Many "ReferenceError: propertyName is not defined" errors are printed.

1. Use CardsGridView with a model 
2. Create a delagte using roles other than display

It does not work. Many "ReferenceError: propertyName is not defined" errors are printed.

EXPECTED RESULT

ADDITIONAL INFORMATION

Removing `default property alias delegate: root._delegateComponent` from CardsGridView.qml fixes the problem
Comment 1 Emmanuel Lepage Vallée 2018-12-11 11:00:49 UTC 
Apparently this can be mitigated using `model.roleName` instead of `roleName`. Still, it should be a drop-in replacement so it is still a bug.
Comment 2 Matej Starc 2022-09-24 16:09:52 UTC 
Sadly, DelegateRecycler has to be used because ``ActionsToolBar`` has problems without using it. Try using CardsGridView without DelegateRecycler and try scrolling up and down really fast (you have to have a model of more than 50 items).
