Trying to rename a prototype component in "Class Design" window when prototypes are not shown throws an NRE error.
1. Create a prototype component
2. Open "Class Design" Window.
3. Select a ship, use Wide View, Check "Prototypes" checkbox
4. Add the created component to a ship
5. Uncheck "Prototypes" checkbox
6. Select the new component from the ship
7. Hit "Rename Comp" button
8. Choose a name and confirm
9. Error: Function #278 Null Reference Exception
The component does get renamed, but not immediately reflected in the window.
