WIP: Freezing when submitting a Business Unit / Machine Group

[mosen]

in v6, precursorca found an issue saving BU's / machine groups:

MR6 Business Units / Machine Group creation forms have a glitch.
It shows a Submit button AND a Save button. Clicking either results in the page freezing.
But if you immediately Sign Out and then log back in to MR6 you find the Business Unit / Machine Group has indeed been created.

Does not freeze for me so need to repro.
The new BU does get appended without any padding though, so it looks horrible.
Also adding a machine group straight after does not pick up the name you entered.

Fixed an issue adding new machine groups to a BU.
Still does not generate a groupid/key when creating a BU

A key difference is in the frontend: v5 will submit form values for "key", "keys", and "groupid" if creating a new business unit, but this doesnt seem to make sense
