Hi Jerome!
Thanks a lot for your help and I already read the article and tried for
another several hours. Unfortunately I still can only get one half
working. Here is the new code for the event propagation:
ComboBox {
id: combo
width: parent.width
model: mymodel.items // order is important
currentIndex: getCurrentIndex(mymodel.items, mymodel.item)
onCurrentIndexChanged: mymodel.item = model[currentIndex]
textRole: 'name'
Component.onCompleted: {
combo.modelChanged.connect(modelUpdated)
}
function modelUpdated() {
console.log('model updated')
// tried to set the index here but the vaue is already
overriden
}
}
With this the model is loaded first and then the index is set to the
correct initial value. But with this solution I can only append to the
model once and after the append, the index will be wrong.
I also don't seem to be able to save the currentIndex at the right
time. Therefore a small working example would really be great!
My updated code is again at:

Thanks a lot,
Fabian
