ComboBox preselection overwrites item list

Message 1 in thread

I want to preselect the item "b" in the script below, however this
overwrites the itemList and changes the drop-down list to ["b", "b",
"c"]. Is this a bug or am I doing something wrong?

function test()
{ 
    var d = new Dialog; 
    d.caption = "Test"; 
    d.okButtonText = "OK";
    d.cancelButtonText = "Cancel"; 

    var c = new ComboBox;
    c.label = "Select: ";
    c.itemList = ["a", "b", "c"];
    c.currentItem = "b";
    d.add( c ); 
        
    d.exec();
}

Hi, Seneca.

This is a bug in QSA, unfortunately. It will be fixed for maintenance 
releases QSA 1.2.1 and QSA 1.1.4. Meanwhile, here's a patch for QSA 1.2.0.

best regards,
Eskil
