I have now, but the badge is not updated. At least, when i follow the assignment link, then it says that i have agreed with it.

@aulea : sorry for the late reply. It sounds very strange that the CLA does not update after your signature. I've tried it before, where I accidentally made the commit using my work email instead of my private email that I use for my Github account. Try to verify that the emailaddress in the commit matches your GitHub account - you can see the commit email address here: https://github.com/grails/grails-core/pull/12446/commits/9090187197d96cc0939feb69810e65b128015a01.patch

[aulea]

you were right, it was committed with different email address

Thank you for the pull request. I am currently working on merging these changes manually. Also, I think we should use Groovy org.apache.groovy.ast.tools.ClassUtils.addGeneratedMethod(ClassNode cNode, MethodNode mNode) instead of explicitly calling AnnotatedNodeUtils.markAsGenerated(classNode, method);.
