Re: Gwt maven archetypes

You are right.. This can be ignored. 

Actually, real problem that I had is that after login I couldn't see main 
screen with text box and button that says hello to server.

I debugged and found that problem is with User interface.

When calling* user.getUserName() *browser throws this exception:

Uncaught Error: com.google.web.bindery.event.shared.UmbrellaException: 
Exception caught: (TypeError) : user_0_g$.getUserName is not a function

To fix this I had to add *@JsProperty* to interface methods which is 
properly translated to javascript *user.userName* instead of calling a 
function.

this is the fix:

import jsinterop.annotations.JsProperty;
import jsinterop.annotations.JsType;

@JsType(isNative = true)
public interface User {
@JsProperty
String getUserName();

@JsProperty
boolean isAdmin();
}

Re: new GWT Platform Errai by JBoss ! what do you think ?

2017-05-04 Thread Олег Рачаев 
IMHO.

One black box inside the other. I don't think it's a good idea. Even pure 
GWT is very difficult to know what to say about the framework is built on 
the basis of the GWT.

It's not an error, it's an information.

The archetype does not make use of JSR 303 Bean Validation, but 
RequestFactory looks for a validator anyway and emits this message.
You can configure logging (java.util.logging) to get rid of the message, or 
if you intend to use Hibernate Validator (is there any other JSR 303 
implementation out there?) then the message will go away as soon as you add 
the dependency.

Re: Loading only relevant shared code in an html page.

2017-05-04 Thread Thomas Broyer 
You have 2 possibilities (that I haven't explored personally, so I couldn't 
comment on the pros on cons)

   - use a single entry-point (single module), and use code splitting 
   (GWT.runAsync) to only load what's needed (and probably a bit more that'd 
   happen to be shared with other pieces of code; in so-called "leftover" 
   chunks); shared code between "pages" will then really be shared (at the 
   HTTP/caching level)
   - use one entry-point (one module) per "page"; code shared between 
   several modules will be included (duplicated) in each generate script 
   though, with absolutely no sharing. And yes you can have as many as you 
   like. I'm not aware of any limitation in the GWT Eclipse Plugin, and even 
   if there was, I'd highly recommend using a build tool (Gradle, Maven, Ant, 
   or even Make if you like) that will *not* have any limitation (or at least 
   whose limitations could be worked-around). Actually, the thing you'll have 
   to balance will be between running the GWT compiler once with all the 
   modules in argument vs. once per module, I'd say *a priori* a balance 
   between memory and time.

Unfortunately, GWT 2.x cannot have the best of both worlds (one "entry 
point script" per page, with code-sharing between modules) like, say, 
Webpack can do.
(see 
PRPL https://developers.google.com/web/fundamentals/performance/prpl-pattern/ 
, Webpack entry-points 
https://webpack.js.org/concepts/entry-points/#multi-page-application and 
CommonsChunkPlugin https://webpack.js.org/plugins/commons-chunk-plugin/ )

Loading only relevant shared code in an html page.

2017-05-04 Thread NxS 
Hello,

I'm a GWT newbie.

1. Is it possible to load only a subset of a module's shared code in an 
html page, declaratively or otherwise? 

Use-case: I may have a lot of shared code in my overall application, not 
all of which may be relevant to every single html page (of my overall 
application). So, I'd like to be able to load only select portions of the 
shared code in a given html page, ignoring portions of it not used by the 
page.

2. If the above is not possible, then... Is it possible to have multiple 
modules in a single Eclipse project, using either the Eclipse IDE or the 
webAppCreator command-line tool? 

The idea is this: 

IF I have a total of 1 methods in my overall application's shared code, 
AND 
IF I have 100 pages each requiring 100 methods only (on average),
THEN, I wouldn't want to create 100 different Eclipse projects for these 
100 modules (consisting of 100 functions each) when a single Eclipse 
project could well do the job.

Thanks and regards,
NxS

PS: When I say "load" above, I mean loading of the code by the browser, 
generating a proportional amount of network traffic.
