Using this QQC2 this example fails to start:
``````````
import QtQuick 2.9
import QtQuick.Controls 2.2

SpinBox {
  from: 1; to: 50
  value: 5
  onValueModified: console.log(value)
}
`````````````````
it returns:
"SpinBox.onValueModified" is not available due to component versioning.

First I called this issue on: [1]
but only frameworks-qqc2-desktop-style causes this issue.
In [1] may be a clue of possible reason of that wrong behavior.
