Description

Notebook's not loading if one of the notename contains '/'

It will have a exception :

TypeError: Cannot read property 'length' of null

Workaround : Rename the note with name '/'

Root cause :

var nodes = noteName.match(/([^\/][^\/]*)/g);

when we are trying to match the parent and child notes with regex expression in javascript its failing with no match as the name itself is '/'
