buildbot nine - force a build shows empty UI

[Basti]

i have some trouble with the force build window in the UI.

If i click on the "force" button, shown in the builder, the window which will be shown is always empty. (see screenshot).

This happens for me also with a clean setup (on a new VM and new builbot sources from githup)

When i use Firebug and click on the force button, i get the following error

Error: e.field is undefined
