Mark,
Thanks a lot for your mails. I have used "action" as a form bean property and not as a
parameter in struts-config. Unfortunately, the Javascript function doesn't seem to
work...it does not set the value of the ActionForm property, "action".
When I tried to print out the value of the "action" property in my ActionClass,
I got a null value.
I tried the following code in my Action class and I got a null value.
String action = ((ActionForm) form).getAction();
Wonder if I have missed something.

Its better that this is posted to the list as well, after all its a
good question and hopefully an adequate answer.
function lookup(form) {
form.elements['action'].value = "lookup";
form.submit();
}
//-->
...
[input]
//struts config
name="myForm" redirect="false" parameter=""action" />
The only thing you'd have to watch would be if the client didn't
support javascript then you'd lose lookup, this would make a case for
having action as a form bean property and have some relevantly named
form elements in noscript tags. If lookup isn't mission critical then i
guess you could let this slide.
