Subject Re: Checkbox problem?
Date Tue, 10 Jun 2003 18:11:14 GMT
You are missing my point! If I just could set the checkbox value to
false in the reset method, everything is fine. But there are times when
that value has to be reset to true and not false and if I do that in my
reset method, I am not able to see of the user unchek the checkbox,
because the boolean variable is still true after the form has been
posted!
