Wrong values submitted when submitting a form with javascript

Question

Hi guys, I know this aint a struts forum, but I did not know where else to go. So here goes..
I have the following code in my jsp
<logic:iterate id="ex" name="myForm" property="users">
<html:multibox property="deleteUsers">
<bean:write name="ex" property="userId"/>
</html:multibox>
</logic:iterate>
I have about 10 users of which 5 have already been marked for deletion from another action. So basically, the above tag renders 10 rows with a checkbox in the beginning to select users to delete. Also 5 of them have been checked already, I mean when the form is loaded. So checkboxes 1, 4, 5, 8, 10 have already been checked. Now I have a link on which goes like this
Select None. On this I call a javascript which does the following
function uncheckAll() {
for (i = 0; i < 10; i++) {
document.myForm.deleteUsers.checked = false;
This unchecks all my checkboxes.
Now comes the problem. I am submitting the form using a javascript which is invoked on clicking on the submit link using document.myForm.submit(); The problem is the deleteUsers property in myForm still retains the old values. If the checkboxes are unchecked no values should be submitted for this and the deleteUsers array should be empty. Can anyone help me out on this.
Thanks.

Answer 1

Checkboxes only submit a value when they are "on"
They submit nothing if they are not selected.
The problem comes - do you interpret no checkbox values as "clear all values" or "leave the values alone"? Struts assumes the latter.
Your form is probably being kept in session?
Try implementing the reset() method of your action form and set its property to be equivalent to no checkboxes selected.
