plz plz help
I am getting the same error ! Plz help !!
data=complainmaster.getSubscribermaster().getSettopboxmaster().getVcnumber().toLowerCase();
ListModel listModel = new SimpleListModel(data);
SimpleListModel() doesn't accept String as input.
You may look into the api.
It's harder to find such problem in zscript,
It would be easy to found such bug, if using java syntax check.
