Broken schema editor after update from 2.7 to 2.8

Hi,

it seems that the schema editor is broken in 2.8. Maybe it’s releated to updating from 2.7 to 2.8.
There is no way to create or edit schemes. After selecting a db, the editor opens the section for creating db fields with everything grey’ed out. Pressing Save/Cancel has no effekt.

I did not try a fresh 2.8 instal yet.

Can anyone confirm that?

UPDATE:

It seems that the update from 2.7 to 2.8 broke the editor. With a fresh installed instance, there is no problem.
