This is the scenario that I was trying to figure out.
Suppose in the struts config file I've defined a form bean name "logonForm"
and an action named "/logon" which uses "logonForm". And suppose that
in validate.xml I've defined
<formset>
<form name="logon">
...
</form>
<form name="logonForm">
...
</form>
</formset>
When the user clicks on a button that triggers a form submit
via the logon action... What validation takes place?
Maybe my question should be: When does validation for form bean
gets triggered? Is it any time that an action uses it or?

Does this apply to something like this as well?
<formset>
<form name="duplicateValidation">
...
</form>
<form name="duplicateValidation">
...
</form>
</formset>
Thanks!
