Hi Isomorphic,
please see this 5.1p based testcase (v10.1p_2017-08-20).
As you can see in the video (wait a bit, slow because of FF26 dev mode, but happens also compiled in GC60), the buttons are not updated until the data is reloaded via invalidateCache(). This does only happen in a grouped ListGrid.
Best regards
Blama
