Hi There.
I'm also interested in this project, and I've started to update it.
I've already got it compiling against wicket 1.3.2 and the maven infrastructure working with the latest m2eclipse plugin.
Nest stage is getting the example to work.
and renaming the packages.
I've forked the project off of the svn repo and opened a GIT repository here:
http://github.com/astubbs/wicket-contrib-groovy/tree/wicket1.3CompilecompatInstall git from
http://git.or.cz/and then
git clone git://github.com/astubbs/wicket-contrib-groovy.git
git checkout -b w1.3 origin/wicket1.3Compilecompat --track
And that will give you the latest. I'm doing the development on a branch at origin called wicket1.3Compilecompat. you can name your local copy (w1.3 in this case) anything you want.
Any help welcome!
