I can make the combo box and make it show the relevant information. But 
what will the comboChanged event handler look like? Note that I'm not 
interested in getting the text fra the combo, but getting the actual 
object: if item #2 i chosen from the combo, I want a reference to the 
2.nd object in the ArrayList. Somehow I need to get the index number of 
the chosen item.

Best regards,
