Hi Bea,
thanks a lot for your help. With the code you provided, I managed to
adapt my code to solve the problem. Having a ListView inside a ListView
when only really using one ListView is a bit counter intuitive at first,
but maybe I just need to adjust to the QML way :)
Anyways, I'm looking forward for improved model/view features in the
future.
Thanks again!
Conny
