tested on demos in RW mode (commented out transaction throw/break and no initPreventModification):

• after edit: Card is not updated
• after delete: Card is not removed from the View
• after add: Card reloads (completely, and also quite slow with all ~250 countries CardDeck items on 1 page)

in RO mode (default):

• after add: no reload at all
• edit/delete testing is useless, until CardDeck updates correctly in RW mode, but then the same reload behaviour in RW/RO demos is expected

Dedup the reload code with Crud. Crud currently works as expected.
