When registering a new project, the project short name is validated but the long name is not. Furthermore, the short name is auto-completed from the long name but only when the long name field loses focus.
It would be more useful to have the short name field update and validate on keypress, as the short name field now does.
One consideration, though, is if the user changes the short name, updating the long name should not overwrite the manual change.
