Hello,

When I use the "trick" to add a string parameter called "GERRIT_REFSPEC" with "refs/heads/master" as default value (described here: https://wiki.jenkins-ci.org/display/JENKINS/Gerrit+Trigger), I can't click on the "Launch a build" button.

I get this error: "Method not allowed: The requested method GET is not allowed for the URL /job/HelloWorld/build". This does not happen if the parameter is not set (even if the build fails, which is only logical).

Thank you for your help
