Dead QML elements receiving signals?

[dirkcuys]

I have code similar to the following:

@...
id: myComponent
signal updateState()
property variant modelList: []
Repeater {
model: modelList
MyButton {
...
Connection {
target: myComponent
onUpdateState: {
...
}
}
}
}@

I assign a value to modelList and then issue myComponent.updateState() to update the MyButton components in the repeater. At this point I get a lot of warnings about non existent properties

It seems like the signal gets passed to the MyButton(s) that doesn't exist anymore (since the repeater will rerun when I change modelList).

Is there a way of avoiding this or should I simply ignore the warnings?
