    After updating Multijob plugin to version 1.22, I cannot see the content of Multijob view. With previous version 1.21 it works fine. This doesn't affect the job functionality, only the view content. Here's the stack trace that is printed to the web page when rendering the view: javax.servlet.ServletException: org.apache.commons.jelly.JellyTagException:
