RE:JComboBox

Posted by Kishori Sharan on August 10, 2000 at 11:46 PM

Hi
I think somehow all but the first element of the vector is null and that is why it is displaying only one element. I have used the following program to add 100,000 string objects in vector which in turn is used to initialize the JComboBox and it works fine. But when I made all element in vector but the first one null it displays only one. Please check your code when you add elements in the vector and make sure they are not null.
Thanx
Kishori
