people using action form field

[Julio Cesar De Salvo]

I know this is a javascript question but is related with struts.
 
If you use a field called "action" in the form, how can you change the
form action with javascript.
When I try to set the document.form.action it tries to set the field
instead of the action for the form.
Is there any other way to change the action for the form?
 
Thanks, Julio
