Re: Event.stopPropagation() not working for KeyDownEvent

[Thad Humphries]

I've succeeded by removing the KeyDownHandler and adding this in my login 
widget:

Event.addNativePreviewHandler(new Event.NativePreviewHandler() { 
  @Override 
  public void onPreviewNativeEvent(NativePreviewEvent event) { 
Event nativeEvent = Event.as(event.getNativeEvent()); 
int c = nativeEvent.getKeyCode(); 
if (c==KeyCodes.KEY_ENTER) { 
  event.consume(); 
  login_btn.click(); 
} 
  } 
});

The alert's onPreviewNativeEvent() is unchanged.

Re: java.lang.NullPointerException Error when using rpc

[Thomas Broyer]

Looks to me like this is saying your server-side code throws a 
NullPointerException, so you get it on the client-side.

Re: IntegerBox and Editor framework question

[Thomas Broyer]

You could also:


   - use another editor (possibly wrapping or delegating to an IntegerBox) 
   that makes sure getValue is never 'null', or
   - make the "parent" editor a ValueAwareEditor and handle the field 
   binding manually in the setValue() and flush() methods

Re: Implementation alternatives to improve GWT RequestFactory read and write based use cases

[Thomas Broyer]

The way RequestFactory is designed, you have to use per-request caches to 
ensure you only ever have one instance of a given entity within the course 
of the request. Using Hibernate/JPA, that means using a session-per-request 
(aka open-session-in-view) pattern. Are you already using it?

Re: Native File Chooser Dialog

[Thomas Broyer]

It could be that the browser only shows the dialog when processing a 
user-initiated event (there was something like this introduced in Flash 10 
back in the days for security reasons: 
http://www.adobe.com/devnet/flashplayer/articles/fplayer10_uia_requirements.html
)
Try with "vanilla JS", and if it behaves the same, then at least one could 
say GWT is not to blame.

Event.stopPropagation() not working for KeyDownEvent

[Thad Humphries]

I have a user login form that I want submitted if the user presses ENTER in 
the password field or clicks the login button. So I add a KeyDownHandler:

KeyDownHandler kdh = new KeyDownHandler() { 
  @Override 
  public void onKeyDown(KeyDownEvent event) { 
if (event.getNativeKeyCode() == KeyCodes.KEY_ENTER) { 
  event.stopPropagation(); 
  login_btn.click(); 
} 
  } 
}; 
password.addKeyDownHandler(kdh); 

The login button calls the presenter to doLogin(). Before sending the 
request to the server, the method checks that the fields are filled in. If 
not, an alert is popped up.

I want this alert to hide on ENTER or ESC, so the alert has a method:

@Override 
public void onPreviewNativeEvent(Event.NativePreviewEvent event) { 
  Event nativeEvent = Event.as(event.getNativeEvent()); 
  int c = nativeEvent.getKeyCode(); 
  if (c==KeyCodes.KEY_ENTER || c==KeyCodes.KEY_ESCAPE) { 
hide(); 
  }
}

Problem: The alert pops up and disappears all on a single ENTER.

Why isn't Event.stopPropagation() stopping the ENTER key? Why should I even 
need to try since the alert is only created when the error is detected? How 
can I accomplish this (other than Window.alert())?

Re: Determining dependencies for split points

[Ben Klein]

The solution that worked for me was to move the code from the runAsync 
method of split point 1 out of the runAsync call (next to it). This put the 
relevant code into the initial download part, where I could trace the 
dependency.

CellTable keyboard events troubles in Chrome

[yves]

Hi All,

After a search on the internet and in this group I didn't found help for 
the issue I have. 
So I ask here if someone has any advice or workaround.

I just tried basic example of CellTable found here 
http://www.gwtproject.org/doc/latest/DevGuideUiCellWidgets.html, and put 
the cellTable in an empty VerticalPanel somewhere in my app.

In Chrome only, the example doesn't work correctly : almost all keyboard 
events have no effect. Only Delete, Backspace, CTRL-Z + other CTRLs and 
ENTER keys work. It is impossible to type in some text : alphanumeric key 
events have no effect on the content of the cells.

With other browsers than Chrome the CellTable example works without any 
problem !

For the test I use :
GWT 2.5.1
Test NOT OK : Chrome 32.0.1687.2 dev-m Aura
Test OK : Firefox : 24.0
Test OK : Opera : 12.11
Test OK : Safari : 5.1.7
(no test on IE as I have only IE6, for other tests purpose...)

Thank you for your help.
Yves

Re: Logging to the server side

[Greg]

Hi

You may check this first: 
http://www.gwtproject.org/doc/latest/DevGuideLogging.html especially this 
section: 
http://www.gwtproject.org/doc/latest/DevGuideLogging.html#Remote_Logging
Then this: 
https://gwt.googlesource.com/gwt/+/master/user/src/com/google/gwt/logging/server/RemoteLoggingServiceImpl.java
 - 
it's a source for GWT-RPC service which allows remote logging on the server.

As the documentation says: "GWT currently contains a SimpleRemoteLogHandler 
which 
will do this in the simplest possible way (using GWT-RPC) and no 
intelligent batching, exponential backoffs in case of failure, and so 
forth." So it's possible but you have to implement it yourself.

Re: Problems with super dev mode: Can't find any GWT Modules on this page

[Greg]

Hi

I had similar issue lately. Important thing is that after switching to 
xsiframe linker you have to compile your application and use it for 
starting sdm. This way your app.nocache.js file will be built by that newly 
set linker and sdm scripts will detect it. Without that step nocache.js 
file will be old (created by std linker) - hence the error.

Good thing after changing linker is cleaning the project (and also removing 
gwt-unitCache folder). Without doing it I had some compilation issues.
