From memory, this happens if you call removeAll() on the combo, which
causes the Container superclass to remove all the components that were
used to give the combobox its appearance. (Results may vary from one
PLAF to the next on this, don't know but it seems likely enough.)

You probably mistakenly called removeAll() when you were intending to
call removeAllItems(). They do very different things.
