Description
Using a required property appears to break model data injection inside delegate objects:
component Node : ListView {
required property ListView owner
}
Node {
id: rn
owner: null
model: 1
delegate: Node {
id: l1
owner: rn
model: 1
property int ii: index
property int dd: modelData
delegate: Node {
owner: l1
model: 1
property int ii: index
property int dd: modelData
delegate: Text { text: index + " " + modelData }
}
}
}
The result is index and modelData cannot be resolved for any but the innermost view.
qrc:/main.qml:30: ReferenceError: modelData is not defined
qrc:/main.qml:29: ReferenceError: index is not defined
qrc:/main.qml:25: ReferenceError: modelData is not defined
qrc:/main.qml:24: ReferenceError: index is not defined
Simply omitting the `required` keyword produces a runtime with no errors.
Additionally, nesting each subsequent Node inside any qml object instance (not Component tho) also appears to "fix" it and everything is resolved properly:
Node {
id: rn
owner: null
model: 1
delegate: Row { Node {
id: l1
owner: rn
model: 1
property int ii: index
property int dd: modelData
delegate: Row { Node {
owner: l1
model: 1
property int ii: index
property int dd: modelData
delegate: Text { text: index + " " + modelData }
} }
} }
}
The above snipped does work with required property.
This time the problem is not related to inline components, it is the same if Node is defined in its own source.
