I have to populate simple combobox,so on Submit button <option values > for combobox should be carried through request global,and action should stay on same page.

But when I debug jsp I see that request stays empty???

Also combobox behave funny,it changes value when pressed any button on page???

form from line 55 to 65 behaves funny

here's the code:
