I can't save anything in kmenuedit application. Tried creating a new item and then a new sub menu but it doesn't appear on the menu after saving. I'm using Opensuse Leap 42.2
Confirmed using: Ubuntu 16.04.1 LTS kmenuedit Version 5.8.4 KDE Frameworks 5.28.0 Qt 5.6.1 (kompiliert gegen 5.6.1) Das xcb Fenstersystem
Re-checked again in System from Comment 1 and in a VM with up to date neon devedition gitunstable and read the Handbook of KMenuEdit on docs.kde.org, where the issue with Items without command is mentioned: 1) An Item needs Name + Command to be displayed and saved, otherwise these changes are lost even if KMenuEdit ask to save the changes and you confirm. 2) A submenu needs at least one valid Item (with Name and Command) to be displayed, but is saved also without a valid item 2) Submenus are always saved also without a valid Item in their tree 3) A toplevel Submenu with a valid Item (with Name+Command) is only displayed using the Application Launcher on the page Applications; but not using the Application Menu 4) A valid toplevel Item (with Name+Command) is never diplayed, neither in Application Launcher nor in Application Menu Do you have this behavior in your Opensuse Leap 42.2 as well?
