Well, not really a fix. More like an enhancement.
Currently the only available grails-maven-archetype will generate a grails 1.2.0 project. There have been several fixes applied to Grails 1.2.2 and I wanted to take advantage of these. I have commented on the issue requesting a grails 1.2.1 archetype, but I updated it all the way to Grails 1.2.2 (The attachment is at the top of the bug, and the comments don’t reference the attachment at all, silly Jira.)
