I have an existing job (job1) which is configured to poll SCM every minute.
Now I create a new job (job2) and I select "copy existing job" and I specify "copy from job1"
As soon as I hit OK I get the job configuration page.
Now I start making a few edits to the job configuration page and I notice Hudson just started a build for job2 but I never had a chance to save my edits.
