You're right... shame on me

I was running the for Loop for the Data fill in the Construktor of the Dialog (after setupUi()) and the Debug Code in a slot called by a Button click (the Displayed comboBox looks good and the qDebug for the text delivers me the right entry)

Tried it with 5.1.0 and 5.0.2, same Problem, now I will try it in a complete new project, with nothing but the combobox
