[gwt-contrib] Re: Experimental release of Elemental2

[Luke Last]

What's the best way to type cast objects? I get a ClassCastException in 
super dev mode with the following.

ArrayBuffer ab = (ArrayBuffer) fileReader.result;

The exception stems from com.google.gwt.lang.Cast#castToNative

If I use JSNI to perform the cast it works fine.

Thanks for working on Elemental2. I think it's super important for GWT.

GWT 2.8.0 RC2 is here!

['Daniel Kurka' via GWT Users]

Hi all,

I just build the GWT 2.8.0 RC2 and pushed it to maven central. The complete 
SDK is also available from here .

Please start testing and let us know if you run into any trouble and file 
bugs .

We are planing to release this as GWT 2.8.0 if we do not here about any 
serious issues within the next two weeks. The release notes for RC 
2
 will 
be made available shortly after this notice, in the mean time you can take 
a look at the github repository 

.

Problem with 2.8.0 rc1 SDM

[Alberto Mancini]

Hello,
in the attempt of porting an internal project from beta1 to rc1 we faced an
issue i do not understand how to debug.

The project uses errai but my feeling is that the problem is not related to
it because similar projects with errai work without problems.

Essentially SDM fails during the first compilation and the problem seems in
the generation of the source maps.

The relevant error log follows.

Re: GWT 2.7 - MultiModule Setup and SDM recompilation

[Daniel Kurka]

Even at Google for really large projects recompile times do not exceed
15seconds. So something is wrong in your setup since we only do recompile
changed files after the first compile.

Are you giving enough ram to SDM?
Are you really only changing a few files (or is something else updating
timestamp on these files)?

Poker Fighter: Project coded in GWT

[Guy Sela]

Hi Guys,

You're welcome to explore and comment about my product which was almost 
100% coded in GWT:
http://www.poker-fighter.com

This link leads to the homepage, and clicking "Play Now" will lead you to 
the game itself, which was built in GWT.
If you have any questions about the design or implementation, feel free to 
ask!

Try to use 2.8 snapshot for SDM and the stable 2.7 release for production,

fixed missing words:
I just tested your example. THIS compiles and works but when trying to add 
a default (or static) to a requestfactory proxy i get the said errors. 
maybe the requestfactory apt processor is not correctly updated to the new 
features?


e.g. this inteface:
@ProxyFor(value = Test.class)
public interface TextProxy extends ValueProxy {

default String getTest() {
return "";
}

static String getTest2() {
return "";
}

}


generates the following errors:
Could not find domain method similar to java.lang.String getTest() 
Could not find domain method similar to java.lang.String getTest2() 

when removing the "get" ( having "test()" and "test2()") it has those 
errros:
Could not find domain method similar to java.lang.String test()
Could not find domain method similar to java.lang.String test2()
Only getters and setters allowed
