Hi all,

Hot on the heels of Groovy 1.6, we’re pleased to announce the availability of Grails 1.1 RC1. It can be downloaded from the usual spot (http://grails.org/Download) and as usual there are comprehensive
release notes available (http://www.grails.org/1.1-RC1+Release+Notes).

The main features are now stabilized and include:

- Support for Ant+Ivy and Maven builds
- Standalone GORM
- New plugin features: global plugins, transitive plugin resolution, local repositories etc.
- Spring namespace support
- Dramatically improved performance
- The Testing framework.
- Many new features and incremental improvements to core Grails features such as GORM and the MVC layer

At this stage we really encourage people to try the release out and report any issues. If there are a significant number of changes we will of course do a second release candidate, however we are reliant
on the community for feedback. In particular if plugin developers could try the release against your plugins to ensure compatibility that would be of great assistance. As usual any problems found should be reported to JIRA:

http://jira.codehaus.org/browse/GRAILS

Enjoy!

Hi all,

This is with very great pleasure and honor that I’m announcing the final release of Groovy 1.6, on behalf of the Groovy development team and SpringSource.

Obviously, 1.6 is a very important milestone for the project, with several great new features and improvements:
- great runtime performance improvements
- multiple assignments
- optional return in if/else and try/catch blocks
- AST transformations and all the provided transformation annotations like @Singleton, @Lazy, @Immutable, @Delegate and friends
- the Grape module and dependency system and its @Grab transformation
- various Swing builder improvements, thanks to the Swing / Griffon (http://griffon.codehaus.org) team
- as well as several Swing console improvements
- the integration of JMX builder
- JSR-223 scripting engine built-in
- various metaprogramming improvements, like the EMC DSL, per-instance metaclasses even for POJOs, and runtime mixins

An article will be published in the coming days on InfoQ (http://www.infoq.com) and GroovyMag (http://www.groovymag.com) coming back on all those features and novelties with more details.

You can download Groovy 1.6 at the usual place:

http://groovy.codehaus.org/Download

Additional installers and bundles will be provided soon.

And you can also have a look at the JIRA changelog listing features,improvements and bug fixes:

Very big thanks to all the developers who contributed to the project, in particular our most prolific ones like Paul, Roshan, Danno and Jochen, and to all our users who’ve helped shape the project, thanks to their great feedback and suggestions.

Let me also mention an interesting event which is shaping up: the GR8 Conference, a conference dedicated to Groovy, Grails and Griffon, organized by the Danish JUG and SpringSource!
You can learn more about the event on the conference website:

http://www.gr8conf.org

Or by following the twitter account: http://twitter.com/gr8conf
The conference takes place in Copenhagen, Denmark, and will provide several practical sessions and ands-on labs to get you up-to-speed on those great Groovy-based technologies.

The registration should be open in the coming days, so get ready!

Enjoy!

Temos uma tabela usuário que a chave PK é uma String(quem já não viu isso ??), como por exemplo : login_usuario, valor que é determinado pelo sistema e não definido por nenhum gerador automatico(sequence, UUID, etc). Tive muita dor de cabeça para descobrir como fazer isso, e a dica é a seguinte :


class Usuario {
String id ----> sobrepõe o tipo de atributo para String e não o default
String nome
String senha
....
static mapping = {
table 'usuario'
version false
id generator:'assigned', column:'login_usuario', type:'string'
...
}
}


Dear Groovy/Grails Community, 

We are pleased to announce the release of Grails 1.1 beta 3! This 
release provides a number of new features and improvements over the 
second beta. The headliners are: 

* Ant + Ivy Support – Grails applications can now be built on any 
continuous integration server that supports Ant without the need for a 
local Grails installation 
* Spring Namespace Support – Grails’ Spring integration has been 
extended to support Spring namespace-style configuration 
* Support for server-side forwards and includes – You can now perform 
forwards and includes from controllers and tag libraries 
* Standalone GORM – GORM can now be used outside Grails and an example 
that uses Spring MVC is provided with the Grails distro 

A more detailed run down of all the features added so far can be found 
in the release notes at http://www.grails.org/1.1-beta3+Release+Notes 

Alternatively you can take a look at all the issues resolved at the 
JIRA changelog:
