I haven’t worked on my Grails project (an Online Store example application) for a few weeks, but I had a couple of days off work this week so spent a number of hours working on some new features.

I found an issue with the pagination support when using results sorted in reverse id order and logged bug GRAILS-914.

I also came across an issue that I couldn’t work out – I had some error in one of my Controllers but the problem was being masked by the error.jsp page not functioning correctly. It looks like this was fixed in GRAILS-365 in 0.3, but I was still seeing this issue in 0.3.1. I logged a new bug report for it (GRAILS-919), and decided to upgrade to 0.4.2 at the same time.

After upgrading to both Groovy 1.0 and Grails 0.4.2 (running ‘grails clean’ and ‘grails upgrade’ on my existing app), I found a number of things I needed to change in my existing code, which I captured as separate posts here:

1. @Property annotation removed
2. Domain class constraint ‘length’ deprecated in Grails 0.4.2

Plus a couple of other helpful tips:

1. Changing the default list method
2. Linking to other actions from a view page
3. Using pagination with Controller action other than the default list

It has been speculated for a few weeks now that Sony was about to announce movie, tv and music downloads on the PS3, via an initiative called ‘Home’. Turns out ‘Home’ is more than just that – it is a fully immersive interactive virtual world where you can interact with any other online user, and all of your media content.

ign.com have a walkthrough of the new service incluing screen shots – it looks pretty awesome so far. Think ‘Second Life’ in HD coupled with Nintendo’s ‘Mii’ concept on steroids. Think XBox360’s ‘Achievment Points’ for achieving in-game goals – now take that an visualize the whole concept in a 3D interactive world where you walk through your virtual trophy room to view all your game rewards. Mix all these concept together, and this gives a picture of what ‘Home’ is all about.

A promo video of Home can be seen here.

It will be making a beta appearance early this year, but expect to see it in it’s completed full version in fall this year.

Daylight Savings Time changes on March 11 this year. Patches have been released for older versions of the Java platform to make the platform aware of this date change – further details are available here.

Details of Sony’s new online service ‘Playstation Home’ will be discussed at the Game Developers Conferenece today.

The new service is expected to bring movie, tv and music downloads to the Playstation Store accessible via a PS3 online. More details are expected to be released today during the Game Developers Conference.
