Subject: [PATCH] applets/kickoff: recalculate app model binding on rootModel
refresh
Kickoff stores (a pointer to) the most recently accessed app category
(including the all-apps category, but not favorites) through a binding
chain fetching the rootModel's modelForRow() on the current index of the
sidebar. That's a method call that does not by itself create a qml
dependency on the main model state, so if the user installs or removes
software, the underlying model is replaced completely (and the existing
one is deleted), but the binding is not updated to point to the new
(sub)model. Accessing the same category again will then fail (as it
reads the old model, now null), until the user selects a different
category first, changing the index and causing the binding to be
reevaluated.
Instead, reevaluate the binding whenever the rootModel is refreshed.
BUG: 504891
