The Editor doesn't allow multiple separators through the tools configuration.
Only the first separator is rendered.
All the separators should be rendered

Turns out even if you mess up and name them both sep1 it works! So its not that they need unique names, they just need names.
Came here as I have the same problem using the editor for MVC, but I think in the case of Kendo UI you just need to name the separators differently. I have updated your dojo @Tom - see that specifying the names "sep1" and "sep2" resolves the problem

However you cant do this using the MVC builders - the EditorToolFactory doesnt allow for a 'name' to be set when building a .Separator()
