Are you creating this new FXComboBox (or FXListBox) sometime after 
you've already made the initial call to FXMainWindow#create? If so, you 
probably just need to call #create on the FXComboBox after constructing 
it, i.e.

     @components[component] = FXComboBox.new(...)
     @components[component].create

For a little more information about why this is so, please refer to the 
FOX FAQ topic "When I construct a window at the beginning it works, but 
when I construct it later it doesn't":

Hope this helps,
