Description of problem: I was trying to register a system from UI. I entered the system name, arch and system type "Virtual" and clicked on save button. On clicking on save button, nothing happen on UI. However following notifications are generated: 2011-11-18 09:29:14 error Render and/or redirect were called multiple times in this action. Please note that you may only call render OR redirect, and at most once per action. Also note that neither redirect nor render terminate execution of the action, so if you want to exit an action after redirecting, you need to do something like "redirect_to(...) and return". Version-Release number of selected component (if applicable): [root@dhcp201-143 packages]# rpm -qa | grep katello katello-glue-pulp-0.1.110-2.el6.x86_64 katello-configure-0.1.15-1.el6.noarch katello-cli-0.1.13-1.el6.noarch katello-common-0.1.110-2.el6.noarch katello-0.1.110-2.el6.x86_64 katello-all-0.1.110-2.el6.x86_64 katello-cli-common-0.1.13-1.el6.noarch katello-glue-foreman-0.1.110-2.el6.x86_64 katello-glue-candlepin-0.1.110-2.el6.x86_64 [root@dhcp201-143 packages]# How reproducible: always Steps to Reproduce: 1. Select system tab --> new system 2. Enter name of system, arch and system type 3. save Actual results: Nothing happens on UI after clicking the 'save' button. And if you traverse to other and come back again to system tab, the selected machine get listed under system's tab. Expected results: No backtrace should be there in production.log.
