GWT 1.5 Milestone 1 now available for download

[Bruce Johnson]

Hi everybody,

GWT 1.5 isn't finished yet, but it is starting to get close. I'm happy to report that the first milestone build of GWT 1.5 is now available:

   http://code.google.com/p/google-web-toolkit/downloads/list?can=4&q=version%3A1.5+quality%3Amilestone

(Note the odd version number of 0.0.2030 to help make it obvious that you shouldn't use it for anything important.)

For milestone builds like this, please understand that there are still known problems, and it is use-at-your-own-risk. It *definitely* isn't ready for production use. For example, this milestone build is missing release notes, and it doesn't include the developer guide documentation. So, you should expect some trial and error getting everything to work.

Are your expectations low enough yet? Well, I also have some good news about what's included in this milestone:

• The Java 1.5 syntax is fully supported, including generics, enums, nice "for" loops, autoboxing, static imports, annotations, and so on
• Support for generics in RPC (no more @gwt.typeArgs!)
• The ability to subclass JavaScriptObject for very straightforward JavaScript interop
• Standards mode is now supported by the UI library (though there may be a few remaining bugs)
  

There are lots of other neat things in there if you dig a little. You can see details in the issue tracker, or if you're really interested (or really bored), you can browse the commit logs.

Things to be aware of that may trip you up:

• GWT 1.5 requires Java 5 or later
  
• The compiler output now goes into a subdirectory (e.g. ".../std" or ".../xs", depending on your linker settings)
• To encourage people to start using annotations and generics instead of the javadoc metadata, you'll see warnings about uses of old-style metadata such as @gwt.typeArgs; it is intentionally annoying :-)
• The benchmark classes have moved into a separate package; should be easily fixable using your IDE's auto-import fixup
• As a performance improvement, widgets now often call DOM.sinkEvents() lazily, when listeners are actually added rather than in the constructor. Sometimes, widget subclasses implicitly depend on the set of events sunk in the superclass' constructor. Consequently, if you are overriding onBrowserEvent() in a widget subclass and certain events mysteriously stop firing, you should explicitly call DOM.sinkEvents() in your subclass constructor for the events you depend on (don't worry, sinking an event more than once has no effect). If the preceding sentences made no sense at all to you, then you shouldn't be affected.
  

We really hope you'll try it out, and we 're eager to see what you think so far. Please report bugs in the issue tracker, and discuss it in the contributors forum.

Enjoy!

-- Bruce, on behalf of the GWT team

Bruce,
  Thanks for including a separate Leopard build in the main distribution.

-Ray

[Bruce Johnson]

As much as I'd like to, it was all Kelly. Thanks Kelly!

[Ray Cromwell]

Scott,
  The new JSO subclassing ablity is supposedly part of this milestone, but I didn't notice any JsField/JsMethod/etc annotations in the distribution. Are these going to be in the .core package somewhere, or within JSO scope in the future, or are these going to be part of a separate JSIO package? I thought these annotations were going to be special first class citizens/instrinics that GWT treated specially.

Congratulations.

This is a long-awaited version.
The only I miss is the support of BigDecimal. I created
http://code.google.com/p/google-web-toolkit/issues/detail?id=1857&q=BigDecimal
for this issue.
BigDecimal is more important for financial applications.
Can you add this issue for the final 1.5 version?

Thanks a lot.

enough for you Emilio ?

I just downloaded and unpacked the Linux version. The first thing I
did was open gwt-module.dtd in gvim and I see a whole bunch of ^M
characters all over the place. Not a big deal--I'll probably never
open that file again anyway--but it'd be cool if the Linux version of
the text files were run through dos2unix before archiving them.

This is great. I had a problem compiling with i18n, all the xxx.properties lines

with a ' (single quote) caused it to fail.

 

      Rebinding com.parvia.common.client.i18n.messages
         Invoking <generate-with class='com.google.gwt.i18n.rebind.LocalizableGenerator'/>
            Processing interface com.parvia.common.client.i18n.messages
               Generating method body for home_motto()
                  When locale is 'default', property 'home_motto' has the value 'it's small here'
                     Failed to parse the message it's small here so cannot verify the number of passed-in arguments

 

If I take out all the ', it compiles fine.

If I take out all the ', it compiles fine.

If this is a Messages subinterface, the strings are in MessageFormat format.  That means that quotes have to be doubled, as they are used to quote braces.  For example:

• don''t tell me that
• '{0}' this brace is commented, {0} this is not
  

The old version improperly parsed a number of strings and did not properly warn on certain errors.  It will be improved further when the i18n changes are committed.

Ray, that stuff isn't in yet.  It's really just syntactic sugar anyway-- the core functionality you need is in, and you can write the JSNI by hand.

[GeekyCoder]

To GWT team,

GWT 1.5/1.4 is great. The only issue is the compilation is taking
quite noticeably slow as application can more complex even as I
running it in Core 2 1.7GHz CPU with 2GB ram. I do understand it is
perform complex permutation to optimize the javascript. Still, is
there any way to improve the compilation speed ?

For a moderate application, it is taking around 15 sec to compile.
thx

Good Job !!!!!!., works fine.

Thanks a lot.

[Arthur Kalmenson]

15 seconds isn't bad, it takes over a minute on my machine (albeit
it's a crappy Pentium D). One way around it is to check your work in
hosted mode but have a regular build that'll deploy your application.
So when you want to make sure it works in a number of browsers (if
you're not using Selenium), you'll probably have the latest build
already up and running.

I am experiencing a problem with the Mac 10.5 version. Specifically:

[ERROR] Errors in 'jar:file:/Users/kebernet/Applications/gwt-
mac_10.5-0.0.2030/gwt-user.jar!/com/google/gwt/emul/java/util/

[ERROR] Missing message: compilation_internalError in:

java.lang.NullPointerException

Anybody else seeing this?

You can also reduce the number of deferred binding permutations by using <set-property> during development.

I am using JSON and in 1.5 I am having problem in working with JSON.
Well I didn't try that code in 1.4 as I wrote that today only.
Here is the error that I get:

So does anyone know what can be the problem?
I also can't switch to 1.4 because I have problem with the bug 1702
[http://code.google.com/p/google-web-toolkit/issues/detail?id=1702]

Any help would be great.
Thanks.

The only thing I can tell you for the moment is that the hosted mode
startup time used to be around 30 seconds with GWT 1.4.
With 1.5: 11 seconds !
Once again: excellent !

[P.G.Taboada]

A few days ago I noticed the archtictural changes concerning the
Linker and the new output folder hierarchy. Is there more
documentation about this new feature?

Just wondering: Is any one already working on an Adobe Air Linker and
integration module?

At the Wrap-Up in GWT Conference last year it was clearly stated that
documentation would improve with 1.5 - what is the status here?

My compile times went seriously south :(

With couple of weeks old build from trunk compile was around 14
second, now with M1 it takes 45 seconds.

Can you reproduce this faithfully? If it's truly a slowdown that was introduced within the last two weeks, we might have a chance of being able to mitigate it before final.

It seems that this slowdown only affects one module, other compiles
work ok. If nobody else is experiencing slowdowns i have to assume
that it's caused by the module, which btw has not been updated to 1.5
language level yet and has also tons of @gwt.typeArgs deprecated
warnings. The module is something like 500+ classes so updating it to
1.5 language level is going to take bit of time. If that does not fix
the speed i'll email back and/or open an issue, but for now i think
you can assume this is an isolated problem.

If you are indeed generating hundreds of log messages, that could account for some of the slowdown.

[AndyG]

What are chances of getting some kind of switch to suppress those
typeArgs warnings? I am using a 3rd party GWT-based widget library
which (given that GWT 1.5 isn't officially released yet) is still
using the old idioms. It makes finding the real compile / runtime
errors among the noise difficult.

AFAICT this release doesn't contain stuff from the incubator project.
Will 1.5 final?
