Post a small section(s) of your code that's creating, loading and displaying the combo box.

I don't know exactly what's going on in your application, so maybe my tip won't be helpful.

What you can do is store the employees in an array, and you can use the Arrays class to binary search through the array (Arrays.binarySearch)

if the employee that you're going to add to the combo box was already added to the combo box, then when you binarysearch the array you will get a value above 0. If it didn't find that value in the array you'll get a negative number
