Re: [ovirt-users] Uncaught exception occurred. Cannot read property 'f' of null

Hi, We have ovirt connected to our freeipa domain. Things work fine generally, but once in a while I get the following error pop up in the ui: Uncaught exception occurred. Please try reloading the page. Details: Exception caught: Exception caught: (TypeError) __gwt$exception: <skipped>: Cannot read property 'f' of null Please have your administrator check the UI logs

The log that goes with it: 2016-10-17 16:31:32,578 ERROR [org.ovirt.engine.ui.frontend.server.gwt.OvirtRemoteLoggingService] (default task-21) [] Permutation name: 430985F23DFC1C8BE1C7FDD91EDAA785
