[pve-devel] [RFC PATCH widget-toolkit] comboGrid: set errorMask on store load failure

[Dominik Csapak <d.csapak@proxmox.com>]

if there occured an error in the api call of the store, show this error
on the picker when opened, instead of just showing an empty picker

this makes it possible to see that there was an error while accessing the api

altough i tested this, i'd like for someone else to test it too, since
we basically use this anywhere and i am not sure if i forgot some edge
case...
