About Preserve Identities
Px pages utilize as an underlying model the Niagara component model, which means that every widget in your page is a component.
When a widget is a child of a parent component, for example, when adding a label as CanvasPane’s child, its parent gives it a name, because every child slot of every component must have a name.
Preserve Identities is an option that decides how the names of widgets in Px pages are stored.
To learn more on how to change its value, see the “Px Editor” section in .
