pattern is very powerfull but, with Activities and Place
some thing are dificult.

Activities are for when you need navigation, but if want each view has a
Presenter, I thought the following:

   One interface Presenter for each View, where "View" delegate the logic in
the presenter implementation.
   Now, presenter is not Activity. When I need navigation, I make a Activity
that inject the presenter and delegate in this the logic of View.

   I want keep separate in the best forms the concepts of view and
presenter, but I want to know if inject the presenter in view is ok.
  The presenter have a method called onCreate(T) where T is a View. That
method is called when View is initialized after make UiBinder interface.
  In the onCreate(T) I inicialize the editor driver, etc.

  When I precise a Activity, in the start method I obtain the view, by
example, with AsyncProvider, how the View inject Presenter, the Activity
delegate logic to Presenter.

 I started think this for nested complex widget, for example, load Employees
associated with bank accounts, where the Widgets for list of selection and
creation bank account is a widget that delegate logic in a presenter that is
not Activity.
 But, i can use this widget alone in other view where is necesary one
Activity.

  All this is fine or I've gone crazy?

  Sorry for my english.

Re: Nested Editor creation question

2011-10-25 Thread Cristian Rinaldi

Hello:

Suppose you have a UserView interface, then you can use the interface instead 
of the concrete class.

class UserEditor ... {

..
..
UiField (provided = true)
UserView view




  @ Inject 
  UserEditor (UserView v) {
this.view = v;

UiBinder initialization 
  }
}


where:

  class UserViewImpl implements UserView {
 
 
  }

By example with GIN:
   bind(UserView.class).to(UserViewImpl.class).in(Singleton.class);

Now, as says Aidan, if you not use GIN or other IOC, (provided = true) it 
is not necessary, UiBinder does it for you.

with flush is called in method save of *TerceroNewEditorPresenter*. The
unique values that are sent, are those that correspond to *Tercero (name and
lastName). *

 Attached files to see and guide me in the error.

 Thank you very much and sorry for my English.

java.lang.NoClassDefFoundError:org/json/JSONException

2011-09-16 Thread Cristian Rinaldi

I have an error when the application is deployed.
The exception is "Caused by: java.lang.NoClassDefFoundError: org/json/
JSONException". But the rare is that I have all libraries in de WEB-
INF/lib

gwt-servlet.jar
gwt-servlet-deps.jar
requestfactory-servlet.jar
validation-api-1.0.0.GA.jar

I'm not using maven and ther version of GWT is 2.4.

Thanks

Re: multi pages in gwt

2011-08-29 Thread Cristian Rinaldi

What is the reason to have multiple pages? (HTML Pages)
Ajax applications respond to the pattern Sinlge Page.
You can manage the content to be displayed using MVP (Place / Activities).
