GWT 2.1 RC1 is now available

Posted by Chris Ramsdale - Monday, October 11, 2010 at 6:50:00 PM

Building on the three previous milestones, we're happy to announce the first release candidate (RC1) of GWT 2.1. While we're still focused on the overall theme of making it easier to build cloud portable business apps via some help from our friends at VMware and Spring, there are more than a few aspects that make this milestone a RC.

First we've rounded out the list of components and features that will ship with GWT 2.1. One of these components is a new Editor framework that allows you to bind your DTOs to a customizable UI which handles all of necessary grunt work of validating and syncing change sets. Another is the availability of the SafeHTML component and its integration within the cell-based widgets. After all, we've optimized these new widgets by injecting HTML, we better do it in a secure manner.

Along with the new components and features, we've solidified the Activities/Places, RequestFactory, Editor framework, and Cell-based widget APIs. So, if you're looking to start a project with GWT 2.1, you can feel confident that your team won't have to refactor code because we've switched out interfaces between now and the final release.

Also, if you're looking to get started with GWT 2.1 we have an initial draft of the new Developer Guides. These can be found at the links below (the Editor framework Developer Guide is coming soon).

As with previous milestones, to get the full effect, you'll want to pick up the Spring Roo RC1 and SpringSource Tool Suite RC1. Ben and Christian from the SpringSource teams have been hard at work adding features and functionality, and it's great to see that we're all very close to the final release.

GWT 2.1 RC is available on our Google Code download site and as version 2.1-SNAPSHOT in the Google Maven Snapshot Repository. We’d love to hear your feedback and thoughts on this release, and our GWT Developer Forum would be the best place to post this information.

This is a Dream come true! Thank you. I can't wait to read more about that Editor Framework.

Do the "Cell-based widgets" support column sorting, as-you-type filtering and/or cell merging?

These are welcome changes.

GWT seems to be improving well, and works nicely with other libraries.

When will 2.1.0.RC1 be available on the central maven repository? I 'd love to run some experiments with that CellTable (and file issues if I find any of course).

Great work,coding with GWT is fun!
I am using GWT 2.0.4 and I am bit worried about making an upgrade or not because I do use gwt-presenter and gwt-dispatch in my project.
Will GWT 2.1 impact this?

Asgeir Frimannsson said...

Would it be possible to publish this in the google-releases maven repository as 2.1.0.RC1 rather than the moving target that is 2.1-SNAPSHOT?

Baloni said...

Is there any roadmap for 2.1 release? Cell-based widgets are the best thing for me.

Gwt developers need sources for learning it -books,tutorials etc... .Until there won't be more sources for learning, I will use flex.

Asgeir: I 've created an issue, feel free to star it (vote for it):

Deploy RC releases as non-SNAPSHOT's in the maven repository google-releases (for example 2.1.0.R1 instead of 2.1-SNAPSHOT)
