Hi
I got it, there was a bug on my class, getRowCount() returned a null value,
because  I used a vector which was not initialized until I called a setup
function, so when I made an instance of my class, my vector.size() returned
a null value. The only strange thing ist that with jdk 1.2. the bug didn�t
appeared but in jdk 1.2.2 it did.
Thanks anyway
Hilde
p.d. there is always something to learn
